ABSTRACT:
A light beam scanning apparatus includes a light source array composed of a plurality of light sources, which are arrayed in a predetermined direction, a shutter array composed of a plurality of electric shutters, which are arrayed in a direction corresponding to the predetermined direction, and a lens array composed of a plurality of lenses is located at positions corresponding to the positions of the electric shutters of the shutter array. The lenses form images of light beams, which are produced by the plurality of the light sources, as light spots having predetermined diameters on a material. A control circuit controls the timing, with which the light beams are produced by the plurality of the light sources, and the timing, with which the plurality of the electric shutters are opened and closed, such that the material may be scanned with the light spots.
