摘要： An optical deflector of the present invention includes a movable mirror and torsion bars supporting the mirror and formed integrally with the mirror. The mirror reciprocatingly vibrates to reflect a light beam to thereby deflect it. The mirror is curved in the form of an arch in a section including at least the torsion bars. The mirror deforms little during vibration even if it is thin. Small power can cause such a thin mirror to vibrate with a large amplitude.

摘要： In this optical scanning device, a plurality of scanning optical systems are arranged in a main scanning direction. Each of the scanning optical systems includes a deflecting unit performing an optical scanning by oscillation. Scanning frequencies of the deflecting units are substantially equal to one another. Each of the deflecting units is provided with means for varying the scanning frequency. The scanning frequency of each of the deflecting units is set midway between a maximum value and a minimum value of a resonance frequency intrinsic to the deflecting unit.

摘要： A deflector mirror is disclosed that includes a mirror substrate configured to vibrate in a reciprocating manner on beams as a torsional rotary shaft so as to deflect a light beam emitted from a light source. The mirror substrate includes multiple regions in each of portions thereof extending from the torsional rotary shaft to respective ends of the mirror substrate, the regions being different in flexural rigidity.

摘要： An optical deflecting unit includes a torsion mirror which is pivotable about an axis and has a deflecting reflection surface which receives a light beam at an incident angle inclined with respect to a plane which is perpendicular to the axis and the deflecting reflection surface, and at least one fixed mirror surface confronting the torsion mirror and arranged so that the light beam is reflected between the torsion mirror and the at least one fixed mirror surface a plurality of times. A moving direction of a reflection position of the light beam on the torsion mirror in a sub scan direction reverses.
