摘要： A scanning unit in an image forming apparatus includes a light source, a coupling lens, an aperture, an image forming lens, and a polygon mirror. The light source includes a plurality of surface-emitting lasers. The coupling lens, the aperture, and the image forming lens are arranged on the optical path of light beams emitted by the light source. The polygon mirror deflects light beams of an image formed by the coupling lens towards a photosensitive drum for scanning. The focal length of the image forming lens in a sub-scanning direction is set to be equal to or smaller than an optical path length between the image forming lens and the aperture.

摘要： A scanning optical device includes a deflector deflecting a light beam emitted from a light source, and a pair of optical component groups arranged on both sides of the deflector in a sub-scanning direction and focusing the light beams deflected by the deflector to form images on a surface of an image carrier. Each of the optical component groups has a lens focusing the light beam deflected by the deflector in the sub-scanning direction, and a mirror reflecting the light beam passed through the lens toward the surface of the image carrier. One lens of one optical component group and the other lens of the other optical component group are supported so as to deform in the opposite directions each other in the sub-scanning direction when they are thermally deformed.

摘要： An optical writing device includes a light source, an optical deflector that deflects and scans light from the light source, a pre-deflector optical system that guides the light from the light source to the deflector, a post-deflector optical system that guides the scanned light to a target surface, a cover covering the deflector and including a first opening and a second opening provided at different positions, and a housing housing these optical elements. Light traveling from the light source to the deflector and the light scanned by the deflector are transmitted through the first opening but not through the second opening. During the rotation of the deflector, a forced inflow of air flowing from outside to inside the cover is generated in the first opening, and a discharged airflow flowing from inside to outside the cover is generated in the second opening.

摘要： A scanning system for use in an imaging apparatus includes a mirror assembly having a rotating mirror with a plurality of facets, a motor operatively coupled to the rotating mirror and closed loop control circuitry coupled to the motor. The mirror assembly generates a lock signal indicative of whether or not the motor is substantially at a target speed. A controller is communicatively coupled to the mirror assembly for controlling rotation of the rotating mirror, the controller generating a reference signal received by the motor assembly indicating the target speed for the rotating mirror. The reference signal is varied based at least in part upon an acceleration profile that accelerates the motor so that overshoot of the target speed is substantially reduced.

摘要： An optical device includes a surface-emitting laser array having a plurality of light-emitting portions; a package member on which the surface-emitting laser array is disposed; and a transparent member retained on the package member and disposed on an optical path of a light beam emitted by the surface-emitting laser array. The transparent member includes an incident plane on which the light beam emitted by the surface-emitting laser array is incident. The incident plane is inclined with respect to an emitting surface of the surface-emitting laser array at a first inclination angle which is smaller than a second inclination angle at which the light emitted by one of the light-emitting portions is incident on another, most-distant one, of the light-emitting portions via reflection by the transparent member.
