Mode for Carrying Out the Invention

[0008] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a diagram showing the overall configuration of the image forming system 100. The image forming system 100 of the present embodiment is provided with an image forming apparatus 1 that forms an image on a sheet S, which is an example of a recording medium, a sheet feeding apparatus 2 that supplies a printed sheet T or a colored sheet T, and a sheet processing apparatus 3 that performs processing on the sheet S on which an image is formed by the image forming apparatus 1 and the sheet T supplied by the sheet feeding apparatus 2.

[0009] The image forming apparatus 1 is provided with an image forming unit 10 that forms an image on the sheet S based on image data. The image forming unit 10 forms an image on the sheet S using an existing image forming method such as an inkjet method or an electrophotographic method. In addition, the image forming apparatus 1 is provided with an image reading unit 11 that reads an image formed on a document and generates image data, and a sheet feeding unit 12 that supplies the sheet S to the image forming unit 10.

[0010] In addition, the image forming apparatus 1 is provided with a user interface 13 that receives an operation input from a user and presents information to the user. This user interface 13 is configured by, for example, a touch panel. In addition, the image forming apparatus 1 is provided with a main control unit 14 that includes a CPU (Central Processing Unit), a ROM (Read Only Memory), etc. and controls the operation of the entire image forming system 100.

[0011] In this case, the image forming system 100 may be provided with other paper processing devices (not shown) following the paper processing device 3. In other words, the image forming system 100 may be equipped with other paper processing devices that process the paper S that has passed through the paper processing device 3. Other paper processing devices perform processes such as folding, punching, and binding on the paper S that has passed through the paper processing device 3. In this specification, other paper processing devices will be referred to as "successor processing devices."

[0012] Figure 2 is an enlarged view of the paper processing device 3. As an example of a recording medium processing apparatus, the paper processing apparatus 3 is equipped with a crease forming unit 307 for forming creases on the paper S, and a side edge removal unit 308 for removing the side edges of the paper S. Furthermore, as shown in Figure 1, the paper processing device 3 is configured to include a CPU (Central Processing Unit), ROM (Read Only Memory), and other components, and is equipped with a processing control unit 31 that controls each functional part of the paper processing device 3. Furthermore, as shown in Figure 1, the paper processing device 3 is equipped with a user interface (UI) 32 that accepts user input regarding the processing of paper S. This user interface 32 is configured, for example, as a touch panel.

[0013] In this embodiment, the processing control unit 31 is located within the paper processing apparatus 3, but the processing control unit 31 may also be located within the image forming apparatus 1. Furthermore, the main control unit 14 may also be configured to incorporate the control functions of the processing control unit 31. Furthermore, although the user interface 32 is provided on the paper processing apparatus 3 in this embodiment, the user interface 32 may also be provided on the image forming apparatus 1. Alternatively, the user interface 13 may be configured to also perform the functions of the user interface 32.

[0014] <Description of Paper Processing Device 3> As shown in Figure 2, the paper processing apparatus 3 is provided with a receiving port 301 for receiving paper S transported from the image forming apparatus 1, and a discharge port 302 for discharging the paper S. Furthermore, the paper processing device 3 is equipped with a tilt detection unit 303 for detecting the tilt of the paper S, and a first tilt correction unit 304 which has a swing roll 42 for correcting the tilt of the paper S. Furthermore, the paper processing device 3 is equipped with a second tilt correction unit 305 that corrects the tilt of the paper S, which has a tilt correction roll 43 that the leading edge of the paper S abuts against.

[0015] Furthermore, the paper processing device 3 is provided with a crease forming unit 307 for forming creases in the paper S, as described above. Also, the paper processing device 3 is provided with a side edge removal unit 308 for removing the side edges of the paper S, as described above. Furthermore, the paper processing device 3 is provided with a storage section 309 for accommodating the removed side edges.

[0016] Furthermore, the paper processing device 3 is provided with a first paper transport path R1 through which the paper S passes. The first paper transport path R1 is provided so as to start from the receiving port 301 and proceed toward the discharge port 302. The first paper transport path R1 passes through the tilt detection unit 303, the first tilt correction unit 304, the second tilt correction unit 305, the crease formation unit 307, and the side edge removal unit 308.

[0017] The first paper transport path R1 branches off at a branching section β located downstream of the side edge removal section 308. As a result, in this embodiment, a first branch path R11 and a second branch path R12 are provided in a part of the first paper transport path R1. The first branch route R11 and the second branch route R12 merge at the confluence γ located just before the outlet 302.

[0018] Furthermore, the paper processing device 3 is provided with a second paper transport path R2. The second paper transport path R2 is provided to branch off from the first paper transport path R1. The second paper transport path R2 branches off from the first paper transport path R1 at a branching point α located downstream of the first tilt correction unit 304 and upstream of the crease forming unit 307. The second paper transport path R2 starts at branching point α and proceeds towards the discharge port 302.

