PURPOSE:To minimize a connection loss of an optical fiber line fixed to each block, and to connect and reconnect with high accuracy by aligning a movable block for fixing the end part of the other optical fiber line in plural positions for a fixing block for fixing the end part of one optical fiber line. CONSTITUTION:A pin detaching frame 11 is slid to the left while resisting against a spring force of a pressure spring 91, the tip part of an aligning pin 7 is drawn out of a movable block 3 and a switching slider 8 is slid to the right. Accordingly, a shift form spring 81 moves, while coming into contact with the lower face of the movable block 3, and when the movable block 3 is raised by an inclined part, and also, moved to the right, it is supported by a first position supporting part 81A. Thereafter, when holding of the pin detaching frame 11 is stopped, the aligning pin 7 slides and moves in a pin hole 5 by the spring force of the pressure spring 91, and its tip tapered part 71 goes into a pin hole 6 of the movable block 3. In such a way, a precise alignment of both the blocks 3, 4 is secured, and an optical connection of an optical fiber line 2 and an optical fiber line 1B is completed. |
