摘要： An optical scanning apparatus includes a laser unit formed by integrating a semiconductor laser and collimator lens, an incident optical system for making a light beam emerging from the laser unit strike an optical deflector while keeping the light beam wider than the width of a deflecting surface of the optical deflector in the main scanning direction, and an imaging optical system for forming the light beam reflected/deflected by the optical deflector into an image on a scanned surface. The laser unit is shifted by a shift adjusting means in a predetermined direction with respect to the optical axis of the incident optical system so as to make an illuminance distribution of scanning lines on the scanned surface become substantially symmetrical about the scanning central axis.

摘要： The optical scanning apparatus has at least two scanning units S1 and S2 which are arranged so as to oppose each other with a deflecting unit interposed therebetween. The scanning units include incident optical systems La and Lb that guide light beams emitted from light source units 1a and 1b to the deflecting unit 4, and imaging optical systems Ma and Mb that cause the light beams for scanning deflected on a deflecting surface of the deflecting unit to form images on surfaces 8a and 8b to be scanned. The two scanning units are configured such that the main scanning planes thereof including an optical reference axis C0 have different heights from a bottom surface 4c of the deflecting unit in the direction of the rotational axis of the deflecting unit.

摘要： An optical recording/reproducing apparatus includes an irradiation optical system for irradiating a light beam from a light source onto a predetermined track of an optical recording medium having a plurality of neighboring tracks as a fine light spot so as to perform recording/reproduction of information or reproduction of information, and a detection optical system for detecting a returned light beam from the optical recording medium.

摘要： An optical scanning device corrects a scanning line curvature and prevents image quality degradation, while spatially separating a plurality of light beams at oblique angles of incidence despite its compact magnifying optical scanning device construction. The optical scanning device directs, to the deflection surface of an optical deflector via a cylindrical lens, the plurality of light beams emitted by a light source having a plurality of light emission sections, guides, via an f.theta. lens system to a surface being scanned, the plurality of light beams deflected by the optical deflector so that the plurality of light beams scan the surface being scanned. The f.theta. lens system has a plurality of rotationally asymmetrical lenses, the optical axes of which are substantially parallel with the light beams incident on the respective lenses, and each of the generatrices that connect the vertices of a radius curvature on a lens surface in the sub scanning direction of the rotationally asymmetrical lenses is curved in a sub scan direction.

摘要： In a scanning optical apparatus, a light beam emitted by a light source is caused to be obliquely incident on a deflection surface of an optical deflector in a sub scanning section through an optical device to form an image of the light beam deflectively reflected by the optical deflector on a surface to be scanned by an imaging optical system. A lateral magnification of the imaging optical system in a sub scanning direction is caused to change in accordance with a distance away from the on-axis to an off-axis along the main scanning direction.
