Summary of the Invention

Problems to be Solved by the Invention

[0004] The input unit of such a paper sheet processing apparatus has a placement unit on which paper sheets are placed in an aggregated state, and a back plate unit that faces one edge portion of the paper sheets placed on the placement unit. When a user sets paper sheets in the input unit, one edge portion of the paper sheets is abutted against the back plate unit and set on the placement unit or on the paper sheets already placed on the placement unit. By the way, when adding additional paper sheets on the paper sheets already placed on the placement unit, the uppermost paper sheet among the already placed paper sheets may be pushed toward the back plate unit side by the additional paper sheets. Then, this uppermost paper sheet may shift toward the back plate unit side, and a part on the back plate unit side may enter between the additional paper sheets and the back plate unit. If the paper sheets in this state are taken into the apparatus by the intake unit, jams may occur.

[0005] Therefore, an object of the present invention is to provide a paper sheet processing apparatus capable of suppressing the occurrence of jams during the intake of paper sheets into the apparatus.

Means for Solving the Problems

[0006] To achieve the above objective, one aspect of the present invention comprises a mounting section on which sheets of paper are placed in an accumulated state, a back plate section facing one edge of the sheets of paper placed on the mounting section, a bill press provided to be vertically movable along the back plate section and capable of pressing the sheets of paper toward the mounting section, and a take-up section for taking the sheets of paper placed on the mounting section into the device, wherein the back plate section is provided with a napped seal extending vertically toward the sheets of paper and a guide section extending vertically toward the side of the napped seal and protruding more than the napped seal toward the sheets of paper. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a paper sheet processing device that can suppress the occurrence of jams that occur when paper sheets are fed into the device. [Brief explanation of the drawing]

[Figure 7] This is a plan view showing a modified example of the back plate portion of a paper sheet processing device according to one embodiment of the present invention. [Modes for carrying out the invention]

[0009] A paper sheet processing device according to one embodiment of the present invention will be described below with reference to the drawings.

[0010] [Overall configuration of paper sheet processing device 1] As shown in Figure 1, the paper sheet processing device 1 according to this embodiment processes paper sheets S, for example, banknotes, and is composed of a base machine 2 and a connecting unit 3. Here, the paper sheet processing device 1 is composed of selecting and setting at least one of the number and type of connecting units from among a plurality of types, and connecting them to the base machine 2 in an appropriate order. The connecting unit 3 includes those that perform a bundling process to tie the paper sheets into bundles of a predetermined number of sheets, and those that perform a stacking process to classify the paper sheets and accumulate them so that they can be removed from the machine. In the specific example shown in Figure 1, the paper sheet processing device 1 is composed of a base machine 2 connected to a single connecting unit 3 that performs a bundling process. The paper sheet processing device 1 of this specific example will be described below. In the following description, the left side of the paper sheet processing device 1 as viewed from the user side is the left side in the left-right direction of the device, and the right side is the right side in the left-right direction of the device. Also, the user side of the paper sheet processing device 1 is the front in the front-rear direction of the device, and the side opposite the user is the rear in the front-rear direction of the device.

[0011] Base machine 2 identifies and counts paper sheets S inserted from outside the machine by the user. Base machine 2 has an input section 11 at the lower right end of the device in the left-right direction, and a reject section 12 above the input section 11 at the same right end.

[0012] Paper sheets S are fed into the input section 11 from outside the machine by the user. At this time, the paper sheets S are stacked vertically in the input section 11 with their long sides aligned in the front-to-back direction of the device (the direction perpendicular to the paper surface in Figure 1) and their short sides aligned in the left-to-right direction of the device, and placed on the upward-facing loading section 20. The input section 11 then moves the stacked paper sheets S one by one from the bottom so that their short sides are aligned in the transport direction, and feeds them out to the left in the left-to-right direction of the device. Throughout the paper sheet processing device 1, the paper sheets S move while maintaining the orientation with their long sides aligned in the front-to-back direction of the device.

