る。In recent years, with the spread of various office automation equipment such as personal computers and word processors, many devices that use keyboards as input devices are installed in the same room, and many operators are often operating keyboards at the same time. As input speeds continue to increase, the sound of key switches has become a problem, and there is a strong need to reduce the number of recovery stations for push button switches used in keyboards.
〔従来の技術］

くに遊嵌された状態になっている。A housing 2' is made of, for example, a cylindrical resin molded product having a hollow inner hole, and a housing stopper part 21' consisting of a step is provided in the middle part. The slider 1 is inserted into the hollow inner hole by an appropriate method, for example, by providing a slit in the cylindrical portion of the slider 1' and squeezing the tip of the slider 1' during insertion. When the insertion pushing and narrowing force is released, the tip of the slider 1'' expands, and the slider stopper section 11'' and the housing stopper section 21'' engage with each other to prevent them from coming off and are loosely fitted so that they can slide up and down. It has become.
３は弾性体アクチュエータで、たとえば、シリコーンゴ

けた絶縁フィルムを間に挟んで重ねて形成されている。The contact element section 41 is constructed by, for example, stacking two upper and lower contact electrode wiring films (membranes) 4 in which contacts are printed in a matrix on a plastic film, with an insulating film having holes made only for the contact sections sandwiched between them. It is formed by
５はサバ−ドパネルで。5 is a Sabado panel.

ついては省略しである。Note that the drawings are simplified to the extent that the basic configuration can be understood, and therefore details that are not directly related to the present invention are omitted.
（発明が解決しようとする課題〕
一般に、押釦スイッチにおいてはキータッチ時のキー操
作音は、主としてキー押下時とキー復旧時に発生する。(Problems to be Solved by the Invention) In general, in a push-button switch, key operation sound when a key is touched is mainly generated when the key is pressed and when the key is restored.
最近、低背型のキーボードに広く用いられるようになっ
た前記従来例（第３図）で説明した。いわゆる、メンブ

下時に比較してキー復旧時に発生するキー操作音の方が
溝かに大きい。The conventional example (FIG. 3), which has recently become widely used in low-profile keyboards, has been described. In so-called push-button switches for membrane keyboards, the key operation sound generated when a key is restored is much louder than when a key is pressed.
第４図は従来の押釦スイッチのキー復旧音発生を説明す

丁度釣鐘の作用を果たして反響し、その結果、大きなキ
ー復旧台を生じるからである。That is, when pressed, the elastic actuator 3, for example,
While the dome-shaped silicone rubber acts as a buffer material, when the key is restored, the slider 1' jumps upward due to the recovery recoil force of the dome-shaped rubber, and the slider stopper part 11' becomes the housing stopper part 21'. This is because the collision generates an impact sound, and the hollow inner hole of the housing 2' acts as a bell and reverberates, resulting in a large key recovery stand.
したがって、キースイッチ復旧台がオペレータは勿論の
こと、その周辺の人々に不快感を与えるという問題があ
り、その解決が必要であった。Therefore, there is a problem in that the key switch recovery table causes discomfort not only to the operator but also to people around the key switch, and a solution to this problem is needed.

復旧音を著しく低減することが可能となる。According to the present invention, since a plurality of slits 22 are provided in the side wall of the cylinder having a hollow inner hole of the housing 2, even if the slider stopper part 11 collides with the housing stopper part 21 during key recovery, the Impact force is slit 22
The bell is absorbed by and weakened by the low-frequency vibrations of the plurality of tongues 23 separated by the bell, and the bell is broken, reducing the echo in the inner hole of the housing 2, and thus producing the key recovery sound. It becomes possible to significantly reduce the amount.
第１図は本発明実施例の構造を説明する断面図である。 FIG. 1 is a sectional view illustrating the structure of an embodiment of the present invention.

く低減可能となった。In this embodiment, since a plurality of slits 22 are provided in the side wall of the cylinder having a hollow inner hole of the housing 2, even if the slider stopper part 11 collides with the housing stopper part 21 when the key is restored, the impact force will be is absorbed by the low-frequency vibrations of the plurality of tongues 23 separated by the slits 22 and is weakened, and the bell is broken and the echo in the inner hole of the housing 2 is reduced, allowing the key to be recovered. The sound can be significantly reduced to less than half of the approximately 70 decibels of conventional push-button switches.
本実施例では、スライダストッパ部１１とハウジングス
トッパ部２１をそれぞれの側壁に傾斜させて設け、衝撃
をできるだけ弱めるようにしである。In this embodiment, the slider stopper part 11 and the housing stopper part 21 are provided on their respective side walls at an angle so as to weaken the impact as much as possible.
なお、スリット２２は実施例のようにハウジング２の上
端開口部まで切り込まれている必要は必ずしもなく、細
長い穴状のものでも、さらに、円形や角形の穴であって
も有効である。Note that the slit 22 does not necessarily have to be cut all the way to the upper end opening of the housing 2 as in the embodiment, and it is also effective to have an elongated hole shape, or even a circular or square hole.

きい。As described above, according to the present invention, since the plurality of slits 22 are provided in the side wall of the cylinder having the hollow inner hole of the housing 2, the slider stopper part 1 is
Even if the bell 1 collides with the housing stopper part 21, the impact force is weakened, and the bell is broken and no echo is generated. Therefore, it is possible to significantly reduce the key recovery sound, and the performance of the push button switch is improved. This greatly contributes to improvements in the quality and performance of the keyboards that use them.
