Sheet Receiving Tray

A sheet receiving tray stacks sheets sequentially received thereby and includes a pivoting wire guide, which decelerates entering sheets and controls the stacking thereof on the tray.

Sheets 11 are ejected to the sheet receiving tray by drive rolls 13 and 15. These drive rolls may be staggered with respect to one another to provide a bow in the sheet 11 in the direction of its travel, thereby giving the sheet additional beam strength. As the sheet 11 progresses past the drive rolls, it strikes wire guide 17 which is freely pivoted on cover member 19. With reference to Figs. 2- 4, the exiting sheet deflects guide 17 upward thereby storing potential energy in the guide. The guide 17 then starts falling due to gravity, until it rests on top of the sheet 11 which is positioned on pivoting tray member 21. Fig. 5 depicts the shape of wire guide 17.

Pivoting tray member 21, upon which sheets 11 come to rest, pivots about hinge spring 23 in a downward direction against the force exerted thereon by the leaf spring 25 as the number of sheets stacked on the tray 21 increases. Sheets are thus trapped between the tray 21 and the guide 17, thereby keeping the sheets 11 from curling.
