<Configuration and operation of power transmission mechanism>
Next, the configuration and operation of a part of the power transmission mechanism provided in the banknote transaction apparatus according to the present invention will be described.

  7A, 7B, 7C, 7D, and 7E are explanatory views showing the operation of the driving member and the connection state between the driven member.

  The power transmission mechanism in the present embodiment includes a driving member 500, a left driven member 503a on the left side of the driving member, a right driven member 505a on the right side of the driving member, and a shaft 503S. Here, when the distance between the left driven member 503a and the right driven member 505a is L1, and the length of the drive member 500 is L2, the relationship is L1 <L2.

  The drive member 500 can freely rotate and move with respect to the shaft 503S, and the drive member 500 includes a left contact portion 500l having a slope and a right contact portion 500r. Further, the drive member 500 is provided with a long hole 515 in a direction inclined with respect to the shaft 503S, and the shaft 503S is provided with a pin 518p fixed to the shaft 503S so as to penetrate the long hole 515. Yes.

  A coil spring 516 is attached to the drive member 500. Here, the coil spring 516 will be described in detail with reference to FIG. 7E. The coil spring 516 applies a resistance force in a direction opposite to the rotation direction of the drive member 500 in a state where the coil spring 516 is not fixed to the drive member 500. The end 516a of the coil spring 516 is inserted into the hole 530a of the fixed regulating member 530. When the driving member 500 moves in the thrust direction indicated by the arrow X, the end 516a of the coil spring 516 slides on the regulating member 530 and moves in the same direction as the arrow X direction. The coil spring 516 is an example of the resistance member of the present invention.

  Further, the left driven member 503a and the right driven member 505a are attached to the shaft 503S so as to be rotatable through the bearings 503c and 505b. The left driven member 503a and the right driven member 505a have a claw portion 5031 of the left driven member having a slope and a claw portion 5051 of the right driven member, respectively.

  Note that both the contact surfaces of the driving member and the driven member need not be inclined surfaces. For example, you may provide a slope only in the left-right contact part of a drive member. Or you may provide a slope only in the nail | claw part of a driven member.

  Next, with reference to FIG. 7A-FIG. 7D, the operation | movement of a drive member and the connection state of a driven member are demonstrated.

As shown in FIG. 7B, when the shaft 503S rotates in the direction of the arrow A, the driving member 500 receives an elastic resistance force from the coil spring 516, so that a contact force F1 is generated between the pin 518p and the elongated hole 515, The power of the shaft 503S is transmitted to the drive member 500. Further, with the rotation of the shaft 503s, right contact portion 500r of the drive member 500 receives the contact force F2 from the inclined surface of the claw portion 5051 of the right driven member that the contact, the drive member 500 is an arrow _{D 1} direction Extruded.

The axial direction of the contact force F1 and F2 as described above, the drive member 500 is reliably moves to the left driven member 503a in the arrow _{D 1} direction (FIG. 7B). Then, the left contact portion 500l of the driving member 500 comes into contact with and is coupled to the left driven member 503a (FIG. 7C), and the power of the shaft 503S is transmitted to the left driven member 503a through the driving member 500. At this time, the driving member 500 moves to the opposite side of the other right driven member 505a, and the driving member 500 and the right driven member 505a are not in contact with each other, so that no rotational torque is transmitted to the right driven member 505a (FIG. 7D). .

  As described above, when the distance between the left driven member 503a and the right driven member 505a is L1, and the length of the drive member 500 is L2, the relationship is L1 <L2. When the lengths of L1 and L2 have such a relationship, for example, even when the contact between the coil spring 516 and the drive member 500 becomes insufficient and the contact force F1 becomes very small, the right contact portion 500r of the drive member 500 is obtained. The driving member 500 can be coupled to the left driven member 503a only by the contact force F2 between the right driven member and the inclined surface of the claw portion 5051 of the right driven member.

  8A to 8D are explanatory views showing the operation of the driving member and the connection state between the driven member in the direction opposite to that of FIGS. 7A to 7D described above. When the shaft 503S rotates in the direction of the arrow B, the driving member 500 receives an elastic resistance force from the coil spring 516. Therefore, a contact force F3 is generated between the pin 518p and the elongated hole 515, and the power of the shaft 503S is driven. 500.

Further, with the rotation of the shaft 503s, the left contact portion 500l of the drive member 500 receives the contact force F4 from the slope of the claw portion 5031 of the left driven member that the contact, the drive member 500 is indicated by the arrow _{D 2} Extruded in the direction.

