Description

本発明は、スイッチ本体を押圧操作する押ボタン部を、アダプターを用いて該スイッチ本体に対応した大きさよりも大型化するようにした押ボタンスイッチ装置に関するものである。   The present invention relates to a push button switch device in which a push button portion for pressing a switch body is made larger than a size corresponding to the switch body using an adapter.

薄型の押ボタンスイッチ装置としては、例えば特許文献1に記載の押ボタンスイッチ装置が提案されている。   As a thin pushbutton switch device, for example, a pushbutton switch device described in Patent Document 1 has been proposed.

ところで、近年、操作の利便性の向上から押ボタンスイッチ装置の操作面を大型化することが要請されている。そこで、図21及び図22に示す押ボタンスイッチ装置が提案されている。この押ボタンスイッチ装置は、既存の薄型の押ボタンスイッチ装置を共用して、押ボタン部のみを大型化したものである。即ち、この押ボタンスイッチ装置は、押ボタン部を保持する操作体70をスイッチ本体2から上方に大きく張り出した形状とし、この操作体70にスイッチ本体2に対応した本来の大きさよりも大型化した押ボタン部72を装着したものである。なお、図21及び図22において、Mは化粧板、Nは取付パネルである。   Incidentally, in recent years, there has been a demand for increasing the operation surface of the push button switch device in order to improve the convenience of operation. Therefore, a push button switch device shown in FIGS. 21 and 22 has been proposed. This push button switch device shares the existing thin push button switch device and enlarges only the push button portion. In other words, the push button switch device has a shape in which the operating body 70 that holds the push button portion is greatly projected upward from the switch body 2, and the operating body 70 is larger than the original size corresponding to the switch body 2. A push button 72 is attached. 21 and 22, M is a decorative board, and N is a mounting panel.

しかしながら、上記従来例では、操作面の大型化は達成されるけれども、操作体70が大きく上方に張り出した形状であることから、薄型化が満たされないという問題が生じる。そこで、従来から既存の薄型の押ボタンスイッチ装置を共用し、しかも、操作面の大型化及び薄型化を満たす押ボタンスイッチ装置が要望されていた。   However, in the above-described conventional example, although the size of the operation surface is increased, there is a problem that the thinning cannot be satisfied because the operation body 70 has a shape that protrudes greatly upward. Therefore, there has been a demand for a push button switch device that shares the existing thin push button switch device and satisfies the increase in size and thickness of the operation surface.

本発明は、上記の実情を鑑みて考え出されたものであり、その目的は、操作面の大型化及び薄型化を満たす押ボタンスイッチ装置を提供することである。   The present invention has been devised in view of the above circumstances, and an object of the present invention is to provide a push button switch device that satisfies an increase in size and thickness of an operation surface.

上記目的を達成するために本発明のうち請求項1記載の発明は、スイッチ本体を押圧操作する押ボタン部を、アダプターを用いて該スイッチ本体に対応した大きさよりも大型化するようにした押ボタンスイッチ装置であって、前記スイッチ本体は、前記押ボタン部の下方に配設されるとともに、スイッチ本体ケースと、スイッチ本体ケース内に配設され押ボタン部の押圧操作、操作解除に連動して上下に移動可能であり且つ上向きに付勢されている操作体と、スイッチ本体ケース内に配設され操作体の下動によりオン又はオフに切り換わるスイッチ部とを備え、前記アダプターは、スイッチ本体の外周面に沿って上下に移動可能であって、押ボタン部が載置される底面部と、底面部の外側周縁部に一体的に形成され押ボタン部をガイドするガイド部と、底面部の内側周縁部に一体的に形成されスイッチ本体を外装する筒状部とを備えたことを特徴する。   In order to achieve the above object, the invention according to claim 1 of the present invention is such that the push button portion for pressing the switch body is made larger than the size corresponding to the switch body using an adapter. A button switch device, wherein the switch body is disposed below the push button portion, and is interlocked with a switch body case and a push operation of the push button portion disposed within the switch body case and an operation release. An operating body that can be moved up and down and biased upward, and a switch portion that is disposed in the switch body case and is turned on or off by a downward movement of the operating body, and the adapter includes a switch It is movable up and down along the outer peripheral surface of the main body, and is formed integrally with the bottom surface portion on which the push button portion is placed and the outer peripheral edge portion of the bottom surface portion to guide the push button portion. Features and de unit, further comprising a cylindrical portion for sheathing a switch body formed integrally with the inner periphery of the bottom portion.

上記構成によれば、押ボタンスイッチ装置の厚みを従来例に比べて小さくできる。なお、この理由については、以下の発明を実施するための最良の形態の項における本発明の概念において詳述している。   According to the said structure, the thickness of a pushbutton switch apparatus can be made small compared with a prior art example. This reason is described in detail in the concept of the present invention in the section of the best mode for carrying out the invention below.

