DETAILED DESCRIPTION OF THE INVENTION

[0010] <Embodiment> A sheet processing apparatus and a control method for the sheet processing apparatus according to an embodiment of the present invention will be described below with reference to the drawings. The sheet processing apparatus 1 shown in FIG. 1 performs a counting and sorting process in which sheets S are counted and sorted, and a counting and bundling process in which sheets S are counted and bundled. Specifically, the sheet processing apparatus 1 processes banknotes as the sheets S. In the counting and sorting process, the sheet processing apparatus 1 classifies inserted sheets S into count-target sheets S that are to be counted and rejected sheets S that are not to be counted, and further counts and classifies the count-target sheets S by type and stores them. In the counting and bundling process, the sheet processing apparatus 1 classifies inserted sheets S into bundling-target sheets S that are to be bundled and rejected sheets S that are not to be bundled, and accumulates and bundles the bundling-target sheets S in groups of a predetermined number to form bundled sheets. In the following description, "front" refers to the operator's side of the paper sheet processing device 1, "rear" refers to the opposite side from the operator of the paper sheet processing device 1, "right" refers to the right side as seen from the operator of the paper sheet processing device 1, and "left" refers to the left side as seen from the operator of the paper sheet processing device 1.

[0011] The sheet processing device 1 of this embodiment is configured by connecting, in this order from the right, a sheet counting device 2, a sheet stacking device 3, and a sheet bundling device 4. The sheet processing device 1 can also be provided with an evacuation pocket section 5 at the left end of the sheet processing device 1, i.e., on the left side of the sheet bundling device 4.

[0012] [Paper sheet counting device 2] The paper sheet counting device 2 has an input port 11 that is located from the middle to the bottom in the vertical direction on the right side of the device and is always open to the outside of the paper sheet counting device 2 across the right side and front, and a reject section 12 that is located above the input port 11 on the right side of the device and is always open to the outside of the paper sheet counting device 2 across the right side and front.

[0013] A plurality of paper sheets S are set in the input port 11 in a state where they are stacked vertically with their long sides aligned front to back and their short sides aligned left to right. The input port 11 separates and feeds out the stacked paper sheets S set in this manner, one by one, starting from the bottom, and takes them into the paper sheet counting device 2. The paper sheets S fed out from the input port 11 move in the direction in which their short sides extend. The paper sheets S move inside the paper sheet processing device 1 with their long sides aligned front to back.

[0014] Inside the paper sheet counting device 2, there are provided an in-counting device conveying section 21 that conveys paper sheets S fed out from the insertion port 11, and a recognition section 22 that recognizes and counts the paper sheets S being conveyed by the in-counting device conveying section 21. The paper sheets S conveyed by the in-counting device conveying section 21 move along the extension direction of their short sides. The recognition section 22 recognizes the conveying state and type of the paper sheets S, such as their denomination.

[0015] The counting-device transport unit 21 has a left extension portion 21a extending from the insertion slot 11 toward the left side of the paper sheet counting device 2, an upward extension portion 21b extending upward from an end portion of the left extension portion 21a near the left side, a left extension portion 21c extending from the upper end of the upward extension portion 21b toward the left side of the paper sheet counting device 2 and opening on the left side, and a branch extension portion 21d extending from the upper end of the upper extension portion 21b toward the right side of the paper sheet counting device 2 and connected to the reject unit 12. The counting-device transport unit 21 has a recognition unit 22 provided on the upward extension portion 21b that extends along the vertical direction. The reject unit 12 receives paper sheets S from the branch extension portion 21d of the counting-device transport unit 21 and stacks the fed paper sheets S from bottom to top.

[0016] An operation display unit 25 that receives operation inputs and displays information is provided on the front surface of the sheet counting device 2. The sheet counting device 2 also includes a control unit 26 that controls the sheet counting device 2, the sheet stacking device 3 connected to the sheet counting device 2, and the sheet bundling device 4, i.e., the entire sheet processing device 1, and a memory unit 27 that stores master data that serves as a basis for recognition, data on the recognition and counting results, etc.

[0017] [Paper sheet stacking device 3] Inside the paper sheet stacking device 3, there is provided an in-stacking device transport section 31 that is connected to the left extension section 21c of the paper sheet counting device 2 and transports the paper sheets S fed from the left extension section 21c. The paper sheets S transported by the in-stacking device transport section 31 also move along the extension direction of their short sides.

[0018] The in-stacking device transport section 31 has a connecting transport section 31A that opens at the top of the right side of the paper sheet stacking device 3 and extends horizontally and linearly toward the left side of the paper sheet stacking device 3, opening at the top of the left side, and a branching transport section 31B that branches off downward from the left side of the connecting transport section 31A. The connecting transport section 31A and the branching transport section 31B each have their own drive motors and can be driven independently.

[0019] The branching conveying section 31B branches off from the left side of the connecting conveying section 31A and extends vertically downward, and has a terminal end opposite the connecting conveying section 31A, which has a downward extending section 31Ba extending toward the right side of the paper sheet stacking device 3, and multiple, specifically three, branching extending sections 31Bb branching off from an intermediate position of the downward extending section 31Ba and extending toward the right side of the paper sheet stacking device 3. A stacking section 32 is connected to the terminal end of the downward extending section 31Ba and the terminal end of the three branching extending sections 31Bb, respectively. Thus, the paper sheet stacking device 3 is provided with multiple, specifically four, stacking sections 32. All of the stacking sections 32 are always open to the outside of the paper sheet stacking device 3 from the front side of the paper sheet stacking device 3.

[0020] The multiple stacking units 32 all have the same configuration, and each have a bottom 35 that slopes downward to the right with respect to the horizontal, and a support wall 36 that extends upward from the right end of the bottom 35, perpendicular to the bottom 35. At the end of the bottom 35 of each stacking unit 32 opposite the support wall 36, there is provided a bladed wheel 37 that is provided at each end position of the branching conveying unit 31B and feeds out paper sheets S into the stacking unit 32. The bladed wheels 37 rotate together with the paper sheets S conveyed by the branching conveying unit 31B, sandwiching them between their blades. When the paper sheets S come into contact with the bottom 35 and come out from between the blades, the blades push the paper sheets S toward the support wall 36. As a result, the paper sheets S are stacked in order on the support wall 36, standing on the bottom 35 with their short sides aligned vertically.

[0021] Here, the above-mentioned counting and sorting process is possible in the paper sheet processing device 1 as a process using the paper sheet counting device 2 and the paper sheet stacking device 3. The counting and sorting process is a process in which the paper sheets S set in a stacked state in the inlet 11 of the paper sheet counting device 2 are counted while being recognized by the recognition unit 22 of the paper sheet counting device 2, and the paper sheets S to be counted and sorted are stacked in the multiple stacking units 32 of the paper sheet stacking device 3 while being classified.

[0022] When an operation to select the counting and sorting process is input on the operation and display unit 25, the control unit 26 is configured to set, on the operation and display unit 25, the types of paper sheets S to be subjected to the sorting and counting process to be stored in each stacking unit 32. For example, the first stacking unit 32, one of the plurality of stacking units 32, is configured to store 10,000 yen notes as paper sheets S after counting by the recognition unit 22, the second stacking unit 32 is configured to store 5,000 yen notes as paper sheets S after counting by the recognition unit 22, the third stacking unit 32 is configured to store 1,000 yen notes as paper sheets S after counting by the recognition unit 22, and the fourth stacking unit 32 is configured to store 2,000 yen notes as paper sheets S after counting by the recognition unit 22.

[0023] When paper sheets S are set in a stacked state in the input port 11 and an operation to start the counting and sorting process is input to the operation display unit 25, the control unit 26 separates the stacked paper sheets S set in the input port 11 one by one and transports them by the left extension unit 21a and the upper extension unit 21b of the counting device transport unit 21. Then, the control unit 26 causes the recognition unit 22 to recognize the paper sheets S while they are being transported by the upper extension unit 21b. If the recognition result of the recognition unit 22 identifies the paper sheets S as reject paper sheets S that are not subject to the counting and sorting process and include paper sheets S with identification errors such as counterfeit notes, damaged notes, and notes with tape attached, the control unit 26 does not count the paper sheets S and transports them from the upper extension unit 21b to the branch extension unit 21d to the reject unit 12 for storage.

[0024] Furthermore, when the recognition result of the recognition unit 22 identifies a paper sheet S as being subject to counting and sorting processing, the control unit 26 adds up the count value of the type of paper sheet S, i.e., its denomination, and transports the paper sheet S to the collection unit 32 corresponding to its type and stores it therein using the upward extension unit 21b, the left extension unit 21c, the connecting conveying unit 31A and the branching conveying unit 31B of the conveying unit 31 within the paper sheet collection device 3.

[0025] In this way, the sheet processing device 1 sorts and stores the sheets S to be counted and sorted among the sheets S set in an accumulated state in the inlet 11 of the sheet counting device 2 into the plurality of stacking sections 32 of the sheet stacking device 3. Note that a sensor may be provided to detect that a sheet S has been set in the inlet 11, and the counting and sorting process may be started automatically when this sensor detects the sheet S.