[0013] The base machine 2 has an identification and transport unit 21 that receives and transports paper sheets S fed into and unfed from the input unit 11, and an identification unit 22 that identifies the paper sheets S being transported by the identification and transport unit 21. The identification and transport unit 21 extends horizontally from the input unit 11 to the left in the left-right direction of the device, and then extends upward. The identification unit 22 is provided in this upwardly extending portion of the identification and transport unit 21.

[0014] The input section 11 includes the aforementioned loading section 20 on which the paper sheets S are placed in a stacked state, a back plate section 25 provided along the left edge of the loading section 20 that runs in the front-to-back direction of the device and is positioned perpendicularly upward to the loading section 20 and facing to the right in the left-to-right direction of the device, a bill press 26 provided to be vertically movable along the back plate section 25 and capable of pressing the paper sheets S placed on the loading section 20 toward the loading section 20 from above, and a take-up section 27 provided near the loading section 20 that takes in the paper sheets S placed on the loading section 20 one by one, starting from the bottom. The loading section 20 and the back plate section 25 are planar in shape that extends in the front-to-back direction of the device. The back plate section 25 faces one edge (on the left side in the left-to-right direction of the device) of the paper sheets S placed on the loading section 20.

[0015] The mounting section 20 extends downward to the left in the left-right direction of the device, and therefore the back plate section 25 extends upward to the left in the left-right direction of the device. The user places multiple stacked sheets of paper S into the input section 11, shifting them from the right side in the left-right direction of the device to the left side, and then places them on the mounting section 20. As a result, the multiple stacked sheets of paper S placed on the mounting section 20 have one edge (the long left side in the left-right direction of the device) of each sheet of paper S facing the back plate section 25 abut against the back plate section 25, aligning their positions in the width direction (left-right direction of the device). Note that Figure 1 is a schematic diagram, so the sheets of paper S are shown to be away from the back plate section 25, but in reality they are abutting against it. Even when adding sheets of paper S to a stack of sheets of paper S already placed on the mounting section 20, the user places the additional sheets of paper S on top of the stack of sheets of paper S already placed on the mounting section 20, shifting them to the left side in the left-right direction of the device. Thus, the additional sheets of paper S are also aligned in the width direction, with one edge (the long left side in the left-right direction of the device) abutting against the back plate section 25.

[0016] The intake unit 27 has an intake port 31 between the lower end of the back plate unit 25 and the placement unit 20. The intake unit 27 is provided on the placement unit 20 and includes a kick-out roller 32 that kicks out the lowermost sheet S in the stack of sheets S placed on the placement unit 20 toward the intake port 31, and an intake roller 33 and a separation roller 34 that are provided near the intake port 31, separate the sheets S kicked out by the kick-out roller 32 one by one, take them in, and deliver them to the identification and conveyance unit 21.

[0017] As described above, the input unit 11 has a building press 26 that is movable in the vertical direction along the back plate unit 25. When the amount of the sheets S stacked on the placement unit 20 becomes less than a predetermined amount, the building press 26 presses the sheets S from above to below, that is, toward the placement unit 20, with a force corresponding to the amount. As a result, in the input unit 11, the lowermost sheet S among the sheets S stacked on the placement unit 20 adheres to the kick-out roller 32 and is kicked out well.

[0018] The upper end portion above the identification unit 22 of the identification and conveyance unit 21 branches and extends to the left and right in the device left-right direction. The identification and conveyance unit 21 conveys the sheets S that were not identified as objects to be processed by the connection unit 3 in the identification unit 22 to the reject unit 12 through the portion that extends to the right in the device left-right direction at the upper end. The identification and conveyance unit 21 conveys the sheets S that were identified as objects to be processed by the connection unit 3 in the identification unit 22 from the base machine 2 toward the connection unit 3 through the portion that extends to the left in the device left-right direction at the upper end.

