Then, the CPU 30 stores the printed information in the registration information storage unit 34 in association with the document data 40 previously stored in the registration information storage unit 34. The printed information is information that records up to which data portion of the document data has been printed.

  On the other hand, in the image forming apparatus 2 that has received the print data of the document data 40 by the interface unit 17, the front identification mark 41, the rear identification mark 42, and the entry are based on the print data, as in the normal printing operation described above. The table 43 is printed at the printing position on the recording paper of the designated size. Then, an additional recording sheet that is a recording sheet on which the front identification mark 41, the rear identification mark 42, and the entry table 43 are printed is discharged to the face-down tray 142.

  As described above, a plurality of document data is registered in the registration information storage unit 34 by the personal computer 3 when the personal computer 3 is used by the user at an appropriate time.

  Next, the update of the document data stored in the registration information storage unit 34 will be described below. The description will be made by taking the document data 40 stored in the registration information storage unit 34 as an example. For example, an input unit (not shown) of a register (not shown) connected to the network 80 is used by a user to input character string data such as a registration number and the remaining number of document data 40, and then to the personal computer 3. An input for transmitting the registration number and character string data of the document data 40 is performed. When an input signal is sent from the register input unit to the register control unit (not shown) along with the input, the register control unit sends the register interface unit (not shown) to the personal computer 3. An update command for adding the character string data to the registration number and character string data of the document data 40 and the document data 40 corresponding to the registration number is transmitted. The character string data is composed of one or more character data and symbol data.

  On the other hand, in the personal computer 3, when the interface unit 35 receives the registration number, the character string data, and the update command of the document data 40 stored in the registration information storage unit 34, it is stored in the registration information storage unit 34 by the CPU 30 according to the update command. Document data 40 corresponding to the registration number received from the plurality of document data is extracted. Then, after the document setting information associated with the document data 40 is extracted by the CPU 30, the document data 40 in which the character string data is added to the entry field 43a of the document data 40 according to the document setting information is stored in the registration information storage unit. 34 is updated and stored. Further, the CPU 30 records unprinted information in which the character string data added to the entry field 43a of the document data 40 is recorded as unprinted, and print position information which is the print start position of the added character string data. Is stored in the registration information storage unit 34 in association with the document 40 stored in the registration information storage unit 34. Note that the character string data may be similarly added to the entry field 43a of the document data 40 and updated by the personal computer 3 alone.

  Further, as described above, a plurality of documents stored in the registration information storage unit 34 by the personal computer 3 or the register (not shown) or the like by using the personal computer 3 or the register (not shown) or the like by the user as appropriate. Data is updated.

  Next, the printing operation on the additional recording paper of the character string data added to the document data stored in the registration information storage unit 34 in the image forming processing system 1 of the present embodiment will be described below with reference to the drawings. I do. FIG. 7 is a flowchart for explaining the operation of the image forming apparatus 2 when character string data is printed on the additional recording paper. FIG. 8 is a flowchart for explaining the operation of the personal computer 3 when the character string data is printed on the additional recording paper. The operation of the image forming apparatus 2 of the present embodiment is described first, and then the operation of the personal computer 3 of the present embodiment is described.

  In the image forming apparatus 2 in the image forming processing system 1 of the present embodiment, an additional record in which the front identification mark 41, the rear identification mark 42, and the entry table 43 are printed on the manual feed tray 133 by the user in step S7-1. When paper is set and the operation display unit 11 is operated to select paper feed from the manual feed tray 133, an operation signal indicating that paper feed from the manual feed tray 133 is input from the operation display unit 11 to the CPU 10. Is done. Subsequently, when an additional print key (not shown) of the operation display unit 11 is pressed, the operation display unit 11 accepts the start of printing in the additional print mode for performing additional printing on the additional recording paper. When a signal for starting printing in the additional print mode is input from the operation display unit 11 to the CPU 10, additional recording paper on the manual feed tray 133 is conveyed by the manual feed roller 134 by the manual feed roller 134 under the control of the CPU 10. It is sent out toward. Then, the additional recording paper that has reached the transport roller 135 is transported toward the registration roller 137 by the transport roller 135. Note that the additional recording paper may be set in the paper feed cassette 131 and conveyed from the paper feed cassette 131.

