Abstract

A coin identification apparatus includes a pair of series connected coils driven by an oscillator. Frequency and/or amplitude characteristics of the oscillator output generated by the passage of a distinct token between the pair of coils are compared with prestored characteristics of acceptable tokens. A processor, upon detecting a match between the detected and pre-stored frequency and amplitude characteristics, activates a motor to rotate a coin receptacle to a coin return position discharging the token to the user, simultaneously causes a door latch pin to separate from a door latch allowing opening of the door to permit access to the interior of the enclosure in which the coin identification apparatus is mounted and selects a new total vend value from memory associated with a detected token.