[0026] [Paper sheet binding device 4] Inside the paper sheet bundling device 4, there is provided an in-bundling-device conveying section 41 that is connected to the connecting conveying section 31A of the paper sheet stacking device 3 and conveys the paper sheets S fed out from the connecting conveying section 31A. The paper sheets S conveyed by the in-bundling-device conveying section 41 also move along the extension direction of their short sides.

[0027] The in-bundling-device conveying section 41 has a connected conveying section 41A that opens at the top of the right side of the paper sheet bundling device 4 and is connected to the connecting conveying section 31A, extends horizontally and linearly toward the left side of the paper sheet bundling device 4, and opens at the top of the left side and is connected to the inside of the evacuation pocket section 5 when the evacuation pocket section 5 is provided, and a branched conveying section 41B that branches off downward from the left side of the connected conveying section 41A. The connected conveying section 41A and the branched conveying section 41B each have their own drive motor and can be driven independently.

[0028] The branching conveying section 41B branches off from the left side of the connecting conveying section 41A and extends vertically downward, and has an end opposite to the connecting conveying section 41A, which has a downward extending section 41Ba extending toward the right side of the paper sheet bundling device 4, and a branching extending section 41Bb branching from an intermediate position of the downward extending section 41Ba and extending toward the right side of the paper sheet bundling device 4. A stacking mechanism 42 is connected to each of the end of the downward extending section 41Ba and the end of the branching extending section 41Bb. Thus, the paper sheet bundling device 4 is provided with a plurality of stacking mechanisms 42, specifically, two stacking mechanisms 42.

[0029] Here, the counting and bundling process described above is a process that uses the sheet counting device 2, the sheet stacking device 3, and the sheet bundling device 4 in the sheet processing device 1. The counting and bundling process is a process of bundling sheets S to be bundled from among the sheets S set in a stacked state in the inlet 11 of the sheet counting device 2.

[0030] When an operation to select the counting and bundling process is input on the operation display unit 25, the control unit 26 causes the paper sheets S to be bundled to be set on the operation display unit 25. For example, 10,000 yen banknotes, which are Japanese currency, are set as the paper sheets S to be bundled.

[0031] When paper sheets S are set in a stacked state in the input port 11 and a start operation for the counting and bundling process is input to the operation display unit 25, the control unit 26 separates the stacked paper sheets S set in the input port 11 one by one and transports them by the left extension unit 21a and the upper extension unit 21b of the counting device transport unit 21. Then, the control unit 26 causes the recognition unit 22 to recognize the paper sheets S while they are being transported by the upper extension unit 21b. If the recognition result of the recognition unit 22 identifies the paper sheets S as being counterfeit, damaged, taped, or other paper sheets with an identification error, the control unit 26 does not count the paper sheets S and transports them from the upper extension unit 21b to the branch extension unit 21d to the reject unit 12 for storage.

[0032] Furthermore, when the recognition result of the recognition unit 22 indicates that the paper sheet S is a normally recognized paper sheet S of a different denomination that is not to be bundled, the control unit 26 also transports this paper sheet S from the upward extension unit 21b to the branch extension unit 21d and stores it in the reject unit 12. Here, the paper sheet S that has been identified as a normally recognized paper sheet S of a different denomination that is not to be bundled can also be transported to a predetermined stacking unit 32 and stored therein by the upward extension unit 21b, the left extension unit 21c, the connecting conveying unit 31A and the branching conveying unit 31B of the in-stacking-device conveying unit 31 of the paper sheet stacking device 3. In other words, the destination for storing the normally recognized paper sheet S of a different denomination that is not to be bundled can be selected from the reject unit 12 and multiple stacking units 32.

[0033] Furthermore, when the recognition result of the recognition unit 22 identifies the paper sheet S as a paper sheet S to be bundled, the control unit 26 causes the upward extension unit 21b, the left extension unit 21c, the connecting conveying unit 31A of the paper sheet stacking device 3, the connecting conveying unit 41A and the branching conveying unit 41B of the paper sheet bundling device 4 to transport the paper sheet S to the stacking mechanism 42, where it is stored in units of the number of sheets to be bundled (specifically, 100 sheets). In the counting and bundling process, the control unit 26 first causes the downward extension 41Ba and branch extension 41Bb of the connecting conveying unit 41A and the branching conveying unit 41B to accumulate the bundled number of sheets S in the upper one of the two accumulation mechanisms 42, then causes the downward extension 41Ba of the connecting conveying unit 41A and the branching conveying unit 41B to accumulate the bundled number of sheets S in the lower accumulation mechanism 42, and then causes the downward extension 41Ba of the connecting conveying unit 41A and the branching conveying unit 41B to accumulate the bundled number of sheets S in the accumulation mechanism 42 above the downward extension 41Ba and branch extension 41Bb of the connecting conveying unit 41A and the branching conveying unit 41B, so that the sheets S are alternately accumulated by the bundled number in the two accumulation mechanisms 42. Note that a sensor that detects that sheets S have been set in the insertion slot 11 may be provided, and the counting and bundling process may be started automatically when this sensor detects sheets S.

[0034] The stacking mechanism 42 aligns the positions of the short sides of the sheets S sequentially discharged to the right from the connected one of the downward extension portion 41Ba and the branch extension portion 41Bb of the branching conveying section 41B by abutting the long sides of the right ends of the sheets S against a positioning wall portion (not shown) extending perpendicular to the left-right direction. At the same time, the stacking mechanism 42 aligns the positions of the long sides of the sequentially discharged sheets S by simultaneously tapping both short sides with tapping mechanisms (not shown) provided on both sides of the long sides of the sheets S. The stacking mechanism 42 stacks the sequentially discharged sheets S from bottom to top while aligning the positions of their short sides and long sides.

[0035] Here, the tapping mechanisms on both sides of the accumulation mechanism 42 (not shown) each stroke toward the paper sheet S to a position corresponding to the long side length of the paper sheet S to be bundled, which was set when the counting and bundling process began, and position the long side position of the paper sheet S so that the center position in the long side direction is located at a predetermined reference position in the front-to-back direction within the paper sheet bundling device 4, regardless of the long side length of the paper sheet S to be bundled. That is, the stroke amount of the tapping mechanisms (not shown) on both sides of the accumulation mechanism 42 toward the paper sheets S when the paper sheets S to be bundled have a longer long side length than the paper sheets S of one long side length is shorter than the stroke amount toward the paper sheets S when the paper sheets S to be bundled have a longer long side length than the paper sheets S of one long side length, and the stroke amount toward the paper sheets S when the paper sheets S to be bundled have a shorter long side length than the paper sheets S of one long side length is longer, and in either case, the paper sheets S are positioned so that the center position in the long side direction is located at a predetermined reference position in the front-to-rear direction.

[0036] The paper sheet bundling device 4 has a transport mechanism 45 that transports the stacked paper sheets SS when 100 sheets, the number of sheets S bundled, are stacked in one of the plurality of stacking mechanisms 42 to form stacked paper sheets SS, and that transports the stacked paper sheets SS when 100 sheets, the number of sheets S bundled, are stacked in the other of the plurality of stacking mechanisms 42 to form stacked paper sheets SS. The transport mechanism 45 has gripping units 46 that grip the stacked paper sheets SS, which have been stacked vertically in the stacking mechanism 42 with their short sides and long sides aligned, from both above and below, a gripping operation drive mechanism (not shown) that causes the gripping units 46 to perform gripping and release operations, and a gripping unit movement drive mechanism (not shown) that moves the gripping units 46. Here, the long sides of the sheets S constituting the stacked sheets SS are also the long sides of the stacked sheets SS, and the short sides of the sheets S constituting the stacked sheets SS are also the short sides of the stacked sheets SS.

[0037] In the transport mechanism 45, the gripping unit 46 grips the stacked paper sheets SS, which have been bundled and stacked in the stacking mechanism 42, pulls them out to the right from the stacking mechanism 42, moves vertically downward, and then moves left to transport them. At this time, the gripping unit 46 grips the stacked paper sheets SS at a position a predetermined distance in the short side direction from the long side at the right end, regardless of the length of the short side. In addition, the gripping unit 46 transports the stacked paper sheets SS while maintaining the center position in the long side direction at the reference position in the front-to-rear direction.

