The control unit is previously conveyed by the conveying unitru shi t and subsequent no shi When the processing position in the width direction by the processing member differs from that of the workpiece, The preceding transport Using the processing member that minimizes the distance the sheet moves from the processing position, The subsequent Processing the sheet The control unit then performs standby control to process the subsequent sheet while keeping the processing member, whose processing position in the width direction of the sheet being transported further behind the subsequent sheet is within a predetermined range from the processing position of the preceding sheet, waiting within a predetermined range from the position where the preceding sheet was processed. do. 【0007】 Furthermore, in the above configuration, the control unit is If the processing position of the sheet being transported first is within a predetermined value from the position of the side edge of the subsequent sheet in the transport path, avoidance control is performed to move the processing member located within a predetermined value from the side edge of the subsequent sheet to an avoidance position, which is moved by a predetermined amount in the direction away from the subsequent sheet from a waiting position that waits within a predetermined range from the processing position of the sheet being transported first, and to process the subsequent sheet. 【0008】 Furthermore, the processing apparatus of the present invention comprises a conveying unit for conveying a sheet, a processing unit provided with a plurality of processing members for processing the sheet along the conveying direction of the conveying unit, and a moving unit for moving the processing members in a width direction intersecting the conveying direction, and a control unit for controlling the operation of the moving unit, wherein when the processing positions in the width direction by the processing members on a sheet conveyed first by the conveying unit and a subsequent sheet are different, the control unit processes the subsequent sheet using the processing member that minimizes the distance moved from the processing position of the first sheet conveyed first, and when the processing position of the first sheet conveyed first is within a predetermined value from the position of the side edge in the conveying path of the subsequent sheet, the processing member located within a predetermined value from the side edge of the subsequent sheet is moved by a predetermined amount from a waiting position within a predetermined range from the processing position of the first sheet conveyed first to an avoidance position, and the subsequent sheet Execute avoidance control during processing. 【0009】 Furthermore, the processing apparatus of the present invention comprises a conveying unit for conveying a sheet, a processing unit provided with a plurality of processing members for processing the sheet along the conveying direction of the conveying unit, and a moving unit for moving the processing members in a width direction intersecting the conveying direction, and a control unit for controlling the operation of the moving unit, The control unit, When the processing positions in the width direction by the processing member on a sheet being transported first by the transport unit and a subsequent sheet are different, the subsequent sheet is processed using the processing member that minimizes the distance traveled from the processing position of the first sheet being transported. When the processing positions on the first sheet being transported first and the subsequent sheet are different, and the processing position on a sheet further behind the subsequent sheet is within a predetermined range from the processing position of the first sheet being transported first, the processing member that processed the first sheet is moved to the processing position of the subsequent sheet, and movement control is possible to perform this process. The system determines whether to perform the standby control or the movement control based on the user's instructions. 【0010】 Also, In the above configuration, The processing member is a slitter, the moving part is a slitter moving part, and the processing part is a slitter part. A guide is provided for removing the scraps generated when the sheet is cut by the slitter from the transport path, and a guide moving unit is provided for moving the guide in the width direction. The control unit controls the guide moving unit so that the scraps generated at the side edges of the sheet when the sheet is cut by the slitter are removed from the transport path by the guide. 【0011】 Furthermore, The processing apparatus of the present invention comprises a conveying unit for conveying a sheet, a processing unit provided with a plurality of processing members for processing the sheet along the conveying direction of the conveying unit, and a moving unit for moving the processing members in a width direction intersecting the conveying direction, a control unit for controlling the operation of the moving unit, and a cutting device located upstream of the processing unit, which cuts a sheet conveyed in a first direction along a second direction perpendicular to the first direction to form a plurality of sheets. The conveying unit sequentially conveys the preceding sheet and the subsequent sheet cut by the cutting device in the conveying direction, which is the second direction perpendicular to the first direction. When the processing positions in the width direction by the processing members of the preceding sheet and the subsequent sheet are different, the control unit selects the processing member that minimizes the distance traveled from the processing position of the preceding sheet cut from the same sheet by the cutting device, and processes the subsequent sheet. [Effects of the Invention] 【0012】 According to the present invention, when the processing positions in the width direction of the sheet conveyed in advance by the conveying unit and the subsequent sheet by the processing member are different, the control unit uses the processing member for which the moving distance from the processing position of the sheet conveyed in advance is minimized to process the subsequent sheet. Furthermore, a waiting control is executed to process the subsequent sheet while keeping the processed member, whose processing position in the width direction of the sheet being transported further behind the subsequent sheet is within a predetermined range from the processing position of the preceding sheet, waiting within a predetermined range from the position where the preceding sheet was processed. Therefore, when processing the sheet along the conveying direction, when the processing position of the sheet conveyed in advance and the subsequent sheet are different, the time required for processing the sheet can be shortened. 【0013】 Also, the control unit When the processing position of the sheet being transported first is within a predetermined distance from the side edge of the subsequent sheet in the transport path, avoidance control is performed to move the processing member located within a predetermined distance from the side edge of the subsequent sheet from a waiting position within a predetermined range from the processing position of the sheet being transported first to an avoidance position, which is moved by a predetermined amount in the direction away from the subsequent sheet, and then process the subsequent sheet. When executing This prevents narrow scraps from getting stuck in the transport path and causing paper jams. 【0014】 Also, the control unit When the processing positions in the width direction by the processing member differ between a sheet being transported first by the transport unit and a subsequent sheet, the subsequent sheet is processed using the processing member that minimizes the distance traveled from the processing position of the first sheet being transported. When the processing position of the first sheet being transported is within a predetermined value from the position of the side edge of the subsequent sheet in the transport path, the processing member located within a predetermined value from the side edge of the subsequent sheet is moved by a predetermined amount from a waiting position within a predetermined range from the processing position of the first sheet to an avoidance position, and the subsequent sheet is processed using avoidance control. This shortens the time required for sheet processing while preventing narrow scraps from remaining in the transport path and causing paper jams. 【0015】 Also, The control unit When the processing positions in the width direction by the processing member on a sheet that is conveyed first by the conveying unit and a subsequent sheet are different, the subsequent sheet is processed using the processing member that minimizes the distance traveled by the first sheet from its processing position. When the processing positions of the sheet conveyed in advance and the subsequent sheet are different, and the processing position of the sheet further behind the subsequent sheet is within a predetermined range from the processing position of the sheet conveyed in advance, the control unit can execute movement control to move the processing member that has processed the sheet conveyed in advance to the processing position of the subsequent sheet and process the subsequent sheet, and determine whether to execute either the standby control or the movement control based on the instruction of the user. Therefore, The time required for processing the sheet can be further shortened. 【0016】 Furthermore, The processing member is a slitter, the moving part is a slitter moving part, and the processing part is a slitter part.A guide is provided for removing scraps generated when the sheet is cut by the slitter from the transport path, and a guide movement unit is provided for moving the guide in the width direction. When the control unit controls the guide movement unit to remove scraps generated at the side edges of the sheet when the sheet is cut by the slitter from the transport path, the scraps generated using the slitter and guide can be appropriately removed from the transport path. 【0017】 Furthermore, on the upstream side of the processing section, The system includes a cutting device that cuts a sheet being transported in a first direction along a second direction perpendicular to the first direction to form multiple sheets, the transport unit sequentially transports the preceding sheet and the succeeding sheet cut by the cutting device in the transport direction which is the second direction perpendicular to the first direction, and the control unit, when the processing positions in the width direction by the processing member on the preceding sheet and the succeeding sheet are different, selects the processing member that minimizes the distance traveled from the processing position of the preceding sheet cut from the same sheet by the cutting device, and processes the succeeding sheet. The time required for sheet processing can be further reduced.

