本発明は光ファイバをアーク放電により融着接続する
装置のファイバ移動機構に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fiber moving mechanism of an apparatus for fusion splicing optical fibers by arc discharge.
従来のこの種の融着装置は第１図に示すような構造に
なつていた。A conventional fusing device of this type has a structure as shown in FIG.

アーク放電を与える電極はファイバ軸心とＡ線の直交
する点に紙面垂直に一対向ある。A pair of electrodes for producing an arc discharge are arranged perpendicularly to the plane of the paper at a point where the fiber axis and the line A intersect at right angles.
なおテーパー状平板７は上下方向に、移動台４はファイ

が有る。 これを作動させるにはファイバを図のように
セットし、図示されないボタンを押すとモータ１２が回
転し、カム１１及びバネ２５によりストッパー６は下方
へ逃げる。Note that there is a sliding guide (not shown) so that the tapered flat plate 7 can be moved in the vertical direction and the movable table 4 can be moved in the longitudinal direction of the fiber. To operate this, the fiber is set as shown in the figure, and when a button (not shown) is pressed, the motor 12 rotates, and the stopper 6 escapes downward by the cam 11 and spring 25.
この時ファイバ移動台４はバネ２４で常にファイバ長手
方向（図中左向）に押されているのでストッパーにつけ

より左方へ前進する。両ファイバの端面間隔が１０〜３

更に移動台４は左方へ前進する。この前進開始と同時に
若干早く図示されない電極間で放電が行われファイバは
加熱されながら左方へ前進し１０〜３０μｍ押しこまれ
る。At this time, the fiber moving stage 4 is always pushed in the longitudinal direction of the fiber (leftward in the figure) by the spring 24, so when the tapered flat plate 7 attached to the stopper comes down, it is moved forward to the left by the follower 8. The distance between the end faces of both fibers is 10 to 3
When the distance reaches 0 μm, the arm 13 comes into contact with the tip of the micrometer head 14, and 8 and 7 become separated. Next, the motor 23 rotates, the decelerator 18 and the timing pulleys 17 and 15 rotate the micrometer head 14, and the movable table 4 further advances to the left. Simultaneously with the start of this forward movement, a discharge occurs a little earlier between the electrodes (not shown), and the fiber is heated while advancing to the left and being pushed in by 10 to 30 μm.

動台４が平行摺動であるため部品点数が多くなること、
ストッパー上下の運動と移動台４との動きが平板７を介
して行われるため、部品点数が多く且つ精度が低下する
ことなどの欠点があつた。When the micrometer head 14 rotates until the fiber is pushed in a predetermined amount, the cam 19 hits the limit 21, and the rotation of the motor 23 is stopped, and the pushing of the fiber is also stopped. Furthermore, when the discharge for a predetermined period of time is completed, the fiber is taken out by releasing the lock 5,5''. When a reset button (not shown) is pressed, the motor 12 rotates in the reverse direction, pushing up the stopper 6 and moving the moving table 4 to the right. At the same time, the motor 23 also rotates in the opposite direction, and when the micrometer head reaches the predetermined position, the cam 20 hits the limit switch 22 and stops.The same process can be repeated.This method is extremely accurate. Although it has the advantage of being able to perform precise positioning, the number of parts increases because the moving table 4 is sliding in parallel.
Since the movement of the stopper up and down and the movement of the movable table 4 are performed via the flat plate 7, there are disadvantages such as a large number of parts and a decrease in accuracy.
本発明はこれら２点の欠点を同時に解決せんとするもの
である。The present invention aims to solve these two drawbacks at the same time.
第２図は本発明の実施例を示す。FIG. 2 shows an embodiment of the invention.
被覆部の固定を行う４″，４″″は図のように固定用Ｖ
溝３，３″に対し斜めになつている。4″ and 4″″ for fixing the covering part are fixing Vs as shown in the figure.
It is oblique to the grooves 3 and 3''.

がマイクロメータヘッド１４にあたる。The operation is the same as that shown in FIG. 1, but the rotation of the motor 12'' turns the cam 1V, the stopper 6 is lowered by the protrusions 9'' and 8'', and the movable table 4'' rotates around the pin 27. Therefore, the fiber slides forward on 3 due to the rotational movement of the two parts. When the distance between the fiber end faces becomes 10 to 30 μm, the protrusion 8" deviates from the cam 1" and becomes the spherical protrusion 27".
corresponds to the micrometer head 14.
その後の動きは第１図と同じである。The subsequent movements are the same as in Figure 1.

でないので構造的に簡単であり安価である。Since the present invention has such a mechanism, the movable table is rotated by the pin 27 and is not parallel sliding as shown in FIG. 1, so the structure is simple and inexpensive.
加えて最初の動きが直接カム１「より与えられるので第
１図に示す従来の装置に比べ構造的に簡単で安価である
だけでなく、接触面が少ないことにより高精度である。In addition, since the initial movement is directly applied by the cam 1, it is not only structurally simpler and cheaper than the conventional device shown in FIG. 1, but also has high precision because there are fewer contact surfaces.
