In the coin processing device 100 configured as described above, the operation of the entire device is controlled by a control unit (not shown) and a control unit as a calculation unit based on a control program (software) stored in a storage unit such as a memory (not shown). .
The operation of the above-described configuration will be described based on the explanatory diagram of the coin conveying operation in the embodiment of FIGS. The operations of the following units are controlled by the control unit.

  When coins are input into the coin insertion slot 2 in a lump, the coins are accumulated on the rotating disk 3. The rotary disk 3 rotates in the direction indicated by the arrow A in FIG. 1 by driving the feeding motor 5, pushes out the accumulated coins by centrifugal force, and the pushed-out coins serve as openings of the disk guide member 7. Are ejected one by one from the discharge opening 8 to the coin passage 9.

  The coin pushed out to the coin passage 9 stays in the coin passage 9 as it is when the transport roller 10 is not rotating. When the transport roller 10 is rotated by driving the transport motor 11, it is pinched between the roller pair and the transport disk unit 13 It is conveyed to.

  The conveyance disk 16 of the conveyance disk unit 13 is rotated by the drive of the disk rotation motor 19, but changes in the output signal of the position detection sensor 22 by the light shielding member 23 (for example, detection of a through hole (slit) of the light shielding member 23). As a trigger, the coin receiving portion 17 is temporarily stopped at a position facing the coin passage 9.

  At this time, when the coins sandwiched between the transport rollers 10 are detected by the pre-feed sensor 28, the coin receiving portion 17 detected by the position detection sensor 22 faces the coin passage 9 and the coin passage 9 and the coin receiving portion 17. And the transporting roller 10 is rotated by driving the transporting motor 11 while the transporting disk 16 is stopped such that the transporting disk 16 is stopped so as to be in a positional relationship (that is, a position where coins can be received in the coin receiving unit 17). The clamped coin is conveyed to the coin receiving portion 17. In addition, since the conveyance guide bottom face 15 is arrange | positioned lower than the coin channel | path 9, a coin is smoothly delivered to the coin receiving part 17, without being caught.

  The rotation of the transport disk 16 is stopped until a predetermined time elapses after the coin is transported into the coin receiving portion 17 and detected by the feeding sensor 24, and the delivery of the coin to the coin receiving portion 17 is completed.

  When a predetermined time has elapsed, the transport disk 16 that has been stopped is rotated again, and the coin receiving portion 17 is moved to a position facing the coin passage 9 and stopped. Since the through holes (slits) of the light shielding member 23 are formed at equal intervals, the transport disk 16 is repeatedly rotated and stopped at regular time intervals. Accordingly, the coins transferred to the coin receiving portion 17 of the transport disk 16 are repeatedly transported (hereinafter referred to as “intermittent transport”) by repeatedly rotating and stopping the rotation at regular time intervals.

  By repeating the above operation, the coins inserted into the coin insertion slot 2 are sequentially conveyed into the coin receiving portion 17 of the conveying disk 16. When the coin is detected by the pre-feed sensor 28, the coin receiving portion 17 is not opposed to the coin passage 9 by the position detecting sensor 22 (the coin passage 9 and the coin receiving portion 17 are not in a positional relationship). ) Is detected, the position where the next coin receiving portion 17 faces the coin passage 9 and the coin passage 9 and the coin receiving portion 17 are connected while the conveying roller 10 holding the coin is stopped is stopped. Wait until