The axial direction of the contact force F3 and F4 described above, the drive member 500 is reliably moved to the right driven member 505a in the arrow _{D 2} direction (FIG. 8B). Then, the right contact portion 500r of the driving member 500 contacts and is coupled to the right driven member 505a (FIG. 8C), and the power of the shaft 503S is transmitted to the right driven member 505a through the driving member 500. At this time, the driving member 500 moves to the opposite side of the other left driven member 503a, and the driving member 500 and the left driven member 503a are not in contact with each other, so that no rotational torque is transmitted to the left driven member 503a (FIG. 8D). .

  Next, the case where the above-described power transmission mechanism is applied to a second temporary storage 50 that is a banknote storage for storing and discharging banknotes will be described. With reference to FIG.9 and FIG.10, the detailed structure of the 2nd temporary storage 50 of this Embodiment is demonstrated.

  FIG. 9 is a side view showing the configuration of the second temporary storage 50. The second temporary storage 50 includes a tape 501, a scraper 510 for peeling the tape 501 and banknotes, an idler 504 arranged for adjusting the arrangement and tension of the tape, and a banknote P on the tape 501.

The second temporary storage 50 is provided with one long tape 501, and a wheel 502 and a reel 503 are provided at both ends of the tape. Note that a rotational driving force is applied to the wheel 502 and the reel 503 by a driving motor 508.

  When banknotes are stored in the second temporary storage 50, the banknotes pass between the rollers 511 from the transport path 24 and are transported onto the movable guide 506, and are deformed into a waveform by the wheel 502 and the guide roller 509. Then, it is conveyed onto the tape 501. Then, by rotating the wheel 502, the banknote is conveyed by the tape 501, and the banknote is wound around the wheel 502 together with the tape 501.

  On the other hand, when the banknote is released from the second temporary storage 50, the reel 503 takes up the tape 501 and the banknote wound around the wheel 502 together with the tape 501 is released from the wheel 502. At this time, the banknote sandwiched between the tapes 501 is deformed and imparted to a waveform by the wheel 502 and the guide roller 509, is discharged from the second temporary storage 50, and is transported to the transport path 24.

  Here, the scraper 510 is in contact with the wheel 502 at a predetermined pressure. The banknote is wound around the wheel 502 and discharged along the outer periphery of the wheel 502. In such a case, if the roller 511 cannot receive the banknote released from the wheel 502, it causes a paper jam.

  In order to prevent such a banknote conveyance jam, the scraper 510 peels the banknote released along the outer periphery of the wheel 502 from the outer periphery of the wheel 502 and guides it in the direction of the roller 511. Thereafter, the banknote is separated from the tape 501 by the roller 511 and delivered to the transport path 24. The tape 501 passes through the idler 504 and is wound around the reel 503.

  FIG. 10 is a front view showing the configuration of the second temporary storage 50 according to the present embodiment. The shaft 502S and the shaft 503S are rotatably supported with respect to the side plate 513a and the side plate 513b.

The torque limiter 517 is connected to the reel 503 via the wheel 502 and the torque limiter 514 via the gear 503b and the gear 507. .

  A gear 512, a gear 503b and a gear 505, a reel 503, a driving member 500, and a left driven member 503a and a right driven member 505a are attached to both sides of the shaft 503S. The gear 512 is directly attached to the shaft 503S while being fixed to the shaft 503S, and a driving force is transmitted from the gear 520 of the driving motor 508.

  On the other hand, the gear 503b, the gear 505, the reel 503, the left driven member 503a, and the right driven member 505a are rotatably attached to the shaft 503S through the bearing 503c and the bearing 505b. The drive member 500 is attached so as to be rotatable with respect to the shaft 503S and movable in the axial direction (left-right direction in FIG. 10). Then, when the driving member 500 contacts the left driven member 503a or the right driven member 505a, the driving force is transmitted to the left driven member 503a or the right driven member 505a.

  A wheel 502 and a gear 519 are attached to the shaft 502S while being fixed to the shaft 502S.

  The operation of the second temporary storage 50 will be described with reference to FIGS. 11 and 12.

  FIGS. 11 and 12 are explanatory diagrams for explaining a drive system when the tape 501 is wound around the reel 503 of the second temporary storage 50. Here, since the operation of the power transmission mechanism including the drive member 500, the left driven member 503a, and the right driven member 505a is the same as the above, detailed description thereof is omitted.

  As shown in FIG. 11, when the drive motor 508 rotates, the driving force of the drive motor 508 is transmitted to the shaft 503S via the gear 520 and the gear 512 of the drive motor 508, and the shaft 503S is moved in the direction of the arrow A. Rotate.