[0038] The sheet bundling device 4 has a bundling and discharging mechanism 51 that is provided below and to the left of the conveying mechanism 45, and that receives stacked sheets SS from the gripping unit 46 that has moved leftward after descending as described above, bundles them, and discharges them to the outside of the sheet bundling device 4. In other words, the bundling and discharging mechanism 51 bundles the stacked sheets SS conveyed by the conveying mechanism 45 and discharges them to the outside of the sheet bundling device 4. The bundling and discharging mechanism 51 has a sending-out mechanism (not shown) that receives the stacked sheets SS from the gripping unit 46 and sends them out forward, a bundling mechanism 52 that bundles the stacked sheets SS sent out by the sending-out mechanism to form bundled sheets, and a discharging mechanism (not shown) that discharges the bundled sheets after being bundled by the bundling mechanism 52 to the outside of the sheet bundling device 4 from a bundling outlet 55 provided on the front of the sheet bundling device 4. Here, as shown in Figure 2, the bundling mechanism 52 and the release mechanism (not shown) are incorporated into the same unit 57, and this unit 57 can be pulled out from the device body 58 of the paper sheet bundling device 4 as shown in Figure 2 when the front cover (not shown) of the paper sheet bundling device 4 is open.

[0039] 3, the bundling mechanism 52 has a supply unit 61 that supplies a band-shaped, i.e., tape-shaped, binding medium T, a printer 62 (writing unit) that prints letters and symbols on the binding medium T supplied by the supply unit 61 to write predetermined descriptions, and a bundling unit 63 that forms a bundle of paper sheets by wrapping the binding medium T supplied by the supply unit 61 and on which the predetermined descriptions have been written by the printer 62 around a stack of paper sheets SS. The printer 62 can be a dot matrix printer, a color inkjet printer, a monochrome inkjet printer, or the like that uses the feeding of the binding medium T sent by the supply unit 61 to print. Here, an example in which a dot matrix printer is used will be described.

[0040] 2, the supply unit 61 has a roll-shaped holding unit 70 that holds a roll-shaped part RT of the binding medium T wound into a roll, and pulls out the binding medium T from this roll-shaped holding unit 70 and pulls the binding medium T back toward the roll-shaped holding unit 70. Here, the binding medium T is pulled out to the right from the top of the roll-shaped part RT.

[0041] As shown in Figure 3, the supply section 61 has an entrance side conveying roller 71, an entrance side clamping roller 72, a guide roller 73, a rear side conveying roller 74, a rear side clamping roller 75, an entrance side media detection sensor 76, an intermediate media detection sensor 77, and a supply drive mechanism not shown.

[0042] The entrance-side conveying rollers 71 are driven by a supply drive mechanism (not shown) to rotate forward and reverse. When rotating forward, the entrance-side conveying rollers 71 pull out and feed the binding medium T extending from the roll-shaped holding unit 70 (shown in FIG. 2) provided on the left side while clamping it between the entrance-side clamping rollers 72. Feed in this direction is called forward feed. When rotating reverse, the entrance-side conveying rollers 71 return the binding medium T, clamped between the entrance-side clamping rollers 72, to the roll-shaped holding unit 70 (shown in FIG. 2). Feed in this direction is called reverse feed.

[0043] The guide roller 73 is provided between the roll-shaped holding section 70 shown in Figure 2 and the entrance side conveying roller 71 and the entrance side clamping roller 72 shown in Figure 3, and guides the underside of the binding medium T pulled out from the roll-shaped holding section 70 by the entrance side conveying roller 71 and the entrance side clamping roller 72.

[0044] The rear-side conveying rollers 74 are driven by a supply drive mechanism (not shown) to rotate forward and reverse. When rotating forward, the rear-side conveying rollers 74 convey the binding medium T sent out from the entrance-side conveying rollers 71 and the entrance-side clamping rollers 72 in a state where the binding medium T is sandwiched between the rear-side clamping rollers 75 and sent to the opposite side of the entrance-side conveying rollers 71 and the entrance-side clamping rollers 72. Feed in this direction is called forward feed. When rotating reverse, the rear-side conveying rollers 74 return the binding medium T, sandwiched between the rear-side clamping rollers 75, to the entrance-side conveying rollers 71 and the entrance-side clamping rollers 72. Feed in this direction is called reverse feed.

[0045] The entrance-side conveying rollers 71 and the rear-side conveying rollers 74 are driven by a supply drive mechanism (not shown) and rotate synchronously in the same direction at a constant speed. An intermediate guide (not shown) that guides the binding medium T is provided between the entrance-side conveying rollers 71 and the entrance-side clamping rollers 72 and the rear-side conveying rollers 74 and the rear-side clamping rollers 75. This intermediate guide guides the binding medium T, which is fed forward to the right from the entrance-side conveying rollers 71 and the entrance-side clamping rollers 72, downward and then to the left at a lower position, so that it is clamped from the right side by the rear-side conveying rollers 74 and the rear-side clamping rollers 75.

[0046] The entrance-side medium detection sensor 76 is provided adjacent to the guide roller 73 side of the entrance-side conveying roller 71 and the entrance-side clamping roller 72, i.e., on the upstream side in the forward feed direction, and has a light-emitting element and a light-receiving element. The entrance-side medium detection sensor 76 detects the presence or absence of binding medium T passing between the light-emitting element and the light-receiving element based on whether or not light is blocked.

[0047] The intermediate medium detection sensor 77 is provided adjacent to the rear conveying rollers 74 and rear clamping rollers 75 on the opposite side from the entrance conveying rollers 71 and entrance clamping rollers 72, i.e., downstream in the forward feed direction of the rear conveying rollers 74 and rear clamping rollers 75, and has a light-emitting element and a light-receiving element. The intermediate medium detection sensor 77 detects the presence or absence of binding medium T passing between the light-emitting element and the light-receiving element based on whether or not light is blocked.

[0048] The printer 62 is provided between the entrance-side conveying rollers 71 and the entrance-side clamping rollers 72 and the rear-side conveying rollers 74 and the rear-side clamping rollers 75. The printer 62 prints from the right side on the binding medium T guided by an intermediate guide unit (not shown).

[0049] The binding section 63 has a pair of arc-shaped inner guide sections 81 and an upper inner guide section 82 that guide the binding medium T fed forward by the rear conveying roller 74 and the rear clamping roller 75 so that it becomes a horizontally elongated, approximately elliptical shape.

[0050] The pair of arc-shaped inner guide portions 81 are arranged on the left and right at a distance from each other, and have arc shapes that convex in opposite directions.

[0051] The upper inner guide portion 82 is disposed substantially horizontally between the upper ends of the pair of arc-shaped inner guide portions 81 .

[0052] Outer guide portions (not shown) are provided radially outward of the pair of arc-shaped inner guide portions 81 and above the upper inner guide portion 82, and together with these, guide the binding medium T so that it forms a substantially elliptical shape. The pair of arc-shaped inner guide portions 81, the upper inner guide portion 82, and the outer guide portion (not shown) guide the binding medium T, which is fed forward to the left by the rear conveying roller 74 and the rear clamping roller 75, upward, then to the right, further downward, and then to the left. When finally guiding it to the left, the pair of arc-shaped inner guide portions 81, the upper inner guide portion 82, and the outer guide portion (not shown) guide the binding medium T so that the leading end side is radially inward relative to the trailing end side.

[0053] The pair of arc-shaped inner guide portions 81 and upper inner guide portions 82 are movable in the front-to-rear direction and are driven by an inner guide portion drive mechanism (not shown) to move in the front-to-rear direction. In the forward position at the front end, they guide the binding medium T fed by the rear conveying rollers 74 and rear clamping rollers 75, and in the backward position at the rear end, they retreat behind the binding medium T. The pair of arc-shaped inner guide portions 81 and upper inner guide portions 82 are in a standby state when in the forward position.

[0054] The bundling unit 63 has an outlet-side media detection sensor 85 at the leading end of the arc-shaped inner guide portion 81 in the forward feed direction of the bundling medium T, which detects the leading end of the forward feed direction of the bundling medium T guided by the pair of arc-shaped inner guide portions 81, the upper inner guide portion 82, and the outer guide portion (not shown). The outlet-side media detection sensor 85 has a light-emitting element and a light-receiving element, and detects the presence or absence of bundling medium T passing between the light-emitting element and the light-receiving element based on whether or not light is blocked.

[0055] The binding unit 63 has a chuck unit 91 , a pressing unit 92 , a band fixing unit 94 , a cutter unit 95 , a band holding unit 96 , and a heater unit 97 .

[0056] The stacked paper sheets SS sent forward by a sending mechanism (not shown) are placed on the chuck unit 91. The chuck unit 91 has a first chuck unit 101, a second chuck unit 102, and a band detection mechanism 103.

[0057] The first chuck portion 101 has a chuck base portion 111 and a cover portion 112 . When the stacked paper sheets SS are sent forward by a sending mechanism (not shown), the stacked paper sheets SS are placed on the chuck base portion 111. The chuck base portion 111 is fixed in position in the unit 57 and has a pair of inclined support portions 121 and a connecting portion 122. The pair of inclined support portions 121 are mirror-symmetrical in the left-right direction. The upper surfaces of the pair of inclined support portions 121 are inclined relative to the horizontal so that the height position decreases as the distance between them increases in the left-right direction. The connecting portion 122 connects the lower portions of the pair of inclined support portions 121.

[0058] The cover part 112 has a substantially flat plate shape and is disposed substantially horizontally below the chuck base part 111. The cover part 112 is fixed in position in the unit 57 and is disposed so as to provide a gap between it and the chuck base part 111 in the vertical direction.

