The above process is repeated until the count end command is input from the input unit 625 or the bad coin discharge command, the deposit command or the return command is input (S1429).

When a bad coin discharge command is input from the input unit 625 (S1411), the controller 610 controls the electron cylinder driving unit 660 to drive the electron cylinder 15 to push the hopper 11 outward to the hopper 11. The coin stored in the discharge to the first bad coin moving passage 41.

On the other hand, when a deposit command is input from the input unit 625 (S1412), the controller 610 controls the third motor driver 650 to rotate the third motor forward to deposit coins accumulated in the coin sorter 51. Discharge.

However, when a return command is input from the input unit 625 (S1413), the controller 610 controls the third motor driver 650 to reversely rotate the third motor to return coins accumulated in the coin sorter 51 to the outside. To discharge.

When the above-described second solenoid is provided, the controller 610 may count time and drive the second solenoid by controlling the second solenoid driver 680 at predetermined time intervals.

In FIG. 14, when a bad coin discharge command is input from the input unit 625, the electronic cylinder 15 is driven to push the hopper 11 backward to remove the defective coins and foreign substances remaining in the hopper 11. Hereinafter, a method of automatically removing defective coins and foreign substances remaining in the hopper 11 will be described.

FIG. 15 is a flowchart illustrating a method of removing a defective coin and foreign material from the hopper 11 according to another embodiment of the present invention. FIG. 16 is a view illustrating a case in which the hopper 11 is pushed backward according to the operation of FIG. 15. It is shown.

First, when the counting starts (S1511), the controller 610 drives the first motor 141 and the second motor 31 through the first motor driver 630 and the second motor driver 640 (S1513). .

When the first motor 141 and the second motor 31 are driven, the controller 610 checks whether image data about coins is input from the CCD camera 21 through the image processor 690 (S1515).

In this case, when the coin image data is input, the general coin counting routine of S1410, S1414 to S1429 of FIG. 14 is performed (S1531).

On the other hand, if the coin image data is not input for a predetermined time (S1517), the controller 610 drives the electron cylinder 15 through the electron cylinder drive unit 660 to push the hopper 11 backward as shown in FIG. A space 113 is formed between the coin loader 13 and the coin loader 13 to drop the defective coin and foreign matter remaining in the hopper 11 to the first defective coin moving passage 41 (S1517). At this time, it is preferable that the first motor 141 is continuously driven so as to keep the poor coins and foreign substances remaining in the hopper 11 well, and the second motor 31 may be continuously driven or turned off. At this time, the reciprocating motion of the electron cylinder 15 may be such that bad coins and foreign matter fall better.

After the removal of the defective coin and foreign matter (S1517), the controller 610 turns off the electron cylinder 15, the first motor 141, and the second motor 31 (S1519).
