摘要： An optical scanner includes a plurality of scanning optical systems each of which scans a different surface to be scanned and includes a light source configured to emit a light beam, an optical deflector having a plurality of reflection surfaces, and a synchronization detector configured to receive the light beam deflected by the optical deflector and detect a timing to scan an effective area of the surface to be scanned with the deflected light beam before a scanning is started or after the scanning is completed. The synchronization detector of one of a pair of scanning optical systems is disposed on a scanning end side to determine the scanning timing, and the synchronization detector of the other one of the pair of scanning optical systems is disposed on a scanning start side to determine the scanning timing.

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： An optical scanning device includes a light source, a light-beam splitting unit, a deflector, and a scanning optical system. The light-beam splitting unit splits a light beam from the light source into a plurality of light beams, so that the light beams are each incident to any one of reflecting surfaces of the deflector while having a phase difference of approximately π/2. The scanning optical system receives the light beams from the deflector and projects each of the light beams onto a corresponding target surface.

摘要： An optical scanning device includes a lens having a negative optical power at least in a sub-scanning direction and a lens having a positive optical power at least in the sub-scanning direction between a light source and a deflecting unit. The optical scanning device further includes a coupling lens and an adjusting lens whose positions can be adjusted in an optical axis direction and then bonded with ultraviolet curing resin. Therefore, the magnification of an optical system can be adjusted and consequently a desired scan-line interval can be obtained.

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.

摘要： An optical scanning unit includes a rotatable multi-faceted mirror having a plurality of faces reflecting light flux emitted from a light source to scan a scanning area in a main scanning direction. A width of the light flux striking the rotatable multi-faceted mirror is smaller than a length of a face of the rotatable multi-faceted mirror. The entire of light flux striking the rotatable multi-faceted mirror is reflected at a first face when the light flux reflected by the rotatable multi-faceted mirror is directed to the center portion of the scanning area. A part of the light flux striking the rotatable multi-faceted mirror is reflected at the first face while the remaining of the light flux is reflected at a second face when the light flux reflected by the rotatable multi-faceted mirror is directed to a least one of the two end portions of the scanning area.
