置。[Claims for Utility Model Registration] (1) A sprocket with engaging teeth that engages with the film perforation is rotated following a spool driven by a motor, thereby feeding the leader portion of the film into the spool. In the film feeding device, the sprocket includes a rotary plate that is rotated following the spool, an elastic arm that is integrally formed with the rotary plate and has an engaging tooth at one end, and an elastic arm that connects the engaging tooth to the film perf. It is composed of an integrally molded product including a holding part for holding the oration in the engaging position, and when the engaging tooth comes into contact with the film surface, the elastic arm bends due to the repulsive force from the film surface. A film feeding device characterized in that the engaging teeth are retracted from the engaging position. (2) The film feeding device according to claim 1, wherein the engaging teeth are retracted in a direction along the film feeding direction. (3) The film feeding device according to claim 1, wherein the sprocket is a one-tooth sprocket having a single engagement tooth.
