ABSTRACT:
Two sensors (2, 3) are placed opposite each other against the rim of the coin (5). By this, a signal, corresponding to the diameter of the coin (5) is produced and a drive (18/19, 23/24) is driven which moves two support members in order to support a coin between them (13), the diameter of which corresponds to the distance between the sensors (2, 3) in a position that is centered to a test coil (10) of an inductive coin testing device.
