Rotate counterclockwise respectively. As a result, the first gear 11 attached to the rotary shaft 4a of the double-feed preventing roller 4 rotates clockwise. That is, the rotational force of the motor 5 is transmitted to the two-sheet feed preventing roller 4 by the roller power transmission mechanism 7.
The double-sheet feeding preventing roller 4 is rotated so that the peripheral surface of the double-sheet feeding preventing roller 4 facing the conveying surface 3a of the conveying belt 3 moves in a direction opposite to the moving direction of the conveying surface 3a of the conveying belt 3. To do. As a result, the coins that overlap each other are separated and sent out one by one.

Whenever coins are separated and sent out, the first timer 25 is reset each time. Then, when a predetermined time T1 has elapsed after all the inserted coins have been sent out, a timer-out signal is issued from the first timer 25 and the motor 5 stops.

On the other hand, when, for example, a plurality of coins mesh with each other between the conveying surface 3a of the conveying belt 3 and the peripheral surface of the two-sheet feeding preventing roller 4 to cause a coin jam, the motor 5 reverses. Then, as shown in FIG. 6, the gear 8 rotates counterclockwise. As a result, the intermediate gear 10 rotates clockwise and the gear 9 rotates counterclockwise.
