摘要:
A device is disclosed for sensing, exchanging and storing data in a motion picture camera and cassette system comprising at least one motion picture camera 101, 102 and several film cassettes 201-204 containing an exposed and/or unexposed motion picture film. The film cassettes 201-204 contain a storage device which stores at least the length of the exposed and/or unexposed motion picture film. The motion picture cameras 101, 102 have a device for exchanging data with the storage device of the film cassettes 201-204 and sense the exposed length of motion picture film. Changes in the exposed film length are transmitted by the data exchange device of the film camera 101, 102 to the storage device of the film cassettes 201-204.
摘要:
A camera or a cartridge loading apparatus for a camera includes determination means (3), to move in response to a cartridge (1) being loaded, for determining whether the cartridge is unusable, supporting means for movably supporting the determination means, prevention means for preventing a movement of the determination means, the prevention means being provided independent from the supporting means.
摘要:
Camera apparatus operative with a film cartridge having a rotatable radial bar coded data disc thereon positioned at predetermined angular settings corresponding that indicate the condition of film in the cartridge, i.e. exposed, unexposed, partially exposed, etc.. The setting of the disc is determined during initial film spool rotation during the film loading process by counting with the optical sensor in the camera the number of bar code elements occurring between the initial set position of the disc and a reference position on the disc such as an edge of a quiet zone element normally included on the radial bar coded disc. The visual exposure indicator (VEI) positions on the cartridge are spaced about the perimeter of the cartridge such that there exist unambiguous element count ranges corresponding to each of the cartridge VEI positions. Element counting for this purpose can be performed in a cameras that operate to cause initial spool rotation during a film loading operation in either an unwind or rewind direction.

In a camera to be used with a self-opening cassette (1), an interlock for a cover piece of the camera and a light valve (57) of the cassette prevents the cover piece from being opened when the light valve cannot be closed because a filmstrip (F) is protruding out of the cassette
摘要:
A photographic camera (201) to be used with a film cassette (1) having film speed indicator means (171) movable between a storage position in which it cannot be detected to provide an indication of the speed of a filmstrip (F) inside the cassette and a use position in which it can be detected to provide the indication, is characterized in that a loading chamber (205) is configured to receive the film cassette with the film speed indicator means in the storage position, actuation means (209) is located in the loading chamber for moving the film speed indicator from the storage position to the use position responsive to insertion of the film cassette into the loading chamber, and sensing means (223) is located in the loading chamber for detecting the film speed indicator means when it is in the use position to determine the speed of the filmstrip inside the cassette.
摘要:
A film cassette (1) comprises a film spool supported inside a lighttight shell (3) for rotation to thrust a filmstrip coiled about the spool to the exterior of the shell, and a film exposure status indicator supported for rotation relative to the shell from an unexposed position for providing a visible indication that the filmstrip is unexposed to an exposed position for providing a visible indication that the filmstrip is exposed. The status indicator includes lock-out means arranged for engagement by a blocking member (211, 219) in a camera (201) to prevent insertion of the cassette into the camera, when the status indicator is in the exposed position, and a cut-out (123) located with respect to the lock-out means for receiving the blocking member to allow insertion of the film cassette into the camera, when the status indicator is in the unexposed position. The shell (3) includes cam means (125) aligned with the cut-out (123) for moving the blocking member (211, 219) out of the way of the cassette (1), when the status indicator is in the unexposed position, and covered by the lock-out means to be prevented from moving the blocking member out of the way of the cassette, when the status indicator is in the exposed position.
