ーム走査装置。[Claim for Utility Model Registration] A light beam that is deflected by a rotating polygon mirror through a transparent window provided in a part of a dust-proof housing and scans the surface of a photoreceptor or a document for exposure or reading. The scanning device includes: a reflecting mirror having a light beam transmission region without a reflective coating on at least one side of a region that reflects the scanning light beam; and a light beam transmitted through the light beam transmission region being detected outside the housing. 1. A light beam scanning device comprising a detection means for detecting the position of a light beam.
