  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic front view showing the configuration of an MFP (Multi-Function Peripheral) as an image forming apparatus according to the first embodiment of the present invention, and FIG. 2 is a block diagram showing the configuration of the MFP shown in FIG. is there.

  The MFP 100 includes a CPU 101, a memory 102, a hard disk 103, an operation panel unit 104, an ADF (Auto Document Feeder) 105, an image reading unit 106, a paper feeding unit 107, an image forming unit 108, a folding unit 109, a paper discharge unit 110, and a communication. An interface 111 is included, and these are connected to each other via a bus 112 for exchanging signals.

  The CPU 101 performs control of each part and various arithmetic processes according to a program. The memory 102 includes a ROM that stores various programs and various data in advance, and a RAM that temporarily stores programs and data as a work area. The hard disk 103 stores various programs including an operating system and various data.

  The operation panel unit 104 includes a touch panel, a numeric keypad, a start button, a stop button, and the like, and is used for displaying various information and inputting various instructions.

  The ADF 105 conveys one or more set originals one by one to a predetermined reading position of the image reading unit 106, and sequentially discharges the originals after image reading.

  The image reading unit 106 irradiates the original set at a predetermined reading position or the original conveyed to the predetermined reading position by the ADF 105 with a light source such as a fluorescent lamp, and photoelectrically converts the reflected light with a light receiving element such as a CCD. Then, image data is generated from the electrical signal.

  The paper feeding units 107a to 107c store paper as a recording material used for printing. The paper feeding unit 107 (generic name for 107a to 107c) sends out the stored paper to the image forming unit 108 one by one.

  The image forming unit 108 prints various data on a sheet using a known image forming process such as an electrophotographic process including charging, exposure, development, transfer, and fixing processes.

  The folding unit 109 performs folding processing on the printed paper conveyed from the image forming unit 108. For folding, it is folded in two at the center of the paper, is often used to put in a sealed letter, is folded in three at two places, 1/3 and 2/3 from the edge of the paper, and the paper is folded into a Z shape and conveyed Z-folding that finishes to approximately half the length along the direction is included.

  The paper discharge unit 110 discharges the printed paper conveyed from the image forming unit 108 or the folding unit 109. In the paper discharge unit 110, the finishing process may be performed on the paper. Examples of the finishing process include a stapling process for stapling a bundle of sheets, a punching process for forming a filing hole at the end of the sheet, and a trimmer process for cutting the end of the sheet.

  The communication interface 111 is an interface for communicating with an external device, a network interface according to standards such as Ethernet (registered trademark), token ring, and FDDI, a serial interface such as USB and IEEE1394, a parallel interface such as SCSI and IEEE1284, and BLUETOOTH. (Registered trademark), IEEE802.11, HomeRF, IrDA and other wireless communication interfaces, a telephone line interface for connecting to a telephone line, and the like can be used.

  Note that the MFP 100 may include components other than the above-described components, or may not include some of the above-described components.

  Next, the operation of MFP 100 in the present embodiment will be described.

  3 to 5 are flowcharts showing a processing procedure in the MFP 100 according to the first embodiment. 3 to 5 is stored as a program in the hard disk 103 of the MFP 100 and executed by the CPU 101.

  In the present embodiment, a case will be described in which MFP 100 executes printing by pasting an object image included in a received print job onto form data stored in MFP 100 in advance.

  First, the MFP 100 receives a print job from another device such as a PC (personal computer) on the network via the communication interface 111 (S101). Note that the print job may be a print job related to copying of a document instructed through the operation panel unit 104.

  Subsequently, the lower limit value X of the image reduction rate input in advance by the user and stored in the hard disk 103, for example, is read into the memory 102 (S102). However, the lower limit value X of the image reduction rate may be included in the print job. In this case, the lower limit value X of the image reduction rate is acquired from the received print job. Note that the lower limit value X of the image reduction rate is represented by a real number smaller than 1.

  Subsequently, the folding number N and folding position information are read into the memory 102 (S103). Here, the value of the folding number N is included in the print job and is represented by an integer. The folding position information is stored in advance in the hard disk 103, for example. The folding position information is represented by a distance (mm) from the edge of the paper to the folding position, for example.

  Subsequently, for example, form data stored in the hard disk 103 is read into the memory 102 (S104). Form data is fixed data to which an object image included in a print job is to be pasted.

