Abstract
A coin slot for a mechanical coin-acceptor unit and a mechanical coin-acceptor unit having a coin slot aperture incorporated in a front plate, a coin slot chamber and a coin channel are proposed, the coin channel being offset relative to the coin slot aperture and the coin slot chamber having a shoulder behind the coin slot aperture in the insertion direction. The shoulder is configured so as to vibrate as a coin reflector or membrane in such a manner that an impacting inserted coin in the coin slot chamber is reflected by the shoulder elastically in the direction of the front plate and experiences, in the coin slot chamber, a renewed reversal of direction in the direction of the coin channel.
