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.
