  However, in the paper sheet storage cassette of the type in which the storage and feeding mechanism is not provided in the housing of the paper sheet storage cassette and the shutter mechanism is provided at the outlet of the paper sheet storage cassette. The shutter mechanism tends to break down, and this shutter mechanism has a problem that it easily causes various troubles. Further, in such a paper sheet storage cassette, after opening the outlet / inlet by the shutter mechanism of the paper sheet storage cassette, the paper sheet of the paper sheet storage cassette is stored by the storage feeding mechanism provided in the paper sheet processing apparatus. Although the paper sheets stored in the storage section are fed out, there is a problem that the paper sheet feeding method by such a storage and feeding mechanism tends to cause various troubles.

  For example, in a paper sheet storage cassette as shown in Patent Document 1 or the like, when a paper sheet jam occurs at a position where a roller of the storage and feeding mechanism is provided, the paper sheet storage cassette is When the roller is removed from the paper sheet processing apparatus, the roller is completely fixed by the lock mechanism, and there is a problem that it is difficult to manually take out the paper sheet in which the jam has occurred from the storing and feeding mechanism. For this reason, this type of paper sheet storage cassette must be provided with a dedicated mechanism for taking out from the storage and feeding mechanism a paper sheet that has become clogged at a position where the roller of the storage and feeding mechanism is provided.

  Further, in the paper sheet storage cassette as described above, when the lock mechanism for restricting the rotation of the rollers of the storage and feeding mechanism is not provided, the paper sheet storage cassette is removed from the paper sheet processing apparatus. However, since the roller can freely rotate in both the paper feeding direction and the paper feeding direction, anyone can rotate the paper in the paper feeding direction. The paper sheets stored in the paper sheet storage section can be extracted, which causes a problem in crime prevention.

  The present invention has been made in consideration of such points, and when the paper sheet storage cassette is removed from the paper sheet processing apparatus, the roller can be rotated in the paper sheet ejection direction. Therefore, the paper sheets stored in the paper sheet storage unit can be prevented from being pulled out by, for example, the theft, and the paper sheets are clogged at the location where the rollers of the storage and feeding mechanism are provided. Even in such a case, after removing the paper sheet storage cassette from the paper sheet processing apparatus, the paper sheet can be cleared by rotating the roller in the paper loading direction. It is an object of the present invention to provide a storage cassette and a paper sheet processing apparatus including the paper sheet storage cassette.

  The paper sheet storage cassette according to the present invention is a paper sheet storage cassette that is detachably stored in a paper sheet processing apparatus that processes paper sheets, from the outside of the housing to the inside.

A storage / feeding mechanism having a roller for feeding the paper sheets stored in the paper sheet storage unit to the storage unit, and a roller rotation regulating mechanism for regulating rotation of the rollers of the storage / feeding mechanism; The paper sheet storage cassette is mounted on the paper sheet processing apparatus. The roller is rotated in both the paper feeding direction and the paper feeding direction, and when the paper sheet storage cassette is removed from the paper sheet processing apparatus, the roller is moved only in the paper feeding direction. And a roller rotation restricting mechanism for restricting the rotation of the roller to rotate.

  According to such a paper sheet storage cassette, the roller rotation restricting mechanism rotates the roller in both the paper feeding direction and the paper feeding direction when the paper sheet storage cassette is mounted on the paper sheet processing apparatus. On the other hand, when the paper sheet storage cassette is removed from the paper sheet processing apparatus, the rotation of the roller is restricted so that the roller rotates only in the paper sheet loading direction. For this reason, when the paper sheet storage cassette is removed from the paper sheet processing apparatus, the rollers cannot be rotated in the paper sheet discharge direction, so that the paper sheets stored in the paper sheet storage unit are, for example, It can be prevented from being extracted by a theft or the like. Further, even when a paper sheet is jammed at the location where the roller of the storage and feeding mechanism is provided, after removing the paper sheet storage cassette from the paper sheet processing apparatus, the roller is inserted in the paper loading direction, for example. By manually rotating the paper sheet, it is possible to eliminate such paper jams.

