する光ビーム走査装置。[Claims for Utility Model Registration] Two light beams incident from opposite directions are reflected by rotating a mirror having reflective layers on both sides and scanned on a photosensitive material via an fθ lens. In the light beam scanning device, the rotation axis of the mirror is set at a distance L=t2×√2(t; thickness of the mirror) from the optical axis of the opposing light beam, and the mirror is A light beam scanning device characterized in that the reflected light almost coincides with the optical axis of the fθ lens when the reflected light is at a position of 45° with respect to the optical axis.
