る角度検出装置。 An angle detection device that detects the rotation angle of a rotating body includes an absolute code plate and an incremental code plate that are mounted on one rotating shaft at a constant interval, and an incremental or absolute code plate that reflects the light that has passed through the absolute code plate. A half mirror (beam splitter) that transmits light to the code plate,
The device includes a light receiving element that receives light reflected by the half mirror, a light receiving element that receives light transmitted by the half mirror, and two signal processing units that separately process signals from the two light receiving elements. Characteristic angle detection device.
