CA 2209737

A validator portion (12) of a bill validator is disclosed comprising two different plastic materials of different colors, fused together. The first plastic material (70) is preferably opaque, or black, and the second plastic material (64) is preferably clear. The clear material is used to provide windows (62, 63) through the validator housings for light to pass from light sources, such as light emitting diodes (50), to photodetectors, such as phototransistors (56), and protects the light source and photodetectors from water, dirt and air. Prisms (82a, 82b) 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.

Élément de validation (12) destiné à un appareil de validation de billets de banque, comprenant deux matériaux de plastiques différents thermocollés, ayant des couleurs différentes. Le premier matériau plastique (70) est de préférence opaque ou noir et le second matériau plastique (64) est transparent. Le matériau transparent sert à faire des fenêtres (62, 63) dans les logements de l'élément de validation afin de permettre à la lumière, produite par des sources lumineuses telles que des diodes électroluminescentes (50) d'atteindre des photodétecteurs, tels que des phototransistors (56). Les fenêtres protègent aussi la source lumineuse et les photodétecteurs de l'eau, de la saleté et de l'air. La présente invention peut également comprendre des prismes (82a, 82b) pour la détection d'éléments étrangers, comme des fils. Conformément à un autre aspect de l'invention, l'élément de validation peut être fabriqué par un procédé de moulage par injection en deux étapes.
