Abstract
A motion picture camera with an inner camera which has a camera mechanism that generates noise, a camera housing which has a lens carrier on which a photographic lens is disposed in the optical axis of the motion picture camera, and a plurality of noise-insulating connection elements disposed between the inner camera and camera housing. At least one of the noise-insulating connection elements is disposed parallel to the optical axis of the motion picture camera and has a higher rigidity relative to lower-frequency forces and a lower rigidity relative to higher-frequency forces.
Claims28
A motion picture camera comprising an inner camera, a camera mechanism that generates noise, a camera housing, a lens carrier attached to the camera housing, a photographic lens mounted on the lens carrier in an optical axis of the motion picture camera, and at least one noise-insulating connection element disposed between the inner camera and the camera housing, and said at least one noise-insulating connection element being disposed parallel to the optical axis of the motion picture camera and has frequency-dependent rigidity with a higher rigidity relative to lower-frequency forces and a lower rigidity relative to higher-frequency forces.
A noise-insulated motion picture camera comprising:
- an inner camera;
- a camera mechanism attached to the inner camera, the camera mechanism generating noise and vibration during operation;
- a camera housing enclosing the inner camera and camera mechanism;
- a lens carrier with a lens mounted on the camera housing;
- the lens and the inner camera defining an optical axis;
- a noise-insulating connection element disposed between the camera housing and the inner camera;
- and
- the noise-insulating connection element comprising a converter element capable of changing length to inhibit noise and vibration created by the camera mechanism from being transmitted to the camera housing, and a spring in parallel with the converter element.
A motion picture camera comprising:
- an inner camera, a camera mechanism to operate the inner camera, the inner camera and camera mechanism housed inside a camera housing having a primary housing and a carrier plate, a lens mounted on the carrier plate, a plurality of soft elastic connection elements linking the primary housing to the carrier plate, and at least one active noise-insulating connection element disposed to absorb vibration and noise in the direction of an optical axis of the camera.
The camera according to claim 28 further comprising a plurality of soft elastic connection elements linking the inner camera to the primary housing.
