この発明はプラスチツク製光フアイバーの切断
端部を平滑化するために使用する光フアイバーの
端面処理ヒーターに関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an optical fiber end face treatment heater used for smoothing the cut end of a plastic optical fiber.

As shown in Figure 1, a heater 2 is placed on the back side of the glass plate 1.
A current is applied to the glass plate 2 to heat the surface of the glass plate 2, and the end face of a cut plastic optical fiber (not shown) is pressed against the surface to melt and smooth it, and if the end faces are bonded well. Fiber optic end face heaters used for cooling have recently been developed. In the drawings, 3 is a heater electrode, and 4 is a heater power source.
而してこのヒーターはガラス板１の表面に傷が
つくと押圧溶融せしめる光フアイバーの端面の仕
上りが良好とならない。 In this heater, if the surface of the glass plate 1 is scratched, the finish of the end face of the optical fiber which is pressed and melted will not be good.
この発明は上記の点に鑑みてなされたもので、
光フアイバーの端面を押圧溶融せしめるガラス板
に生じる傷の発見を容易にするものである。
This invention was made in view of the above points,
This makes it easier to find scratches that occur on the glass plate that presses and melts the end face of the optical fiber.

The gist of this invention is to provide an optical fiber end face treatment heater in which a heater 2 is placed on the back surface of a smooth glass plate 1, and a current is applied to the heater 2 to heat the surface of the glass plate 2. This is an optical fiber end face treatment heater in which a light emitting diode 5 is directed toward the center of the glass plate 2 and arranged so that light entering the inside of the glass plate 2 is totally reflected on the front and back surfaces of the glass plate 2.
第１図及び第２図に示すのはこの発明の一実施
例で、略円形の表裏面及び端面の平滑なガラス板
１の中央の裏面に略円形の箔状ヒーター２を配置
し、かつ、一側端部に光が端面に斜めに入るよう
に発光ダイオード５を配置したものである。 FIG. 1 and FIG. 2 show an embodiment of the present invention, in which a substantially circular foil heater 2 is arranged on the central back surface of a glass plate 1 having a substantially circular front and back surface and smooth end surfaces, and A light emitting diode 5 is arranged at one end so that light obliquely enters the end face.
ヒーター２は電極３間に通電することにより発
熱される。 The heater 2 generates heat by passing electricity between electrodes 3.
而して発光ダイオード５を点灯すると光はガラ
ス板２の側面より内部に入り表裏面でつづれ折り
に全反射しつつ内部を通過する。そしてこの際、
ガラス板２の表面に傷６があると、この部分で光
が全反射せず、ガラス板２の表面にもれ出てく
る。この光は肉眼により容易に検出できるので、
傷の生じていることもすぐにわかるのである。 When the light emitting diode 5 is turned on, the light enters the inside of the glass plate 2 from the side surface and passes through the inside while being totally reflected in a winding manner on the front and back surfaces. And at this time,
When there is a scratch 6 on the surface of the glass plate 2, light is not totally reflected at this part and leaks onto the surface of the glass plate 2. This light is easily detected by the naked eye, so
You can immediately see that a wound has occurred.
以上のようにこの発明による光フアイバーの端
面処理ヒーターはガラス板の一側端部に配置した
発光ダイオードを点灯するのみで、ガラス板内部
からもれ出る光があることにより表面に傷がある
ことを知ることができるのである。
As described above, the optical fiber end face treatment heater according to the present invention only lights up the light emitting diode placed at one end of the glass plate, and the surface may be scratched due to light leaking from inside the glass plate. It is possible to know.
