Optical fiber cutting device

An optical fiber cutting device in which a scratch is formed in an outer peripheral surface of an optical fiber and the optical fiber is cut, comprising:

• an anvil;
• two clamps which are spaced from each other in an optical axis direction, the clamps clamping the optical fiber such that the scratch is disposed between the clamps, the anvil applying at least one of a tension force and a bending stress to brake the optical fiber at the scratch such that cut surfaces of the optical fiber are mirror surfaces of each other, and such that a waste fiber is provided as a front portion of the cut optical fiber, one of the two clamps being two pinch rollers which pinch the waste fiber, the anvil being disposed between the two clamps;
• a biasing device;
• the anvil being movable downwardly by press-down operation and upwardly by the biasing device upon termination of the press-down operation;
• a drive mechanism which connects the anvil and the pinch rollers such that downward movement of the anvil causes rotation of the pinch rollers;
• and
• a collecting container, which collects the waste fiber, disposed downstream of the pinch rollers, wherein by the anvil traveling downwardly, the bending stress or resulting tension force is applied to an adjacent portion of the scratch so that the optical fiber is broken at the scratched portion, the pinch rollers are rotated by said drive mechanism only in a direction along which the waste fiber is sent toward said collecting container, and by the pinch rollers rotation, the waste fiber pinched by the pinch rollers is conveyed and collected into the collecting container.
