ABSTRACT:
A photographic camera which is fully automated in the film winding and rewinding operations is provided. In one form of the present camera, the film winding operation may be automatically moved into the film rewinding operation by detecting the end of the film, for example, by detecting the fact that the tension of the film has exceeded a predetermined level. In another form, a planet gear mechanism is provided in the power transmission train so as to minimize the consumption of energy. In a further form, the camera is provided with an automatic film loading or setting mechanism and an alarm unit for generating an alarm signal when the failure of automatic film setting has been detected. In a still further form, the camera may be operated without film loaded in the camera.
