徴とする高分解能多面鏡レーザー走査装置。 A polygonal mirror is rotatably driven by a motor that has several mirror surfaces and reflects the light flux so as to direct it toward a cylindrical lens, and a polygon mirror body is placed at a position to properly direct the light flux toward the mirror surface of the polygon mirror. a plurality of spectroscopic lenses movable vertically and horizontally; the cylindrical lens located between the polygon mirror and the photosensitive drum for converging the light flux and projecting it onto the photosensitive drum; and a motor drive. The spectroscopic lens consists of a photosensitive drum that rotates at a constant speed, a synchro detector for system tuning, and a position detection sensor for maintaining and controlling the spacing between scanning lines. generate a scanning speed of light of
High-resolution polygonal mirror laser scanning device, characterized by increasing scanning speed and improving resolution quality.
