The coins put on the tray 15 are sequentially fed out one by one to the discriminating section 18 of the next stage via the feeder 17. After the coins guided to the discriminating unit 18 are discriminated here for authenticity and denomination, the coins are branched and conveyed to the lower temporary storage unit 20 side and the stacker 21 side via the individual conveying path 19. It is provided as follows. The individual transport path 19 individually transports the coins C interposed between the coin feed pins 22 arranged at a constant pitch in the transport direction one by one in a standing state, and individually transports the individually transported coins C. The sheets are dropped one by one from the terminal reversing section of the transport path 19 and temporarily stored in the temporary storage section 20 below. This temporary storage unit 20
Sets the upper surface of the temporary storage belt 23 as a storage unit, and forwardly transports the belt 23 to transfer the coin C guided to the upper surface of the temporary storage belt 23 to the lower collection safe 2.
4 to be stored. If the deposit is canceled at the time of the temporary storage, the temporary storage belt 23
Is transported in the reverse direction, dropped from the temporary storage unit 20 and guided on a return transport belt 25 below, and the guided coins are returned to the deposit / withdrawal port 13 via the belt 25. A replenishing chute 26 is connected to the intermediate position of the individual transport path 19, and coins C are replenished and supplied to the stacker 21 via the replenishing chute 26. It is dropped from the lower surface and guided to the lower return conveyor belt 25, from which it is returned to the cash slot 13. The above-mentioned stacker 21 arranges storage cylinders of denominations in parallel, and stores coins supplied here, for example, for 1 yen,
Coins which are individually stored in denominations such as 5, 10, 50, 100, and 500 yen, and coins fed out of the storage tube are received and transferred via the withdrawal transport belt 27 and the previously described return transport belt 25. It is configured to withdraw money to the cash slot 13. In addition, the collective replenishment conveyance belt 28 is provided from the collection safe 24 described above.
, The coins collected in the safe are fed to the return conveyor belt 25 described above, and the coins are appropriately replenished to the respective storage cylinders of the denominations via the deposit and withdrawal port 13 and the replenishment chute 26. ing. In the figure, 29 is a withdrawal discrimination unit, 30
Is a refill cartridge.

FIG. 2 shows a coin processor 1 with a return output adjusting function.
1 shows a control circuit block diagram, and a CPU 31
Each of the circuit devices is controlled according to the program stored in the RAM 2, and the control data is stored in the RAM 33 so as to be readable. By the way, when returning a large number of coins during the return processing of coins, the CPU 31 adjusts the transport output of the temporary storage belt 23 to a gentle transport output suitable for returning a large number of coins. When returning coins, the transport output of the temporary storage belt 23 is adjusted to a high-speed transport output suitable for returning a small number of coins, and a return process is provided with a variable speed transport function suitable for the amount of coins to be returned. Improving efficiency. Further, the CPU 31 controls and manages the processing state of the coins based on the detection signals of the coin detection sensors S1... Provided at each of the internal coin transport paths and at the positions where the coins are taken in and out. During the return process, the presence / absence of coins conveyed one by one on the return conveyor belt 25 is detected, and the temporary storage detection sensor S3 detects coins guided to the temporary storage unit 20. The monitoring timer T measures the light-shielding time of the return system detection sensor S2. Based on the light-shielding time, the CPU 31 determines the coin return processing state, and manages the drive output time of the temporary storage belt 23 in accordance with this. I do. The recovery drive motor M1 drives the temporary storage belt 23 so that it can be rotated forward and backward and at a variable speed, and continuously or intermittently drives the belt 23 based on a control signal of the CPU 31. The return drive motor M2 is connected to the return transport belt 2
5 is driven forward at a constant speed.

The return processing operation of the coin processing machine 11 with the return output adjusting function thus configured will be described with reference to the flowcharts of FIGS. Now, when coins are deposited into the deposit / withdrawal port 13, coins C... Are taken in one by one through the feeder 17 as shown by the solid line in FIG. If false coins are detected at this time, and false coins are detected at this time, as shown by broken lines in FIG. 1 , the false coins are returned to the deposit / withdrawal port 13 via the individual transport path 19 and the return transport belt 25 (step n1). ~ N2).
On the other hand, in the case of genuine coins, the number of received coins is counted, and the coins are temporarily stored in the temporary storage unit 20. After confirming that there is no signal of the cancellation of payment, the coins are collectively collected in the collection safe 24 ( Steps n3 to n8). However, when the deposit cancellation signal is input, when the number of deposits stored in the temporary storage unit 20 is small, for example, when the number is 20 or less,
Since there is no risk of coin clogging even at high speed conveyance, the temporary storage belt 23 is continuously rotated twice and guided to the return / transport belt 25 more quickly on the belt 23, and is returned to the deposit / withdrawal port 13 (step). n9 to n10). Further, when the number of deposits stored at the time of deposit cancellation is a medium amount of about 20 to 50, the coins to be returned are dispersed and transported from the temporary storage unit 20 to such an extent that coin clogging can be avoided. For example, the temporary storage belt 23 is intermittently rotated by ３ rotation, and is guided to the return transport belt 25 in three times while monitoring so that the temporary storage belt 23 is smoothly fed out by a constant amount. The coins are returned one by one to the cash slot 13 (steps n11 to n15). Furthermore, when the number of deposits stored at the time of deposit cancellation is a large amount of 50 or more,
Since the number of coins to be returned is considerably large, the coins to be returned are dispersed and transported to such an extent that coin clogging can be sufficiently avoided. This is done, for example, by intermittently rotating the temporary storage belt 23 by 1/5 rotation and monitoring it so that it is smoothly fed out by a constant amount.
The coins are guided to the return / transport belt 25, and coins are returned to the deposit / withdrawal port 13 one by one via the return / transport belt 25 (steps n16 to n19).

As described above, a large number of coins can be stably conveyed in a low-output conveyance state in which coins are prevented from being jammed, and a small number of coins can be conveyed relatively quickly and efficiently returned in a short time. It is possible to return coins at an optimal return transport speed according to the amount of coins to be returned, thereby improving return processing efficiency and shortening the return processing time.
