[4. Operation of banknote stacking and feeding device]
Next, the operation of the above-described bill accumulation / delivery device 31A will be described. First, the stacking operation when stacking the bills BL in the bill storage space 40 will be described with reference to FIG. The banknote stacking and feeding device 31A causes the stage 48 to stand by at a position where the uppermost banknote BL is detected by the upper surface sensor 49 during banknote stacking, and rotates the feed roller 43 in the direction indicated by the arrow A in the figure. At this time, the banknote stacking / feeding device 31A rotates the first impeller 46 and the reverse roller 44 together with the shaft 62 in the direction indicated by the arrow B in the drawing. At this time, when the counter shaft 71 (not shown in FIG. 4) is rotated by receiving the driving force from the shaft 62, the second impeller 47 is also rotated in the direction indicated by the arrow B in the drawing. The banknote stacking and feeding device 31 </ b> A expands the tongue piece 46 </ b> A of the first impeller 46 and the tongue piece 47 </ b> A of the second impeller 47 over the entire circumference of the shaft 62.

  In this state, when the banknote BL is transported along the transport path 41 in the cassette, the banknote stacking and feeding device 31A sandwiches the transported banknote BL between the feed roller 43 and the reverse roller 44, These are discharged into the bill storage space 40 by these rotations. The bill BL released into the bill storage space 40 falls with the front end colliding with the bill stopper 45. At this time, the bills BL are accumulated so that the rear ends thereof are hit by the tongue piece 46A of the first impeller 46 and the tongue piece 47A of the second impeller 47, and are pressed onto the stage 48.

  When the stacking of the bills BL is completed, the bill stacking and feeding device 31A rotates the first impeller 46 and the second impeller 47 in the directions indicated by the arrows B, respectively, as shown in FIG. Both the tongue piece 46 </ b> A of the impeller 46 and the tongue piece 47 </ b> A of the second impeller 47 are retracted to the outside of the bill storage space 40. Note that the positions of the first impeller 46 and the second impeller 47 at this time are called retreat positions.

  Next, with reference to FIG. 7, a feeding operation when feeding out the bills BL accumulated in the bill storage space 40 will be described. The banknote stacking and feeding device 31 </ b> A raises the stage 48 in a state where the first impeller 46 and the second impeller 47 are retracted to the retracted position when the banknote is fed, and the uppermost banknote BL is picked up by the picker roller 53. Make contact. Here, the banknote accumulation and delivery device 31A rotates the feed roller 43 in the direction indicated by the arrow C in the figure (the direction opposite to the arrow A). Then, the rotation of the feed roller 43 is transmitted to the picker roller 53 via the drive belt 55, and the picker roller 53 also rotates in the same direction. Thereby, the uppermost banknote BL on the stage 48 is sent out to the feed roller 43 side.

  At this time, the rotation of the motor 72 is not transmitted to the shaft 62 by the one-way clutch, and the first impeller 46, the second impeller 47, and the reverse roller 44 do not rotate. Therefore, the bills BL fed to the feed roller 43 side are fed out to the in-cassette transport path 41 so as to pass between the feed roller 43 and the reverse roller 44 one by one by the rotation of the feed roller 43.

In the impeller gear 78, a gear tooth 91 is formed in a portion 78A on the one surface side in the axial direction of the entire outer periphery, and a protrusion that protrudes radially outward from the outer peripheral surface in a portion 78B on the other surface side in the axial direction. A portion 92 is formed. The convex portion 92 has a rectangular parallelepiped shape suspended from the outer peripheral surface of the impeller gear 78, and has a quadrangular shape when viewed from the axial direction as shown in FIG. The impeller gear 78 is configured to fix the impeller boss 47 </ b> C of the second impeller 47 to a substantially cylindrical portion 78 </ b> B provided with the convex portion 92. Therefore, this portion 78B is hereinafter referred to as an impeller fixing portion 78B.

It has a substantially C-shaped cross section in which an opening 101 connected (that is, connected to the inner peripheral surface 100A) is formed. The opening 101 of the impeller boss 47C has a divergent shape that becomes wider as the distance from the hole 100 increases, and the inner narrowest portion is slightly narrower than the outer diameter of the impeller fixing portion 78B. The impeller boss 47C can expand the narrowest portion of the opening 101 until it becomes larger than the outer diameter of the impeller fixing portion 78B, and has elasticity enough to return to its original shape from that state. Yes.

