ABSTRACT:
A color exposing device for imagewise scanning a photosensitive recording medium with light beams corresponding to two or more colors, respectively. The recording medium has photosensitive materials sensitive to respective bands of wavelength of the light beams, to produce images in the different colors. The device includes a light source for producing a radiation including two or more wavelength components whose wavelengths fall within the respective wavelength bands of the light beams, a color separation element for separating the radiation ito the wavelength components to provide the light beams, which are propagated along respective ligh paths, optical modulators disposed in the light paths, respectively, for modulating intensities of the light beams, according to respective color image signals, respectively, to thereby provide respective modulated light beams, and a scanning arrangement for irradiating a surface of the recording medium with the modulated light beams along a line, to produce a line of color images.
