Abstract

PURPOSE: To obtain an easy-to-operate swing and tilt mechanism, by using a combination lens having the prinicipal point of object and the principal point of image approximately in the same point as a photographic lens, and mounting such lens on the main body in such a way that the central axis of rotation of swing and tilt may pass through the principal point.
CONSTITUTION: A pair of supporting arms 2, 3 are mounted on a supporting frame 1 in a position adjustable manner, and a lens support board 4 and a film support board 5 are rotatably fitted to the arms 2, 3 around rotating shafts 6, 7. Bellows 8 are provided between the boards 4 and 5. A four-piece symmetrical lens having the principal point of object and principal point of image approximately in the same point is fitted to the lens support board 4 in such a way that the rotating shaft 6 may pass through the position of the principal point. Therefore, even when the lens support board 4 is rotated about the rotating shaft 6, deviation of image or off- focus will never occur. Thus, an easy-to-operate swing and tilt mechanism may be obtained.