  Subsequently, an object image is read into the memory 102 from the received print job (S105).

  Then, the object image is pasted on the form data read in step S104 (S106).

  Subsequently, the folding number counter M is initialized to “0” (S107). The folding number counter M is represented by an integer.

  In step S108, the folding number counter M is incremented by “1”.

  In step S109, it is determined whether or not the folding number counter M is larger than the folding number N.

  When the folding number counter M is larger than the folding number N (S109: YES), it is determined that there is no folding position for which it has not been examined whether the image is applied or not, and the process proceeds to step S110.

  In step S110, printing is executed. That is, the CPU 101 of the MFP 100 instructs the paper feeding unit 107 to feed the paper specified in the received print job, and pastes an object image on the form data to the image forming unit 108. An instruction is given to form an image of the page data created in addition. In addition, the CPU 101 instructs the folding unit 109 to perform the folding process specified in the received print job on the sheet sent from the image forming unit 108 and also instructs the folding unit 109 to perform the folding process. An instruction is given to discharge the sheet sent from 109. If a series of image forming processing and folding processing are performed and the printed matter is discharged, the printing processing ends.

  For example, in the case of a print job in which folding processing is not designated (fold number N = 0), M = 1 and N = 0 in step S109 (step S109: YES), and correction processing for removing the image from the crease (step S109: YES). Printing is executed without performing step S114 described later (S110).

  On the other hand, when the folding number counter M is equal to or smaller than the folding number N (S109: NO), the process proceeds to step S111. For example, in the case of a print job in which folding processing is specified (fold number N ≧ 1), M ≦ N is initially set.

  In step S111, the object image counter R is initialized to “0”. The object image counter R is represented by an integer.

  Subsequently, the position of the object image is recognized (S112). The position of the object image can be recognized by determining at which position on the paper the object image is drawn based on the image density, for example.

  In step S113, it is determined whether or not the number of object images straddling the Mth fold is greater than R. Here, the value of R stores the initial value “0” or the number of object images that are not subjected to correction processing for straddling creases in step S206 described later. In this way, whether or not to execute the correction process by comparing the number of object images determined to straddle the folding position with the number of object images determined not to perform the correction process across the fold line. It is determined whether there is a place that needs to be examined.

  FIG. 6 shows an example of page data including an object image straddling a fold.

The page data 500 includes an object image 501 and an object image 502. Here, the object image 501 is a character image, and the object image 502 is a photographic image or a graphic image. Further, the page data 500, the first fold F ₁ and the second fold F ₂ and is shown in the case of e.g. folding process is folding Z. In FIG. 6, the object image 501 straddles the _first crease F1, and the object image 502 straddles the _second crease F2. Reference numeral “510” in the drawing indicates a printable area on the paper.

  If it is determined in step S113 that the number of object images straddling the Mth fold is greater than R (initial value is “0”) (S113: YES), correction processing is performed on the (R + 1) th object image. (S114).

  On the other hand, if it is determined in step S113 that the number of object images straddling the Mth fold is R or less (the initial value is “0”) (S113: NO), the process returns to step S108, and the process for the next fold is performed. Is called.

  Next, the correction process in step S114 will be described with reference to FIG.

  First, the CPU 101 measures a distance U from the fold line to the upper side of the object image straddling the fold line, and a distance L from the fold line to the bottom side of the object image straddling the fold line (S201). For example, in the example of FIG. 6, U (1) and L (1) are measured for the object image 501, and U (2) and L (2) are measured for the object image 502.

  Subsequently, it is determined whether or not the distance U from the crease to the upper side of the object image straddling the fold is larger than the distance L from the crease to the bottom of the object image straddling the crease (S202).

When L <U (S202: YES), the reduction ratio Y is calculated by the equation Y = U / (U + L) (S203). Then, it is determined whether or not the calculated reduction rate Y is equal to or greater than the lower limit value X of the image reduction rate as a preset threshold (S204). When the calculated reduction ratio Y is equal to or greater than the lower limit value X (S204: YES), the CPU 101 reduces the object image while fixing the upper side position of the object image. Thus, for example, as shown in FIG. 7, in the page data 600 after the reduction treatment, the object image 601 is reduced will be located above the fold F _1. As an example of the object image reduction method, for example, when U (1) = 1 and L (1) = 9, there is a method of thinning out at a rate of 1 out of 10 points constituting the object image. . On the other hand, when the calculated reduction ratio Y is smaller than the lower limit value X (S204: NO), the CPU 101 increments the object image counter R by “1” without performing the reduction process, and ends the correction process. . As a result, it is possible to prevent a situation in which the object image becomes too small and difficult to see.

