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 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： An optical writing device includes a dichroic mirror and a deflection beam splitter. The dichroic mirror causes a light beam to pass therethrough or reflect depending on the wavelengths of the light beam. The deflection beam splitter causes a light beam to pass therethrough or reflect depending on a direction from which the light beam is received.

摘要： The image forming apparatus includes a chassis; plural image bearing members; plural optical scanning devices having the same configuration and located on respective installation positions of the chassis after installed thereon to scan the image bearing members with light beams; and plural incompatibility imparting mechanisms. The incompatibility imparting mechanisms are located on the corresponding optical scanning devices, and have the same configuration and the same initial state before the plural optical scanning devices are installed on the chassis, but achieve incompatible states after the optical scanning devices are installed. When the optical scanning devices in the incompatible states are detached from the chassis and then attached again thereto, the incompatibility imparting mechanisms prevent the corresponding optical scanning devices from being set to positions other than the respective installation positions.
