摘要： A novel laser beam scanning system which stores fundamental components in an optical unit by way of including a laser light source, a photosensor for detecting image-writing starting point per scanning, a lens for focusing a laser beam from the laser light source, and a lens for condensing a laser beam reflected by a polygon mirror on the photosensor. The laser beam reflected by the polygon mirror sequentially scans the photosensor, the laser light source, and a recording medium. When the laser beam reflected by the polygon mirror scans the laser light source, the laser light source ceases light-emitting operation. Furthermore, the laser beam reflected by the polygon mirror is condensed on an edge of a photoreceptive surface of the photosensor.
