    摘要: There is described a light beam deflection apparatus in which the distortion of the polygon mirror is reduced, and the mounting accuracy of the polygon mirror is improved. The light beam deflection apparatus includes a base plate, a coil being stationary relative to the base plate and a mirror unit being rotatable with respect to the base plate. The mirror unit includes a polygon mirror, a rotating disk to mount the polygon mirror, a rotating yoke fixed to the rotating disk, a magnet attached to the rotating yoke and located opposite the coil and a buffer member inserted into a gap between the polygon mirror and the rotating yoke.

    摘要: There is provided a polygon mirror comprising a mirror body shaped in a regular polygon and having circumferential surfaces, a top surface and a bottom surface, a reflection surface formed on each of the circumferential surface, a machining reference surface provided on one of the top and bottom surfaces, machined to form a mirror surface and used as a reference surface for machining the reflection surface on each of the circumferential surfaces and an assembling reference surface provided on one of the top an bottom surfaces, shaped in parallel to the machining reference surface, machined to form a rough surface and used as a reference surface for assembling the polygon mirror. The polygon mirror has a high degree of reliability in terms of stable optical characteristic when a polygon mirror and a flange member are bonded with each other.