  In the paper sheet storage cassette of the present invention, the roller rotation restricting mechanism includes a shaft that rotates in synchronization with the roller of the storage and feeding mechanism, and a lock member that is provided movably in the vicinity of the shaft. When the paper sheet storage cassette is stored in the paper sheet processing apparatus, the lock member is separated from the shaft, and when the paper sheet storage cassette is removed from the paper sheet processing apparatus, the lock member is separated. The member engages with the shaft, and the lock member rotates the shaft in the paper feeding direction but does not rotate in the paper feeding direction when the shaft is engaged. A shape is preferred. According to such a paper sheet storage cassette, the configuration of the roller rotation regulating mechanism that regulates the rotation of the rollers of the storage and feeding mechanism can be simplified.

  In this case, the lock member has a recess, and the shaft is inserted into the recess of the lock member when the sheet storage cassette is removed from the sheet processing apparatus. More preferably, when the shaft is inserted, the shaft is rotated in the paper feeding direction but not rotated in the paper feeding direction.

  Here, when the shaft is inserted into the recess of the lock member, the shaft is partially planar in the circumferential direction at a location where the shaft comes into contact with the recess, and the recess is formed when the shaft is inserted. The first side surface portion and the second side surface portion facing each other extend substantially parallel to the axis, the first side surface portion has a substantially planar shape, and the second side surface portion is an opening of the recess. It has a tapered shape that spreads toward the portion, and when the shaft is about to rotate in the paper discharge direction, the planar portion of this shaft abuts on the first side surface portion of the recess. The rotation of the shaft is restricted by this, and when the shaft is about to rotate in the sheet loading direction, the planar shape portion of the shaft comes into contact with the second side surface portion of the concave portion, thereby rotating the shaft. To be allowed Masui.

  The paper sheet storage cassette is provided with a pinion member that meshes with a rack member provided in the paper sheet processing apparatus when the paper sheet storage cassette is stored in the paper sheet processing apparatus. Preferably, the pinion member is connected to a lock member of the roller rotation regulating mechanism, and the lock member moves when the pinion member meshes with the rack member and rotates. .

As shown in FIG. 1, in the paper sheet storage cassette 10, a dispensing inlet 16 is provided on the upper surface of the housing 12. The outlet / inlet 16 is used to input paper sheets from the outside of the housing 12 (specifically, the conveyance unit 4 of the paper sheet processing apparatus 1) to the inside and to supply paper sheets from the inside of the housing 12 to the outside. To be used to throw out. In addition, a grip 14 is provided on the upper part of the paper sheet storage cassette 10, and the operator can carry the paper sheet storage cassette 10 by holding the grip 14. .

  Next, an outline of the internal configuration of the paper sheet storage cassette 10 will be described with reference to FIG. As shown in FIG. 2, a stage 30 is provided inside the housing 12 of the paper sheet storage cassette 10, in which paper sheets thrown in from the outside of the housing 12 are stacked by the outlet 16. Yes. The stage 30 is configured to reciprocate in the vertical direction inside the housing 12, that is, to move up and down. Further, as shown in FIG. 2, guide members 31 and 32 extending in the vertical direction are provided so as to cover the range in which the stage 30 moves up and down, and the paper sheets accumulated on the stage 30 are guided members 31 and 32. Thus, the position is not shifted from the state of being accumulated on the stage 30.

  A stage driving mechanism (not shown) for moving the stage 30 up and down is connected to the stage 30. The stage driving mechanism is configured to lower the stage 30 when a paper sheet is inserted into the housing 12 from the outside. On the other hand, the stage drive mechanism raises the stage 30 when the paper sheets are thrown from the inside of the housing 12 to the outside. These stage 30, guide members 31, 32, and stage drive mechanism constitute a paper sheet storage unit.

  A storage and feeding mechanism is provided inside the housing 12. This storage / feeding mechanism feeds the sheets fed from the outside of the housing 12 through the dispensing inlet 16 onto the stage 30 and feeds the sheets stacked on the stage 30 to the dispensing inlet 16. It has become. The storage / feeding mechanism includes a feed roller 20, a gate roller 22, and a kicker roller 24 provided in an upper region inside the housing 12. These feed roller 20, gate roller 22 and kicker roller 24 are a pair of left and right when viewed from the right side of FIG. The feed roller 20 and the gate roller 22 are in contact with each other, and a nip portion is formed between the feed roller 20 and the gate roller 22.

