Abstract
An intensity of light emitted from a lamp is passed through a mirror tunnel and is directed to a disk which comprises three, B, G, and R, color filters, each extending 120 degrees on the disk. Each of the B, G, and R modes of light, separated on the disk, is guided through the optical fiber bundle and is transmitted to the PLZT elements. A pattern of the PLZT elements, determined by a group of dots of exposure data to be printed, are energized by a given voltage in synchronization with the rotation of the disk 13, thus allowing a desired mode or wavelength of light to pass selectively and fall efficiently on the printing paper.
