Abstract
The light beam scanning device has a casing injection molded from magnesium or magnesium alloy as the material. A polygon mirror and a motor are sealed in the inside of the casing and a cover covering the latter. Since the thickness of the magnesium or magnesium alloy material can be reduced, heat generated from a motor is dissipated satisfactorily. Heat dissipating fins are formed to the casing to promote heat dissipation and enhance the strength of the casing.