When L ≧ U (S202: NO), the reduction ratio Y is calculated by the equation Y = L / (U + L) (S207). Then, it is determined whether or not the calculated reduction ratio Y is equal to or greater than the lower limit value X of the image reduction ratio as a preset threshold value (S208). When the calculated reduction ratio Y is equal to or higher than the lower limit value X (S208: YES), the CPU 101 reduces the object image while fixing the base position of the object image. Thus, for example, as shown in FIG. 7, in the page data 600 after the reduction treatment, the object image 602 is reduced will be positioned below the fold F _2. On the other hand, when the calculated reduction ratio Y is smaller than the lower limit value X (S208: NO), the CPU 101 increments the object image counter R by “1” without performing the reduction process, and ends the correction process. .

  When the correction process in step S114 is completed, the process returns to step S113, where it is confirmed whether there are other object images that straddle the Mth fold, and until it is determined that the number of object images that straddle the Mth fold is R or less. The correction process (S114) regarding the Mth fold is repeated.

  As described above, when the MFP 100 according to the first embodiment accepts a print job, the MFP 100 recognizes the position of the crease formed by the folding process performed on the paper, and arranges the fold at the recognized position and the page included in the print job. It is determined whether or not the image to be matched is at least partially, and when the fold and the image match at least partially, correction processing for removing the image from the fold is executed.

  Therefore, when the paper after image printing is folded, it is possible to prevent the image printed on the paper from becoming difficult to see due to the crease. This makes it easier for the user to grasp the content printed on the paper.

  Next, a second embodiment of the present invention will be described. The correction process in the first embodiment is a process for reducing the size of the image, whereas the correction process in the second embodiment is a process for moving the position of the image. Yes. Hereinafter, the second embodiment will be described focusing on differences from the first embodiment.

  8 to 10 are flowcharts showing a processing procedure in the MFP 100 according to the second embodiment. 8 to 10 is stored as a program in the hard disk 103 of the MFP 100 and is executed by the CPU 101.

  The processes in steps S301 to S305 shown in FIG. 8 are the same as the processes in steps S101 and S103 to S106 shown in FIG.

  In step S306, the CPU 101 measures how much margin distance A is present in the page data created by pasting the object image on the form data on the sheet designated in the received print job. To do. The unit of the margin distance A is, for example, mm.

  FIG. 11 shows an example of page data including an object image straddling a fold.

In the page data 500a, the object image 501a straddles the _first fold F1, and the object image 502a straddles the _second fold F2. In FIG. 11, the margin distance A is given by the distance between the bottom of the object image 502a and the bottom of the printable area 510a on the paper.

  In the second embodiment, correction processing related to an object image 502a that is a photographic image or a graphic image will be described. Correction processing related to the object image 501a that is a character image will be described in a third embodiment to be described later. However, the correction process related to the object image 501a can be performed in the same manner as the correction process related to the object image 502a.

  In this embodiment, the downward margin distance A is measured on the assumption that object images are arranged vertically on a page, but the present invention is not limited to this. In the present invention, for example, the margin distance in the upward direction may be measured, and further, the margin distance in the right direction or the left direction may be measured on the assumption that the object images are arranged side by side on the page.

  Since the processes in steps S307 to S314 shown in FIG. 8 are the same as the processes in steps S107 to S114 shown in FIG.

  However, in step S308, the folding number counter M is incremented by “1” and the margin register I is initialized to “0”. The unit of the margin register I is the same as the unit (mm) of the margin distance A.

  Next, the correction process in step S314 will be described with reference to FIG.

  First, the CPU 101 measures the distance U from the crease to the upper side of the object image across the crease (S401). For example, in the example of FIG. 11, U (2) is measured for the object image 502a.

  Subsequently, it is determined whether or not the distance U from the crease to the upper side of the object image across the crease is equal to or less than the margin distance A measured in step S306 (S402).

  When the distance U is less than or equal to the margin distance A (S402: YES), the value of the moving distance C is set to the distance U (S403). The unit of the movement distance C is the same as the unit (mm) of the margin distance A.