[0059] The second chuck portion 102 has a pair of adjustment plates 125 and an adjustment drive mechanism (not shown). The pair of adjustment plates 125 are plate-shaped members and are provided between the chuck base portion 111 and the cover portion 112. The pair of adjustment plates 125 are movable in the left-right direction. The pair of adjustment plates 125 are driven by an adjustment drive mechanism (not shown) to move uniformly toward each other or move uniformly away from each other. The distance between the pair of adjustment plates 125 is adjusted according to the type of stacked paper sheets SS to be bundled.

[0060] The band detection mechanism 103 has a band detection member 128 that can be raised and lowered and is located below the adjustment plate 125 on the downstream side of the forward feed direction of the binding medium T, i.e., the left side, of the pair of adjustment plates 125, and a band detection sensor (not shown) that detects the up and down movement of the band detection member 128.

[0061] The pressing portion 92 has a pair of pressing pieces 131 and a pressing drive mechanism (not shown). The pair of pressing pieces 131 are mirror-symmetrical in the left-right direction.

[0062] The pair of pressing pieces 131 are disposed vertically above the pair of inclined support portions 121 of the chuck base portion 111. The lower surfaces of the pair of pressing pieces 131 are inclined in the same direction as the upper surfaces of the pair of inclined support portions 121. In other words, the lower surfaces of the pair of pressing pieces 131 are inclined relative to the horizontal so that the vertical positions of the lower surfaces of the pair of pressing pieces 131 become lower as they move apart from each other in the left-right direction.

[0063] The pair of pressing pieces 131 can be raised and lowered together, and are driven by a pressing drive mechanism (not shown) to raise and lower the pressing unit 92. The pressing unit 92 is in a standby state when the pair of pressing pieces 131 are positioned at the upper limit position where they are furthest above the chuck unit 91.

[0064] In a standby state in which the pressing unit 92 positions the pair of pressing pieces 131 at the upper limit position, a feed mechanism (not shown) transfers the stacked paper sheets SS forward. Then, the stacked paper sheets SS are placed on the chuck base portion 111 in a state in which the center position in the short side direction, i.e., the left-right direction, of the stacked paper sheets SS coincides with the center position in the left-right direction of the chuck base portion 111 of the first chuck unit 101. The bundling mechanism 52 bundles the stacked paper sheets SS placed on the first chuck unit 101 in this manner.

[0065] With the stacked paper sheets SS placed on the chuck base 111, the pressing unit 92 is driven by a pressing drive mechanism (not shown) to lower the pair of pressing pieces 131. As a result, the pair of pressing pieces 131 and the pair of inclined support parts 121 of the chuck base 111 clamp the stacked paper sheets SS from above and below. As a result, the stacked paper sheets SS are deformed into a mirror-symmetrical, approximately inverted V-shape in which the left side of the center in the short side direction, i.e., the left-right direction, slopes downward to the left, and the right side of this center slopes downward to the right.

[0066] The band fixing unit 94 has a band fixing member 141 and a band fixing drive mechanism (not shown). The band fixing member 141 is a plate-shaped member that extends perpendicularly to the left-right direction. The band fixing member 141 is disposed vertically below the adjustment plate 125 on the right side of the second chuck portion 102. The band fixing member 141 has a passage hole 142 that penetrates in the left-right direction a predetermined distance downward from the top surface. The passage hole 142 is wide enough to allow the binding medium T to pass through. The band fixing member 141 is driven by a band fixing drive mechanism (not shown) to move up and down. When the band fixing member 141 is in a standby state located at the lowest position, the binding medium T that is fed forward by the rear conveying roller 74 and rear clamping roller 75 of the supply unit 61 enters the passage hole 142. Thereafter, the binding medium T being fed forward passes under the cover portion 112 of the chuck portion 91, a pair of adjustment plates 125 and the band detection member 128, is guided by a pair of arc-shaped inner guide portions 81, an upper inner guide portion 82 and an outer guide portion not shown, passes between the light-emitting element and light-receiving element of the outlet side medium detection sensor 85, and is inserted between the band fixing member 141 and the adjustment plate 125 and cover portion 112 on the right side of the second chuck portion 102.

[0067] The cutter unit 95 has a cutter 145 and a cutter drive mechanism (not shown). The cutter 145 is provided near the left side of the band fixing member 141. The cutter 145 is driven by a cutter drive mechanism (not shown) to move up and down linearly while remaining positioned near the left side of the band fixing member 141. The cutter unit 95 cuts the binding medium T inserted in the passage hole 142 of the band fixing member 141 by raising the cutter 145 with the cutter drive mechanism (not shown). The cutter unit 95 is in a standby state when it is positioned at its lowest position relative to the band fixing member 141.

[0068] The band presser section 96 has a band presser member 151 and a band presser drive mechanism (not shown). The band pressing member 151 is provided below the cover portion 112 of the chuck portion 91 , the pair of adjustment plates 125 and the band detecting member 128 , and has a pressing member main body 152 and a support shaft 153 .

[0069] The support shaft 153 is provided to the left of the band fixing member 141 and the cutter 145, and is fixed in position relative to the unit 57. The support shaft 153 extends in the front-to-rear direction. The pressing member body 152 is a plate-shaped member and is arranged above the support shaft 153. The pressing member body 152 extends along the support shaft 153. The band pressing member 151 is in a standby state when the right end of the pressing member body 152, i.e., the upstream side in the forward feed direction of the binding medium T, is lower than the left end, i.e., the downstream side in the forward feed direction of the binding medium T.

[0070] The band presser drive mechanism (not shown) rotates the presser member body 152 around the support shaft 153 so as to raise and lower the right end of the presser member body 152. When the band presser drive mechanism (not shown) raises the right end of the presser member body 152 of the band presser member 151 in a standby state, the right end of the band presser member 151 clamps the binding medium T between itself and the cover portion 112.

[0071] The heater section 97 has a heater main body 161 and a heater lifting / lowering drive mechanism (not shown). The heater main body 161 is inclined upward to the right, and the upper surface thereof extends horizontally. The heater main body 161 generates heat mainly from the upper surface.

[0072] A heater lifting / lowering mechanism (not shown) drives the heater main body 161 to rise linearly to the upper right and to fall linearly to the lower left while maintaining the above-mentioned state. The heater main body 161 is in a standby state when positioned at the lowest position. The heater lifting / lowering mechanism (not shown) moves the heater main body 161 toward the cover part 112 when it is raised. The heater main body 161 raised by the heater lifting / lowering mechanism (not shown) is sandwiched between the band presser member 151 and the cover part 112, as described below. The rear end and leading end of the cut side of the binding medium T after it has been cut by the cutter 145 are sandwiched between the cover part 112 and heated to thermally bond them.

[0073] Next, the operation of the counting and bundling process for producing bundled paper sheets by the paper sheet processing apparatus 1 will be described.

[0074] For example, when setting or resetting the bundling medium T in the paper sheet processing device 1, the operator opens the front cover (not shown) of the paper sheet bundling device 4 and pulls out the unit 57 including the bundling mechanism 52 forward from the device main body 58 as shown in Fig. 2. In this state, the leading end of the bundling medium T extending from the roll RT held in the roll holding part 70 is passed between the light-emitting element and the light-receiving element of the entrance-side medium detection sensor 76 as shown in Fig. 3, and then inserted between the entrance-side conveying roller 71 and the entrance-side clamping roller 72. In this state, the operator presses the band feed switch 171. The control unit 26 then causes the entrance side conveying roller 71 and the rear side conveying roller 74 to rotate in the forward direction using a supply drive mechanism not shown, causing the binding medium T to be sent to the right by the entrance side conveying roller 71 and the entrance side clamping roller 72 and inserted into the intermediate guide section not shown, and then guided downward by the intermediate guide section, where it is clamped from the right between the rear side conveying roller 74 and the rear side clamping roller 75, sent to the left by the rear side conveying roller 74 and the rear side clamping roller 75, and enters between the light-emitting element and the light-receiving element of the intermediate medium detection sensor 77, and its tip is detected by the intermediate medium detection sensor 77.

[0075] When the intermediate medium detection sensor 77 detects the leading edge of the bundling medium T, the control unit 26 causes the inlet-side conveying rollers 71 and the rear-side conveying rollers 74 to rotate in the reverse direction by a predetermined amount using a supply drive mechanism (not shown), thereby feeding the bundling medium T back toward the roll-shaped holding unit 70, i.e., pulling it back. The control unit 26 then reverses the inlet-side conveying rollers 71 and the rear-side conveying rollers 74 by a predetermined amount and stops them. As a result, as shown in FIG. 4, the leading edge of the bundling medium T is positioned on the rear-side conveying roller 74 and rear-side clamping roller 75 side of the printer 62 in the intermediate guide unit (not shown), i.e., at a predetermined lower position. This state is the standby state of the bundling medium T.