[Modes for carrying out the invention] 【0019】 (First embodiment) The processing apparatus according to the present invention will be described with reference to the drawings. Figure 1 is a plan view showing the overall configuration of a processing apparatus 100 according to a first embodiment of the present invention. The processing apparatus 100 includes a supply device 2, a cutting device 3, a cross conveyor device 4, a processing device 7, and a stacker device 8 as its main processing mechanisms. The processing apparatus 100 also includes a transport unit 18 for transporting sheets S and a control unit 45 for controlling the operation of the entire processing apparatus 100. The transport direction E by the transport unit 18 of the cutting device 3 and the transport direction F by the transport unit 18 of the processing device 7 are orthogonal. The cutting device 3 transports the sheets S along a first direction A, from right to left in Figure 1. The processing device 7 transports the cut sheets S along a second direction B, from top to bottom in Figure 1. 【0020】 In recent years, the maximum printable sheet size (S) on general-purpose printers has tended to increase, and it is becoming increasingly possible to print on sizes larger than B3. This processing apparatus 100 cuts a printed sheet S larger than a certain size to a predetermined size using an upstream cutting device 3, and then processes the sheet S further in a downstream processing device 7 to remove the excess material and leave only the printed portion. 【0021】 The cutting device 3 can cut even larger sizes than B2, for example. On the other hand, the processing device 7 can process sheets S up to a maximum size of B3. The cutting device 3 cuts the sheet S to a size smaller than the B3 size that the processing device 7 can accept, and then hands the sheet S over to the processing device 7. 【0022】 [Feeding device 2] The supply device 2 includes an air suction belt type air paper feeding unit (not shown), an elevator type paper feeding tray 21 that rises and falls according to the amount of sheets S loaded, and a pair of transport rollers (not shown) that further transport the sheets S fed by the air paper feeding unit downstream in the first direction A. In this embodiment, the device is configured to be able to feed sheets S larger than B2 size. The sheet S is transported by the aforementioned transport roller pair, and when the leading edge of the sheet S reaches the leading edge sensor 31 of the cutting device 3, the pressure between the transport roller pair in the supply device 2 is released, and the sheet S is transported solely by the transport roller 36 in the cutting device 3. 【0023】 [Cutting device 3] The cutting device 3 includes a tip sensor 31 that detects when the leading edge of the sheet S conveyed from the supply device 2 has reached a certain point, a laser sensor 32 that detects the position of the leading edge of the sheet S and a registration mark previously applied to the sheet S, and detects the inclination angle of the printing with respect to the conveying direction of the sheet S, a plurality of conveying rollers 36, and a motor (not shown) that drives the plurality of conveying rollers 36. The tip sensor 31 and the laser sensor 32 are each positioned at two locations in the second direction B, which is perpendicular to the first direction A. 【0024】 The tip sensor 31 has a first sensor 311 and a second sensor 312. The first sensor 311 and the second sensor 312 are located at the same position in the first direction A of the cutting device 3. The first sensor 311 and the second sensor 312 are located at a predetermined distance X apart in the second direction B. 【0025】 The tip sensor 31 detects that the sheet S is tilting during transport when there is a difference of more than a predetermined amount in the timing of detecting the tip of the sheet S by the first sensor 311 and the second sensor 312, respectively. 【0026】 Furthermore, the cutting device 3 has an angle adjustment means 35 that can adjust the angle of the movable blade unit 34 so that it is perpendicular to the printed image, based on the tilt angle of the printed image detected by the laser sensor 32. The angle adjustment means 35 can adjust the angle of the movable blade unit 34 while the sheet S is being transported. The movable blade unit 34 cuts the sheet S by moving the cutting blades (a pair of upper and lower rotating blades) in a direction perpendicular to the direction in which the sheet S is being transported, after stopping the sheet S at a pre-set cutting position. The cut sheet S is then discharged to the cross conveyor device 4 by the transport roller pair 39. 【0027】 Furthermore, if the unwanted scraps J that have been cut by the moving blade unit 34 and have passed the cutting position of the sheet S are longer than a predetermined length, the system is equipped with a rotating guide 37 that can retract the transport guide on the transport path 5 to the reject position and reject the sheet pieces. 【0028】 [Cross conveyor device 4] The cross conveyor device 4 receives the sheets S that have been cut by the cutting device 3 and transported in the first direction A, and transports the sheets S in the second direction B, which is perpendicular to the first direction A, to the processing device 7. Furthermore, the cross conveyor device 4 is positioned downstream of the cutting device 3 and includes an oblique conveying means 404 that receives the sheet S discharged from the cutting device 3 onto an endless belt 401 having a predetermined width, and conveys the sheet S in the second direction B while conveying it diagonally toward the guide wall 402 so that the edge of the received sheet S follows the guide wall 402. 【0029】 [Processing device 7] Figure 2 is a schematic longitudinal cross-sectional view of the processing apparatus 7 and the stacker apparatus 8. In Figure 1, the processing apparatus 7 is equipped with an insertion unit 6 at the upstream end of the apparatus body 101 in the conveying direction F of the sheet S. 【0030】 The insertion unit 6 comprises a supply table 61, a guide plate 68, a supply roller 66, a suction conveying unit 62, and a separation blowing unit 63. The supply table 61 is provided for loading sheets S and supplying the sheets S to the conveying path 5. The supply table 61 is movable up and down by a lifting mechanism (not shown). When supplying sheets S, the lifting mechanism raises the supply table 61 from the standby position to a predetermined supply position where the top sheet S can be suction conveyed by the suction conveying unit 62 and supplied to the conveying path 5. Thus, the supply table 61 is movable between the standby position and the supply position. 【0031】 The guide board 68 contacts the side edge SL of the sheet S, guiding it so that the sheet S is transported downstream without slanting. A pair of supply rollers 66 are installed, one above the other. The suction transport unit 62 includes a suction fan 67, a transport belt 64, and a belt roller 65. The insertion unit 6 supplies a predetermined number of sheets S stacked on the supply table 61 to the transport path 5 one by one from the top using the suction transport unit 62 and the pair of upper and lower supply rollers 66. 【0032】 The separation and blowing unit 63 uses a fan (not shown) to blow air toward the front edge Sf of the sheet S on the supply table 61, separating the top sheet S from the stacked sheets S, which is then sucked onto the suction and conveying unit 62 and conveyed. One of the belt rollers 65 and the lower supply roller 661 of the supply rollers 66 are connected to the paper feeding drive unit 47. The separation and blowing unit 63, the suction fan 67, and the paper feeding drive unit 47 are electrically connected to the control unit 45. 【0033】 A substantially horizontal transport path 5 is configured inside the processing device 7. The transport path 5 is equipped with a transport section 18 on which multiple pairs of upper and lower transport rollers 9 to 17 are installed. The transport rollers 9 to 17 are spaced apart in the transport direction F. Each of the transport rollers 9 to 17 constituting the transport section 18 is connected to a transport drive unit 41 to 44 via a power transmission mechanism (not shown), and each of the transport drive units 41 to 44 is electrically connected to a control unit 45. 【0034】 The transport path 5 is further equipped with multiple light-transmitting detection units 301 to 305 that detect the front edge (downstream edge) Sf or rear edge (upstream edge) Sr of the sheet S or workpiece Q, and each is electrically connected to the interface of the control unit 45. The first detection unit 301, located furthest upstream in the transport direction F of the sheet S, is positioned between the suction transport unit 62 and the supply roller 66 of the insertion unit 6. The second detection unit 302 is positioned near the upstream side of the slitter unit 20. The third detection unit 303 is positioned in the middle of the slitter unit 20. The fourth detection unit 304 is positioned near the upstream side of the crease unit 21. The fifth detection unit 305, located furthest downstream, is positioned near the upstream side of the stacker device 8. 【0035】 The first detection unit 301 detects the front edge Sf of the sheet S before it is gripped by the supply roller 66, or the rear edge Sr of the sheet S that is gripped by the supply roller 66 and being transported, and uses the detected position of the sheet S as a reference to calculate the position of the sheet S that is subsequently being transported on the transport path 5. 【0036】 The second detection unit 302 and the third detection unit 303 detect jams in the sheet S during processing. The fourth detection unit 304 is installed as an auxiliary unit to correct the sheet position information obtained by the first detection unit 301 and make the sheet position information more accurate in case the transport path 5 becomes longer and the positional deviation (transportation error) of the sheet S in the transport direction F on the transport path 5 during processing accumulates. The fifth detection unit 305 detects the discharge of the workpiece Q to the stacker device 8. The fifth detection unit 35 also detects jams, etc., in the workpiece Q in the stacker device 8. 【0037】 A reading unit 26 and a rejection mechanism 25 are provided downstream of the insertion unit 6 as needed. The reading unit 26 reads the image of the position mark printed on the sheet S and detects the reference position for processing in the transport direction F and the width direction W perpendicular to the transport direction F of the processing device 7 for the sheet S. The reading unit 26 also reads the image of the barcode printed at a predetermined position on the sheet S and obtains various processing information to be applied to the sheet S. The reading unit 26 is composed of a CCD sensor or the like. 【0038】 The reject mechanism 25 activates on the sheet S if the position marks or barcodes printed on the sheet S are unclear and therefore cannot be read by the reader unit 26. The reject mechanism 25 drops the unreadable sheet S and collects it in the tray 25a. 【0039】 Furthermore, the transport path 5 is equipped with a processing unit 24 for processing the transported sheet S. The processing unit 24 includes a processing member 29. The processing member 29 processes the sheet S along the transport direction F of the transport unit 18 or along the width direction W intersecting the transport direction. When the processing member 29 processes the sheet S along the transport direction F of the transport unit 18, the processing unit 24 includes a moving unit 51. The moving unit 51 moves the processing member 29 along the width direction W intersecting the transport direction F. 【0040】 In Figure 2, the processing unit 24 is provided with a cutting unit 19 and a creasing unit 21. The cutting unit 19 is composed of three slitter units 20 and a cutter unit 22. The creasing unit 21 forms folds in the sheet S. In the same figure, the slitter unit 20 is shown processing the sheet S along the conveying direction F of the conveying unit 18. The cutter unit 22 and the creasing unit 21 are shown processing the sheet S along the width direction W which intersects the conveying direction F. 【0041】 The slitter section 20, the crease section 21, and the cutter section 22 are each configured as detachable units 20a-20c. Each unit 20a-20c is designed to be detachable from any desired position within the main body 101 of the device using a cassette system. Therefore, depending on the type of processing, the arrangement order of the slitter section 20, the crease section 21, and the cutter section 22 can be changed, or other processing sections 24 such as a mechanism for performing crease processing along the transport direction F instead of the width direction W, a chamfering mechanism, or a perforation forming mechanism can be replaced or added. 【0042】 The slitter section 20 comprises three units, a first unit 20a, a second unit 20b, and a third unit 20c, arranged in order from the upstream side in the conveying direction F. Each unit 20a-20c has two sets of slitters 36, each consisting of upper and lower rotary cutting blades, spaced apart in the width direction W. The slitters 36 are installed by a moving unit 51 so as to be movable in the width direction W, which intersects the conveying direction F of the conveying section 18 of the processing device 7. The slitters 36 constitute a processing member 29 that processes the sheet S along the second direction B, which is the conveying direction F of the conveying section 18 of the processing device 7. The driving force of the rotary drive unit 4l8, which acts as a processing member drive unit that drives the processing member 29, rotates either the upper or lower rotary blade of the conveying path 5, causing the other rotary blade to rotate in a driven motion, thereby cutting along the conveying direction F by the conveying section 18 and forming a cutting line D on the sheet S. 