とする複写機の光学系ユニツトの位置検出装置。[Scope of Claim for Utility Model Registration] A copying machine that exposes and scans a document by moving an optical system unit comprising a light source lamp and a reflection plate that condenses light from the light source lamp in parallel to the surface of the document. In the position detection device for an optical system unit, an aperture is formed in the reflecting plate, and an optical sensor is attached to the optical system unit to receive light rays leaking from the light source lamp through the aperture when the optical system unit comes to a predetermined position. A position detection device for an optical system unit of a copying machine, characterized in that it is installed outside a moving area.
