Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
1 and 2 show the overall configuration of the product registration system, and 1 is a product mounting table. The customer 2 puts the products 3, 3,... Attached with the registration wireless tags in the attached basket 4 and places them on the product placement unit 5 of the product placement table 1. A weight scale 6 for weighing the products 3, 3,... In a basket 4 is provided at the center of the product mounting table 1, a wireless tag reader 7 is installed on one side of the weight scale 6, and The antenna 7 a of the wireless tag reader 7 is arranged on both sides of the weighing scale 6.

  The store clerk 8 moves the basket 4 placed on the product placement unit 5 of the product placement table 1 onto the weighing scale 6 and operates a key of the operation unit 9a of the registration settlement apparatus 9 to generate a reading command. When a reading command is issued from the registration / accounting device 9, the wireless tag reader 7 inquires the wireless tag attached to each product 3 in the basket 4 via the antenna 7a by wireless electromagnetic waves, Product information is received by response. When the wireless tag reader 7 receives product information from the wireless tag, the wireless tag reader 7 transfers the product information to the registration settlement apparatus 9.

  When receiving the product information from the wireless tag reader 7, the registration settlement apparatus 9 searches the product information file based on the product identification code of the product information, reads the product name, product price, etc. of the corresponding product and performs registration processing. . In this case, if there is a product weight value in the product information from the wireless tag, the weight value is added to the memory and stored, and the product information from the wireless tag does not have the product weight value and corresponds to the product information file. When there is a weight value of the product, the weight value is added to the memory and stored.

  When the wireless tag reader 7 confirms receipt of the merchandise information for all the merchandise 3 in the basket 4, it transmits a reading end signal to the registration settlement apparatus 9. Upon receipt of the reading end signal from the wireless tag reader 7, the registration and settlement apparatus 9 adds the weight value obtained by subtracting the preset weight value of the basket 4 from the weight value from the weight scale 6 and each product stored in the memory. If the difference is within the allowable range, the display unit 9b displays that the registration is correctly completed and displays the total amount of each product. Then, the clerk 8 receives the price from the customer after moving the basket 4 placed on the weighing scale 6 to the position of the settlement unit 10 of the product placement table 1, and receives the receipt issued by the registration settlement unit 9 as the customer. Hand it over. Also, if you have fishing, you will also hand change.

  The customer 2 receives the basket 4 from the settlement section 10 and places it on the work table 11, where the product 3 in the basket 4 is packed in a prepared take-out bag. At this time, the wireless tag is peeled off from each product 3 and put into the duck inlet 12a of the tag collection device 12. The tag collection device 12 counts the number of wireless tags inserted into the duct inlet 12a and displays the count value on the display unit 12b. Then, when the customer instructs the end of insertion, the tag collection device 12 discharges the refund money corresponding to the number of returned wireless tags from the payment port 12c. The customer receives this and leaves the store.

  In this way, when the customer peels off the wireless tag from the product 3 and inserts it into the tag collection device 12, the refund money is discharged from the payment port 12c in accordance with the number of inserted wireless tags, so the wireless tag is returned to the customer. By doing so, a refund service can be received, and for the store, the returned wireless tag can be reused, so that the cost of using the wireless tag can be reduced. Further, the return of the wireless tag can be promoted, and the collection rate of the wireless tag can be improved.

  Further, if the difference between the weight value obtained by subtracting the weight value of the basket 4 from the weight value from the weight scale 6 and the total weight value of each product added and stored in the memory is out of the allowable range, the display unit 9b A discrepancy is displayed to inform the clerk 8. As a result, the clerk 8 sorts out the products 3 in the basket 4 to some extent and then causes the wireless tag reader 7 to read again. If the second time does not match, the product 3 in the bag 4 will be revised separately.

Next, the configuration of the registration wireless tag attached to the product will be described.
As shown in FIG. 3, the registration wireless tag 13 is of a card type, has a plane dimension that is about half that of, for example, an ISO card (about 86 mm × 54 mm), and is mounted with a circuit element such as an IC chip.