  When the leading end portion of the additional recording paper conveyed toward the registration roller 137 is detected by the paper detection sensor 16, a detection signal is transmitted from the paper detection sensor 16 to the CPU 10. When the CPU 10 recognizes that the leading end portion of the additional recording paper has reached the installation position of the paper detection sensor 16 based on the detection signal, the printing surface sensor 15 starts reading the printing surface of the additional recording paper. A control signal to be transmitted is transmitted from the CPU 10 to the printing surface sensor 15. When the printing surface sensor 15 receives this control signal, the printing surface sensor 15 starts reading the printing surface of the additional recording paper. Then, the image data of the printing surface of the additional recording sheet generated by being read by the printing surface sensor 15 while being conveyed toward the registration roller 137 by the conveying roller 135 is transmitted from the printing surface sensor 15 to the CPU 10. The

  Subsequently, when the trailing edge portion of the additional recording sheet conveyed toward the registration roller 137 is detected by the sheet detection sensor 16, a detection signal is transmitted from the sheet detection sensor 16 to the CPU 10. Based on this detection signal, the CPU 10 recognizes that the rear end portion of the additional recording paper has passed the installation position of the paper detection sensor 16, and after that recognition, the rear end portion of the additional recording paper becomes the printing surface sensor 15. When it is recognized that a preset time necessary for passing the print medium has passed, a control signal for causing the printing surface sensor 15 to finish reading the printing surface of the additional recording sheet is sent from the CPU 10 to the printing surface sensor 15. Sent. When the printing surface sensor 15 receives this control signal, the printing surface sensor 15 stops reading the printing surface of the additional recording paper. Then, the image data of the printing surface of the additional recording sheet transmitted from the printing surface sensor 15 to the CPU 10 is temporarily stored in the storage unit 14 by the CPU 10. At this time, the additional recording paper is stopped in a state in which the leading end portion is in contact with the registration roller 137.

  Subsequently, in step S7-2, the CPU 10 reads the image data of the printing surface of the additional recording paper from the storage unit 14 and records the identification information (that is, the identification mark of the destination data) in which the destination information and the registration number of the document data are recorded. 41) and whether or not an identification mark (that is, the rear identification mark 42) in which the rear information and the registration number of the document data are recorded is determined to be included in the image data. It is determined whether or not the front identification mark 41 and the rear identification mark 42 are included.

  The CPU 10 has an identification mark (i.e., a front identification mark 41) in which the registration information and the registration number of the document data are recorded, and an identification mark (that is, the rear identification mark 42) in which the registration information and the registration number of the document data are recorded. If it is determined that it is not included in the image data (NO in S7-2), a recording sheet other than the additional recording sheet on which the front identification mark 41 and the rear identification mark 42 are printed is set in the manual feed tray 133. In other words, it is set such that the surface of the additional recording sheet on which the front identification mark 41 and the rear identification mark 42 are printed is on the manual feed tray 133 side. Subsequently, in step S7-3, the discharge direction switching guide 139 is switched in the direction indicated by the solid line in FIG. Then, the additional recording paper is transported toward the first paper discharge roller 138 by the registration roller 137, and the additional recording paper that has passed through the image forming unit 12 is not printed on the additional recording paper by the image forming unit 12. The recording paper is discharged to the face-up tray 141 by the first paper discharge roller 138. At this time, the configuration may be such that the additional recording paper is discharged to the face-down tray 142.

  Subsequently, in step S7-4, under the control of the CPU 10, the operation display unit 11 displays that it is not a recording sheet for performing additional printing (that is, an additional recording sheet).

  In step S7-2, the CPU 10 identifies an identification mark (i.e., the identification mark 41) where the registration information and the registration number of the document data are recorded, and an identification mark (which includes the registration number of the backward information and the document data). That is, if it is determined that the rear identification mark 42) is included in the image data (YES in S7-2), the registration number is extracted by the CPU 10 and temporarily stored in the storage unit 14 in step S7-5. Is done. Then, the CPU 10 once extracts the front information or the rear information recorded in the identification mark read first by the printing surface sensor 15 from the front identification mark 41 and the rear identification mark 42 from the image data. It is stored in the storage unit 14.

  Subsequently, in step S7-6, as shown in FIG. 9, on the image data of the printing surface of the additional recording paper read and generated by the printing surface sensor 15, the CPU 10 sets the origin (X, Y) = The position of the corner 44a closest to the origin (0, 0) of the identification mark 44 read first by the printing surface sensor 15 among the front identification mark 41 and the rear identification mark 42 with respect to (0, 0). After (X3, Y3) is acquired, the position (X3, Y3) is temporarily stored in the storage unit 14 as the actual position (X3, Y3) of the identification mark 44 read first by the printing surface sensor 15. . The actual position of the identification mark 44 is the actual position of the identification mark and corresponds to the actual position information of the identification mark.

