Abstract

A movable reference edge for a paper-stacking device will be described. It is especially useful on the exit ports of printers and copiers and provides off-set stacking by which the papers associated with subsequent jobs can be separated within a common output or exit tray.

Rotary Reference Edge for Off Set Stacking

A movable reference edge for a paper-stacking device will be described. It is especially useful on the exit ports of printers and copiers and provides off-set stacking by which the papers associated with subsequent jobs can be separated within a common output or exit tray.

Copiers, duplicators, printers, and other sheet-handling apparatus are usually provided at the output end with an aligner. The aligner transports the sheets at a bias, abutting them against a reference edge so that the sheets are aligned with respect to one another in the output tray. To offset one group of sheets from another, the reference edge can be made movable. The movable reference edge being described has the advantage of requiring only a small space, a simple operating mechanism, and minimum maintenance.

Fig. 1 is an illustration of the arrangement of the rotatable reference edge with respect to a paper transport and aligner at the output end of the above- described apparatus. The sheets enter the paper transport at the edge shown at the top of the figure and are biased by drive mechanisms (not shown) against the left-hand edge. The left-hand edge, against which the sheets are abutted, is provided by the rotary reference edge, as shown in Fig. 1.

Fig. 2 is a plan view of the rotary reference edge, showing a solenoid actuator as one example of a driving device. Fig. 2(A) illustrates the reference edge in a first or unenergized position. A shall...
