ABSTRACT:
An apparatus for electronically discriminating coin diameter includes a vertical or inclined coin passage defined by a pair of opposed side plates and a pair of opposed edge plates. A pair of proximity switches are opposedly arranged at the opposed edge plate sides and spaced from each other by a distance corresponding to the diameter of a genuine coin to be discriminating, and an electronic circuit is arranged such that when both of the proximity switches are simultanuously turned ON by a coin passing through the coin passage, a genuine coin diameter signal is output.
