US 5,632,367 A · Validation housing for a bill validator made by a two shot molding process

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 photo-transistors, 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.

Dependent claims

A validation portion of a bill validator comprising:

a first plastic housing having a first portion of a first plastic material and a second portion of a second plastic material, wherein the first and second plastic materials are fused, the second plastic material defining at least one window through the first housing, the window having first and second sides;
the first housing comprising a first surface defining, at least in part, a path for a bill through the validation portion, a second surface on the opposite side of the housing from the first surface, wherein the first surface of the first housing is aligned with the first side of the window and the second surface of the first housing is aligned with the second side of the window;
and
a first light source adjacent the second side of the window for emitting light through the window to interact with a bill in the bill path, wherein the second plastic material is transparent to at least the light emitted by the light source.

1 more element

A bill validator comprising a validation portion comprising:

first and second integral plastic housings having a first portion of an opaque plastic material and a second portion of a clear plastic material, wherein the first and second plastic materials are fused;
the first and second housings having corresponding first surfaces defining, at least in part, a path for a bill through the validation portion, each housing having second surfaces on the opposite sides of each housing from the first surfaces;
the first housing further comprising at least one light emitting diode adjacent the second surface for examining the bill, the clear plastic material forming at least one window through the housing for light from the light emitting diode to pass through the housing into the bill path.
