ABSTRACT:
Apparatus for flipping document sheets such as paper or the like from one side to the other such that the document sheets may be stacked in a hopper in sequenced order after printing or copying on one side or used for printing or copying on both sides. The apparatus includes at least one rotatable cylindrical member having tapered slots disposed therein 180 degrees apart for receiving the leading edge of the sheet to be flipped, and a clamping member which permits the slots to remain open during the sheet insertion, clamp the sheet during rotation of the cylindrical member, and again permits the slots to open at the release point such that the flipped sheet may be released. The location and angle of the slots in the cylindrical member are such the initial force for rotating the cylindrical member is imparted thereto by the entry of document sheet into the slot.
