A pivoting paper path in a Top Active Retard Feeder consists of a rotatable inlet baffle that turns in unison with a corresponding nudger roll. A schematic representation of the basic configuration is shown in the Figure. When a tray surface 26 is loaded with a maximum capacity of documents 28, a nudger roll 12 is lowered, in the direction of the arrow 14, to a feed position at the top of the stack. A lower baMe 24, likewise is positioned to provide a lead in paper path to drive roll 16 and retard roll 22, which are followed by a plurality of take away rolls 20. As the stack height of documents 28 decreases, the lower baffle 24 pivots about point 18 along with the nudger roll 12, maintaining the paper path inclusive of the nip formed by the drive roll 16 and the retard roll 22. This action eliminates the need for an elevator in the tray and a solenoid actuated loading gate presently used in other types of Automatic Document Handler feeder applications.
