<p>A three-dimensional rotation mechanism comprising a configuration including: a first frame body (3); a first frame body-driving mechanism (7) for rotating the first frame body (3) about a first rotation axis; a second frame body (9) provided within the frame of the first frame body; a first following mechanism (13; 19, 20, 21, 23) for rotating the second frame body (9) about a second rotation axis, which is perpendicular to the first rotation axis, in such a manner that the second frame body (9) follows the rotation of the first frame body (3); a body (15) to be rotated, provided within the frame of the second frame body (9); and a second following mechanism (17; 29, 31, 33, 35) for rotating the body (15) to be rotated, the second following mechanism being adapted to rotate the body (15) about a third rotation axis in such a manner that the body (15) follows the rotation of the second frame body (9). The configuration causes a centrifugal force due to the rotation of the three axes to act on the body (15) to be rotated, and as a result, the so-called co-rotation in which the body (15) and an object contained therein rotate integrally is prevented from occurring.</p> |
