ABSTRACT:
An electrophotographic copying apparatus designed to make successive copies from a stack of original documents, automatically, is disclosed herein. To this end, the apparatus utilizes a feeding arrangement configured to act on the stack in a way which successively moves each document onto the copying platen from the bottom of the stack when the latter is placed in a feed tray forming part of the overall arrangement, and thereafter back onto the top of the stack within the tray along a looped path of movement from the tray to the platen and back to the tray. The copying apparatus also includes an assembly located to one side of the feed tray for detecting when the last document in the stack has moved from the tray to the copying platen.
