摘要： An optical scanner includes a light source including a plurality of light emitting elements, a polygon mirror which deflects light from the light source for scanning a surface of a subject, an optical element arranged between the light source and the polygon mirror, having optical power in a sub scanning direction, a synchronous detector which detects the light deflected by the polygon mirror for synchronous detection and generates a signal for controlling a timing at which the scanning of the surface is started, and a fixing element which secures one end of the optical element. The light emitting elements of the light source are aligned with a certain tilt angle relative to the sub scanning direction. Light from one of the light emitting elements disposed closest to the fixing element in a main scanning direction is used for synchronous detection.

摘要： An optical writing unit includes in a housing a light source projecting a light beam, a deflector to deflect the light beam projected from the light source, a focusing lens, and a lens adjusting device. The focusing lens is long in a main scanning direction and focuses the light beam onto a scan target. The lens adjusting device rotates the focusing lens about a substantially center portion thereof as a rotation fulcrum on a plane perpendicular to an optical path of the light beam so as to adjust the position of the light beam illuminating the scan target. The focusing lens has an asymmetric cross-section relative to a center line of the focusing lens in a direction of the optical path in a sub-scanning plane perpendicular to the main scanning direction, and the center of gravity of the focusing lens is offset from the center line toward the rotation fulcrum.

摘要： In a light beam scanning device, a plurality of light sources, which irradiates a plurality of light beams in a first direction and is retained by a holder, are disposed at distance from one another in a second direction orthogonal to the first direction. The plurality of light beams are incident, via a coupling optical system, to deflecting and reflecting surfaces of a deflector from a direction that is tilted with respect to a plane orthogonal to the rotational shaft of the deflector. The holder is supported by a housing of the light beam scanning device at a plurality of different positions in a third direction extending from the light source to the coupling optical system.

摘要： An image forming apparatus includes a plurality of image carriers and an optical writing device including light sources that emit light beams of different wavelengths, a deflector that deflects the light beams emitted from the light sources and synthesized on an identical axis in a sub-scanning direction, a first beam separator, a second beam separator, a first imaging device, and a second imaging device. The first beam separator and the second beam separator are located between the first imaging device and the second imaging device and transmit or reflect the light beams according to travel directions or wavelengths thereof. One of the targets is scanned with the light beam transmitted through the second beam separator. Another target is scanned with the light beam reflected by the second and first beam separators. The first and second imaging devices narrow the beams in the main scanning direction and the sub-scanning direction, respectively.
