ABSTRACT:
The essential feature of the color image recording apparatus of the present invention is that it uses a laser light source capable of simultaneous emission of laser beams associated with exposure to R, G and B light. The apparatus also uses a light deflector and a device for selectively reflecting or transmitting said laser beams, for example, a rotating polygonal mirror in which at least one of the reflecting faces has a different spectral characteristic of reflection than other faces or a light deflector and at least one color filter that operates in synchronism with the light deflector.
In the present invention, a laser beam having a wavelength associated with exposure to light either one or R, G and B colors is separated from the light beams emitted from the laser light source, and the recording material is exposed to successive beams of different colors, one for each scanning line, to insure exposure for a full-color image by three scanning lines. Since this obviates the need for providing the reflecting mirror and the dichroic mirrors that have been necessary to align the optical axes of R, G and B laser beams in the prior art color image recording apparatuses, it becomes possible to construct a compact and inexpensive color image recording apparatus.
