Abstract
PURPOSE: To make it possible to increase the copying speed and the resolution, as compared with the conventional method, by setting a plurality of optical fibers into a main scanning line.
CONSTITUTION: The laser flux of light A from a laser source 3 is periodically deflected by a rotary polygonal mirror 5, and a cylindrical lens 7 is used so that the original O upon its carriage 1 is condensed for main scanning purposes in the direction of arrow P into a slit shape which has a small length and a very small width. The original carriage 1 is auxiliary scanned in the direction of arrow T by a rack 1a and a pinion 2. A condensing array 9 of optical transmitting elements are arranged with respect to the band-shaped locus of the condensing portion in the main scanning direction so that the optical image is received while arranging in contact the optical transmitting members 8 made of five optical fibers and converted into electric signals by means of light receiving elements 9a which are arranged at the emanating end faces. The respective electric signals are fed to semiconductor laser arrays 10 arranged so that they are modulated in intensity into a laser beam B. This beam B is introduced into the polygonal mirror 5 so that the reflected light is used to expose a photosensitive drum 22 through a condensing lens 21 to form an electrostatic latent image corresponding to the original, thus obtaining the copies by a normal process.
