ABSTRACT:
An electronically controlled coin tester which generates an audio frequency response in a coin to be tested, then electronically analyzes the response to determine if it matches the characteristic response of an acceptable coin. The audio frequency response is generated by a striker which mechanically impacts the coin as it traverses the coin chute. The striker may be deflectable so that it is deflected from the path of coin travel after it performs its function. Gating is provided to enable the detector circuitry only in the presence of a coin, thereby reducing the susceptibility to tampering. Signal processing circuitry, which can store a plurality of responses relating to a plurality of acceptable coins, makes a comparison with a sampled characteristic to determine if the tested coin is acceptable or should be rejected.
