ABSTRACT:
The present invention relates to a sound motion picture camera capable of the sound recording on the film at the same time with the film exposure by using a sound film cartridge containing a sound film and having an opening for enabling sound recording on the film by means of sound recording device, whereby the sound motion picture camera is provided with a preventive means for preventing the film cartridge from being improperly taken out of the cartridge loading chamber of the camera in the state in which the sound recording device is operatively engaged with the film in the opening of the film cartridge for recording the sound on the film.
The preventive means is in functional engagement with the camera release means or the running lock means so as to prevent the film cartridge from being taken out of the cartridge loading chamber only when the depression of the release means or the locking of the release means in the depressed position by the lock means is freed and the release means resumes the freed position so as to disengage the sound recording device from the film.