[0019] The base machine 2 has a motion sensor (not shown) that detects the movement of the user at the right end in the device left-right direction on the front side in the device front-back direction of the input unit 11. The base machine 2 has a control unit 35. The control unit 35 controls the entire base machine 2 and is also communicably connected to the connection unit 3 via an interface to output a control command.

[0020] The connecting unit 3 receives the paper sheets S that have been transported by the identification transport unit 21 of the base machine 2, collects them in predetermined numbers (for example, 100 sheets), and performs a bundling process by wrapping them with bundling tape. The connecting unit 3 has a connecting transport unit 43 that receives the paper sheets S from the identification transport unit 21 of the base machine 2 and transports them to the bundling unit 42 where the bundling process of the paper sheets S is performed.

[0021] The bundling unit 42 has an alignment and stacking unit 44 and an alignment and stacking unit 45 at the end of the connecting and conveying unit 43. The alignment and stacking units 44 and 45 each receive the paper sheets S fed out from the connecting and conveying unit 43, align them to a predetermined number of bundling units, and stack them. The bundling unit 42 has a downward conveying unit 46 that conveys the stacked paper sheets S that have been fed out to the right in the left-right direction of the device from the alignment and stacking units 44 and 45. The bundling unit 42 also has a bundling mechanism unit 47 that bundles the stacked paper sheets S conveyed by the downward conveying unit 46 with bundling tape and integrates them into a bundle of paper sheets. Furthermore, the bundling unit 42 has an external discharge unit 48 that discharges the bundle of paper sheets created by the bundling mechanism unit 47 to the outside of the machine. The connecting unit 3 is equipped with a control unit 49 inside that receives control commands from the control unit 35 of the base unit 2 and controls the connecting unit 3.

[0022] The paper sheet processing device 1 takes in the paper sheets S that are stacked on the loading section 20 of the input section 11, separates them one by one using the intake section 27, and takes them into the device. The identification and transport section 21 transports the taken-in paper sheets S using the base machine transport process, and the identification section 22 performs an identification and counting process that identifies and counts the paper sheets S. The paper sheet processing device 1 transports the paper sheets S identified as tickets to be bundled by the identification section 22 from the base machine 2 to the connecting unit 3 using the base machine transport process of the identification and transport section 21, and transports the paper sheets S that were not identified as tickets to be bundled by the identification section 22 to the reject section 12 using the identification and transport section 21. Then, the connecting transport section 43 of the connecting unit 3 transports the paper sheets S identified as tickets to be bundled to the bundling section 42 using the unit transport process, and the bundling section 42 performs the bundling process of the paper sheets S identified as tickets to be bundled. The processes of taking in the materials, transporting them within the base machine, identifying them, transporting them within the unit, and bundling them together constitute the identification, counting, and bundling process.

[0023] In this identification, counting, and bundling process, if a sensor (not shown) detects that the amount of paper sheets S placed on the loading section 20 of the input section 11 is less than a predetermined amount, or has become less than a predetermined amount, the control unit 35 lowers the bill press 26 towards the loading section 20 to press the paper sheets S against the kick roller 32 of the intake section 27. If the user adds more paper sheets S to the input section 11 during the identification, counting, and bundling process, a motion sensor (not shown) detects such hand movements of the user. In this case, the control unit 35 stops the intake section 27 and raises the bill press 26. In this state, the user places the additional paper sheets S on top of the stacked paper sheets S already placed on the loading section 20 and presses the start switch (not shown). If the amount of paper sheets S placed on the loading section 20 after the addition is less than a predetermined amount, the control unit 35 lowers the bill press 26 to press the paper sheets S against the ejection roller 32 of the intake section 27, and then resumes the intake process by the intake section 27. If the amount of paper sheets S placed on the loading section 20 after the addition is greater than or equal to the predetermined amount, the control unit 35 resumes the intake process by the intake section 27 without lowering the bill press 26. The user repeats the addition of paper sheets S to the input section 11 as needed.

