Abstract

PURPOSE:To eliminate a mixture of signals and thus obtain high resolution, by detecting a color signal sent from the unit region corresponding to the desired resolution on an original with several photosensors that read the colors. CONSTITUTION:The light emitted from a point 9 in the unit region of reading on the illuminated part is condensed by the lens 5 on the image forming surface 11 of an original and then scattered through the minute aperture 12 provided on the light shielding plate 6. The photosensor 1 is put into flux of the scattered beams to detect the information light. The sensor 1 consists of three parts 1-R, 1-G and 1-B to detect the red, green and blue colors each, and then detects the color information of the unit region 9. The luminous flux sent from the point 10 in another unit region on the original 4 is cut off by the plate 6 and thus never mixes into the sensor 1.
