Abstract
A mounting structure for mounting a polygon mirror on a rotating body includes a mirror seat formed in the rotating body for mounting the polygon mirror thereon and a fixing device for fixing the polygon mirror on the mirror seat. The mirror seat is formed on the periphery of the rotating body, and the polygon mirror includes in a top surface thereof an annular groove of a rectangular section at a position thereof a predetermined radius from the center of rotation of the rotating body. The fixing device comprises a planar ring-shaped anchoring member fixed to the rotating body and having along a peripheral portion thereof a plurality of downwardly extending conical or semispherical projections. The projections of the anchoring member engage with the annular groove in the polygon mirror and press against the upper edge of the inner periphery of the groove by point contact to thereby fix the polygon mirror in position. Thus, the polygon mirror is not thrown out of the balance over time and no pressing force is transmitted to the mirror surfaces.