[0076] When performing the counting and bundling process, first, in the sheet processing device 1, the denomination of the bundled sheets to be produced by the bundling process by the sheet bundling device 4 is set. Specifically, as shown in FIG. 1 , an operation to select the counting and bundling process is input on the operation display unit 25 provided in the sheet counting device 2, and the type of sheets S to be counted and bundled, i.e., the type of bundled sheets to be produced, for example, "yen" is selected and input as the currency type, and a denomination of the "yen," for example, 10,000 yen, is selected and input. Then, the control unit 26 provided in the sheet counting device 2 sets this denomination as the denomination of the bundled sheets to be produced. Hereinafter, this set denomination will be referred to as the first denomination.

[0077] The control unit 26 controls the paper sheet bundling device 4 in accordance with the set first denomination. The paper sheet bundling device 4 first moves the pair of adjustment plates 125 of the bundling section 63 by an adjustment drive mechanism (not shown) to a position according to the size of the paper sheets S of the first denomination.

[0078] Next, the sheet processing apparatus 1 performs the following counting and stacking process under the control of the control unit 26. 1, when paper sheets S are set in the input port 11 of the paper sheet counting device 2 and the "start counting and bundling" button on the operation display unit 25 is operated, the input port 11 separates and takes in the set paper sheets S one by one, the left extension 21a and the upper extension 21b of the counting device transport unit 21 transport them, and the recognition unit 22 recognizes and counts them. Note that the paper sheet counting device 2 stops taking in the paper sheets S when the "stop" button on the operation display unit 25 is operated. Note that the paper sheet counting device 2 may be configured so that the input port 11 automatically takes in the paper sheets S when a set detection unit (not shown) provided in the input port 11 detects that paper sheets S have been set in the input port 11.

[0079] The sheet processing apparatus 1 then transports specific sheets S set as targets for bundling among the sheets S determined to be acceptable by the recognition unit 22, i.e., sheets S of the first denomination, to the accumulation mechanism 42 of the sheet bundling device 4 by the upward extension portion 21b and left extension portion 21c of the counting device transport unit 21, the connecting transport portion 31A of the intra-accumulation device transport unit 31 of the sheet stacking device 3, and the connecting transport portion 41A and branching transport portion 41B of the intra-bundling device transport unit 41 of the sheet bundling device 4. On the other hand, the sheet processing apparatus 1 transports sheets S other than the set specific sheets S among the sheets S determined to be acceptable by the recognition unit 22 and sheets S determined to be unacceptable by the recognition unit 22 to the reject unit 12 by the upward extension portion 21b and the branching extension portion 21d and stores them therein.

[0080] In addition, the paper sheet processing device 1 transports paper sheets S that are determined to be unacceptable by the recognition unit 22 to the reject unit 12, while paper sheets S that are determined to be acceptable by the recognition unit 22, other than the specific paper sheets S set to be bundled, may be transported from the upward extension unit 21b and left extension unit 21c of the counting device internal transport unit 21 to a predetermined stacking unit 32 of the paper sheet stacking device by the connecting transport unit 31A and branched transport unit 31B of the stacking device internal transport unit 31 of the paper sheet stacking device 3, and stored therein.

[0081] As described above, the stacking mechanism 42 aligns the positions of the short sides of the sheets S sequentially discharged from the branching conveying section 41B by bringing them into contact with a positioning wall (not shown). At the same time, the stacking mechanism 42 aligns the positions of the long sides of the sheets S sequentially discharged from the branching conveying section 41B by hitting them from both sides with a hitting mechanism (not shown) that strokes in accordance with the length of the long side of the first denomination. As a result, the sheets S are stacked vertically with their long sides and short sides aligned.

[0082] When a predetermined number of sheets S, specifically, for example, 100 sheets, are stacked in the stacking mechanism 42, the sheet bundling device 4 performs the following bundling process under the control of the control unit 26. The number of sheets to be bundled can be variably set within a predetermined range, such as 100 to 125 sheets.

[0083] In the bundling process, the control unit 26 first causes the gripping unit 46 of the transport mechanism 45 to grip the stacked paper sheets SS stacked in the stacking mechanism 42, move them downward, and then transport them further to the left.

[0084] In parallel with the transport of the stacked paper sheets SS, the control unit 26 drives a supply drive mechanism (not shown) of the supply unit 61 shown in FIG. 4 to rotate the entrance-side transport rollers 71 and the rear-side transport rollers 74 in the forward direction. The bundling medium T, which has been in a standby state, is then fed forward by the entrance-side transport rollers 71 and the entrance-side clamping rollers 72 toward the rear-side transport rollers 74 and the rear-side clamping rollers 75. The bundling medium T is guided by an intermediate guide (not shown) and is thereby clamped between the rear-side transport rollers 74 and the rear-side clamping rollers 75, as shown in FIG. 5. The rear-side transport rollers 74 and the rear-side clamping rollers 75 then insert the bundling medium T between the light-emitting element and the light-receiving element of the intermediate medium detection sensor 77. Even after the intermediate medium detection sensor 77 detects the leading edge of the bundling medium T, the control unit 26 further rotates the entrance-side transport rollers 71 and the entrance-side clamping rollers 72 and the rear-side transport rollers 74 and the rear-side clamping rollers 75 in the forward direction. Then, the binding medium T is inserted into the passage hole 142 of the band fixing member 141 in the standby position, and then passes between the chuck portion 91, the band presser member 151 of the band presser portion 96, and the heater main body portion 161 of the heater portion 97, and is guided by the pair of arc-shaped inner guide portions 81, the upper inner guide portion 82, and an outer guide portion (not shown), and proceeds in a circular motion around the outside of the pair of arc-shaped inner guide portions 81 and the upper inner guide portion 82. When the leading end of the binding medium T enters between the light-emitting element and the light-receiving element of the outlet-side medium detection sensor 85 and is detected by the outlet-side medium detection sensor 85, the control portion 26 rotates the inlet-side conveying rollers 71 and the rear-side conveying rollers 74 in the forward direction by a predetermined amount from that point onward and then stops them. Then, as shown in Figure 5, the leading end of the binding medium T passes between the band fixing member 141 in a standby state and the upstream adjustment plate 125 of the pair of adjustment plates 125 of the chuck portion 91 in the forward feed direction of the binding medium T and the cover portion 112, exceeds the range of lifting and lowering movement of the heater main body portion 161, and stops at a predetermined position upstream of the band detection member 128 in the forward feed direction of the binding medium T.

[0085] Here, when the inlet-side conveying rollers 71 and the inlet-side clamping rollers 72 feed the binding medium T, which is in a standby state as shown in FIG. 4, forward to the bundling unit 63 as shown in FIG. 5, the control unit 26 controls the printer 62 to print a predetermined first inscription X1, as shown in FIG. 6, on the binding medium T at a timing when the binding medium T is fed a predetermined distance from the start of feeding. The predetermined first inscription X1 is written on the binding medium T in a predetermined first printing range from a predetermined printing start position to a predetermined printing end position. In this manner, the printer 62 writes the first inscription X1 on the binding medium T by feeding the binding medium T while the supply unit 61 is supplying the binding medium T. In the example shown in FIG. 6, the first inscription X1 includes the date (year, month, day) and time of bundle creation and a bundle identification number. The control unit 26 sets this predetermined first printing range based on the printing time calculated from the content of the first inscription X1 and the feed speed of the inlet-side conveying rollers 71 and the inlet-side clamping rollers 72. The control unit 26 sets this predetermined first printing range so that when the binding medium T becomes a bundle of paper sheets, the first inscription X1 is placed on the surface of the binding medium T opposite the adhesive portion described below in the stacking direction of the stacked paper sheets SS.

[0086] When the tip of the binding medium T is stopped at a predetermined position beyond the lifting and lowering range of the heater main body 161 as described above, the control unit 26 drives the band fixing drive mechanism of the band fixing part 94 of the binding part 63 to raise the band fixing member 141 as shown in Figure 7, and clamps the tip side of the binding medium T between the upper end of the band fixing member 141 and the adjustment plate 125 upstream in the forward feed direction of the binding medium T.

[0087] In this state, the control unit 26 causes a feeding mechanism (not shown) to transfer the stacked paper sheets SS forward by a predetermined amount, i.e., to the bundling mechanism 52. Then, the stacked paper sheets SS are placed between the pressing unit 92 and the chuck unit 91, which are in a standby state.

[0088] Next, the control unit 26 drives a pressing drive mechanism (not shown) of the pressing unit 92 to lower the pair of pressing pieces 131. Then, as shown in Fig. 8, the pair of pressing pieces 131, together with the pair of inclined support parts 121 of the chuck base part 111, deform the stacked paper sheets SS into a mirror-symmetrical, approximately inverted V-shape in which the left side of the center in the left-right direction is downward sloping to the left and the right side of this center is downward sloping to the right, and clamp the stacked paper sheets SS.

