Abstract
A deflecting unit deflects a light beam emitted by each of a plurality of light-beam emitting units independently to scan surfaces of different bodies to be scanned. Each of a plurality of light-receiving units receives the deflected light beam at a predetermined position in a direction of the deflection. An incident angle of the deflected light beam with respect to a scanning line extending in a direction of scanning on a light-receiving surface of the light-receiving unit is set to be identical for all of the light-receiving units.
