Abstract
An optical beam scanning apparatus wherein a resin polygonal scanner deflects a light beam radiated from a laser diode as the polygonal scanner is rotating. The polygonal scanner is pressed by a pressing member against a scanner rest which rotates together with a rotary shaft of a motor and thus fixed on the scanner rest. The pressing member has a plurality of tabs, and the polygonal scanner is pressed evenly when the tabs pierce the polygonal scanner.
