ABSTRACT OF THE DISCLOSURE The invention provides a multiple coin detecting apparatus for use in coin-operated machines for discrimin- ating between denominations of coins and genuiness of coins, so as to exclude from operation of the machines any coins which have not been specifically selected for acceptance. Essentially, the apparatus consists of a coin receiving and guiding free-fall chute of insulating material having a hollow core for receiving coins. An instantaneous analysis is made of the material of the coin near the entry of the chute and the apparatus im- mediately directs predetermined acceptable coins to an acceptance slot, and all other unacceptable coins are directed to the rejection slot. The analysis is made by a coil which surrounds the hollow chute and comprises a primary coil and a secondary coil. The secondary coil has windings protruding a specified distance over the edges of the primary coil and at a predetermined angle in relation to the windings of the primary coil, and provides a secondary coil voltage fluctuation in con- junction with the primary coil voltage fluctuation, to give separate indications of the exact metal contents of the coins being evaluated. These two independent voltages are each connected to a chain of comparator gates whose outputs are subsequently rendered high in direct proportion to the magnitude of voltage appearing at their input, forming a direct analog to a digital converter. Selective acceptance of each coin is therefore possible by decoding its exclusive digital code.
