摘要： An optical deflector is disclosed which is capable of preventing unnecessary reflection by a member disposed behind a reflecting portion. The optical deflector includes a substrate portion, a reflecting portion can swing about a swinging motion axis with respect to the substrate portion, and an aperture stop portion which includes an aperture and blocks at least part of a light beam other than a light beam entering the aperture among an incident luminous flux to the optical deflector. The aperture allows passage of the incident luminous flux toward the reflecting portion and that of an emergent luminous flux reflected by the reflecting portion. At least part of an aperture rim of the aperture stop portion has a shape that makes the width of the aperture narrower from a light-beam-incoming side toward a reflecting portion side.

摘要： A compact light scanning apparatus is disclosed which can provide a high light scanning efficiency. The apparatus includes a scanner that scans a light beam from a light source to form an image in an effective scan area, and a light detector that detects light. The light scanning apparatus includes a light-introducing member that introduces a partial light beam component of the light beam within its light beam width to the light detector in a state in which the light beam scanned by the scanner proceeds toward outside the effective scan area.

摘要： To obtain a positioning reference portion with good processing accuracy, which is formed of a newly-formed surface, a blank is press-molded by an upper mold, whereby a vertex portion abuts on an inner wall portion of a lower mold. In such a way, an oxide film that covers the vertex portion is broken by an internal pressure of the blank, and a raw material without oxide is moved by viscous flow from an inside thereof as illustrated by arrows. The raw material without oxide moved by viscous flow is thrust against the inner wall portion of the lower mold, whereby a newly-formed surface is formed, and this newly-formed surface serves as a positioning reference portion of an optical element. The newly-formed surface has surface roughness of the inner wall portion of the lower mold transferred thereto, and the positioning reference portion having good roughness is formed.
