摘要:
A line-imaging lens condenses a light beam from a light-source unit in one direction to form a line image. An optical deflecting unit deflects the light beam passing through the line-imaging lens. An imaging optical unit images the light beam deflected by the optical deflecting unit in a spot shape on a scanning surface to be scanned. An adjusting unit adjusts a position of irradiation of the light beam from the light-source unit on the optical deflecting unit.

An image forming apparatus includes a plurality of image forming cartridges removably mounted to an apparatus body one above the other and a transfer belt support unit hingedly attached to the image forming apparatus that is movable between a first position covering the plurality of image forming cartridges and a second position uncovering the plurality of image forming cartridges. Each image forming cartridge can be mounted to or dismounted from the image forming apparatus when the transfer belt support unit is in the second position. At least one of the image forming cartridges can be mounted to or dismounted from the image forming apparatus in a direction other than along an axis of rotation of a photoconductive member located in an image forming member.

A multi-beam luminous source apparatus, an optical scanning apparatus, and an image formation apparatus are disclosed. The multi-beam luminous source includes a first member for supporting a coupling lens and a second member for supporting a control substrate that supports a Vertical Cavity Surface Emitting Laser (VCSEL). The first member and the second member are joined with a screw at a reference plane that perpendicularly intersects an optical axis of the coupling lens. The second member includes a base member A for supporting the control substrate and a base member B that includes a branch mirror, a convergent lens, and an optical detection sensor.

An image forming apparatus includes a plurality of cartridges disposed at intervals along an image transfer belt. A plurality of image writing devices is configured to write images. A partition member separates the plurality of cartridges from the plurality of image writing devices. The partition member defines slits configured to permit optical beams from the plurality of image writing devices to pass therethrough. The image transfer belt conveys the recording medium upward.
摘要:
An image forming apparatus including a plurality of light generators, an image transfer mechanism, a plurality of image forming cartridges corresponding to the plurality of light generators, and a housing including slots corresponding to the light generators. Each image forming cartridge has a photosensitive drum with an exposure position and a transfer position. The exposure position is facing a corresponding light generator and the transfer position is substantially diametrically opposed to the exposure position. The slots are positioned to allow light beams emitted from said light generators to pass therethrough onto the respective exposure positions. The housing is configured to house the plurality of light generators one above another.

摘要:
An image forming apparatus including an apparatus body, a single vertical stay disposed between optical writing devices and image forming cartridges and extending from a top wall to a bottom wall of the apparatus body, a plurality of horizontal stays disposed at least between consecutive image forming cartridges, and being attached to the single vertical stay, and a plurality of structural members disposed at least between consecutive image forming devices and being attached to the vertical stay. Further, the horizontal stays, the single vertical stay, the structural members and the apparatus body comprise a single structural body.
摘要:
An image forming apparatus including a plurality of image forming cartridges removably mounted to an apparatus body one above the other is disclosed. Structural members each partition off a space between nearby image forming cartridges mounted to the apparatus body. The apparatus is capable of obviating banding ascribable to the vibration of the cartridges.
摘要:
A method of arranging scanning optical components is described to provide a compact scanning optical system which includes a plurality of light sources for simultaneously emitting multiple image-forming beams towards a common image-reflecting surface such as a polygon mirror via an image-focusing element such as a set of vertically layered f.theta. mirrors.
