ABSTRACT:
In a cassette for a camera, two filter wheels are provided. Each filter wheel is held between two guide wheels and a drive wheel. The drive wheel is driven by a miniature electric motor. For each filter wheel, one associated guide wheel is connected to a lever. By lifting the lever, the filter wheels are released and can be taken out of the cassette. A code field is provided along the circumference of each filter wheel. Each code field is read by reading means. In this way, each filter element on each filter wheel can be moved into the optical path of the camera. The electric connections terminate in a plug which during insertion of the cassette mates with a socket in a rear wall of the camera. The cassette may also be provided with a test-slide projector for focusing the pickup tubes in a camera.
