Abstract
An optically transmissive armature is presented for use with an optical encoder mechanism in a cursor control device. The armature includes a substantially planar rectangular base, a plurality of supports, and a plurality of optical wave guides. An encoder mechanism is rotatably secured to the supports by an axis and is disposed in a predetermined position between the wave guides. The guides provide an optical pathway between photo-emitter/photo-detector pairs mounted on the surface of the printed circuit board of the cursor control device.
