摘要：
An optical scanning device for scanning a subject medium with a scanning beam that is oscillated by a polygon mirror along a straight line on the subject medium is provided with a rotational speed variation restraint partition which operates to restrain an occurrence of momentary rotational speed variations of the polygon mirror due to turbulence of a current of air that are caused by high speed rotation of the polygon mirror.