[0024] [Configuration of the input section 11, which is the main part of the embodiment] The loading section 11 has a mounting section 20 that extends in the front-to-back direction of the device and slopes downward to the left in the left-to-right direction of the device, as described above. The loading section 11 also has a back plate section 25 that extends in the front-to-back direction and slopes upward to the left in the left-to-right direction of the device. Multiple sheets of paper S are placed in the loading section 11 with one edge of each sheet of paper S (the long left side in the left-to-right direction of the device) abutting against the back plate section 25, either on the mounting section 20 or on top of sheets of paper S already placed on the mounting section 20.

[0025] As shown in Figure 2, the input section 11 has a pair of guide plates 51 on both sides of its back plate 25 in the front-to-back direction of the device. The pair of guide plates 51 are detachable from the back plate 25 and, when attached to the back plate 25, spread out perpendicular to the front-to-back direction of the device. Each of the pair of guide plates 51 is adjustable in the front-to-back direction of the device and is positioned according to the length of the long side of the paper sheets S to be processed. When the stacked paper sheets S are placed on the loading section 20, the front end in the front-to-back direction of the device is positioned by the front guide plate 51 in the front-to-back direction of the device, and the rear end in the front-to-back direction of the device is positioned by the rear guide plate 51 in the front-to-back direction of the device. At this time, the center position (center position in the long side direction) of paper sheets S of any length is fixed in the front-to-back direction of the device. This position is the central reference position of the input section 11. In other words, the pair of guide plates 51 are positioned at equidistant positions from this central reference position.

[0026] As shown in Figures 2 to 4, the back plate portion 25 has a metal back plate body 55 and a pair of synthetic resin napped seals 56 that are attached to the back plate body 55. The pair of napped seals 56 are positioned on the back plate body 55 spaced apart in the front-to-back direction of the device. As shown in Figure 2, the back plate body 55 extends in the front-to-back direction of the device and extends upward to the left in the left-to-right direction of the device, and has a main body 61 to which a pair of guide plate portions 51 are attached in an adjustable position, a pair of guide portions 62 spaced apart in the front-to-back direction of the device, and a pair of guide grooves 63 spaced apart in the front-to-back direction of the device. The pair of guide portions 62 and the pair of guide grooves 63 extend along the vertical direction.

[0027] A pair of guide sections 62, spaced apart in the front-to-back direction of the device, are seamlessly and integrally formed with the main body 61. The pair of guide sections 62 are mirror-symmetrical with respect to a central reference position. One of the pair of guide sections 62 (the rear side in the front-to-back direction of the device) is formed closer to the central reference position than one of the pair of guide plate sections 51 (the rear side in the front-to-back direction of the device). The other of the pair of guide sections 62 (the front side in the front-to-back direction of the device) is formed closer to the central reference position than the other of the pair of guide plate sections 51 (the front side in the front-to-back direction of the device). As shown in Figure 4, the pair of guide sections 62 protrude to the right in the left-to-right direction of the device from the main body 61, i.e., towards the paper sheets S set in the input section 11. The pair of guide sections 62 face the edge of the back plate section 25 side of the paper sheets S set in the input section 11 (the long left side in the left-to-right direction of the device). Each of the pair of guide sections 62 has an extension 67 that extends from the main body 61 to the right in the left-right direction of the device and toward the central reference position, and a guide body 68 that extends parallel to the main body 61 toward the central reference position from the edge of the extension 67 opposite to the main body 61. Both the extension 67 and the guide body 68 extend along the vertical direction. The distance between the opposite ends of the guide body 68 of each of the pair of guide sections 62 is shorter than the length of the paper sheet S with the shortest length in the long side direction among the paper sheets S processed by the paper sheet processing device 1.