  The kicker roller 24 is provided at a position directly above the stage 30. The kicker roller 24 is provided with a shaft 24a, and rotates about the shaft 24a. Specifically, the kicker roller 24 is configured to rotate counterclockwise in FIG. 2 when paper sheets are thrown from the inside of the housing 12 to the outside. The kicker roller 24 moves the uppermost sheet among the sheets stacked on the stage 30 when the stage 30 is raised when the sheet is thrown out from the inside of the housing 12. The sheet is brought into contact with the surface of the paper and kicked out to the nip portion between the feed roller 20 and the gate roller 22 (that is, toward the right in FIG. 2).

  The feed roller 20 is provided with a shaft 20a, and rotates about the shaft 20a. Specifically, the feed roller 20 rotates clockwise in FIG. 2 when a paper sheet is inserted from the outside of the housing 12 into the paper sheet conveyance path 18 (described later) from the outlet 16. Then, the paper sheets sent to the feed roller 20 are sent onto the stage 30. On the other hand, the feed roller 20 rotates counterclockwise in FIG. 2 when paper sheets are thrown from the inside of the housing 12 to the outside, and the kicker roller 24 causes a gap between the feed roller 20 and the gate roller 22. The paper sheet sent to the nip portion is sent to the paper sheet conveyance path 18. The feed roller 20 is continuously rotated clockwise or counterclockwise in FIG. 2 by connecting a feed roller driving mechanism (not shown) to the pulley 44.

  The gate roller 22 is provided so as to abut against the feed roller 20 as shown in FIG. The gate roller 22 is provided with a shaft 22a. The position of the shaft 22a is fixed and does not rotate. A torque limiter (not shown) is disposed between the gate roller 22 and the shaft 22a. This torque limiter allows rotation of the gate roller 22 relative to the shaft 22a when a force greater than a preset torque is applied to the gate roller 22 in the circumferential direction. On the other hand, the torque limiter is adapted to interlock the gate roller 22 and the shaft 22a when the circumferential force applied to the gate roller 22 is smaller than the set torque. That is, in this case, since the shaft 22a is fixed, the gate roller 22 does not rotate.

  Since the torque limiter as described above is provided between the gate roller 22 and the shaft 22a, when the paper sheet is not fed to the nip portion between the feed roller 20 and the gate roller 22, the above-described torque limiter is provided. In this way, the feed roller 20 is continuously rotated by the feed roller driving mechanism, and the feed roller 20 and the gate roller 22 are in contact with each other. become. Since the accompanying force applied to the gate roller 22 is larger than the set torque in the torque limiter, the gate roller 22 is allowed to rotate with respect to the shaft 22a, and the gate roller 22 is rotated with the feed roller 20.

  On the other hand, when a sheet of paper is fed to the nip portion between the feed roller 20 and the gate roller 22, the sheet is sandwiched between the feed roller 20 and the gate roller 22. Is not applied by the feed roller 20, and the circumferential force applied to the gate roller 22 is smaller than the set torque. For this reason, the gate roller 22 and the shaft 22a are interlocked by the torque limiter, and the shaft 22a is fixed, so that the gate roller 22 also does not rotate. As described above, when the paper sheet is fed from the paper sheet conveyance path 18 to the stage 30 by the feed roller 20 or the paper sheet on the stage 30 is fed to the paper sheet conveyance path 18, the gate roller 22 will not rotate.

  The paper sheet transport path 18 is provided so as to extend from the nip portion between the feed roller 20 and the gate roller 22 to the discharge inlet 16. A plurality of guide rollers 25, 26, and 27 are provided in such a paper sheet conveyance path 18, and the paper sheets that are input from the outside of the housing 12 to the outlet / inlet 16 enter the paper sheet conveyance path 18. Along with the guide rollers 25, 26 and 27, the feed roller 20 and the gate roller 22 are fed to the nip portion. Further, when the paper sheet is thrown out from the inside of the housing 12, the paper sheet fed from the nip portion between the feed roller 20 and the gate roller 22 by the feed roller 20 is the paper sheet. Guide rollers 25, 26, and 27 are sent along the conveyance path 18 to the outlet / inlet 16.

