<p>A mechanical coin checker is proposed having a coin channel which has a running rail for the coin to run down, in or at which channel checking arrangements are provided to check the properties of the coins, having a coin acceptance shaft and a return shaft, disposed below the running rail, to return coins which are not accepted. The running rail has in the running direction of the coin a recess into which coins which are too thin slide and possibly fall into the return shaft. In front of the coin acceptance shaft is disposed a detent pawl, which is rotatably mounted at a flap forming a part of the coin channel. A detent wire, which is pivotable about a portion of its longitudinal axis, co-operates with its one end region with the detent pawl and is disposed with its other end region below the recess, in such a way that when a coin slips through the recess, the detent wire pivots and takes the detent pawl with it into the coin channel to engage at least one integrally formed arm.</p> |
