ABSTRACT:
In the present invention, a sheet-sorter, operating in conjunction with a photocopy machine, has a plurality of trays in general horizontal alignment with the path taken by a sheet of paper discharged from the copier. A tray pusher is arranged to move the lower-most tray in a stack of trays disposed above the paper-path so that the in-board end of the lower-most tray will drop some distance below the paper path, after the sheet has been discharged from the copier. The tray-pusher may be activated by movement of the copier carriage or by an appropriate gear-train connection to a pair of juxtaposed rolls, slightly spaced from each other, constructed and arranged so that one roll will cause the other roll to rotate only when a sheet of paper is disposed between the rolls as the sheet is discharged from the copier. The stack of trays may be re-set manually or by the movement of the copier carriage.