[0089] Next, the control unit 26 causes the pair of arc-shaped inner guides 81 and upper inner guides 82 shown in FIG. 7 to retract rearward by an inner guide drive mechanism (not shown). Thereafter, the control unit 26 drives a supply drive mechanism (not shown) of the supply unit 61 to reversely rotate the inlet-side conveying rollers 71 and the rear-side conveying rollers 74 by a predetermined amount, thereby reversely feeding, i.e., pulling back, the binding medium T being fed out. Then, as shown in FIG. 8, the binding medium T, the leading end of which is sandwiched and fixed between the band fixing member 141 and the cover unit 112, passes through the passage hole 142 of the band fixing member 141 and is returned to the roll-shaped holding unit 70. As shown in FIG. 9, the left and right ends of the stacked paper sheets SS and the portions above them are wrapped around and fastened by the pair of adjustment plates 125 of the chuck unit 91 and the underside of the cover unit 112. As a result, the upper part of the binding medium T wrapped around the stacked paper sheets SS takes on a mirror-symmetrical, approximately inverted V-shape, with the left side sloping downward to the left from the center in the left-right direction and the right side sloping downward to the right from this center.

[0090] Next, the control unit 26 drives a band presser drive mechanism (not shown) of the band presser unit 96 to rotate the band presser member 151 around the support shaft 153, thereby raising the end of the presser member body 152 on the band fixing member 141 side, as shown in FIG. 10. This end of the presser member body 152 then clamps and fixes the tip portion of the binding medium T located below the underside of the cover portion 112 and the middle portion located below this end, between the underside of the cover portion 112. In this state, the band detection member 128 of the band detection mechanism 103 is pushed up by the binding medium T, and this is detected by a band detection sensor (not shown). The control unit 26 then determines that the binding medium T has been properly fastened. Note that even if the control unit 26 drives the band presser drive mechanism (not shown) to rotate the band presser member 151 of the band presser unit 96 as described above, if the band detection mechanism 103 does not detect the binding medium T, the control unit 26 determines that an error has occurred in the bundling process, such as improper winding of the binding medium T. Furthermore, even if the band detection mechanism 103 subsequently stops detecting the binding medium T before the stacked paper sheets SS are pushed out by the delivery mechanism in the bundle release process, as will be described later, the control unit 26 determines that an error has occurred in the bundling process, such as the binding medium T coming loose.

[0091] Next, the control unit 26 drives a cutter drive mechanism (not shown) of the cutter unit 95 to raise the cutter 145 relative to the band fixing member 141, as shown in Fig. 11, and cuts the middle portion of the binding medium T located near the left side of the passage hole 142 of the band fixing member 141. Even after being cut in this manner, the binding medium T wrapped around the stacked paper sheets SS does not loosen because the trailing end portion, which is the side cut by the cutter 145, and the leading end portion on the opposite side are clamped and fixed between the presser member main body 152 and the cover unit 112.

[0092] Next, the control unit 26 drives a cutter drive mechanism (not shown) of the cutter unit 95 to lower the cutter 145 and return it to a standby state, and drives a band fixation drive mechanism (not shown) of the band fixation unit 94 to lower the band fixing member 141 and return it to a standby state. At almost the same time, the control unit 26 drives a heater lift drive mechanism (not shown) of the heater unit 97 to lift the heater main body 161 to the bonding position, as shown in FIG. 12. The heater main body 161 then clamps, between the underside of the cover unit 112, the trailing end portion of the portion of the binding medium T wrapped around the stacked paper sheets SS, which extends to the right of the presser member main body 152, and the leading end portion opposite the trailing end portion. As a result, the heat of the heater main body 161 thermally bonds the trailing end portion and the leading end portion of the binding medium T.

[0093] Next, the control unit 26 causes the entrance-side conveying rollers 71 and the rear-side conveying rollers 74 to rotate in the reverse direction using a supply drive mechanism (not shown) of the supply unit 61, thereby feeding the binding medium T back, i.e., pulling it back, toward the roll-shaped holding unit 70. At this time, the control unit 26 reverses the entrance-side conveying rollers 71 and the rear-side conveying rollers 74 by a predetermined amount from the point when the intermediate medium detection sensor 77 detects the leading edge of the binding medium T, and then stops them. The leading edge of the binding medium T then enters a standby state in which it is positioned closer to the rear-side conveying rollers 74 and rear-side clamping rollers 75 than the printer 62 in the intermediate guide unit (not shown), i.e., at a predetermined lower position.

[0094] Next, the control unit 26 drives a heater lifting / lowering driving mechanism (not shown) of the heater unit 97 to lower the heater main body 161 and return it to the standby state.

[0095] Next, the control unit 26 drives a band presser drive mechanism (not shown) of the band presser unit 96 to rotate the band presser member 151, lowering the end of the presser member body 152 on the band fixing member 141 side and returning it to a standby state. As a result, as shown in Fig. 13, the binding medium T is wound around the stacked paper sheets SS and the pair of adjustment plates 125 and cover unit 112 of the chuck unit 91, and the trailing end portion and the leading end portion are fixed.

[0096] Next, the control unit 26 drives the pressure drive mechanism 273 (not shown) of the pressing unit 92 to raise the pair of pressing pieces 131 and return them to the standby state. At the same time, the control unit 26 narrows the gap between the pair of adjustment plates 125 of the chuck unit 91. Furthermore, the control unit 26 advances the pair of arc-shaped inner guide units 81 and the upper inner guide unit 82 to return them to the standby state. Note that even in this state, as shown in FIG. 13 , the stacked paper sheets SS are pressed against the upper surfaces of the pair of inclined support units 121 of the chuck base unit 111 by the tension of the binding medium T, and are maintained in a mirror-symmetrical, approximately inverted V-shape, with the left side of the center in the left-right direction sloping downward to the left and the right side of this center sloping downward to the right.

[0097] Next, a flux release process is carried out. That is, the control unit 26 causes a not-shown feeding mechanism to push the stacked paper sheets SS forward by a predetermined amount, whereupon the stacked paper sheets SS advance together with the binding medium T due to frictional force caused by the tension of the wrapped binding medium T, and the binding medium T is released forward from the chuck unit 91.

[0098] In this way, when the stacked paper sheets SS and the binding medium T move forward together and the binding medium T is released forward from the chuck portion 91, the stacked paper sheets SS, which had been pressed against the upper surfaces of the pair of inclined support portions 121 of the chuck base portion 111 by the binding medium T and formed into a mirror-symmetric, approximately inverted V-shape, returns to a flat state. In this way, a bundled paper sheet is produced in which the stacked paper sheets SS are bound with the binding medium T. In the bundled paper sheets, the binding medium T has the above-mentioned first inscription X1 written on the upper surface opposite to the adhesive portion in the stacking direction of the stacked paper sheets SS.

[0099] In the bundle discharge process, the control unit 26 causes the bundled paper sheets pushed out by the feeding mechanism (not shown) to be pulled further forward by the discharge mechanism (not shown) and discharged outside the paper sheet bundling device 4 from the bundle dispensing port 55.

[0100] Here, the control unit 26 monitors errors that occur during the bundling process using sensors in each unit, and when an error occurs during the bundling process, performs the following control depending on the operating conditions at that time. This control includes controlling the printer 62 to write a second mark X2 on the bundling medium T downstream of the first mark X1 in the reverse feed direction, indicating that the portion including the location where the first mark X1 was made should be removed. The control unit 26 determines that an error has occurred in the bundling process, for example, when the entrance-side conveying roller 71 and the rear-side conveying roller 74 are rotated forward, and the leading edge of the bundling medium T, which was in a waiting state, is not detected by the intermediate medium detection sensor 77 even when it should be detected by the intermediate medium detection sensor 77; when the entrance-side conveying roller 71 and the rear-side conveying roller 74 are rotated forward, and the leading edge of the bundling medium T is detected by the intermediate medium detection sensor 77, and then the leading edge is detected by the exit-side media detection sensor 85 even when it should be detected by the exit-side media detection sensor 85; when the band detection mechanism 103 does not detect the bundling medium T even when the band pressure drive mechanism (not shown) is driven to rotate the band pressure member 151 of the band pressure unit 96; or when the band detection mechanism 103 detects the bundling medium T, but then stops detecting the bundling medium T before pushing out the stacked paper sheets SS in the bundle discharge process.

[0101] {A first state in which the first marking X1 is printed on the binding medium T by the printer 62, but before the band fixing member 141 clamps and fixes the binding medium T between the adjustment plate 125, and the entire second printing range of the second marking X2 is downstream of the printer 62 in the forward feed direction.}

[0102] In the bundling process, after the first inscription X1 is printed on the bundling medium T by the printer 62, but before the band fixing member 141 clamps and fixes the bundling medium T with the adjustment plate 125, and the entire second printing range of the second inscription X2 (no printing is done at this point) calculated from the amount of rotation from the start of driving the entrance side conveying roller 71 by the supply drive mechanism not shown, is downstream of the printer 62 in the forward feed direction, if an error occurs in the bundling process, the control unit 26 will immediately reverse the rotation of the entrance side conveying roller 71 and the rear side conveying roller 74 by the supply drive mechanism not shown of the supply unit 61, thereby feeding the bundling medium T backward, i.e., pulling it back, toward the roll-shaped holding unit 70.

