Abstract

This copier exit tray reliably stacks a variety of sizes of copy paper. As paper exits the copier (not shown), it enters aligner 10, while moving in the direction generally indicated by arrow 11. The aligner operates to align the sheet's left-hand edge (as seen in the top view of Fig. 1) to stationary reference edge 12. After alignment, the sheets are driven by transport drive nip 13, 14 (Fig. 3), into exit pocket 15.

Copier Exit Tray

This copier exit tray reliably stacks a variety of sizes of copy paper. As paper exits the copier (not shown), it enters aligner 10, while moving in the direction generally indicated by arrow 11. The aligner operates to align the sheet's left- hand edge (as seen in the top view of Fig. 1) to stationary reference edge 12. After alignment, the sheets are driven by transport drive nip 13, 14 (Fig. 3), into exit pocket 15.

The bottom wall of the exit pocket is spring-biased upward, and lowers as the pocket fills. This can be seen by a comparison of Figs. 4 and 5.

Once the sheets are resident in the exit pocket, they are held down by rigid hold-down bails 16. The rightmost one of these bails (as seen in the top view of Fig. 2) is nonpivotally attached to rod 17, whereas the other two bails freely pivot on this rod. As the exit pocket fills, the above-mentioned rightmost bail causes rod 17 to rotate, and eventually switch 18 is operated to indicate a full exit pocket.

A sheet deflector 20 is positioned in accordance with the size of paper currently being fed. This deflector is position controlled, in accordance with sheet size, by actuator 21 (Fig. 2).

Fig. 3 shows the position of deflector 20 for smaller size sheets. In this position, drive nip 13, 14 imparts enough kinetic energy to the smaller sheets such that they pass between the upper surface of deflector 20 and wire guides
22. During their travel to the exit pocket, these smaller sheets physical...
