PURPOSE:To obtain an optical fiber scratching device by which a good cross section like a mirror surface is obtained by scratching uniformly an optical fiber from many directions. CONSTITUTION:A rotatable ratary ring 6 is arranged on a disc 5 having a slightly larger hole than a diameter of an optical fiber at the center and into this hole an optical fiber 2 to be cut is inserted. On the disc 5 a guide 14 having a fiber scratching mechanism part 9 is installed through a screw 13 and a spring 12 for adjusting blade pressure and on its tip part a cutter 8 comprising a diamond, etc., is placed. On the ring 6 a cam 15 like a triangle is installed with screws 16, 17. When the ring 6 is rotated, the triangular cam 15 forces down the fiber scratching mechanism part 9, and with the cutter 8 the optical fiber 2 is scratched. Blade pressure applied to the fiber 2 is adjusted with spring 10, 12 for blade pressure adjustment. |
