ABSTRACT:
An endless belt used in a paper feeding apparatus for feeding paper to a printer in a computer or the like, the paper having feed holes formed at equal intervals in both side portions thereof. A large number of feed pins to be inserted into the above feed holes are formed on the outer peripheral surface of the endless belt. The feed pins are arranged so that there is repeated a pattern of interaxial spacings of P+a/2, P+a/2, P-a/2 and P-a/2, in which P is the distance between the centers of feed holes formed in the paper and a is a mean value of differences between feed pin outside diameters of the portions in abutment with edge portions of the feed holes and the feed hole diameter. Alternatively, the feed pins may be arranged at interaxial spacing between adjacent feed pins of P+a and P-a alternately.
