Abstract
An optical scanning device includes a light source and a MEMS optical deflector mounted on the same substrate, at least one optical path generation mirror configured to generate an optical path which causes a light beam emitted from the light source to enter the MEMS optical deflector, and a lens arranged between the light source and the first optical path generation mirror. A shielding plate has an elliptical aperture and is attached to the optical path generation mirror. The light beam from the lens has a peripheral edge on a cross section thereof, which is cut by the elliptical aperture.