A first adhesive layer (shaded portion in the figure) 14g is provided at the center of the RFID tag attaching portion 142 of the base paper 14a so as to cover the comb-shaped conductive patterns 14d1, 14d2 and the second cut portion 14f. . The first cutting part 14e is used to prevent the pre-printing part 141 from being broken when the registration wireless tag 13 once pasted on the display label 14 is peeled off. The cutting portion 14f is for cutting the connecting portions P of the comb-shaped conductive patterns 14d1 and 14d2 when the registration wireless tag 13 is peeled off.

A second adhesive layer 14h is provided over the entire back surface of the base paper 14a, and the base paper 14a is pasted on the base paper 15 that has been subjected to silicone coating on both sides via the second adhesive layer 14h.
As shown in FIG. 8, a large number of display labels 14 are affixed and arranged on the mount 15, which is formed by cutting the raw material obtained by bonding the base paper 14 a and the mount 15 into a strip shape. Thereafter, thick printing of the pre-printed portion 141 and the comb-shaped conductive patterns 14d1 and 14d2 is performed on the base paper 14a, and the first cut portion 14e and the second cut portion 14f are inserted, and further the comb-shaped conductive patterns 14d1, 14d2 and the first The first adhesive layer 14g is formed on the two cut portions 14f.

FIG. 9 is a diagram showing a state in which the registration wireless tag 13 is adhered onto the first adhesive layer 14g of the display label 14, and the comb-shaped conductive patterns 13g1 and 13g2 of the wireless tag 13 are the comb-shaped conductive patterns of the display label 14. The patterns 14d1 and 14d2 are bonded so as to coincide with each other. At this time, the wireless tag 13 and the display label 14 have an asymmetric positional relationship in the x direction and the y direction.
FIG. 10 is a diagram showing a state in which a number of display labels 14 are pasted on a belt-like mount 15 and a wireless tag 13 is adhered thereto.

Next, an apparatus for manufacturing such a labeled wireless tag will be described.
As shown in FIGS. 11 and 12, a label supply roll 21 in which a large number of display labels 14 are affixed to a belt-like mount 15 as shown in FIG. The display label 14 is transported along the transport path 23 together with the mount 15 from the label supply roll 21.
The transport path 23 is provided in the central portion on the apparatus main body 20, and a label position detection unit 25, a tag mounting mechanism 26, a tag rewriting unit 27, and a label printing unit 28 are arranged along the transport path 23. . The tag rewriting unit 27 and the label printing unit 28 are arranged facing the same position with the conveyance path 23 therebetween. A control unit 24 is also arranged on the apparatus main body 20.

  In this apparatus, first, the mount feeding roller 29 is operated in response to the mount feed signal from the control unit 24, whereby the mount winding shaft 30 is operated to wind the mount 15, and the label supply roll 21 is The display label 14 is conveyed together with the mount 15 by rotating. When the label position detection unit 24 detects four cross marks 14c on the label, the operation of the mount sheet feeding roller 29 is stopped to stop the conveyance of the display label 14. Thereafter, the mount feeding roller 29 repeats the operation of feeding the display label 14 by one pitch every time it receives a mount feed signal from the control unit 24.

  When the label position detection unit 24 detects four cross marks 14c on the display label 14, it reads the accurate position of the display label 14 such as the rotation angle with respect to the x direction, the y direction, and the reference direction, and transmits it to the tag mounting mechanism 26. To do. The tag mounting mechanism 26 drives the robot arm 26a to take out the registration wireless tags 13 one by one from the tag holder 31 by suction and holds them on a predetermined position of the display label 14, that is, on the first adhesive layer 14g. Let At this time, the comb-shaped conductive patterns 13g1 and 13g2 of the wireless tag 13 are aligned with each other with high precision so as to overlap the comb-shaped conductive patterns 14d1 and 14d2 of the display label 14.

  FIG. 14 is a plan view showing a state in which the registration wireless tag 13 is adhered to a predetermined position of the display label 14. The conductive patterns 14d1 and 14d2 of the display label 14 and the conductive patterns 13g1 and 13g2 of the wireless tag 13 coincide with each other and overlap each other. 15, the conductive pattern 14d1 and the conductive pattern 13g1 face each other with the resin film 13a in between, and the conductive pattern 14d2 and the conductive pattern 13g2 have the resin film 13a in between. Since both of them constitute a capacitor as shown in FIG. 16 (a) and the conductive patterns 14d1 and 14d2 are connected, they are equivalently shown in FIG. 16 (b). One capacitor is formed in each.

