Abstract: A laser scanning device is provided with a laser source which emits a laser beam, a deflector which dynamically deflects the laser beam emitted by the laser source, the laser beam scanning in a main scanning direction within a predetermined angular area, a photodetector which receives light and output electronic signal corresponding to the received light, and a sensor lens arranged to receive the laser beam scanning at a predetermined scanning range, the sensor lens having power at least in the main scanning direction, the sensor lens converging the incident laser beam on the photodetector, the sensor lens having width in the main scanning direction varying in the auxiliary scanning direction.

Abstract: A multi-beam scanning device includes a light source for emitting a plurality of laser beams, a polygon mirror for deflecting the laser beams so that the laser beams scan across an object surface in a main scanning direction, an fnull lens disposed between the polygon mirror and the object surface, and a cylindrical lens that converges each laser beam in a vicinity of the polygon mirror in the auxiliary direction. A mirror is disposed between the light source and the cylindrical lens which deflects the laser beams in the auxiliary scanning direction. The mirror is rotatably supported by a mirror holder such that the traveling direction of the laser beams deflected by the mirror can be adjusted.
