摘要： An optical scanning unit includes a light source that emits a light beam, a light deflector that deflects the light beam from the light source, and a scanning optical system that focuses the light beam deflected by the light deflector on a scanning surface. The light beam from the light source is at an angle in a secondary scanning direction with respect to a normal to a reflecting surface of the light deflector. At least one surface of the scanning optical system does not have a curvature in the secondary scanning direction, being tilted and decentered in the secondary scanning direction.

摘要： An optical scanning apparatus includes M number of light sources that includes M number of semiconductor lasers and M number of coupling lenses, where M is a positive integer, a deflecting scanning unit that deflects laser beams from the light sources to a surface to be scanned, and a transmission-type prism that deflects optical path of the laser beam from at least one of the light sources by an infinitesimal amount of angle. The prism is disposed between the light sources and the deflecting scanning unit, has an incident surface and an output surface nonparallel to each other, and can rotate around an axis of rotation substantially parallel to the optical path of the laser beam.

摘要： An optical scanning apparatus including a pulse modulation mechanism, a laser light source, a light deflecting mechanism, and a scan-imaging device. The pulse modulation mechanism performs a pulse modulation to input image data to output pulse-modulated image data. The laser light source generates a laser light beam according to the pulse-modulated image data. The laser light beam has a wavelength variation smaller than 2.0 nm per one pulse of the laser light beam. The light deflecting mechanism converts the laser light beam into a scanning laser light beam. The scan-imaging device condenses the scanning laser light beam into a scanning light spot on a surface to be scanned.

摘要： An optical system includes three optical systems. The first has a coupling lens. The second includes a lens having a positive power in a vertical scanning direction and forms the light flux into a line image extending in the horizontal scanning direction on a deflector. The third includes a first lens having a positive power in the horizontal scanning direction, and a second lens having a positive power in the vertical scanning direction. Lateral magnification in the horizontal scanning direction is set larger than that in the vertical scanning direction. Temperature near the first lens is maintained higher than that near the second lens.

摘要： An optical scanning device deflects one or a plurality of light flux(es) originating from a light source by an optical deflecting unit, gathers the deflected light flux(es) to cause it(them) to form a beam spot(s) on a surface to be scanned by a scanning and image-forming optical system, and, thus, performs optical scanning of the surface to be scanned. The scanning and image-forming optical system includes one or a plurality of optical component(s) including a lens. At least one surface of the lens included in the scanning and image-forming optical system is a sub-non-arc surface having an arc or non-arc shape in a main scanning plane, and a non-arc shape in a sub-scanning plane. The sub-non-arc surface is formed in a lens in which a diameter of a light flux passing through the scanning and image-forming optical system is largest in the sub-scanning plane’.

摘要： An optical scanning device of the present invention includes a simple scanning lens. At least one of opposite surfaces of the lens has a nonarcuate shape, as seen in a polarization plane. At least one of the opposite surfaces is a special toric surface. Further, in a plane perpendicular to the polarization plane, the lens has a meniscus shape concave toward a polarizer. With this configuration, the lens achieves a desirable uniform velocity scanning capability and a desirable field curvature in the main scanning direction. The lens is therefore free from errors in configuration ascribable to molding while reducing the limitation on the tolerance of optical elements in the optical axis direction as to assembly.