[0028] As shown in Figure 2, a pair of guide grooves 63, spaced apart in the front-rear direction of the device, are formed penetrating the main body 61 in the thickness direction. The pair of guide grooves 63 are mirror-symmetrical with respect to a central reference position. One of the pair of guide grooves 63 (the rear side in the front-rear direction of the device) is formed close to the central reference position side of one of the pair of guide parts 62 (the rear side in the front-rear direction of the device). This guide groove 63 is formed by cutting and raising the adjacent guide part 62 from the main body 61. The other of the pair of guide grooves 63 (the front side in the front-rear direction of the device) is formed close to the central reference position side of the other of the pair of guide parts 62 (the front side in the front-rear direction of the device). This guide groove 63 is also formed by cutting and raising the adjacent guide part 62 from the main body 61. On the left side of the back plate section 25 in the left-right direction of the device, there is a lifting drive unit (not shown) for raising and lowering the bill press 26, and the lifting drive unit is connected to the bill press 26 through a pair of guide grooves 63. The bill press 26 is shaped so that the back plate body 55 side is close to the main body section 61 and avoids a pair of guide sections 62, and moves up and down parallel to the main body section 61 along the pair of guide grooves 63 driven by the lifting drive unit (not shown).

[0029] A pair of napped seals 56, spaced apart in the front-to-rear direction of the device, extend along the vertical direction and are attached to the main body 61. The pair of napped seals 56 are mirror-symmetrical with respect to a central reference position. One of the pair of napped seals 56 (the rear side in the front-to-rear direction of the device) is attached to the main body 61, close to the central reference position side of one of the pair of guide grooves 63 (the rear side in the front-to-rear direction of the device). The other of the pair of napped seals 56 (the front side in the front-to-rear direction of the device) is attached to the main body 61, close to the central reference position side of the other of the pair of guide grooves 63 (the front side in the front-to-rear direction of the device). One of the pair of napped seals 56 (the rear side in the front-to-back direction of the device) is located close to the central reference position of one of the pair of guide sections 62 (the rear side in the front-to-back direction of the device), and the other of the pair of napped seals 56 (the front side in the front-to-back direction of the device) is located close to the central reference position of the other of the pair of guide sections 62 (the front side in the front-to-back direction of the device). Here, two napped seals 56 are provided in the input section 11, but three or more may be provided. Therefore, it is possible to provide multiple napped seals 56 in the input section 11, and the guide sections 62 are provided close to both outer sides of these multiple napped seals 56, that is, close to the sides opposite to the central reference position of the entire set of multiple napped seals 56.

[0030] The pair of napped seals 56 protrude from the main body portion 61 of the backing plate body 55 to the right in the left-right direction of the device, that is, towards the paper sheets S that are placed and set on the placement portion 20 in the input portion 11. The pair of napped seals 56 face the edge portion (the long left side in the left-right direction of the device) of the backing plate portion 25 of the paper sheets S that are placed and set on the placement portion 20 in the input portion 11. Each of the pair of napped seals 56 has a strip-shaped seal base portion 71 that is attached to the main body portion 61 of the backing plate body 55, and a number of napped portions 72 that extend downwards from the seal base portion 71 (downwards to the right in the left-right direction of the device). All of the napped portions 72 of the napped seal 56 extend downwards from the seal base portion 71.

[0031] Therefore, the back plate portion 25 is provided with a pair of napped seals 56 extending vertically on the side of the paper sheets S placed on the mounting portion 20, as shown in Figure 3, and guide portions 62 extending vertically on the side opposite to the central reference position of each of the pair of napped seals 56. Furthermore, the height H1 of the pair of guide portions 62 at the end on the side of the paper sheets S placed on the mounting portion 20, i.e., the right end in the left-right direction of the device, from the main body portion 61, is higher than the height H2 of the same end of the pair of napped seals 56, i.e., the right end of the napped portion 72 in the left-right direction of the device, from the main body portion 61, as shown in Figure 5. In other words, the pair of guide portions 62 protrude more than the pair of napped seals 56 towards the side of the paper sheets S placed on the mounting portion 20. Specifically, the height H1 of the end of the pair of guide portions 62 on the side of the paper sheets S placed on the mounting portion 20 is 0.3 mm to 1.0 mm higher than the height H2 of the same end of the pair of napped seals 56. Preferably, the height H1 of the end of the pair of guide portions 62 on the side of the paper sheets S placed on the mounting portion 20 is 0.5 mm higher than the height H2 of the same end of the pair of napped seals 56.

