した光学式角度検出器。 In an optical angle detector that detects the rotation angle of an object to be detected, by irradiating it with light, the irradiated point can be detected as two-dimensional coordinate values2.
A dimensional optical position detection element is disposed perpendicularly to the axis of a rotating shaft that rotates integrally with the object to be detected, and a light source and a rotary plate having a light-transmitting hole are arranged so that the center point of the light-transmitting hole is located at a predetermined position. The rotation angle of the object to be detected is detected by irradiating light emitted from a light source onto the two-dimensional optical position detection element through the transparent hole. Optical angle detector.
