ABSTRACT:
A paper sheet guide mechanism is provided for use in a sorter of the elevator type. Paper sheets are conveyed from an input through the paper sorter along a conveyor belt and are successively deflected by an elevator for distribution on corresponding paper shelves. A guide mechanism includes a plurality of moveable wires which on one end are attached to the elevator and extend parallel to each other along a common plane toward the top of the sorter. These moveable wires pass over a plurality of pulleys and are thereby directed down a common side of the housing, around other pulleys, and are attached to a bracket that is connected to the bottom of the elevator in an endless loop. A tension spring is interposed in each of these wire loops. The plane formed by the parallel moveable wires is adjacent to and slightly closer to the inner ends of the paper shelves than is the plane along which paper is transported through the sorter by the conveyor belt. A plurality of fixed wires are disposed opposite the endless loop wires, and on the other side of the paper transport plane. Paper sheets are conveyed by the sorter conveyor belt between the fixed and the endless loop wires and are delivered to the appropriate paper shelves by the elevator as it moves up and down in the sorter housing.
