  The configuration of one discharge processing unit 7a has been described above, but the other discharge processing units 7b... Are configured similarly to the above-described discharge processing unit 7a. Therefore, when manufacturing the discharge processing mechanism 3 in the coin payout device 1 according to the present embodiment, the discharge processing units 7a...

  On the other hand, FIG. 6 shows an electric block circuit. Reference numeral 27 denotes a controller provided in the discharge processing mechanism 3. The drive motor 6 described above is connected to the output side, and the solenoids 14 provided in each discharge processing unit 7 a. Further, detection switches 61 are connected to the input side of the controller 27 to detect that the coins Ca are normally ejected from the coin stackers 2a. Further, 62 is a display unit connected to the controller 27. The display unit 62 displays an error when at least the coins Ca ... are not normally ejected. In addition, various displays such as a payout amount can be performed as necessary. On the other hand, 71 is a teller machine installed at a bank window or the like, and the coin payout device 1 (controller 27) is connected to the teller machine 71 for use. As a result, when the controller 27 receives the command information Dx related to the type and number of coins to be paid out from the Terras machine 71, the controller 27 operates the drive motor 6 and the solenoid 14... And the coin Ca corresponding to the command information Dx. The sequence control to discharge is performed.

  Next, the operation of the coin payout device 1 according to the present embodiment will be described according to the flowchart shown in FIG. 7 with reference to FIGS.

  First, when payment is made to a customer at a bank counter or the like, command information Dx related to the type and number of coins (coins) to be paid out is transmitted from the Terras machine 71 to the controller 27 of the coin payout device 1 (step) S1). The controller 27 operates the drive motor 6 by receiving the command information Dx (step S2). Thereby, the rotating shaft 5 is decelerated by the worm gear 41 and the driven gear 42 and rotates. At this time, the rotation direction of the rotation shaft 5 is the Fr direction in FIG.

  If the drive motor 6 is activated, the nth solenoid 14 corresponding to the type of coin based on the command information Dx is turned on (step S3). When the solenoid 14 is OFF, as shown in FIG. 3, the plunger 14p protrudes upward and the engaging pin 58 is in the raised position, so that the switching lever 26 biased by the spring 59 is With the portion 57 as a fulcrum, it rotates counterclockwise in FIG. 3 and is displaced to the locking position Pf. As shown in FIG. 3, the switching lever 26 at the locking position Pf is locked to the clutch portion 24 from a direction opposite to the turning direction Fr of the clutch portion 24 to displace the clutch portion 24 to the cutoff position Pr. Thereby, the clutch mechanism part 12 will be in the interruption | blocking state, and since the latching of the lock part 23 and the clutch part 24 is cancelled | released, the lock part 23 will be in an idling state. Therefore, the coin discharging operation is not performed.

  On the other hand, when the solenoid 14 is turned on, as shown in FIG. 4, the plunger 14 p is pulled downward, and the engagement pin 58 is displaced to the lowered position, so that the switching lever 26 is biased by the spring 59. Against this, it is rotated clockwise in FIG. As a result, the switching lever 26 is displaced to the locking release position Pn that is separated from the clutch portion 24. As a result, the clutch portion 24 biased by the spring member 25 is displaced to the connection position Ps, and the clutch mechanism portion 12 is in a connected state (step S4). In this case, since the lock portion 23 rotates integrally with the rotary shaft 5, the clutch portion 24 is located at a position where the locking surface of the lock portion 23 is substantially parallel to the locked surface of the clutch portion 24. It is displaced to the connection position Ps, and the locked state is brought about when the locking surface of the lock portion 23 and the locked surface of the clutch portion 24 abut. The position of the clutch portion 24 at the connection position Ps is restricted by the stopper pin 24s. Thereby, the crank cam 22 rotates integrally with the rotating shaft 5.

  The rotation of the crank cam 22 causes the crank lever 21 engaged with the crank cam 22 to repeatedly rotate and displace within a fixed angle range with the support shaft portion 54 as a fulcrum. It is converted into a reciprocating forward / backward displacement of the push lever 10 via the shaft portion 55. That is, when the crank cam 22 rotates once, the push lever 10 is displaced from the retracted position shown in FIG. 3 to the advanced position shown in FIG. 4 and then returned to the retracted position shown in FIG. . At this time, when the push lever 10 moves forward, one coin Ca located at the bottom of each coin Ca (or Cb...) Stacked on the coin stacker portion 2a (or 2b. S5). Then, the pushed coin Ca is discharged from the discharge port 32 onto the coin tray 33.

  At this time, the detection switch 61 described above is disposed in the discharge passage through which the coin Ca discharged from the coin stacker unit 2a (or 2b...) Passes, and when the coin Ca is normally discharged, The detection switch 61 is turned on, and the detection result is given to the controller 27 (step S6). On the other hand, the controller 27 sets a monitoring time corresponding to the number of sheets to be discharged, and monitors whether or not the number of coins Ca based on the command information Dx is normally discharged within the monitoring time (steps S7 and S9). . At this time, if discharged normally, the nth solenoid 14 is turned OFF (steps S7 and S8). On the other hand, when the number of coins Ca based on the command information Dx is not normally discharged within the monitoring time, error processing is performed (steps S9 and S10). In this case, an error is displayed on the display unit 62.

  Further, when there are other types of coins Cb to be discharged, the corresponding solenoids 14 are turned on, and the same discharge process is sequentially performed (steps S11, S3,...). When the discharge process of all coins Ca ... based on the command information Dx is completed, the drive motor 6 is turned off (step S11). Normally, there are a plurality of types of coins Ca to be discharged, so that a plurality of discharge processing units 7a... Operate in one payout operation. In this case, as illustrated, the discharge processing units 7a... May be operated in order, or may be operated simultaneously by setting a plurality of processing systems of the controller 27.

  Although the best embodiment has been described in detail above, the present invention is not limited to such an embodiment, and the scope of the present invention is not deviated from the gist of the present invention in the detailed configuration, shape, material, quantity, and the like. It can be changed, added, or deleted arbitrarily. For example, not only coins but also various coins other than coins can be applied to the coins Ca. Moreover, although the example which uses the coin payout apparatus 1 connected to the Terrars machine 71 was given, it can be used for various other purposes and can be incorporated into various devices such as vending machines.