  The display label 14 to which the registration wireless tag 13 is bonded and fixed is conveyed one pitch at a time, and then reaches the position where the tag rewriting unit 27 and the label printing unit 28 are arranged. When the display label 14 reaches this position, first, the tag rewriting unit 27 transmits a rewriting electromagnetic wave from the antenna 27a by a rewriting signal from the control unit 24, and rewrites the contents of the memory of the registration wireless tag 13. That is, if the product information is already stored in the memory, the product information is rewritten to the predetermined product information. If the product information is not stored in the memory, the predetermined product information is written. Then, when the tag rewriting unit 27 finishes transmitting the rewriting electromagnetic wave, the tag rewriting electromagnetic wave is transmitted next to read the contents of the rewritten product information, and confirms the coincidence with the information to be rewritten. If they do not match, the rewriting electromagnetic wave is transmitted again and rewriting is performed, and this is repeated a predetermined number of times until the matching with the information to be rewritten is confirmed. When the match with the information to be rewritten is confirmed, the tag rewriting unit 27 transmits a rewriting end signal to the control unit 24.

  When the control unit 24 receives the rewriting end signal from the tag rewriting unit 27, it transmits a printing signal to the label printing unit 28 this time. When the label printing unit 28 receives the print signal from the control unit 24, the label printing unit 28 prints predetermined product information in the frame 14 b of the pre-printing unit 141 of the display label 14, and when printing is completed, the print end signal is sent to the control unit 24. Send. When the tag rewriting unit 27 rewrites the memory contents of the registration wireless tag 13, if the tag is damaged in some way and the product information cannot be rewritten a predetermined number of times, the tag rewriting unit 27 performs control. A signal that cannot be rewritten is transmitted to the unit 24. As a result, the control unit 24 transmits an instruction to print the tag abnormality to the label printing unit 28, and the label printing unit 28 performs printing to display the tag abnormality on the display label 14.

  The RFID tag T with label that has been printed is partially peeled off from the backing paper 15 by the backing paper folding unit 32, and the RFID tag T with the label partially peeled off is completely peeled off manually or by an automatic pasting device. The adhesive layer 14h adheres. For example, it is peeled and removed by manual work, and is adhered to the product 35 on the weighing scale 34 placed on the work table 33. The label sensor 36 detects that the labeled wireless tag has been peeled off from the mount 15, and the mount 15 from which the labeled wireless tag has been peeled is wound around the mount take-up shaft 30 via the mount feed roller 29. It is done. Reference numeral 37 denotes an operation unit of the apparatus main body 20, and 38 denotes a bar code reader.

  FIG. 13 is an enlarged view from the arrangement part of the tag rewriting unit 27 and the label printing unit 28 to the mount folding unit 32 for peeling the labeled wireless tag T, and the mount folding unit 32 is an R position for performing tag rewriting and label printing. Since the label-attached RFID tag T1 is located at a distance L1 from the tip position S in the feed direction of the label, the next mount feed operation stops in a state where a part of the label-attached RFID tag T1 is attached to the mount 15; The operation of peeling the attached wireless tag T becomes easy, and the operation of attaching the labeled wireless tag T to the product 35 is also facilitated. In addition, since the distance L1 from the tip position S of the labeled wireless tag T1 at the R position to the mount folding portion 32 is sufficiently smaller than the length L2 in the feed direction of the labeled wireless tag T, the labeled wireless tag When the target product to be attached with the tag T is switched, no RFID tag T with a label that is wasted by printing between the R position and the mount folding unit 32 is generated. Further, the tag rewriting unit 27 and the label printing unit 28 are arranged at the same position, and the product information of the wireless tag 13 is first rewritten by the tag rewriting unit 27, and the product information is rewritten after being correctly rewritten. Since the label printing unit 28 performs printing on the display label 14, it is possible to prevent wasteful generation of the labeled wireless tag T in this respect as well.

The product information stored in the memory of the registration wireless tag 13 differs depending on the type of product, and can be classified into three groups of product groups A to C.
A product in the product group A is a product that is mass-produced at a factory, and this product usually has a printed barcode called a source code. If this product is the same product, the variation of each weight is very small, and the change with time is very small. Since the products of this product group A have the same price and the same weight as long as they are the same product, if product information such as the price and weight value of this product is stored separately in this product information file, The information stored in the memory of the wireless tag 13 attached to the product of the product group A may be only the product identification code.

