Image scanning device with linear illumination device for reading according to basic colors of split color separations with the use of a linear sensor

摘要

A linear illuminator for image reading by the use of a linear sensor comprises a linear illumination light source, a cylindrical rotational member provided on the circumference of the linear illumination light source, and a plurality of color separation filters installated on the rotational member, and by controlling the rotation of the rotational member, plural kinds of color separation linear illumination light are output in time series; hence making it possible to obtain an extremely miniaturized illuminator for image reading.
