The present invention provides a coin arranging/conveying apparatus that is capable of reliably conveying coins one at a time into a coin passage unit even if there is such a great difference in diameter or thickness of coins. A first gate portion is defined by a separation roller, an arranging/conveying surface of an arranging/conveying belt, and a movable roller. The movable roller faces the underside of the arranging/conveying surface of the arranging/conveying belt. A second gate portion is defined by a coin passage upstream end roller, and the portion of a transfer belt wrapped around the coin passage upstream end roller. Coins are arranged in a single layer in single file by means of the first gate portion, as well as the second gate portion.
