Abstract: A first holder plate that holds a first laser emitting portion and that has a first insertion hole formed therein, a second holder plate that holds a second laser emitting portion and that has a second insertion hole formed therein, and a base plate that supports a first collimating lens and a second collimating lens and that has a first screwing hole and a second screwing hole formed therein, are continuously formed by a bending process. A slit plate having two slits bored therein which are disposed in parallel and in a sub scanning direction is provided between a reflecting mirror and a cylindrical lens. The reflecting mirror combines the optical paths of two laser beams emitted from the two laser emitting portions such that the optical paths are matched in a main scanning direction. The cylindrical lens allows the two laser beams to converge in the sub scanning direction.

Abstract: Printers that correct for polygon phasing errors. Such printers include a raster output scanner, a moving photoreceptor, a page sensor for sensing the position of an image area, a start-of-scan sensor for sensing the start of scan, a light valve array having a plurality of electrically controlled light valves for selectively passing light, and a system controller that controls the light valve(s). The system controller initially selects one of the light valves. When the page sensor senses the beginning of a page the system controller starts selecting sequential light valves at a controlled rate. After a start-of-scan occurs the system controller stops sequencing the light valves. The light valve that passed light when the start-of-scan occurred continues to pass light. Beneficially, the system controller monitors the photoreceptor motion. If the photoreceptor motion changes the system controller then selects a light valve that moves the scan line toward the proper position.

Abstract: Apparatus for use in an optical scanner for accurately controlling, from scan to scan, the position in which the horizontal scan line is formed. A closed electrooptical feedback loop is employed to sense, prior to the formation of each horizontal scan line, the vertical position of the scanning light beam in the plane of the recording element and, in the event its position is displaced from a nominal position, to produce an error signal to move the beam to the nominal position.

Abstract: A scanning system device has a predetermined aberration as it scans or switches light along selected optical paths. A deformable membrane receives the light and introduces an inverse “aberration” that offsets that of the scanning system. In one embodiment the scanning system includes a torsion arm that supports an oscillatory body. The torsion arm and/or body can be machined from metal, micromachined in silicon or formed in a variety of other ways. Alternatively, the scanning system may include a rotating polygonal scanner or other type of optical scanner. In another approach, an optical switch replaces the scanner.

Abstract: The light beam scanning method and apparatus perform light beam scanning of a cylindrical internal surface scanning type, a cylindrical external surface scanning type, and a plane scanning type, where when a sheet-like object to be scanned is scanned by a light beam emitted from a light source, at least one of lateral displacement and longitudinal displacement of a light beam and aberration in an optical system is compensated by controlling a wave front of the light beam with a wavefront control device. Also, when the lateral displacement, longitudinal displacement, and the aberration are caused by change of an environmental temperature, it is possible to measure the environmental temperature and to perform compensation through the control of the wave front by the wavefront control device based on the measured environmental temperature. Also, when scanning is performed using a plurality of light beams, it is possible to align scanning positions of the plurality of light beams in an auxiliary scanning direction in a parallel manner by displacing the scanning positions through the control of the wave front of at least one light beam using the wavefront control device.

Abstract: A multi-beam scanning optical apparatus employs a beam pitch adjusting system in which the position of a first beam is detected by using a beam position detecting system composed of a knife edge shaped plate and one photo sensor, and in which the optical path of the second beam is corrected so that the position of the second beam may be at a specified distance from the position of the first beam. A further embodiment of the beam pitch adjusting systems includes a beam position detecting system using a line position sensor by CCD or PSD. A yet further embodiment of the beam pitch adjusting system includes a position detecting system utilizing the power of a beam efficiently by disposing a focusing lens on an optical path of the beam. Hence, beam pitch adjustment is facilitated, the pitch adjustment precision is enhanced, the range of pitch adjustment is optimized, the number of parts is reduced, and space is saved.
