A roll film camera of the type in which the exposed film must be rewound onto a supply reel within a magazine before the back cover of the camera is opened to remove the magazine from its chamber within the camera body. As a rewinding crank is operated by hand, when the film nears the terminal end as detected by a probe extending into the transport path of the film, motion of the handcrank begins to be transmitted to an operating member for controlling a locking and unlocking operation of the back cover. It is thereby insured that the film is protected from fogging when the magazine is removed. Even with a camera having a motor drive unit, it is possible to leave the film unrewound protruding from the magazine by a limited terminal length which provides for easy handling of the film in the later processing operation.
