Abstract: A recording apparatus comprising a magazine for storing a recording material, and a sensor for detecting a quantity of the recording material stored in the magazine. The magazine is movable between an inward position for supplying the recording material to a recording station and a position protruding from the apparatus body. A magazine moving device is provided which, in response to the sensor, moves the magazine from the inward position to the position protruding from the apparatus body.

Abstract: A film cassette sensing and retaining unit for film handling apparatus. The unit is responsive to completed insertion of a cassette into the film handling apparatus to mechanically latch the cassette in position and to electrically condition and actuate the film handling apparatus. Upon termination of operation of the film handling apparatus, the unit is effective to unlatch and eject the cassette and thereby deactuate the film handling apparatus. A disabling mechanism is provided to prevent premature unlatching and ejection of the cassette in a particular circumstance.

Abstract: An ejecting device for ejecting a film cartridge from a film cartridge chamber of a camera includes an elongated ejecting member which is pivotally mounted such that one end is positionable within the cartridge chamber through the floor thereof, and at the other end is operable to pivot the ejecting member upon the opening of the lid member of the cartridge chamber. The lid member is attached to one end of a double lever-type interlocking member, the other end of the interlocking member including a drive pin which is movable along an elongated slot in one side of the cartridge chamber. The drive pin is capable of operating the ejecting member, either through the intermediary of a drive member, or by contacting an integrally formed drive end of the ejecting member itself.

Abstract: Improved apparatus is provided in a viewer of the type having a film cassette receiving well defined in part by an opening in the viewer and an interior sidewall extending perpendicularly inward of the opening and from which extend outwardly a pair of drive heads. The improved apparatus is provided to guide the edge of the leading end wall of a cassette, as it enters the receiving well, past the pair of drive heads and ultimately into nesting relation adjacent the sidewall with the drive heads engaged to complementary recessed drive couplings in the side of the cassette upon complete insertion of the cassette into the well. The improved apparatus not only accommodates the ready insertion of the cassette within the receiving well, but also accommodates the ready removal of the cassette from the well by resiliently urging the bottom of the cassette to move in a direction outward of the cassette receiving well.

Abstract: A motion picture sound camera wherein a chamber in the camera housing can receive relatively small containers for regular motion picture film or relatively large containers for sound film. When the chamber receives a large container, the latter deforms a leaf spring which is thereby disengaged from a lever serving to move a component of the sound recording mechanism into engagement with an accessible portion of sound film in the inserted container. The lever can be moved in the opposite direction by a knob which is accessible from without the housing and is turnable by hand between a first and a second position. When moved from the first to the second position, the knob moves the lever and the component to a retracted position while simultaneously stressing a resilient ejector for containers in the chamber, unlocking the door for the chamber and resetting a film frame counter to starting position.

Abstract: A movie camera of the kind adapted for simultaneous motion picture and magnetic sound recording on a film in a cartridge, in which sound recording means including a magnetic recording head and a capstan are disposed in the camera body, and a swingable lever carrying sound recording means including a pinch roller is disposed in the camera body to be held in a retracted position when the cover of the camera is fully opened and kept in such position for the loading and unloading of the cartridge. In the movie camera, means are provided so that the pinch roller carried by the swingable lever can be urged to a position closely adjacent to the capstan and held temporarily in such position when the cartridge is loaded and the cover is closed, and then the pinch roller can be urged further toward the capstan to bring the sound recording track portion of the film into pressure contact with the capstan in response to the manipulation of the release for starting the motion picture taking operation.

Abstract: A movie camera capable of magnetic recording on a loaded film simultaneously with filming includes a pinch roller carried by a bracket which is swingable relatively to the camera body. The pinch roller is movable relatively to the bracket. The bracket is movable in response to the closing operation of a lateral cover of the camera to a position where the pinch roller is adjacent to a capstan and restrained immovably in the position. In response to the operation of a release element for initiating recording, the pinch roller is moved by a spring member into rolling engagement with the film to urge the same into contact with the capstan for recording on the film along a recording track.
