には動作時間が長くなるという欠点を有している。In the prior art, an optical fiber peeling device was used for each core wire (for example, the conventional example of FIG. 14 shown in Japanese Patent Application No. 60-79535 “Optical Fiber Coating Remover”). In this case, conventionally, a large work space is required because it relies on manual work, and the method of applying the force at the time of removing the coating differs depending on the operator, and the optical fiber is broken or the coating is not completely removed. There was a drawback that Therefore, various methods for removing the coating using some kind of apparatus have been proposed (for example, Japanese Patent No. 1153354 “coating removing apparatus”, Japanese Patent Application No. 58-217371 “terminal forming apparatus for optical fiber”, No. 59-120641, "tape cable sheath removing device", etc., which individually treat a pair of optical fiber cores to be connected, one by one. , Japanese Patent Application No. 59-182471 "Automatic fusion splicer for optical fibers"), the drawback is that if two removing devices are prepared, the size of the entire device becomes large. However, there is a drawback that the operation time becomes long when the coating is sequentially removed.

To evacuate. Then, when the cutting edges of the cutting blades 41 and 42 are engaged with each other, the optical fiber of the optical fiber line is not cut, and only the coating is cut. Then, by moving the pair of coating gripping portions 2, 3 in the directions opposite to each other in the axial direction of the optical fiber core wires 1, 1 ', the coating of the optical fiber core wire can be removed as shown in FIG. The moving distance of the coating gripping portions 2 and 3 may be set according to the required length of coating removal. In the above-mentioned operation, if the coating gripping portions 2 and 3 are provided with a parallel drive unit (for example, a motor and a gear, a hydraulic or pneumatic cylinder), the coating gripping portions can be easily moved in the axial direction and in the opposite direction. be able to. Also,
The configuration of the gear allows the left and right grips to be driven simultaneously by one drive.
