  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the present embodiment, the paper is expressed as a continuous paper, and the formation of an image on the paper may be expressed as printing.

  FIG. 1 is a diagram showing an image forming system 10 according to the present embodiment. The image forming system 10 includes an image forming apparatus 12 and a cutting device 20 that cuts the continuous paper on which an image is formed by the image forming apparatus 12. As shown in the figure, the continuous paper 18 is first formed with an image by the image forming unit 16, then conveyed to the cutting device 20, and cut by the cutting device 20 to become a cut paper. In conventional continuous paper, cutting can be performed only for each page. However, in variable printing, pages can be cut into several pages, and various types of cutting can be performed regardless of the pages.

  The image forming apparatus 12 includes a print server 14, an image formation control unit 15, and an image formation unit 16. The print server 14 and the image formation control unit 15 execute a function by a CPU (Central Processing Unit) (not shown), a RAM (Random Access Memory) that stores information, a ROM (Read Only Memory), an HDD (Hard). Disk Drive) etc.

  The image forming unit 16 forms an image on continuous paper, and is a so-called tandem type image forming unit in FIG. Tandem type structural features are that a plurality of units that form toner images of different colors, such as yellow, magenta, cyan, and black, are placed on the outer peripheral surface side of an intermediate transfer member such as an intermediate transfer belt. It is located along the direction of rotation.

Color image formation by such a tandem image forming unit 16 corresponds to the formed color toner image of yellow, magenta, cyan, black, etc., with the original color image information on the outer peripheral surface of the intermediate transfer member. The toner images (color toner images) thus superposed are transferred onto the surface of the continuous paper conveyed by an unillustrated conveying means from the intermediate transfer member, and then secondary-transferred collectively. This is done by fixing the toner image on the surface of the continuous paper.

  In addition, the black and white image is formed in the same manner as the color image, except that the toner image is not superimposed on the outer peripheral surface of the intermediate transfer body after the black toner is formed. This is done by fixing.

  The image information indicating the image to be printed and the cut information indicating the cutting position of the printed paper are acquired from, for example, a PC (Personal Computer) connected to the print server 14 or the HDD of the print server 14.

  The print server 14 is provided with a function of converting the acquired cut information into a two-dimensional code. However, the image forming control unit 15 may be provided with the function.

  The image formation control unit 15 includes an image indicated by the acquired image information, a timing mark indicating a timing at which the code sensor 24 that reads the two-dimensional code provided in the cutting device 20 while conveying the continuous paper, reads the two-dimensional code, The image forming unit 16 is controlled so as to form a two-dimensional code converted from the cut information on the continuous paper.

  On the other hand, the cutting device 20 includes a cutting control unit 30, a timing sensor 22, a code sensor 24, a conveyance roller 28, and a cutting unit 26.

  Among these, the code sensor 24 reads the two-dimensional code indicating the cut information from the paper being transported by the transport roller 28, and for example, a CCD camera or the like can be used.

  The timing sensor 22 reads a timing mark indicating the timing at which the code sensor 24 reads the two-dimensional code from the paper being transported by the transport roller 28. For example, the timing sensor 22 uses reflected light of light irradiated on the continuous paper. It may be detected.

  The cutting unit 26 cuts the continuous paper with a cutter based on the cut information, and for example, a cutter using laser light is used as the cutter.

  The cutting control unit 30 has a function of converting a two-dimensional code into cut information. Then, when the timing mark is read by the timing sensor 22, the cutting control unit 30 controls the code sensor 24 to read the two-dimensional code, and cut information converted from the two-dimensional code read by the code sensor 24. Based on the above, the cutting unit 26 is controlled to cut the continuous paper.

  Next, the two-dimensional code will be described with reference to FIG. FIG. 2A shows a cutting line (shown by a dotted line) indicating a position where the continuous paper is cut, a timing mark, and a two-dimensional code. The XY coordinates are also shown in the figure, but are shown for explanation and are not actually printed.

  As shown in the figure, the timing mark and the two-dimensional code are printed outside the image printing range (end). In addition, the timing mark is read first, and then the two-dimensional code is read. The reading time of the two-dimensional code is determined by the position of the two-dimensional code when the timing mark is read, the position where the code sensor 24 can read the two-dimensional code, and the conveyance speed.

  FIG. 2B shows an actual two-dimensional code, and this two-dimensional code is converted from the cut information shown in FIG. The cut information shown in FIG. 2C will be described with reference to FIG.

  First, the first line indicates that the X coordinate (100) cuts the entire Y direction (corresponding to A in FIG. 2A). The second line indicates that the X coordinate (600) cuts all of the Y direction (corresponding to B in FIG. 2A). The third line shows that (850,1000) is cut from the coordinates (850,400) (corresponding to C in FIG. 2A).

