Then, when the operator of the digital multi-function peripheral 1 operates the operation panel 10 of the image reading apparatus 2, the print paper size, scaling ratio, and the like are input and set. Thereafter, by operating the operation panel 10, the start of copying is instructed.

  In response to these operations, in the image reading apparatus 2, each document on the document set tray 11 is pulled out one by one by the pickup roller 13, and the document is transferred to the platen glass 16 through the gap plate 14 and the conveyance roller 15. Then, the document is transported in the sub-scanning direction on the platen glass 16 and discharged to the document discharge tray 17.

  At this time, the first reading unit 21 reads the surface (lower side) of the document. That is, the first reading unit 21 moves and positions the first scanning unit 23 of the first reading unit 21 to a position, and positions the second scanning unit 24 at a predetermined position. The exposure lamp irradiates the surface of the document through the platen glass 16, and the reflected light of the document is guided to the imaging lens 26 by the reflection mirrors of the first and second traveling units 23 and 24, and the reflected light of the document is emitted. The image is condensed on a CCD (Charge Coupled Device) 27 by an imaging lens 26, and an image on the surface of the document is formed on the CCD 27, thereby reading the image on the surface of the document.

  Further, the second reading unit 22 reads the back surface (upper side surface) of the document. The second reading unit 22 is disposed above the platen glass 16. The second reading unit 22 includes an exposure lamp (LED (Light Emitting Diode) array, fluorescent lamp, etc.) that irradiates the back side of the document, a Selfoc lens array that collects reflected light of the document for each pixel, and A contact image sensor (CIS) that photoelectrically converts reflected light of the original received through the SELFOC lens array and outputs an analog image signal is provided.

  Next, as a method of setting a document on the image reading device 2, in a method of opening the upper housing of the image reading device 2 and placing the document on the platen glass 16, the upper housing of the image reading device 2. Is opened, the original is placed on the platen glass 16 with the reading surface facing downward, and the first reading unit 21 reads the surface of the original in this state. In this case, the first and second scanning units 23 and 24 are moved in the sub-scanning direction while maintaining a predetermined speed relationship with each other, the original on the platen glass 16 is exposed by the first scanning unit 23, and the first The second scanning units 23 and 24 guide the reflected light from the document to the imaging lens 26, and the imaging lens 26 forms an image of the document on the CCD 27.

  Thus, when one or both sides of the document are read, image data indicating an image on one or both sides of the document is input to the storage unit 8 (shown in FIG. 4), where the CPU 9 (shown in FIG. 4) Various types of image processing are performed on the image data, and the image data is output to the image forming unit 3.

  The image forming unit 3 prints an image of a document indicated by image data on a recording sheet.

  The operations of the image reading device 2, the image forming unit 3, the paper feeding unit 4, and the paper discharge processing device 5 are as described above, and these operations are performed by the CPU 9 by the OS and various processing programs described above. Control based on software.

  Next, the image reading device 2 provided in the digital multifunction device 1 will be described in detail. The image reading unit, individual front image data forming unit, individual back image data forming unit, and front / back image data association unit described above control the above-described mechanism constituting the image reading device 2 and the image reading device 2. This is realized by using hardware such as the OS and software such as the OS and various processing programs described above.

  The image reading apparatus 2 has the above-described multi-crop scan function. The multi-crop scanning function collectively reads images described in a plurality of originals such as a plurality of nouns and postcards placed side by side on the platen glass 16 provided in the image reading apparatus 2. This is a function for forming independent image data for each document.

  Therefore, when using the multi-crop scan function provided in the image reading apparatus 2, as a method of setting the original on the image reading apparatus 2, the upper casing of the image reading apparatus 2 described above is opened and the original is placed on the platen glass 16. Use the method of placing on top.

  The operation of the image reading apparatus 2 is characterized in that it can read images of a plurality of nouns and postcards on which images are written on the front and back sides and associate the read front and back images for each document.

  Therefore, the operation of the image reading apparatus 2 having this feature will be described next. In this description of the operation, four cards, card A to card D, which are small cards of the same size, such as a business card or a postcard shown in FIG. Further, the image reading apparatus 2 is assumed to have the normal mode for performing the normal reading described above and the multi-crop mode as the image reading mode.

