Abstract:
An optical scanning device includes a housing, a laser light source outputting a laser light, a polygon mirror arranged in an arrangement space and deflecting the laser light to scan a predetermined object with the laser light while rotating, a polygon motor rotating the polygon mirror, a control board arranged in the arrangement space and controlling the polygon motor, and a flow-control member arranged in the arrangement space and guiding an airflow generated by a rotation of the polygon mirror to an outside of the arrangement space to circulate the airflow within the housing.