The products of the product group B are products that are set and sold at a price per unit weight, and are generally products that are packaged, weighed, and priced in a store or a distribution center in the vicinity thereof. Even if this product has the same product identification code, individual weight values are often different. Accordingly, the information stored in the memory of the wireless tag 13 attached to the product requires the product identification code, the product price, and the product weight value.
In addition, the products in the product group C are products that are sold at a fixed price, and are generally products that are packaged and priced in a store or a distribution center in the vicinity thereof. Even if this product has the same product identification code and price, there is variation in weight. Therefore, as information to be stored in the memory of the wireless tag 13 attached to the products of the product group C, a product identification code and a product weight value are required.

  For example, the rewriting of the memory of the wireless tag 13 for registration of the wireless tag T with label attached to the product of the product group A and the printing of the product information on the display label 14 are performed by using the operation unit with the product identification code of the target product 35. The key code is input from 37 or the source code printed on the product 35 is read by the bar code scanner 38 and transferred to the control unit 24. The control unit 24 reads product information corresponding to the product identification code from the built-in product information file. In the case of the products in the product group A, only the product identification code is transferred from the control unit 24 to the tag rewriting unit 27, and the product name and price are transferred to the label printing unit 28. Rewriting and printing on the display label 14 are performed. The manufactured RFID tag T with label is removed after being conveyed to the mount folding section 32 and attached to the product 35 on the work table 33. In the case of this product, since the weight value is determined, the weigh scale 34 is unnecessary.

  In addition, in the case of the products in the product group A, a large number of labeled RFID tags T are attached together for the same product. In this case, the operation unit 37 presets the number of products and inputs the product identification code. I do. Thus, each time the label sensor 36 detects that the labeled RFID tag T has been removed by the mount folding unit 32, the RFID tag 13 is attached by the tag attachment mechanism 26, and the RFID tag 13 by the tag rewriting unit 27 is attached. The product information is rewritten and the product information is printed on the display label 14 by the label printing unit 28 once, and this is repeated for a preset number of times.

  In addition, the rewriting of the memory of the wireless tag 13 for registration of the wireless tag T with label attached to the product of the product group B and the printing of the product information on the display label 14 are performed by using the operation unit with the product identification code of the target product 35. The key input from 37 is transferred to the control unit 24. Since the products of the product group B are products that are set and sold at a price per unit weight, the weight scale 34 is placed on the work table 33. When the product 35 packed in advance is placed on the weighing scale 34 and weighed, the weight value data is transmitted from the weighing scale 34 to the control unit 24.

  The control unit 24 reads product information corresponding to the product identification code from the built-in product information file. In this case, the product name and the price per unit weight are read from the product information file. Then, the price of the product is obtained from the price per unit weight and the weight value data from the weigh scale 34. In the case of products in this product group B, the product identification code, product weight and product price are transferred from the control unit 24 to the tag rewriting unit 27, and the product name, price per unit weight and product weight are transferred to the label printing unit 28. Information such as the product price and the raw materials constituting the product, the date of manufacture, the expiration date, etc. are transferred as necessary, whereby the product information of the wireless tag 13 is rewritten and printed on the display label 14. The labeled RFID tag T manufactured in this way is transported to the mount folding unit 32 and then removed and attached to the product 35 on the weighing scale 34 of the work table 33.

  In addition, the rewriting of the memory of the wireless tag 13 for registration of the wireless tag T with label attached to the product of the product group C and the printing of the product information on the display label 14 include the product identification code of the target product 35 as the operation unit. The key input from 37 is transferred to the control unit 24. The products in the product group C are products that are arranged at substantially the same weight and are sold at the same price. However, since there is a variation in the weight, the weighing is performed by the weigh scale 34 as in the case of the product group B. That is, when a product 35 that has been packed in advance is placed on the weighing scale 34 and weighed, weight value data is transmitted from the weighing scale 34 to the control unit 24.

