Abstract
Abstract A copier is disclosed as having a sorter positioned on top of the copier housing for easy access to an operator. The path of movement of processed copy sheets is repeatedly folded in order to present to the operator collated copy sets or stacks for easy observation of sorting and removal. The sheets exit the copier processing station in a horizontal plane, are turned 90° while still in the plane, are transported upwardly in a vertical plane, and deposited in sorter trays toward the operator.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
281 words
A copier having copy sheet processing stations arranged to produce copy sheets along a processing path with one of their long edges being the leading edge thereof, comprising: means for orienting each copy sheet exiting from the processing horizontal plane and in a direction toward one side of the copier, first means in said path of movement for changing the direction of movement of the copy sheets approximately 90° and to transport the sheets toward the rear end of the copier while in said generally horizontal plane, second means for changing direction of movement of copy sheets from the generally horizontal plane upwardly in a generally vertical plane, a sorter having a plurality of vertically stacked sheet collecting trays positioned adjacent said rear end of the copier, and having sheet unloading portions projecting toward the front end of the copier and sheet loading openings toward the rear of the copier, and transport means arranged between said second means and said sheet openings for conveying sheets from second means to said trays during a copying/sorting run, so that said copy sheets are desirably so processed in said copier in the direction of movement of the shortest dimensions of said copy sheets, and then are rotated and transversely stacked in said sorter overlying said copier, over an area of the rear of said copier, within the perimeter of the horizontal dimensions of said copier per se, with the longest dimensions of said copy sheets extending along the rear of said copier and the shortest dimensions of said copy sheets extending partially towards the front of said copier, to provide a highly compact integral copier/sorter yet convenient front unloading of the sorted copy sheets.
Claim 2
Dependent Claim
281 words
A copier having copy sheet processing stations arranged to produce copy sheets along a processing path with one of their long edges being the leading edge thereof, comprising: means for orienting each copy sheet exiting from the processing horizontal plane and in a direction toward one side of the copier, first means in said path of movement for changing the direction of movement of the copy sheets approximately 90° and to transport the sheets toward the rear end of the copier while in said generally horizontal plane, second means for changing direction of movement of copy sheets from the generally horizontal plane upwardly in a generally vertical plane, a sorter having a plurality of vertically stacked sheet collecting trays positioned adjacent said rear end of the copier, and having sheet unloading portions projecting toward the front end of the copier and sheet loading openings toward the rear of the copier, and transport means arranged between said second means and said sheet openings for conveying sheets from second means to said trays during a copying/sorting run, so that said copy sheets are desirably so processed in said copier in the direction of movement of the shortest dimensions of said copy sheets, and then are rotated and transversely stacked in said sorter overlying said copier, over an area of the rear of said copier, within the perimeter of the horizontal dimensions of said copier per se, with the longest dimensions of said copy sheets extending along the rear of said copier and the shortest dimensions of said copy sheets extending partially towards the front of said copier, to provide a highly compact integral copier/sorter yet convenient front unloading of the sorted copy sheets.
Claim 3
Dependent Claim
23 words
The copier of claim 1 wherein said generally horizontal plane is positioned adjacent the top of the copier between the side ends thereof.
Claim 4
Dependent Claim
17 words
The copier of claim 1 wherein said collecting trays are positioned vertically above said generally horizontal plane.
Claim 5
Dependent Claim
271 words
A copier being defined by side ends, a rear end and a front end, and having copy sheet processing stations arranged to produce copy sheets along a processing path with one of the long edges of the sheets being the leading edge thereof, comprising: means for orienting each copy sheet exiting from the processing stations after processing thereof to a path of movement in a direction toward one side end of the copier, means in said path of movement for changing the direction of movement of the copy sheets approximately 90° and to transport the sheets toward the rear end of the copier, means for changing direction of movement of copy sheets upwardly in a generally vertical plane, a sorter having a plurality of vertically stacked sheet collecting trays positioned adjacent said rear end of the copier, and having sheet unloading portions projecting toward the front end of the copier, and transport means for conveying sheets to said sorting trays during a copying sorting run, so that said copy sheets are desirably so processed in said copier in the direction of movement of the shortest dimensions of said copy sheets, and then are rotated and transversely stacked in said sorter overlying said copier, over an area of the rear of said copier, within the perimeter of the horizontal dimensions of said copier per se, with the longest dimensions of said copy sheets extending along the rear of said copier and the shortest dimensions of said copy sheets extending partially towards the front of said copier, to provide a highly compact integral copier/sorter yet convenient front unloading of the sorted copy sheets.
Claim 6
Dependent Claim