  In addition, a beating blade impeller (not shown) is provided in the vicinity of the feed roller 20 and the gate roller 22 inside the housing 12. This bill beating impeller is made of, for example, rubber, and is adapted to strike paper sheets fed from the feed roller 20 to the stage 30. In addition, a stiffness member (not shown) is provided in the vicinity of the feed roller 20 and the gate roller 22 inside the housing 12. The stiffening member is made of, for example, a metal such as stainless steel, and a paper sheet fed from the feed roller 20 to the stage 30 is deformed into a wave shape to be stiffened.

  Further, the paper sheet storage cassette 10 is provided with a roller rotation restricting mechanism for restricting the rotation of the feed roller 20 of the storing and feeding mechanism. Details of such a roller rotation restricting mechanism will be described with reference to FIGS.

A shaft 44a is attached to the pulley 44, and the pulley 44 can rotate in both the clockwise and counterclockwise directions of FIG. 2 around the shaft 44a.

  A circulating belt 40 made of, for example, a rubber belt is stretched around these pulleys 42 and 44. For this reason, when the sheets are fed into the casing 12 of the sheet storage cassette 10 from the outside to the inside, the pulley 44 is driven by the feed roller driving mechanism, and the pulley 42 and the feed roller 20 are circulated accordingly. The belt 40 rotates in the clockwise direction in FIG. On the other hand, when the paper sheets are discharged from the inside of the housing 12 of the paper sheet storage cassette 10 to the outside, the pulley 44 is driven by the feed roller driving mechanism, and the pulley 42 and the feed roller 20 are circulated accordingly. The belt 40 rotates in the counterclockwise direction of FIG. When the rotation of the pulley 44 is regulated by a lock member 46 described later, that is, when the pulley 44 is fixed so as not to rotate by the lock member 46, the rotation of the pulley 42 is also regulated so that the pulley 42 becomes coaxial. The rotation of the attached feed roller 20 is also restricted. In this case, even if the feed roller 20 is manually rotated, for example, the feed roller 20 remains stopped.

Yes. The recess 46b provided in the lock member 46 rotates the shaft 44a in the paper feeding direction (the clockwise direction in FIGS. 2 and 3) when the shaft 44a of the pulley 44 is inserted. However, the shape is such that the sheet is not rotated in the paper ejection direction (counterclockwise direction in FIGS. 2 and 3). Details of the shape of the recess 46b will be described later.

  As shown in FIG. 3, a spring 56 is attached to the upper part of the lock member 46, and this spring 56 is fixed to the inner wall of the housing 12 of the paper sheet storage cassette 10. 54 is attached. Here, the spring 56 provided between the lock member 46 and the fixing member 54 is always applied with a force to be compressed. For this reason, the lock member 46 is always moved upward in FIG. The force is energized towards. That is, when no downward force is applied to the lock member 46, the lock member 46 is pulled upward by the spring 56, and the shaft 44a of the pulley 44 is inserted into the recess 46b of the lock member 46. (See FIGS. 3A and 3B). On the other hand, when the lock member 46 is pulled downward against the upward pulling force of the spring 56 by the cam member 50 described later, the lock member 46 is rotated in the clockwise direction of FIG. 3 about the shaft 46a. The shaft 44a of the pulley 44 comes off from the recess 46b of the lock member 46 (see FIG. 3C).

  Next, details of the configuration of the lock member 46 and the shaft 44a of the pulley 44 in the roller rotation restricting mechanism shown in FIG. 3 will be described with reference to FIGS. Here, FIG. 4A is a view showing a state when the shaft 44a of the pulley 44 is inserted into the recess 46b of the lock member 46, and FIG. 4B is a view of the pulley 44 from the state shown in FIG. It is a figure which shows the state when rotating the axis | shaft 44a in the insertion direction (clockwise direction in FIG. 4) of paper sheets, (c) is a figure which shows the axis | shaft 44a of the pulley 44 from the state shown to (b). It is a figure which shows a state when it further rotates in the insertion direction of leaves. 5 is a configuration diagram showing details of the configuration of the shaft 44a of the pulley 44 in the roller rotation restricting mechanism shown in FIG. 4, and FIG. 5 (a) shows the shaft 44a of the pulley 44 as viewed from above. FIG. 5B is a cross-sectional view of the shaft 44a of the pulley 44 shown in FIG. In FIG. 5A, the lock member 46 is indicated by a two-dot chain line for reference.

