Abstract
The invention provides an improved auger conveyor in the magazine section of a document feeder apparatus which is capable of feeding large amounts of documents to a document sorting machine in a rapid and efficient manner. The auger conveyor includes: three horizontal augers which rotate in a clockwise direction; spiral grooves formed on the horizontal augers and divided in half by the existence of two separate pitches; joggers on the surfaces of the wider pitched portions of the two inner horizontal augers which facilitate reception of documents within the grooves; a raised auger which rotates in a counterclockwise direction; and a spiral groove configured in the direction opposite to the grooves on the horizontal augers and which also is divided in half by the existence of two separate pitches; and a document feed or pickoff apparatus for individually separating the lead document from the document supply. The improved auger conveyor efficiently conveys the documents in the proper orientation while assuring that they are separated from one another for individual processing.
