Abstract: A motion picture camera is adapted to receive a film magazine containing a roll of sound recordable photographic film. A housing forms a chamber to receive the magazine. A cover opens and closes the chamber. A recording system records sound signals on the film. A setting arrangement engages the recorder system and the film with each other so as to record signals. The setting arrangement is movable into a first position where the film engages the recorder and a second position where the film is disengaged from the recorder so as to be incapable of recording sound signals. A transport device is coupled to the setting arrangement in the first position when the recorder is in the first position. An interconnecting system responds to closure of the cover for moving the setting arrangement from the second position to the first position so that the camera can be set for sound signal recording in response to the closing of the cover.

Abstract: A system is disclosed for retrieving a film having video information recorded thereupon in synchronism with a magnetic tape having audio information recorded thereupon and for synchronizing the sound with the picture after retrieval. Address signals are recorded upon both the film and the tape. The system comprises detectors for address signals recorded upon the film and the tape, a computer including a keyboard for retrieving a desired address, comparators for comparing the outputs of the detectors with the output of the computer, and means for transporting the film and tape in response to the outputs of the comparators. Control signals are recorded upon both the tape and film for synchronizing the sound with the picture. When the control signal recorded upon the film is detected, the still picture is projected and when the control signal recorded on the tape is detected the motion picture is projected.

Abstract: Automatic and rapid exposure control is incorporated in a camera having facilities for directing, along a common path, a pair of independent noncoincident light beams from an external object and from a separately illuminable item, such as a databearing transparency within the camera. A photoelectric circuit responsive to the total quantity of the directed light generates a proportional control voltage for operating an adjustable diaphragm to maintain a predetermined incident level of the directed light on the camera film and/or controlling the item illuminator or an auxiliary illuminator for the external object. Threshold controlled, motor-instrumented apparatus may be additionally provided to advance the film, to selectively operate a camera shutter, and to illuminate the item in response to trigger signals generated, e.g., upon the detection of the presence of the external object.

Abstract: An automatic shutter control system for a camera includes a continuous rotatable motor coupled to a pair of separately engageable electromagnetic clutches. The clutches are respectively operable, when engaged, for releasing the shutter to commence exposure and for winding up the shutter after exposure has terminated. When camera operation is initiated, the first clutch is engaged to release the shutter and to trigger the start of a manually selectable exposure duration. At the conclusion of the selected duration, the first clutch is disengaged and the second clutch is engaged to begin the wind-up of the shutter. An inertial sensor on the motor terminates the wind-up operation and disengages the second clutch when the increased torque on the motor from wind-up reaches a predetermined value.
