Abstract
PURPOSE: To obtain the video signal which scans the original on each surface and then modulates the exposed optical image and the projected beam, by disposing in opposition to each other the surface of the original platen to be copied through projection and the original platen surface to obtain the video signal.
CONSTITUTION: The original O which is is irradiated by the illuminating light source 3 and then exposed on the electrostatic photosensitive drum 9 by the mirrors 5, 7 and 8, lens 6 and others is put on the transparent platen plate 2. A light masking plate is put on the original, and another original is put on the light masking plate. The original on the light masking plate is illuminated by the light source 14 and then irradiated onto the solid state image sensor 19 and others via the mirrors 15W17 plus lens 18 each to be extracted as the video signal. This video signal is supplied to the laser beam scanning mechanism 10 and then emitted from the mechanism 10 in the form of the laser beam to be irradiated on the electrostatic drum via the semitransmissible mirror 8.
