摘要： A film cassette comprises a spool supported inside a shell for rotation to thrust a filmstrip coiled about the spool to the exterior of the shell whether the filmstrip is unexposed or is partly exposed, and a film exposure status indicator secured to the spool for rotation from an unexposed position for providing a visible indication that the filmstrip is unexposed to respective partly exposed and fully exposed positions for providing visible indications that the filmstrip is only partly exposed or is substantially exposed. A spool lock is supported for movement to arrest the spool with the film exposure status indicator in the unexposed, partly exposed or fully exposed position, and to release the spool. According to the invention, the spool lock includes a film speed indicator for providing a detectable indication of the speed of the filmstrip which is not detectable when the spool lock is arresting the spool and is detectable when the spool lock has released the spool.

摘要： A film cassette comprises a spool supported within a cassette shell for rotation about an axis to thrust a filmstrip coiled about the spool to the exterior of the shell whether the filmstrip is unexposed or is only partly exposed, and a film exposure status indicator supported for rotation within the shell about the axis from an unexposed position to respective partly exposed and fully exposed positions for providing visible indications that the filmstrip is only partly exposed or is substantially exposed. According to the invention, the spool and the status indicator are fixed coaxially to each other. The spool has three spaced detents arranged at separate locations for respective engagement to lock the indicator in its unexposed, partly exposed and fully exposed positions. The shell has an end cap including a locking pawl normally urged to individually engage any one of the detents, but which can be moved to disengage any one of the detents by a suitable device in a camera.

摘要： A film cassette comprises a film spool supported inside a lighttight cassette shell for rotation to thrust a filmstrip coiled about the spool to the exterior of the shell whether the filmstrip is unexposed or is only partly exposed, and a film exposure status indicator supported for rotation relative to the shell from an unexposed position to respective partly exposed and fully exposed positions for providing visible indications that the filmstrip is only partly exposed or is substantially exposed. The status indicator includes integral lock-out means capable of being detected for the purpose of preventing insertion of the film cassette into various cameras intended to be used with the film cassette. A cap for covering the lock-out means to prevent the lock-out means from being detected includes respective window-like means for revealing the lock-out means when the status indicator is in its partly exposed and fully exposed positions. Thus, the film cassette can be used with a relatively simple camera intended to receive the film cassette only with fresh unexposed film and a more complex camera intended to receive the film cassette with unexposed or partly exposed film.

摘要： A film cassette comprises a film spool supported inside a lighttight cassette shell for rotation to thrust a filmstrip coiled about the spool automatically to the exterior of the shell, and a film exposure status indicator supported for movement with respect 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. According to the invention, the shell and the status indicator include mutually engagable pin and hole for locking the indicator in its unexposed position to prevent the indicator from being manually moved to its exposed position but which can be disengaged by a suitable device in a camera, for example, to unlock the indicator to permit the indicator to be mechanically moved to the exposed position.

摘要： A film cassette comprising a cassette shell having an end face with an end opening, and a rotatable spool core supported inside the shell with one end protruding through the end opening to outside the shell, is characterized in that a covering label is affixed to the end face of the shell and to the one end of the spool core to prevent rotation of the spool core. The covering label is frangible to allow it to be broken to permit rotation of the spool core and to provide a visible indication the cassette was used. The end face of the shell has a relieved area which immediately surrounds the end opening in the end face along a location beneath the covering label. When the cassette is loaded into a photographic camera, a fracturing piece is received into the relieved area which breaks the covering label.

摘要： A photographic camera is to be used with a film cassette having a film exposure status indicator normally secured in an unexposed position for providing a visible indication that a filmstrip within the cassette is unexposed and releasable from the unexposed position to permit its movement to an exposed position for providing a visible indication that the filmstrip is exposed. According to the invention, the camera includes a loading chamber configured to receive the film cassette with the status indicator secured in the unexposed position, and release means located in the loading chamber for releasing the status indicator to permit its movement to the exposed position.

摘要： A film cassette comprises a film spool rotatable inside a lightight cassette shell in an unwinding direction to thrust a filmstrip coiled about the spool automatically to the exterior of the shell, and a film exposure status indicator movable 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. According to the invention, the spool, the shell, and the status indicator include respective cooperating means for preventing rotation of the spool in the unwinding direction when the status indicator is located in its unexposed position, but which can be rendered ineffective (by a camera device, for example) to allow rotation of the spool in the same direction.
