Abstract

The document guide is arranged to sense document jams and provides easy removal of jammed documents from the document path. Documents are advanced through the document path by document transport belt 3. This moves in the direction indicated by the arrow. The documents are maintained in contact with belt 3 via a stacker or driver roll 5, cooperating with biased idler roll 7. The document guide comprises lower guide plate 9 which is maintained in a relatively fixed position. Docu-moving through the system slide over plate 9 as the result of the friction between 3, the documents and the driver stacker roll. Upper guide plate 11 is also provided. Plate 11 is hinged by hinge 13 to main frame 15 of the machine.

Jam Sensing Document Guide

The document guide is arranged to sense document jams and provides easy removal of jammed documents from the document path. Documents are advanced through the document path by document transport belt 3. This moves in the direction indicated by the arrow. The documents are maintained in contact with belt 3 via a stacker or driver roll 5, cooperating with biased idler roll 7. The document guide comprises lower guide plate 9 which is maintained in a relatively fixed position. Docu-moving through the system slide over plate 9 as the result of the friction between 3, the documents and the driver stacker roll. Upper guide plate 11 is also provided. Plate 11 is hinged by hinge 13 to main frame 15 of the machine.

Plate 17 has an auxiliary plate 17 fixed to it having tab 19. When 11 is swung upwardly, tab 19 engages the end of roll 7 and also moves it in an upward direction against the force of the roll 7 biasing spring not shown. The normal spacing or distance of plate 11 from plate 9 is adjusted by bracket 21 attached to plate 11 and cooperating with adjusting screw and nut 23 mounted in fixed bracket 25 which is attached to frame 15. Switch operating finger or extension 27 extends rearwardly through frame 15 and operates the plunger of electrical switch 29. When plate 11 is in its normal position, with the proper spacing as determined by adjustment 23, finger 27 causes switch 29 to assume a particular contact condition.
