    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 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： An optical writer includes a housing, a light source, a deflector, and a plurality of optical elements. The housing includes a plurality of surfaces, one of which includes a substantially flat portion having an opening formed therein and a curved portion curved in the shape of an arc of a circle in cross-section. The light source is enclosed within the housing and projects light through the opening and onto a target. The deflector is enclosed within the housing and deflects the light projected from the light source in a main scanning direction. The plurality of optical elements is enclosed within the housing and directs the light deflected by the deflector onto the target.
