摘要： First, an inner tube member is accommodated in an outer tube member. Then, rigid powder, having high rigidity and a hard-to-magnetize characteristic, into the inner tube member. Next, magnetic powder is filled into a recessed portion of the inner tube member. Then, the inner tube member is drawn out of the outer tube member. Then, a composite filler composed of the rigid powder, magnetic powder and outer tube member is subjected to a cold hydrostatic pressure pressing process as pre-processing. Next, the composite filler is heated and solidified into a billet. Then, the billet is subjected to a hot extrusion process so that it is formed into a bar-shaped workpiece. The bar-shaped workpiece is rolled onto a roller, and then the outer tube member is peeled off. Next, the bar-shaped workpiece is subjected to a cutting process so that it is formed into an elongated bar. Then, a magnetic section of the elongated bar is magnetized into a scale structure.

摘要： An optical scanner is capable of effectively correcting a difference with respect to the sub-scanning direction between the positions of optical spots for scanning photoconductor drums of a tandem type color image forming apparatus. The optical scanner includes an optical axis adjusting part. The optical axis adjusting part uses a deflecting mirror or a wedge-shaped prism to deflect the optical axis of an optical beam with respect to the sub-scanning direction. As a result, it is possible to accurately correct a resist difference among individual image forming stations and form a high-quality color image without any color displacement.

摘要： A coupling lens arranged on an optical path of an optical beam from a VCSEL, which has a refraction plane and a diffraction plane that respectively change a power according to a temperature change and suppresses a beam-waist position change in a main-scanning direction and a sub-scanning directions on the scanning surface caused by the temperature change, by a wavelength change of the optical beam caused by power changes of the refraction plane and the diffraction plane and the temperature change. A deflecting unit deflects the optical beam that passed through the coupling lens. A scanning optical system condenses a deflected optical beam on the scanning surface.

摘要： An optical scanner includes a light source, an optical coupler, an optical line image unit, a deflector, and an optical scanning unit. The optical scanning unit includes scanning lenses that guide the beams to a surface to be scanned. A surface on the deflector side of the scanning lens closest to a deflection reflecting surface has a negative power in a vertical scanning direction, and is a special toric surface in which a radius of curvature in a vertical scanning changes from an optical axis of the lens surface toward a periphery of the horizontal scanning direction. An F number of the beams toward the surface to be scanned of the scanning lens in the vertical scanning direction is larger in a peripheral part than in a central part in an effective scanning width.
