Abstract
An illumination apparatus adapted for illuminating a subject with light comprises a plurality of fluorescent substances each having a different spectral characteristic, a drive device for repetitively locating the fluorescent substances at a predetermined position and a light source for illuminating the fluorescent substances. The illumination apparatus further includes a slit for focusing light on a subject to be illuminated. If the illumination apparatus is incorporated as a transfer section into a recording system such as a facsimile and a copying machine, since the fluorescent substances are alternately positioned at a predetermined location to illuminate a recording sheet, it is possible to obtain a clearly recorded image with high precision and at high speed.
