摘要： PURPOSE:To execute plural optical scans having no distortion by a single optical scanner by placing a cylindrical lens in front of a recording material, when plural beams of laser light are made incident on a single optical scanner and plural records are executed by the reflected light. CONSTITUTION:A cylindrical lens 12 is placed in front of recording materials 9, 10. Laser light from laser light sources 19, 20 is brought to optical modulation by optical modulators 17, 18, made elliptical by one direction beam magnifiers 15, 16 and made incident on an optical scanner at each dirrerent angle. The reflected light is separated by mirrors 13, 14 and executes an optical scan to the recording materials 9, 10. In that case, for instance, when a screen is in an A position, unless the cylindrical lens 12 exists, the laser light is irradiated on a C position, but when the lens 12 is provided, the distortion is corrected to a D position and also, when the screen is placed at a Q position, the distortion is corrected completely. Therefore, plural optical scans having no distortion can be executed by a single optical scanner.

摘要： PURPOSE:To control stable spot positioning by arranging an optical system for rotating the polarizing direction of light from a galvanomirror by 90 deg. between the galvanomirror and a focus optical system. CONSTITUTION:The rotary shaft of the galvanomirror 10 is fixed in parallel with the moving direction 100 of a crude positioning means 4. An optical beam from a semiconductor laser 8 is bent by a proper optical system so that an incident surface formed by an incident light beam on the galvanomirror 10 and the galvanomirror 10 is arranged rectangularly to the moving direction 100 of the crude positioning means 4. The optical beam polarized by the galvanomirror 10 is reflected by a mirror 16 having 45 deg. inclination from the incident surface, and further reflected by a mirror 18 having 45 deg. inclination from the incident angle formed by the incident light of the mirror 16 and the mirror 16 and projected on the surface of an optical disc 12 by a focus optical head 6 as a spot.

摘要： PURPOSE:To make an optical line sensor wide-area by arranging plural small- area base plate apart from one another spatially in the contact type optical line sensor used in a facsimile or the like. CONSTITUTION:An original 2 is illuminated with an illumination system 1, and its reflected light is condensed by a SELFOC lens 3. The light is separated to light advancing straightly and light reflected at 90 deg. by a half mirror 4. Optical sensor base plate 5 and 6 are arranged in such positions that they receive these beams of light respectively. The optical sensor base plate 5 and 6 are not connected but are spaced each other. The number of optical sensor base plate is increased in accordance with the area of the original to extend the optical line sensor up to the area of any size.
