Claims

[Scope of utility model registration request]

A paper outlet is formed on a part of the outer periphery of a magazine case that stores rolls of photographic paper, and a pair of feed rollers is provided on the photographic paper transport path leading to the paper outlet, and the roller shaft of one feed roller is connected to the other feed roller. The roller shaft of the one-side feed roller is supported movably and the spring elasticity that presses the one-side feed roller against the other feed roller is applied to the roller shaft of the one-side feed roller, and a knob provided on one end of the roller shaft and the outer surface of the magazine case. A cam is fixed to the other end of the roller shaft, and a contact is supported around the cam so as to be movable in the axial direction of the roller shaft. A spring is provided to return the cam to the position, and a stopper surface is formed on the outer periphery of the cam that extends radially at one end of the base circle, and continues to the other end of the base circle and has a step in the radial direction with respect to the base circle. A crimp release cam surface on the feed side and a crimp release cam surface on the winding side are provided in parallel in the axial direction, and the circumferential length of the crimp release cam surface on the feed side is shorter than the circumferential length of the crimp release cam surface on the winding side. Thus, the paper magazine is provided with a transverse feed cam surface on one side of the terminal end of the feed side crimp release cam surface for moving the contactor toward the starting end of the take-up side crimp release cam surface.