  FIG. 6 and FIG. 7 are flowcharts showing processing by the operation of the image reading apparatus 2 having the above characteristics, that is, the operation in the multi-crop mode. First, the operator of the image reading apparatus 2 operates the operation unit 10a of the operation panel 10 of the digital multifunction device 1 to set the multi-crop mode. When the setting of the multi-crop mode is completed, the operator places a plurality of documents on the platen glass 16 of the image reading device 2. Then, it instructs the image reading device 2 to read the front image of the document.

  In the above example, all four cards A to D shown in FIG. 5 are placed on the platen glass 16 of the image reading apparatus 2 with the front of the card facing down, that is, as shown in FIG. Place the card face up. Then, the start button of the operation unit 10a of the operation panel 10 is pressed.

  Then, in FIG. 6 and FIG. 7, the CPU 9 that controls the image reading apparatus 2 first checks whether or not the multi-crop mode is set (S1), and is set to the multi-crop mode. (S2), the process proceeds to S3.

  In S3, it is checked whether or not there is an instruction to read the front image of the document. Specifically, it is checked whether or not the start button of the operation unit 10a of the operation panel 10 has been pressed. When there is an instruction to read the front image of the original (S4), the CPU 9 instructs the image reading apparatus 2 to read the front images of the plurality of originals at the same time, and reads the front image of the plurality of originals. Whole table image data including a plurality of document table images is formed on the memory of one storage unit 8 (S5).

  Then, the entire table image data is analyzed, and one document image is cut out from the entire table image data including the table images of a plurality of documents as one independent individual table image data. Then, it is formed on the memory of the storage unit 8 of the digital multi-function peripheral 1 (S6). At this time, the area information corresponding to the area on the platen glass 16 occupied by the document corresponding to the independent individual table image data is added to the independent individual table image data (S6).

  In S6, the method of forming independent individual table image data for each document from the entire table image data by analyzing the entire table image data including the table images of a plurality of documents realizes a multi-crop scan function. It can be realized by using a known technique known as a technique to do.

  As this technique, for example, a document image clipping method described in JP-A-2002-10059 (image processing apparatus) can be used. Further, according to the method described in the above publication, when a document is placed on the platen glass 16 with an inclination, individual table image data with the inclination corrected can be formed.

  When the process of analyzing the entire table image data and forming one individual table image data in S6 is completed, it is next checked whether or not the formation of individual table image data for all the originals has been completed (S7). If not completed (S8), the process returns to S6, and the processes after S6 are repeated. When completed (S8), all the processes for forming individual table image data independent for each document from the entire table image data by analyzing the entire table image data including the table images of a plurality of documents are completed. become.

  As the above-described processing for forming individual table image data independent for each original from the entire table image data, for example, in the above example, the table images of four cards A to D are read in a lump. One whole table image data is formed. By analyzing the entire table image data, independent individual table image data is formed for each of the cards A to D. Then, the area information of the card A is added to the individual table image data of the card A in the individual table image data, for example, the individual table image data of the card A.

  Further, the area information includes, for example, position information and size information. The size information is, for example, information on the size of the document obtained by the above analysis, and the position information is, for example, the central coordinate value of the size of the document that is also the information obtained by the above analysis, that is, the document occupies. The center coordinate value of the size indicated by the size information in the area on the platen glass 16 is used.

  If the formation of the individual table image data for all the originals in the check in S7 is completed (S8), the process proceeds to S9. In S <b> 9, an instruction to turn over the original is displayed on the display unit 10 b of the operation panel 10 of the digital multifunction device 1. Then, the process proceeds to S10.

  By displaying the instruction for turning over the original on the display unit 10b in S9, the operator of the image reading device 2 places the cards A to C placed on the platen glass 16 of the image reading device 2 as shown in FIG. All four cards of D are turned over so that the back side of the card faces downward, that is, as shown in FIG. Then, the start button of the operation unit 10a of the operation panel 10 is pressed.

