Abstract
A low cost, paper feeder for large copy sheets includes a media chamber mounted to support copy sheets in a substantially vertical plane. A two-position, T-shaped feeder mechanism including a pair of one-way clutch controlled feed rolls is slidably mounted on a rail for contacting the media. A foot pedal is connected to the feeder mechanism such that when movement of the foot pedal is initiated, the feeder mechanism is moved in a first direction to a position contacting the copy sheets and with continued movement of the foot pedal, a top sheet of the copy sheets is moved by the feeder mechanism out of the tray in a second direction a predetermined amount to a copier wait station, and with return of the foot pedal to its initial position, the feed mechanism is caused to retract from the surface copy sheets in a third direction to its initial position.
