ABSTRACT:
In a mechanism for controlling the movements of a dirigible scanning head, movement about one of three orthogonal axes is imparted to the head by means of a pair of flexible straps which are fastened to the head at opposite sides of said one axis and extend along a part-circular track at the back of the head that is centered on said one axis. The straps are wrapped around respective rollers mounted on a carrier that is itself displaceable in a direction generally along the track by a coupling to an endless flexible band driven by an electric motor-drive. The straps and the drive means for them are carried by the head for rotation with the head relatively to a support member about a second of the three axes.
The straps support conductors for carrying electrical supplies to those units of the scanning head that so require.
