  Hereinafter, a sheet processing apparatus according to the present invention will be described in detail with reference to the accompanying drawings. Although a paper sheet processing apparatus can make various paper sheets, such as a banknote, a check, a gift certificate, etc. into a process target, the banknote processing apparatus which makes a process target a banknote below is demonstrated to an example. This banknote handling apparatus feeds a plurality of banknotes received at the receiving port one by one to the transport path in the apparatus, and identifies and counts the denomination, authenticity, damage (degree of damage), etc. by the identification unit. After that, the banknotes are classified and stacked according to type in a plurality of stacking units having openings for extracting banknotes from the front side of the apparatus. However, since such banknote processing apparatuses are conventionally used, Description of the structure and operation will be omitted, and the structure of the stacking unit will be described.

  Drawing 1 is a mimetic diagram for explaining the structure in the accumulation part of the bill processing device concerning this embodiment. 1A is a view of the inside of the stacking unit as viewed from above, and FIG. 1B is a view of the stacking portion as viewed from the side. In the drawings shown in the present embodiment, the X-axis positive direction side corresponds to the front side (front) of the banknote processing apparatus, and the X-axis negative direction side corresponds to the back side (rear) of the banknote processing apparatus. From the opening provided on the X axis positive direction side of the stacking unit, the user who uses the banknotes pulls out banknotes in the stacking unit. The Y-axis positive direction side corresponds to the right side when the banknote processing apparatus is viewed from the front side, the Y-axis negative direction side corresponds to the left side, the Z-axis positive direction side corresponds to the upper side of the apparatus, and the Z-axis negative direction side corresponds to the lower side of the apparatus. In the drawing shown in this embodiment, as indicated by an arrow in FIG. 1, the conveyance path in the banknote handling apparatus is conveyed from the Y axis positive direction side and the Z axis upper side, that is, from the upper right as viewed from the front side of the apparatus. An example is shown in which banknotes that have been sent are fed into a stacking unit and stacked.

  As shown in FIG. 1A, a front side stage 20, a back side stage 30, and a pushing member 10 are provided in the stacking unit. In the stacking unit, banknotes are stacked on the front side stage 20 and the back side stage 30 between the stacking unit left side wall 40 and the stacking unit right side wall 41 fixed to the banknote processing apparatus. Hereinafter, the stage formed by the front side stage 20 and the back side stage 30 is simply referred to as a “banknote stage”.

  The shape of the pushing member 10 viewed from above is formed in an inverted L shape in which a left side wall portion on the left side of the device and a back wall portion (back surface portion) on the back side of the device are connected. A long guide groove 10a is formed on the inner side surface (right side surface) of the left side wall portion, and a long guide groove 10b is formed on the inner side surface (front surface) of the rear wall portion in the same manner. The pushing member 10 is restricted in movement in the left-right direction of the back wall between the stacking unit left side wall 40 and the stacking unit right side wall 41, and the stacking unit left side wall 40, the front side stage 20 and the back side stage 30 are The movement of the left side wall in the left-right direction is restricted. On the other hand, a gap is provided between the front side stage 20 and the stacking portion left side wall 40 so that the left side wall portion of the pushing member 10 can move forward, so that the pushing member 10 can slide and move in the front-rear direction. It has become. The pushing member 10 moves together with the back side stage 30, which will be described later.

  The front surface of the back wall portion of the extruding member 10 functions as an extruding surface for extruding the banknote, and when the extruding member 10 moves forward, the back side edge of the banknote accumulated on the banknote stage is pushed by the extruding surface. Moving. The extruded surface has, for example, a shape including a region facing the opening of the stacking unit for extracting banknotes. In other words, the extrusion surface is formed so as to be larger than the opening when viewed from the front side of the apparatus. Specifically, for example, the opening of the accumulation portion is formed to be narrower than the left and right width of the front stage 20 shown in FIG. 1A and lower than the height of the pushing member 10 shown in FIG. The extruded surface is wider and higher than the extruded surface.