  As shown in FIGS. 4 and 5, especially FIG. 5B, the shaft 44 a of the pulley 44 is arranged in the circumferential direction of the shaft 44 a at a position where it contacts the recess 46 b when inserted into the recess 46 b of the lock member 46. A part of the surface is planar. Specifically, as shown in FIGS. 5 (a) and 5 (b), the shaft 44a of the pulley 44 has a pair of planar portions 44c provided at positions symmetrical to the center of the shaft 44a, and FIG. In the cross section of the shaft 44a as shown in (b), a pair of circumferential portions 44b provided between the pair of planar portions 44c are provided.

  Further, as shown in FIG. 4, the recess 46b of the lock member 46 includes a first side surface portion 46c and a second side surface that face each other and extend substantially parallel to the shaft 44a when the shaft 44a of the pulley 44 is inserted. It has the part 46e and the bottom face part 46d. Here, as shown in FIG. 4, the first side surface portion 46c and the bottom surface portion 46d have a substantially planar shape, and the first side surface portion 46c and the bottom surface portion 46d are substantially orthogonal to each other. The height of the first side surface portion 46c is substantially the same as the diameter of the shaft 44a, while the width of the bottom surface portion 46d is slightly smaller than the diameter of the shaft 44a.

  The second side surface portion 46e has a tapered shape that extends toward the opening of the recess 46b, that is, upward. More specifically, the second side surface portion 46e includes a planar shape portion that is substantially orthogonal to the bottom surface portion 46d, and an inclined portion that is inclined from an intermediate position of the planar shape portion so as to move away from the first side surface portion 46c. And are provided. The height of the second side surface portion 46e is smaller than the diameter of the shaft 44a.

  4A, when the shaft 44a of the pulley 44 is inserted into the recess 46b of the lock member 46, the shaft 44a of the pulley 44 is placed in the paper sheet ejection direction, that is, FIG. When rotated in the direction of arrow P in (a), the planar portion 44c provided on the shaft 44a of the pulley 44 comes into contact with the first side surface portion 46c of the concave portion 46b of the lock member 46. The rotation of the shaft 44a of the pulley 44 is restricted, and the shaft 44a does not rotate any more from the state shown in FIG.

  On the other hand, in the state where the shaft 44a of the pulley 44 is inserted into the recess 46b of the lock member 46 as shown in FIG. 4A, the shaft 44a of the pulley 44 is placed in the paper feeding direction, that is, FIG. When rotated in the direction of arrow Q in a), the planar portion 44 c provided on the shaft 44 a of the pulley 44 abuts on the second side surface portion 46 e of the recess 46 b of the lock member 46. Here, since the second side surface portion 46e has a tapered shape that expands toward the opening portion of the concave portion 46b, that is, upward, the planar shape portion 44c of the shaft 44a becomes the second portion of the concave portion 46b. Even in the case of contact with the side surface portion 46e, the rotation of the shaft 44a is not restricted by the recess 46b, and the rotation of the shaft 44a is allowed. For this reason, the shaft 44a of the pulley 44 rotates in the direction of the arrow Q from the state shown in FIG. 4 (a) to the state shown in FIG. 4 (b), and from the state shown in FIG. When 44a further rotates clockwise in FIG. 4 (b), the state shown in FIG. 4 (c) is obtained. In this way, when the shaft 44a of the pulley 44 is rotated in the sheet feeding direction, that is, in the direction of the arrow Q in FIG. 4A, the rotation of the shaft 44a is caused by the recess 46b of the lock member 46. The shaft 44a is allowed to rotate without being restricted.

  Thus, the lock member 46 rotates the shaft 44a of the pulley 44 in the paper feeding direction when the shaft 44a of the pulley 44 is inserted into the recess 46b, but in the paper feeding direction. Does not rotate.

  As described above, the roller rotation restricting mechanism includes the circulation belt 40, the pulleys 42 and 44, the lock member 46, the cam member 50, the pinion member 52, and the like of the paper sheet storage cassette 10.

  Next, the operation of the paper sheet storage cassette 10 having such a configuration will be described below. Specifically, the operation when the paper sheet storage cassette 10 is mounted on the paper sheet processing apparatus 1 and the operation when the paper sheet storage cassette 10 is detached from the paper sheet processing apparatus 1. Each will be explained.

  First, an operation in a state when the paper sheet storage cassette 10 is mounted on the paper sheet processing apparatus 1 will be described.

