Abstract
A color image reading device for reading a document image imaged on a line image sensor, wherein the line image sensor is a CCD including a first pixel line consisting of pixels having a first reading spectral characteristic and a second pixel line consisting of pixels having the second and third reading spectral characteristics arranged alternately; a two-layer dichroic mirror is provided on the CCD, said optical element for generating double images of an optical image corresponding to said first reading spectral characteristic and another optical image corresponding to the total of said first and second reading spectral characteristics; and the separation distance between the double images generated and imaged on the CCD by the dichroic mirror is approximately equal to the distance between said two lines of pixels on the CCD.
