Abstract

The invention relates to a coin acceptor mechanism in which a coil (101) is wound on a former (102) having a central opening (104) of a shape corresponding to the outline of a coin (103) to be checked and mounted with the plane of the opening at an angle to the horizontal. The opening (104) has, towards its lower side, a cross member (106) located below the transverse center line of the coil (101) so that a coin (103b) can momentarily rest on the cross member with its plane in the plane of the coil and can then turn about the cross member under its own weight and pass edge-wise through the opening in the former. A coin guide (110) guides coins edge-wise in a generally vertical direction towards the lower side of the coil so that a coin emerging from the guide enters the part of the opening (107) in the former (102) on the side of the cross member (106) away from the diameter and then turns about the cross member into the plane of the coil, at which point an output signal dependent on the characteristics of the coin as a whole is obtained. A lever (112) is included for clearing jammed coins.