  When a paper sheet is put into the housing 12 from the outside, the stage 30 is first lowered by a stage driving mechanism (not shown). As a result, a storage space for paper sheets is provided above the stage 30.

  Thereafter, when the sheets are fed into the housing 12 one by one through the discharge port 16, the sheets are passed through the sheet transport path 18 and the nip portion between the feed roller 20 and the gate roller 22. The paper sheets fed to the nip portion are fed onto the stage 30 by the feed roller 20. At this time, the paper sheet fed from the feed roller 20 to the stage 30 is struck by a bill-tapping impeller (not shown). For this reason, the paper sheets can be quickly dropped onto the stage 30, and the paper sheets are not stacked in the vertical direction on the stage 30, but are stacked in a horizontally stacked state. Further, the paper sheet fed to the nip portion between the feed roller 20 and the gate roller 22 is deformed into a wave shape by a stiffness applying member (not shown). As a result, the paper sheets can be stiff.

  On the other hand, when paper sheets are thrown from the inside of the housing 12 to the outside, the stage 30 is first raised by a stage driving mechanism (not shown). As a result, the sheets stacked on the stage 30 can be brought into contact with the kicker roller 24 of the storage and feeding mechanism. Further, when the stage 30 is raised, the beating blade impeller (not shown) and the firming member (not shown) are retracted from the storing and feeding mechanism, and the paper sheets are ejected while the paper sheets are being thrown out. Does not come into contact with these bill-striking impellers and stiffness-imparting members.

  Then, after the stage 30 is raised, the paper sheets accumulated on the stage 30 come into contact with the kicker roller 24, and then the uppermost sheet among the paper sheets accumulated on the stage 30 by the kicker roller 24. The paper sheet is kicked out to a nip portion between the feed roller 20 and the gate roller 22. The paper sheet sent to the nip portion is sent to the paper sheet transport path 18 by the feed roller 20, and the paper sheet is finally transported to the outlet / outlet 16. As a result, the paper sheet is thrown out of the housing 12 of the paper sheet storage cassette 10.

  Note that the paper sheet storage cassette 10 is used when the paper sheets are input from the outside of the housing 12 to the inside as described above, or when the paper sheets are discharged from the inside of the housing 12 to the outside. Since the sheet processing apparatus 1 is mounted, the pinion member 52 provided in the paper sheet storage cassette 10 and the rack member 60 provided in the paper sheet processing apparatus 1 are positioned as shown in FIG. It becomes a relationship. Therefore, the shaft 44a of the pulley 44 is in a position completely removed from the recess 46b of the lock member 46, and the shaft 44a can be freely rotated in both the clockwise and counterclockwise directions in FIG. . Therefore, the circulation belt 40 stretched around the pulley 44 can be freely circulated and the pulley 42 can also be freely rotated in both the clockwise and counterclockwise directions in FIG. Therefore, the feed roller 20 can be rotated in both the paper feeding direction and the paper feeding direction.

  On the other hand, when the paper sheets stored in the paper sheet storage section of the paper sheet storage cassette 10 are collected, when the paper sheet storage cassette 10 is removed from the paper sheet processing apparatus 1, the paper sheet The pinion member 52 provided in the paper storage cassette 10 and the rack member 60 provided in the paper sheet processing apparatus 1 have a positional relationship as shown in FIG. In this case, an upward force is applied to the lock member 46 by the spring 56, and no force against the pulling force by the spring 56 is applied to the lock member 46. The shaft 44a of the pulley 44 is inserted into the recess 46b of the lock member 46.

  When the shaft 44a of the pulley 44 is inserted into the recess 46b of the lock member 46, as described above, the shaft 44a of the pulley 44 is placed in the paper sheet ejection direction, that is, in the direction of the arrow P in FIG. Can no longer be rotated. For this reason, the feed roller 20 cannot be rotated in the sheet discharge direction. On the other hand, when the shaft 44a of the pulley 44 is inserted into the recess 46b of the lock member 46, the shaft 44a of the pulley 44 is in the direction in which the sheets are loaded, that is, in the direction of the arrow Q in FIG. Can be rotated. For this reason, the feed roller 20 can be rotated in the paper feeding direction.

