发明名称 Film cassette and method of assembling the same
摘要 A film cassette is disclosed wherein a filmstrip in roll form is stored within the cassette shell and has a leader that projects from an exterior end of a film passage slit in the cassette shell to permit the filmstrip to be drawn out of the shell. According to the invention, the leader has a forward edge portion that is folded back onto a successive portion of the leader to prevent the leader from being moved completely through the exterior end of the film passage slit into the cassette shell. Preferably, the forward edge portion of the leader is secured to the successive portion of the leader to form a looped portion of the leader between the forward edge and successive portions which may be engaged in a camera, for example, to draw the filmstrip out of the cassette shell.
