A panoramic motion picture camera (20) for continuously nonintermittently exposing a filmstrip (35) in which a camera body assembly includes a stationary housing portion (22) and a rotatable housing portion (23), the rotatable housing portion including an upper housing section and a lower housing section rotatable about an axis of rotation (24). Camera components including a lens means (30), a main film sprocket (37), a film supply sprocket (36), and film idler spools providing a film path are enclosed within the upper housing section while a film supply reel (31) and film take-up reel (32) coaxially arranged and in spaced planar zones are contained within the lower housing section of the rotatable portion. Bidirectional film spools translate the filmstrip from the supply reel (31) to the film path provided in the upper housing section and thence to the film take-up reel (32) at the lower part of the lower housing section. In the stationary housing portion motor drive means are provided for the main film sprocket, the supply and take-up reels, and the rotatable housing portion (23). Brake means is provided in the stationary housing portion for stopping rotation of the main film sprocket to cause relative movement of the filmstrip past the film gate of the lens means. A method of operating such a panoramic camera in which film is conserved when the camera is stopped by closing the film gate by actuation of a capping shutter, reversing the filmstrip to displace a portion of the exposed film backwardly of the film gate, and utilizing the displaced exposed film portion as a leader during the next start-up of the camera while the shutter remains closed, and opening the shutter after the displaced film portion passes the film gate. A novel film guide spool for directing a filmstrip in two directions for guiding film between two spaced planar zones. |
