ABSTRACT:
A document feed mechanism for a copier machine incorporating an automatic document feed (ADF) with a semi-automatic document feed (SADF) and enabling the SADF to interrupt the ADF. The ADF tray upon which a stack of documents to be copied is placed is situated directly above the viewing station. A wave generator (shingler) paper feed means fans out the topmost sheets on the stack and up a ramp until the topmost sheet enters closed nip rollers. The nip rollers, together with aligner rollers and a drive belt, move the sheet around a substantially 180.degree. bend and onto the viewing station. Second sheet feeds are prevented by a restraint pad positioned between the nip rollers and the exit of the ramp, the top of the restraint pad being above the nip of the nip rollers so that the topmost sheet presses a second sheet downwardly into the restraint pad. The SADF feeds sheets onto the viewing station using the aligner rolls and the drive belt.
