Abstract
(EN)
A capacitive sensor exhibiting good operability in which wrong operation is suppressed. Switches (SW1-SW4) are formed between a displacement electrode (40), and switch electrodes (E11-E14) held at a predetermined potential and earthed switch electrodes (E15-E18). Electrodes (E1-E5) for constituting capacitive elements between the electrodes (E1-E5) and the displacement electrode (40) are connected with switches (SW11-SW15), respectively. A judging circuit judges the states of the switches (SW1-SW4). When at least one of the switches (SW1-SW4) is turned off, a period signal is inputted only to the electrodes (E1-E4) for capacitive elements corresponding to the X-axis direction and Y-axis direction and when all the switches (SW1-SW4) are turned on, the period signal is inputted only to the electrode (E5) for capacitive element corresponding to the Z-axis direction.

L'invention concerne un capteur capacitif montrant une bonne efficacité fonctionnelle dans lequel tout mauvais fonctionnement est supprimé. Des commutateurs (SW1 à SW4) sont formés entre une électrode de déplacement (40) et des électrodes de commutation (E11 à E14) maintenues à un potentiel prédéterminé ainsi que des électrodes de commutation mises à la masse (E15 à E18). Des électrodes (E1 à E5), destinées à constituer des éléments capacitifs entre les électrodes (E1 à E5) et l'électrode de déplacement (40), sont respectivement reliées à des commutateurs (SW11 à SW15). Un circuit d'évaluation juge des états des commutateurs (SW1 à SW4). Lorsqu'au moins l'un des commutateurs (SW1 à SW4) est mis hors circuit, un signal périodique n'est appliqué en entrée que sur les électrodes (E1 à E4) pour des éléments capacitifs correspondant au sens de l'axe des X et au sens de l'axe des Y, et lorsque tous les commutateurs (SW1 à SW4) sont mis en circuit, le signal périodique n'est appliqué que sur l'électrode (E5) pour l'élément capacitif correspondant à le sens de l'axe des Z.

 操作性がよく、誤操作の少ない静電容量式センサを提供する。  変位電極40と、所定電位に保持されたスイッチ用電極E11~E14及び接地されたスイッチ用電極E15~E18との間には、スイッチSW1~SW4が形成されている。また、変位電極40との間で容量素子を構成する容量素子用電極E1~E5には、スイッチSW11~SW15がそれぞれ接続されている。判定回路では、スイッチSW1~SW4の状態が判定される。スイッチSW1~SW4の少なくとも1つがオフ状態である場合には、X軸方向及びY軸方向に対応した容量素子用電極E1~E4にだけ周期信号が入力され、スイッチSW1~SW4の全てがオン状態である場合には、Z軸方向に対応した容量素子用電極E5にだけ周期信号が入力される。