  As described above, when the shaft 503S rotates in the direction of the arrow A, the driving member 500 receives an elastic resistance force from the coil spring 516, so that a contact force is generated between the pin 518p and the elongated hole 515, and the shaft 503S The power is transmitted to the drive member 500, and the drive member 500 moves to the left driven member 503a side.

  When the pin 518p moves to the end of the long hole 515, the left contact portion 500l of the driving member 500 is in contact with and coupled to the left driven member 503a, so that the rotational torque of the driving member 500 is transmitted to the left driven member 503a. . At this time, the driving member 500 moves to the opposite side of the other right driven member 505a, and the driving member 500 and the right driven member 505a are not in contact with each other, so that no rotational torque is transmitted to the right driven member 505a.

  With the above operation, the rotational torque of the left driven member 503a is transmitted to the reel 503, and the reel 503 rotates in the direction of winding the tape 501 (the direction of arrow C). When the reel 503 starts to wind the tape 501, tension is applied to the tape 501, so that a rotational torque starts to act on the wheel 502.

  When this rotational torque exceeds the set torque of the torque limiter 517, the wheel 502 starts to rotate in the direction in which the tape 501 is released (direction of arrow E). By the action of the torque limiter 517, the tape 501 can stably convey the banknote without loosening.

  Thereafter, after the completion of winding of the tape 501 by the reel 503 is detected by a sensor or the like (not shown), the drive motor 508 is stopped. When the drive motor 508 is stopped, the operations of the shaft 503S and the reel 503 are also stopped. At this time, the tension applied to the tape 501 is lost, and the operations of the shaft 502S and the wheel 502 are also stopped.

  FIG. 13 and FIG. 14 are explanatory diagrams of the drive system when winding the tape 501 and the banknote on the wheel 502 of the second temporary storage 50. Here, since the operation of the power transmission mechanism including the drive member 500, the left driven member 503a, and the right driven member 505a is the same as the above, detailed description thereof is omitted.

  As shown in FIG. 13, when the drive motor 508 rotates, the driving force of the drive motor 508 is transmitted to the shaft 503S via the gear 520 and the gear 512 of the drive motor 508, and the shaft 503S rotates in the direction of arrow B. To do. Here, as shown in FIGS. 11 and 12, when the driving member 500 winds the tape 501 around the reel 503 of the second temporary storage 50, it moves to the right driven member 505a side according to the same principle as described above. Then, the right contact portion 500r of the driving member 500 contacts the right driven member 505a.

  The rotational torque of the driving member 500 is transmitted to the right driven member 505a by the frictional force. At this time, since the drive member 500 moves to the opposite side to the left driven member 503a, the rotational torque is not transmitted to the left driven member 503a.

  The rotational torque of the right driven member 505a is transmitted to the shaft 502S via the gear 505 and the gear 519. The shaft 502S rotates in the direction in which the wheel 502 winds up the tape 501 (the direction of the arrow G). When the wheel 502 starts to wind the tape 501, tension is applied to the tape 501, so that rotational torque starts to be applied to the reel 503. This rotational torque is transmitted to the torque limiter 514 via the gears 503b and 507.

  When the transmitted rotational torque exceeds the set torque of the torque limiter 514, the reel 503 starts to rotate in the direction in which the tape 501 is ejected (direction of arrow F). By the action of the torque limiter 514, the tape 501 can stably convey the banknote without loosening.

  And after winding of a banknote is complete | finished, the drive motor 508 is stopped. When the drive motor 508 is stopped, the operations of the shaft 502S and the wheel 502 are also stopped. At this time, the tension applied to the tape 501 is lost, and the operations of the shaft 503S and the reel 503 are also stopped.

  As described above, according to the present embodiment, a part of the power transmission mechanism in the banknote transaction apparatus 101 has the drive member 500 and the driven member (the left driven member 503a and the right driven member 505a) for transmitting power on the same axis. When the drive member 500 is provided with driven members (left driven member 503a, right driven member 505a) on both sides of the drive member 500 and the drive member 500 transmits power to one driven member, the other driven member is provided. It has a structure that does not contact the member.

  Further, the driving member 500 includes an elongated hole 515 provided in an inclined direction with respect to the rotation axis (axis 503S), and a pin 518p fixed to the rotation axis (axis 503S) so as to penetrate the elongated hole 515. And the pin 518p is configured to move the drive member 500 in the axial direction of the rotation shaft (shaft 503S) by the elongated hole 515. Further, the coil spring 516 that can move in the same direction as the drive member 500 makes it possible for the drive member 500 to move reliably by the rotation of the shaft without causing a resistance force in the thrust direction to act on the drive member 500. Reliable power transmission is possible.