また請求項2記載の発明は、請求項1記載の押ボタンスイッチ装置であって、前記アダプターを上向きに付勢する付勢手段を備えたことを特徴とする。   The invention according to claim 2 is the push button switch device according to claim 1, further comprising an urging means for urging the adapter upward.

上記構成によれば、アダプターに付与される上向きの付勢力が増加することになり、アダプターの復帰動作がより迅速になる。   According to the above configuration, the upward urging force applied to the adapter increases, and the return operation of the adapter becomes faster.

また請求項3記載の発明は、請求項1又は2記載の押ボタンスイッチ装置であって、前記スイッチ本体は、さらに、前記スイッチケース内の前記操作体の下方に配設され、前記押ボタン部の押圧に連動した前記操作体の下動により前記スイッチを押圧する押圧体を備え、前記押ボタン部の押圧部位が押ボタン部の隅部の場合に、その隅部に加わる押圧荷重を押圧体の側部の延在方向に均等に分散する一対の分散手段が、前記押圧体の両側部上方にそれぞれ配置されていることを特徴する。   The invention according to claim 3 is the pushbutton switch device according to claim 1 or 2, wherein the switch body is further disposed below the operating body in the switch case, and the pushbutton portion. A pressing body that presses the switch by the downward movement of the operating body in conjunction with the pressing of the push button, and when the pressing portion of the push button portion is a corner portion of the push button portion, the pressing load applied to the corner portion is pressed. A pair of dispersing means for evenly dispersing in the extending direction of the side portions of the pressing member is disposed above both side portions of the pressing body.

ここで、「押圧体」の形状としては、例えばU字状のような枠形状に限らず、枠形状でない平板状のようなものも含まれる。
上記構成によれば、押ボタン部の押圧部位が隅部の場合に、その隅部に加わる押圧荷重を分散手段によって押圧体の側部の延在方向に均等に分散することができる。そのため、隅部を押した場合、隅部のみが大きく沈み込むことはなく、押ボタン部の側部全体が均一に下向きに回転する。この結果、隅部を押した場合のスイッチがオンするストローク(以下、スイッチがオンするストロークをストロークと略称する)は、押ボタン部の側部中央部を押した場合におけるストロークと同様となり、また、隅部を押した場合の操作荷重は、押ボタン部の側部中央部を押した場合における操作荷重と同様となる。そして、上記の作用・効果は、押ボタン部のサイズに影響されないことから、押ボタン部が大型化しても、押圧部位に関係なく操作荷重を均一にでき、且つスイッチがオンするストロークのバラツキを抑えた押ボタンスイッチ装置を実現することができる。このことは、アダプターを用いて押ボタン部をスイッチ本体に対応した大きさよりも大型化するようにした押ボタンスイッチ装置に極めて効果的である。
Here, the shape of the “pressing body” is not limited to a frame shape such as a U shape, but includes a flat plate shape that is not a frame shape.
According to the said structure, when the press site | part of a pushbutton part is a corner part, the press load added to the corner part can be disperse | distributed equally to the extension direction of the side part of a press body by a dispersion | distribution means. Therefore, when the corner portion is pushed, only the corner portion does not sink greatly, and the entire side portion of the push button portion rotates uniformly downward. As a result, the stroke when the switch is turned on when the corner is pressed (hereinafter, the stroke when the switch is turned on is abbreviated as the stroke) is the same as the stroke when the central portion of the side of the push button is pressed. The operation load when the corner is pushed is the same as the operation load when the side central portion of the push button is pushed. And, since the above actions and effects are not affected by the size of the push button part, even if the push button part is enlarged, the operation load can be made uniform regardless of the pressed part, and the variation of the stroke when the switch is turned on is reduced. A suppressed pushbutton switch device can be realized. This is extremely effective for a push button switch device in which the push button portion is made larger than the size corresponding to the switch body using an adapter.

また請求項4記載の発明は、請求項3記載の押ボタンスイッチ装置であって、前記各分散手段は、前記スイッチ本体ケースの外壁のうち前記押圧体の側部に直交する側の外壁に形成されている案内凹部と、前記アダプターの側部に沿って延在し且つ該側部に回転自在に嵌合する基部と、前記案内凹部によって水平方向に摺動自在な案内部とを備えた分散部材と、を含むことを特徴とする。   According to a fourth aspect of the present invention, there is provided the push button switch device according to the third aspect, wherein each of the dispersing means is formed on the outer wall of the switch body case on the side orthogonal to the side of the pressing body. A dispersion provided with a guide recess, a base extending along the side of the adapter and rotatably fitted to the side, and a guide slidable in the horizontal direction by the guide recess And a member.

