Abstract

Abstract Reproduction apparatus for producing multiple image simplex copies and/or duplex copies in a single pass of a copy sheet through the apparatus. The reproduction apparatus includes a movable imaging member upon which at least first and second transferable images are carried. Transfer apparatus is provided for transferring the transferable images from the imaging member to a copy sheet. A copy sheet positioning assembly is operable in synchronism with the movable imaging member and the transfer apparatus in first and second modes. In the first mode, the positioning assembly positions one side of a copy sheet in transferable relationship with the movable imaging member at the transfer apparatus to successively transfer the first and second transferable images to one side of the copy sheet. In the second mode, the positioning assembly positions a copy sheet in transferable relationship with the movable imaging member at the transfer apparatus to successively transfer the first and second transferrable images to respective opposite sides of the copy sheet.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 127 words
Reproduction apparatus comprising: a movable imaging member upon which at least first and second transferable images are carried; transfer means for transferring said transferable images from said imaging member to a copy sheet; and positioning means operable in synchronism with said movable imaging member and said transfer means (1) in a first mode for positioning one side of a copy sheet in transferable relationship with said movable member at said transfer means to successively transfer said first and second transferable images to said one side of said copy sheet and (2) in a second mode for positioning a copy sheet in transferable relationship with said movable member at said transfer means to successively transfer said first and second images to respective opposite sides of said copy sheet.
Claim 2
Dependent Claim 127 words
Reproduction apparatus comprising: a movable imaging member upon which at least first and second transferable images are carried; transfer means for transferring said transferable images from said imaging member to a copy sheet; and positioning means operable in synchronism with said movable imaging member and said transfer means (1) in a first mode for positioning one side of a copy sheet in transferable relationship with said movable member at said transfer means to successively transfer said first and second transferable images to said one side of said copy sheet and (2) in a second mode for positioning a copy sheet in transferable relationship with said movable member at said transfer means to successively transfer said first and second images to respective opposite sides of said copy sheet.
Claim 3
Dependent Claim 160 words
The reproduction apparatus of claim 1 wherein said transfer means includes first and second transfer stations spaced along said imaging member and wherein said positioning means includes a copy sheet handling assembly which is (1) operable in said first mode to remove said copy sheet from said imaging member after transfer of said first image by said first transfer station to said one side of said sheet and to position said one side in transferable relationship with said imaging member at said first transfer station to receive said second transferable image on said one side and (2) operable in said second mode to remove said copy sheet from said imaging member after transfer of said first image by said first transfer station to said one side of said sheet and to position said other side of said sheet in transferable relationship with said imaging member at said second transfer station to receive said second transferable image on said other side.
Claim 4
Dependent Claim 41 words
The reproduction apparatus of claim 2 wherein said sheet handling assembly includes an endless member which is movable in opposite directions and wherein said first transfer station includes means for biasing said endless member to effect transfer of said transferable images.
Claim 5
Dependent Claim 14 words
The reproduction apparatus of claim 3 wherein said endless member includes a conductive roller.
Claim 6
Dependent Claim 217 words
Reproduction apparatus comprising: an image transfer member carrying at least first and second transferable toner images; first and second spaced electrostatic transfer means located along said image transfer member for transferring transferable images from said image transfer member; and a copy sheet handling assembly located adjacent to said image transfer member and associated with said first image transfer means, said sheet handling means being operable in a first mode to remove said copy sheet from said image transfer member after transfer of said first toner image by said first transfer means to one side of a copy sheet and to position said one side in transferable relationship with said image transfer member at said first transfer means so that said second toner image is transferred to said one side of said sheet by said first transfer means and (2) in a second mode to remove said copy sheet from said image transfer member after transfer of said first toner image to one side of said copy sheet by said first transfer means and to position said other side of said copy sheet in transferable relationship with said image transfer member at said second image transfer means so that said second toner image is transferred to said other side of said copy sheet by said second transfer means.
Claim 7
Dependent Claim 217 words
Reproduction apparatus comprising: an image transfer member carrying at least first and second transferable toner images; first and second spaced electrostatic transfer means located along said image transfer member for transferring transferable images from said image transfer member; and a copy sheet handling assembly located adjacent to said image transfer member and associated with said first image transfer means, said sheet handling means being operable in a first mode to remove said copy sheet from said image transfer member after transfer of said first toner image by said first transfer means to one side of a copy sheet and to position said one side in transferable relationship with said image transfer member at said first transfer means so that said second toner image is transferred to said one side of said sheet by said first transfer means and (2) in a second mode to remove said copy sheet from said image transfer member after transfer of said first toner image to one side of said copy sheet by said first transfer means and to position said other side of said copy sheet in transferable relationship with said image transfer member at said second image transfer means so that said second toner image is transferred to said other side of said copy sheet by said second transfer means.
Claim 8
Dependent Claim 81 words
The reproduction apparatus of claim 5 wherein said image transfer member carries a first set of successive transferable toner images and at least one other transferable toner image and wherein said first and second transfer means and said copy sheet handling means are operable in a third mode to successively transfer said first set of toner images to said one side of said copy sheet and then to transfer said second toner image to the other side of said copy sheet.
Claim 9
Dependent Claim 15 words
The apparatus of claim 6 wherein said first set of images are color separation images.
Claim 10
Dependent Claim 16 words
The apparatus of claim 5 including means for fusing said toner images to said copy sheet.
