ABSTRACT:
There are provided a plurality of light sources for applying light beams of red, green, and blue to a document surface. An optical system condenses light that is reflected from the document surface. A plurality of sensors are provided in the image formation section of the optical system, and read an image of the document. A reading device scans the sensors at a predetermined cycle in synchronism of lighting of the light sources. The wavelengths of the light sources are preferably 480 nm, 545 nm, and 640 nm or their vicinities. Information of the image is read out as serial electrical signals corresponding to the respective wavelengths.
