(Prior Art) In general, in various printers, typewriters, etc. used as output devices for electronic computers, etc., in order to feed paper used therein, pins of an endless belt with pins are used to feed paper along both sides of the paper. A bin tractor is used that feeds the paper by engaging the hole and rotating a belt with pins.

(Problems to be Solved by the Invention) In the above-mentioned bin tractor, the guide groove has guide surfaces close to both side edges of the belt with pins, and the paper feeding surface of the belt (the surface of the belt base band) is in contact with the frame surface. Since the belt with pins runs so as to be in contact with the road surface, slip resistance between the paper and the frame surface during paper feeding causes a paper feeding load, resulting in poor paper feeding performance. This tendency is particularly noticeable in the case of paper with rough paper quality.
