ABSTRACT:
A small-sized tripod head for tilting or panning a television camera or the like by remote control. The connecting cable of the tripod head does not obstruct a smooth motion of the tripod head. Annular terminals are disposed on the outer periphery of a driving shaft extending over 360 degrees, and brush contacts which come into contact with the annular terminals are provided on the main body. The annular terminals and the contacts constitute a power supply line, which allows the driving shaft to rotate more than 360 degrees. A light guide is disposed at the center of the driving shaft, and a photoelectric transducer is provided on the main body in such a manner as to be isolated from the light guide. A control signal, a video signal, etc. are transmitted by the light guide and the photoelectric transducer. This light signal transmission line can transmit various light signals by using a plurality of beams having different wavelengths obtained by a beam splitter.
