Abstract
In a photoreceptor method and assembly for a photocopy apparatus of the type employing a flexible endless photoreceptor belt, a shuttle mechanism is located between the imaging and processing stations of the photocopy apparatus which simultaneously stores and dispenses portions of the photoreceptor belt to enable the photoreceptor belt to be stopped at the imaging station during imaging and then rapidly removed from that station at high velocity after imaging is completed, while the velocity of the photoreceptor belt at the processing station may be maintained substantially constant.
Claims18
A photoreceptor system for a photocopy apparatus including flexible endless photoreceptor means, and drive means for driving said photoreceptor means through processing and imaging stations, wherein the improvement comprises in combination therewith
- velocity control means for controlling the velocity of said photoreceptor means such that the velocity thereof at said processing station is substantially constant and the velocity thereof at said imaging station may simultaneously be less than said substantially constant velocity,
- said velocity control means comprising means for simultaneously storing and dispensing portions of said photoreceptor means.
A method of photocopying comprising the steps of driving flexible endless photoreceptor means through imaging and processing stations of a photocopy apparatus,
- maintaining said photoreceptor means at a velocity less than a given velocity at said imaging station while transferring the image to be copied thereto,
- simultaneously moving said photoreceptor means at said given velocity through said processing station, and
- simultaneously storing and dispensing portions of said photoreceptor means.
