上動が規制されている。In the normal state, the operation plate 23 and the movable piece 29 are urged to rotate upward in FIG. 1 by the tension spring 34.
The operation plate 23 comes into contact with the push button 4 and its upward movement is restricted, and the movable piece 29 comes into contact with the upper part of the stopper portion 20 of the receiver 17 and its upward movement is restricted.
可動片２９に取付けた永久磁石３５は磁電変換素子１１
の正面でかつ最も近接した位置にあり、したがって磁電
変換素子１１は動作状態にある。The permanent magnet 35 attached to the movable piece 29 is the magnetoelectric conversion element 11
The magnetoelectric transducer 11 is located in front of and closest to the magnetoelectric transducer 11, and therefore is in an operating state.
ここで押ボタン４を押圧すると、操作板２３が受金１７

磁石３５が磁電変換素子１１から遠ざかるため、磁電変
換素子１１は非動作状態となる。When the movable piece 29 rotates by a certain angle, the movable piece 29 rotates around the hinge part 21 of the receiver 17 in the rotating direction in FIG.
Since the permanent magnet 35 attached to the movable piece 29 moves away from the magnetoelectric transducer 11, the magnetoelectric transducer 11 becomes inactive.

１１は再び動作状態となる。(Indicated by the dashed-dotted line in Figure 1). Next, when the pressing force on the push button 4 is released, the operation plate 23 is moved by the tension spring 34.
At the same time, the movable piece 29 rotates in the clockwise direction in FIG. 1, and the movable piece 29 also rotates in the first counterclockwise direction by snap action and comes into contact with the upper part of the stopper portion 20 of the receiver 17, and the magnetoelectric transducer 11 operates again. state.
上記動作において、動作特性上置も重要なのは可動片２
９のストローク規制である。In the above operation, the operating characteristics of the movable piece 2 are also important.
9 stroke regulations.
すなわち、本考案では、可動片２９が受金１７に設けた
Ｌ字形ストッパ部２０の上下間隙の間でのみ動作するこ
とができるので、可動片２９のストロークは正確に決定
され、高精度で安定した動作特性を得ることができる。That is, in the present invention, the movable piece 29 can operate only between the upper and lower gaps of the L-shaped stopper portion 20 provided on the receiver 17, so the stroke of the movable piece 29 is accurately determined and is highly accurate and stable. It is possible to obtain suitable operating characteristics.
なお、上記実施例においては、磁電変換素子１１と可動
片２９に取付けた永久磁石３５とで無接点スイッチ手段
を構成したが、永久磁石を電磁変換素子の正面に位置す
るようにケース１に固定するとともに、可動片を遮磁材
で構成し、この可動片の一端部で永久磁石と磁電変換素
子との間をさえぎるように構成してもよい。In the above embodiment, the non-contact switch means was configured by the magnetoelectric transducer 11 and the permanent magnet 35 attached to the movable piece 29, but the permanent magnet was fixed to the case 1 so as to be located in front of the electromagnetic transducer. In addition, the movable piece may be made of a magnetic shielding material, and one end of the movable piece may be configured to block the gap between the permanent magnet and the magnetoelectric conversion element.
また、無接点スイッチ手段を一対の投受光器で構成し、
これらを所定間隔をおいて対向配置し、これらの間に可
動片の一端部が出入りして遮光するようにしてもよい。In addition, the non-contact switch means is composed of a pair of light emitters and receivers,
These may be arranged facing each other at a predetermined interval, and one end of the movable piece may go in and out between them to block light.
さらに、受金１７のストッパ部２０としては上記実施例
のごとくＬ字形のものに限らず、たとえば可動片の端部
を所定ストロークだけ移動可能に挿通するわけであって
もよい。Furthermore, the stopper part 20 of the receiver 17 is not limited to the L-shape as in the above embodiment, but may be one in which the end of a movable piece is inserted so as to be movable by a predetermined stroke.
以上の構成で明らかなように、本考案によれば受金を一
枚板で構成したので、単なるプレス加工でも高い寸法精
度を得ることが可能となり、とくに可動片のストローク
を上記受金のストッパ部の間隙のみで決定できるので、
高精度かつ長期間に亙って安定した動作特性を得ること
ができる。As is clear from the above configuration, according to the present invention, since the receiver is constructed from a single plate, it is possible to obtain high dimensional accuracy even with simple press processing, and in particular, the stroke of the movable piece can be adjusted by adjusting the stroke of the movable piece to the stopper of the receiver. Since it can be determined only by the gap between the parts,
High precision and stable operating characteristics can be obtained over a long period of time.
また、可動片のストロークは金属製受金で規制されるの
で、長期間使用しても摩耗することがない。Furthermore, since the stroke of the movable piece is regulated by a metal holder, it will not wear out even after long-term use.
また、組立てにあたって、受金と操作板と可動片と引張
スプリングとからなる駆動部を予め一体的に組立てるこ
とができるので、駆動部単体で動作試験することができ
ると共に、駆動部は受金をケースに固定するのみでケー
ス内に組込むことができるので、組立てやすく工数を低
減することができる。In addition, during assembly, the drive unit consisting of the receiver, operation plate, movable piece, and tension spring can be assembled in advance, so the operation of the drive unit itself can be tested; Since it can be assembled into the case by simply fixing it to the case, assembly is easy and the number of man-hours can be reduced.
さらに、操作板はその他端が受金の他端部の開口部に挿
入されているため、このスイッチに振動や衝撃が加わっ
たとき操作板の横振れが防止され、操作板の動作の安定
性が増す。Furthermore, the other end of the operation plate is inserted into the opening at the other end of the holder, which prevents the operation plate from swinging laterally when vibrations or shocks are applied to the switch, increasing the stability of operation of the operation plate. increases.
