ABSTRACT:
A laser beam scanning apparatus includes plural laser beam sources for emitting laser beams modulated by a picture signal and having different characteristics from each other, a beam composition device for composing the beams emitted from the sources to form one laser beam, a deflecting device for deflecting the composite beam in a main scanning direction, and a beam splitter for splitting the deflected beam on the basis of the characteristic thereof. The apparatus further includes a beam-selecting device for selecting the beam in correspondence with the characteristic of the beam split by the splitter so as to transmit the beam with a specified characteristic and reflect the beam with a characteristic different from that of the transmitted beam.
