Claims

[Claims for Utility Model Registration] 1. A pair of left and right tractors each having a pin belt with a plurality of pins protruding from the outer periphery and a toothed pulley around which the pin belt is wound, and these tractors, a printing unit, and a paper feed roller and a driven roller which is arranged in close proximity to each other along the paper path, and integrally formed with the pin belt by extending laterally a flat extension part thereof, and which is brought into contact with the outer peripheral surface of these extension parts. A paper feed device for a printing machine, characterized in that it is rotatably provided. 2. A pair of left and right sprocket wheels each having a plurality of pins protruding from the outer periphery, a printing section, and a paper feed roller are arranged so as to approach each other in sequence along the paper path, and the sprocket wheels are provided with an extension portion having a flat outer periphery. 1. A paper feed device for a printing machine, characterized in that a driven roller is rotatably provided which is integrally formed to extend laterally and comes into contact with the outer circumferential surface of these extensions.