  Then, in S10, it is checked whether or not there is an instruction to read the back image of the document. Specifically, it is checked whether or not the start button of the operation unit 10a of the operation panel 10 has been pressed. In S10, when there is an instruction to read the back image of the document (S11), the CPU 9 instructs the image reading apparatus 2 to collectively read the back images of the plurality of documents and reads the back images of the plurality of documents. Then, the entire back image data including the back images of a plurality of documents is formed on the memory of the storage unit 8 of the digital multi-function peripheral 1 (S12), and the process proceeds to S13.

  In S13, the entire back image data is analyzed based on the area information added to one already formed individual front image data, so that the individual back image data is stored in the storage unit 8 of the digital multi-function peripheral 1. It is formed on the memory (S13).

  In S13, the individual back image data is formed by analyzing the entire back image data including the back images of the plurality of documents based on the area information added to the already formed individual table image data. The method can be realized by using a known technique known as a technique for realizing the multi-crop scan function, as in the above-described formation of individual table image data.

  When the formation of the individual back image data in S13 is completed, the formed individual back image data and the individual table image data to which the area information used for forming the individual back image data is added are integrated. Then, one file data is formed, and the process proceeds to S15.

  In S15, it is checked whether or not the formation of the individual back image data and the integrated file data for all the originals is completed (S15). If not completed (S16), the process returns to S13, and after S13. Repeat the process. If completed (S16), since all the processes are completed, the process in the multi-crop mode of the image reading apparatus 2 is terminated.

  The above-described individual back image data is formed for each original from the entire back image data including the back images of a plurality of originals, and the individual back image data and the individual front image data are integrated to form one file data. As the process to be formed, for example, in the above example, first, the back images of the four cards A to D are collectively read to form one whole back image data.

  Then, based on the area information added to the individual table image data that has already been formed for each of the four cards A to D, the entire back image data is determined. The individual back image data is cut out from the image data. For example, by analyzing the entire back image data including the back images of the four cards A to D based on the area information added to the individual front image data already formed on the card A, The individual back image data of the card A is cut out from the entire back image data.

  Then, for example, the individual back image data of the card A and the individual front image data of the card A are integrated to form one file data. Similarly, one file data is formed for the cards B to D. FIG. 10 shows files 1 to 4 formed in this way.

  According to the processing in the multi-crop mode of the image reading apparatus 2 described above, the front image and the back image are collectively read with respect to a plurality of originals such as nouns and postcards on which the images are described on the front and back sides. Thus, the entire front image data and the entire back image data which are the entire image data are formed. Then, individual front image data and individual back image data, which are individual image data independent for each original, are formed from the entire front image data and the entire back image data. Further, the individual table image data and the individual back image data can be integrated to form a single file data, and can be associated for each document.

  Therefore, it is possible to read a plurality of originals such as business cards with images on the front and back at a time, and by associating the front and back images of the original with the images on the front and back. These images can be stored and displayed as a unit.

  In the above-described processing in the multi-crop mode of the image reading apparatus 2, the individual front image data and the individual back image data are associated with each other, and the individual front image data and the individual back image data are integrated to form one file data. It is done by doing. However, the method of associating the individual front image data and the individual back image data is not limited to this. For example, the individual front image data and the individual back image data are set as separate files and are used for front and back management. Data may be provided, and identification information such as the name and address of each file may be recorded in the front / back management data.

  Further, in the processing in the multi-crop mode of the image reading apparatus 2 described above, after the multi-crop mode setting operation by the operator of the image reading apparatus 2, the operator of the image reading apparatus 2 makes a plurality of document sizes of the same size. May be input by operating the operation unit 10a of the operation panel 10 of the digital multi-function peripheral 1.

  In this case, in S6 of the flowchart shown in FIG. 6, the size input above is used as the size for cutting out the individual table image data from the entire table image data including the table images of a plurality of documents. The size input above is used as the size in the size information of the area information added to the individual table image data.

  Therefore, in S13 of the flowchart shown in FIG. 7, the area information that is the size input above is used as the size when one individual back image data is cut out from the entire back image data including the back images of a plurality of documents. The size in the size information is used.

  By doing in this way, the process in the process in the multi crop mode of the image reading apparatus 2 can be simplified.
