本考案は光電スイツチの出力論理等を設定する
ためのスツチ構造に関する。[Detailed Description of the Invention] Industrial Application Field The present invention relates to a switch structure for setting the output logic, etc. of a photoelectric switch.
従来の技術

の検出出力によつて各種機器を制御する光電スイ
ツチが、工場の省力化等を目的として多用されて
いる。Prior Art A photoelectric switch is used in a factory to detect the presence or absence of a person or object based on whether or not light projected from a light emitting element is incident on a light receiving element, and to control various equipment based on the detection output. It is often used for the purpose of saving labor.
而して上記光電スイツチが検出する地点は、制
御すべき機器と離れている場合が多く、さらに検
出地点は設置面積が限られ雨やほこり等に晒され
易い等の悪環境下であることが多い。 However, the point detected by the photoelectric switch is often far away from the equipment to be controlled, and furthermore, the detection point has a limited installation area and is often in a poor environment, such as being easily exposed to rain or dust. many.
このため上記光電スイツチの一つのタイプとし

ルド線3をケース1外に引き出し、光電スイツチ
が制御する機器に接続できるようにしたものが開
発され使用されている。 For this reason, as one type of photoelectric switch, as shown in FIG. 6, a main body part 2 containing, for example, a light emitting/receiving element and its driving circuit is housed in a small sealed case 1, and power supply lines, output lines, etc. are enclosed. A system has been developed and used in which the shielded wire 3 is drawn out from the case 1 and can be connected to equipment controlled by a photoelectric switch.
ところで上記光電スイツチ4は、接続された制
御機器に合わせて出力論理を設定する必要があ
る。なお出力論理の設定とは、受光時に出力有、
遮光時に出力無とするか、又は受光時に出力無、
遮光時に出力有とするかの指定である。 By the way, it is necessary to set the output logic of the photoelectric switch 4 according to the connected control equipment. Note that the output logic setting means whether there is an output when receiving light, or
No output when light is blocked, or no output when light is received.
This specifies whether to output when light is blocked.
従来出力論理の設定は、ケース1から引き出さ
れたシールド線3内に出力論理切換用の信号線5
を設け、制御機器側でこの信号線5を“H”レベ
ル電位にするか“L”レベル電位にするかによつ
て行つていた。 Conventional output logic settings include a signal line 5 for output logic switching inside the shielded wire 3 drawn out from case 1.
This is done by setting the signal line 5 to an "H" level potential or an "L" level potential on the control equipment side.
而して上記光電スイツチ4の実際の使用状態を
考えると、検出地点と制御機器の間が、例えば

この場合には周辺電気機器が発生する電磁波によ
つて出力論理切換用の信号線5に誘導電圧が比較
的高い電圧レベルで発生し易く、信号線5の電位
を変え制御機器側で設定した出力論理とは異なつ
た出力論理で出力がされ、制御機器を誤動作させ
る場合があつた。 Considering the actual usage condition of the photoelectric switch 4, for example, the distance between the detection point and the control device is
The shield wire 3 is often long, with a distance of 10 m, in some cases up to 50 m to 100 m.
In this case, electromagnetic waves generated by the peripheral electrical equipment tend to generate induced voltage at a relatively high voltage level in the signal line 5 for switching output logic, and the potential of the signal line 5 is changed to set the output on the control equipment side. There were cases in which the output was output using an output logic different from the logic, causing the control equipment to malfunction.
このような不安定な動作を回避する手段として

論理切換用の短い専用線7をケース1から出力用
のシールド線3とは別に引き出し、光電スイツチ
の設置地点の近傍に設けた専用のスイツチ8で、
論理設定を行うこと等が考えられる。 As a means to avoid such unstable operation, for example, as shown in FIG. 7, a mechanical switch 6 such as a toggle switch or a slide switch is provided in the case 1 of the photoelectric switch, and a signal line 5 for switching the output logic is provided. Alternatively, as shown in Fig. 8, a short dedicated line 7 for logic switching can be drawn out from the case 1 separately from the shielded wire 3 for output, and a dedicated switch 8 can be installed near the installation point of the photoelectric switch. in,
It is possible to perform logical settings.
しかしながら前者機械式スイツチ6を設ける方
法は光電スイツチ自体が小型化されている現状で
は、その取付スペースを確保し難く、密閉性を損
なうことにもなるので、実用化には不適当であ

型コンパクト化及び取付の容易性によつて利用価
値がある上記光電スイツチ4の機能を若しく低下
させることになり、これまた実用化には不適当で
ある。 However, the former method of providing the mechanical switch 6 is not suitable for practical use, as photoelectric switches themselves are becoming smaller and it is difficult to secure mounting space and the sealing performance is impaired. In addition, the latter method of providing a short dedicated line 7 slightly degrades the function of the photoelectric switch 4, which is useful due to its compact size and ease of installation, and is also inappropriate for practical use. It is.
そこで本考案は上記誘導障害の問題、及び機械
