Abstract

When data received from a scanner is barcode data with an add-on barcode but the add-on barcode data is not read, an error is generated when the data is received.
When barcode data is received from a barcode scanner, whether the barcode data is a main barcode including a product identification code or a barcode obtained by adding an add-on barcode to the main barcode. It is identified by data of a predetermined digit of the code. When the barcode data is identified as a barcode obtained by adding an add-on barcode to the main barcode, it is determined whether or not the barcode data includes an add-on barcode. If it is determined that the barcode is not included, an error occurs.

Description

  The present invention relates to a POS (Point Of Sales) terminal, electronic cash, which is connected to a scanner for reading a barcode attached to a product and processes product sales data based on the barcode data read by the scanner. The present invention relates to a merchandise sales data processing apparatus such as a register.

  In order to maintain consistency with the JAN code system established as a unified product code so far, barcodes attached to periodicals such as magazines in Japan are published in a two-digit periodical code flag. Consists of a 13-digit bar code that includes a 7-digit publication code that indicates the issue type, type, number of items, etc., a 3-digit price code that indicates the price of the publication, and a 1-digit check digit It had been. In the bar code for this periodicals, the price was the sales price including consumption tax. For this reason, in a merchandise sales data processing device that reads this type of bar code with a scanner and performs processing such as sales registration of merchandise sales data based on the bar code data, it uses the read bar code flag for periodic publications. When it is recognized that the barcode is, the price data is acquired from the barcode, and the price data is displayed as it is as the price of the product (magazine or the like) to which the barcode is attached.

  However, considering that magazines may be sold after being stored as back numbers for a long period of time, and the tax rate may change during that time, the price included in the barcode is less tax than the price including tax. The price was better. Therefore, this time, the barcode system of the periodicals is changed to a 13-digit main barcode (periodical publication code flag [491] according to the standard of JAN code (13-digit barcode with the first two digits “49”). ], And an 18-digit bar code with a 5-digit add-on bar code added, and the tax-excluded price will be represented by 4 digits in the add-on bar code.

  In general, the barcode is read by an optical scanner. The scanner irradiates and scans the bar code with beam light such as laser light and LED light, and receives and reads the reflected light. That is, the scanner photoelectrically converts the received reflected light, converts this photoelectric conversion output into a digital signal by a binarization circuit, and then decodes (demodulates) it into characters such as alphanumeric characters by a decoding circuit.

In this type of scanner, the first three digits of the decoded main bar code are checked to determine whether the bar code is accompanied by an add-on bar code. Bar code data is not allowed to be transferred to the merchandise sales data processing device until the code is decoded, and only the main bar code data is transferred to the merchandise sales data processing device if the bar code does not have an add-on bar code Such a scanner has already been proposed (see, for example, Patent Document 1).
JP-A-8-329175

  However, a general scanner in practical use at this time checks whether or not an add-on barcode is decoded when the main barcode data is read normally, and if the add-on barcode is decoded. Transfer both the main barcode and add-on barcode data to the merchandise sales data processing device. If the add-on barcode is not decoded, the add-on barcode is regarded as not added and the main barcode data is regarded as the merchandise sales data. The data was transferred to a processing device. For this reason, only the main bar code data is transferred to the merchandise sales data processing apparatus even though the add-on bar code is attached. In this case, the merchandise sales data processing apparatus receives the data from the scanner. The merchandise sales data processing is started based on the bar code data. In practice, however, this bar code data is accompanied by add-on bar code data and has a single meaning. Therefore, the merchandise sales data cannot be processed and an error occurs or incorrect data processing is performed. There was a fear.

  The present invention has been made based on such circumstances, and the object of the present invention is to add the add-on barcode data even though the data received from the scanner is the barcode data with the add-on barcode. If not, an object of the present invention is to provide a merchandise sales data processing apparatus which can be regarded as an error when the data is received and which can improve processing efficiency and reliability.

  The present invention relates to a product sales data processing apparatus that is connected to a bar code scanner and processes sales data of a product to which the bar code is attached based on the bar code data read by the bar code scanner. When the barcode data is received from the code scanner, whether the barcode data is a main barcode including a product identification code or a barcode obtained by adding an add-on barcode to the main barcode, a predetermined digit of the main barcode, For example, it is identified by the first three digits of data. When the barcode data is identified as a barcode obtained by adding an add-on barcode to the main barcode, it is determined whether or not the barcode data includes an add-on barcode. If it is determined that the barcode is not included, an error is generated.

  According to the present invention in which such a measure is taken, when the data received from the scanner is barcode data with an add-on barcode but the add-on barcode data is not added, the data is received. It is possible to provide a merchandise sales data processing apparatus that can generate an error at a point in time and improve processing efficiency and reliability.

The best mode for carrying out the present invention will be described below with reference to the drawings.
This embodiment is a case where the present invention is applied to a POS terminal 20 capable of processing a bar code for a new-periodical publication (hereinafter referred to as a new magazine barcode 10 for convenience of explanation).

