PURPOSE:To divide and intergrate a light transmission loop with a minimum number of change-over contact parts, by changing mutually opposite light transmission lines of counter plane parts, by relatively rotating a couple of fitting members on the shaft by 180 deg.. CONSTITUTION:Fitting members 81 and 82 for optical fibers are installed in case 80; member 82 is fixed to the case, and member 81 is fixed on shaft 83 connected direct to motor 84. Members 81 and 82 have contiguous opposing plane parts and are provided with butt connection surfaces between optical fibers 90-93, and 94-97. In this case, optical fibers 105 and 106, and 107 and 108 are fitted on the diagonal lines of the counter plane parts of fitting members 101 and 102, and turning fitting member 101 by 180 deg. changes the mutually opposite optical fibers. |
