ABSTRACT:
A beam deflector device in which two light beams from two light sources are simultaneously applied through movable reflectors to a beam deflector scanning a drum. The beams are also applied, through a beam splitter to two photodetectors used to control the position of the respective reflector. The two beams are separated before they are applied to the photodetectors by means of polarization plates, color filters, diffraction gratings or prisms.
