PROBLEM TO BE SOLVED: To improve the problems that in the conventional coin cleaning and separation case, coins are separated and stored when flowing in a fixed direction, that is, in a direction from a big separation hole to a smaller one, but cannot be separated again when passing the separation holes in the reverse direction from the small separation hole to the bigger one, and further that cleaning efficiency is lowered when a cleaning solution used for cleaning the coins is a liquid detergent. SOLUTION: After a coin is separated and stored when moving in the direction from a big separation hole to a smaller one, the separation and storage state once generated is kept by installing a check valve preventing the coin from passing the separation holes even when the coin moves in the reverse direction from the small separation hole to the bigger one. Further, cleaning efficiency is improved using not only a liquid detergent but a solid and a gas one. COPYRIGHT: (C)2009,JPO&INPIT