【0043】 In the uppermost first unit 20a, a guide 55 is installed downstream of the slitter 36. The guide 55 removes the scraps J generated when the sheet S is cut by the slitter 36 from the transport path 5. In the uppermost first unit 20a, mainly unnecessary scraps Ja (see Figure 4) from both the left and right edges of the sheet S are cut off. The guide 55 removes the scraps Ja from both the left and right edges cut off by the slitter 36 from the transport path 5, guides them toward the scrap collection section 23, and allows them to fall. 【0044】 Figure 3 is a view of the uppermost unit 20a of the slitter section 20, seen from the downstream side in the conveying direction F. The uppermost unit 20a comprises a frame 37, a slitter 36, a rotary drive unit 48, and a moving unit 51. The frame 37 is composed of a top plate 371, a pair of left and right side plates 372 and 373, and a bottom plate 375. Two handles 375 are attached to the upper surface of the top plate 371. The side plates 372 and 373 are suspended vertically downward from positions near both sides of the top plate 371. 【0045】 The slitter 36 is provided in pairs, one on the left and one on the right, and is movable within the frame 37 in the width direction W by a movable part 51. The slitter 36 consists of a drive blade 58 and a driven blade 59 that are arranged opposite each other vertically. The slitter 36 cuts the sheet S by rubbing the drive blade 58 and the driven blade 59 together. 【0046】 In Figure 2, the rotary drive unit 48 comprises a single drive shaft 460, a power transmission mechanism 393 such as gears and belts, and a rotary drive source such as a motor (not shown). The drive shaft 460 is mounted on the left and right side plates 372 and 373 and is inserted through the rotation centers of both the left and right drive blades 58. The power transmission mechanism 393 is located outside the side plate 372 shown on the right in Figure 2. The rotary drive source is installed on the main body 101 of the device. When the unit 20a is mounted on the main body 101, the driving force of the rotary drive source is transmitted to the power transmission mechanism 393, which rotates the drive shaft 460 and rotates both the left and right drive blades 58 simultaneously. 【0047】 The moving unit 51 moves the slitter 36, which is the workpiece 29, between the workpiece position, the reference position, and a position outside the transport path 5. This moving unit 51 comprises two screw shafts 511, one upper guide shaft 512, one lower guide shaft 513, a pair of left and right gears 514, and two workpiece moving drive units (not shown) which are cutting blade moving drive units (not shown). The four shafts consisting of the screw shafts 511, the upper guide shaft 512, and the lower guide shaft 513 are all mounted between the left and right side plates 372 and 373. The two screw shafts 511 are arranged side by side on the upstream and downstream sides in the transport direction F of the sheet S. 【0048】 The upstream screw shaft 511 has the threaded portion 369 of the left slitter 362 screwed into it in Figure 2. A gear 514 is provided at the end of this upstream screw shaft 511 that protrudes outward from the left plate 373. On the other hand, the downstream screw shaft 511 has the threaded portion 369 of the right slitter 361 screwed into it in Figure 2. A gear 514 is provided at the end of this downstream screw shaft 511 that protrudes outward from the right plate 372. A processing member movement drive unit such as a motor is installed in the main body 101 of the device. When the unit 20 is mounted in the receiving portion 6 of the main body 101, the left and right gears 514 are connected to the two processing member movement drive units of the main body 101, respectively. Then, the drive of each workpiece moving drive unit causes the two screw shafts 511 to rotate independently by a predetermined amount via the gear 514, moving the upper and lower holders 365 and 366 of the slitter 36 to the processing position for processing the sheet S. 【0049】 A waste removal mechanism 27 is located downstream of the slitter section 20. The waste removal mechanism 27 is equipped with a pair of left and right guides 28. Of the first to third units 20a-20c of the slitter section 20, the unit 20b in the center of the conveying direction F and the downstream unit 20c perform cutting of the sheet S along the conveying direction F by the conveying section 18. The waste Jb from the middle of the sheet S that has been cut along the conveying direction F and is no longer needed is removed from the conveying path 5 by the guides 28. 【0050】 Guide 28 is movable in the width direction W by guide movement section 283. Alternatively, instead of guide movement section 283, guide 28 can be configured to move in conjunction with the movement of the slitter 36 of the downstream unit 20c in the width direction W. Guide 28 guides the scraps Jb to the scrap collection section 23 and drops them when the sheet S passes through the scrap removal mechanism 27. 【0051】 The crease section 21 comprises a lower die 39 having an upper end recess and an upper die 38 having a lower end protrusion that fits into the recess. The upper die 38 is connected to a crease drive unit 49, such as a motor, via a power transmission mechanism. That is, by lowering the upper die 38 with the driving force of the folding die drive unit 49, a crease is formed on the sheet S in the width direction W perpendicular to the transport direction F. 【0052】 The cutter section 22 extends in the width direction W and is equipped with a pair of opposing cutting blades 69. One cutting blade 69 is composed of an upper movable blade 71, and the other cutting blade 69 is composed of a lower fixed blade 73. The upper movable blade 71 contacts and separates from the lower fixed blade 73, cutting the sheet S in the width direction W perpendicular to the transport direction F. The upper movable blade 71 is connected to a cutting drive unit 50 such as a motor via a power transmission mechanism. 【0053】 The scrap collection unit 23 includes a storage box 54 and guides 59 and 60. The storage box 54 is formed in the shape of a rectangular parallelepiped with an opening at the top. The storage box 54 collects and stores the scraps J that are cut off and become unnecessary in the cutting unit 19. The guides 59 and 60 guide the scraps J that are cut off and fall in the cutting unit 19 to the storage box 54. 【0054】 [Stacker device 8] A stacker device 8 is provided at the downstream end of the conveying direction F of the processing device 7. The stacker device 8 loads the workpieces Q obtained by the processing in the processing unit 24. The stacker device 8 is provided with a loading section 83 that can load the workpieces Q in different positions on the loading surface. The loading section 83 is provided with a belt conveyor 86 that loads the workpieces Q onto a belt 85 that travels in a circular motion. The workpieces Q discharged by the conveying unit 18 are transported and loaded onto the belt conveyor 86. 【0055】 The belt conveyor 86 comprises an endless belt 85, conveyor rollers 87, and a conveyor drive unit 40. The conveyor rollers 87 are installed at predetermined distances from each other in the direction of discharge of the workpiece Q, which is the same direction as the conveying direction F of the sheet S, and the belt 85 is stretched across them. The length of the belt 85 in the width direction W is a predetermined length that is approximately the same as or slightly longer than the width direction W of the conveying path 5 through which the sheet S is conveyed, and multiple workpieces Q that are discharged in parallel in the width direction W can be placed on the belt 85. The conveyor drive unit 40 is electrically connected to the control unit 45, and the control unit 45 controls the amount of drive of the conveyor drive unit 40 so that the belt conveyor 86 is adjusted to travel at a predetermined speed. 【0056】 The stacker device 8 further includes a full-capacity detection unit 300 that detects when the stacker is full of workpieces Q. The full-capacity detection unit 300 is composed of an optical sensor or the like and detects when the amount of workpieces Q on the stacking section 83 exceeds the stacking capacity. 【0057】 A conveyor stacker may be attached to the discharge side of the processing device 7. The conveyor stacker is a device that slowly transports the shredded individual sheets discharged from the processing device 7 by a belt conveyor and stacks the individual sheets in an upright position at an angle on a stacker provided at the end of the conveyor belt. In addition, the conveying path 5 of the individual sheets by the belt conveyor is equipped with sorting guides for sorting and aligning the individual sheets. 【0058】 [Control Unit 45] The control unit 45 has a CPU and built-in memory such as RAM and ROM. The control unit 45 controls the operation of the entire processing apparatus 100. The control unit 45 acquires information from the tip sensor 31, laser sensor 32, and detection units 31-35, and controls the drive of the supply device 2, cutting device 3, cross conveyor device 4, processing device 7, stacker device 8, and transport unit 18 based on the processing information of the sheet S set by the operation panel 46 or reading unit 26, and processes the sheet S. 【0059】 The control unit 45's interface is electrically connected to the operation panel 46 and the reading unit 26. The operation panel 46 serves as both a setting unit and a display unit for setting various processing information, including information related to the cutting process of the sheet S. The reading unit 26 constitutes the setting unit. 【0060】 Furthermore, the control unit 45 controls the operation of the moving part 51 of the processing unit 24. When the processing positions in the width direction W by the processing members 29 of the sheet S that is conveyed first by the conveying unit 18 and the subsequent sheet S are different, the control unit 45 processes the subsequent S sheet using the processing member 29 that minimizes the distance traveled from the processing position of the sheet S that is conveyed first. 【0061】 Furthermore, the control unit 45 can perform standby control to process the subsequent sheet S while keeping a processing member 29, whose processing position in the width direction W of a sheet S being transported further behind the subsequent sheet S is within a predetermined range from the processing position of the preceding sheet S, within a predetermined range from the position where the preceding sheet S has been processed. In addition, if the processing position of the preceding sheet S is within a predetermined value from the position of the side edge of the subsequent sheet S in the transport path 5, the control unit 45 can perform avoidance control to move a processing member 29 located within a predetermined value from the side edge of the subsequent sheet S to an avoidance position, which is moved by a predetermined amount away from the subsequent sheet S from the standby position where it is waiting within a predetermined range from the processing position of the preceding sheet S, and process the subsequent sheet S. 【0062】 Furthermore, the control unit 45 can perform movement control to move the processed member 29 that has processed the preceding sheet S to the processing position of the following sheet S, and process the following sheet S, if the processing positions of the preceding sheet S and the following sheet S are different, and the processing position of the sheet S further behind the following sheet S is within a predetermined range from the processing position of the preceding sheet S. The control unit 45 can also control whether to perform the standby control or the movement control based on the user's instructions. 【0063】 Furthermore, the control unit 45 can control the guide movement unit 283 so that the guide 28 removes the scraps Ja generated at the side edges of the sheet S when the sheet S is cut by the slitter 36 from the transport path 5. 【0064】 [Workpiece arrangement pattern on sheet S] Figure 4 is a plan view showing an example of an arrangement pattern of workpieces Q on a sheet S. The arrangement pattern of workpieces Q shown in this figure is designed to produce three crease-free workpieces Q1-Q3 from a single sheet S1. The three workpieces Q1-Q3 may be the same size and shape, or they may be different. When the shape and size of the workpieces Q1-Q3 are the same or nearly the same, the multiple processing positions formed along the transport direction F of the sheets S2 and S3, which are transported alternately back and forth, often fall within a predetermined range. 