Abstract
A coin handling system comprising an improved coin chute (115) for guiding coins in a coin operated machine is provided comprising a first chute piece (122) and a second chute piece (123), each forming an opposite sidewall of the chute (115). An internal bevelled surface (129) is formed on the backwall (140) of one of the chute pieces (122, 123) so that foreign objects forced into the chute (115) and impacting the backwall (140) will cause the chute (115) to separate into the chute pieces (122, 123) and thereby cause the foreign object to leave the chute (115). Additionally, external bevelled surfaces (144, 148) are formed on the chute pieces (122,123) so that if a foreign object impacts the outside of the chute (115), the chute (115) separates into the chute pieces (122, 123) and allows continued movement of the foreign object. Thus, the foreign object does not become caught in the coin chute (115). In another aspect of the invention, ridges ( 130) are formed on the backwall (140) of the chute (115). These ridges (130) obstruct and inhibit downward movement of foreign objects that have been forced into the chute (115) and that impact the backwall (140).
