PROBLEM TO BE SOLVED: To be excellent in durability and also to surely solve the problem of coins jam between an ejecting belt and a separation roller with an inexpensive configuration. SOLUTION: A driving side engaging part 26a and a driven side engaging part 27a which are provided in a power transmission system from a power source to a separation roller 19 and are respectively formed by a driving side coupling 26 and a driven side coupling 27 which are linked coaxially in a freely rotatable way are brought into contact with each other in a freely contactable and separable way on the rotational locus of the part 26a according to the rotational direction of power transmitted from the power source. Thus, when coins jam takes place at an arrangement part between a carrier belt and the roller 19 and the power transmitted from the power source is switched from positive rotation to reverse rotation, the power transmission to the roller 19 is delayed by only about one rotation from the power transmission to the carrier belt and only the carrier belt undergoes reverse rotation. Then, it is more excellent in durability than a one-way clutch and also surely solves coins jam with an inexpensive configuration.
