ABSTRACT:
Apparatus for withdrawing exposed photographic roll film from a container wherein the film is adjacent a backing strip and the leader of the strip extends beyond the leader of the film. The container is mounted in a locating device so that a small opening in the rear wall of the container is located in the path of a pusher which, when pivoted forwardly expels the leader of the strip through the exposure opening of the container and into the nip of two rolls which advance the strip and thereby draw the leader of the film from the container. The leader of the film is intercepted and deflected by a deflector so that the film advances in an elongated channel and is engaged and moved forwardly by second advancing rolls. The inlet of the channel is defined by the deflector and a small idler roller which is mounted between the deflector and an edge forming part of the container and bounding a portion of the exposure opening. The roller holds the leader of the film against curling between the edge and the inlet of the channel, and the roller further insures that the emulsion-coated side of the film does not bear against and is not defaced by the edge when the film moved forwardly by the second rolls. The leader of the film is held against curling and/or folding in the channel.