  The front side stage 20 has a substantially rectangular thin plate shape, and a part on the front side of the apparatus is cut out in a U-shape so that the bills stacked on the bill stage can be easily grasped from above and below. Further, the front stage 20 is formed with a support portion 20a having a through-hole penetrating vertically at a position on the right outside of the banknote stacking surface. A groove that is long in the vertical direction is formed in the right-hand side wall 41 of the stacking portion so as to correspond to the support portion 20a, and the support portion 20a can move in the vertical direction in this groove. A round bar-shaped slide shaft 42 penetrating the through hole of the support portion 20a is fixed to the banknote processing apparatus, and the front side stage 20 supported by the slide shaft 42 moves in the vertical direction (Z-axis) along the slide shaft 42. Direction).

  A boss 20 b is formed on the back surface of the front stage 20. In addition, a guide portion 20c is formed on the right side surface of the front stage 20 so as to protrude outward from the banknote stacking surface. In the accumulation portion right side wall 41, a guide groove that is long in the vertical direction is formed corresponding to the guide portion 20c. The guide part 20c guides the slide movement of the front side stage 20 in the vertical direction by moving up and down in the guide groove of the right side wall 41 of the stacking part.

  On the other hand, the front stage 20 is prevented from moving in the front-rear direction by the guide portion 20c and the guide groove, the through hole of the support portion 20a, and the slide shaft 42. Further, the front side stage 20 does not move in the left-right direction between the left side wall portion of the pushing member 10 and the accumulation portion right side wall 41. That is, the front stage 20 moves only in the vertical direction with the position in the front-rear direction fixed.

  The back side stage 30 has a substantially rectangular thin plate shape, and is disposed below the front side stage 20 at a position where a partial area on the front side and a partial area on the back side of the front side stage 20 overlap. . On the left side surface and the back side surface (back surface) of the back side stage 30, guide portions 30a and 30b are formed at positions corresponding to the guide grooves 10a and 10b of the extruding member 10 so as to protrude outside the banknote stacking surface. . These guide portions 30a and 30b guide the sliding movement of the back side stage 30 in the vertical direction relative to the push member 10 by moving up and down in the guide grooves 10a and 10b of the push member 10.

  The rear stage 30 is formed with a through hole elongated in the front-rear direction as a guide hole 30 c at a position corresponding to the boss 20 b of the front stage 20. As shown in FIG. 1B, by attaching a washer having an outer diameter larger than the left-right width of the guide hole 30c to the boss 20b of the front stage 20 that has passed through the guide hole 30c of the rear stage 30, the front side When the stage 20 moves in the vertical direction, the back side stage 30 is also moved in the vertical direction (Z-axis direction). At this time, the back side stage 30 moves while sliding the guide portions 30a and 30b in the guide grooves 10a and 10b of the pushing member 10, and the pushing member 10 does not move in the vertical direction. That is, with respect to the movement in the vertical direction, the back side stage 30 moves together with the front side stage 20 independently of the pushing member 10.

  By the guide portion 30a on the left side surface of the back side stage 30 and the guide groove 10a on the left side wall portion of the pushing member 10, movement of the back side stage 30 relative to the pushing member 10 in the front-rear direction (X-axis direction) is restricted. When this moves in the front-rear direction, the back side stage 30 also moves in the front-rear direction (X-axis direction). At this time, the rear stage 30 moves in the front-rear direction while moving the guide hole 30c with respect to the boss 20b fixed to the front stage 20, and the front stage 20 does not move. That is, with respect to the movement in the front-rear direction, the back side stage 30 moves together with the pushing member 10 independently of the front side stage 20.

  Although FIG. 1 shows an example in which the front side stage 20 and the back side stage 30 are supported substantially horizontally, the support method is not limited to this. For example, when banknotes are stacked from the right side, the front side stage 20 and the back side stage 30 that form the banknote stacking surface are supported in an inclined state so that the banknote stacking surface is inclined higher on the left side. It does not matter.

  The sliding movement of the pushing member 10 in the front-rear direction is controlled by a driving device such as a motor. Similarly, the vertical sliding movement of the front stage 20 is also controlled by a driving device such as a motor. On the other hand, the rear stage 30 is forcibly moved in the vertical direction as the front stage 20 is moved, and is forcibly moved in the front and rear direction as the pusher member 10 is moved.

