An internal magnet provided in the sealed container is movable with respect to the sealed container, and an internal member is moved by movement of the internal magnet. The external magnet and the internal magnet are arranged in such a manner that the internal magnet is moved by the action of a repulsive force between the external magnet and the internal magnet based on movement of the external magnet.

Abstract: A camera control unit for processing a signal output from an imaging device incorporated in an endoscope is provided with an analog video signal output terminal through which a video signal is output to a monitor, and a digital video signal output terminal to which a still image-specific or motion picture-specific expansion unit is coupled in a freely detachable manner. By handling a release switch, a still image or motion picture can be recorded digitally. Even when the recorded image data is edited or subjected to any other processing, deterioration of image quality can be prevented. An imaging system having these advantages can be realized on a small scale.
