ABSTRACT:
A validator portion of a bill validator is disclosed comprising two different plastic materials of different colors, fused together. The first plastic material is preferably opaque, or black, and the second plastic material is preferably clear. The clear material is used to provide windows through the validator housings for light to pass from light sources, such as light emitting diodes, to photodetectors, such as phototransistors, and protects the light source and photodetectors from water, dirt and air. Prisms can be provided as well, to provide a detector for foreign matter such as string. In accordance with another aspect of the invention, the validator can be formed by a two shot, injection molding process.