  By controlling the position (height) of the front side stage 20 in the vertical direction, when stacking banknotes is started, the banknote stage is moved to a predetermined upper position and discharged from the transport path into the stacking unit. Banknotes can be received and accumulated on the banknote stage. As the bills are stacked, the bill stage can be gradually moved downward according to the number of stacked bills. Further, by controlling the position in the front-rear direction of the pushing member 10, the pushing member 10 is retracted backward so as not to contact the bill while the bills are stacked, and the pushing member is completed when the bills are stacked on the stacking unit. The banknote can be pushed out to the opening side by moving 10 forward.

  With respect to the front side stage 20 whose position in the front-rear direction is fixed at an arbitrary position between the highest position where the banknote stage is at the top and the lowest position at the bottom, Since the back side stage 30 can be moved in the front-rear direction, it is not necessary to move the bill stage to a predetermined position in order to push the accumulated bills forward. As a result, after the banknotes are accumulated, the banknotes can be pushed out immediately, and banknote processing can be performed efficiently.

  Thus, in the stacking unit of the banknote processing apparatus, the front stage 20 that can move up and down, the rear end (back side edge) of the front side stage 20, and the position away from the rear end to the rear (back side). And the pushing member 10 that is movable in the front-rear direction to stack the bills, the pushing member 10 is further from the rear end (back side edge) of the bills stacked on the front side stage 20. When extruding banknotes that are located behind and stacked on the front stage 20, the pushing member 10 moves forward toward the rear end of the front stage 20 while pushing the rear end of the banknotes. That is, the pushing member 10 can freely move in the front-rear direction independently of the front-side stage on the back side from the front-side stage 20 that moves up and down.

  In addition, the back side stage 30 disposed so as to fill the gap between the rear end of the front side stage 20 and the extrusion member 10 moves in the vertical direction together with the front side stage 20 independently of the extrusion member 10. Independently from 20, it moves in the front-rear direction together with the pushing member 10. Thereby, a banknote does not enter between the front side stage 20 and the extrusion member 10, and the process which accumulate | stores and extrudes a banknote on a banknote stage can be performed reliably.

  FIG. 2 is a side view showing a state in which the banknotes stacked on the banknote stage are pushed forward by the pushing member 10. For example, as shown in FIG. 1B, the upper surface of the front stage 20 is defined as the height of the vertical position where the height from the bottom surface of the stacking unit to the upper surface of the front stage 20 is H1. After the first banknote sent from the transport path to the stacking unit is received on the banknote stage in the state where the stacking height is H1, the banknotes stacked on the top as the number of stacked sheets increases. The bill stage is gradually lowered so as to be H1.

  When the banknotes 100a have been accumulated, as shown by the arrows in FIG. 2A, the pushing member 10 and the back side stage 30 move forward to push the banknotes 100a to the opening side. As a result, the banknotes are pushed out in a state where the height from the bottom of the stacking unit to the topmost banknote on the stacked banknotes 100a is H1, and the height from the bottommost banknote to the bottommost banknote is H2. It is. The broken line shown in FIG. 2 is the back position of the pushing member 10 at the time of banknote accumulation, and shows that the pushing member 10 has moved from the position shown by the broken line to the position shown in FIG.

  In the banknote handling apparatus, even when the number of stacked banknotes is larger than that in FIG. 2A, as shown in FIG. 2B, the banknote 100a is pushed out at the position where the banknote stage is lowered according to the number of stacked banknotes. Can be controlled. As a result, the height from the bottom of the stacking unit to the topmost banknote on the stacked banknote 100a is H1, and the height from the bottommost banknote to the bottommost banknote is H3 (H3 <H2). The banknote can be pushed out.

  In this way, in the banknote handling apparatus, the height of the banknote stage is changed according to the number of banknotes stacked in the stacking unit, and the banknotes can be pushed out to the opening side at each position where banknote stacking is completed. The banknotes can be pushed out immediately after the banknotes are accumulated.

  In addition, although the example which extrudes a banknote at the position where the position of the up-down direction of a top banknote becomes the same was shown in FIG. 2 irrespective of the number of accumulation | stacking, the position of the banknote stage at the time of extruding a banknote is changed by setting. be able to.

