Abstract

When a multipage document is copied on some copiers, the sequence of the copies at the output is reversed from that at the input. The disclosed sheet reverser provides a low cost attachment to solve this problem, by turning each copy upside down and over as it is delivered from the copier.

Copied Sheet Sequence Reverser

When a multipage document is copied on some copiers, the sequence of the copies at the output is reversed from that at the input. The disclosed sheet reverser provides a low cost attachment to solve this problem, by turning each copy upside down and over as it is delivered from the copier.

As shown above, the device consists of a bin adapted to be connected to the output bin of a copier, and a document feed path comprising a plurality of pairs of feed rollers and sheet guides. Power to drive the rollers is taken from the delivery rollers of the copier. Another embodiment (not shown) includes a separate motor adapted to drive the reverser feed rollers in synchronism with the copier delivery rollers.

Referring to the figure, as a sheet emerges from the copier, it passes between the pair of delivery rollers 2 and 3. Sheet deflector 4 guides the sheet to the nip between rolls 6 and 7 which urges it beneath guide plate 8 to the pair of rolls 9 and 10 from which the sheet passes it to bin 12. The device is also equipped with a means for sensing when the bin 12 is full. Sensor arm 13 is adapted to pivot about point 14 when the bin is full. The other end 13' of sensor arm 13 presses against the full bin sense arm 15 of the copier.

Thus, as sheets are fed out from the copier, they are guided into the feed roll arrangement of the reverser mechanism, where the leading edge passes through a 180 degrees change in direction so that the top of the...