  The fourth line indicates that the X coordinate (1200) cuts all of the Y direction (corresponding to D in FIG. 2A). The fifth line indicates that the coordinates (100,0) to (1200,0) are cut (corresponding to E in FIG. 2A). The sixth line shows that (1200,400) is cut from the coordinates (600,400) (corresponding to F in FIG. 2A). The seventh line indicates that (1200,750) is cut from the coordinates (850,750) (corresponding to G in FIG. 2A).

  Next, examples of a two-dimensional code, a timing mark, and a cutting position will be described. FIG. 3 shows a continuous paper for cutting one page into several. The cutting position of the first page is indicated by a cutting line A, and the cutting position of the first page is indicated by a cutting line B. A two-dimensional code and a timing mark are provided for each page. The two-dimensional code A indicates cut information on the first page, and the two-dimensional code B indicates cut information on the second page. These two-dimensional codes are read by the code sensor 24 when the timing mark provided immediately before the two-dimensional code is read by the timing sensor 22.

  A printing process (part 1) executed by the image forming apparatus 12 when printing continuous paper as shown in FIG. 3 will be described with reference to the flowchart of FIG. First, in step 101, a timing mark is printed, and in step 102, image information and cut information are acquired. Next, in step 103, the cut information is converted into a two-dimensional code, and in the next step 104, the two-dimensional code is printed. If it is determined in step 105 that all printing has not been completed, the process returns to step 101. Return to processing. On the other hand, if it is determined that all printing has been completed, the process ends. Note that an image is printed in parallel with this printing process.

  Next, a cutting process (part 1) executed by the cutting device 20 when cutting continuous paper as shown in FIG. 3 will be described with reference to the flowchart of FIG.

  First, when a timing mark is read in step 201, a two-dimensional code is read in step 202. In the next step 203, the two-dimensional code is converted into cut information. In step 204, the continuous paper is cut based on the cut information. The processing returns to step 201. On the other hand, if it is determined that all the cuts have been completed, the process ends.

  This flowchart shows only the processing executed for one page, and the processing in steps 201, 202, and 203 and the processing in step 204 are performed in parallel.

  The above flowchart shows the processing when there is no failure in reading the two-dimensional code, but when the reading fails, the cutting processing is interrupted. Further, the failure of reading can be recognized by reading the timing mark almost certainly and then failing to read the two-dimensional code.

  Next, FIG. 6 shows a plurality of two-dimensional codes indicating the same cut information so that the code sensor 24 can read the two-dimensional code indicating the same cut information a plurality of times during conveyance of the continuous paper. It is a figure which shows the continuous paper arranged in the conveyance direction.

  As shown in the figure, a plurality (three in the figure) of two-dimensional codes A and a plurality (three in the figure) of two-dimensional codes B are arranged in the transport direction.

  When the code sensor 24 fails to read the two-dimensional code, the cutting control unit 30 controls the code sensor 24 to read again the same two-dimensional code as the two-dimensional code that has failed to be read. For example, if reading of the first two-dimensional code fails, control is performed so that the second two-dimensional code is read next.

  A printing process (part 2) executed by the image forming apparatus 12 when printing continuous paper as shown in FIG. 6 will be described with reference to the flowchart of FIG. First, in step 301, a timing mark is printed, and in step 302, image information and cut information are acquired. Next, in step 303, the cut information is converted into a two-dimensional code. In the next step 304, the two-dimensional code is printed a plurality of times (three times in FIG. 6), and all printing is not completed in step 305. If it is determined, the process returns to step 301 again. On the other hand, if it is determined that all printing has been completed, the process ends. Note that an image is printed in parallel with this printing process.

  Next, the cutting process (part 2) executed by the cutting device 20 when cutting continuous paper as shown in FIG. 6 will be described with reference to the flowchart of FIG. Note that the cutting device 20 in this case can acquire whether the continuous form paper as shown in FIG. 6 is set in advance or how it is printed from the image forming device 12. To do.

  First, when a timing mark is read in step 401, a two-dimensional code is read in step 402. In the next step 403, it is determined whether or not the two-dimensional code has been successfully read. If the two-dimensional code has been successfully read, the two-dimensional code is converted into cut information in step 404. If the paper is cut and it is determined in step 406 that all cutting has not been completed, the process returns to step 401 again. On the other hand, if it is determined that all the cuts have been completed, the process ends.

  On the other hand, if a negative determination is made in step 403, it is determined whether or not the number of read failures is larger than the number of two-dimensional codes printed in step 407. If a negative determination is made in step 403, there is still a readable two-dimensional code, so the process returns to step 402 again. If an affirmative determination is made, there is no readable two-dimensional code. Exit.