Subsequently, the CPU 101 moves the object image straddling the Mth fold line and the object image arranged below the object image by the movement distance C (S404). Thus, for example, as shown in FIG. 12, the page data 600a after the moving process, the object image 602a that is moved will be positioned below the fold F _2.

  Subsequently, it is determined whether or not the moving distance C is larger than the margin register I (S405). Here, it is determined whether or not the margin distance A needs to be corrected by moving the object image. If the moving distance C is less than or equal to the margin register I (S405: NO), the correction process is terminated and the process returns to the flowchart of FIG.

  When the moving distance C is larger than the margin register I (S405: YES), the values of the moving distance C and the margin register I are subtracted from the value of the margin distance A (S406). Subsequently, the CPU 101 sets the value of the margin register I to the value of the movement distance C, ends the correction process, and returns to the flowchart of FIG. Here, when there are a plurality of object images straddling the same M-th fold, the margin register I indicates the movement distance of the object image processed immediately before.

  On the other hand, when it is determined in step S402 that the distance U is larger than the margin distance A (S402: NO), the CPU 101 increments the object image counter R by “1” without performing the movement process, and performs the correction process. Exit. As a result, it is possible to prevent the object image from being divided halfway or being printed on the next page.

  As described above, according to the second embodiment as well, when the paper after image printing is folded, it is possible to prevent the image printed on the paper from becoming difficult to see due to the crease.

  Next, a third embodiment of the present invention will be described. The correction process in the third embodiment is the same as the correction process in the second embodiment in that it is a process of moving the position of the image. However, the correction processing in the third embodiment is applied when the image is a character image, and the position of the image is set so that the crease is positioned in the space between adjacent character strings in the character image. It is different from the correction process in the second embodiment in that it is a process to be moved. Here, the character string means a character string arranged on one straight line, and corresponds to, for example, one line. Hereinafter, the third embodiment will be described focusing on differences from the second embodiment.

  FIG. 13 to FIG. 15 are flowcharts showing processing procedures in the MFP 100 according to the third embodiment. Note that the algorithm shown in the flowcharts of FIGS. 13 to 15 is stored as a program in the hard disk 103 of the MFP 100 and is executed by the CPU 101.

  The processes in steps S501 to S507 shown in FIG. 13 are the same as the processes in steps S301 to S307 shown in FIG.

  In step S508, the CPU 101 initializes the object image list. The object image list is a list of all object images (character images) included in the print job, and includes information on whether correction processing has already been performed on each object image. The object image list is recorded in the memory 102. In the initial state, all object images in the object image list are uncorrected.

  The processes in steps S509 to S515 shown in FIGS. 13 and 14 are also the same as the processes in steps S308 to S314 shown in FIG.

  However, in step S513, the position of the object image can be recognized by determining at which position on the paper the character image is drawn based on, for example, the image density or tag bit information.

  Next, the correction process in step S515 will be described with reference to FIG.

  First, the CPU 101 determines whether or not the object image to be processed has already been corrected by referring to the object image list (S601).

  When the object image to be processed has already been corrected (S601: YES), the CPU 101 increments the object image counter R by “1” and ends the correction process. That is, when one object image straddles a plurality of folds, the object image moving process is performed only once and not performed a plurality of times. In general, this is because the first movement process can often cope with the situation, and conversely, the character string deviated from the crease in the first movement process is prevented from entering the crease again.

  Subsequently, the CPU 101 measures the distance U from the crease to the upper side of the character string across the crease (S602). For example, in the example of FIG. 11, U (3) is measured for the object image 501a.

  The processes in steps S603 to S608 shown in FIG. 15 are the same as the processes in steps S402 to S407 shown in FIG.

Incidentally, the movement of the image in step S605, for example, as shown in FIG. 12, the page data 600a after the moving process, the space between the strings adjacent in the object image 601a, that fold F ₁ is located Become.

  In step S609, the object image to be processed in the object image list is corrected.

  As described above, according to the third embodiment, it is possible to prevent the character string of the character image printed on the paper from becoming difficult to see due to the crease when the paper after the character image is printed is folded. it can. Since the correction process of the third embodiment can be applied only to a character image, when executing a print job including a photographic image or a graphic image, the correction process of the first or second embodiment is the same as that of the first or second embodiment. It is desirable to implement in combination.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims.
