いという欠点がある。A conventional interrupter is shown in FIG. 1, and a sectional view thereof is shown in FIG. 2. Conventionally, in an interrupter, a light emitting element 1 and a light receiving element 2 are assembled separately and sealed with a translucent resin, and then a light emitting device 4 and a light receiving device 5 are placed in a case 3 made of a non-transparent resin. It is formed by inserting and fixing the elements so as to face each other, and fitting the stopper 6 into the case. Therefore, when putting the light emitting device 4 and the light receiving device 5 into the case 3, it takes a lot of man-hours and is expensive. Furthermore, since the elements are opposed to each other, there is a drawback that the external terminal 7 has a thick outer shape.

ース１０を接着してインタラプタとする。The present invention will be explained below using examples. FIG. 3 is a sectional view of the interrogator according to the present invention, and FIG. 4 is an explanatory diagram of assembly. A light emitting element 1 and a light receiving element 2 are mounted on a lead frame 8.
are mounted alternately, wire bonding is performed, and the light-emitting element and the light-receiving element are integrally resin-sealed with a translucent resin 9. At this time, the surface of the translucent resin facing the element surface and the element surface are formed at an angle of 45 degrees, so that the light emitted from the light emitting element is reflected and reaches the light receiving element. The resin-sealed outer shape and the light-shielding case 10 that fit together are glued together to form an interrupter.
この様に本発明によれば、従来に比べ安価に製造出来る
。しかも、外部端子が一直線上に並んでいるＳＩＰ型で
あるので薄型になシ、かつ実装時の占有面積を狭く出来
るという長所がある。As described above, according to the present invention, it can be manufactured at a lower cost than in the past. Moreover, since it is of the SIP type in which the external terminals are arranged in a straight line, it has the advantage of being thin and occupying a small area when mounted.

用すれは伝達効率が良くなることはもちろんである。In the present invention, the surface of the translucent resin facing the element surface is
Although an example in which the element is tilted at an angle of .degree. is used, it goes without saying that the transmission efficiency will be improved if a paraboloid is used with the element as the focal point.
