ABSTRACT:
An optical encoder assembly includes an integral flexible coupler. A flange extending from the flexible coupler serves as a bearing retainer to hold a disc table and unitary bearing shaft in fixed axial position relative to the bearing. The bearing is further axially fixed relative to a stationary base which supports encoder disc illuminating and detecting optics. In a preferred form, the flexible coupler extends through the center of the encoder assembly, and a dust tube is positioned between the coupler and the encoder optics.
