Abstract
Abstract A document copying system which is arranged to automatically collect copied paper sheets accommodated in a sorter in a classified state upon completion of the copying function for one original document group, and also to collect discharged original documents, capable of continuously effecting the copying operation including the classification work with respect to the plurality of original document groups, thus making it possible to realize an unattended copying operation over a long period of time.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
219 words
A document copying system including an automatic document feeder for feeding original documents placed on an original document tray onto an original document platform, and a sorter having a plurality of bins for accommodating therein, through classification, copied paper sheets discharged from a copy paper discharge section so as to effect a copying operation based on data written on a present data sheet disposed at a leading portion of each original document group, the improvement comprising: original document transport means for accommodating the original document discharged from the automatic document feeder into one of said plurality of bins of the sorter; and a document accumulating apparatus including, an accumulating plate and an accumulating tray movably disposed for vertical movement respectively at opposite sides of said bins, accumulating plate drive means and accumulating tray drive means for vertically displacing said accumulating plate and tray, and accumulating plate horizontal drive means for displacing said accumulating plate in a direction of said accumulating tray along the tray surface of each bin, said accumulating plate drive means, said accumulating tray drive means and said accumulating plate horizontal drive means being made effective upon completion of the copying function with respect to one original document group to thereby accumulate the original document and copied paper sheets accommodated in the sorter onto said accumulating tray.

Dependent Claim
219 words
A document copying system including an automatic document feeder for feeding original documents placed on an original document tray onto an original document platform, and a sorter having a plurality of bins for accommodating therein, through classification, copied paper sheets discharged from a copy paper discharge section so as to effect a copying operation based on data written on a present data sheet disposed at a leading portion of each original document group, the improvement comprising: original document transport means for accommodating the original document discharged from the automatic document feeder into one of said plurality of bins of the sorter; and a document accumulating apparatus including, an accumulating plate and an accumulating tray movably disposed for vertical movement respectively at opposite sides of said bins, accumulating plate drive means and accumulating tray drive means for vertically displacing said accumulating plate and tray, and accumulating plate horizontal drive means for displacing said accumulating plate in a direction of said accumulating tray along the tray surface of each bin, said accumulating plate drive means, said accumulating tray drive means and said accumulating plate horizontal drive means being made effective upon completion of the copying function with respect to one original document group to thereby accumulate the original document and copied paper sheets accommodated in the sorter onto said accumulating tray.
Claim 3
Dependent Claim
124 words
A document accumulating apparatus disposed in the vicinity of a sorter having a plurality of bins vertically arranged in an overlapping manner for accommodating therein through classification, paper sheets copied at a copying apparatus main body, comprising: an accumulating tray and an accumulating plate movably disposed respectively at opposite sides of said bins for vertical displacement; and accumulating plate horizontal displacing means for displacing said accumulating plate in a direction of said accumulating tray along the tray surface of each bin; said accumulating plate horizontal displacing means being provided with an accumulating plate displacing amount altering means for altering the displacing amount of said accumulating plate in the direction of said accumulating tray so as to be different from each other between neighboring bins.
Claim 4
Dependent Claim
124 words
A document accumulating apparatus disposed in the vicinity of a sorter having a plurality of bins vertically arranged in an overlapping manner for accommodating therein through classification, paper sheets copied at a copying apparatus main body, comprising: an accumulating tray and an accumulating plate movably disposed respectively at opposite sides of said bins for vertical displacement; and accumulating plate horizontal displacing means for displacing said accumulating plate in a direction of said accumulating tray along the tray surface of each bin; said accumulating plate horizontal displacing means being provided with an accumulating plate displacing amount altering means for altering the displacing amount of said accumulating plate in the direction of said accumulating tray so as to be different from each other between neighboring bins.
Claim 5
Dependent Claim
133 words
A document accumulating apparatus disposed adjacent to a sorter having a plurality of bins vertically arranged in an overlapping manner, comprising: an accumulating plate and an accumulating tray movably disposed respectively at opposite sides of said bins for vertical displacement, thereby collecting the documents accommodated in said bins by displacing said accumulating plate in a direction of said accumulating tray along the tray surface constituting said bin; document position detecting means for detecting the uppermost position of the documents accommodated in said accumulating tray; and accumulating tray displacing amount control means for controlling the displacing amount of the accumulating tray so as to maintain the tray surface of each bin and the uppermost position of said documents at a constant interval, based on the result of detection by said document position detecting means.
Claim 6
Dependent Claim
133 words
A document accumulating apparatus disposed adjacent to a sorter having a plurality of bins vertically arranged in an overlapping manner, comprising: an accumulating plate and an accumulating tray movably disposed respectively at opposite sides of said bins for vertical displacement, thereby collecting the documents accommodated in said bins by displacing said accumulating plate in a direction of said accumulating tray along the tray surface constituting said bin; document position detecting means for detecting the uppermost position of the documents accommodated in said accumulating tray; and accumulating tray displacing amount control means for controlling the displacing amount of the accumulating tray so as to maintain the tray surface of each bin and the uppermost position of said documents at a constant interval, based on the result of detection by said document position detecting means.
Claim 7
Dependent Claim
104 words
A document accumulating apparatus disposed adjacent to a sorter having a plurality of bins vertically arranged in an overlapping manner so as to accommodate therein through classification, paper sheets copied at a copying apparatus main body, said document accumulating apparatus comprising: an accumulating tray and an accumulating plate movably disposed at opposite sides of said bins for vertical movement; accumulating tray drive means and accumulating plate drive means for vertically displacing said accumulating tray and said accumulating plate respectively; and accumulating plate horizontal drive means for displacing said accumulating plate in a direction of said accumulating tray along the tray surface of each bin.
Claim 8
Dependent Claim
104 words
A document accumulating apparatus disposed adjacent to a sorter having a plurality of bins vertically arranged in an overlapping manner so as to accommodate therein through classification, paper sheets copied at a copying apparatus main body, said document accumulating apparatus comprising: an accumulating tray and an accumulating plate movably disposed at opposite sides of said bins for vertical movement; accumulating tray drive means and accumulating plate drive means for vertically displacing said accumulating tray and said accumulating plate respectively; and accumulating plate horizontal drive means for displacing said accumulating plate in a direction of said accumulating tray along the tray surface of each bin.
