Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 222 words
In an electrophotographic copying apparatus, the improvement consisting of a supplemental paper feeding device for supplying sheets of recording paper, one by one to the copying apparatus, said device including a receiving table having vertically extending front and side walls, a lift having a platform and means raising and lowering said platform between said table and a position near the top of said walls, an open top container having side walls and a base having an opening therein substantially corresponding to the dimensions of said lift platform, a pallet positioned within said container for receiving stacked sheets of recording paper, means for positioning said container on said table within said vertically extending walls so that the opening in its base corresponds to the top of said platform, means for detachably holding said container on said receiving table including locking means for locking said container to said receiving table when said lift is in other than its lowermost position, whereby the raising or lowering of said lift raises and lowers said pallet and the papers supported thereon, feeding means positioned between the vertical side walls extending from said table for feeding papers from said device when said pallet and the papers supported thereon are raising into contact with said feeding means, and means in said copying apparatus for receiving the papers so fed.
Claim 2
Dependent Claim 222 words
In an electrophotographic copying apparatus, the improvement consisting of a supplemental paper feeding device for supplying sheets of recording paper, one by one to the copying apparatus, said device including a receiving table having vertically extending front and side walls, a lift having a platform and means raising and lowering said platform between said table and a position near the top of said walls, an open top container having side walls and a base having an opening therein substantially corresponding to the dimensions of said lift platform, a pallet positioned within said container for receiving stacked sheets of recording paper, means for positioning said container on said table within said vertically extending walls so that the opening in its base corresponds to the top of said platform, means for detachably holding said container on said receiving table including locking means for locking said container to said receiving table when said lift is in other than its lowermost position, whereby the raising or lowering of said lift raises and lowers said pallet and the papers supported thereon, feeding means positioned between the vertical side walls extending from said table for feeding papers from said device when said pallet and the papers supported thereon are raising into contact with said feeding means, and means in said copying apparatus for receiving the papers so fed.