  For example, after moving the banknote stage to a predetermined position so that the height of the lowest banknote is always the same regardless of the number of stacked sheets, that is, the vertical position of the banknote stage is always the same position. It is also possible to set to extrude bills. Further, for example, the position of the banknote stage when extruding banknotes can be set according to the user's eyes and preferences of the banknote processing apparatus according to the height at which the user can easily pull out banknotes.

  FIG. 3 is a plan view showing a state in which the banknotes stacked on the banknote stage are pushed forward by the pushing member 10. FIG. 3B shows a case where banknotes 100c having a shorter length in the longitudinal direction, that is, the longitudinal direction of the apparatus (X-axis direction) than the banknote 100b shown in FIG. The broken line shown in FIG. 3 is the back surface position of the pushing member 10 at the time of banknote accumulation, and indicates that the pushing member 10 has moved from the position shown by the broken line to the position shown in FIG.

  For example, when the stacking of banknotes is finished, as shown by an arrow in FIG. 3A, the pushing member 10 and the back side stage 30 move forward by a distance D2 to push the banknote 100b to the opening side. As a result, the banknote 100b is pushed out to a position where the front end (opening side front end) is at a distance D1 from the back surface position of the pushing member 10 at the time of banknote accumulation indicated by a broken line.

  As shown in FIG. 3 (b), when the length of the stacked banknotes 100c in the longitudinal direction is short, the pushing member 10 and the back side stage 30 have a longer distance D3 (D3) than that in FIG. 3 (a). > D2) It moves and the front end of the banknote 100c is pushed out to the position where the distance from the back surface position of the pushing member 10 at the time of banknote accumulation is D1, as in FIG.

  As described above, in the banknote handling apparatus, the movement distance (extrusion amount) of the extruding member 10 is changed according to the longitudinal direction of the banknotes accumulated in the stacking unit, that is, the length of the extruding direction for extruding banknotes. It can be pushed out so that the front end is always in the same position. However, the amount of bills pushed out can be changed by setting. For example, the same extrusion amount can always be used regardless of the size of the bill. Also, the amount of extrusion can be set in accordance with the position where the user of the banknote handling apparatus can easily extract the banknote, similarly to the banknote stage.

  In order to prevent the accumulated bills from collapsing and jumping forward from the opening when the pushing member 10 and the back side stage 30 are moved in a state where the bills are accumulated on the bill stage and the bills are pushed forward. The side stage 20 may be shaped to push up the front of the banknote. FIG. 4 is a schematic diagram showing an example of a structure for pushing up the opening side of banknotes stacked on the stage. As shown in FIG. 4A, a protrusion 50 that supports a bill is formed on the front end of the front stage 20. The protrusion 50 has a shape as viewed from the side, the rear end being in the same plane as the front side stage 20 and gradually increasing in height toward the front end.

  As shown in FIG. 4A, after the banknotes 100d are accumulated on the banknote stage, the extruding member 10 and the back side stage 30 are moved as shown in FIG. The front end of the banknote 100d is gradually pushed upward along the upper surface of the protrusion 50. Thus, by making the front end side of the banknote 100d lifted at the time of extrusion, it is possible to prevent the banknote 100d from collapsing toward the opening side or jumping out of the opening. Moreover, even if the force which tries to return to the back side acts on the banknote 100d which raised the front end side, the banknote 100d is prevented from collapsing to the back side by supporting the rear end of the banknote 100d by the pushing member 10. be able to.

  In addition, in order to make a banknote into the stable accumulation state also about the left-right direction, it is good also considering the shape of the processus | protrusion 50 as a shape which becomes so low that it becomes inner side when it sees from an apparatus front. Thereby, when the banknotes accumulated on the banknote stage are viewed from the front of the apparatus, the left and right ends of the banknotes can be lifted and supported so that the banknotes are not easily collapsed in the left-right direction. In addition, according to the structure of the stacking unit and the banknote stage, if the banknote can be in a stable stacking state, when viewed from the front, the height pushed up at the left end and the right end of the banknote is different, The shape of the protrusion 50 viewed from the front may be asymmetrical. For example, when the banknotes accumulated on the banknote stage are viewed from the front, when the banknote accumulation state is stabilized by lifting the left side or the right side of the banknote and bringing it to the other side The shape of the protrusion 50 is asymmetrical so as to realize this support state.

