Abstract
Two endless paths are provided, one for an original sheet and one for a copy sheet. The paths have respective parallel portions which extend past a copy station at which an image from an original sheet in the one path is reproduced onto a copy sheet in the other path. At will, one or both sides of the original sheet can be copied and one or both sides of the copy sheet can receive copy. To expose both sides of the respective sheet to the copy station, the sheet passes once through its path to the outlet thereof and is then moved in reverse, from the outlet to a set of switching points which reintroduce it into the path while turning it side-for-side in preparation for another pass past the copying station.
Claims6
A copier, particularly for selectively copying one or both sides of a sheet-shaped original onto one or both sides of a copy sheet, comprising first means defining a first endless path for travel of said original and having a first inlet and a first outlet through which the original issues;
- second means defining a second endless path for travel of said copy sheet and having a second inlet and a second outlet through which the copy sheet issues;
- third means located at a copy station intermediate the respective inlets and outlets and operative for reproducing an image from either of said sides of said original onto either of said sides of said copy sheet;
- and fourth means for transporting said original and said copy sheet, respectively, in their associated paths, and for selectively turning the respective sheets side-for-side for renewed travel in their paths past said copy station, said fourth means including transporting elements mounted outwardly adjacent the respective outlets of said paths, and means for selectively reversing the transporting direction of said transporting elements when the respective sheets are to be reversed so as to return such sheets into the respective endless path.
A copier, particularly for selectively copying one or both sides of a sheet-shaped original onto one or both sides of a copy sheet, comprising first means defining a first endless path for travel of said original and having a first upstream branch provided with a first inlet, a first downstream branch provided with a first outlet through which the original issues, and a first shunting branch connecting said first upstream and downstream branches inwardly of said first inlet and outlet, respectively;
- second means defining a second endless path for travel of said copy sheet and having a second upstream branch provided with a second inlet, a second downstream branch provided with a second outlet through which said copy sheet issues, and a second shunting branch connecting said second upstream and downstream branches inwardly of said second inlet and outlet, respectively;
- third means located at a copy station intermediate the respective inlets and outlets and operative for reproducing an image from either of said sides of said original onto either of said sides of said copy sheet;
- and fourth means for returning the respective sheets with the respective endless path, thereby selectively shunting the respective sheets into the associated shunting branches and turning them side-for-side for renewed travel in their paths past said copy station.
