ABSTRACT:
A solid state, coin activated mechanism comprises a rejector for improper coins or slugs and the like, and the rejector includes a coin infeed chute with a LED or the like and a light sensitive device positioned at one side of the chute pointing angularly toward one another and toward the path of advancement of a coin in the chute, such that a bona fide coin with an irregular surface will intercept the light from the LED and the like and reflect the light to the light sensitive device, which in turn energizes a gate mechanism associated with the chute to pass a bona fide coin and to reject coins or slugs and the like which do not have the proper reflectivity and irregular surface. In one form of the invention, the chute includes a side wall inclined to the vertical and an inclined track along a bottom edge thereof along which coins roll when fed to the rejector. A stop surface is at an upper edge of the side wall and openings are formed through the side wall, to halt progression through the mechanism of coins and the like which are not of a predetermined size. In another form of the invention, a plurality of LEDs or the like, and a corresponding number of operatively associated light sensitive devices are disposed on respective opposite sides of the chute, at different distances from the track and spaced apart axially along the chute, to detect coins of different size rolling along the track and effect actuation of other devices in the mchanism to pass bona fide coins and to reject improper coins and slugs and the like.
