Abstract
An apparatus for detecting different kinds of coins for use in a coin handling machine includes a coin selecting groove and a cam actuating the coin selecting groove to select the width of the coin selecting groove. Coin kind setting switches are provided for setting the particular kind of coins to be handled in accordance with the material thereof. The coin kind setting switches are actuated by coin kind selecting cams operatively associated with the cam to set detection levels. A detection coil device is provided adjacent to the coin selecting groove and detects the passing coin to issue a level signal in accordance with the material of the coin. A control circuit includes a comparator for comparing the detection levels set by the coin kind setting switches with the level signal detected by the detection coil device to detect an abnormal coin.
