ABSTRACT:
A paper feeder including a sucker frame, a separation suction device mounted on the sucker frame and substantially vertically movable for picking up stacked sheets one at a time, and a transport suction device mounted on the sucker frame and substantially horizontally movable for transferring the picked-up sheet from the separation suction device. The separation suction device includes a hollow guide nozzle supported on the sucker frame and tiltable in a back-and-forth direction and an orthogonal direction, a hollow intermediate nozzle telescopically fitted over the guide nozzle and resiliently urged to move downwardly, the hollow intermediate nozzle having a flange, a hollow suction nozzle telescopically fitted over the intermediate nozzle and resiliently urged to move downwardly, the hollow suction nozzle being operatively coupled to the intermediate nozzle and including a bottom having a suction port, an adjusting mechanism interposed between the sucker frame and the guide nozzle for tilting the guide nozzle to adjust angles of inclination thereof in the back-and-forth and orthogonal directions, a guide member vertically movably supported on the sucker frame and vertically restricting the flange of the intermediate nozzle, and a cam mechanism mounted on the sucker frame and operable in synchronization with the separation and transport suction devices, the guide member being limited in its vertical position by the cam mechanism.
