Abstract
The invention is relates to a simple, inexpensive high capacity output catch tray for copiers and other document production machines. The output tray automatically increases in capacity as the stack of copies in it accumulates, without external power source or control, while maintaining a relatively constant elevation relative to the copier output port, and automatically returns to its original position when partially or completely unloaded.
Claims13
A high capacity output catch tray apparatus for accepting an output of a document production apparatus, the catch tray apparatus comprising:
- a rectangular sheet support member, the sheet support member being the size of a sheet of paper and capable of supporting a plurality of the sheets from the output;
- a frame element defining an opening the size of a sheet of paper, the frame element comprising rectangular dimensions that may be varied according to dimensions of the output, the frame element being capable of being coupled to the document production apparatus so that the sheet support member catches the output of the document production apparatus;
- and
- a biasing element comprising a proximal biasing element end and a distal biasing element end, the proximal biasing end being coupled to the frame element and the distal biasing element end being coupled to the sheet support member, wherein the biasing element is responsive to a weight of the plurality of sheets supported by the sheet support member such that the sheet support member is displaced downward effective to maintain an elevation of a top sheet of the plurality of sheets in a desired range relative to the output.
