を特徴とする光学的回転検出装置。[Claims for Utility Model Registration] A rotating body that has a high portion and a low portion along the rotation direction, and is formed of the same material so that the high portion and the low portion have the same light reflectance; a light emitting element arranged to project light toward a surface including the high portion and the low portion of the rotating body; and a light-receiving element arranged to detect the resulting reflected light, such that the output of the light-receiving element is different depending on when the light is projected onto the high area and when the light is projected onto the low area. An optical rotation detection device characterized in that distances between the light emitting element and the light receiving element with respect to the rotating body are set.
