摘要： A color image scanner is constructed by a three primary color LED array (4) for illuminating an original (2) to be read out, a monochromatic image sensor array (3) and a rod lens array (1) disposed between the original (1) and the image sensor array (3). The focusing parameters of the three kinds of refractive index distribution type rod lenses (11, 12, 13) constituting the rod lens array (1) are set so that each of the operating wavelength band and the predetermined wavelength is different among the kinds, the lens length Zo is equal among the kinds, and the conjugate length TC at each predetermined wavelength is substantially equal among all the kinds. Accordingly, when a color image reading operation is carried out by using the rod lens array which is effective in compactness and brightness, the chromatic aberration of the rod lens array can be sufficiently reduced and high-resolution can be implemented at low cost.
