Abstract:
A reflective optical encoder has a hub member mounted on a rotation shaft, and a circular scale plate fixed to the hub member by an adhesive and having, on a front surface thereof, a pattern composed of high reflection portions having a high light reflectance and low reflection portions having a low light reflectance. Further, a step is provided at an outer peripheral portion of the hub member, and an outer diameter of the scale plate is larger than an outer diameter at an outermost peripheral portion of an adhesive surface of the hub member in which the scale plate and the hub member are bonded.
