ABSTRACT:
A coin acceptor includes first and second members initially spaced apart from one another and frictionally carrying a third member. Moving the first and second members toward one another displaces the third member a distance corresponding to the weight of the coin selectively positioned on the third member. The distance which the third member is displaced is compared with a reference position.