  The extruding member 10 and the back side stage 30 are slid in the front-rear direction between the accumulating position and the extruding position, with the position when accumulating the banknotes being the accumulating position and the position where the banknotes are extruded being the extruding position. After the accumulation, the timing for starting the movement from the accumulation position to the extrusion position can be changed by setting. Specifically, when banknote processing is completed, when stacking of banknotes in the stacking unit is completed, when the stacking unit is full and banknotes cannot be stacked, an error occurs in the banknote processing device. Thus, one or a plurality of extrusion start timings can be set, for example, when banknotes can no longer be accumulated in the accumulation unit. In the banknote handling apparatus, the banknotes are pushed out by detecting that the banknotes accumulated on the banknote stage are in a state satisfying a predetermined condition set according to the set contents.

  The timing at which the pushing member 10 and the back side stage 30 that have moved to the pushing position return to the stacking position can also be changed by setting. For example, after the extruding member 10 moves to the extruding position and extrudes banknotes, the setting immediately returns to the stacking position, and after the extruding member 10 moves to the extruding position, the extruding position is removed until the extruded banknotes are extracted. Then, it can be set to return to the stacking position after the banknotes are extracted. Note that the withdrawal of the banknote can be detected by a sensor provided in the stacking unit.

  In the banknote handling apparatus, there are cases where the types of banknotes accumulated in each stacking unit are set in advance, and the types of banknotes stacked in each stacking unit may be set according to the identification result by the identifying unit. Also, information such as denomination information that can specify the size and material of the banknotes accumulated in each stacking unit, damage information that can specify the degree of damage to the banknotes, information such as the number of banknotes stacked in the stacking unit, It is managed in the banknote handling apparatus. In the banknote handling apparatus, one or a plurality of information is selected from information such as denomination information, damage information, and the number of stacked sheets, and the pushing member 10 is moved from the pushing position to the collecting position based on the selected information. It is possible to set a determination condition for the timing to return to.

  For example, a banknote of a denomination that tends to collapse when a large number of sheets are stacked due to its small size is supported by the pushing member 10 at the pushing position until the banknote is pulled out, and the banknote is pulled out. The pushing member 10 is set to return to the accumulation position. Moreover, the banknote of the denomination which is large in size and hardly collapses even when many sheets are stacked is set so that the pushing member 10 returns to the stacking position immediately after pushing out the banknotes. At this time, for a banknote of a denomination with a small size, if the number of stacked sheets is equal to or less than a predetermined number, the pushing member 10 can be set to return to the stacking position immediately after pushing out the banknotes. Similarly, when extruding banknotes that are in a state of being easily collapsed according to the material of the banknotes, the degree of damage, the number of accumulated banknotes, etc., the banknotes are supported by the extruding member 10 at the extrusion position until the banknotes are extracted. Then, after the banknotes are extracted, the pushing member 10 is set to return to the stacking position, and when pushing out the banknotes that are not easily collapsed, the pushing member 10 is immediately returned to the stacking position without waiting for the banknotes to be pulled out. Can be set as follows.

  In addition, information such as the denomination information of the banknote, the damage information, and the number of stacked sheets can be used for the vertical position adjustment of the banknote stage. Specifically, for example, when stacking banknotes, the vertical position of the banknote stage is adjusted according to the thickness of the banknotes and the number of stacked banknotes based on the denomination information. Further, for example, when pushing out a highly damaged banknote based on the banknote damage information, the banknote is pushed out at a position where the banknote stage is lowered than usual. If the banknotes are severely damaged, they will easily catch on the unevenness or impeller in the stacking part during extrusion, and the banknotes may be stacked in a curled state.

  FIG. 8 is a perspective view showing a state of the stacking unit at the push-out position where the pushing member 10 pushes the banknotes stacked on the banknote stage forward. As shown by the arrow, the pushing member 10 slides forward, whereby the bill is pushed out by the front surface of the back surface portion 10c of the pushing member 10, that is, the pushing surface. In addition, in FIG. 8, although the position to which the extrusion surface moved until it contacted the back side edge part of the front side stage 20 is made into the extrusion position, as shown in FIG. The setting can be changed.

