摘要： The camera of this invention has a film cassette compartment, a film spool (13), a film exposing area, and an interlock that prevents moving exposed film from the film cassette. With the camera, a film cassette (2) is loaded into the film cassette compartment. The film is then locaded by moving the film from the film cassette (2) compartment across the film exposing area and winding all but the first frame of film to be exposed around the film spool. After a picture taken, the exposed film is wound back into the film cassette and the next from of film to be exposed is moved into the film exposing area. The interlock prevents moving the exposed film out of the film exposing area. In an embodiment the interlock includes a lever that is engageable with the serrations of a film rewind wheel (22) to prevent movement of the film rewind wheel (22).