[0019] In this embodiment, paper S that does not undergo creasing by the creasing forming unit 307, and paper S that does not undergo edge removal by the edge removal unit 308, proceed towards the discharge port 302 via the second paper transport path R2. Although not shown in the diagram, in this embodiment, each of the branching section α and branching section β is provided with a switching member for switching the transport path to which the paper S is headed.

[0020] The first paper transport path R1 and the second paper transport path R2 are equipped with multiple transport rolls 41 that transport the paper S located on these paper transport paths downstream. The conveyor roll 41 consists of a drive roll 41A that is rotationally driven by a motor, and a driven roll 41B that rotates by receiving driving force from the drive roll 41A. The drive roll 41A and the driven roll 41B have a structure in which multiple cylindrical elastic bodies made of rubber or the like are attached to a shaft made of metal or the like.

[0021] In the conveying roll 41, the elastic body provided on the drive roll 41A and the elastic body provided on the driven roll 41B are in contact. In this state, in this embodiment, the drive roll 41A rotates. Consequently, the driven roll 41B rotates. When a sheet of paper S is caught between the drive roll 41A and the driven roll 41B, the sheet of paper S moves downstream due to the force from the drive roll 41A and the driven roll 41B.

[0022] The tilt detection unit 303 is provided with two sets of detection members, each consisting of a pair of light-emitting elements and a light-receiving elements. These two sets of detection members are positioned differently from each other in a direction perpendicular to the paper transport direction of the paper S. If the paper S is not passing through, the light-receiving element receives light emitted from the light-emitting element. The tilt detection unit 303 detects the tilt of the paper S based on the timing at which each of the two sets of detection members detects the leading edge of the paper S.

[0023] If the paper S is detected to be tilted, the swing roll 42 moves according to the amount of tilt of the paper S detected by the tilt detection unit 303. Specifically, in this embodiment, if it is detected that the paper S is tilted, the swing roll 42 is first tilted according to this tilt. Then, when the drive roll 42A and the driven roll 42B, which are provided on the swing roll 42, grip the paper S, the drive roll 42A and the driven roll 42B are displaced from a tilted state to an upright state. This corrects the tilt of the paper S.

[0024] Here, the swing roll 42, like the conveyor roll 41, is composed of a drive roll 42A that is rotationally driven by a motor and a driven roll 42B that rotates by receiving driving force from the drive roll 42A. In this embodiment, one end of the drive roll 42A and the driven roll 42B in the axial direction is fixed. The other end of the drive roll 42A and the driven roll 42B in the axial direction moves upstream and downstream in the conveying direction of the paper S. As this other end moves upstream and downstream in the direction of paper transport, the tilt of the swing roll 42 changes, thereby correcting the tilt of the paper S as described above.

[0025] The second tilt correction unit 305 further reduces the tilt of the paper S. The second tilt correction unit 305 includes a correction roll 43 against which the leading edge of the transported paper S abuts. The compensating roll 43, like the transport roll 41, is composed of a drive roll 43A that is rotationally driven by a motor and a driven roll 43B that rotates by receiving the driving force from the drive roll 43A.

[0026] The correction roll 43 is set to a state where its rotation stops when the paper S hits the correction roll 43. In this state, as the paper S hits the correction roll 43 and is further fed, the paper S bends. Subsequently, the correction roll 43 begins to rotate. This causes the paper S, now with its tilt corrected, to be transported downstream. Upstream of the correction roll 43, a deflection accommodating section 44 is provided to accommodate the bent portion of the paper S.

[0027] The creasing section 307 has an advancing member that extends from the side of the first paper transport path R1 toward the first paper transport path R1. In the creasing section 307, this advancing member is pressed against the paper S, thereby forming creasing lines on the paper S. In this embodiment, when folding is performed in a subsequent processing device, the extension member extends to the portion of the paper S that is to be folded. This forms a fold line in the paper S. Once a fold line is formed in the paper S, the folding process in the subsequent processing device can be performed more smoothly.

[0028] The formation of creases by the crease-forming unit 307 is not mandatory. For example, if folding is not performed in a subsequent processing device, the formation of creases by the crease-forming unit 307 may be omitted. Furthermore, the system may decide whether or not to form creases using the crease-forming unit 307 based on instructions from the user, and if the user instructs not to form creases, the system may prevent the formation of creases. If the crease formation unit 307 does not form a crease, the paper S moves towards the side edge removal unit 308 without any creases formed.