The control unit 24 reads product information corresponding to the product identification code from the built-in product information file. In this case, the product name and the product price are read from the product information file. In the case of the products in the product group C, the product identification code and the product weight are transferred from the control unit 24 to the tag rewriting unit 27, and the product name, product weight, product price, and the product as required are supplied to the label printing unit 28. The information such as the raw material, the date of manufacture, and the expiration date is transferred, and the product information of the wireless tag 13 is rewritten and printed on the display label 14. The labeled RFID tag T manufactured in this way is transported to the mount folding unit 32 and then removed and attached to the product 35 on the weighing scale 34 of the work table 33.
In this way, the operation of attaching the labeled RFID tag T to each product of the product groups A, B, and C is performed, and these products are arranged on a product display shelf in the store.

Each is designed to supply power. In addition, when the product information is rewritten, the wireless tag 13 demodulates the signal received by the antenna 13f by the demodulator 57 and then supplies the demodulated signal to the digital processing unit 52. The digital processing unit 52 controls the memory 53 to control the memory 53. The product information 53 is controlled to be rewritten, and a rewriting end signal for completing the rewriting is modulated by the modulator 56 and then radiated as an electromagnetic wave from the antenna 13f. Further, when reading the product information, the wireless tag 13 demodulates the signal received by the antenna 13f by the demodulator 57 and supplies the demodulated signal to the digital processing unit 52. The digital processing unit 52 controls the memory 53 to control the memory 53. The product information is read from 53, and the read product information is modulated by the modulator 56 and then radiated as an electromagnetic wave from the antenna 13f.

  FIG. 19 is a circuit block diagram showing a specific configuration of the demodulator 57. The demodulator 57 is a PLL (phase looked loop) demodulator, and includes a PDET (phase detector) 571, a VCO (variable capacitance oscillator) 572, and an LPF (loop filter) 573. The frequency-modulated signal received by the antenna 13f is demodulated by the PDET 571 based on the basic transmission frequency from the VCO 572, and is output as a digital signal from the LPF 573.

  FIG. 20 shows a specific circuit configuration of the VCO 572. A parallel circuit of a series circuit of capacitors C1 and C2 and a series circuit of a coil L and a capacitor C3 is provided, and an NPN transistor Tr is connected in parallel to the capacitor C2. A series circuit of a capacitor C4 and a variable capacitance diode CV is connected in parallel to the capacitor C3. The connection point between the capacitor C2 and the coil L is connected to the output terminal OUT via the capacitor C5, and the connection point between the capacitor C4 and the variable capacitance diode CV is connected to the feedback input terminal VT. This VCO 572 feeds back the differential signal voltage from the LPF 573 to the feedback input terminal VT, thereby changing the capacitance of the variable capacitance diode CV, and the frequency and phase of the output signal from the output terminal OUT are locked to the input signal. To control. The capacitor C3 of the VCO 572 is formed by superposing a pair of conductive patterns 13g1, 13g2 of the registration wireless tag 13 and a pair of conductive patterns 14d1, 14d2 of the display label 14. That is, as shown in FIG. 16, the capacitor C3 is formed by the capacity of the conductive pattern 13g1 and the conductive pattern 14d1 and the capacity of the conductive pattern 13g2 and the conductive pattern 14d2.

  Therefore, if the superposition of the pair of comb-shaped conductive patterns 13g1 and 13g2 of the registration wireless tag 13 and the pair of comb-shaped conductive patterns 14d1 and 14d2 of the display label 14 does not exactly match, the capacitance of the capacitor C3 changes greatly. As a result, the oscillation frequency of the VCO 572 exceeds the control range, so that the PLL is out of the lock range, and the wireless tag 13 does not respond to electromagnetic waves instructing reading from the wireless tag reader 7. Therefore, even if only the registration wireless tag 13 is peeled off from the display label 14 and replaced, the pair of comb-shaped conductive patterns 13g1 and 13g2 of the wireless tag 13 and the pair of comb-shaped conductive patterns 14d1 and 14d2 of the display label 14 are accurate. Therefore, the function of the wireless tag 13 can be stopped in such a case.

