ABSTRACT:
A mechanism for use with a sheet transport apparatus for turning over a sheet transported along a travel path, such mechanism reliably functioning irrespective of sheet weight or size. With the mechanism, a sheet is selectively moved in one direction from a travel path or in an opposite direction into such travel path. The surface of the moving sheet is engaged so that energy derived by the sheet being transported in the direction from the travel path is stored. When the sheet is no longer being transported in such direction, the stored energy is utilized to move the sheet in the opposite direction to a point where it can be transported in such opposite direction back into the travel path with its trail edge becoming the lead edge and its surface orientation reversed.