[0103] During this retraction, the control unit 26 causes the printer 62 to print a predetermined second marking X2 indicating that the portion including the location where the first marking X1 was made should be removed in a predetermined second printing range on the binding medium T downstream in the retraction direction from the first printing range of the first marking X1 determined as described above, as shown in FIG. 14 . This second marking X2 is calculated from the amount of rotation of the entrance-side conveying roller 71 and the rear-side conveying roller 74 by a supply drive mechanism (not shown). In other words, when an error occurs in the bundling process, the printer 62 writes the second marking X2 on the binding medium T downstream in the reverse feed direction from the first marking X1, indicating that the portion including the location where the first marking X1 was made should be removed. In this way, the printer 62 uses the feed of the supply unit 61 to write the second marking X2 on the binding medium T while the binding medium T is being retracted.

[0104] The second description X2 includes a "Tape Cut" instruction X2a indicating that the portion including the location where the first description X1 was made will be removed, a cutting position description X2b of "|" indicating the cutting position of the binding medium T, and a guidance description X2c of "<-" providing guidance to the cutting position description X2b. The guidance description X2c of "<-" is located downstream of the "Tape Cut" instruction X2a in the retraction direction of the binding medium T, and the cutting position description X2b of "|" is located downstream of the guidance description X2c of "<-". The cutting position description X2b of "|" indicating the cutting position is located at the end of the second description X2 downstream in the retraction direction of the binding medium T. Note that the content of the second description X2 here is merely an example, and the content of the description indicating that the portion including the location where the first description X1 was made will be removed is not limited to this content.

[0105] That is, the control unit 26 sets the predetermined second printing range on the binding medium T so that it does not overlap with the first printing range but is downstream of the first printing range in the retraction direction, based on the first printing range, the printing time calculated from the content of the second inscription X2, and the feed speed of the entrance-side conveying rollers 71 and the rear-side conveying rollers 74. Then, while feeding the binding medium T by reverse rotation of the entrance-side conveying rollers 71 and the rear-side conveying rollers 74, the control unit 26 starts printing by the printer 62 when the predetermined second printing range begins to pass the position of the printer 62, and causes the second inscription X2 to be printed in the second printing range on the binding medium T.

[0106] Then, the control unit 26 causes the supply drive mechanism (not shown) to reversely rotate the entrance-side conveying rollers 71 and the rear-side conveying rollers 74 by a predetermined amount required for the leading edge of the binding medium T to separate from the entrance-side conveying rollers 71 and the entrance-side clamping rollers 72 toward the roll-shaped holding unit 70, and then stops the entrance-side conveying rollers 71 and the rear-side conveying rollers 74. When the leading edge of the binding medium T separates from the entrance-side conveying rollers 71 and the entrance-side clamping rollers 72 toward the roll-shaped holding unit 70, the binding medium T stops as no driving force is applied to it.

[0107] Then, the control unit 26 displays the occurrence of an error on the operation display unit 25. In this state, if the operator presses the help button on the operation display unit 25, the control unit 26 displays an explanation of the error content on the operation display unit 25.

[0108] When the operation display unit 25 displays that an error has occurred, the operator performs the error resolution procedure. To do so, the operator opens the front cover (not shown) of the paper sheet bundling device 4 and pulls out the unit 57, including the bundling mechanism 52 and the release mechanism (not shown), from the device main body 58 forward as shown in FIG. 15 . Then, in the unit 57 pulled out from the device main body 58, the leading end of the bundling medium T, whose leading end has moved away from the inlet-side conveying rollers 71 and the inlet-side clamping rollers 72 toward the roll-shaped holding unit 70, is exposed upward. A first notation X1 is written on the top surface of the leading end of the bundling medium T, and a second notation X2 is written closer to the roll-shaped holding unit 70 than the first notation X1. The operator cuts the bundling medium T at the cutting position indicated by the "|" notation X2b in FIG. 14 , which indicates the cutting position of the bundling medium T at the second notation X2. As a result, the portion of the binding medium T that was previously at the tip end and on which the first writing X1 and the second writing X2 are written is separated and removed from the portion on the roll-shaped portion RT side that continues from the roll-shaped holding portion 70.

[0109] The operator then resets the binding medium T. That is, the operator passes the newly formed leading end of the roll-shaped binding medium T held in the roll-shaped holding unit 70 between the light-emitting element and the light-receiving element of the entrance-side medium detection sensor 76 as shown in FIG. 3, and then inserts it between the entrance-side conveying roller 71 and the entrance-side clamping roller 72, and presses the band feed switch 171. This causes the control unit 26 to rotate the entrance-side conveying roller 71 and the rear-side conveying roller 74 in the forward direction using a supply drive mechanism (not shown). As a result, the binding medium T is fed by the entrance-side conveying roller 71 and the entrance-side clamping roller 72, and then by the rear-side conveying roller 74 and the rear-side clamping roller 75.

[0110] When the intermediate medium detection sensor 77 detects the leading edge of the bundling medium T, the control unit 26 causes the inlet-side conveying rollers 71 and the rear-side conveying rollers 74 to rotate in the reverse direction by a predetermined amount using a supply drive mechanism (not shown), thereby feeding the bundling medium T back toward the roll-shaped holding unit 70, i.e., pulling it back. The control unit 26 then reverses the inlet-side conveying rollers 71 and the rear-side conveying rollers 74 by the predetermined amount and stops them. As a result, the bundling medium T enters a standby state in which its leading edge is located on the rear-side conveying roller 74 and rear-side clamping roller 75 side of the printer 62 in the intermediate guide unit (not shown), i.e., below it, as shown in FIG.

[0111] {A second state in which, after the printer 62 starts printing the first marking on the bound medium T, the entire second printing range of the second marking X2 is not located downstream of the printer 62 in the forward feed direction.}

[0112] During the bundling process, after the printer 62 starts printing the first inscription on the bundling medium T, if an error occurs in the bundling process in a second state in which the entire second printing range of the second inscription X2 (not printed) is not located downstream of the printer 62 in the feed direction of the bundling medium T (including a state in which part of it is located), the control unit 26 causes the entrance side conveying roller 71 and the rear side conveying roller 74 to rotate forward using a supply drive mechanism not shown until the entire second printing range of the second inscription X2 (not printed) calculated from the amount of rotation from the start of drive of the entrance side conveying roller 71 by a supply drive mechanism not shown is located at a predetermined position downstream of the printer 62 in the feed direction. Thereafter, the control unit 26 causes the supply drive mechanism (not shown) of the supply unit 61 to reversely rotate the entrance-side conveying rollers 71 and the rear-side conveying rollers 74 by a predetermined amount required for the leading edge of the binding medium T to separate from the entrance-side conveying rollers 71 and the entrance-side clamping rollers 72 toward the roll-shaped holding unit 70, and after this reverse rotation begins, the control unit 26 performs control similar to that in the first state. As a result, the control unit 26 causes the printer 62 to print a predetermined second description X2 indicating that the portion including the location where the first description X1 was made should be removed in a predetermined second printing range downstream in the pullback direction of the first printing range of the first description X1 determined as described above on the binding medium T.

[0113] {A third state from when the band fixing member 141 clamps and fixes the leading end of the binding medium T between the adjustment plate 125 and the heater main body 161 to when the trailing end portion and leading end portion of the binding medium T after cutting are thermally bonded together.}

[0114] In the bundling process, if an error occurs in the third state after the first description X1 is printed on the bundling medium T by the printer 62 and the bundling medium T is clamped and fixed between the band fixing member 141 and the adjustment plate 125, and before the heater main body 161 thermally bonds the rear end portion and the front end portion of the bundling medium T, the control unit 26 will control the bundling process in the same manner as normal until the heater main body 161 thermally bonds the rear end portion and the front end portion of the bundling medium T after cutting.

[0115] The control unit 26 then causes the entrance side conveying roller 71 and the rear side conveying roller 74 to rotate in the reverse direction, and when the intermediate medium detection sensor 77 detects the leading edge of the binding medium T, the control unit 26 rotates the entrance side conveying roller 71 and the rear side conveying roller 74 a predetermined amount required for the leading edge to separate from the entrance side conveying roller 71 and the entrance side clamping roller 72 toward the roll-shaped holding unit 70, and then stops them.

[0116] Then, the control unit 26 displays the occurrence of an error on the operation display unit 25. In this state, if the operator presses the help button on the operation display unit 25, the control unit 26 displays an explanation of the error content on the operation display unit 25.