  In addition, when the wireless tag 13 is peeled off and replaced with the display label 14 attached to the product, the second cutting portion 14f is easily broken and the pair of comb-shaped conductive patterns 14d1 and 14d2 are electrically separated. Therefore, the series circuit of the capacitance due to the overlapping of the conductive pattern 13g1 and the conductive pattern 14d1 and the capacitance due to the overlapping of the conductive pattern 13g2 and the conductive pattern 14d2 is divided. As a result, the capacitance of the capacitor C3 changes greatly. Therefore, also in this case, the oscillation frequency of the VCO 572 exceeds the control range, so that the PLL is out of the lock range, and the wireless tag 13 does not respond to the electromagnetic wave instructing reading from the wireless tag reader 7.

  As shown in FIG. 21, the product information file 44 of the registration settlement apparatus 9 has storage areas for product identification codes, product names, product prices, and product weight values. A product name, a product price, and a product weight value are stored in association with the product identification code together with a product identification code starting with a country code such as “”. For each product in the product group B described above, only the product name corresponding to this product identification code is stored together with the product identification code starting with, for example, “02” indicating in-store marking. For each product in the product group C described above, a product name and a product price corresponding to this product identification code are stored together with a product identification code starting with, for example, “20” indicating in-store marking.

  As shown in FIG. 22, the memory unit 53 of the registration wireless tag 13 is provided with a storage area for a product identification code, a product price, and a product weight value, and each product in the product group A is shown in (a). In this way, only the product identification code is stored, and for each product in the product group B described above, the product identification code, product price, product weight value is stored as shown in (b), and the product group C described above is stored. For each product, a product identification code and a product weight value are stored as shown in (c).

The microprocessor 41 of the registration settlement apparatus 9 is programmed so as to perform the registration process shown in FIG.
First, in S1, the weight of the basket 4 containing the product 3 is weighed by the weighing scale 6. And it waits for generation | occurrence | production of the reading command by the key input of the operation part 9a. In this state, a key operation for generating a read command is performed. When the read command is generated, the wireless tag reader 7 is driven in S2, and an electromagnetic wave is applied to the labeled wireless tag attached to each product 3 in the bag 4. The product identification code is received from any wireless tag. At this time, if the product is a product of the product group A, since only the product identification code is stored in the memory unit 53 of the wireless tag, only the product identification code is received. In addition, since the product identification code, the product price, and the product weight value are stored in the memory unit 53 of the wireless tag for the product of the product group B, the product price and the product weight value are received in addition to the product identification code. . Further, since the product identification code and the product weight value are stored in the memory unit 53 of the wireless tag for the product of the product group C, the product weight value is received in addition to the product identification code.

  Subsequently, in S3, the product information file 44 is searched with the received product identification code, and the product name, product price, product weight value, etc. of the corresponding product are read out. At this time, if the product is a product in the product group A, only the product identification code is received from the wireless tag. Therefore, the product name, product price, and product weight value are read from the product information file 44. Further, in the case of a product in the product group B, reception from the wireless tag is a product identification code, a product price, and a product weight value. Therefore, only the product name is read from the product information file 44. Further, in the case of products in the product group C, the reception from the wireless tag is the product identification code and the product weight value, and therefore the product name and product price are read from the product information file 44.

  Subsequently, in S4, the product name, product price, and product weight value of the corresponding product are registered in the customer-specific file 45. And the process of S2-S4 is repeated until the inquiry with respect to all the wireless tags is complete | finished.

  In this process, since a large number of products 3 are stored in the bag 4, a collision occurs when the wireless tags of the products respond to the inquiry from the wireless tag reader 7 at the same time. Therefore, as shown in FIG. 24, responses are made with different delay times between the wireless tags A to C so that the response signals from the wireless tags A to C do not collide with the inquiry signal from the wireless tag reader 7. The signal is generated. That is, the wireless tag of each product generates a delay time for randomly shifting the response signal with respect to the inquiry signal from the wireless tag reader 7. When the wireless tag reader 7 receives a response signal from one of the wireless tags, the generation of the inquiry signal is stopped for a moment, and this signal is changed to notify the corresponding wireless tag that the product information has been read. The corresponding wireless tag that has received the change of the inquiry signal stops the repetition of the response to the inquiry signal and becomes disabled. In this way, the wireless tag reader 7 sequentially reads product information from the wireless tag of each product 3. Then, if it is determined that there is no response from any wireless tag for a period longer than the maximum value of the delay time of the wireless tag, the wireless tag reader 7 determines that all wireless tags have finished their responses and are in a disabled state, Stop generating the inquiry signal.

