Abstract
A plurality of light emitting elements which are adapted to emit light of three primary colors are activated in a sequential order, and the emitted light is transmitted through a single emission side optical fiber to illuminate an image surface. Reflected light from the image surface is conveyed to a light receiving element through a corresponding receiving side optical fiber. A decision circuit determines whether or not an output from the light receiving element has reached a given level. The sequence of emission from the respective light emitting elements as well as the amount of light emitted therefrom are controlled by control means. When the given level is reached, the associated data is stored to assure a proper reading of the image.
