ABSTRACT:
A paper transporting tractor for transporting paper provided with sprocket holes at an equally spaced interval along either side thereof includes a first endless belt having a plurality of sprockets at its outer peripheral surface and a serrated portion at its inner peripheral surface, a driving gear which is in mesh with the serrated portion of the belt thereby causing the belt to move either forward or backward, an end guide portion provided as spaced apart from the driving gear to provide the first endless belt as extended between the gear and the end guide portion and a second endless belt of thin film provided around the end guide portion as sandwiched between the first endless belt and the end guide portion at least partly thereby allowing to substantially decrease the friction between the first endless belt and the end guide portion.