  When the inquiry for all the wireless tags is completed, the weight value of only the product in the bag 4 is obtained by subtracting the weight of the bag 4 set in advance from the weight value taken in from the weight scale 6. On the other hand, a total weight value obtained by adding the weight values of all the products registered in the customer-specific file 45 is obtained. Then, the weight value of only the product is compared with the total weight value of all registered products, and it is checked whether or not the difference is within the allowable range.

  If the difference is within the allowable range, it is determined that there is no error in the registered product, and the total amount of the product registered in S5 is displayed on the display unit 9b. Subsequently, in S6, the product name, product price, and total amount of the registered product are printed on the receipt paper by driving the receipt printer 42, and are printed on the journal paper by driving the journal printer 43. As a result, the store clerk receives payment from the customer and hands over the receipt. Finally, in S7, the product identification code, the product price, and the total price of the product for one customer registered in the customer-specific file 45 are transmitted from the host interface 46 to the host computer.

  If the difference between the weight value of only the product and the total weight value of all registered products is out of the allowable range, a message notifying the mismatch is displayed on the display unit 9b in S8. As a result, the store clerk performs an operation of causing the wireless tag reader 7 to read again by changing the position of the product 3 in the bag 4 if any trouble occurs.

Thus, when registration is completed for all the products 3 in the bag 4, the weight value of all the products 3 in the bag 4 is compared with the total weight value obtained by adding the weight values of the registered products. Since it is checked whether or not the registered product content matches the product actually in the bag, even if a malfunction occurs in the reading of the wireless tag reader 7, it is detected and read again. It is also effective when there is an illegal act such as intentionally killing the function of the tag by removing or bending the wireless tag.
If the inconsistency is not resolved even if the position of the product in the bag is changed and read again, the products in the bag are taken out one by one and registered manually.

  By the way, fresh products etc. are included in the products belonging to the product groups B and C among the products, and there are cases where discount sales are performed when the store is close. In order to cope with this, a discount wireless tag 61 is prepared as shown in FIG. That is, the discount wireless tag 61 is provided with a memory portion therein to store discount amount information, print the discount amount on the surface 61a, and form an adhesive layer 61b on the bottom. Of course, the discount wireless tag 61 also includes a circuit similar to the registration wireless tag 13. The discount wireless tag 61 forms a pair of comb-shaped conductive patterns on a base paper by a thick film printing process, and on a label provided with a perforated cut portion so as to cross the pair of comb-shaped conductive patterns. Paste and stick to the product using this label.

As shown in FIG. 26, the store clerk sticks the discount wireless tag 61 separately from the registration wireless tag 13 to the product 3 that is sold at a discount when the store is close.
For the product 3 to which the discount wireless tag 61 is attached, the wireless tag reader 7 reads the product information from the registration wireless tag 13 and reads the discount amount information from the discount wireless tag 61. For the discount amount, a separate memory is provided in the customer-specific file 45 of the registration settlement apparatus 9 and added. When reading is completed and the total amount is displayed on the display unit 9b, the total discount amount is subtracted from the total amount. The total amount after the discount is calculated and displayed. Further, the original total amount, the discount total amount, and the total amount after the discount are printed on the receipt or the journal separately by characters or the like. As for the discount, a discount amount may be attached to the label with a bar code or the like without using a wireless tag, and the store clerk may read the discount amount with a handy type scanner and cause the registration settlement apparatus 9 to capture the discount amount.

(Second Embodiment)
This is because the registration wireless tag 13 has all the weight values of the products, and the product information file 44 of the registration settlement apparatus 9 has a product identification starting from a country code such as “49” as shown in FIG. Each product in product group A having a code, each product in product group B having a product identification code starting from “02”, and each product in product group C having a product identification code starting from “20” The value is not stored.
Instead, as shown in FIGS. 28A to 28C, the memory unit 53 of the registration wireless tag 13 includes each product in the product group A, each product in the product group B, and each product in the product group C. Also, all product weight values are set.
Other configurations are the same as those of the first embodiment.