  Subsequently, in step S <b> 7-7, the CPU 10 transmits the registration number of the document data, the destination information or the rear information, and the actual position of the identification mark 44 to the personal computer 3 through the interface unit 17.

  In step S 7-8, the interface unit 17 receives a recording paper discharge command or print data of character string data added to the document data stored in the registration information storage unit 34. When the discharge command or its print data is input to the CPU 10 (S7-8 YES), in step S7-9, the CPU 10 determines whether the discharge command or the print data is input from the interface unit 17 in step S7-8. Control of discharging processing of additional recording paper or printing processing on additional recording paper is performed as follows. In step S7-8, if no discharge command or print data is input from the interface unit 17 to the CPU 10 (NO in S7-8), the process returns to step S7-8.

  In step S7-8, when the interface unit 17 receives the recording paper discharge command and the discharge command is input from the interface unit 17 to the CPU 10 (YES in S7-8), it is necessary to print on the additional recording paper. Therefore, in step S7-9, the discharge direction switching guide 139 is switched in the direction indicated by the solid line in FIG. Then, the additional recording paper is transported toward the first paper discharge roller 138 by the registration roller 137, and the additional recording paper that has passed through the image forming unit 12 is not printed on the additional recording paper by the image forming unit 12. The recording paper is discharged to the face-up tray 141 by the first paper discharge roller 138. Under the control of the CPU 10, the operation display unit 11 displays that it is not necessary to print on the recording paper (that is, the additional recording paper). At this time, the configuration may be such that the additional recording paper is discharged to the face-down tray 142.

In step S7-8, when the interface unit 17 receives the print data and the print data is input to the CPU 10 from the interface unit 17 (S7-8 YES), the CPU 10 prints the print data in step S7-9. The bitmap image data is generated so that the image of the character string data is printed at the position based on the print position information of the character string data or the corrected print position information. Then, the CPU 10 sends the generated image data in the bitmap format to the image forming unit 12. Similarly to the above, the image forming unit 12 performs additional printing on the additional recording paper based on the image data, and the printed additional recording paper is discharged to the face-down tray 142. Then, as shown in FIG. 10, on the printed additional recording paper discharged to the face-down tray 142, the character string data image 45 is additionally printed in the entry field 43a of the entry table 43 without misalignment. ing.

  Next, the operation of the personal computer 3 when printing the character string data on the additional recording paper in the image forming system 1 of the present embodiment will be described. In the personal computer 3 of the present embodiment, the interface unit 35 in step S8-1, the registration number of the document data transmitted from the image forming apparatus 2 in the above-described step S7-7, the destination information or the rear information, and the identification mark 44. , The registration number of the document data received from the interface unit 35, the destination information or the backward information, and the actual position of the identification mark 44 are sent to the CPU 30.

  Subsequently, in step S8-2, the CPU 30 searches whether or not the same registration number as the received registration number is stored in the registration information storage unit 34. When the CPU 30 determines that the same registration number as the received registration number is not stored in the registration information storage unit 34 (NO in S8-2), the document data corresponding to the received registration number is stored in the registration information storage unit 34. Will not be remembered. Subsequently, in step S <b> 8-3, the CPU 30 transmits a recording sheet discharge command for discharging the additional recording sheet without causing the image forming apparatus 2 to print, to the image forming apparatus 2 via the interface unit 35. The

  In step S8-2, if the CPU 30 determines that the same registration number as the received registration number is stored in the registration information storage unit 34 (YES in S8-2), it corresponds to the received registration number. The document data is stored in the registration information storage unit 34. Further, in step S8-4, the CPU 30 searches whether the unprinted information of the document data is stored in the registration information storage unit 34 in association with the document data corresponding to the received registration number. If the CPU 30 determines that the unprinted information of the document data is not stored in the registration information storage unit 34 in association with the document data corresponding to the received registration number (NO in S8-4), step In step S <b> 8-3, the CPU 30 transmits a recording sheet discharge command for discharging the additional recording sheet without causing the image forming apparatus 2 to print, to the image forming apparatus 2 via the interface unit 35.

  If the CPU 30 determines in step S8-4 that the unprinted information of the document data is stored in the registration information storage unit 34 in association with the document data corresponding to the received registration number ( In step S8-5, the CPU 30 determines which of the front information and the rear information is received. If the CPU 30 determines that the destination information is received (YES in S8-5), the additional recording sheet is conveyed from the destination identification mark 41 side in the image forming apparatus 2. Subsequently, in step S8-6, the CPU 30 compares the actual position of the identification mark 44 with the destination mark position stored in the registration information storage unit 34 in association with the document data corresponding to the received registration number. .