  When the pushing member 10 moves forward, the back side stage 30 pushed by the pushing member 10 is forcibly moved forward. At this time, the back stage 30 moves while sliding the guide holes 30c provided on the accumulation surface with respect to the bosses 20b provided on the back of the front stage 20. Thereby, the back side stage 30 can move forward independently of the front side stage 20 below the front side stage 20 where the position in the front-rear direction is fixed.

  FIG. 9 is a perspective view of the pushing member 10 and the accumulation portion left side wall 40 as viewed from the back side. Through holes 10 h are formed in a plurality of ribs formed so as to protrude from the bottom surface of the extrusion member 10. Further, the slide shaft 45 is fixed to the banknote processing apparatus in a state of penetrating each through hole 10 h, and the pushing member 10 is slid back and forth along the slide shaft 45. The movement of the pushing member 10 is controlled by a driving device such as a motor (not shown). The pushing member 10 can be stopped at an arbitrary position in the front-rear direction between the accumulation position shown in FIG. 6 (the rearmost position) and the position shown in FIG. It has become.

  For example, as shown in FIG. 9, a plate 11 having a through hole 11 a elongated in the vertical direction is fixed to the back side of the back surface portion 10 c of the push member 10. Then, one end of a long plate-shaped link plate (not shown) is fixed to a rotating shaft of a motor (not shown), and a shaft provided on the other end side of the link plate is inserted into the through hole 11a and inserted into the through hole 11a. The shaft is rotated by a motor as shown by the broken line in FIG. Thereby, the extruding member 10 whose movement other than the front-rear direction is restricted by the through-hole 10 h of the bottom rib and the slide shaft 45 can be slid in the front-rear direction. Similarly, the vertical slide movement of the front stage 20 can be performed by converting the rotational movement of the motor into the vertical movement using a mechanism including a link plate.

  In this case, the stop position of the pushing member 10 and the stop position of the front side stage 20 are controlled by providing a sensor for detecting the positions of the pushing member 10 and the front side stage 20 and controlling the rotation of the motor that rotates the link plate. The mode performed by doing, and the mode performed by controlling the rotation angle of a link plate using a stepping motor etc. may be sufficient. However, the method of slidingly moving the push member 10 and the front stage 20 is not particularly limited, and a configuration using a rack and a pinion may be used as long as it can be stopped at any position while being slid.

  FIG. 10 is a perspective view of the front side stage 20 and the rear side stage 30 shown in FIGS. FIG. 11 is a perspective view of the same front side stage 20 and back side stage 30 as viewed from the back side. The front stage 20 is provided with a rib on the back surface of the back stage 30 to ensure strength, whereas the back stage 30 is moved on the back side, so that the back surface has a flat shape. ing.

  Three guide portions are provided on the left side surface of the back side stage 30. One is constituted by a roller 30d that is rotatably supported on the back side stage 30, and the remaining two guide portions 30a are formed to protrude from the bill stacking surface to a substantially rectangular shape and are provided with ribs on the back side. Yes. The back side guide portion 30b of the back side stage 30 has the same structure as the side guide portion 30a.

  Further, a U-shaped notch is formed on the opening side of the front stage 20 so that the banknotes stacked on the banknote stage can be easily grasped from above and below. Similarly, a notch is formed on the rear side stage 30 on the opening side so that the notch of the front side stage 20 is not blocked even when the rear side stage 30 moves most forward.

  In the rear stage 30, a guide hole 30c that is elongated in the front-rear direction and penetrates in the vertical direction is formed in the left region outside the notch. In addition, a through hole 30e that allows the slide shaft 43 to pass through in the front-rear direction is formed in the right region outside the notch on the rear surface of the rear stage 30.

  As shown in FIG. 11, a bearing is formed on the right side of the rear surface of the front stage 20 at a position separated in the front-rear direction, and a slide shaft 43 is fixed to the bearing. The slide shaft 43 is fixed in a state of passing through two through holes 30 e formed in the back side stage 30, and guides the slide movement of the back side stage 30 relative to the front side stage 20. By forming the two through holes 30e of the back side stage 30 at positions separated in the front-rear direction, the back side stage 30 can be supported by the slide shaft 43 so as not to tilt in the front-rear direction with respect to the front side stage 20. It is like that.

