Abstract

In a document imaging apparatus in which documents are fed to an imaging station and then fed to a documents catch tray system for automatic document restacking, there is provided a common, shared, restacking catch tray receiving either cut sheet documents or computer form (CF) web documents at the upper surface of the imaging apparatus, rather than dropping the CF web down to a tray below the end of the apparatus. This dual mode restacking catch tray is pivotable from a first position at a generally horizontal tray angle for restacking cut sheet documents into a second position at a preferred angle for fan-folding a computer form web. There is also an upper baffle unit partially overlying the output path to the restacking area, which is pivotable between a first position for planarly guiding cut sheet documents, and a second, raised, position for guiding a computer form web arcuately and then downwardly into the restacking area with an integral CF guide baffle. This upper baffle unit desirably includes an integral gate which automatically selectively gates documents onto two different paths segments, below or over the guide baffle, which gate may be provided by one end of the guide baffle.

Claims

1. In a document imaging apparatus in which both conventional cut sheet documents and computer form web fan-folded documents are fed to an imaging station accessible at the upper surface of said imaging apparatus and then said documents are fed in an output path from said imaging station to a documents catch tray system for automatic document restacking, the improvement in said documents catch tray system comprising:

a common shared restacking catch tray area adapted to receive both cut sheet documents and computer form web fan-folded documents,

said common shared restacking catch tray area being adjacent said imaging station at the upper surface of said imaging apparatus,

said common shared restacking catch tray area being pivotable between a first position at a preferred tray angle for restacking cut sheet documents thereon and a second position at a different preferred angle for fan-fold restacking of a computer form web thereon;

and an upper baffle unit at least partially overlying said output path from said imaging station to said restacking catch tray area,

said upper baffle unit being pivotable between a first position for guiding cut sheet documents into said restacking catch tray area for stacking, and a second, raised, position for guiding a computer form web arcuately into said restacking catch tray area for fan-fold restacking.

2. The documents catch tray system of claim 1 wherein said upper baffle unit in said second position provides a said output path which arcuately guides a computer form web document up above the level of said common restacking catch tray area and then downwardly towards said restacking catch tray area.

3. The documents catch tray system of claim 1 wherein said upper baffle unit has an integral baffle guide and provides two different alternative, output path segments request;

a first, substantially linear, output path under said baffle guide for guiding cut sheet documents into said restacking catch tray area in said first position of said upper baffle unit, and a second, arcuate, output path segment over said baffle guide for arcuately guiding computer form web documents into said restacking catch tray area in said second position of said upper baffle unit.

4. The documents catch tray system of claim 2, wherein said upper baffle unit has an integral baffle guide and alternatively provides two different segments of said output path;

a first output path segment under said baffle guide for guiding cut sheet documents into said restacking catch tray area in said first position of said upper baffle unit, and a second, arcuate, output path segment over and above said baffle guide for guiding computer form web documents into said restacking catch tray area in said second position of said upper baffle unit.

5. The documents catch tray system of claim 3, wherein said upper baffle unit includes an integral gate which is automatically pivoted to automatically selectively gate documents into said respective first or second output paths segments below or over said baffle guide when said upper baffle unit is pivoted between said first and second positions.

6. The documents catch tray system of claim 5, wherein said integral gate comprises an end of said baffle guide adjacent said imaging station which is moved above or below said output path therefrom when said upper baffle unit is pivoted between said first and second positions.

7. The documents catch tray system of claim 1, further including edge guide means for assisting computer form web restacking, which edge guide means is automatically raised into its operative position when said said restacking catch tray area is pivoted into said second position for fan-fold restacking of a computer form web document thereon.

8. The documents catch tray system of claim 7, wherein said upper baffle unit in said second position provides a major portion of said output path which arcuately guides a computer form web document up above the level of said common restacking catch tray area and then downwardly towards said restacking catch tray area adjacent said edge guide means.

9. The documents catch tray system of claim 1 wherein said upper baffle unit in said second position provides an output path for the computer form web fan-folded documents which provides a stopping position for the web with a fan-fold exited from said upper baffle unit but substantially above said restacking catch tray area.

10. The documents catch tray system of claim 9, wherein said feeding of computer form web documents to said imaging station is incremental with variable stopping positions of said computer form web such that said incremental stopping positions accommodate different distances between said fan-folds of a said computer form web.

11. The documents catch tray system of claim 9, wherein said stopping position is a variable function of the amount of computer form web document previously fed to said restacking catch tray area.

12. The documents catch tray system of claim 1, wherein said restacking catch tray area preferred tray angle is between approximately 15 and 17 degrees from the horizontal.
