Abstract
A multicolor reading device is provided with a high intensity illuminating light source and a plurality of filters sequentially arranged in front of the source to provide monochromatic light of differing hues. The light is transmitted from the source to the platen by optical fibers or the like which are bundled on the source side and arranged in a line at the platen.