  As shown in FIG. 1, the new magazine barcode 10 is composed of a total 18-digit barcode in which a 5-digit add-on barcode 12 is added to the right side of a 13-digit main barcode 11 according to the JAN code standard. Of the main bar code 11, the first three digits are a periodicity code flag 13, which is fixed at [491]. The remaining 10 digits are the product identification code 14, and the breakdown is as follows: the first digit is a spare code (magazine = 0), the second to sixth digits are item codes, the seventh and eighth digits are the month or number, and the ninth digit Is the year and the 10th digit is the check digit. In addition, among the add-on barcodes 12, the first digit is a spare code, and the remaining four digits are a price code 15. The price code 15 is a main unit price excluding tax in units of yen.

  FIG. 2 is a perspective view showing an external configuration of the POS terminal 20 in the present embodiment. The POS terminal 20 is provided with a keyboard 21, a mode switch 22 and an operator display 23 on the front of the main body, and a customer display 24 on the back. In addition, a printer 25 for printing a receipt is built in the terminal body, and a receipt printed by the printer 25 is discharged from a receipt issuing port 26. The POS terminal 20 is connected to a scanner 27 for optically reading a barcode. In addition, a drawer 28 for storing change or the like is formed integrally with the POS terminal 20.

  The scanner 27 checks whether or not the add-on bar code is decoded when the main bar code data conforming to the 13-digit JAN code system is normally read. If the add-on bar code is decoded, the scanner 27 Both the code and add-on barcode data are transferred to the POS terminal 20. If the add-on barcode is not decoded, only the main barcode data is transferred to the POS terminal 20.

  FIG. 3 is a block diagram showing a main configuration of the POS terminal 20. The POS terminal is provided with a CPU (Central Processing Unit) 31 as a control unit main body. Also, a ROM (Read Only Memory) 32 in which fixed data such as a program is stored in advance, a RAM (Random Access Memory) 33 in which various memory areas for storing rewritable data are rewritable, a current date Data communication between the clock unit 34 for measuring time and the store computer 50 that manages the product file 51 in which product information such as product name and price of the product is set in advance corresponding to the product identification code for each product. A communication interface 35 for controlling the scanner, a scanner interface 36 to which barcode data read by the scanner 27 is input, a mode selection signal from the mode switch 22 and an open command signal to the drawer 28 are output. A keyboard controller 38 for capturing key signals corresponding to operation keys from the port 37 and the keyboard 21; A display controller 39 that displays an image corresponding to display data on the display 23 for the operator, a display controller 40 that displays an image corresponding to the display data on the customer display 24, a printer controller 41 that controls the printing operation of the printer 25, etc. Is provided. The CPU 31, ROM 32, RAM 33, clock unit 34, communication interface 35, scanner interface 36, I / O port 37, and controllers 38 to 41 of various input / output devices are connected by a bus line 42 such as an address bus and a data bus. ing.

  In addition to the numeric keys “0” to “9”, the keyboard 21 is provided with various function keys such as an amount key, a total key, a current key, and a clear key. The money amount key is a key for declaring that the numeric data is money data. The total key is a key for instructing the total output of one transaction. The current total key is a key for declaring that the numeric data is cash payment amount data. The clear key is a key for instructing clearing of a numerical value and cancellation of an error state.

  The mode switch 22 is an operation switch for instructing the CPU 31 to execute a business mode selected and operated from various business modes such as “registration”, “inspection”, and “settlement”. Incidentally, “registration” refers to the process of registering the sales data of the product with the barcode attached to the predetermined memory area of the RAM 33 based on the barcode data read by the scanner 27 and issuing a receipt for each transaction. It is a mode of business that performs etc. “Inspection” is a task of totaling data registered in a predetermined memory area by a “registration” task for each tabulation item, creating sales data for each tabulation item, and printing or displaying the data. “Settlement” is a task of clearing data registered in a predetermined memory area after creating and outputting sales data for each tabulation item as in “inspection”.

  In the RAM 33, the bar code data received from the scanner 27 and the tax rate memory 61 in which the current tax rate of the tax (consumption tax) is set, as shown in FIG. A barcode buffer 62 for temporarily storing, a receipt buffer 63 for temporarily storing receipt print data for one transaction, and an amount totalizer 64 for totaling the amount of merchandise purchased for one transaction are formed.

  Accordingly, when the CPU 31 receives the barcode data read by the scanner 27 via the scanner interface 36 in the “registration” mode, the CPU 31 starts the barcode input processing shown in the flowchart of FIG.

  First, the CPU 31 stores the barcode data received from the scanner 27 as ST (step) 1 in the barcode buffer 62. Next, the CPU 31 checks the first two digits of the barcode data in the barcode buffer 62 as ST2, and determines whether or not it conforms to the JAN code standard starting with "49". If the first two digits do not start with “49”, barcode data that does not conform to the JAN code standard has been input, and processing corresponding to the barcode data is executed.