【0065】 First, the sheet S1, which is transported in the first direction A, is cut along the second direction B, which is perpendicular to the first direction A, at a position C1 that is one-third of the way from the leading edge Sf of the sheet S1 in the first direction A, which is the longitudinal direction of the sheet S1. 【0066】 Sheet S1 is cut into two sheets, Sheet S2 and Sheet S3. The conveying direction of Sheets S2 and S3 is changed to the second direction B by the cross conveyor device 4, and Sheet S2 and Sheet S3 are conveyed one by one to the processing device 7. 【0067】 Next, the sheet S2, which is transported in the second direction B, is cut along the transport direction F by two cutting lines D1 and D2 parallel to the second direction B, which is the transport direction F of the transport unit 18 of the processing device 7. Then, it is sequentially cut along the width direction W perpendicular to the transport direction F by cutting lines E1 and E2. After that, the sheet S3 is transported in the transport direction F. The sheet S3 is cut along the transport direction F by four cutting lines D3-D6 parallel to the transport direction F. Then, it is sequentially cut along the width direction W perpendicular to the transport direction F by cutting lines E3 and E4. 【0068】 When multiple sheets S1 are processed consecutively, sheets S2 and S3 are transported to the processing device 7 alternately and continuously. That is, for example, sheet S3 is transported first, followed by sheet S2. Sheet S3 is then transported even further behind sheet S2. 【0069】 Figure 5 shows the flow of the control unit 45. In the processing process shown in Figure 4, when alternatingly processing sheets S2 and S3 along the transport direction F of the transport unit 18 of the processing apparatus 7, the control unit 45 controls the moving unit 51 and determines which processing member 29 to move to which position in the width direction W to process the sheet S. In this first embodiment, a pair of left and right slitters 36, which are the processing members 29, are arranged in three rows along the transport direction F. Therefore, the control unit 45 determines which of the six slitters 36 to place at which position in the width direction W. 【0070】 In step 1 of Figure 5, a job is constructed for the arrangement of the processed members 29 in the transport path 5 based on the arrangement pattern of the workpieces Q on the sheet S1. In the processing of sheet S1 shown in Figure 4, the sheet S2 that is transported first has two cutting lines D1 and D2 set. The subsequent sheet S3 has four cutting lines D3 to D6 set. The control unit 45 generates two types of jobs A and B for the sheet S2 and the subsequent sheet S3 that are transported first by the transport unit 18, with different cutting positions of the slitter 36 as the processing position in the width direction W using the slitter 36 as the processed member 29. 【0071】 Figure 6 illustrates the arrangement of the slitter 36 as a processing member 29 in Job A. Job A is a processing operation along the transport direction F of the sheet S2. The sheet S2 has two cutting lines D1 and D2 set along the transport direction F of the processing device 7. As shown in Figure 6, in order to process the sheet S2, a pair of left and right slitters 361 and 362 of the first unit 20a are used as processing members 29. 【0072】 The distance of the cutting line D1 from the reference line G is L1. The reference line G is a reference line for determining the position of the processed member 29 in the width direction W. The reference line G can be set freely, but for example, it can be the same position in the width direction W of the transport path 5 inside the processing device 7 as the guide wall 402 and guide plate 68 of the cross conveyor device 4. This is the position of the left edge SL of the sheet S when the sheet S is transported by the transport unit 18 in the processing device 7. The left slitter 361 in Figure 6 of the first unit 20a is moved by the moving unit 51 to a position where the length from the reference line G is L1 when processing the sheet S2. In job A, the slitter 361 forms a cutting line D1 of the sheet S2 with a length of L1 from the side edge SL. 【0073】 The distance of the cutting line D2 from the reference line G is L2. The slitter 362 on the right side in Figure 6 of the first unit 20a is moved by the moving part 51 to a position where its length from the reference line G is L2. In job A, the slitter 362 forms the cutting line D2 at a position where its length from the left edge SL of the sheet S2 is L2. 【0074】 In Job A, since the slitters 361 and 362 of the first unit 20a are used, the scraps J generated by cutting are removed from the transport path 5 by a guide 55 that is installed to the side of the slitter 36 and moves in the width direction W together with the slitter 36. In Job A, the slitters 363-366 of the second unit 20b and the third unit 20c, and the guide 28 of the downstream scrap removal mechanism 27 are moved to positions outside the transport path 5 by the moving part 51 and the guide moving part 283, respectively, and put into standby position. 【0075】 Figure 7 illustrates the arrangement of the slitter 36 as a processed material 29 in Job B. Job B is a processing operation along the conveying direction F of the sheet S3. The sheet S3 has four cutting lines D3-D4 set along the conveying direction F. To process the sheet S3, the left and right pair of slitters 361, 362 of the first unit 20a, the left slitter 363 of the second unit 20b, and the left slitter 364 of the third unit 20c are used. 【0076】 The scraps JL generated at the left edge SL and the scraps JR at the right edge SR of sheet S2 and sheet S3 are both removed from the transport path 5 by the guide 55 provided on the slitter 36 of the first unit 20a. Therefore, the cutting lines D1, D2, D3, and D6 set near the left and right edges SL and SR of both sheet S2 and sheet S3 are formed using the slitters 361 and 362 of the first unit 20a. 【0077】 In Figures 6 and 7, the left slitter 361 of the first unit 20a is moved by the moving unit 51 in jobs A and B from the reference line G, which is the formation position of cutting lines D1 and D3, to positions L1 and L3, respectively. Then, in Figures 6 and 7, the right slitter 362 of the first unit 20a is moved by the moving unit 51 in jobs A and B from the reference line G, which is the formation position of cutting lines D2 and D6, to positions L2 and L6. 【0078】 In contrast, the left slitter 363 in Figure 7 of the second unit 20b and the left slitter 36 of the third unit 20c form cutting lines D4 and D5 in the middle of the sheet S3. The left slitter 363 in Figure 7 of the second unit 20b is moved by the moving part 51 from the reference line G, which is the position where cutting line D4 is formed, to the position L4. The left slitter 365 of the third unit 20c is moved by the moving part 51 from the reference line G, which is the position where cutting line D5 is formed, to the position L5. 【0079】 The left guide 281 of the scrap removal mechanism 27 is moved by the guide movement unit 283 to a position between L3 and L4 from the reference line G. The guide 281 guides the scraps Jb between the workpieces Q2 and Q3 downwards in the transport path 5 and removes them from the transport path 5. 【0080】 The right-side slitters 364 and 366 of both the second unit 20b and the third unit 20c, which are not used in Job B, and the right-side guide 282 of the scrap removal mechanism 27 are moved to a position outside the transport path 5 by the moving part 51 and the guide moving part 283, respectively. 【0081】 In step 2 of Figure 5, the constructed jobs A and B are sorted in descending order by the number of processed parts 29 required. The number of slitters 36 used in job A is 2. The number of slitters 36 used in job B is 4. In this case, when jobs A and B are sorted in descending order, job B is ranked first and job A is ranked second. 【0082】 In Step 3, Job B, which is determined to require the largest number of slitter 36s, is designated as the reference job. This reference job B is designated as Job 1. The other jobs are then numbered in descending order as Job 2, Job 3, Job 4, etc. Therefore, Job A becomes Job 2. 【0083】 In step 4, determine whether the arrangement of the workpieces 29 in job 2 can be swapped based on job 1. Whether the arrangement of the workpieces 29 can be swapped can be determined, for example, as follows: 【0084】 When the processing member 29 is a slitter 36, in the slitter section 20, the rotating drive blade 58 and the driven blade 59 are pressed together and rub against each other as the sheet S passes through the pressure contact section 29. In the uppermost first unit 20a, cutting lines D for cutting the right and left edges of the sheet S can be formed. 【0085】 As shown in Figure 8(A), when the sheet S is cut by the slitter 36 and separated into workpiece Q and scraps J, it is preferable that in the width direction W, the lower cutting blade 36b is located on the same side as the workpiece Q with respect to the cutting line D, and the upper cutting blade 36a is located on the same side as the scraps J. By positioning the lower cutting blade 36b on the same side as the workpiece Q in the width direction W, the cutting line D is formed and the separated workpiece Q can be supported from below by the lower cutting blade 36b. Therefore, it can be properly transported downstream. On the other hand, by positioning the upper cutting blade 36a on the same side as the scraps J in the width direction W, the scraps J separated from the sheet S can be guided downward by the upper cutting blade 36a. 【0086】 There are four possible combinations of two of the six slitters 361 to 366 installed in the slitting section 20 to form the cutting line D for separating the sheet S into the workpiece Q and the scraps J, as shown in Figure 8 (A) to (D). 【0087】 In Figures (A) and (B), the upper cutting blade 36a of the conveyor path 5 of the left slitter 36L is located to the right of the cutting line D. In Figures (C) and (D), the upper cutting blade 36a of the conveyor path 5 of the left slitter 36L is located to the left of the cutting line D. On the other hand, in Figures (A) and (C), the upper cutting blade 36a of the conveyor path 5 of the right slitter 36R is located to the left of the cutting line D. In Figures (B) and (D), the upper cutting blade 36a of the conveyor path 5 of the right slitter 36R is located to the right of the cutting line D. 【0088】 When a sheet S is cut by the upper cutting blade 36a of the left slitter 36L and the right slitter 36R, and unwanted scraps J are generated between the two slitters 36L and 36R, it is preferable that the upper cutting blade 36a is not positioned outside the lower cutting blade 36b with respect to the scraps J. Furthermore, with respect to the cutting line D that separates the workpiece Q and the scraps J, it is preferable that at least one of the upper cutting blades 36a is positioned on the side where the scraps J are generated, and the lower cutting blade 36b is positioned on the side where the workpiece Q is generated. 【0089】 Specifically, as shown in Figure 8(D), the configuration in which the upper cutting blade 36a that grips the generated scraps J is positioned on both the left and right sides of each cutting line D on the side where the workpiece Q is generated is not set. In this way, if switching the arrangement of the slitter 36 results in a configuration in which the upper cutting blade 36a that grips the generated scraps J is positioned on both the left and right sides of each cutting line D on the side where the workpiece Q is generated, the control unit 45 determines that the arrangement of the slitter 36 cannot be changed. 【0090】 In response, the control unit 45 determines that the arrangement of the slitter 36 can be switched in the combinations shown in (A), (B), and (C) of the figure. In (A) of the figure, the upper cutting blade 36a is positioned inside the lower cutting blade 36b with respect to the scraps J it generates. In (B) and (C) of the figure, one upper cutting blade 36a is positioned inside the lower cutting blade 36b with respect to the scraps J it generates, and the other upper cutting blade 36a is positioned outside the lower cutting blade 36b with respect to the scraps J it generates. 【0091】 As shown in Figure (B), the upper cutting blade 36a is installed to the right of the pressure contact portion 343 of the upper and lower cutting blades 36a and 36b in the slitter 361 on the right side of the upstream first unit 20a, the slitter 364 on the left side of the central second unit 20b, and the slitter 365 on the right side of the downstream third unit 20c. These slitters 36 are interchangeable. 