[0032] The user inserts multiple stacked sheets of paper S from the right side in the left-right direction of the device between a pair of guide plate sections 51, and places them on the mounting section 20, shifting them to the left side in the left-right direction of the device. At this time, the stacked sheets of paper S placed on the mounting section 20 are placed with one edge (the long left side in the left-right direction of the device) of each sheet of paper S facing the back plate section 25 abutting against the guide body section 68 of the guide section 62 of the back plate section 25, so that their positions in the width direction (left-right direction of the device) are aligned. When adding sheets of paper S on top of stacked sheets of paper S already placed on the mounting section 20, the user places the additional sheets of paper S on top of the stacked sheets of paper S already placed on the mounting section 20, shifting them to the left side in the left-right direction of the device. Thus, the additional sheets of paper S are also abutted against the guide body section 68 of the guide section 62 of the back plate section 25.

[0033] Incidentally, when a user places additional sheets of paper S on top of a stack of paper S already placed on the placement section 20, shifting them to the left side in the left-right direction of the device, the additional sheets of paper S may push the upper end of the stack of paper S already placed on the placement section 20 towards the back plate section 25. This causes the upper end of the already placed sheets of paper S to shift towards the back plate section 25. However, in the paper sheet processing device 1 of this embodiment, the sheets of paper S that try to shift towards the back plate section 25 will bend and get caught between the pair of guide sections 62, and thus engage with the downward-sloping napped section 72 of the napped seal 56. As a result, the napped section 72 suppresses the upward movement of the sheets of paper S that try to shift, and thus prevents them from getting caught between the additional sheets of paper S and the back plate section 25. Therefore, it is possible to suppress jams that occur when loading paper sheets S, which are caused by paper sheets S that have shifted toward the back plate portion 25 getting stuck between the additional paper sheets S and the back plate portion 25. In addition, the downward-sloping napped portion 72 of the napped seal 56 does not easily engage with the paper sheets S when they are placed on the loading portion 20, so the paper sheets S can be placed on the loading portion 20 smoothly.

[0034] Here, even if the guide portion 62 is not provided, if the napped seal 56 is provided, as described above, even if the upper end of the stacked paper sheets S already placed on the mounting portion 20 is pushed towards the back plate portion 25 by the additional paper sheets S, the napped seal 56 can prevent the pushed paper sheets S from getting stuck between the additional paper sheets S and the back plate portion 25. However, for example, if the build press 26, which had been pressing the stacked paper sheets S towards the mounting portion 20, is raised away from the mounting portion 20 in order to add further paper sheets S, the compression of the stacked paper sheets S that had been compressed until then is released and they expand, and the paper sheets S may engage with the napped seal 56, restricting the upward movement towards the back plate portion 25. As a result, when the stacked paper sheets S on the loading section 20 are stacked, the bulging on the side opposite the backing plate 25 is suppressed, while the side opposite the backing plate 25 bulges. This causes the paper sheets S at the upper end to rise on the side opposite the backing plate 25 and move closer to the backing plate 25. Consequently, it becomes impossible to properly load additional paper sheets S, and the stacked state of the paper sheets S on the loading section 20 needs to be corrected. This problem is particularly likely to occur when a large number of paper sheets S with significant warping are stacked.