  The impeller boss 47C has a groove-like recess 102 extending in the axial direction of the impeller boss 47C in the vicinity of the opening 101 on the inner peripheral surface 100A (upstream in the rotational direction). The concave portion 102 is a portion that fits with the convex portion 92 of the impeller fixing portion 78B.

The wall surface 102A is a surface orthogonal (or substantially orthogonal) to the inner peripheral surface 100A of the impeller boss 47C, and the bottom surface 102C is a surface orthogonal (or substantially orthogonal) to the wall surface 102A. The inclined surface 102B is a surface that is inclined from the inner peripheral surface 100A of the impeller boss 47C toward the bottom surface 102C. In other words, the inclined surface 102B is a surface that inclines away from the wall surface 102A as it approaches the inner peripheral surface 100A of the impeller boss 47C. As shown in FIG. 14, the concave portion 102 is configured to be fitted to the convex portion 92 such that the wall surface 102A abuts on the convex portion 92 of the impeller fixing portion 78B. That is, the wall surface 102 </ b> A of the recess 102 is a contact surface that contacts the protrusion 92. When the impeller gear 78 rotates in the direction indicated by the arrow B in the figure, the impeller boss 47C rotates as the wall surface 102A receives a force in the rotation direction indicated by the arrow B in the figure from the convex portion 92. ing.

  Here, the attachment method of the 2nd impeller 47 of such a structure is demonstrated using FIG. When attaching the 2nd impeller 47 to the impeller fixing | fixed part 78B of the impeller gear 78 supported by the shaft 62, as shown to FIG. 15 (A), the opening part 101 of the impeller boss | hub 47C is made into an impeller. While pressing the second impeller 47 in the direction orthogonal to the axis with respect to the impeller fixing portion 78B in a state of facing the convex portion 92 of the fixing portion 78B, the position of the convex portion 92 and the position of the concave portion 102 are matched. The second impeller 47 is rotated to adjust the angle. Then, as shown in FIG. 15 (B), when the opening 101 of the impeller boss 47C expands and the opening 101 becomes larger than the outer diameter of the impeller fixing portion 78B, as shown in FIG. 15 (C). As shown, the impeller fixing portion 78B enters and fits into the hole 100 of the impeller boss 47C, and the opening 81 returns to its original size. At this time, the convex portion 92 of the impeller fixing portion 78B is fitted into the concave portion 102 of the impeller boss 46C, so that the second impeller 47 is fixed so as not to be displaced in the rotational direction with respect to the impeller gear 78. Is done. At this time, the second impeller 47 and the impeller gear 78 are rotatably supported by the shaft 62 so as not to be displaced in the axial direction by a regulating member (not shown) attached to the shaft 62, for example. .

  In the banknote cassette 21, the second impeller 47 is attached in this way. Next, a method for removing the second impeller 47 will be described.

As a result, the inside of the bill storage space 40 is accessible.

  Here, the tongue piece 47A of the second impeller 47 entering the banknote storage space 40 is pinched with a finger or a jig, and the second impeller 47 is rotated in the direction indicated by the arrow B in the drawing while the shaft 62 Pull in the direction perpendicular to the axis (direction indicated by arrow F in the figure). Then, as shown in FIG. 16, the angle of the opposite side to the rotation direction of the convex portion 92 of the impeller fixing portion 78B slides on the inclined surface 102B of the concave portion 102 of the impeller boss 47C, and the opening of the impeller boss 47C is opened. When the portion 101 spreads and the opening 101 becomes larger than the outer diameter of the impeller fixing portion 78B, the second impeller 47 is detached from the impeller gear 78. And by taking out this 2nd impeller 47 through the groove | channel or hole for making the tongue piece 47A of the 2nd impeller 47 provided in the rear guide 51 enter in the banknote storage space 40, Remove from the bill cassette 21.

  Thus, when removing the 2nd impeller 47 from the impeller gear 78, since the convex part 92 remove | deviates from the recessed part 102 so that the angle | corner of the convex part 92 may slide on the inclined surface 102B of the recessed part 102, for example, an inclined surface Compared to removing the convex portion 92 from a concave portion (not shown) having a wall surface parallel to the wall surface 102A instead of 102B, the convex portion 92 can be easily removed from the concave portion 102 with less force. The second impeller 47 can be easily detached from the impeller gear 78.

  Then, the second impeller 47 is taken out from the banknote cassette 21. In the banknote cassette 21, the second impeller 47 can be removed in this way. Then, for example, after the worn tongue piece 47A is removed from the impeller boss 47C and replaced with a new tongue piece 47A, the new second impeller 47 is attached to the impeller fixing portion 78B by the above-described attachment method. The replacement of the second impeller 47 is completed.

