LASER BEAM SCANNING DEVICE

摘要

PURPOSE:To provide the laser beam operation device which corrects the inclination of a scanning line by slanting only a reflecting means while holding dot pitches at equal intervals at the same time without causing defocusing. CONSTITUTION:The laser beam scanning device 1 is equipped with plural reflecting means for reflecting a laser beam so that the laser beam is guided to a photosensitive body 11. A mirror system 6 consisting of a couple of mirrors arranged at right angles to each other and a mirror system which reflects the laser beam to the photosensitive body 11 are installed rotatably on an axis perpendicular to the scanning direction of the laser beam and the former mirror system 6 is rotated according to the angle of rotation of the latter mirror system to adjust the scanning direction on the photosensitive body 11.
