Description
上記課題を解決するため、本発明は、請求項１に記載されているように、人体を被検知体とする検知電極板と、上記検知電極板の裏面側に所定の間隔をもって配置された接地電位を有するグランド電極板と、上記検知電極板と上記グランド電極板との間に電気絶縁材を介して配置されたガード電極板とを含み、上記検知電極板と上記ガード電極板とが同電位に保たれており、上記各電極板が電気絶縁性の扁平なカバー内に収納されている近接センサにおいて、
上記ガード電極板は上記グランド電極板の全面を覆う面積を有し、上記検知電極板の面積は上記ガード電極板の面積よりも小さく、上記ガード電極板上の上記検知電極板が存在していない部分には、上記グランド電極板に電気的に接続されたグランド電極引出板が上記検知電極板と電気的に絶縁された状態で並設されていることを特徴としている。
In order to solve the above-described problems, the present invention provides a detection electrode plate having a human body as a detection object and a grounding disposed at a predetermined interval on the back side of the detection electrode plate as described in claim 1. A ground electrode plate having a potential, and a guard electrode plate disposed between the detection electrode plate and the ground electrode plate via an electrical insulating material, wherein the detection electrode plate and the guard electrode plate have the same potential. In the proximity sensor in which each electrode plate is housed in an electrically insulating flat cover,
The guard electrode plate has an area that covers the entire surface of the ground electrode plate, the area of the detection electrode plate than the area of the guard electrode plate rather small, the detection electrode plate on said guard electrode plate is present The ground electrode lead plate electrically connected to the ground electrode plate is juxtaposed in a state where it is electrically insulated from the detection electrode plate.
