Abstract
A color document image reading device provides for inputting of a color image on an original document to various kinds of image processing apparatus. The color document image is decomposed into predetermined pixels, then photoelectrically converted into an electric signal, and then outputted with the pixels arranged time-serially. A filter has a plurality of color separation filter elements which are arranged in a flat configuration while being physically isolated from each other by a light-intercepting area having a predetermined width. The filter is driven by filter drive means in a reciprocal motion in a direction perpendicular to an optical axis, whereby any of the filter elements is brought into alignment with the optical axis. The filter is supported in such a manner as to be movable in a direction of movement of the filter drive means while being prevented from moving in the other directions.