[0029] The edge removal unit 308 is a trimming device that removes the edge of the rectangularly shaped paper S. More specifically, the edge removal unit 308 removes the edge of the rectangularly shaped paper S that is along the first paper transport path R1. The side edge removal section 308 is provided with a cutting mechanism 400 for cutting the paper S. This cutting mechanism 400 is provided with a disc-shaped rotating blade 410 fixed to an axis extending in a direction perpendicular to the paper S transport direction.

[0030] There are two rotating blades 410. Figure 2 shows one of the two rotating blades 410. The two rotating blades 410 are positioned so that their positions are different from each other in a direction perpendicular to the paper transport direction S. In this embodiment, the rotating blade 410 cuts the paper S, and of the four side edges of the rectangularly shaped paper S, two side edges along the first paper transport path R1 are removed. Furthermore, it is not limited to removing both lateral edges; it is also possible to remove only one of the two lateral edges.

[0031] Each of the rotating blades 410 can move in a direction perpendicular to the paper transport direction of the paper S. In other words, each of the rotating blades 410 can move in a direction perpendicular to the paper plane in Figure 2. As a result, in this embodiment, the side edges of the paper S can be removed even if the size of the paper S changes. Furthermore, in this embodiment, the rotating blade 410 is movable in a direction perpendicular to the transport direction of the paper S, thereby allowing adjustment of the width of the side edges to be removed. In this embodiment, the removed side edge travels through the side edge path RS to the housing section 309 and is housed in this housing section 309.

[0032] The removal of the side edges by the side edge removal section 308 is not mandatory; for example, if instructed by the user, the removal of the side edges may be omitted. In other words, the decision of whether or not to remove the side edge using the side edge removal unit 308 may be made based on instructions from the user, and if the user instructs not to remove the side edge, the side edge removal may not be performed. If the side edges are not removed by the side edge removal unit 308, the paper S will proceed to the discharge port 302 with its side edges intact.

[0033] The processing flow in the paper processing device 3 will be explained. First, we will explain the processing flow when paper S is transported along the first paper transport path R1. In this embodiment, first, the paper S on which an image has been formed in the image forming apparatus 1 is transported to the paper processing apparatus 3 (see Figure 2) via the paper supply device 2. In the paper processing device 3, first, the tilt detection unit 303 detects the tilt of the paper S. Then, the first tilt correction unit 304 and the second tilt correction unit 305 correct the tilt of the paper S.

[0034] Next, the crease forming unit 307 forms creases in the paper S. Then, the side edges of the paper S are removed by the side edge removal unit 308. Subsequently, the paper S is sent to the first branching path R11. Then, on this first branching path R11, the paper S (hereinafter referred to as "preceding paper S") temporarily stops. Subsequently, the paper S that was transported following the preceding paper S (hereinafter referred to as "subsequent paper S") is sent to the second branching path R12. The same processing as the preceding paper S is performed on this subsequent paper S. Specifically, the subsequent paper S undergoes crease formation and removal of side edges.

[0035] In this embodiment, when the subsequent paper S is transported to the second branch path R12, the transport of the preceding paper S, which is stopped in the first branch path R11, is resumed. As a result, in this embodiment, both the preceding paper S and the subsequent paper S move towards the discharge port 302. The first branch path R11 functions as a buffer for holding the paper S, and in this embodiment, when time-consuming processing such as folding the stack of paper is performed in a subsequent processing unit, the preceding paper S is sent to the first branch path R11 as described above. Then, at the moment when the subsequent paper S is transported to the second branching path R12, the transport of the preceding paper S, which is stopped in the first branching path R11, is resumed, and both the preceding paper S and the subsequent paper S are transported to the subsequent processing unit.

[0036] Here, we assume that there are no two branching paths, the first branching path R11 and the second branching path R12. In this case, the subsequent paper S cannot be processed by the paper processing device 3, and it becomes necessary to wait for the processing in the subsequent processing device to finish before starting processing in the paper processing device 3.

[0037] Furthermore, if the first branching path R11 and the second branching path R12 are not provided, it may be necessary to wait for the subsequent paper S to finish processing in the subsequent processing device before starting image formation in the image forming apparatus 1. In contrast, as in this embodiment, if two branching paths are provided, a first branching path R11 and a second branching path R12, processing of the subsequent paper S can proceed without waiting for the processing in the subsequent processing device to finish.

[0038] Note that while this explanation describes the case where both the first branch route R11 and the second branch route R12 are used, it is not mandatory to use both of these branch routes. If there is a user instruction, or if no processing is performed by a subsequent processing unit, or if other predetermined conditions are met, the paper S may be allowed to pass through only one of the branch paths, either the first branch path R11 or the second branch path R12. Alternatively, instead of providing two branching paths, the first branching path R11 and the second branching path R12, the system may be configured to provide only one path.

