A final gear 42 is rotatably mounted on a shaft 41 attached to a lower bent portion 31a formed on the substrate 31 of the pushing device 15, and a one-way pulley 46 is fixed to the shaft 41. . The rotational force of the motor 25 is constantly transmitted to the shaft 41 through the central gear 26a, the planetary gear 26b, the intermediate gear 44, and the final gear 42 at a reduced ratio.
Is a one-way type, so that it rotates together with the shaft 41 when the motor 25 rotates in the reverse direction, and relaxes the drive wire 47 when the motor 25 rotates in the normal direction. As shown in FIGS. 3 and 5, one end of the drive wire 47 wound around the pulley 46 is connected to a support shaft 36 a on which a pair of drive links 36 are mounted.
The other end of the drive wire 47 is connected to one end of a spring 48. The other end of the spring 48 is fixed to the substrate 31, and an appropriate tensile force is applied to the drive wire 47 by the spring 48. The push plate 32 is urged toward the substrate 31 by a pair of springs 37 arranged between the substrate 31 and the push plate 32. Although not shown in detail, in this embodiment, four springs 37 are provided between the push plate 32 and the substrate 31 corresponding to the four corners of the push plate 32.

When the final gear 42 rotates in one direction, the shaft 41 rotates in the same direction, but the pulley 46 is not rotated because it is a one-way type, the link member 33 is contracted by the elastic force of the spring 37, and the push plate 32 is It is returned toward the substrate 31. At this time, the support shaft 36a is moved outward, and the drive wire 47 is pulled against the elasticity of the spring 48, so that the drive wire 47 is prevented from relaxing. When the final gear 42 rotates in the reverse direction, the one-way type pulley 46 rotates together with the shaft 41, the driving wire 47 is pulled with respect to the support shaft 36a, and the support shaft 36a is moved inward. Accordingly, the pair of drive links 36 is rotated around the movable shaft 33b in a direction in which the pair of drive links 36 are aligned with each other, against the elasticity of the spring 37. Therefore, the one link member 33 and the other link member 33 are expanded around the support shaft 34, and the push plate 32 is
6 in a direction away from the substrate 31 against the elasticity of
Is pressed. Therefore, the link member 33 is extended, and the push plate 32 is moved downward through the opening 57a. As described above, the push plate 32 approaches or separates from the substrate 31 due to the pulling of the drive wire 47 accompanying the rotation of the final gear 42 in both directions, and the link member 33 performs the expansion and contraction operation with the support shaft 36a as a fulcrum. . While the push plate 32 is moving, the receiving plate 5
The four vertical movements are guided by four guide rails 55 into which the notches 54a fit.

As shown in FIG. 3, the bill stacker 3
0 is a door 52 pivotally mounted on a hinge 52a so that it can be opened and closed,
And a lock device 60 that can be locked and unlocked with a key. The lock device 60 includes a cylinder lock 62 fixed to the door 52,
A lock receiver 39 fixed to the substrate 31 is provided, and the lock lever 63 rotatably attached to the cylinder lock 63 can be disengaged from the lock receiver 39 by operating the cylinder lock 63 with a key. . Therefore, when the cylinder lock 63 is locked after the door 52 is closed, the lock lever 63 is locked to the lock receiver 39 and the banknote 1 cannot be taken out of the cassette 50.

In use, the pair of guide pins 53 of the empty cassette 50 are mounted on the guide rails of the frame 2 and the bill stacker device 30 is pushed into the frame 2 as shown in FIG. The intermediate gear 44 is automatically meshed with the planetary gear 26b of the transfer device 20, so that the driving force of the shaft 25g of the transfer device 20 can be transmitted to the intermediate gear 44 through the center gear 26a and the planetary gear 26b. The impact between the intermediate gear 44 and the planetary gear 26b at the time of meshing is absorbed by the buffer spring 28 via the swing lever 27.

When the bill 1 is inserted into the entrance 11 of the discriminating apparatus 10, the optical or magnetic characteristics of the bill 1 are detected, and the detected data is discriminated by the central controller. For example, in the optical characteristics, it is determined whether or not the amount of transmitted light is within a set value range, and a bill that is out of the set value or a partially-defective bill is not determined to be a true bill, and the bill is inserted. Return to shooter.

