る。However, since the light-receiving portion of the light-receiving element 2 is small, it is necessary to move and adjust the position of the light-receiving element 2 in order to ensure that the light-receiving portion receives the incoming light. Adjustment rod 4 is used. This adjusting rod 4
Is formed in a rod shape with a square cross section by using a metal material.

When the adjustment rod 4 is driven by moving in parallel to the direction of the arrow, that is, the direction orthogonal to the incident direction of light, the tip 4a pushes the side surface of the recess 3d when the portion that is exposed to the outside of the cylindrical body 1 is translated. As a result, the light receiving element holder 3 slides in the same direction, and accordingly, the light receiving element 2 also moves in the same direction to adjust the position. Further, in order to move the light receiving element 2 in the reverse direction, the adjustment rod 4 may be driven in the reverse direction as shown in FIG. 2 (b).

The groove width is formed to be sufficiently larger than the plate thickness of the adjusting rod 4, and the bottom surface thereof is provided with a plurality of recessed grooves 3e to which the tip 4a is just fitted. That is, in place of the concave portion 3d in the first embodiment, in the second embodiment, a plurality of concave grooves 3e having a width in the direction orthogonal to the incident direction smaller than that of the adjusting hole 1d of the cylindrical body 1 are provided. Will be there.

る。In such a position adjusting structure of the light receiving element, in any of the first and second embodiments,
The adjusting rod 4 is driven by an external force in a direction orthogonal to the incident direction of light for adjustment, that is, the method of parallel movement is used.Therefore, the adjusting hole 1d of the cylindrical body 1 has the tip 4a of the adjusting rod 4 mounted on the light receiving element holder. It is only an insertion hole for engaging the recess 3d of 3 and the size of the hole can be made sufficiently larger than the cross-sectional shape of the adjusting rod 4, so that the adjusting rod 4 can be easily moved from the adjusting hole 1d. Can be inserted and work is easy.

Since the adjustment hole 1d of 1 is a through hole that is sufficiently larger than the cross-sectional shape of the adjustment rod 4, when the adjustment rod 4 is inserted into the adjustment hole 1d, its tip 4a engages with the recess 3d of the light receiving element holder 3. The width of the recess 3d is formed to be slightly larger than the plate thickness of the adjusting rod 4 so that it does not take time to combine them. Therefore, the adjusting rod
There is a dimensional play between the tip 4a of 4 and the recess 3d, and rattling occurs when the driving direction of the adjusting rod 4 is reversed as shown in FIG. 2 (a) or (b). And it may be difficult to adjust.

業ができるものにもなる。According to the light-receiving element device of the present invention, when adjusting the position of the light-receiving element, the adjustment hole penetrating the cylindrical body is square and the light-receiving element holder is located at a position corresponding to the adjustment hole. Since the width of the recessed part provided in the direction orthogonal to the light incident direction is smaller than that of the adjustment hole, insert the adjustment rod with a square cross section through the adjustment hole and engage the tip part with the recessed part. Thus, it becomes possible to adjust the adjustment rod by translating it in a direction orthogonal to the incident direction of light. Therefore, unlike the conventional example, a special adjustment rod is not required, and for example, the tip portion is engaged with the concave portion. If you can use a familiar tool such as a flat-blade screwdriver as the adjustment rod and make the adjustment hole sufficiently larger than the cross-sectional shape of the adjustment rod, the adjustment hole is only an insertion hole for the adjustment rod. Insert the adjusting rod into the adjusting hole Without time-consuming to that, also to what can easily work.