[0039] Next, we will explain the case where the paper S is transported through the second paper transport path R2. If predetermined conditions are met, such as when processing is not performed in the paper processing device 3, the paper S moves through the second paper transport path R2, which branches off from the first paper transport path R1. More specifically, if, for example, processing by the fold-forming unit 307 or processing by the side-edge removal unit 308 is not performed, the paper S moves through the second paper transport path R2.

[0040] When the paper S moves along the second paper transport path R2, the tilt detection unit 303 detects the tilt of the paper S. Then, the first tilt correction unit 304 corrects the tilt of the paper S. As a result, in this case, the paper S, whose tilt has been corrected, travels through the second paper transport path R2 towards the output port 302.

[0041] Next, the configuration of the side edge removal section 308 will be described. In this embodiment, as shown in Figure 2, a cutting mechanism 400, which is an example of a cutting means, is provided in the side edge removal section 308. In this embodiment, as described above, the paper S is cut by this cutting mechanism 400, and the side edges of the paper S are removed.

[0042] Figure 3 shows the cutting mechanism 400 as viewed from the direction indicated by arrow III in Figure 2 and from the rear side of the paper processing device 3. Figure 4 is an enlarged view of the part indicated by reference numeral 4X in Figure 3 as viewed from the direction indicated by arrow IV. As shown in Figures 3 and 4, the cutting mechanism 400 is equipped with a disc-shaped rotating blade 410. Also, as shown in Figures 3 and 4, the cutting mechanism 400 is equipped with a disc-shaped opposing blade 420 that rotates.

[0043] Furthermore, the cutting mechanism 400 is equipped with a transport roll 430 (hereinafter referred to as "cutting transport roll 430") for transporting the paper S, as shown in Figure 3. Here, the cutting conveyor roll 430 is composed of multiple conveyor rolls. In this embodiment, the multiple transport rolls provided are a left-side transport roll 431, a right-side transport roll 432, and a central transport roll 433. In this embodiment, in the paper transport direction of the paper S, the central transport roll 433 is positioned downstream of the left transport roll 431 and the right transport roll 432.

[0044] Each of the left-side conveyor roll 431, the right-side conveyor roll 432, and the central conveyor roll 433 consists of a drive roll 430A that is rotationally driven by a motor, and a driven roll 430B that rotates by receiving driving force from the drive roll 430A. The driven roll 430A and the driven roll 430B have a structure similar to that described above, in which multiple cylindrical elastic bodies made of rubber or the like are attached to a shaft made of, for example, metal.

[0045] In this embodiment, as shown in Figure 3, two sets of rotating blades 410 and opposing blades 420 are provided. Specifically, in this embodiment, a first set of rotary blades 410 and opposing blades 420 located on the left side in the figure are provided for removing one side edge of the paper S, and a second set of rotary blades 410 and opposing blades 420 located on the right side in the figure are provided for removing the other side edge of the paper S.

[0046] In this embodiment, the first pair of rotating blades 410 are arranged coaxially with the drive roll 430A provided on the left-side conveyor roll 431, and the first pair of opposing blades 420 are arranged coaxially with the driven roll 430B provided on the left-side conveyor roll 431. The first pair of rotating blades 410 is supported by a shaft 440 of a drive roll 430A provided on the left-side conveyor roll 431, and the first pair of opposing blades 420 is supported by a shaft 440 of a driven roll 430B provided on the left-side conveyor roll 431.

[0047] Furthermore, in this embodiment, the second set of rotating blades 410 is arranged coaxially with the drive roll 430A provided on the right-side conveyor roll 432, and the second set of opposing blades 420 is arranged coaxially with the driven roll 430B provided on the right-side conveyor roll 432. The second set of rotating blades 410 is supported by a shaft 440 of a drive roll 430A provided on the right-side conveyor roll 432, and the second set of opposing blades 420 is supported by a shaft 440 of a driven roll 430B provided on the right-side conveyor roll 432.

[0048] As shown in Figure 4, a portion of the opposing blade 420 is positioned opposite one of the faces 410A of the rotating blade 410. More specifically, in this embodiment, the outer periphery 420A of the opposing blade 420 is positioned opposite one of the faces 410A of the rotating blade 410. Although Figure 4 shows the rotating blade 410 and opposing blade 420 provided on the left-side conveyor roll 431, the rotating blade 410 and opposing blade 420 provided on the right-side conveyor roll 432 (see Figure 3) have the same configuration as the rotating blade 410 and opposing blade 420 provided on the left-side conveyor roll 431.