  If the CPU 30 determines that the actual position of the identification mark 44 is equal to the previous mark position (YES in S8-6), in step S7-1, the positional deviation of the conveyance of the additional recording paper in the image forming apparatus 2 is performed. In step S8-7, the CPU 30 stores the document data corresponding to the received registration number, and the unprinted information associated with the document data and the character string data corresponding to the unprinted information. The print position information is read from the registration information storage unit 34. Then, the CPU 30 extracts character string data corresponding to the unprinted information from the document data corresponding to the received registration number and the unprinted information associated with the document data. Then, the CPU 30 generates print data of character string data from the character string data corresponding to unprinted information and the print position information in the document data. The print data is obtained by converting character string data, print position information of the character string data, a print command, and the like into page description language data such as postscript data. Then, the print data of the generated character string data is transmitted to the image forming apparatus 2 via the interface unit 35 by the CPU 30.

  Subsequently, in step S8-8, the CPU 30 changes the unprinted information of the document data corresponding to the received registration number to the printed information and stores it in the registration information storage unit 34. That is, the character string data corresponding to the unprinted information in the received document data of the registration number is changed to printed.

  In step S8-6, if the CPU 30 does not equal the actual position of the identification mark 44 and the previous mark position (NO in S8-6), the image forming apparatus 2 carries the additional recording paper in step S7-1. In step S8-9, the CPU 30 causes the CPU 30 to identify the previous mark position (X1, Y1) and the actual position (X3, Y3) of the identification mark 44 from the previous mark position (X1, Y1). The positional deviation correction data for correcting the positional deviation of the 44 actual positions (X3, Y3) is generated. That is, the misregistration correction data is for correcting a misregistration of printing due to a misregistration of conveyance of the additional recording paper.

  Subsequently, in step S8-10, the CPU 30 obtains the document data corresponding to the received registration number and the print position information of unprinted information associated with the document data and character string data corresponding to the unprinted information. The information is read from the registration information storage unit 34. Then, the print position information of the character string data corrected based on the positional deviation correction data is generated by the CPU 30.

  Then, from the print position information of the character string data corrected by the CPU 30 based on the positional deviation correction data and the character string data corresponding to the unprinted information among the document data corresponding to the received registration number, The corrected print data of the character string data in which the print position information of the character string data corresponding to the print information is corrected is generated. The print data is obtained by converting character string data, corrected printing position information of the character string data, a print command, and the like into page description language data such as postscript data.

  Subsequently, in step S8-11, the corrected print data of the character string data in which the print position information of the character string data corresponding to the unprinted information of the document data is corrected is image-formed by the CPU 30 via the interface unit 35. Sent to device 2.

  Subsequently, in step S8-12, unprinted information of the document data corresponding to the received registration number is changed to printed information and stored in the registered information storage unit 34. That is, the character string data corresponding to the unprinted information in the received document data of the registration number is changed to printed.

  In step S8-5, if the CPU 30 determines that the rear information is received (that is, the destination information is not received) (S8-5 NO), it is added in the image forming apparatus 2. That is, the recording paper is being conveyed from the rear identification mark 42 side, and in step S8-13, the CPU 30 associates the actual position of the identification mark 44 with the document data corresponding to the received registration number. It is compared with the rear mark position stored in the registration information storage unit 34.

  If the CPU 30 determines that the actual position of the identification mark 44 is the same as the rear mark position (YES in S8-13), the image forming apparatus 2 moves the additional recording paper from the rear identification mark 42 side to a positional deviation of the conveyance. It will be transported without. Furthermore, since the reception of the backward information is recognized by the CPU 30 in step S8-5, the print position information of the character string data corresponding to the unprinted information of the document data of the registration number received by the CPU 30 in step S8-14. Position correction data for generating a rotation of 180 degrees is generated. In other words, the position correction data is for correcting a positional deviation of printing accompanying the conveyance of the additional recording paper from the rear identification mark 42 side in the image forming apparatus 2.

  Subsequently, in step S8-15, the CPU 30 obtains the document data corresponding to the received registration number, and the unprinted information associated with the document data and the print position information of the character string corresponding to the unprinted information. It is read from the registration information storage unit 34. Since the backward information is recognized by the CPU 30, the print position information of the character string corrected based on the position correction data is generated, and the character string data corresponding to the unprinted information rotated by 180 degrees Is generated.

  Then, the CPU 30 calculates the character string corresponding to the unprinted information from the print position information of the character string data corrected based on the position correction data and the character string corresponding to the unprinted information rotated 180 degrees. The corrected print data of the character string data whose print position information is corrected is generated. The print data is obtained by converting character string data, corrected printing position information of the character string data, a print command, and the like into page description language data such as postscript data.

