より封止する構造となっていた。As shown in Figures 5(a) and 5(b), conventional photodetectors are made by mounting and bonding a photodetector pellet on a lead, metal base, or ceramic base horizontally or vertically with respect to the lead reference line, and then attaching it to a resin or ceramic base. It was designed to be sealed with a glass cap.
受光素子にはリード方向に対し横方向に受光する横受光

示す。倒れの構造においても受光方向は受光ペレットに
対し垂直方向からである。There are two types of light-receiving elements: a horizontal-receiving type that receives light in the horizontal direction with respect to the lead direction, and a vertical-receiving type that receives light in the vertical direction. As shown in Figure (b), even in the tilted structure, the light receiving direction is perpendicular to the light receiving pellet.

図の様にリード成形にて対応する必要があった。Conventionally, even if the required characteristics of light-receiving elements are the same, the usage, structure of the place of use, and mounting method vary depending on the purpose, as shown in Figure 6 (a).
, As shown in (b), it was necessary to select either a horizontal reception type or a vertical reception type. In other words, when the substrate is horizontal to the light from the lateral direction, it is necessary to select and use a horizontal light-receiving type element as shown in Fig. 6 (al), and when the board is vertical, it is necessary to select and use a vertical light-receiving type element.Similarly, Even when changing the structure of the area where it is used, it may be necessary to switch from the horizontal receiving type to the vertical receiving type, or from the vertical receiving type to the horizontal receiving type, or else the seventh
As shown in the figure, it was necessary to respond with lead molding.

響を考慮せねばならぬといった煩雑さがあった。Depending on the mounting method or changes therein, there is a drawback that even if the required characteristics are the same, the same product cannot meet the requirements. Furthermore, when dealing with lead molding, there is the complication of having to consider the associated man-hour costs and the impact on the product during lead molding.
本発明の目的は同一の受光素子で横受光型及び縦受光形

にある。The purpose of the present invention is to enable the same light receiving element to be used for both horizontal and vertical reception types, and as long as the required characteristics are the same, the purpose of the invention, the structure of the location of use, and the mounting method can be adjusted regardless of the differences in usage, structure, and mounting method. It is an object of the present invention to provide a light receiving element that can be used without changing the element.

いった特徴を有している。[Means for Solving the Problems] The light-receiving element of the present invention has a structure in which the light-receiving pellet inside the seal is installed at an angle with respect to the lead reference line, making it possible to receive light from two directions with the same optical characteristics. are doing. Therefore, the same light-receiving element can be used for both horizontal and vertical light-receiving types, and as long as the required characteristics are the same, the application, the structure of the location of use, and the mounting method can be used regardless of differences in the method or change. It has the characteristic that it is possible.
次に、本発明の実施例について図面を参照して説明する

向性といった光学的特性が等しくなっている。In FIGS. 1 and 2, a light-receiving pellet 1 is mounted on a lead 2, bonded, and then sealed with a resin 3. Since the mounting island 4 of the lead 2 has an inclined structure, the light-receiving pellet 1 is set at an angle of 45 degrees with respect to the lead reference line 5, and the light-receiving sensitivity in the horizontal direction 30 and the vertical direction 20, The optical characteristics such as directivity are the same.
また、受光ペレットを傾けて設置しているため、同様の
ペレットを使用した従来の受光素子と比べた場合、その
感度が減少してしまうため、受光面にレンズ６を設ける
ことにより補正している。Additionally, since the light-receiving pellet is installed at an angle, its sensitivity decreases when compared to a conventional light-receiving element using a similar pellet, so this is corrected by providing a lens 6 on the light-receiving surface. .
上記実施例に示したように、本発明によれば、横方向、
縦方向とも同等の光学的特性にすることが可能となる。As shown in the above embodiments, according to the present invention, in the lateral direction,
It becomes possible to have the same optical characteristics in the vertical direction as well.

There is no need to select a vertical light-receiving element, and the same light-receiving element 7 can be used in the vertical direction in the tub shown in FIGS.

る。It can correspond to the board 14 in the direction. Therefore, if the installation method changes due to a design change, for example, from a horizontal receiving type,
Even when it is necessary to transform to a vertical light receiving type, it is possible to do so with the same light receiving element and without lead molding, and there is no need to consider the man-hour cost required for lead molding or the impact on the product. Furthermore, in combination with a light emitting element, application to a special photointerrupter as shown in FIG. 4 can be considered.