[0049] As shown in Figure 4, the opposing blade 420 is positioned at a different location from the rotating blade 410 in the axial direction of the rotating blade 410. Furthermore, the opposing blade 420 is positioned at a different location from the rotating blade 410 in the radial direction of the rotating blade 410. In this embodiment, the rotating blade 410 and the opposing blade 420 are not arranged coaxially, and the rotation axis 420C of the opposing blade 420 is located off-center from the rotation axis 410C of the rotating blade 410.

[0050] Furthermore, in this embodiment, as shown in Figure 4, a disc-shaped muscle-forming member 450 is provided. This rib-forming member 450 is supported by a shaft 440 of a driven roll 430B provided on the left-side conveyor roll 431 (see Figure 3). This rib-forming member 450 is arranged coaxially with the opposing blade 420.

[0051] In this embodiment, as shown in Figure 4, the outer diameter of the muscle-forming member 450 is larger than the outer diameter of the opposing blade 420. The groove-forming member 450 forms grooves along the direction of the cut pieces that are generated in one direction by the cutting of the paper S by the cutting mechanism 400. In this embodiment, the removal of the side edges of the paper S results in a cut piece formed by these side edges. In this embodiment, the groove-forming member 450 is pressed against this cut piece to form grooves on the cut piece along the direction of movement of the cut piece.

[0052] More specifically, in this embodiment, the portion of the paper S indicated by reference numeral 4A in Figure 4 becomes the cut piece. The portion indicated by reference numeral 4B in Figure 4 becomes the main body of the paper that remains uncut. The cut piece moves in a direction perpendicular to the plane of Figure 4 and toward the front of the plane of Figure 4. In this embodiment, the groove-forming member 450 is pressed against the cut piece, thereby forming grooves on the cut piece along the direction of movement of the cut piece.

[0053] Referring to Figure 3, in this embodiment, cutting the paper S produces a cut piece pointing in one direction, as indicated by arrow 3A in the figure. In this embodiment, the groove-forming member 450 forms grooves along this one direction on the cut piece point pointing in one direction. As in this embodiment, when grooves are formed on the cut piece along the direction of movement of the cut piece, the straight-line stability of the cut piece is increased, and it becomes less likely that the cut piece will move to a location other than the housing section 309 (see Figure 2).

[0054] Furthermore, in this embodiment, as shown in Figure 4, a biasing member 460 is provided that biases the paper S against the outer circumferential surface of the opposing blade 420. The biasing member 460 is made of a material that is harder than rubber, such as POM (polyacetal). The biasing member 460 is supported by a shaft 440 of the drive roll 430A, which is provided on the left-side conveying roll 431 (see Figure 3). The biasing member 460 is formed in a disc shape, and its outer circumference 460A contacts the outer circumference 420K of the opposing blade 420. In this embodiment, in the axial direction of the rotating blade 410, the muscle-forming member 450 is provided on the side opposite to the side on which the rotating blade 410 is provided, with the biasing member 460 in between.

[0055] In this configuration, if the biasing member 460 is not provided and the paper S is not pressed against the outer peripheral surface 420K of the opposing blade 420, the paper body is more likely to enter the region R100 on the opposing blade 420 side, as indicated by reference numeral 5A in Figure 5 (a diagram showing the state of the paper when the biasing member 460 is not provided). In this case, the paper S becomes more easily torn, and the quality of the paper S after cutting tends to deteriorate.

[0056] In contrast, as in this embodiment, when the paper S is pressed against the outer peripheral surface 420K of the opposing blade 420 by the biasing member 460 (see Figure 4), the paper body is more likely to follow the straight line LS that passes through the boundary between the region R100 (see Figure 5) on the opposing blade 420 side and the region R200 (see Figure 5) on the rotating blade 410 side. Alternatively, the paper body is more likely to be located in the region R200 on the rotating blade 410 side than in this straight line LS. In this case, the situation where paper S is torn becomes less likely.

[0057] Figures 6(A) and (B) are enlarged views of the side edge removal section 308. In this embodiment, as shown in Figure 6(A), the edge removal portion 308 is provided with a pressing portion 510 against which one side of the paper S (not shown in Figure 6(A)) is pressed. The pressing portion 510 is located upstream of the cutting mechanism 400 in the paper transport direction of the paper S. Furthermore, as shown in Figure 6(A), the side edge removal section 308 of this embodiment is provided with a transport roll 520 (hereinafter referred to as the "upstream transport roll 520") which is positioned upstream of the pressing section 510 and transports the paper S downstream.

[0058] The upstream conveying roll 520 is composed of a drive roll 520A that is rotationally driven by a motor, and a driven roll 520B that rotates by receiving driving force from the drive roll 520A, as described above. Furthermore, in this embodiment, a pressing mechanism 540 is provided as an example of a pressing means for pressing one side S1 of the conveyed paper S (see Figure 6(B)) against the pressing portion 510.