【0092】 As shown in Figure (C), the upper cutting blade 36a is installed to the left of the pressure contact portion 343 of the upper and lower cutting blades 36a and 36b in the slitter 362 on the left side of the upstream first unit 20a, the slitter 363 on the right side of the central second unit 20b, and the slitter 366 on the left side of the downstream third unit 20c. These slitters 36 can also be switched between each other. 【0093】 As shown in Figure 9, the first unit 20a at the uppermost position forms the outermost cutting line D of the sheet S, the second unit 20b in the center forms a cutting line D one position inward from the first unit 20a, and the third unit 20c at the lowermost position forms the cutting line D closest to the center of the sheet S. As a result, all the upper cutting blades 36a are positioned on the side of the pressure contact section 343 that forms the cutting lines D where the scraps Ja and Jb are generated, and all the lower cutting blades 36b are positioned on the side of the pressure contact section 343 where the workpiece Q is generated. Therefore, the partially processed sheet S can be properly transported downstream while allowing the scraps J to fall properly. 【0094】 In the scrap removal mechanism 27, the scraps Jb cut from the sheet S by the central second unit 20b and the downstream third unit 20c of the slitter section 20 are moved downward by the guide 28 to the scrap collection section 23 below and stored in the storage box 54. 【0095】 When the processed member 29 is a crease blade (not shown) equipped with a rotary concave blade (not shown) and a convex blade (not shown) that form a crease along the conveying direction F, it is determined that all such crease blades are interchangeable with other corresponding crease blades. This is because, unlike a slitter 36, the shapes of the concave and convex blades do not differ on the left and right sides with respect to the processing line of the sheet S. For example, the crease blade may have a convex blade above the conveying path 5 and a crease blade below the conveying path 5. Alternatively, the concave blade may be installed above the conveying path 5 and the convex blade below the conveying path 5. 【0096】 Even when the processing member 29 is a pair of upper and lower perforating blades (not shown) equipped with a rotary perforating blade (not shown) and a receiving blade (not shown) for the perforating blade, the arrangement of the processing member 29 in step 4 of Figure 5 can be rearranged. This is because the rotary perforating blade and receiving blade are symmetrical with respect to the processing line of the sheet S, similar to the crease blade. When the processing member 29 is a half-cut blade (not shown) that cuts a portion of the sheet S in the thickness direction, it is possible to determine that the arrangement of all processing members 29 can be rearranged. 【0097】 If it is determined in step 4 of Figure 5 that the workpiece 29 can be replaced, the process proceeds to step 5, where job 1 is used as the reference job, and control is performed to swap the positions of the workpiece 29 in the other jobs 2, 3, and 4. 【0098】 If replacing the slitter 36 results in a situation like Figure 8(D), and it is determined in step 4 that the slitter 36 cannot be replaced, the process proceeds to step 6, where control is implemented to prevent the replacement of the slitter 36. 【0099】 Furthermore, if, for example, the user inputs and sets instructions to not change the arrangement of the processed parts 29, step 4 is not met, and the system proceeds to step 6. 【0100】 Thus, the control unit 45 can perform movement control to move the processed member 29, which has been processed on either sheet S2 or sheet S3, from the processing position of sheet S2 or sheet S3 to the other processing position, when the processing positions of sheet S2 and sheet S3 are different, and the processing position of the subsequent sheet S2 or sheet S3 is the same as that of either sheet S2 or S3 that is transported earlier. 【0101】 In this case, the user can choose whether or not to perform standby control to keep the processed member 29 in standby position, improving convenience. 【0102】 Figures 10 and 11 show a detailed flow when the arrangement of the slitter 36 as the processed material 29 in step 5 of Figure 5 is changed. The arrangement of the slitter 36 in the reference job 1 is a processing operation along the conveying direction F of the sheet S3 shown in Figure 7. With respect to the arrangement of slitters 361, 362, 363, and 365 in job 1 shown in Figure 7, it is sequentially decided which processing position to place the slitters 361 and 362 of job 2 shown in Figure 6 at and whether to replace them with other slitters. Then, it is decided whether to switch the left and right pair of slitters 361 and 362 of the first unit 20a used in job 2 to slitters 363, 364, 365, and 366 of any of the other units 20b and 20c, and if a switch is made, it is decided where in the width direction W the switched slitter 36 will be positioned. 【0103】 In step 11 of Figure 10, the multiple slitters 361, 362, 363, and 365 whose positions in the width direction W have been determined in Job 1 and Job 2 are numbered in order of increasing length from the reference line G. 【0104】 In step 12, set job number N to 2. In step 13, set i=0. i is set to consider whether to switch the slitters 36 in order, starting with the slitter 36 located at the shortest distance from the reference line G. 【0105】 In step 14, it is determined whether the identification number of the first slitter 361 of Job 2, which is L1 in length from the reference line G, is the same as the identification number of the first slitter 361 of Job 1, which is the shortest in length from the reference line G. All slitters 36 installed in the slitter section 20 are pre-assigned identification numbers, for example, as shown in Figure 12. Figure 12 shows the case where the identification numbers are 1 for the left slitter 36 of the first unit 20a, 2 for the right slitter 36, 3 for the left slitter 36 of the second unit 20b, 4 for the right slitter 36, 5 for the left slitter 36 of the third unit 20c, and 6 for the right slitter 36. 【0106】 The identification number of the first slitter 36 in Job 2 is 1, which is the same as the identification number 1 of the first slitter 36 in Job 1. In this case, since both Job 1 and Job 2 use the same slitter 36 with identification number 1, there is no need to swap them. At this point, step 14 is satisfied and the process proceeds to step 17. 【0107】 Here, when lengths L1 and L3 are the same from the reference line G, the width of the scraps Ja at the left edge SL of sheet S2 and sheet S3 will be the same. In this case, the position of the slitter 361 on the left side of the first unit 20a is not moved between sheet S2 and sheet S3, and the processing continues in the same position. 【0108】 On the other hand, when lengths L1 and L3 from the reference line G are different, the widthwise length W of the scraps Ja at the left edge SL of sheet S2 and sheet S3 will be different. In this case, the position of the left slitter 361 of the first unit 20a in the widthwise direction W is moved by the moving unit 51 from position L1 to position L3 after the processing of the preceding sheet S2 and before the processing of the subsequent sheet S3. At this time, the slitter 361 is moved by the difference between L1 and L3. 【0109】 Furthermore, when multiple sheets S1 having the same arrangement pattern are processed consecutively, the processing device 7 transports sheet S3 first, followed by sheet S2. In this case, after processing the preceding sheet S3 and before processing the subsequent sheet S2, the position of the slitter 36 is moved from position L3 to position L1. 【0110】 Thus, when the processing positions L1 and L3 in the width direction W by the slitter 36, which is a processing member 29 for the sheet S2 that is conveyed first by the transport unit 18 and the subsequent sheet S3, or for the preceding sheet S3 and the subsequent sheet S2, are different, the control unit 45 processes the cutting line D3 of the sheet S3 using the slitter 361, which is a processing member 29 that minimizes the distance traveled from the processing position of the sheet S2. 【0111】 This reduces the time required for the slitter 361 to move in the width direction W between sheet S2 and sheet S3. It also reduces the time required from the start of processing of sheet S1 until it is discharged to the stacker device 8. 【0112】 In step 17, increment i. Now, consider whether to switch the second slitter 36 from the reference side to another slitter 36, which is the next slitter 36, from slitter 362 of job 2. 【0113】 Proceed to step 18 and determine if the value of i is less than the number of slitters 36 used in job 2. In step 18, check whether it has been decided which slitter 36 to use for all slitters 36 used in job 2. Since job 2 uses two slitters 36, i=1, which is less than the number of slitters 36 in job 2 (2), thus satisfying step 18. In other words, at this point, it has only been decided which slitter 36 to use for the first slitter 361, which has the shortest distance from the reference line G. In this case, step 18 is satisfied, and return to step 14. 【0114】 In step 14, determine whether the identification number of the second slitter 36 in Job 2, whose length from the reference line G is L2 as shown in Figure 6, is the same as the identification number of the second slitter in Job 1 as shown in Figure 6. In Job 1, the identification number of the second slitter 36 is 3, and in Job 2, the identification number is 2. In this case, the two are different, so step 14 is not satisfied, and proceed to step 15. 【0115】 In step 15, determine if the second slitter 36 with identification number 2 in job 2 can be swapped with the slitter 36 with identification number 3 in job 1. If they cannot be swapped, step 15 is not met, and proceed to step 26. In step 26, leave the position of slitter 36 unchanged from the setting in job 2. 【0116】 If identification numbers 2 and 3 are interchangeable, step 15 is met and the process proceeds to step 16. As shown in Figure 9, the slitter 362 for identification number 2 and the slitter 363 for identification number 3 have the lower cutting blade 36b positioned on the left and the upper cutting blade 36a positioned on the right with respect to the cutting line D. In this case, even if the slitters 362 and 363 for identification numbers 2 and 3 are interchangeable, the workpiece Q can be properly transported downstream, and the scraps J can be removed from the transport path 5 and dropped. 【0117】 Thus, if it is determined that identification number 2 and identification number 3 are interchangeable, in step 16, the second slitter 36 from the side of the reference line G of job 2 is set to change from identification number 2 to identification number 3. 【0118】 In this way, by swapping slitter 362 and slitter 363, slitter 363 can be used to process the cutting line D2 of sheet S2. Figure 13 shows which of the slitters 361-364 is used to cut the cutting lines D1-D6 of sheets S2 and S3, which are transported alternately in the front-back and back-to-back directions. 【0119】 When the cutting positions in the width direction W of sheets S2 and S3, which are transported back and forth by the transport unit 18, as in job A and job B, are different, such as cutting lines D1 and D2 and cutting lines D3-D6, the control unit 45 can use the slitter 363 that forms the cutting line D4 of sheet S3 to form the cutting line D2 of sheet S2, which minimizes the distance traveled from this cutting position. 【0120】 Therefore, when jobs A and B are performed alternately, after cutting the sheet S2, the slitter 362 can be processed without moving in the width direction W from the position where the cutting line D2 is formed with a length L2 from the reference line G to the position where the cutting line D6 is formed with a length L4 from the reference line G, by the moving part 51. The slitter 263 on the left side of the second unit 20b can be used to form the cutting line D2 of the sheet S2. 【0121】 Then, the slitter 363 on the left side of the second unit 20b, which formed the second cutting line D2 of sheet S2, is used to form the fourth cutting line D4 of the subsequent sheet S3. After the cutting line D4 is formed, the slitter 263 on the left side of the second unit 20b can be used again to form the cutting line D2 of sheet S2. Therefore, sheet S2 can be processed without the slitter 362 moving in the width direction W from the position where the cutting line D6, which is L4 from the reference line G, is formed, to the position where the cutting line D2, which is L2 from the reference line G of sheet S2, is formed, by the moving part 51. As a result, the time required for the movement of the slitter 36 can be shortened. Sheet S1 can be processed faster. 