PURPOSE:To decrease the amt. of irregularity in cutting in the case of simultaneous cutting of multiple optical fibers by driving a cutting blade to give initial flaws to the optical fibers by an electric motor, by which the specular surfaces perpendicular to the optical axis of the optical fibers are obtd. with good accuracy. CONSTITUTION:The optical fibers 19 fixed to a fixing jig 17 are spanned on a lower clamping member 20. The cutting blade 22 is driven by the rotation of the electric motor 36 and the initial flaws are given to the surfaces of the optical fibers 19. A 2nd upper case 13 is deflected to further push a cutting head 27 downward to bend the optical fibers downward. The initial flaws given to the optical fibers are, therefore, expanded and the optical fibers are fractured. The fluctuation in the moving speed of the motor at the time of giving of the initial flaws is suppressed in this way and the specular surfaces perpendicular to the optical axis of the cut surfaces are accurately obtd. The amt. of the irregularity in cutting in the case of simultaneous cutting of the multiple optical fibers is decreased. |