[0059] The side edge removal section 308 (see Figure 6(A)) is provided with multiple transport means for transporting the paper S. Specifically, in this embodiment, the multiple transport means include a cutting transport roll 430 provided on the cutting mechanism 400 and an upstream transport roll 520 positioned upstream of the pressing portion 510. These multiple transport means are arranged so that their positions in the transport direction of the paper S are offset from each other.

[0060] In this embodiment, the transport speed of the paper S by the cutting transport roll 430, which is an example of another transport means located downstream of the first transport means, is greater than the transport speed of the paper S by the upstream transport roll 520, which is an example of one transport means. As a result, in this embodiment, the slack paper S is pulled taut, and as shown in Figure 6(B), one side S1 of the paper S is pressed against the opposing pressing portion 510 located on the opposite side of S1.

[0061] In this embodiment, the paper S fed out by the upstream transport roll 520 (see Figure 6(B)) does not go straight towards the cutting transport roll 430. In this embodiment, the paper S is fed downwards from the straight line L connecting the upstream transport roll 520 and the cutting transport roll 430.

[0062] In other words, the paper S fed out by the upstream transport roll 520 (see Figure 6(B)) does not go straight to the cutting transport roll 430, but rather goes downwards from the imaginary plane H that passes through the upstream transport roll 520 and the cutting transport roll 430. Note that the "cutting conveyor roll 430" here refers to the left conveyor roll 431 (see Figure 3) and the right conveyor roll 432, which are located one downstream from the upstream conveyor roll 520, and does not include the central conveyor roll 433 (see Figure 3).

[0063] The straight line L is a straight line connecting the point K1 where the driven roll 520A and the driven roll 520B on the upstream conveyor roll 520 come into contact, and the point K2 where the driven roll 430A and the driven roll 430B on the left conveyor roll 431 and the right conveyor roll 432, respectively, come into contact. Plane H is a plane that passes through a point K1 where the drive roll 520A and the driven roll 520B on the upstream transport roll 520 come into contact, and a point K2 where the drive roll 430A and the driven roll 430B on the left transport roll 431 and the right transport roll 432 come into contact, and extends in a direction perpendicular to the transport direction of the paper S. In this embodiment, the paper S fed out by the upstream transport roll 520 is configured to be fed out below the straight line L and the plane H.

[0064] The paper S, which is fed downwards from the straight line L and the plane H, is guided by a guide member (not shown) located below the pressing section 510, and moves toward the cutting transport roll 430. More specifically, this paper S is guided by a guide member located below the pressing section 510, and moves toward the cutting transport roll 430. In this embodiment, when the paper S reaches the cutting transport roll 430, the paper S is in a slack state.

[0065] In this embodiment, from this state, the cutting transport roll 430 pulls the paper S, which gradually reduces the slack in the paper S, and eventually, as shown in Figure 6(B), one side S1 of the paper S is pressed against the pressing portion 510. In this embodiment, the pressing mechanism 540 is composed of an upstream transport roll 520 and a cutting transport roll 430, and one side S1 of the paper S is pressed against the pressing portion 510 by the upstream transport roll 520 and the cutting transport roll 430.

[0066] Furthermore, the upstream transport roll 520 may be set to a state where its rotation is stopped when the paper S is transported to it. In this case, the paper S will bend as it comes into contact with the stopped upstream transport roll 520 and is further fed into the machine. In this case, the rotation of the upstream transport roll 520 begins after the paper S has flexed. As a result, the paper S, with its tilt corrected, is fed towards the cutting mechanism 400.

[0067] In this embodiment, the paper S is positioned on the side of one of the two opposing regions R3 and R4, which are separated by a straight line L (see Figure 6(B)) connecting the upstream transport roll 520 and the cutting transport roll 430, specifically on the side of region R3. Furthermore, in this embodiment, at least a portion of the pressed portion 510 is positioned on the side of one of the regions R3. In this embodiment, a portion of the pressed portion 510 is positioned on one side of region R3, but it is also possible to configure the entire pressed portion 510 to be positioned on one side of region R3.

[0068] The part that is pressed against the paper 510 extends in a direction intersecting the transport direction of the transported paper S. More specifically, the part that is pressed against the paper 510 extends in a direction perpendicular to the transport direction of the transported paper S. In other words, the part that is pressed against the paper 510 extends in a direction perpendicular to the plane of the paper in Figure 6. Furthermore, the pressing portion 510 is formed in a cylindrical or columnar shape and is rotatable around a rotation axis 20C (see Figure 6(B)) that extends in a direction intersecting the transport direction of the paper S. In this embodiment, the pressing mechanism 540 presses one side S1 of the paper S against the pressed portion 510, which extends in a direction intersecting the transport direction of the paper S.

