ABSTRACT:
In an automatic camera, as a film roll is loaded, the film is once wound up to its terminal end in response to a signal which indicates the closure of a rear lid of the camera. During such time, the number of film perforations is counted to allow the number of film frames which are available to take pictures to be known before any pictures are taken. A display is provided which is decremented as the frames are exposed and the film is wound back, thus indicating the number of film frames remaining.
