Each of the sheet insertion detection sensor 13, the identification unit 15, the passage detection sensor 30, and the storage detection sensor 31 is connected.

(Operation of paper sheet processing equipment)
4 and 5 are explanatory diagrams showing the storing operation of the paper sheet. 6 shows a state in which the upper parallel link mechanism of the drive unit in FIG. 2 is operated, and FIG. 7 is a front view showing a state in which the lower parallel link mechanism is operated. The operation of the embodiment of the present invention will be described below with reference to FIGS.

  Here, it is assumed that 10,000 yen bills are stored in the first storage (A) and thousand yen bills are stored in the second storage (B). When the paper sheet processing apparatus 1 is in a power-on state and a paper sheet or the like is not inserted, the drive unit 40 is in the state shown in FIG. At this time, since the cam 43 is fitted in the recesses 46c and 47a, the arms 44 to 47 are in a parallel state, and the height of the drive unit 40 is minimized.

  In this state, when the paper sheet 100 is inserted from the insertion port of the insertion unit 12, the insertion is detected by the paper sheet insertion detection sensor 13. In response to this detection, the control unit 61 drives the motor driving units 62 and 63 to rotate the motors 28 and 29 and operates the first and second transport units 14 and 16. As a result, the timing belts 14C and 16C rotate in the direction of the arrow shown in FIG. 1, and the paper sheet 100 is conveyed backward by the timing belt 14C.

  In the process in which the paper sheet 100 moves on the timing belt 14C, the authenticating unit 15 determines the authenticity of the paper sheet 100. When it is determined that the paper sheet 100 is a genuine banknote, its type (any one of 10,000 yen, 5,000 yen, 2,000 yen, or 1,000 yen) is determined, and the result is notified to the control unit 61. Then, the rotation of the drive roller 14A is continued. In addition, when the paper sheet 100 is a paper sheet other than a banknote or a banknote that is not in circulation, the control unit 61 rotates the motor 28 in reverse via the motor driving unit 62 to insert the paper sheet 100 into the insertion unit 12. Return to the mouth and let the user recognize that the inserted paper sheet 100 cannot be used.

  The paper sheet 100 determined to be a circulating bill is carried from the first conveyance unit 14 to the second conveyance unit 16 and conveyed so as to be lowered by the timing belt 16C. If the identification unit 15 determines that the paper sheet 100 is 10,000 yen, the control unit 61 does not drive the gate 18 and keeps the gate 18 at the solid line position shown in FIG. At the same time, the controller 61 drives the motor 32 to rotate the drive rollers 33A and 33B, thereby rotating the timing belts 35A and 35B.

  When the paper sheet 100 passes through the second transport unit 16 and the leading edge of the paper sheet 100 reaches the passage detection sensor 30, the passage detection sensor 30 transmits a detection signal to the control unit 61. The control unit 61 stops driving the transport units 14 and 16 based on the detection signal of the passage detection sensor 30.

  The paper sheet 100 (10,000 yen bill) passes through the front surface of the gate 18, passes through the third transport unit 19, and then reaches the timing belt 35 </ b> A. At this time, since the timing belt 35A is rotating, the carried paper sheet 100 is conveyed rightward in the drawing by the timing belt 35A. When the leading end of the paper sheet 100 is detected by the storage detection sensor 31, the control unit 61 stops the motor 32. At this time, the paper sheet 100 is placed on the placement plate 51 as shown in FIG.

  The control unit 61 drives the motor driving unit 65 based on the detection of the storage detection sensor 31 to rotate the stack motor 41. The rotation of the stack motor 41 causes the cam 43 to rotate in the counterclockwise direction of the arm 44, and the roller 43a pushes up the bent piece 44a. As a result, the arms 44 and 45 are opened, the state shown in FIG. 2 is changed to the state shown in FIG. 6, and the mounting plate 51 is raised.

  As shown in FIG. 4B, in the process of raising the placing plate 51, the central portion of the paper sheet 100 is pushed up, and both sides thereof are locked by the guide 36A, so that the paper sheet 100 is bent. Occurs. When the placing plate 51 is further raised in this state, as shown in FIG. 4C, both side portions of the paper sheet 100 come off from the opening of the guide 36A, and the paper sheet 100 is pressed by the placing plate 51. It is pressed against the lower surface of the plate 25.

  Next, when the second sheet 100 of the same type is inserted from the insertion port of the insertion unit 12, it is carried into the drive unit 40 through the third conveyance unit 19 as described above, and is shown in FIG. It is carried in between the mounting plate 51 and the guide 36A shown in a). Thereafter, in the process of changing as shown in FIGS. 4B and 4C, the second sheet 100 is stacked on the lower side of the first sheet 100. Thereafter, similarly, the conveyed paper sheets 100 are sequentially stacked at the lowest level.

  Next, it is assumed that a thousand yen bill as the paper sheet 100 is inserted into the insertion slot of the insertion unit 12. When the paper sheet 100 reaches directly below the identification unit 15, the identification unit 15 determines that the paper sheet 100 is a thousand-yen bill and notifies the control unit 61. The control unit 61 drives the second transport unit 16 and also drives the electromagnetic solenoid 67 via the solenoid driving unit 66 to bring the gate 18 to the vertical position indicated by the broken line in FIG.

  The paper sheet 100 (thousand-yen bill) that has passed through the second transport unit 16 passes through the back surface of the gate 18 and enters the fourth transport unit 20, and then, as shown in FIG. It is carried into the upper surface of 36B. When the leading end of the paper sheet 100 is detected by the storage detection sensor 31, the control unit 61 stops the motor 32.

  The control unit 61 drives the motor driving unit 65 based on the detection of the storage detection sensor 31 to rotate the stack motor 41. The rotation of the stack motor 41 causes the cam 43 to rotate counterclockwise from the state of FIG. 6, and the roller 43 a presses the bent piece 44 a while riding on the bent piece 46 b of the arm 46. As a result, the arms 46 and 47 are changed from the state shown in FIG. 6 to the state shown in FIG. 7, and the pressing plate 54 is lowered. In this process, as shown in FIG. 5B, the pressing plate 54 pushes down the central portion of the paper sheet 100 to bend the paper sheet 100. When the pressing plate 54 is further lowered, as shown in FIG. 5C, both side portions of the paper sheet 100 are detached from the guide 36 </ b> B, and the paper sheet 100 is pressed against the mounting table 21 by the pressing plate 54. Close contact with the bottom surface.

(Effect of embodiment)
According to this embodiment, the following effects can be obtained.
(B) Even if there are a plurality of storages, the drive unit 40 can be shared by the drive unit 40 for stacking the loaded paper sheets 100, so only one motor, reducer, cam, etc. is required. The configuration of the drive mechanism can be simplified. Thereby, since the number of parts can be reduced, it is possible to reduce the size and weight and reduce the cost.
(B) Since the mounting plate 51 and the pressing plate 54 are moved up and down by a parallel link mechanism in which a pair of arms are assembled in an X shape, the horizontal position of the mounting plate 51 and the pressing plate 54 can be maintained. Thus, even if the paper sheets 100 are stacked, it is possible to make it difficult to cause a positional shift.
(C) By changing the length of the cam 43, the elevation width of the mounting plate 51 and the pressing plate 54 can be freely set, and the optimum movable range can be set according to the paper quality of the paper sheet 100 and the like. .