  Subsequently, in step S8-16, the corrected print data of the character string data is transmitted to the image forming apparatus 2 through the interface unit 35 by the CPU 30.

  Subsequently, in step S8-17, the unprinted information of the document data corresponding to the received registration number is changed to the printed information and stored in the registration information storage unit 34. That is, the character string data corresponding to the unprinted information in the received document data of the registration number is changed to printed.

  If the CPU 30 determines in step S8-13 that the actual position of the identification mark 44 is not equal to the rear mark position (NO in step S8-13), the additional recording paper is moved rearward in the image forming apparatus 2. It is conveyed from the identification mark 42 side in a state where there is a displacement of the conveyance. Further, since the reception of the rear information is recognized by the CPU 30 in step S8-5, the CPU 30 determines from the rear mark position (X2, Y2) and the actual position (X3, Y3) of the identification mark 44 in step S8-18. The positional deviation correction data for correcting the positional deviation of the actual position (X3, Y3) of the identification mark 44 with respect to the rear mark position (X2, Y2) is generated. Furthermore, the CPU 30 generates position correction data for rotating the print position information of the character string data corresponding to the unprinted information of the received document data of the registration number by 180 degrees.

  Subsequently, in step S8-19, the CPU 30 obtains the document data corresponding to the received registration number, and the unprinted information associated with the document data and the print position information of the character string corresponding to the unprinted information. It is read from the registration information storage unit 34. Since the backward information is recognized by the CPU 30, the positional deviation correction data and the print position information of the character string data corrected based on the position correction data are generated, and the unprinted information rotated by 180 degrees Character string data corresponding to is generated.

  Then, from the misalignment correction data and the print position information of the character string data corrected based on the position correction data by the CPU 30 and the character string data corresponding to the unprinted information rotated by 180 degrees, unprinted information is obtained. The corrected print data of the character string data in which the print position information of the character string data corresponding to is corrected is generated. The print data is obtained by converting character string data, corrected printing position information of the character string data, a print command, and the like into page description language data such as postscript data.

  Subsequently, in step S8-20, the corrected print data of the character string data is transmitted to the image forming apparatus 2 through the interface unit 35 by the CPU 30.

  Subsequently, in step S8-21, unprinted information of the document data corresponding to the received registration number is changed to printed information and stored in the registered information storage unit 34. That is, the character string data corresponding to the unprinted information in the received document data of the registration number is changed to printed.

  As described above, in the image forming processing system 1 according to the present embodiment, the recording paper on which the front identification mark 41 and the rear identification mark 42 are printed is in a state in which the conveyance position is shifted from the front identification mark 41 side. In the case of being transported with the character string data, the character string data has been corrected based on the positional deviation between the actual position of the leading identification mark and the leading mark position, and the print position information of the character string data has been corrected according to the positional deviation of the transport. Since the print data is generated, the character string data image can be accurately printed at the position on the recording paper that should be printed. In this case, the same effect can be obtained even when one identification mark is printed on the recording paper.

  Further, in the case of the image forming processing system 1 of the present embodiment, the recording paper on which the front identification mark 41 and the rear identification mark 42 are printed is conveyed from the rear identification mark 42 side with no conveyance positional deviation. 2, the backward information recorded in the backward identification mark 42 is recognized by the CPU 30, so that the print position information of the character string data and the corrected print data of the character string data obtained by rotating the character string data by 180 degrees are generated. Therefore, it is possible to accurately print an image of character string data at a position on the recording paper that should be printed.

  In the image forming processing system 1 of the present embodiment, the recording paper on which the front identification mark 41 and the rear identification mark 42 are printed is transported from the rear identification mark 42 side with a transport misalignment. , The CPU 30 recognizes the backward information recorded in the backward identification mark 42 and acquires the positional deviation between the actual position of the backward identification mark and the forward mark position, thereby obtaining the print position information of the character string data. The character string data is rotated 180 degrees, and the corrected print data of the character string data in which the print position information of the character string data is corrected corresponding to the positional deviation of the transport is generated. An image of character string data can be accurately printed at a position on the power recording paper.

  In the image forming processing system 1 of the present embodiment, the registration information storage unit 34 is mounted on the personal computer 3, but the present invention is not limited to this, and the registration information storage unit is included in the image forming apparatus 2. 34, and the CPU 10 of the image forming apparatus 2 may perform the same control as the CPU 30 of the personal computer 3 described above. This makes it possible to obtain the same effect as described above.
