摘要： An exposure unit includes a light-emitting element array and a lens array. The light-emitting element array includes a plurality of light-emitting elements that are disposed in a first direction and each emit a light beam. The lens array faces the light-emitting element array in a second direction that is orthogonal to the first direction, and focuses the light beams emitted from the respective light-emitting elements. The following expression [3] is satisfied. A symmetric property, determined from the following expression [1], of a light amount distribution in the first direction of at least one of the light beams focused by the lens array satisfies the following expression [2]. S=|(HL−HR)/(XE/2)| [1] 0≤S≤0.65 [2] Lo≠LB [3]

摘要： A focus adjustment mechanism for adjusting a focus position of a printhead includes a rotatable pin that is rotatable around a pin axis. The rotatable pin includes a cam section located having a surface whose radial distance from the pin axis varies around its perimeter, and a gripping feature. An adjustment plate includes a gripping feature and is adapted to fit over and engage with the gripping feature of the rotatable pin such that the adjustment plate rotates together with the rotatable pin. A fastener fastens the adjustment plate to a support structure when the adjustment plate is positioned in a desired orientation. The printhead includes a frame feature which is pulled firmly against the cam section of the rotatable pin such that as the rotatable pin is rotated the frame feature rides on the surface of the cam section thereby adjusting the focus position of the printhead.

摘要： An optical scanner includes a light source for projecting a light beam against a target, a deflector for deflecting the light beam, a coupling lens, an optical element, a light source support member, and a housing. The coupling lens directs the light beam to the deflector. The optical element focuses the light beam deflected by the deflector into a desired shape. The light source support member supports the light source. The housing houses the light source supported by the light source support member, the deflector, and the optical elements. The housing includes at least two coupling lens mounts on which the coupling lens is fixed on an optical path between the light source and the target, and accommodates multiple light source support members. The coupling lens is fixed to the coupling lens mount using an adhesive agent after an optical axis of the light beam is aligned.

摘要： An optical printer head has an array of lenses that project light emitted by an array of LEDs onto a charged photosensitive drum to form a latent image on the drum surface. A resin film adhered to the exposed surfaces of the lenses prevents chemical reaction between nitric acid, formed as a consequence of ozone produced during electric charging of the photosensitive drum, and alkali components on the surfaces of the lenses thereby preventing clouding of the lens surfaces and dimming of the projected light. The resin film has a thickness of 10 to 100 microns and may be formed of polyvinyl chloride, polyethylene terephthalate or polymethyl meta acrylate.

摘要： An optical print head having a substrate on which multiple light sources aligned in a main scanning direction are mounted to emit beams of light in a direction perpendicular to a surface of the substrate; a lens array to focus the beams of light on an image bearing member to form an image thereon; a housing having a guiding portion extending in the main scanning direction to position the substrate and the lens array; a cleaner to clean a light-emitting surface of the lens array while moving in the main scanning direction; a moving device to move the cleaner; and a supporting member to support the housing and the cleaner. The supporting member rotatably supports the cleaner about a shaft and the guiding portion contacts the cleaner against the light-emitting surface of the lens array with a constant force over the main scanning direction during cleaning of the light-emitting surface.
