Abstract
A reproducing machine in which successive images are formed on opposed sides of a copy sheet to produce a duplex copy. The copy sheet is inverted after an image is transferred to one side thereof at a first transfer zone. A second transfer zone receives the inverted sheet and transfers an image to the other side of the copy sheet. Thereafter, both images are permanently affixed to the copy sheet.
Claims8
A reproducing machine for forming successive images on opposed sides of a copy sheet to produce a duplex copy comprising:
- a member arranged to have a first image and a second image recorded thereon, said member driven to move through a first plane through a first transfer zone and then change direction to move through a second plane through a second transfer zone;
- a tray pivotably mounted near said member and having a surface for receiving said copy sheet;
- drive means for moving said copy sheet away from said tray along said second plane;
- said drive means having a number of spaced belts moving in said second plane to engage said copy sheet;
- and
- means for pivoting said tray to a first position where said surface is co-incident with said first plane for receipt of a copy sheet as said member moves said sheet past the first transfer zone and away from said member as said member changes directions, said means for pivoting also operative to pivot said tray to a second position where said copy sheet engages said spaced belts thereby advancing said sheet through said second plane to said member and said second transfer zone.
