<p>A mechanism (10) supporting a device (50) for movement about a pair of substantially perpendicular pivot axes includes a pair of swing arms (22, 24) having bearing means (36,44) for supporting said device for pivotal movement about one of said pivot axes (41), which can pivot about a pair of inclined axes (30, 32), and which are mechanically interconnected for synchronous movement in opposite directions so as to cause the device to be adjustably positioned about the other of said pivot axes.</p> |