[0035] In contrast, the paper sheet processing device 1 of this embodiment is provided with a guide portion 62 that extends vertically to the side of the napped seal 56 and protrudes more than the napped seal 56 on the paper sheet side S. Therefore, as described above, the paper sheet S that is pushed towards the back plate portion 25 by the additional paper sheet S is engaged with the napped portion 72 of the napped seal 56, which is at a height H2 lower than the height H1 of the guide portion 62, by its flexure, thereby preventing it from getting stuck between the additional paper sheet S and the back plate portion 25. Subsequently, when the force pushing towards the back plate portion 25 is released, the flexure of the paper sheet S that was engaged with the napped portion 72 of the napped seal 56 is reduced, and at that time, the position of the paper sheet S is corrected by the guide body portion 68 of the guide portion 62 that protrudes more than the napped seal 56, and it moves away from the napped seal 56 and comes into contact with the guide body portion 68 of the guide portion 62. Therefore, for example, if the build press 26 is raised to move away from the mounting section 20 in order to add more sheets of paper S, the compression of the previously compressed stacked sheets of paper S will be released and they will expand. However, the upward movement of the sheets of paper S on the back plate section 25 side will not be restricted by the napped section 72. As a result, the stacked sheets of paper S will expand similarly on both the side facing the back plate section 25 and the side opposite the back plate section 25. Therefore, additional sheets of paper S can be placed on the build press 26 without any modifications to the stacked state of the sheets of paper S on the mounting section 20.

[0036] Furthermore, in this embodiment, the paper sheet processing device 1 has a napped seal 56 with a napped portion 72 that extends downwards towards the front. Therefore, even if the upper end of the stacked paper sheets S already placed on the mounting section 20 is pushed towards the back plate section 25 by the additional paper sheets, the napped portion 72 of the napped seal 56 that extends downwards towards the front effectively prevents the pushed paper sheets S from getting stuck between the additional paper sheets S and the back plate section 25.

[0037] Furthermore, in this embodiment, since the guide portion 62 of the paper sheet processing device 1 is provided close to both outer sides of the multiple napped seals 56, the position of the paper sheets S that were engaged with the napped seals 56 can be effectively corrected by the guide portion 62.

[0038] Furthermore, the paper sheet processing apparatus 1 of the embodiment described above can be modified as shown in the following modified examples 1 to 3.

[0039] <Example 1> In the above embodiment, the back panel body 55 is provided with a main body portion 61 and a pair of guide portions 62 integrated with the main body portion 61. However, as shown in Figures 6 and 7, the back panel body 55 may be provided with a main body portion 61 and a pair of guide grooves 63, while instead of the pair of guide portions 62, a pair of guide plates 62A (guide portions) separate from the back panel body 55 may be attached to the main body portion 61. The pair of guide plates 62A are strip-shaped and extend in the vertical direction, protruding from the main body portion 61 to the same height H1 as the guide portions 62. The pair of guide plates 62A are also provided with respect to the pair of napped seals 56 and the pair of guide grooves 63 in the same way as the pair of guide portions 62.

[0040] <Modification 2> In the above embodiment, a pair of napped seals 56 are provided on the back plate portion 25. However, a single napped seal similar to the napped seals 56 may be provided in place of the pair of napped seals 56, with a width equal to the distance between the opposite outer ends of the pair of napped seals 56. In this case as well, the pair of guide portions 62 are provided close to both outer sides of the single napped seal. This modified example 2 may be combined with modified example 1 to provide a pair of guide plates 62A close to both outer sides of the single napped seal.

[0041] <Variation 3> In the above embodiment, the guide portion 62 may be configured to elastically reduce the height of the end opposite to the main body portion 61 from the main body portion 61. With this configuration, when the paper sheets S are moved toward the backing plate portion 25, the force causes the guide portion 62 to contract toward the main body portion 61, allowing the paper sheets S to engage well with the napped seal 56. When the force of this movement is released, the guide portion 62 returns to its original position, allowing the paper sheets S to be separated from the napped seal 56.

[0042] Furthermore, the present invention is not limited to the paper sheet processing device 1 of the embodiment, but is applicable to all paper sheet processing devices that take in stacks of paper sheets fed from an external source one by one and process them within the device.
