<p>The present invention provides a screening mechanism for an optical fiber fusion-splicer including two holder tables for holding two optical fibers to be fusion-spliced in an opposed relationship, a connection table disposed between the holder tables and having guide grooves into which tip end portions, from which coatings are removed, of the two optical fibers held by the holder tables are fitted, and fiber clamps capable of rotating from their waiting positions to positions above the guide grooves and adapted to press the tip end portions of the optical fibers into the guide grooves, the screening mechanism comprising a sensor capable of detecting the fact that the pressing of the tip end portions of the optical fibers effected by the fiber clamps is released, and wherein, when the releasing is detected by the sensor, one or both of the holder tables are automatically shifted in directions opposite to optical fiber abutting directions to pull the optical fibers, thereby effect screening <IMAGE></p> |
