ABSTRACT:
A method for controlling exposure light beams for use in a picture reproducing machine such as a color scanner and a color facsimile, wherein a light beam is supplied to an acoustooptical deflector and is deflected thereby to obtain diffraction light beams which are incident to fixed light paths and are used for exposing a recording film, and wherein the diffraction light beams are controlled by varying a frequency of a supersonic wave supplied to the acoustooptical deflector so that each diffraction light beam may be or may not be incident to the respective light path.
