Abstract

The multisheet output copy sets issuing from a xerographic copier are vertically stacked one on top of the other, in offset fashion. An output drawer oscillates horizontally back and forth, in synchronism with arrival of the sets, in order to produce this offset. An access door covers the oscillating drawer during copying. An actuating handle on this access door operates to simultaneously uncouple the drawer from the copier's oscillating mechanism, and to couple the drawer to the access door, so that the drawer may then be drawn out of the copier for manual unloading of the offset copy sets.

Offsetting Copier Output

The multisheet output copy sets issuing from a xerographic copier are vertically stacked one on top of the other, in offset fashion. An output drawer oscillates horizontally back and forth, in synchronism with arrival of the sets, in order to produce this offset. An access door covers the oscillating drawer during copying.

An actuating handle on this access door operates to simultaneously uncouple the drawer from the copier's oscillating mechanism, and to couple the drawer to the access door, so that the drawer may then be drawn out of the copier for manual unloading of the offset copy sets.

The figure is a right-hand side view of copy set drawer 10. This drawer is supported for horizontal movement, as indicated by arrow 11. As a result, copy output sets are vertically stacked, one on top of the other. Line 12 is the vertical edge of one stack of sets, and line 13 is the vertical edge of the offset stack of sets.

Drawer 10 includes a vertically downward extending tab 14 and a horizontally extending pin 15. A link 16 includes a notch 17 which releasably captures pin 15. The right-hand end of link 16 is pivotally connected to disc 18. This disc rotates clockwise about horizontal axis 19. As a result, link 16, pin 15 and drawer 10 move horizontally back and forth, as indicated by arrow 11.

The rotation of disc 18 is not continuous, but is rather in 180? steps. These steps are synchronized with arrival of copy sets at drawer 10. In this manner, one set is stacked with its left-hand edge at 12, and the next set is stacked with its left-hand edge at 13.

Drawer 10 is covered to outside view by copier access door 20. As shown, door 20 is held in place on the copier frame by permanent magnets, such as 21 and 22. Door 20 is opened by pulling its handle 24 horizontally to the left. This door is not pivoted, but rather, moves in the manner...
