Abstract

What is proposed is an apparatus for checking coins or similar metal discs, in which the coin in the coin channel can be moved through at least one periodically changing magnetic field which is generated by a pulse generator connected to at least one coil, the coin causing, on a sensor designed as a coil, a signal change which is fed to an evaluation circuit. At least one exciting coil is located on one side of the coin channel and at least one measuring coil is located on the other side, these coils being assigned to one another. The measuring coil is coupled to the generator (9) by means of at least one coupling member (11). <IMAGE>
