发明名称 Film threading apparatus
摘要 In a camera, a film threading apparatus operates to feed a film leader extending out of a film cassette from a supply chamber to a take-up chamber. The film cassette is loaded in the supply chamber with the film leader positioned in a film passageway between the supply and take-up chambers. A film threading member is located adjacent the leader, with a non-film engagable section of the threading member confronting, though spaced from the leader. When a camera door is closed, a drive mechanism causes the threading member to be revolved, moving a film engagable section of the threading member to engage and advance the film leader to a film capturing mechanism in the take-up chamber. The threading member is stopped with its non-engagable section again confronting the film leader to prevent the threading member from interfering with subsequent film advance.
