ABSTRACT:
A coin identification apparatus includes a pair of spaced series connected elongated, planar coils driven by an oscillator. Maximum frequency and amplitude values of the oscillator output generated by the passage of a coin between the pair of coils are compared with prestored frequency and amplitude values of acceptable coins. A processor, upon detecting a match between the detected and pre-stored frequency and amplitude values, activates a motor to rotate a coin receptacle to a position discharging coins into a storage receptacle and simultaneously causing a door latch pin to separate from a door latch allowing opening of the door to permit vending of an article from the enclosure in which the coin identification apparatus is mounted.