  This flowchart only shows the processing executed for one page, and the processing in steps 401 to 404 and the processing in step 405 are performed in parallel.

  Next, FIG. 9 is a diagram showing a continuous paper on which a plurality of two-dimensional codes are printed so that the code sensor 24 can read the two-dimensional code at a predetermined time interval during conveyance of the continuous paper. As shown in the figure, the continuous paper is printed with only one timing mark and then a two-dimensional code.

  In this case, when the timing mark is read by the timing sensor 22, the cutting control unit 30 controls the code sensor 24 to read the two-dimensional code at a predetermined time interval. Specifically, when the page mark is read, the two-dimensional code A is first read, and the two-dimensional code B is read after a predetermined time has elapsed. As shown in the figure, only one timing mark is printed.

  A print process (part 3) executed by the image forming apparatus 12 when printing continuous paper as shown in FIG. 9 will be described with reference to the flowchart of FIG. First, in step 501, a timing mark is printed, and in step 502, image information and cut information are acquired. Next, in step 503, the cut information is converted into a two-dimensional code, the two-dimensional code is printed in the next step 504, and if it is determined in step 505 that all printing has not been completed, the process returns to step 502. Return to processing. On the other hand, if it is determined that all printing has been completed, the process ends. Note that an image is printed in parallel with this printing process.

  Next, the cutting process (part 3) executed by the cutting device 20 when cutting continuous paper as shown in FIG. 9 will be described with reference to the flowchart of FIG. Note that the cutting device 20 in this case can acquire whether the continuous form paper as shown in FIG. 9 is set in advance or how it is printed from the image forming device 12. To do.

  First, when a timing mark is read in step 601, a two-dimensional code is read in step 602. In the next step 603, the two-dimensional code is converted into cut information. In step 604, the continuous paper is cut based on the cut information, and if it is determined in step 605 that all cuts have not been completed, the process again. The processing returns to step 602. On the other hand, if it is determined that all the cuts have been completed, the process ends.

  In this flowchart, only the process executed for one page is shown, and the processes in steps 602 and 603 and the process in step 604 are performed in parallel.

  As described above, when the two-dimensional code is read at a predetermined time interval, cutting can be performed regardless of the conventional page size by changing the time interval in various ways.

  Furthermore, the above-described processing can cope with a case where the cut information per page is too large to be expressed by one two-dimensional code. This is because many two-dimensional codes can be read by reducing the time interval for reading according to the amount of cut information.

  Next, detection of the shift amount will be described with reference to FIG. FIG. 12 is a diagram illustrating printed timing marks so that the amount of deviation in the direction intersecting the continuous paper transport direction in the cutting device 20 can be detected. In the description so far, the timing mark, which has been represented by the same color (black in the figure) as the whole rectangle, has a diagonal line different from the rectangular color (white in the figure) as shown in the figure.

  FIG. 12A shows the waveform of the signal read from the timing mark when no deviation occurs, and FIG. 12B shows the waveform of the signal read from the timing mark when deviation occurs. Is shown.

  When there is no deviation, the signals indicating black are equally spaced. On the other hand, when a deviation occurs, the signals indicating black are not equally spaced. As shown in FIG. 12B, when the signal indicating the first black is longer than the signal indicating the subsequent black, it can be seen in the same figure that the continuous paper is shifted upward. Is shorter than the signal indicating the subsequent black, it can be seen that the continuous paper is shifted downward.

  In addition, it is possible to detect how much is shifted by the length of the signal indicating black. When the timing marks are shifted as described above, the position of the two-dimensional code read by the code sensor 24 is naturally shifted.

  In this case, the cutting control unit 30 controls the position at which the code sensor 24 reads the two-dimensional code according to the amount of deviation detected by the timing sensor 22.

  The timing mark only needs to be capable of detecting the amount of deviation in the direction intersecting the sheet conveyance direction in the cutting apparatus, and may be other than the shape shown in FIG.

  The processing flow of each flowchart described above is an example, and the processing order may be changed, new steps may be added, or unnecessary steps may be deleted without departing from the scope of the present invention. Needless to say, you can.

  In addition, even when a multi-dimensional code or a color code is used instead of the two-dimensional code described above, it goes without saying that the present embodiment can be applied because the relationship between the code and the timing mark does not change.

  Furthermore, in the present embodiment, the continuous paper is cut immediately after printing. However, as described above, the timing mark and the two-dimensional code are printed on the continuous paper, so only printing is performed. Then, the printed continuous paper may be cut by the cutting device 20.