【0122】 In particular, when processing multiple sheets of sheet S1 shown in Figure 4 consecutively using the processing device 100, the sheet S1 is cut along the cutting line C1 in the upstream cutting device 3, and then jobs A and B are repeatedly performed alternately in the processing device 7. At this time, the slitter 362 must be moved each time between sheets S2 and S3 which are transported one after the other, which can be avoided as it would result in a very slow processing speed. 【0123】 Here, when L2 and L4 are the same length, the lengths from the reference line G to the cutting line D2 of sheet S2 and the cutting line D4 of sheet S3 are the same. In this case, the slitter 363 on the left side of the second unit 20b is not moved in the width direction W, but maintains the same position and continuously processes both sheet S2 and sheet S3. 【0124】 On the other hand, when the lengths of L2 and L4 are different, the position of the left slitter 363 of the second unit 20b in the width direction W is moved by the difference between L2 and L4 in the width direction W when processing sheet S2 and when processing sheet S3. 【0125】 Proceed to step 17 and increment i. In step 18, determine if the value of i is less than the number of slitters 36 used in job 2. At this point, the value of i is 2, and the number of slitters used in job 2 is 2. Therefore, step 18 is not satisfied, and proceed to step 19 in Figure 11. 【0126】 In step 19, we determine if the value of i is greater than or equal to the number of slitter 36 used in job 1. At this point, the value of i is 2, and the number of slitter 36 used in job 1 is 4. Therefore, step 19 is not met, and we proceed to step 20. 【0127】 In step 20, the slitter 365, which is the third from the reference line G of job 1 and has a length L5, is set to wait in a predetermined waiting position within a set range from the position where sheet S3 was previously transported and cut in job 1, while cutting the subsequent sheet S2. 【0128】 Furthermore, the processing device 7 determines whether the processing position of the third cutting line D5 from the reference line G of the sheet S3 being transported first is within a predetermined value from the position of the right edge SR in Figure 13 on the transport path 5 of the subsequent sheet S2. If the difference between the formation position of the third cutting line D5 from the reference line G of sheet S3 and the transport position of the right edge SR of sheet S2 in the width direction W is within a predetermined value, the slitter 365, which is located within a predetermined value from the side edge Sw of the subsequent sheet S2, is moved by a predetermined amount α to the right in Figure 13, away from the subsequent sheet S2, from its waiting position where it waits within a predetermined range from the formation position of the cutting line D5 of the sheet S3 being transported first, and is set to perform avoidance control to process the subsequent sheet S2. 【0129】 This prevents the slitter 365, as a processing member 29, from remaining within a predetermined distance from the right edge SR of the conveyed sheet S2 when processing the sheet S2. If the slitter 365 is positioned at the right edge SR of the sheet S2, very short scraps J with a width W of less than or equal to a predetermined value may be generated. Such scraps J are difficult to remove from the conveying path 5 by their own weight or by the guides 55, 28. By moving the slitter 365 away from the sheet S2 during the processing of the sheet S2, it is possible to avoid the narrow scraps J remaining near the drive blade 58 and driven blade 59 or in the conveying path 5, which could cause problems during cutting or paper jams. 【0130】 With the slitter 365 in the avoidance position, after the sheet S2 has been processed, and before the subsequent sheet S3 is transported to the slitter 365 installation position, the slitter 365 is moved back to its original standby position. 【0131】 In step 21, increment i. In step 22, determine if the value of i is less than the number of 36 slitters used in job 1. At this point, the value of i is 3, and the number of slitters used in job 1 is 4, so step 22 is satisfied and proceed to step 23. 【0132】 In step 23, the slitter 362 that forms the cutting line D6 of sheet S3, which is the fourth slitter from the reference line, is set to wait at the position where the cutting line D6 of sheet S3 is formed when sheet S2 is being processed. As a result, the slitter 362 on the right side of the first unit 20a waits in the waiting position without performing any processing when sheet S2 is being processed. 【0133】 In other words, when multiple sheets S with the arrangement pattern shown in Figure 4 are processed consecutively by the processing device 100, first, in the upstream cutting device 3, each sheet S is cut along the cutting line C, dividing it into sheets S2 and sheets S3. Then, the two types of sheets S2 and sheets S3, which have different lengths in the first direction A, are alternately transported to the downstream processing device 7. 【0134】 When sheet S3 is transported first, followed by sheet S2, and then sheet S3 is transported further back, the control unit 45 performs standby control to process the following sheet S2 while keeping the slitter 362, which is a processing member 29 whose processing position in the width direction W of sheet S3 is within a predetermined range from the processing position of the sheet S3 that is transported first, waiting within a predetermined range from the position where the sheet S3 that was transported first has been processed. 【0135】 As a result, the position of the slitter 362 in the width direction W is moved between the position L2 from the reference line G and the position L6 from the reference line G each time sheets S2 and S3 are transported alternately, and it is possible to keep it at the position L6 from the reference line G without having to swap them. The time required to move the slitter 362 in the width direction W can be reduced. Processing speed is increased. 【0136】 Therefore, when different types of jobs, such as Job A and Job B, are repeatedly executed, the control unit 45 controls the position of the slitter 36, which is the processing member 29 that processes the sheet S3, to be limited to movement within a predetermined range, using the slitter 36 as the processing member 29 that minimizes the distance traveled from the processing position of the sheet S3. This makes it possible to shorten the processing time. 【0137】 Return to step 21 from step 23. In step 21, increment i. In step 22, determine if the value of i is less than the number of 36 slitters used in job 1. At this point, the value of i is 4, and the number of slitters used in job 1 is 4, so step 22 is not satisfied. In this case, proceed to step 24. 【0138】 In step 24, increment N. Proceed to step 25 and determine whether the value of N is less than the number of valid jobs. If there are three or more types of jobs, satisfy step 25 and return to step 13 as shown in Figure 10. Perform steps 13 through 25 again to determine, for another job, whether to switch all the workpieces 29 used in job 1 to other workpieces 29 for the other job, or to have them wait within a predetermined range from the workpiece position. Then, if necessary, set the other job to switch the workpieces 29 to other workpieces 29, and to have them wait within a predetermined range from the workpiece position of job 1. 【0139】 In the machining process for sheet S1 shown in Figure 4, at step 25, the value of N is 3, and the number of valid jobs is 2. Therefore, step 25 is not met, and the process terminates. 【0140】 [Effect] The operation of the processing device 100 is described below. The user inputs various processing information via the control panel 46. Alternatively, instead of manual input, a job may be generated separately on a PC and loaded. A job pre-generated on a PC and stored in memory may also be recalled. Furthermore, processing information can be automatically input by reading the information printed on the sheet S using the reading unit 26. 【0141】 The user places a sheet S on the paper feed tray 21 shown in Figure 1. The sheet S is fed out by the air paper feed unit. When the leading edge of the sheet S reaches the leading edge sensor 31 of the cutting device 3, the sheet S1 is transported by the transport roller pair 39. 【0142】 In the cutting device 3, the tip sensor 31 detects the inclination angle of the sheet S itself during transport with respect to the first direction A. Subsequently, the laser sensor 32 detects the inclination angle of the printed image formed on the sheet S with respect to the first direction A. In addition to the inclination angle of the printed image, the laser sensor 32 may also detect the inclination angle of the sheet S itself. 【0143】 The cutting device 3 adjusts the angle of the movable blade unit 34 of the cross-cut section based on the detected tilt angle of the printed image, so that appropriate cutting can be performed on the printed image, regardless of the tilt angle of the sheet S1 being conveyed. When the cutting position C1 along the second direction B of the sheet S1 reaches the cutting blade installation position, the conveyance of the sheet S1 is stopped and the sheet S1 is cut. After cutting, the sheet S1 is divided into sheet S2 and sheet S3. Sheets S2 and S3 are each discharged to the cross conveyor device 4 by the conveyor roller pair 39. 【0144】 The sheets S2 and S3, upon reaching the cross conveyor device 4, are transported in the second direction B along the guide wall 402. They then proceed to the processing device 7. 【0145】 In the slitter section 20 of the processing device 7, cutting lines D1 and D2 are formed on the sheet S2 by slitters 361 and 363 along the transport direction F of the transport section 18 of the processing device 7. When the position where the cutting lines E1 and E2 are formed on the sheet S2 reaches the position where the cutting blade 69 of the cutter section 22 is installed, transport by the transport section 18 is stopped. The upper movable blade 71 approaches the lower fixed blade 73, and cutting lines E1 and E2 are formed along the width direction W. 【0146】 In the slitter section 20 of the processing device 7, cutting lines D3, D4, D5, and D6 are formed on the sheet S3 by slitters 361, 363, 365, and 362, respectively, along the transport direction F of the transport section 18 of the processing device 7. When the cutting lines E1 and E2 formation positions of the sheet S3 reach the position where the cutting blades 69 of the cutter section 22 are installed, transport by the transport section 18 is stopped. The upper movable blade 71 approaches the lower fixed blade 73, and cutting lines E1 and E2 are formed along the width direction W. The processed products Q obtained by processing sheets S2 and S3 are discharged to the stacker device 8. 【0147】 (Second embodiment) Figure 14 is a plan view showing the workpiece arrangement pattern of sheet S4 according to the second embodiment. The processing apparatus 100 according to this second embodiment has the same mechanical configuration as the processing apparatus 100 according to the first embodiment. Furthermore, the control unit 45 of the processing apparatus 100 according to this second embodiment is controlled according to the same control flow as the control unit 45 according to the first embodiment. 【0148】 The sheet S4 in Figure 14 is designed to produce five crease-free workpieces Q4-Q8 from a single sheet S4. The size and shape of each of the five workpieces Q4-Q8 are approximately the same, but they may differ. 【0149】 In the cutting device 3, first, the sheet S4, which is transported in the first direction A, is cut along the second direction B, which is perpendicular to the first direction A, at a position C2 that is two-fifths of the way from the leading edge Sf of the sheet S4 in the first direction A, which is the longitudinal direction of the sheet S4. 【0150】 Sheet S4 is divided into two sheets, sheet S5 and sheet S6. Sheets S5 and S6 are transported one by one to the processing device 7 by the cross conveyor device 4, with the direction of transport of sheet S being changed to the second direction B. 