Abstract: A sound module for motion picture cameras of the type adapted to receive a multi-purpose cassette in which separate photographic film and audio tape strips are commonly wound on cassette-contained supply and takeup spools but directed through separate paths between the spools, such paths including distinct photographic and audio or sound stations. The module carries a complete complement of sound recording components including a transducing head, a capstan drive and motor for advancing a run or loop of the sound tape past the transducing head and an organization of fixed and movable sound tape guiding members by which the positional relationship of the tape and the transducing head is accurately controlled. All components of the module are ultimately supported by a single supporting plate secured to the internal camera chassis structure by vibration damping means. The module is also associated with camera control functions in a way such that cassette insertion and removal from the camera is unimpeded by sound module carried components.
