ELECTROPHOTOGRAPHIC APPARATUS COMPRISING IMPROVED IMAGING SYSTEM

摘要

One or more rows of focussing optical fibers are disposed between an original document carrier and a photoconductive member. An illumination lamp illuminates an original document on the carrier and the fibers focus an image of a linear portion of the document onto the photoconductive member. Relative movement between the document carrier, fibers and photoconductive member perpendicular to the row or rows of fibers is produced to scan the document. Aperture assembly is provided between the fibers and the photoconductive member defining an aperture wide enough that unevenness of the intensity of the image on the photoconductive member due to the individual fibers is eliminated. The intensity of the light image iscontrolled by means of a variable transformer or triac provided to the illumination lamp.
