ABSTRACT:
An electrophotographic copying apparatus includes a photosensitive surface capable of retaining an electrostatic latent image for at least two cycles of the surface so a first copy of an original can be made upon scanning the original and the latent image can be recycled to produce a second copy of the same original during the return of the scanning mechanism. The apparatus includes an improved mechanism for driving the scanning mechanism, as well as improved developing and transfer stations. The improved scanning mechanism includes a movable carriage having a vertical slotway. A pin is held within the slotway and driven by a flexible cable to travel in an endless path to move the carriage back and forth beneath the original. The carriage may include a second slotway for holding a second pin driven by a flexible cable arranged in an endless path extending a distance longer than the first mentioned path. Either of these pins may be engaged to its slotway to vary the length of travel of the carriage.
