In this case, an engineer or the like needs to control the device from various directions. However, the light receiving section that receives the transmitted light originally has directivity, and in order to eliminate this, a plurality of light receiving sections are provided to broaden the directivity.

恐れがある。C. Problems to be Solved by the Invention However, to have a plurality of light-receiving parts requires not only simply increasing the number of light-receiving elements but also matching the impedances of the light-receiving elements. Therefore, it is necessary to add a circuit, which not only increases the cost of the device, but also complicates the circuit, which may reduce the reliability.

That is, on the optical axis surface of the light receiving surface, a reflector for reflecting transmitted light from the surroundings to the light receiving surface is provided, and the reflector is a conical mirror, and its apex is concentric with the optical axis. Is directed to the light receiving surface.

台３は上部の円環3aと脚3bからなる。F. Example Hereinafter, an embodiment of the present invention will be described based on an example shown in the drawings. In FIG. 1, a reflector 2 is provided on a vertical optical axis 1b of an upward light-receiving surface 1a of the light-receiving unit 1 via a support base 3 for reflecting transmitted light from around the light-receiving surface 1a. The reflector 2 is a conical mirror made of white acrylic resin, and its apex is placed on the support base 3 concentrically with the optical axis and directed toward the light receiving surface. The support base 3 comprises an upper ring 3a and legs 3b.
従って、光軸1b回りの360度の範囲からの送信光は反
射体２で反射されて受光部1aに至る。Therefore, the transmission light from the range of 360 degrees around the optical axis 1b is reflected by the reflector 2 and reaches the light receiving portion 1a.
第２図は支持台の他の実施例を示し、透明円筒体４か
らなる。FIG. 2 shows another embodiment of the support base, which comprises a transparent cylindrical body 4.
第３図は更に他の実施例５を示し、透明短円柱体5aの
上端面が円錐面5bを持って凹んでいる。この円錐面に銀
などの反射用膜が付着される。FIG. 3 shows still another embodiment 5, in which the upper end surface of the transparent short cylindrical body 5a is recessed with a conical surface 5b. A reflection film such as silver is attached to this conical surface.

ば、指向性の範囲が可変となる。The phantom line drawing in FIG. 1 shows still another embodiment, in which the annular concave reflector 6 is concentric with the optical axis 1b and is provided below the conical reflector 2. This gives upward directivity. Further, if the height of the concave reflector 6 is made variable, the range of directivity becomes variable.
前記円錐反射体２の代わりに、頂部を切除したもので
もよい。また、64角錐などの正多角錐でもよい。Instead of the conical reflector 2, the top may be cut off. Alternatively, a regular polygonal pyramid such as a 64-sided pyramid may be used.