【0151】 Next, the sheet S5, which is being transported in the second direction B, is cut along the transport direction F by four cutting lines D7-D10 parallel to the transport direction F of the transport unit 18 in the processing device 7. Then, it is sequentially cut along the width direction W perpendicular to the transport direction F by cutting lines E3 and E4. After that, the sheet S6 is transported in the transport direction F. The sheet S6 is cut along the transport direction F by six cutting lines D11-D16 parallel to the transport direction F. Then, it is sequentially cut along the width direction W intersecting the transport direction F by cutting lines E3 and E4. 【0152】 When processing the sheet S4 according to the second embodiment, similar to the first embodiment, the process is determined by moving each processing member 29 to a position in the width direction W and processing the sheet S4, according to the control flow shown in Figures 5, 10, and 11. 【0153】 In step 1 of Figure 5, a job is constructed for the arrangement of the processed material 29 in the transport path 5 based on the arrangement pattern of the workpieces Q4-Q8 in sheets S5 and S6. In the processing shown in Figure 14, sheet S5, which is transported first to the processing device 7, has four cutting lines D7-D10 set. The subsequent sheet S6 has six cutting lines D11-D16 set. The control unit 45 generates two types of jobs C and D for sheet S5, which is transported first by the transport unit 18, and the subsequent sheet S6, which have different cutting positions of the slitter 36 as the processing position in the width direction W using the slitter 36 as the processed material 29. 【0154】 Figure 15 illustrates the arrangement of the slitters 36 as processing members 29 in Job C. In Job C, four cutting lines D7-D10 are set along the transport direction F of the processing device 7, similar to the processing of Job A in the first embodiment shown in Figure 7. In order to process the sheet S5, the left and right pair of slitters 361 and 362 of the first unit 20a, the left slitter 363 of the second unit 20b, and the left slitter 365 of the third unit are used as processing members 29. 【0155】 Figure 16 illustrates the arrangement of the slitter 36 as a workpiece 29 in job D. In job D, six cutting lines D11-D16 are set along the transport direction F. To process the sheet S6, all slitters 361-366 of the 1st-3rd units 20a,-20c installed in the slitter section 20 are used. 【0156】 The cutting lines D11 and D16 near the left and right edges of sheet S6 are formed using slitters 361 and 362 of the first unit 20a, which have guides 55. The cutting lines D12 and D15 closer to the center of sheet S6 than the cutting lines D11 and D16 are formed using slitters 363 and 364 of the second unit 20b. The cutting lines D13 and D14 closest to the center of sheet S6 are formed by slitters 365 and 366 of the third unit 20c. 【0157】 The pair of left and right guides 28 of the scrap removal mechanism 27 are moved to positions between slitter 363 and slitter 365, and between slitter 366 and slitter 364. 【0158】 In step 2 of Figure 5, the constructed jobs C and D are sorted in descending order by the number of processed parts 29 required. The number of slitters 36 used in job C is 4, and the number of slitters used in job D is 6. In this case, when jobs C and D are sorted in descending order, job D is ranked first and job C is ranked second. 【0159】 In Step 3, Job D, which is determined to require the largest number of slitter 36s, will be designated as the baseline job. This baseline Job D will be designated as Job 1. The other job, Job C, will be designated as Job 2. 【0160】 In step 4, it is determined whether the arrangement of the workpiece 29 in job C, designated as job 2, can be swapped with other workpieces 29. If it is determined in step 4 that the workpiece 29 can be swapped, the process proceeds to step 5, where job 1 is used as the reference job and control is made to swap the arrangement of the workpiece 29 in the other job 2. If it is not possible to swap the workpiece 29 in step 4, the process proceeds to step 6 and terminates without swapping. 【0161】 In this second embodiment, when executing the control flow shown in Figures 10 and 11, in step 11 of Figure 10, the multiple slitters 361-366 whose positions in the width direction W have been determined in Job 1 and Job 2 are numbered in order of increasing length from the reference line G. 【0162】 In step 12, set job number N to 2. The arrangement of the slitter 36 in job D, which is designated as the reference job 1, is a processing operation along the conveying direction F of the sheet S6 shown in Figure 15. With respect to the arrangement of the slitter 36 in job 1 shown in Figure 15, the processing positions of the slitter 36 in job C, which is designated as job 2 and shown in Figure 16, are determined sequentially. In step 13, set i=0. 【0163】 In step 14, determine whether the identification number of the first slitter 361 in job 2 is the same as the identification number of the first slitter 361 in job 1. 【0164】 The identification number of the first slitter 361 in Job 2 is 1, which is the same as the identification number 1 of the first slitter 361 in Job 1. In this case, since both Job 1 and Job 2 use the same slitter 361 with identification number 1, there is no need to swap them. At this point, step 14 is satisfied and the process proceeds to step 17. 【0165】 In step 17, increment i. Proceed to step 18 and determine if the value of i is less than the number of slitter 36 used in job 2. Job 1 uses 6 slitter 36, so i=1, which is less than the 6 slitters used in job 1. In this case, step 18 is satisfied, and return to step 14. 【0166】 In step 14, determine whether the identification number of the second slitter 36 in job 2, shown in Figure 15, is the same as the identification number of the second slitter 36 in job 1, shown in Figure 16. In job 1, the identification number of the second slitter 36 is 3, and the identification number in job 2 is also 3. Therefore, they are the same. In this case, just like the first slitter 361, step 14 is satisfied and proceed to step 17. In step 17, increment i. Proceed to step 18 and determine whether i is less than the number 4 of the slitter 36 in job 2. 【0167】 In step 18, i is 2 at this point. This is less than the number 4 for slitter 36 in job 2. Therefore, step 18 is satisfied, and we return to step 14. 【0168】 In step 14, determine if the identification number of the third processed part 29 in job 2 is the same as the identification number of the third slitter 36 in job 1. Since the third slitter 36 is 5 in both job 1 and job 2, step 14 is satisfied. In step 17, increment i. In step 18, determine if i is less than the number of slitters 36 in job 2, which is 4. At this point, the value of i is 3. The total number of slitters 36 in job 2 is 4. In this case, step 18 is satisfied, and return to step 14. 【0169】 In step 14, the fourth identification number for job 2 is 2, and the identification number for the fourth slitter 36 in job 1 is 6. In this case, the two are different, so step 14 is not satisfied, and we proceed to step 15. In step 15, we determine whether the fourth slitter 362 with identification number 2 in job 2 can be swapped with the slitter 36 with identification number 6 in job 1. 【0170】 As shown in Figure 9, in both slitter 362 (identification number 2) and slitter 366 (identification number 6), the lower cutting blade 36b is positioned on the left side and the upper cutting blade 36a is positioned on the right side of the pressure contact portion 343 of the upper and lower cutting blades 36a and 36b. In this case, slitter 362 and slitter 366 can be interchanged. Since step 15 is satisfied, proceed to step 16. 【0171】 In step 16, the fourth slitter 36 from the side of the reference line G of job 2 is set to change from identification number 2 to identification number 6. By swapping slitter 362 and slitter 366, slitter 366 is used to process the cutting line D10 of sheet S5. When sheet S5 and sheet S6 are transported alternately, the cutting line 10 near the right edge SR of sheet S5 is cut using slitter 366. The scraps Ja generated by slitter 366 are removed from the transport path 5 by either the left or right guide 28 of the scrap removal mechanism 27. 【0172】 Instead of moving the slitter 362 in the width direction W to form the cutting line D10 on sheet S5, by using the slitter 366 that forms the cutting line D14 on sheet S6, when processing sheets S4 and S5 with different cutting positions, sheet S5 can be processed using the slitter 366 on the right side of the third unit 20c, which is the processing member 29 that minimizes the movement distance of the slitter 36 in the width direction W. Compared to using the slitter 362 on the right side of the first unit 20a, the processing time for sheet S4 can be shortened. 【0173】 Proceed to step 17 in Figure 10 and increment i. In step 18, determine if the value of i is less than the number of slitters 36 used in job 2. At this point, the value of i is 4, and the number of slitters used in job 2 is 4. Therefore, step 18 is not satisfied, and proceed to step 19 in Figure 11. 【0174】 In step 19, we determine if the value of i is greater than or equal to the number of slitter 36 used in job 1. At this point, the value of i is 4, and the number of slitter 36 used in job 1 is 6. Therefore, step 19 is not met, and we proceed to step 20. 【0175】 In step 20, the length L15 from the reference line G in job 1 is set so that the fifth slitter 364 is positioned in the standby position during job 1. Then, it is determined whether the position of the right edge SR of the sheet S5 being transported along the transport path 5 is within a predetermined value from the reference line G of job 1 to the processing position of the fifth slitter 364. If it is within the predetermined value, the length Sw in the width direction W of the sheet S5 is within a predetermined value for the length D15 from the reference line G of job 1 to the processing position of the fifth slitter 364. The transport position of the right edge SR of the sheet S5 in the transport path 5 is compared with the length L15 from the reference line G to the cutting line D15 of the fifth slitter 364 of job 1. If the difference between the two is within a predetermined value, the fifth slitter 364, which performs avoidance control in the processing of job 2, is set to move to a position on the right side of the diagram that is a predetermined amount longer than the length Sw in the width direction W of the sheet S5. This avoidance control is performed by moving the fifth slitter 364, which waits within a predetermined range from the processing position of the preceding sheet, to an avoidance position moved by a predetermined amount away from the subsequent sheet, and then processing the subsequent sheet. 【0176】 Return to step 21 from step 23 and increment i. In step 22, determine if the value of i is less than the number of 36 slitters used in job 1. At this point, the value of i is 5, and the number of slitters used in job 1 is 6, so step 22 is satisfied and proceed to step 23. 【0177】 In step 23, the slitter 362 that forms the cutting line D16 of sheet S6, which is the 6th slitter from the reference line, is set to wait at a position in the width direction W for forming the cutting line D16 of sheet S6 when sheet S5 is being processed. As a result, the slitter 362 on the left side of the first unit 20a waits in the waiting position without performing any processing when sheet S5 is being processed. This makes it possible to shorten the processing time compared to when the slitter 362 is moved and processing is performed. 【0178】 Return to step 21 from step 23. In step 21, increment i. In step 22, determine if the value of i is less than the number of 36 slitters used in job 1. At this point, the value of i is 7, and the number of slitters used in job 1 is 6, so step 22 is not satisfied. In this case, proceed to step 24. 【0179】 In step 24, N is incremented. Proceed to step 25 and determine whether the value of N is less than the number of active jobs. Sheet S4 shown in Figure 16 has two jobs running, Job C and Job D, so the number of active jobs is 2. On the other hand, the value of N is 3, so step 25 is not met and the process ends. 【0180】 (Third embodiment) Figure 18 is a plan view showing the workpiece arrangement pattern of the sheet S7 according to the third embodiment. The processing apparatus 100 according to this third embodiment has the same mechanical configuration as the processing apparatus 100 according to the first embodiment. Furthermore, the control unit 45 of the processing apparatus 100 according to this third embodiment is controlled according to the same control flow as the control unit 45 according to the first embodiment. 