Document Type and Number:
Japanese Patent JPS5055331
Kind Code:
A
Abstract:
A motion-picture-film-handling cassette, adapted to be mounted in a camera for exposure operations and in a projector for projection operations, which includes access apertures for a sound recording and playback system. The film strip contains a soundtrack and is advanced in incremental steps by a claw mechanism associated with the projector. During the projection operation, the film strip is additionally driven by a constant speed capstan, the latter having a flywheel attached thereto and forming part of the projector so as to extend into the cassette. Means are provided within the cassette for forming a loop of the film strip in a specifically located position for isolating the incremental movement of the film strip and soundtrack by the claw mechanism from the sound recording and playback system, the latter requiring a constant velocity soundtrack.
