发明名称 Document air valve
摘要 A header member containing an air chamber is positioned above each pocket of a document sorter, the air chamber having an upwardly directed inlet port and a plurality of downwardly directed outlet ports downstream of the inlet port. An air supply nozzle is positioned below the inlet port to blow air into the air chamber, the air then flowing out of the chamber through the outlet ports. The supply of air into the chamber is interrupted when a document passes between the inlet port and the supply nozzle, and the air flow is resumed when the document passes the inlet port, the air flowing from the outlet ports blowing the document downwardly, out of the path of the succeeding document, and into the pocket of the document sorter.
