ド２〜５の変形が生じ易い。Problems to be Solved by the Invention By the way, in the conventional photocoupler described above, lead forming is applied to the leads 2 to 5 protruding from the case 1, and this lead forming allows each lead 2 to 5 to be connected to a light emitting element and a light receiving element. A lead lead-out portion extending from each of the main bodies and a lead bent portion extending bent in the length direction of the lead lead-out portion are formed. In this case, since the leads 2 to 5 extending from the case 1 are long and bent, the leads 2 to 5 deform even if they receive a small external force. Moreover, since the leads 2 to 5 protrude outward to a large extent and are located in positions where they are likely to come into contact with the surroundings, deformation of the leads 2 to 5 is likely to occur.

来す。 When storing or handling the photocoupler after performing the lead forming described above, if the leads 2 to 5 are deformed by some external force, the printed circuit board 8
The leads 2 to 5 of the photocoupler cannot be smoothly inserted into the through hole 9 formed in the hole 9, which hinders the work of attaching the photocoupler to the printed circuit board.

る。 Further, in the conventional photocoupler, even after lead forming, the leads largely protrude outward from both ends of the photocoupler. Therefore, conventional photocouplers require a large area on a printed circuit board, which hinders the realization of high-density mounting on a printed circuit board.
そこで本考案の目的は、リードが変形しにくく
かつ小形化が可能なホトカプラを提供することを
目的とする。 Therefore, an object of the present invention is to provide a photocoupler whose leads are not easily deformed and whose size can be reduced.

記ケースの外部に導出される。Composition of the Invention The present invention includes a cylindrical case in which an internal cavity is formed, and a case in which the optical fibers are arranged facing each other on substantially the same optical axis within the internal cavity in an optically coupled state, and are each led out to the outside of the case. A photocoupler comprising a pair of light-emitting element and light-receiving element each having a lead, and a pair of closing members for closing an opening of an internal cavity of the case outside the bodies of the light-emitting element and light-receiving element, wherein the lead is It consists of a lead lead-out part extending from each of the main bodies of the light-emitting element and the light-receiving element, and a lead bending part extending bent in the length direction of the lead-out part, and the lead lead-out part of the lead of the light-emitting element and the light-receiving element. Lead lead-out portions of the leads extend in opposite directions, and bent lead portions of the leads of the light emitting element and bent portions of the leads of the light receiving element extend in the same direction;
The case has notches at the end of the opening, and the lead bent portions are led out of the case from these notches.
作 用
リード屈曲部はケースの切込み部から外部に導

確に決定される。Operation Since the lead bending portion is led out from the notch in the case, the direction and spacing of the leads can be determined relatively accurately.

実装作業中に、リードの変形が起こり難い。 Since the distance between the lower end of the case and the tip of the lead is within a predetermined range, the length of the lead extending from the case is shortened compared to the conventional case. Further, the lead lead-out portion, on which a bending moment is likely to act when an external force is applied from the tip of the lead in the direction in which the bent portion of the lead extends, does not protrude to the outside of the case and the closing member. Moreover, since the structure does not allow the leads to protrude from both sides of the case, the leads are less likely to hit the surrounding area than in the past. For these reasons, deformation of the leads is unlikely to occur during the production, storage, transportation, and mounting of photocouplers on printed circuit boards.
更に、ケースの両側にリードを突出させない構
造であるため、ホトカプラの全長ｌが短縮される
（ｌ＜Ｌ）。 Furthermore, since the structure does not allow the leads to protrude from both sides of the case, the total length l of the photocoupler is shortened (l<L).
