Abstract

1483192 Coin handling mechanisms MARS Inc 21 Nov 1974 [22 Nov 1973] 54319/73 Heading G4V Apparatus for sensing the arrival of a coin 24 in a coin handling mechanism and for producing an output signal when the coin is of an acceptable type of material comprises, transmitting means including a transmitting inductor 32 for generating an oscillating magnetic field having components of two substantially different frequencies, receiving means including a receiving inductor 34 disposed in the magnetic field produced by the transmitting means for detecting the amplitude of said components at the location of said receiving inductor, means for guiding a coin between the transmitting and receiving inductors so that a substantial portion of the magnetic energy received by the receiving inductor is transmitted through the coin, and means, receiving circuit 40, for comparing the amplitudes of the components detected by the receiving means with the corresponding amplitudes for coins of an acceptable type of material and for producing an output signal indicative of the arrival of a coin of an acceptable type of material when the detected amplitudes of both components correspond substantially to the amplitudes for a coin of an acceptable type of material. A coin enters the apparatus through coin entry 12 and falls on to coin track 20 between front and back plates 14 and 16. A coin start gate 22 halts the coin between inductors 32 and 34. If the coin is acceptable the gate is moved and optical sensors 50 switched on to carry out further checks on the coin. If the coin is unacceptable the coin can be rejected by a coin reject lever (not shown) which momentarily separates the front and back plates or gate 22 can be removed and the coin allowed to travel along the coin track until it contacts gate and is diverted to a reject shoot 56. The transmitting means comprises an inductor core wound with two coils, the coils being connected to respective oscillator circuits 36, 38, oscillating at the two different frequencies.
