検出装置。[Claims for Utility Model Registration] (1) A position detecting device for a rotating light comprising a light source and a reflecting mirror placed on a rotating plate and reflecting the light from the light source, the rotation center of the rotating plate being Marking parts are formed on opposite sides of the marking part, and each marking part is formed with a mark that has a significantly different reflectance from the other parts, and one marking part has a narrow circumferential width. A narrow mark is formed, and a wide mark whose circumferential width is at least three times the width of the narrow mark is formed on the other mark part, and a light emitting element and a light receiving element are provided at a position opposite to the above mark part. Position detection of a rotating light, characterized in that two reflective optical sensors are arranged spaced apart in the rotating direction of the rotary plate, and the spacing between the optical sensors is slightly larger than the width of the narrow mark. Device. (2) Claim 1 of the utility model registration, characterized in that a portion of the rotary plate that rotates facing the optical sensor and has a high reflectance protrudes in the direction in which the optical sensor is arranged. The position detection device for the rotating light described above.
