ABSTRACT:
In a laser printer or the like, for the purpose of increasing a recording speed, the number of revolutions of a laser beam deflector is not increased but a plurality of scanning lines are simultaneously scanned. To this end, a plurality of laser beams with an angle of incidence slightly varied are simultaneously incident upon one and the same laser beam deflector. In the event that places for installation of a plurality of light sources are hindered each other by other light sources, light sources different in polarization surface from each other are used, and when beams are combined by means of a polarization beam combiner, a combined beam which is different in angle of emergence through a fine angle each other can be obtained without loss of light.
