Abstract

The figure illustrates the overall configuration of a small compact copier wherein the paper supply tray and the copy sheet exit tray are combined into one unit which is entirely contained within the machine. In addition, the configuration includes both a moving platen and moving optical system as well as a moving photoreceptor belt to enable the platen to be limited in movement to the maximum dimension of the copier, never extending beyond the perimeter while the additional scanning distance is achieved with the moving optics.

The figure illustrates the overall configuration of a small compact copier wherein the paper supply tray and the copy sheet exit tray are combined into one unit which is entirely contained within the machine. In addition, the configuration includes both a moving platen and moving optical system as well as a moving photoreceptor belt to enable the platen to be limited in movement to the maximum dimension of the copier, never extending beyond the perimeter while the additional scanning distance is achieved with the moving optics.

An original document to be copied is placed on a moving platen 10. During imaging the scanning platen 10 moves to the left while the scanning optics carriage 12 is moved to the right and the photoreceptor belt 14 moves counterclockwise around support and drive rollers 18, 20, 22. The optical carriage contains a charge corotron 24, illuminator 36, reflector 28, mirror 32 and selfoc lens which operates in the conventional way. Following charging of the photoreceptor and exposure in the conventional way the image is developed at development station 36 with, for example, single component magnetic brush develoFment. In the two cycle system as the photoreceptor with the developed image in it once again moves in the