[0069] In this embodiment, the pressed portion 510 receives the force from the paper S that is pressed against it. As a result, the pressed portion 510 rotates in accordance with the paper S. It is not essential that the part being pressed against 510 rotates; the part being pressed against 510 may be provided in a non-rotating state. Furthermore, the shape of the part to be pressed against 510 is not particularly limited and may be a shape other than cylindrical or columnar. For example, the part to be pressed against 510 may be a rectangular prism.

[0070] The pressing mechanism 540 pulls one end of the loose paper S away from the other end, thereby pressing the one side S1 of the paper S against the pressing portion 510 located at the opposite end of that side S1. More specifically, the pressing mechanism 540 presses one side S1 of the paper S against the part to be pressed 510 by pulling the leading edge ST1 side of the paper S away from the rear edge ST2 in the transport direction of the paper S. In this embodiment, the pressed portion 510 is arranged to extend along a direction intersecting the pulling direction of the paper S. More specifically, the pressed portion 510 is arranged to extend along a direction perpendicular to the pulling direction of the paper S.

[0071] In this embodiment, the cutting mechanism 400 cuts the paper S that is being pressed against the pressing portion 510. In this embodiment, when the paper S is pressed against the pressing portion 510, the distortion of the paper S is reduced, and as a result, cutting is performed on the paper S in a less distorted state. In this embodiment, the cutting mechanism 400 cuts the paper S along the pulling direction of the paper S. In this embodiment, as described above, the leading end ST1 side of the paper S is pulled away from the rear end ST2 in the transport direction, and the paper S is cut along this pulling direction. In this embodiment, a rotating blade 410 (see Figure 3) is provided along this pulling direction, and the paper S is cut along this pulling direction.

[0072] Figure 7 shows the side edge removal section 308 without the pressing portion 510. Figure 7 shows the state of the side edge removal section 308 as viewed from the downstream side in the paper transport direction of the paper S. As shown in Figure 7, distortion may occur in the side edge removal section 308 of the paper S. If the paper S is cut in this state, the cutting will occur in a location different from the originally intended location. In contrast, in this embodiment, where the paper S is pressed against a pressing portion 510 that extends along a direction intersecting the transport direction of the paper S, the distortion of the paper S is reduced, and the likelihood of cutting occurring at the intended location increases.

[0073] In this embodiment, the case in which the paper S is cut along the transport direction of the paper S has been described, but the direction in which the cutting is performed is not particularly limited, and for example, the paper S may be cut along a direction intersecting the transport direction of the paper S. In other words, although this embodiment describes the case in which the paper S is cut along the pulling direction of the paper S, the paper S may also be cut along a direction intersecting the pulling direction of the paper S. When cutting the paper S in a direction intersecting the paper transport direction, for example, the cutting blade extending in this intersecting direction is advanced into the paper S, or the rotary blade 410 is moved in this intersecting direction. This allows the paper S to be cut along this intersecting direction.

[0074] Figures 8(A) and 8(B) show other configuration examples of the side edge removal section 308. In this configuration example, as shown in Figure 8(A), the contact portion 510 is positioned to the side of the paper transport path and is composed of an inclined surface 90 that is inclined with respect to the direction of movement of the transported paper S. In this configuration example, the upstream transport roll 520, which functions as a pressing means, transports the paper S toward the inclined surface 90 and presses the surface of the paper S against the inclined surface 90, which is the part to be pressed 510, as shown in Figure 8(B). As a result, the distortion of the paper S is reduced, as described above.

[0075] In this configuration example shown in Figure 8, an inclined surface 90 is provided above the straight line L5 (see Figure 8(A)) connecting the upstream conveying roll 520 and the cutting conveying roll 430. Furthermore, in this configuration example, multiple inclined surfaces 90 are provided. These multiple inclined surfaces 90 are arranged so that their positions in the paper transport direction are different from each other. Furthermore, each of the inclined surfaces 90 is provided in a direction that intersects with the paper transport direction S. In other words, each of the inclined surfaces 90 is provided in a direction that is perpendicular to the paper plane in Figure 8.

[0076] In this embodiment, when the cutting mechanism 400 cuts the paper S, the paper S is pressed against multiple inclined surfaces 90, as shown in Figure 8(B). In this embodiment, one of the multiple inclined surfaces 90, the upstream inclined surface 90A, is positioned on the other side S2 of the paper being transported. Furthermore, the downstream inclined surface 90B, which is another inclined surface 90 located on the downstream side, is positioned on one side S1 of the paper S. In this embodiment, when the cutting mechanism 400 cuts the paper S, one side S1 of the paper S is pressed against the downstream inclined surface 90B, and the other side S2 of the paper S is pressed against the upstream inclined surface 90A.

