Abstract:
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 said holder tables and having guide grooves into which tip end portions, from which coatings are removed, of said two optical fibers held by said holder tables are fitted, and fiber clamps capable of rotating from their waiting positions to positions above said guide grooves and adapted to press said tip end portions of said optical fibers, which are fitted in the guide grooves, into said guide grooves, said screening mechanism comprising:a sensor capable of detecting the fact that the pressing of said tip end portions of said optical fibers effected by said fiber clamps is released; and wherein when the releasing is detected by said sensor, one or both of said two holder tables are automatically shifted in directions opposite to optical fiber abutting directions to pull said optical fibers, thereby effect screening.
