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. The operation is carried out stepwise so that, at the first position, the movable device operates while the openable cover is locked; at the second position, the movable device does not operate while the openable cover is locked; and at the third position, the movable device does not operate while the openable cover is freed. At least one of the three position being non-linear with respect to the other two.
