PURPOSE:To accomplish construction of a compact light-coupling device, by connecting the top end of optical cable wound upon the revolving units to moving units, with the rear end being led into revolving units, winding optical fibers branched from the optical cable upon the dummy bobbins which are jointly revolving coaxially with said revolving units, and connecting said rear end to the stationary terminal unit through bobbins connected to respectively different shafts. CONSTITUTION:For example, the optical cable 2 having five cores connected to the sea-bottom explorer 3, is wound upon the revolving unit 1, and said cable 2 enters into said revolving unit 1 through the passage hole 1a, and the two pieces branched into the optical fibers 2a respectively arrive at the revolving joints 5a, 5b, while the other 3 pieces are respectively wound upon the dummy bobbins 15x-15z, and then arrive at the revolving joints 5x-5z, through the 3 bobbins 18x-19z, having differet shafts each, and then connected to the stationary terminal units 8a, 8b, 8x-8z, respectively. The revolving unit 1 is revolved by the motor 12 through the pulleys 11, 13 and the belt 14, and the bobbins 18x-18z are revolved by the belts 21x-21z, respectively. Thus, said moving units are connected to said stationary terminal units without any obstacle, enabling compactification of the device. |
