Abstract
An optical rotary encoder eliminates the necessity of relatively positioning a code plate and a click mechanism therefor so that it can be assembled with ease. The code plate is mounted for rotation relative to a stationary plate member, and the click mechanism including a ball and a spring plate is interposed between the code plate and the plate member so that all the members can be incorporated as a single device.