[0077] Figure 9 shows another example of the configuration of the side edge removal section 308. In this configuration example shown in Figure 9, the inclined surface 90 is located below the straight line L5 connecting the upstream conveying roll 520 and the cutting conveying roll 430. In this configuration example, of the multiple inclined surfaces 90, the upstream inclined surface 90A, located on the upstream side, is positioned on one side S1 of the paper being transported, and the downstream inclined surface 90B, located on the downstream side, is positioned on the other side S2 of the paper S. In this configuration example, when the cutting mechanism 400 cuts the paper S, one side S1 of the paper S is pressed against the upstream inclined surface 90A, and the other side S2 of the paper S is pressed against the downstream inclined surface 90B.

[0078] Figures 10(A) and (B) show other configuration examples of the side edge removal section 308. In this configuration example, the pressing portion 510 is located downstream of the cutting mechanism 400 in the paper transport direction of the paper S. As in this example configuration, even when the pressing portion 510 is located downstream of the cutting mechanism 400, the distortion of the paper S is reduced, and the cutting mechanism 400 performs cutting on the paper S in a state of reduced distortion. In this configuration example, the cutting transport roll 430, which functions as a pressing means, transports the paper S toward the inclined surface 90 located downstream of the cutting mechanism 400, and presses the surface of the paper S against this inclined surface 90, which is the pressing part 510. As a result, the distortion of the paper S is reduced, as described above.

[0079] In the configuration example shown in Figure 10(A), multiple inclined surfaces 90 are provided. These multiple inclined surfaces 90 are arranged so that their positions in the paper transport direction are different from each other, as described above. Furthermore, in this configuration example, the inclined surface 90 is positioned above the extension of the straight line L5 connecting the upstream transport roll 520 and the cutting transport roll 430. In this configuration example as well, when the cutting mechanism 400 cuts the paper S, the paper S is pressed against multiple inclined surfaces 90. Specifically, in this configuration example, when the cutting mechanism 400 cuts the paper S, the other side S2 of the paper S is pressed against the upstream inclined surface 90A, and the other side S1 of the paper S is pressed against the downstream inclined surface 90B.

[0080] Figure 10(B) shows another example of the configuration of the side edge removal section 308. In this configuration example as well, the contact portion 510 is positioned downstream of the cutting mechanism 400 in the transport direction of the transported paper S. In this configuration example as well, the cutting transport roll 430, which functions as a pressing means, transports the paper S toward the inclined surface 90 and presses the surface of the paper S against this inclined surface 90, which is the pressing part 510. As a result, the distortion of the paper S is reduced, as described above.

[0081] In this configuration example shown in Figure 10(B), multiple inclined surfaces 90 are provided. These multiple inclined surfaces 90 are arranged so that their positions in the paper transport direction are different from each other, as described above. Furthermore, in this configuration example, the inclined surface 90 is positioned below the extension of the straight line L5 connecting the upstream transport roll 520 and the cutting transport roll 430.

[0082] In this configuration example as well, when the cutting mechanism 400 cuts the paper S, the paper S is pressed against multiple inclined surfaces 90. Specifically, in this configuration example, when the cutting mechanism 400 cuts the paper S, one side S1 of the paper S is pressed against the upstream inclined surface 90A, and the other side S2 of the paper S is pressed against the downstream inclined surface 90B.

[0083] In the configuration example shown in Figures 8 and 9, the transport speed of the paper S by the upstream transport roll 520 may be greater than the transport speed by the cutting transport roll 430. In this case, both the contact pressure between the upstream inclined surface 90A and the paper S, and the contact pressure between the downstream inclined surface 90B and the paper S can be increased. Furthermore, in the configuration examples shown in Figures 8 and 9, the transport speed of the paper S by the upstream transport roll 520 may be equal to the transport speed of the cutting transport roll 430. Furthermore, in the configuration example shown in Figures 8 and 9, the transport speed of the paper S by the cutting transport roll 430 may be greater than the transport speed by the upstream transport roll 520. In this case, contact between the downstream inclined surface 90B and the paper S becomes less likely, but the contact pressure between the upstream inclined surface 90A and the paper S can be increased.

[0084] Furthermore, while Figures 8 to 10 illustrate the case where the paper S is pressed against multiple inclined surfaces 90, multiple inclined surfaces 90 are not essential. The paper S may be cut by the cutting mechanism 400 even when it is pressed against only one inclined surface 90. Furthermore, in the configuration example shown in Figure 6, the case where the pressed portion 510 is located upstream of the cutting mechanism 400 was described as an example, but this pressed portion 510 may also be located downstream of the cutting mechanism 400. Furthermore, the pressing portion 510 may be provided both upstream and downstream of the cutting mechanism 400.
