ABSTRACT:
A color image reading apparatus is provided with a line sensor, an imaging optical system and a blazed diffraction grating. A color image is read by the line sensor through a rotatable reflective one-dimensional blazed diffraction grating serving as the color separation means. At least three color lights color-separated by the diffraction grating is synchronized with the scanning reading speed to rotate the diffraction grating in at least three directions, so that the reading of the color image is conducted by use of one line sensor.