  On the left side of the back surface of the front side stage 20, a boss 20b that penetrates the guide hole 30c of the back side stage 30 is formed. As shown in FIG. 11, a washer having an outer diameter larger than the width of the guide hole 30c is fixed to a boss 20b that penetrates the guide hole 30c and protrudes toward the back surface side. As a result, the rear stage 30 can be slid in the front-rear direction with respect to the front-side stage 20 whose position in the front-rear direction is fixed, and the rear side stage 30 is slid in the up-down direction. The side stage 30 is forcibly moved in the vertical direction together with the front side stage 20.

  The banknote stage and the shape of the pushing member 10 may be a shape obtained by changing a part of the shape shown in FIGS. FIG. 12 is a front view illustrating an example of a stacking unit in which the shapes of the extrusion member and the banknote stage are different. FIG. 13 is a perspective view of the banknote stage of the stacking unit shown in FIG. 12 as viewed from above. In FIGS. 12 and 13, reference numerals are omitted for the same components as those shown in FIGS. 5 to 11. Further, in FIG. 13, a part of the outer shape of the back surface portion 110 c of the pushing member 110 is indicated by a broken line, and only the configuration for explaining the feature of the banknote stage is shown, and the other configuration is omitted.

  In the example shown in FIG. 12, the structure on the right side surface of the back surface portion 110c of the pushing member 110 is different from the pushing member 10 shown in FIG. Specifically, the right side surface of the back surface portion 110c is located at the position inside the stacking unit from the stacking unit right side wall 141 fixed to the banknote handling apparatus. For this reason, a plurality of protrusions 110g having a triangular section that is long in the front-rear direction are provided on the right side surface of the back surface part 110c, but the corresponding groove 146a that is long in the front-rear direction is not the right-side wall 141 of the stacking unit. , Provided on the back wall 146 of the stacking unit.

  As shown in FIG. 13, a thin plate-shaped shielding portion 120 d that protrudes rearward is formed on the right side of the rear edge of the front stage 120. The shielding portion 120d having an inclined surface on the left side reaches the rear end of the rear stage 130 so as to cover the upper right end of the rear stage 130 in the front-rear direction. In the region from the shielding part 120d to the front end of the front stage 120, the gap with the accumulation part right side wall 141 is shielded by the front stage 120, and while the rear stage 130 slides in the front-rear direction together with the pushing member 110, This shielding state is maintained. Specifically, the back surface portion 110c of the pushing member 110 has a shape that can be moved forward while avoiding the shielding portion 120d, and the pushing member 110 pushes the back side stage 130 while avoiding the shielding portion 120d and moves forward. It moves to an extrusion position and pushes a banknote to the opening side.

  As shown in FIG. 13, the three guide portions 130 a provided on the left side surface of the back-side stage 130 have a structure that protrudes outward from the integration surface and has ribs on the back surface. In addition, a guide portion 120c is formed on the right side surface of the front stage 120, and a guide groove 141c that is long in the vertical direction is formed in the accumulation portion right side wall 141 correspondingly. Further, a support portion 120a for supporting the front side stage 120 is provided at a substantially central position between the front end of the front side stage 120 and the rear end of the shielding portion 120d. Correspondingly, the stacking unit right side wall 141 is provided. A long groove 141b is formed in the vertical direction. Although FIG. 13 shows an example in which one guide portion 120c is provided on the front stage 120, a mode in which guide portions are provided at a plurality of locations including the shielding portion 120d may be used.

  In the present embodiment, an example in which a protrusion for preventing the banknote from entering the gap is provided on the side surface of the extrusion member 10 and a groove corresponding to the protrusion is provided on the wall surface fixed to the banknote processing apparatus has been described. Is not limited to an aspect provided only on the pushing member 10 and the wall surface of the banknote processing apparatus, and is provided on the surface where the front side stage 20 and the back side stage 30 are in contact, that is, the back side of the front side stage 20 and the top surface of the back side stage 30. It may be an aspect.

  Moreover, although the banknote stage showed the example formed by two stages, the front side stage 20 and the back side stage 30, the structure of the banknote stage is not limited to this. For example, the front side stage 20 may be elongated in the front-rear direction, and the back side stage 30 may be omitted. For example, it is good also as a structure which forms a banknote stage by the front side stage 20 and several back side stages. Specifically, for example, the rear stage 30 is divided into two parts, and these are connected by bosses and guide holes as in the front stage 20 and the rear stage 30 shown in FIG. Structure.

