ABSTRACT:
The camera has a picture image recording mechanism to record a picture image on a picture image recording part of the film, a sound recording mechanism to record sound information at the film having sound recording part, a constant speed film feeding mechanism having a capstan and a pinch roller to run the film at a constant speed at a sound recording head part of the sound recording mechanism, and a release member which controls initiation of a camera and is mechanically linked selectively with the sound recording mechanism and the constant speed film feeding mechanism, and which can simultaneously record a picture image and sound at the film within the cartridge when the film cartridge for simultaneous sound recording is loaded. The system includes a change over mechanism for releasing the above mentioned mechanical link between said release member and the sound recording mechanism and the constant speed film feeding mechanism when the above mentioned silent film cartridge is loaded for placing the sound recording mechanism and the constant speed film feeding mechanism in an inoperative state irrespective of function of the release member, and mechanically linking said release member with the above mentioned sound recording mechanism and a constant speed film feeding mechanism when the above mentioned simultaneous sound recording film cartridge is loaded, so that the sound recording mechanism and constant speed film feeding mechanism are placed either in an operative state or an inoperative state corresponding to the action of the above mentioned release member.