[6. Summary and Effect]
As described so far, the banknote depositing and dispensing machine 10 is provided with the opening 81 connected to the hole 80 in a part of the outer periphery of the impeller boss 46 </ b> C of the first impeller 46, and the opening 81 is further connected to the shaft 62. The impeller boss 46 </ b> C has elasticity so that it can be expanded until it becomes larger than the diameter and naturally returns to its original shape from that state. By doing so, in the banknote depositing and dispensing machine 10, the first impeller 46 can be easily attached and detached by pulling or pushing the first impeller 46 in the direction orthogonal to the shaft 62.

  Similarly, the banknote depositing / dispensing machine 10 is provided with an opening 101 connected to the hole 100 in a part of the outer periphery of the impeller boss 47 </ b> C of the second impeller 47, and this opening 101 is an impeller of the impeller gear 78. The impeller boss 47C has elasticity that can be expanded until it becomes larger than the outer diameter of the fixed portion 78B, and naturally returns to its original shape from that state. By doing so, in the banknote depositing and dispensing machine 10, the second impeller 47 can be easily attached and detached by pulling or pushing the second impeller 47 in the direction perpendicular to the axis with respect to the impeller gear 78.

  Furthermore, in the banknote depositing / dispensing machine 10, when the protrusion 82 extending radially inward is provided on the inner periphery of the impeller boss 46 </ b> C of the first impeller 46, and the first impeller 46 is attached to the shaft 62, The protrusion 82 is fitted into a hole 62A formed in the shaft 62 and extending in the direction perpendicular to the axis. By carrying out like this, in the banknote depositing / withdrawing machine 10, the 1st impeller 46 can be fixed so that it may not shift | deviate with respect to the shaft 62 in a rotation direction.

  Further, in the banknote depositing / dispensing machine 10, when the concave portion 102 is provided on the inner periphery of the impeller boss 47 </ b> C of the second impeller 47 and the second impeller 47 is attached to the impeller fixing portion 78 </ b> B of the impeller gear 78. In addition, a convex portion 92 projecting from the outer periphery of the impeller fixing portion 78B is fitted into the concave portion 102. By carrying out like this, in the banknote depositing / withdrawing machine 10, the 2nd impeller 47 can be fixed with respect to the impeller gear 78 so that it may not shift | deviate in a rotation direction.

  In other words, in the banknote depositing and dispensing machine 10, the second impeller 47 that cannot be directly attached to the shaft 62 can be easily attached to and detached from the impeller gear 78 that is rotatably supported by the shaft 62. And it can fix so that it may not shift in the direction of rotation.

  By the way, as shown in FIG. 17, the first impeller 46 and the second impeller 47 rotate at different rotational speeds when the bills BL are stacked in the bill storage space 40 of the bill cassette 21, respectively.

As a result, a load may be applied to the first impeller 46 and the second impeller 47 such that the tongue piece 46A and the tongue piece 47A are pulled in the direction of arrow G (rearward) in the drawing. Further, at the time of bill accumulation, the tongue piece 46A and the tongue piece 47A strike the rear end of the uppermost bill BL accumulated on the stage 48. At this time, the first impeller 46 and the second impeller 47 are used. In contrast, a load is applied such that the tongue piece 46A and the tongue piece 47A are pushed back in the direction of arrow H (upward) in the figure.

  Even in such a case, in the banknote depositing / dispensing machine 10, the projection 82 of the first impeller 46 is fitted in the hole 62 </ b> A of the shaft 62. The convex portion 92 of the impeller gear 78 is fitted to the concave portion 102 of the second impeller 47 so that the convex portion 92 contacts the wall surface 102A of the concave portion 102. Therefore, it is possible to prevent the second impeller 47 from being displaced in the rotational direction with respect to the impeller gear 78.

  Thus, in the banknote depositing / dispensing machine 10, the first impeller 46 and the second impeller 47 can be attached and detached in the direction orthogonal to the axis of the shaft 62, so that the shaft 62 is not detached from the banknote cassette 21. The first impeller 46 and the second impeller 47 can be easily removed from the shaft 62 and replaced. In addition, in the banknote depositing and dispensing machine 10, the first impeller 46 can be fixed so as not to be displaced in the rotational direction with respect to the shaft 62, and the second impeller 47 is rotated with respect to the impeller gear 78. It can be fixed so that it does not shift in the direction.