【0181】 Figure 18 shows how four crease-free workpieces Q9-Q12 are produced from a single sheet S7. The size and length-to-width ratio of each of the four workpieces Q9-Q12 may be the same or different. 【0182】 In the cutting device 3, first, the sheet S7, which is transported in the first direction A, is cut along the second direction B, which is perpendicular to the first direction A, at a position C3 that is three-quarters of the way from the leading edge Sf of the sheet S7 in the first direction A, which is the longitudinal direction of the sheet S7. 【0183】 Sheet S7 is divided into two sheets, sheet S8 and sheet S9. Sheets S8 and S9 are transported one by one to the processing device 7 by the cross conveyor device 4, with the transport direction F changed to the second direction B. Next, sheet S8, which is being transported in the second direction B, is cut along the second direction B using six cutting lines D17-D22 that are parallel to the second direction B. Then, it is sequentially cut along the first direction A, which is perpendicular to the second direction B, using cutting lines E5 and E6 to obtain processed products Q9-Q11. After that, the subsequent sheet S9 is transported from the cross conveyor device 4 towards the processing device 7 in the second direction B. Sheet S9 is cut along the second direction B using two cutting lines D23 and D24 that are parallel to the second direction B. Then, it is sequentially cut along the first direction A, which is perpendicular to the second direction B, using cutting lines E5 and E6. 【0184】 When processing the sheet S7 according to the third embodiment, similar to the first embodiment, the process is determined by moving each processing member 29 to a specific position in the width direction W and processing the sheet S, according to the control flow shown in Figure 5. 【0185】 At this point, in step 1 of Figure 5, a job is constructed for the placement of the processed members 29 in the transport path 5 based on the arrangement pattern of the workpieces Q9-Q12 on the sheet S7. In the processing shown in Figure 18, the sheet S8 that is transported first has six cutting lines D17-D22 set, and the subsequent sheet S9 has two cutting lines D23 and D24 set. Therefore, two types of jobs E and F are generated for sheet S8 and the subsequent sheet S9, with different cutting positions of the slitter 36. 【0186】 Job E has six cutting lines D17-D22 set along the transport direction. Figure 19 is a diagram illustrating Job E. In Job E, six cutting lines D17-D22 are set in the transport direction F of the sheet S7, which is the same as the arrangement of the slitter 36 for the sheet S6 in the second embodiment. 【0187】 Figure 20 illustrates the arrangement of the slitter 36 in job F. In job F, two cutting lines D23 and D24 are set in the conveying direction F of the sheet S8, which is the same as the arrangement of the slitter 36 in the sheet S2 of the first embodiment. 【0188】 In step 2 of Figure 5, the constructed jobs E and F are sorted in descending order by the number of processed parts 29 required. Job E uses 6 slitters 36, and Job F uses 2 slitters. In this case, when jobs E and F are sorted in descending order, job E is the first and job F is the second. 【0189】 In Step 3, Job E, which is determined to require the largest number of slitter 36s, will be designated as the baseline job. This baseline job E will be designated as Job 1. The other job, Job F, will be designated as Job 2. 【0190】 In step 4, it is determined whether the arrangement of the processed parts 29 can be rearranged. If it is determined in step 4 that the arrangement of the processed parts 29 can be rearranged, the process proceeds to step 5, where job 1 is used as the reference job, and the arrangement of the processed parts 2 in the other job 2 is controlled to match the arrangement in job 1. If the arrangement of the processed parts 29 cannot be rearranged, the process proceeds to step 6 and terminates without rearranging the arrangement of the processed parts 29. 【0191】 In this third embodiment, when executing the replacement control flow shown in Figures 10 and 11, in step 11 of Figure 10, the multiple slitters 361-366 whose positions in the width direction W have been determined in Job 1 and Job 2 are numbered in order of increasing length from the reference line G. 【0192】 In step 12, set job number N to 2. The arrangement of the slitter 36 in job E, which is designated as the reference job 1, is a processing operation along the conveying direction F of the sheet S8 shown in Figure 19. In accordance with the arrangement of the slitter 36 in job 1 shown in Figure 19, we sequentially determine how to switch the arrangement of the slitter 36 in job F, which is designated as job 2, shown in Figure 20. In step 13, set i=0. 【0193】 In step 14, determine whether the identification number of the first slitter 361 in job 2 is the same as the identification number of the first slitter 361 in job 1 that has the shortest distance from the baseline G. 【0194】 The identification number of the first slitter 361 in Job 2 is 1, which is the same as the identification number 1 of the first slitter 361 in Job 1. In this case, since both Job 1 and Job 2 use the same slitter 361 with identification number 1, there is no need to swap them. At this point, step 14 is satisfied and the process proceeds to step 17. 【0195】 In step 17, increment i. Proceed to step 18 and determine if the value of i is less than the number of slitter 36 used in job 2. Since job 2 uses 2 slitter 36, i=1, which is less than the 2 slitters used in job 2. In this case, step 18 is satisfied, and return to step 14. 【0196】 In step 14, determine whether the identification number of the second slitter 36 in job 2, shown in Figure 20, is the same as the identification number of the second slitter in job 1, shown in Figure 19. In job 1, the identification number of the second slitter 36 is 3, and in job 2, it is 2. In this case, the two are different, so step 14 is not satisfied, and proceed to step 15. In step 15, determine whether slitter 362 with identification number 2 in job 2 can be swapped with slitter 363 with identification number 3 in job 1. 【0197】 As shown in Figure 20, in both slitter 362 (identification number 2) and slitter 363 (identification number 3), the lower cutting blade 36b is positioned on the left side and the upper cutting blade 36a is positioned on the right side of the pressure contact portion 343 of the upper and lower cutting blades 36a and 36b. In this case, slitter 362 and slitter 363 can be interchanged. Since step 15 is satisfied, proceed to step 16. 【0198】 In step 16, the second slitter 362 of job 2 is set to be changed from slitter 363 with identification number 3 to slitter 362 with identification number 2. As a result, when the cutting line D24 of sheet 8 is creasing, the setting is changed to use slitter 363 on the left side of the second unit 20b instead of slitter 362 on the right side of the first unit 20a. Consequently, when sheets S8 and S9 are alternately transported to the slitter section 20 and processed, sheet S9 can be processed using slitter 36 on the left side of the second unit 20b, which has the shortest travel distance, instead of using slitter 36 on the right side of the first unit 20a in the width direction W. Therefore, the time required to move the processing material 29 can be shortened, and the processing time for sheet S7 can be shortened. 【0199】 Proceed to step 17 in Figure 10 and increment i. In step 18, determine if the value of i is less than the number of slitters 36 used in job 2. At this point, the value of i is 2, and the number of slitters used in job 2 is 2. Therefore, step 18 is not satisfied, and proceed to step 19 in Figure 11. 【0200】 In step 19, we determine if the value of i is greater than or equal to the number of slitter 36 used in job 1. At this point, the value of i is 2, and the number of slitter 36 used in job 1 is 6. Therefore, step 19 is not met, and we proceed to step 20. 【0201】 In step 20, the length Sw in the width direction W of sheet S9 is compared with whether it is greater than or equal to the length from the reference line of job 1 to the processing position of the third slitter 36 plus a predetermined amount α. If the length Sw to the third slitter 363 of job 1 is not greater than or equal to the length Sw in the width direction W of sheet S9 plus a predetermined amount α, the third slitter 363 of job 2 is set to move to an avoidance position, which is moved by a predetermined amount α away from the width direction W of sheet S8. 【0202】 Proceed to step 21 and increment i. In step 22, determine if the value of i is less than the number of 36 slitters used in job 1. At this point, the value of i is 3, and the number of slitters used in job 1 is 6, so step 22 is satisfied and proceed to step 23. 【0203】 In step 23, the slitter 366, which is the fourth slitter 36 in job 1 and forms the cutting line D20 of sheet S8, is set to wait at a position in the width direction W for forming the cutting line D20 of sheet S8 when sheet S9 is being processed. As a result, the slitter 366 on the right side of the third unit 20c waits in the waiting position without performing any processing when sheet S9 is being processed. Then, when the subsequent sheet S8 is transported, it forms the cutting line 20 of sheet S8 while remaining at this position in the width direction W. As a result, both sheet S8 and sheet S9 can be processed without moving the slitter 366. The time required to move the slitter 366 in the width direction W is eliminated, and the processing time can be shortened. 【0204】 Return to step 21 from step 23. In step 21, increment i. In step 22, determine if the value of i is less than the number of slitter 36 used in job 1. At this point, the value of i is 4, and the number of slitter 36 used in job 1 is 6, so step 22 is satisfied. In this case, proceed to step 23. 【0205】 In step 23, similar to slitter 366, slitter 364, which is the fifth slitter 36 in job 1 and will form the cutting line D21 of sheet S8, is set to wait at a position in the width direction W for forming the cutting line D21 of sheet S8 when processing sheet S9. 【0206】 From this point onward, the slitter 364 on the right side of the second unit 20b remains in a standby position without performing any processing during the processing of sheet S9. Then, when the subsequent sheet S8 is transported, it forms the cutting line 21 of sheet S8 while remaining in this position in the width direction W. Thus, both sheet S8 and sheet S9 can be processed without moving the slitter 364. Since there is no time required to move the slitter 364 in the width direction W, the processing time can be shortened. 【0207】 From step 23, return to step 21. In step 21, increment i. In step 22, determine if the value of i is less than the number of slitter 36 used in job 1. At this point, the value of i is 5, and the number of slitter 36 used in job 1 is 6, so step 22 is satisfied, and proceed to step 23. 【0208】 In step 23, similar to slitters 364 and 366, slitter 362, which is the sixth slitter in job 1 and forms the cutting line D22 of sheet S8, is set to wait at a position in the width direction W for forming the cutting line D22 of sheet S8 when processing sheet S9. 【0209】 From this point onward, the slitter 362 on the right side of the first unit 20a remains in a standby position without performing any processing during the processing of sheet S9. Then, when the subsequent sheet S8 is transported, the cutting line 22 of sheet S8 is formed while the slitter 362 remains in this position in the width direction W. Thus, both sheet S8 and sheet S9 can be processed without moving the slitter 362. This eliminates the time required to move the slitter 362 in the width direction W, thus shortening the processing time. 【0210】 From step 23, return to step 21. In step 21, increment i. In step 22, determine if the value of i is less than the number of slitter 36 used in job 1. At this point, the value of i is 6, and the number of slitter 36 used in job 1 is 6, so step 22 is not satisfied. In this case, proceed to step 24. 【0211】 In step 24, N is incremented. Proceed to step 25 and determine whether the value of N is less than the number of active jobs. Sheet S4 shown in Figure 18 has two jobs running, Job E and Job F, so the number of active jobs is 2. On the other hand, the value of N is 3, so step 25 is not met and the process ends. 【0212】 In the above embodiment, the sheet arrangement pattern is not limited to those illustrated in each figure, and various other patterns can be set regarding the number and position of cutting lines and fold lines.
