Paper Feed

Throughput is increased by providing independently operable front and rear feed rollers. A new sheet can be inserted to the rear feed roller while the present sheet is being printed.

Paper table 1 is pivotable about point 17 and has rear feed roller 14 connected about its lower end. With the components positioned as shown, sheet 6 is in a position for printing. Sheet 6 is maintained in engagement with platen 10 by front feed roller 16 and paper bail roller 8 connected to paper bail arm 9. Sheet 6 is fed between hood 7 and filter 21 during printing.

Paper table 1 has a corrugated surface for facilitating the stacking of a second sheet 2, such that sheet 2 can follow sheet 1 and be positioned about platen 10. As sheet 6 continues to be fed through the opening between hood 7 and filter 21, edge 22 of sheet 2 will eventually come in contact with surface 19 of paper gate 5. Paper gate 5 is pivotable about point 23. Sheet 6 is also maintained in contact with platen 10 by edge 20 of paper gate 5.

During initial loading of the typewriter, a force is applied to the upper portion of paper table 1 in the left direction and paper gate 5 is brought out of contact with platen 10. When this occurs, latch arm 24 is in the position shown in engagement with armature 18.

Armature 18 forms part of the magnet/armature arrangement including magnet 12. Latch arm 24 is maintained in contact with armature 18 under the influence of spring 13.

When paper table 1 is restored to t...