  When the first two digits start with “49”, the CPU 31 determines whether the third digit from the beginning is “1” as ST3, that is, the new magazine barcode 10 whose first three digits begin with “491”. (Bar code identifying means). If the third digit from the beginning is not “1”, the barcode data stored in the barcode buffer 62 is recognized as corresponding to the JAN code instead of the new magazine barcode 10, and the normal data Execute PLU processing.

  That is, the store computer 50 is inquired with the product identification code included in the 13-digit barcode data stored in the barcode buffer 62. When the product information such as the product name and price set in the product file 51 corresponding to the product identification code is called up, the product name and price are displayed on the operator display 23 and the customer display 24. Let Further, the product name and price data are stored in the receipt buffer 63. Further, the price is added to the data of the money totalizer 64. It is assumed that a tax-included price is set in advance in the product file 51 for the taxable product.

  If the first digit of the barcode data is “491”, it is recognized that the barcode data stored in the barcode buffer 62 is that of the new magazine barcode 10. Then, it is determined whether the add-on barcode 12 is included in the barcode data stored in the barcode buffer 62 as ST4 (barcode data determination means).

  Here, when it is confirmed that the barcode data is composed of the 13-digit main barcode 11 and the 5-digit add-on barcode 12, the new magazine barcode 10 is normally read by the scanner 27. Performs the following processing.

  First, the product identification code 14 is acquired from the data of the main barcode 11 stored in the barcode buffer 62 as ST5. Further, the price code 15 is acquired from the data of the add-on barcode 12 (price acquisition means). Next, the store computer 50 is inquired with the product identification code 14 acquired as ST6. Then, the product name set in the product file 51 corresponding to the product identification code is called. Next, the price code 15 acquired in ST7 is set as the main unit price A, and the tax-included price C of the registered product is calculated from the main unit price A and the tax rate B set in the tax rate memory 61 by the following equation (1) ( Tax-included price calculation means).

C = A + A × B (1)
Then, as ST8, this tax-included price C is displayed on the operator display 23 and the customer display 24 together with the product name of the registered product (product price display means). In ST9, the product name and the price C including tax are stored in the receipt buffer 63. Further, in ST10, the price including tax C is added to the data of the money totalizer 54. Thereafter, if the barcode data in the barcode buffer 62 is cleared in ST11, the current barcode input process is terminated.

  If it is confirmed in ST4 that the barcode data stored in the barcode buffer 62 does not include the add-on barcode 12, the CPU 31 makes a barcode reading error in ST12. Then, a message indicating a reading error, for example, “Bar code was not read correctly” is displayed on the operator display 23 to warn the operator (error notification means). Thereafter, if the clear key is operated in ST13, an error cancellation command has been issued, so the CPU 31 clears the barcode data in the receipt buffer 63 in ST14 and ends the current barcode input processing (read error processing). means).

  Thus, in the POS terminal 20 of the present embodiment, when the first three digits of the 13-digit barcode data corresponding to the main barcode 11 among the barcode data received from the scanner 27 is “491”, It is recognized as a reading of a new magazine barcode 10 having an add-on barcode 12. Then, it is checked whether or not the barcode data received from the scanner 27 includes barcode data corresponding to the add-on barcode 12, and if the barcode data is not included, an error occurs in reading the barcode. To that effect.

  Even though the operator reads the new magazine barcode 10 printed on the magazine with the scanner 27, the scanner 27 recognizes only the main barcode 11, so only the decoded data of the main barcode 11 is sent to the POS terminal 20. It may not be given. In such a case, an inquiry is made to the store computer 50 at the conventional POS terminal and an error occurs because the corresponding product identification code is not set in the product file 51, or wrong product information is called from the product file 51. Incorrect data processing has been executed.

  On the other hand, in the POS terminal 20 of the present embodiment, a barcode reading error occurs immediately, and no inquiry is made to the store computer 50. Therefore, it is possible to save useless time required for the inquiry, thereby improving processing efficiency. In addition, since the merchandise sales data is not illegally processed, the reliability can be improved.

  By the way, in Japan, when displaying prices on price tags, advertisements, etc. for consumers, a total amount display method that requires display of total payment amounts including consumption tax equivalents has started. For this reason, when the new magazine barcode 10 is read by a conventional POS terminal, the price included in the add-on barcode is a tax-excluded price, so the amount displayed as the price of the periodicals is the tax-excluded price, There arises a problem that it is not suitable for the total amount display method.

  On the other hand, when the POS terminal 20 of the present embodiment recognizes the barcode data of the add-on barcode 12 following the main barcode 11, the POS terminal 20 acquires the tax-excluded body price included in the add-on barcode 12 In addition, since it is converted into a price including tax and displayed, the total amount display method can be supported.

  In the above embodiment, the new magazine barcode 10 is exemplified as the barcode to which the add-on barcode is added, but the type of barcode is not particularly limited. The present invention can be applied to any barcode that can recognize that an add-on barcode is added from data of a predetermined digit of the main barcode.
