ABSTRACT:
The present invention relates to a motion picture camera which includes an openable cover for loading a film magazine containing a film capable of recording sound information. A sound recording device for recording the sound information on the film and a movable device for moving either the sound recording device or the film to a position at which the sound can be recorded is also included. An operation device for operating the opening and the closing of the openable cover can be displaced to three positions, i.e. the first, the second and the third position.
