ABSTRACT:
An automatic document handling system for copying documents in a pre-collated recirculation manner with minimal document handling to provide pre-collated output copy sets. The documents may be loaded manually in a cassette unit removed from a xerographic copier. The cassette unit comprises two document retaining webs commonly wound on two scrolls. The documents are retained on a first web at all times. The second web separates from the first web only in the optical imaging area so as to allow unobstructed exposure of the documents. The second web separates by forming a loop around the scrolls from separating rollers at opposite sides of the imaging area, and winds up on one scroll as it is unwound from the other scroll. Positive document retention is provided by the second web even though the first web is outside wound.
