Abstract

It is known to use an inverting device in a xerographic copier/duplicator in order to permit double-sided copying by changing the motion of a paper sheet from a ffhead-first" to "tail-firsttt mode. This disclosure represents a simplified configuration for an inverter having only a few parts and featuring low cost with high operating reliability.

SINGLE ROLL, SNAP OVER INVERTER (Cont'd)

It is known to use an inverting device in a xerographic copier/duplicator in order to permit double-sided copying by changing the motion of a paper sheet from a ffhead-first" to "tail-firsttt mode. This disclosure represents a simplified configuration for an inverter having only a few parts and featuring low cost with high operating reliability.

In the figure, paper sheet guide plates 1, 2, 3, 4 define the limits of paper travel. Roller 5 contacts both plates 1 and 2, and turns in the direction shown by the arrow thereon. Paper sheets enter the inverter in the direction shown by arrow 6 and leave after inversion in the direction shown by arrow 7. As the leading edge of the entering sheet enters the nip of retard roller 8, its trailing edge snaps past the centerline of roller 5 and becomes the leading edge as it exits the inverter, driven by the pressure between roller 5 and guide plate 2.
