CUTTING DEVICE OF OPTICAL FIBER AND CUTTING METHOD OF OPTICAL FIBER, AND BLADE MEMBER FOR CUTTING OPTICAL FIBER

摘要

A cutting device of optical fiber, a cutting method of optical fiber, and a blade member for cutting an optical fiber which can ensure good workability through a simple arrangement while reducing the cost. The cutting device (10) of optical fiber comprises clamps (20U, 20L) for securing an optical fiber (11) by clamping both the sides of the cutting portion of the optical fiber (11) in the axial direction, a blade member (30) for imparting an initial flaw (11a) to the cutting portion of the optical fiber (11) gripped by the clamps (20U, 20L) by pressing the point of blade (31) against the cutting portion of the optical fiber (11), a blade feed mechanism (40) for updating the position of the blade member (30) such that the unused portion of the point of blade (31) touches the optical fiber (11) at the time of cutting, a pillar member (50) for breaking the optical fiber (11) by pressing it from the side opposite to the initial flaw (11a) imparted by the blade member (30) thereby applying a tensile bending force, and a blade pressure setting spring (32) for energizing the blade member (30) toward the optical fiber (11) with a predetermined resilient energizing force.
