Abstract
PURPOSE: To secure a proper picture formation through an independent scan, by disposing in opposition to each other the original platen surface and the original read scanning surface to obtain the video signal, setting the original on both the scanning and original platen surfaces each and then avoiding a mutual optical interference between the both surfaces.
CONSTITUTION: The original O on the original platen surface 2 is illuminated by the illuminating light source 3 and then exposed on the electrostatic drum 9 by the mirrors 5, 7 and 8, lens 6 and others. A scanning surface is provided in opposition to the surface 2, and the original on the scanning surface is illuminated by the light source 14 to be converted into the video signal by the mirrors 15W17, lens 18 plus solid image sensor 19 each. The video signal is supplied to the laser beam scanning mechanism 10 and then converted into the prescribed laser beam there to be exposed onto the drum through the semitransmissible mirror. For illumination by the light sources 3 and 14, the scanning is carried out by giving a slight shift between the original platen surface and the scanning surface to avoid the mutual optical interference.
