Description:

Abstract:

An optical reader assembly for accurately determining the angular position of a rotary worktable or the like regardless of the diameter of the worktable. The position of the optical reader is adjusted by a micrometer with movement of the micrometer stem translated to movement of the optical reader tangentially to the periphery of the worktable. To enable the assembly to be utilized with worktables of different diameters, adjustable cam means regulate the amount of movement of the optical reader occasioned by a predetermined movement of the micrometer stem.
