ABSTRACT:
A multi-functional laser printer capable of executing both the printing operation and the manuscript readout operation with one unit. The laser printer comprises a printing unit for splitting a laser beam generated from a laser into a picture forming beam and a manuscript reading-out beam by a beam splitter, and a manuscript readout unit for reading out the content of the manuscript by scanning the manuscript reading-out beam on the manuscript. The printing unit and the manuscript readout unit commony have a double-structured hologram disk for diffracting and scanning the splitted beams. The double-structured hologram disk comprises picture forming holograms formed on the outer peripheral surface thereof and manuscript reading-out holograms formed on the interior thereof.
