Abstract

A programmable coin acceptor which is readily repro­ grammed to accept different coin sets is described. The ac­ ceptor includes a detector (10) which generates an alternating magnetic field through two spatially symmetric flux paths (23,25). Disposed in each of the flux paths (23,25) is a detector coil (22,26). When the acceptor is in use a coin is passed through one If the flux paths (23). The resulting difference in the flux through the two paths (23,25) induces a voltage ac­ ross the detector coils (22,26). The amplitude of this voltage and its phase relative to the excitation voltage are derived and compared with stored information to determine whether the coin should be accepted. The stored information may readily be changed for a new coin set by switching the accep­ tor to programming mode and passing selected coins from the coin set through the detector (10) in a predetermined manner.
