用状態を説明する。Knife part 1 of deburring ring 3? is in close contact with the fiber 1, but its inner surface widens upward at an angle θ as shown in the figure, and escapes far from the outer periphery of the fiber 1, creating a loosely fitted state. Also, this deburring ring 3
The outer periphery of the burr ring 3 is slidably fitted to the inner periphery of the cylindrical guide 5, so that the burring ring 3 slides in the axial direction of the introduction hole 9, and the side opposite to the knife part 10 is fitted with the anti-squeezing strip 4. and is supported on the introduction hole 9 side. The knife portion 10 is adapted to come into contact with the mirror surface of the sliding mirror plate 6 and press it. The usage status will be explained below.

挿通せしめ、ファイバー１の先端部をナイフ部１０より
端面の仕上げシロδを突出せしめる。As shown in FIG. 4, the fiber 1 is fitted into the introduction hole 9 and introduced into the cylindrical guide 5, and the burring ring 3 is inserted through it, and the tip of the fiber 1 is cut through the knife part 10 by the finishing margin δ of the end surface. Make it stand out.

As shown in the figure, a mirror plate 6 is heated by a heating device 7 which is a heater.
The mirror surface of the fiber 1 is heated to a temperature higher than the melting point of the fiber 1, and the mirror surface plate 6 is slid and pressed in the direction of the end surface of the fiber 1 within the cylindrical guide 5 to finish the end surface into a smooth mirror surface.

し第５図に示す如くナイフ部１０の外周にバリ８を発生
せしめる。The anti-squeezing strip 4 supports the deburring ring 3 by this pressing.
Since it will shrink slightly, this shrinkage margin δ2 will also become the finishing margin. At this time, the finishing margin δ1 is melted and a burr 8 is generated on the outer periphery of the knife portion 10 as shown in FIG.

出すごとく切除する。Next, as shown in FIG. 6, the mirror surface of the mirror plate 6 is cooled by a cooling device 11 made of a cold water pipe, and after the end face of the fiber 1 has been sufficiently cooled, the mirror plate 6 is slid back toward the side opposite to the fiber 1, and the burr is cut off. The ring 3 is pushed down by the anti-shrunk strip 4, and the burr 8 generated up to the finishing margin δ2 is cut off as if pushed out from the end of the fiber 1.

仕上がる。(4) Effects of the present invention According to the present invention, the fiber 1 is fitted and inserted through the introduction hole 9 to align with the axial direction of the cylindrical guide 5, and the mirror surface of the mirror plate 6 is aligned with the axis of the cylindrical guide 5. Since they are fitted so that they can move forward and backward at right angles to the direction, the mirror surface is pressed at right angles to the axial direction of the fiber 1, and the end face of the fiber 1 is finished at right angles to the axis.

失が防止されｊるのである。In addition, when the specular plate 6 is retreated from the end face of the processed fiber 1, the knife portion 10 of the burr cutting ring 3 pushed out from the anti-shrinking strip cuts off the generated burr 8, so that the burr 8 is left on the end face of the fiber 1. This results in a clean finish without leaving any traces, and as a result, connection loss in the amount of light transmitted when one fiber is spliced is prevented.
