ABSTRACT:
A bottom level sheet feeding apparatus having a tray for receiving a stack of sheets, a driven endless belt conveyor with an upstream end extending into the tray, a lead surface plate over a fixed-height idler roller to form a pinch point between the belt conveyor and the lower edge of the lead surface plate, a retard strip, and a pair of puller rolls for transporting fed sheets from the extreme downstream end of the belt conveyor to an appropriate copying mechanism. Both the upstream end of the belt conveyor and the downstream end of the belt conveyor may be lowered and raised relative to the fixed height idler roller. A solenoid or hydraulic piston arrangement is disclosed for lowering or raising the upstream and downstream ends of the belt conveyor.
