光ビーム走査装置。[Claims for Utility Model Registration] (1) A light beam deflection device that deflects a light beam emitted from a light source, at least one lens that focuses the deflected light beam on a predetermined exposure surface of a photoreceptor, and a deflected light beam. In a light beam scanning device equipped with an exposure means in which a reflecting mirror or the like that changes the direction of the beam is accommodated in an optical frame in a predetermined relative relationship, the optical frame is centered around a rotation axis parallel to the rotation axis of the photoreceptor. A light beam scanning device comprising a fixing means for fixing the optical frame without subjecting the optical frame to deformation of the main frame of the device by enabling rotation at a predetermined angle. (2) Utility model registration claim 1, characterized in that the parallel rotation axes are located on or near the optical axis of the light beam reflected by the reflecting mirror.
The optical beam scanning device described in 2. (3) The light beam scanning device according to claim 1, wherein the parallel rotation axis is located on or near a common axis with the rotation axis of the photoreceptor.
