Abstract
In a camera having a film transport mechanism for advancing and rewinding film and a counter for counting the number of frames of film advanced, a first control device operatively coupled to the counter controls the transport mechanism so as to prevent further film advancement upon the counter reaching a predetermined count. Upon the transport mechanism being operated to rewind the film, a second control device automatically disables the first control device so as to enable further film advancement by the transport mechanism.
