摘要： A lens-fitted film unit is preloaded with photographic film, and has an eight-toothed driven sprocket wheel in mesh with perforations on the film. When the photographic film is fed by one frame, the sprocket is caused to make one rotation. A shutter mechanism is cocked responsive to rotation of the sprocket. During assembly of the film unit, the shutter mechanism is cocked. The photographic film is loaded while the shutter mechanism remains cocked. In a preferred embodiment, the sprocket is set in a predetermined rotated position which is two teeth short of the position at the end of one winding up of the film. This brings the shutter mechanism into an incompletely cocked state. The photographic film is loaded while the shutter mechanism remains in the incompletely cocked state. In the film unit, a film passageway is provided behind the main body, for passage of the film. A shiftable engaging portion projects into the film passageway in retractable fashion. A notch is formed in an edge of the film, is engaged with the shiftable portion, and during assembly properly positions the film within the film passageway relative to the lengthwise direction of the film.

摘要： A camera has a first charge mechanism for charging a mirror, a second charge mechanism for charging an aperture diaphragm, a third charge mechanism for charging a shutter, an exposure preparation mechanism for performing an exposure preparation operation in response to a releasing operation, a selector for distinguishing between single-shot photographing and continuous photographing, a first detector for detecting completion of charging of the mirror, a second detector for detecting completion of charging of the aperture diaphragm, a third detector for detecting completion of charging of the shutter, and a controller for executing a flow of control such that, when the selector detects continuous photographing being performed and in addition the first and second detectors detect completion of charging of the mirror and the aperture diaphragm, the exposure preparation operation is started irrespective of the result of detection by the third detector.

摘要： A camera comprises a film feed device (9) for feeding a light-sensitive film arranged in the camera, a photographic shutter (10) for the image-forming exposure of the light-sensitive film and arranged in the optical path for the image recording, and a shutter release device (300) which before the shutter release adopts a readiness position and after the shutter release adopts a disengaged position and which has a spring reservoir (314, 315) that is tensioned by adjusting the shutter release device from the readiness position to the disengaged position in order to actuate the shutter (10), wherein the spring reservoir (314, 315) of the shutter release device (300) is not tensioned in the readiness position and in the disengaged position thereof and a return of the shutter release device (300) from the disengaged position to the readiness position is controlled by a control device (104, 106) that moves when feeding the film.

摘要： A motor-driven single-lens reflex camera which controls and executes, through forward and reverse rotation of a single motor, a mirror up/down operation and a shutter charge operation by a mirror/shutter driving system, and also a film winding/rewinding operation by a film feeding system. The mirror up and the shutter charge release operations are executed through forward rotation of the motor, and the mirror down, the shutter charge and the film winding/rewinding operations are executed through reverse rotation of the motor. Thus the speedy film feeding after exposure can be made without stopping or reversing drive of the motor.