When the bill inserted into the entrance 11 of the discriminating apparatus 10 is judged as a true bill in the discriminating apparatus 10, the discriminating apparatus 1
It is sent to the transport device 20 by the transport device within 0. When the bill passes through the exit of the discrimination device 10, the leading end position of the bill is detected by the optical sensor. The optical sensor includes a light emitting element such as a diode and a light receiving element. A detection signal generated from the optical sensor is sent to the central control device, and the central control device sends an operation signal to the motor 25 based on the detection signal to cause the motor 25 to rotate forward.

Since the transport device 20 is driven by the forward rotation of the motor 25, the bills supplied to the connection end 22 a of the transport guide 22 are transported along the transport guide 22 by the transport belt 23.
The sheet is conveyed to the bill stacker device 30. During the forward rotation of the motor 25, the final gear 42 is rotated in one direction via the planetary gear 26b, but the one-way pulley 46 idles, and the link member 33 is contracted by the elastic force of the spring 37. For this reason, the push plate 32 is returned to the press-preparation position toward the substrate 31, and is held in the standby state at the push-preparation position. Further, the bill is arranged on the stopper 57 in the cassette 50 along the guide plate 58 from the inlet 59. Although not shown, a push start sensor for detecting that the rear end of the bill 1 has completely passed through the transport device 20 and reached the push position on the stopper 57 in the push device 15 is provided. When the push-in start sensor generates a detection signal, the central controller controls the motor 2 based on the detection signal of the push-in start sensor.
5 is reversed. Therefore, when the banknote 1 sent from the transport device 20 reaches the stopper 57, the motor 25
Is reversed, and the final gear 42 rotates in the opposite direction. For this reason, the one-way type pulley 46 rotates together with the shaft 41, and the driving wire 47 is pulled on the support shaft 36 a, and the one link member 33 and the other link member 33 are expanded around the support shaft 34. , The pressing plate 32 is a spring 5
6 in a direction away from the substrate 31 against the elasticity of
To move from the retracted position in the first storage section 13 to the extended position in the second storage section 14. For this reason, the bills arranged on the stopper 57 in the first storage unit 13
By the movement of the push plate 32, the push plate 32 gets over the stopper portion 57, passes through the opening portion 57 a, and is pushed into the second storage portion 14 against the elasticity of the spring 56. The push plate 32 is stopped in the cassette 50 at the lowered position where it is pushed in, and waits at the lowered position until the next bill insertion. Therefore, the banknote 1 stored in the storage unit 14 is kept pressed by the push plate 32 until the next true banknote is inserted into the entrance 11. For this reason, even if the banknote 1 covered by the push plate 32 is intentionally pulled out in the storage section 14, it is practically impossible to take out the banknote 1 through the inlet 59.

When the banknotes 1 are accumulated in the cassette 50 of the banknote stacker 30 and become full, the banknote stacker 30 is removed from the frame 2. The cassette 50 of the removed bill stacker device 30 is closed by the door 52 and is in a locked state. Cylinder lock 6 by key operation
The door 52 is unlocked by removing the first lock lever 63 from the lock receiver 39. As described above, when the bill stacker device 30 is removed, the door 52 is locked and the pushing device 1 is locked.
5 is closed and sealed by the substrate 31. Therefore, illegal withdrawal of the banknotes stored in the storage unit 14 is impossible.

When the bill stacker device 30 is removed from the frame 2, the connection between the planetary gear 26b of the transport device 20 and the intermediate gear 44 on the pushing device 15 side is released, and the pushing device 15 pushes by the urging force of the spring 37. The plate 32 is returned to the return position.

[0023]

As described above, in the bill stacker according to the present invention, the driving device holds the push plate of the pushing device in the extended state except when the bill is supplied to the first storage portion through the inlet. Since the movement of the banknote from the second storage section to the first storage section is prevented, the banknote is constantly pressed by the link device and the push plate, so that unauthorized removal of the banknote can be prevented.
