Patent ID: 8780428

Claim:
A light scanning device comprising: a light source configured to emit a light beam; a deflector configured to deflect and scan the light beam from the light source in a main scanning direction; a driving source that drives the deflector; and a housing including a support wall to which the driving source is fixed, wherein the support wall has a first surface to which the light source is fixed, a second surface to which the driving source is fixed and that is recessed with respect to the first surface in a direction perpendicular to the first surface, and a third surface that connects the first surface and the second surface and is inclined to form obtuse angles relative to the first surface and the second surface, wherein the light beam emitted from the light source travels across the first surface and the third surface to the deflector, and wherein the light beam is deflected by the deflector across the third surface and the first surface in the main scanning direction.