  Moreover, although the aspect which controls the slide movement of the up-down direction of a banknote stage by drive devices, such as a motor, the aspect by which an up-down direction slide movement of a banknote stage is performed by elastic members, such as a spring member, may be sufficient. . Specifically, for example, when banknotes are not stacked on the banknote stage, the vertical position of the banknote stage is at the top stacking start position for receiving banknotes on the banknote stage at the start of stacking. When the stacking of the banknote is started, the banknote stage gradually slides downward according to the number (weight) of banknotes stacked on the banknote stage, finishes stacking the banknotes on the stacking unit, and moves the banknotes forward. When the banknote is extracted after being pushed out, the support portion 20a of the front stage 20 is supported by the spring member so that the banknote stage returns to the accumulation start position. By adopting such a structure, even when the vertical size of the stacking unit is increased so that a large number of banknotes can be stacked, the banknote is always received on the banknote stage at the stacking start position at the start of stacking. Can do. As the number of stacked sheets increases, the banknote stage can be gradually slid downward according to the weight of the banknotes. When banknotes need to be pushed out, for example, when the banknotes are stacked on the stacking unit, the banknotes can be pushed out regardless of the vertical position of the banknote stage.

  Further, a mode is shown in which the back side stage 30 is forcibly moved in the front-rear direction by moving the push-out member 10 in the front-rear direction with the guide portion 30 a of the back-side stage 30 inserted into the guide groove 10 a of the push-out member 10. However, the back stage 30 may be moved using an elastic member such as a spring member. For example, a compressed coiled spring member is inserted between the through hole 30e on the front surface side of the rear stage 30 shown in FIG. 11 and the support hole on the front end portion of the front stage 20 that supports the slide shaft 43. 43 arrange | positions in the form which penetrates the inside of a coil. By this spring member, the back side stage 30 is urged toward the back side pushing member 10 from the front side stage 20 whose position in the front-rear direction is fixed. Thereby, when the pushing member 10 moves in the front-rear direction, the back side stage 30 biased by the spring member can be moved together with the pushing member 10. In addition, when it is set as the structure which urges the back side stage 30 to the extrusion member 10 side by a spring member in this way, it is set as the structure which abbreviate | omitted the guide part 30a of the back side stage 30 and the guide groove 10a of the extrusion member 10. Also good.

  As described above, according to the banknote handling apparatus according to the present embodiment, the banknote stage provided in the stacking unit is slidable in the front-rear direction and the front-side stages 20 and 120 that are slidable in the vertical direction. And the rear side stages 30 and 130 that slide in the vertical direction together with the front side stages 20 and 120 and slide in the front and rear direction together with the extrusion member 110. The front-side stages 20 and 120 and the back-side stages 30 and 130 on which bills are stacked in the stacking unit can be moved to arbitrary positions in the vertical direction, and the back-side stage 30 can be moved to arbitrary positions in the vertical direction. , 130 and the pushing members 10, 110 can be moved forward. Thereby, it is possible to move the banknote stage up and down according to the number of banknotes to be stacked, and the banknotes are pushed out by the extruding members 10 and 110 at an arbitrary position regardless of the vertical position of the banknote stage. be able to. Since it is not necessary to move the banknote stage to a predetermined position in order to push out banknotes, banknotes can be stacked and pushed out efficiently in a short time.

  In addition, the amount of banknotes to be pushed is changed according to the type and state of the banknotes accumulated in the stacking unit, or the timing for returning the pushing member 10 that has moved from the stacking position to the pushing position and pushed out banknotes to the stacking position is changed. You can do it. For example, when the accumulated banknotes are likely to collapse depending on the size, material, damage condition, number of stacked sheets, etc., the banknotes can be supported by the pushing member 10 until the banknotes are extracted. And it can be done reliably.

  As described above, the paper sheet processing apparatus according to the present invention is useful for efficiently extruding the accumulated paper sheets to the opening side in an accumulating unit capable of accumulating many paper sheets.