[0117] When the operation display unit 25 displays that an error has occurred, the operator performs the error resolution procedure. To do so, the operator opens the front cover (not shown) of the paper sheet bundling device 4, pulls out the unit 57 including the bundling mechanism 52 from the device main body 58, and checks the condition of the leading edge of the bundling medium T. If the leading edge of the bundling medium T is creased or damaged, the operator removes the creased or damaged portion of the bundling medium T by cutting it off. The operator then resets the bundling medium T and presses the band feed switch 171. The control unit 26 then rotates the entrance-side conveying roller 71 and the rear-side conveying roller 74 in the forward direction using a supply drive mechanism not shown, and then, when the leading edge of the binding medium T is detected by the intermediate medium detection sensor 77, rotates the entrance-side conveying roller 71 and the rear-side conveying roller 74 in the reverse direction by a predetermined amount using a supply drive mechanism not shown, putting the binding medium T into a standby state in which its leading edge is positioned at a predetermined position on the rear-side conveying roller 74 and rear clamping roller 75 side of the printer 62 in the intermediate guide unit not shown.

[0118] {Fourth state in which the binding medium T is in standby state}

[0119] In the bundling process, if an error occurs in the bundling process in the fourth state where the bundling medium T is in a standby state, the control unit 26 leaves the supply unit 61 as it is.

[0120] {The fifth state after the binding medium T has been fed forward from the standby state and before the printer 62 starts printing the first inscription X1}

[0121] During the bundling process, if an error occurs in the bundling process in the fifth state before the printer 62 starts printing the first description X1 on the binding medium T after the entrance side conveying roller 71 and the rear side conveying roller 74 are rotated forward by the supply drive mechanism (not shown) of the supply unit 61, the control unit 26 rotates the entrance side conveying roller 71 and the rear side conveying roller 74 in the reverse direction a predetermined amount equal to the amount of rotation from the start of the forward rotation of the entrance side conveying roller 71 and the rear side conveying roller 74 by the supply drive mechanism (not shown) of the supply unit 61, and stops them, thereby returning the binding medium T to a standby state in which its leading end is located at a predetermined position on the rear side conveying roller 74 and rear side clamping roller 75 side of the printer 62 in the intermediate guide unit (not shown).

[0122] In the above, in the first state, after the first description X1 is printed on the binding medium T by the printer 62, the control described in the first state is performed before the band fixing member 141 clamps and fixes the binding medium T with the adjustment plate 125, and the entire second printing range of the second description X2 is downstream of the printer 62 in the forward feed direction, but this is not limited to this. For example, after the first description X1 is printed on the binding medium T by the printer 62, before the heater main body 161 thermally bonds the rear end portion and the front end portion of the binding medium T after cutting, and the entire second printing range of the second description X2 is downstream of the printer 62 in the forward feed direction, if the binding medium T is fixed by the band fixing member 141 and the adjustment plate 125, the fixation of the binding medium T by the band fixing member 141 and the adjustment plate 125 can be released, and then, if the binding medium T is not fixed by the band fixing member 141 and the adjustment plate 125, the control described for the first state can be performed as is.

[0123] That is, if an error occurs after the printer 62 prints the first marking X1 on the binding medium T and before the heater main body 161 thermally bonds the trailing end portion and leading end portion of the binding medium T after cutting, and the entire second printing range of the second marking X2 is downstream of the printer 62 in the forward feed direction, the control unit 26 immediately causes the supply drive mechanism (not shown) of the supply unit 61 to reversely rotate the entrance-side conveying rollers 71 and the rear-side conveying rollers 74 by a predetermined amount required for the leading end of the binding medium T to separate from the entrance-side conveying rollers 71 and the entrance-side clamping rollers 72, thereby feeding the binding medium T back toward the roll-shaped holding unit 70, i.e., pulling it back. During this pulling back, the control unit 26 causes the printer 62 to print a predetermined second marking X2, indicating that the portion including the location where the first marking X1 was made, in a predetermined second printing range downstream of the first printing range of the first marking X1 in the pull-back direction.

[0124] As described above, in the paper sheet processing apparatus 1 of this embodiment, the printer 62 prints the first marking X1 on the binding medium T supplied by the supply unit 61. However, when an error occurs, the printer 62 prints the second marking X2 on the binding medium T, indicating that the portion including the location where the first marking X1 was made should be removed. In other words, the control method of the paper sheet processing apparatus 1 of this embodiment causes the printer 62 to print the second marking X2 on the binding medium T, indicating that the portion including the location where the first marking X1 was made should be removed, when an error occurs. This urges the operator to remove the portion of the binding medium T where the marking is made. Therefore, when the error is recovered, the operator can easily remove the portion of the binding medium T where the marking is made. Therefore, after the error is recovered, it is possible to prevent double marking on the binding medium T and to prevent misidentification or difficult-to-read information from being written on the binding medium T. As a result, it is possible to prevent management problems that may arise with the bundled paper sheets, which may require recounting, and it is also possible to prevent the hassle of unravelling the bundling medium T and bundling it again.

[0125] Furthermore, in the paper sheet processing apparatus 1, when an error occurs, the supply unit 61 retracts the bound medium T. However, the printer 62 writes the second marking X2 downstream of the first marking X1 on the bound medium T in the retraction direction by the supply unit 61, i.e., toward the roll-shaped holding unit 70, which is the supply source. This allows the operator to clearly see the second marking X2. Furthermore, if the operator cuts the bound medium T to remove the second marking X2, the first marking X1 will also be removed. Therefore, during error recovery, the operator can more clearly remove the portion of the bound medium T where the first marking X1 and the second marking X2 are present. Therefore, after error recovery, double marking on the bound medium T can be further prevented, and misidentification or difficulty in reading the markings on the bound medium T can be further prevented.

[0126] Furthermore, in the paper sheet processing apparatus 1, the second marking X2, which is written downstream of the first marking X1 on the binding medium T in the retraction direction by the supply unit 61, i.e., on the supply source side, has a cutting position marking X2b (|) indicating the cutting position at the downstream end of the binding medium T in the retraction direction by the supply unit 61, i.e., the end on the supply source side. Therefore, if the operator cuts the binding medium T at the cutting position marking X2b, the first marking X1 and the second marking X2 on the binding medium T can be reliably removed. Therefore, during error recovery, the operator can more effectively remove the portions of the binding medium T where the first marking X1 and the second marking X2 are located. Therefore, after error recovery, double marking on the binding medium T can be more effectively prevented, and misidentification or difficult-to-read information on the binding medium T can be more effectively prevented. Furthermore, removing portions of the binding medium T that do not need to be removed can be prevented, thereby saving the binding medium T.

[0127] In addition, in the paper sheet processing device 1, the printer 62 writes the first inscription X1 on the binding medium T while the supply unit 61 is supplying the binding medium T, and when an error occurs, writes the second inscription X2 on the binding medium T while the supply unit 61 is retracting the binding medium T, thereby shortening the time required to write the second inscription X2 downstream in the retraction direction of the first inscription X1.

[0128] Furthermore, the sheet processing apparatus 1 can write the first inscription X1 and the second inscription X2 by printing using a single printer 62. This reduces costs. It is also possible to write the first inscription X1 on the bound medium T by printing using one printer (first inscription unit) and write the second inscription X2 on the bound medium T by printing using a different printer (second inscription unit). In this case, for example, it is possible to arrange another printer downstream in the reverse feed direction from the first printer. With this arrangement, even if an error occurs in a second state where the entire second printing range of the second inscription X2 is not downstream in the forward feed direction from the first printer after the first printer starts printing the first inscription on the bound medium T, the inlet-side conveying rollers 71 and the rear-side conveying rollers 74 can be immediately rotated in the reverse direction by a supply drive mechanism (not shown) of the supply unit 61, thereby controlling the other printer to print the second inscription, thereby reducing processing time.

[0129] [Variations] While the above description has been given using a dot matrix printer as the printer 62, an inkjet printer can also be used. If an inkjet printer is used as the printer 62, the first description Y1 can be written in more detail, for example, as a two-dimensional code description Y1a containing information such as the date, time, and bundle identification number, or as a character string description Y1b containing information such as the date, time, and bundle identification number arranged in multiple rows in the width direction of the binding medium T, as shown in FIG. 16. Furthermore, the second description Y2 can be written in more detail, for example, as an instruction description Y2a indicating the removal of the portion including the location where the first description Y1 was made, combining an illustration arranged in the width direction of the binding medium T with the words "Please Tape Cut." Alternatively, the cutting position description Y2b indicating the cutting position of the binding medium T can be written as multiple "|"s arranged in a row in the width direction of the binding medium T, or as a guide description Y2c providing guidance to the cutting position description Y2b, as an arrow.

[0130] In the above, an example has been described in which the first notation X1 and the second notation X2 are written on the binding medium T by the printer 62, but the first notation X1 may be written by impressing with a stamp mechanism, and the second notation X2 may be written by impressing with a stamp mechanism. For example, if the first notation X1 includes a variable date, time, bundle identification number, etc., the first notation X1 may be printed by the printer 62, and the second notation X2, which will always be the same and includes instructions to remove the portion including the location where the first notation X1 was made, may be impressing with a stamp mechanism.
