摘要： An optical beam scanning apparatus wherein a resin polygonal scanner deflects a light beam radiated from a laser diode as the polygonal scanner is rotating. The polygonal scanner is pressed by a pressing member against a scanner rest which rotates together with a rotary shaft of a motor and thus fixed on the scanner rest. The pressing member has a plurality of tabs, and the polygonal scanner is pressed evenly when the tabs pierce the polygonal scanner.

摘要： A laser beam scanning optical apparatus which has Moire fringes generating elements which is located near a position optically equivalent to a scanning surface and modulates a laser beam emitted from a laser source to generate Moire fringes. The Moire fringes generating elements comprises, for example, a first filter which has spatial grating and a second filter which has spatial grating which slants slightly with respect to the spatial grating of the first filter, the first filter and the second filter being arranged upstream and downstream respectively in an optical path. The laser beam scanning optical apparatus further has a light receiving element for receiving the Moire fringes generated by the Moire fringes generating elements. Focusing means for correcting a position of an image point of the laser beam is driven in accordance with an output of the light receiving element. For example, the light receiving element is a photoelectric element with a plurality of light receiving surfaces, each of which generates an electric signal in accordance with the laser beam incident thereto, and from a phase difference between the electric signals, the position of the image point is detected.

摘要： In an optical system, the scanning center axis of a scanning lens, the principal ray of a laser beam applied to the scanning lens, and the rotational axis of a polygon mirror are in one plane. By forming a thin film layer on the deflecting facets, the exposure quantity of a photo conductor, which decreases as the incident angle to the deflecting facet increases, is corrected. The thin film layer has the increasing ratio of the reflectance that increases as the incident angle, which principal ray of the laser beam forms with the normal line to the deflecting facet of the polygon mirror, increases.