  Here, even when the paper sheets are jammed in the feed roller 20 when the paper sheets are put into the housing 12 from the outside as described above (that is, the paper sheets in the feed roller 20). (Even if a paper jam occurs), after the paper sheet storage cassette 10 is removed from the paper sheet processing apparatus 1, the door of the paper sheet storage cassette 10 is opened and the housing of the paper sheet storage cassette 10 is opened. By pulling the paper sheet jammed with the feed roller 20 from the inside of the body 12 by hand, the feed roller 20 rotates in the direction in which the paper sheet is loaded, and the jamming of the paper sheet can be eliminated.

  Then, the paper sheet storage cassette 10 is mounted on the paper sheet processing apparatus 1 from the state where the paper sheet storage cassette 10 is removed from the paper sheet processing apparatus 1 as shown in FIG. Initially, as shown in FIG. 3B, the pinion member 52 of the paper sheet storage cassette 10 is engaged with the rack member 60 of the paper sheet processing apparatus 1, and the pinion member 52 rotates, so that The lock member 46 is pulled downward by the cam member 50 against the directional force. When the paper sheet storage cassette 10 is completely attached to the paper sheet processing apparatus 1 as shown in FIG. 3C, the lock member 46 is largely pulled downward by the cam member 50. The shaft 44a of the pulley 44 is completely detached from the recess 46b of the member 46.

  As described above, according to the paper sheet storage cassette 10 of the present embodiment and the paper sheet processing apparatus 1 including the paper sheet storage cassette 10, the circulation belt 40, the pulley 42 of the paper sheet storage cassette 10, 44, the roller rotation restricting mechanism including the lock member 46, the cam member 50, the pinion member 52, etc., when the paper sheet storage cassette 10 is mounted on the paper sheet processing apparatus 1, the feed roller 20 is The feed roller 20 is rotated in both the loading direction and the dispensing direction. On the other hand, when the paper sheet storage cassette 10 is removed from the paper sheet processing apparatus 1, the feed roller 20 is rotated only in the paper sheet loading direction. Regulate the rotation of For this reason, when the paper sheet storage cassette 10 is removed from the paper sheet processing apparatus 1, the feed roller 20 cannot be rotated in the paper discharge direction, so that the paper stored in the paper sheet storage unit. For example, the leaves can be prevented from being extracted by a theft or the like. Even when a paper sheet is clogged at a position where the feed roller 20 is provided, after the paper sheet storage cassette 10 is removed from the paper sheet processing apparatus 1, the feed roller 20 is inserted into the paper sheet. For example, such a paper jam can be eliminated by manually rotating the paper sheet.

  The roller rotation restricting mechanism includes a shaft 44a of the pulley 44 that rotates in synchronization with the feed roller 20, and a lock member 46 that is movably provided in the vicinity of the shaft 44a of the pulley 44, and stores paper sheets. When the cassette 10 is stored in the paper sheet processing apparatus 1, the lock member 46 is separated from the shaft 44a of the pulley 44. When the paper sheet storage cassette 10 is removed from the paper sheet processing apparatus 1, the lock member 46 is the pulley. 44 is engaged with a shaft 44a. Further, the lock member 46 rotates the shaft 44a of the pulley 44 in the paper feeding direction when the shaft 44a of the pulley 44 is engaged, but does not rotate it in the paper feeding direction. It has a shape. According to such a paper sheet storage cassette 10, the configuration of the roller rotation restricting mechanism that restricts the rotation of the feed roller 20 of the storage and feeding mechanism can be simplified.

  In addition, the paper sheet storage cassette and the paper sheet processing apparatus according to the present invention are not limited to the above-described embodiments, and various modifications can be made. For example, as a roller rotation restricting mechanism for restricting the rotation of the feed roller of the storing and feeding mechanism, a circulating belt 40, pulleys 42 and 44, a lock member 46, a cam member 50, a pinion member 52, etc. as shown in FIGS. It is not limited to what consists of. As a roller rotation regulating mechanism that regulates the rotation of the feed roller of the storage and feeding mechanism, when the paper sheet storage cassette is installed in the paper sheet processing apparatus, the feed roller is rotated in both the paper feeding direction and the paper feeding direction. If the rotation of the feed roller is restricted so that the feed roller is rotated only in the paper feeding direction when the paper sheet storage cassette is removed from the paper sheet processing apparatus, the one having another configuration can be used. It can also be used.
