ABSTRACT:
A coin discriminating apparatus for discriminating coins transported in a coin passage includes a magnetic sensor having oscillating inductors and receiving inductors, the receiving inductors being constituted by connecting a plurality of tip-like inductors disposed in a direction perpendicular to a longitudinal direction of the coin passage in series with each other, the respective tip-like inducers having capacities selected so that output levels thereof are equal with respect to magnetic flux density produced by supplying electrical current of high frequency into the oscillating inductors. According to the thus constituted coin discriminating apparatus, it is possible to discriminate coin acceptability and coin denomination at low cost and with high accuracy.