In such a configuration, the product weight value together with the product identification code is received from the wireless tag 13 by making an inquiry to the wireless tag 13 attached to the product 3 from the wireless tag reader 7 of the registration settlement apparatus 9 for all products. Then, the sum total value of the received product weight values is compared with the weight value measured by the weigh scale 6.
In this embodiment, the same operational effects as those of the first embodiment described above can be obtained.

(Third embodiment)
This uses a label that is used only for the purpose of attaching the registration wireless tag 13 to a product instead of the display label 14 that forms a pre-printing section for printing product information such as a store name, product name, unit price, and weight. It is.
That is, as shown in FIG. 29, this label 71 is formed by connecting a pair of special comb-shaped conductive patterns 71b1 and 71b2 to each other by a thick film printing process on a base paper 71a and each comb-shaped conductive pattern 71b1. , 71b2 is provided with a perforated cutting portion 71c. A first adhesive layer (shaded portion in the figure) 71d is provided so as to cover each of the comb-shaped conductive patterns 71b1, 71b2 and the cut portion 71c. A second adhesive layer 71e is provided on the entire back surface of the base paper 71a, and the base paper 71a is pasted on the base paper 72 having both surfaces coated with silicone via the second adhesive layer 71e.

  Also in this embodiment, the mount 72 has a belt-like shape, and a large number of the labels 71 are pasted on the mount 72 as shown in FIG. And loaded as a label supply roll. As shown in FIG. 31, a display label 74 on which product information such as a store name, a product name, a unit price, and a weight is printed is attached to the product 3 together with the wireless tag with label 73.

Other configurations are the same as those of the first embodiment.
In this way, even if a label only for the purpose of attaching the wireless tag 13 to the product is used instead of the display label on which the product information such as the store name, product name, unit price, and weight is printed, the same as in the first embodiment described above. Thus, the following effects can be obtained.

(Fourth embodiment)
In this example, a registration wireless tag in which a conductive dummy pattern is connected to a comb-shaped conductive pattern is used as the registration wireless tag 13, and other configurations are the same as those in the first embodiment.
That is, as shown in FIG. 32, dummy patterns 13h1 and 13h2 are formed outside the pair of conductive patterns 13g1 and 13g2. Specifically, as shown in FIG. 33, dummy patterns 13h1 and 13h2 respectively connected to the conductive patterns 13g1 and 13g2 are formed outside a special pair of comb-shaped conductive patterns 13g1 and 13g2.

  In such a configuration, since it is difficult to accurately match the comb-shaped conductive patterns 14d1 and 14d2 of the display label 14 with the comb-shaped conductive patterns 13g1 and 13g2 of the registration wireless tag 13, the comb-shaped conductive pattern of the display label 14 is used. If a fraudulent act such as attaching a conductor film to the entire region where the patterns 14d1 and 14d2 are located is performed, the comb-shaped conductive patterns 13g1 and 13g2 of the wireless tag 13 face the conductor film, so the comb-shaped conductive pattern of the display label 14 14d1 and 14d2 coincide with each other and are in the same state. However, at this time, the dummy patterns 13h1 and 13h2 are also opposed to the conductor film.

  Originally, when the comb-shaped conductive patterns 13g1 and 13g2 of the wireless tag 13 are overlapped with the comb-shaped conductive patterns 14d1 and 14d2 of the display label 14, there is no conductive pattern opposite to the dummy patterns 13h1 and 13h2. That is, the dummy patterns 13h1 and 13h2 do not contribute to the capacity. However, when the conductor film is intentionally applied, the dummy patterns 13h1 and 13h2 also face the conductor film and contribute to the capacity.

For this reason, the capacity of the capacitor C3 in the circuit shown in FIG. 20 is significantly increased from the original capacity. Therefore, the oscillation frequency of the VCO 572 exceeds the control range, so that the PLL is out of the lock range, and the wireless tag 13 does not respond to the electromagnetic wave instructing reading from the wireless tag reader 7.
As described above, even if an illegal act is performed in which the conductive film is pasted on the entire portion of the display label 14 where the comb-shaped conductive patterns 14d1 and 14d2 are located by providing the dummy patterns 13h1 and 13h2, the display label is pasted. As a result, the mismatch of the weight values is detected by checking the total weight value. This makes it possible to know that there has been an illegal act.
