ABSTRACT:
A document feeder for automatically inverting a duplexed original so that the second side may be copied. The inverting mechanism is a turnaround roll located at the exit of the copy station. The inverting mechanism cooperates with rollers located above the document glass for moving documents thereacross. The rollers are inclined at an angle to the direction of paper movement in order to position paper against a side reference edge. When receiving a document from the turnaround roll and moving it in the reverse direction, the inclination of the rollers is removed or altered to a minus angle. Alternatively, a second set of rollers, inclined at a minus angle, are brought into active use when documents are moved in the reverse direction.
