摘要：There are provided a plurality of light sources emitting different color lights, and switch means for selectively lighting either one or all of the light sources. The lights reflected by a multicolor manuscript are converted into electric outputs by an image sensor. The output of the image sensor of the portion of the manuscript having the same color as the lighted light source is caused to exceed a predetermined binarizing level, whereby that portion of the manuscript is prevented from being read.
