ABSTRACT:
A motion picture camera for use with regular motion picture film or with motion picture film having a sound track and being stored in containers larger than those for the storage of regular film so that, when the chamber in the body of the camera received a small container, such small container leaves unoccupied a portion of the chamber which is occupied when the chamber receives a large container. A properly inserted large container deforms a leaf spring which extends into the aforementioned portion of the chamber whereby the thus deformed leaf spring enables a first lever to permit the pivoting of a second lever under the action of a torsion spring. The second lever moves a roller into engagement with film in a properly inserted large container opposite a rotary element which is adjacent to a sound head of the sound recording mechanism in the camera body. The roller can be disengaged from film in a large container in response to rotation of a knob constituting a component part of a locking device for a cover which must be opened in order to afford access to the chamber in the camera body.
