ABSTRACT:
In an optical scanning module, for reading indicia with portions of differing light reflectivity, having a light emitter assembly for emitting a light beam towards the indicia, and a detector for receiving light reflected back from the indicia and producing an electrical signal corresponding to the differing light reflectivity of the indicia, an optical scan module component is provided which includes two circuits on respective circuit boards which are angularly mounted, and preferably orthogonally mounted, to each other. The two circuit boards are electrically connected to each other so as to operate together to produce signals to drive the emitter assembly and to process the electrical signal produced by the detector. The first and second circuit boards each form at least a portion of a peripheral side of the scanning module and thus, defining a wall of a chamber having the light emitter assembly disposed therein, and wherein the scanning light beam moves relative to the first and the second circuit boards.