上記構成により、簡単な構成で分散手段を構成することができる。   With the above configuration, the dispersion unit can be configured with a simple configuration.

また請求項5記載の発明は、請求項4記載の押ボタンスイッチ装置であって、前記押圧体は、両端間の任意の位置を支点として一端側及び他端側が上下に互いに反対方向に揺動し一端側の上動によって前記スイッチ部を押圧することを特徴する。   The invention according to claim 5 is the push button switch device according to claim 4, wherein the pressing body swings up and down in the opposite directions at one end and the other end with an arbitrary position between both ends as a fulcrum. The switch portion is pressed by the upward movement of one end side.

本発明によれば、押ボタンスイッチ装置の厚みを従来例に比べて小さくできる。   According to the present invention, the thickness of the push button switch device can be reduced as compared with the conventional example.

〔本発明の概念〕
先ず、具体的な構成を説明する前に、本発明の概念について、図1〜図5に基づいて、以下に説明する。図1は本発明に係る押ボタンスイッチ装置の正面図であり、図2は本発明に係る押ボタンスイッチ装置の断面図である。
[Concept of the present invention]
First, before describing a specific configuration, the concept of the present invention will be described below with reference to FIGS. FIG. 1 is a front view of a push button switch device according to the present invention, and FIG. 2 is a cross-sectional view of the push button switch device according to the present invention.

本発明に係る押ボタンスイッチ装置1は、スイッチ本体2と、スイッチ本体2の外周に上下動自在に装着されるアダプター3と、アダプター3に装着される押ボタン部72とを含んで構成されている。押ボタン部72は、押圧操作を行う押ボタン本体部72aと、押ボタン本体部72aの下部周縁部に一体的に形成される外向きフランジ部72bとを備えている。スイッチ本体2は押ボタン部72の下方に配設されている。このスイッチ本体2は、スイッチ本体ケース50(後述する図19参照)と、スイッチ本体ケース50内に配設され押ボタン部72の押圧操作、操作解除に連動して上下に移動可能であり且つ上向きに付勢されている操作体70と、スイッチ本体ケース50内に配設され操作体70の下動によりオン又はオフに切り換わるスイッチ部としてのタクトスイッチ58(後述する図19参照)とを備えている。アダプター3は、押ボタン部72が載置される底面部3aと、底面部9の外側周縁部に一体形成され押ボタン部72をガイドするガイド部3bと、底面部9の内側周縁部に一体形成されスイッチ本体2を外装する角筒状部3cとを備えている。そして、上記構成の押ボタンスイッチ装置1が所定の機器等に取り付けられる際には、アダプター3の上面が化粧板Mによって覆われると共に、スイッチ本体ケース50の下部が取付パネルNに取り付けられる。
なお、角筒状部3cは角筒状に限らず、円筒状であってもよい。また、アダプター3のガイド部3bは、押ボタン部72のフランジ部72bを嵌合するように構成されていてもよく、また、ガイド部3bはフランジ部72bを嵌合する構成でなく、押ボタン部72をアダプター3の上に載せておき、押ボタンスイッチ装置1を取付パネルN及び化粧板Mに取り付ける際に、化粧板Mがフランジ部72bの上に載せられることにより押ボタン部72をアダプター3に固定するような構成であってもよい。
A pushbutton switch device 1 according to the present invention includes a switch body 2, an adapter 3 that is mounted on the outer periphery of the switch body 2 so as to be movable up and down, and a pushbutton portion 72 that is mounted on the adapter 3. Yes. The push button portion 72 includes a push button main body portion 72a that performs a pressing operation, and an outward flange portion 72b that is integrally formed on a lower peripheral edge portion of the push button main body portion 72a. The switch body 2 is disposed below the push button portion 72. The switch body 2 is movable up and down in conjunction with a switch body case 50 (see FIG. 19 to be described later) and a push operation of the push button portion 72 disposed in the switch body case 50 and release of the operation. And a tact switch 58 (see FIG. 19 to be described later) as a switch unit that is disposed in the switch body case 50 and is turned on or off by the downward movement of the operation body 70. ing. The adapter 3 is integrated with the bottom surface portion 3 a on which the push button portion 72 is placed, the guide portion 3 b that is integrally formed on the outer peripheral edge portion of the bottom surface portion 9 and guides the push button portion 72, and the inner peripheral edge portion of the bottom surface portion 9. And a rectangular tube-shaped portion 3 c that is formed and covers the switch body 2. And when the pushbutton switch apparatus 1 of the said structure is attached to a predetermined | prescribed apparatus etc., while the upper surface of the adapter 3 is covered with the decorative board M, the lower part of the switch main body case 50 is attached to the attachment panel N.
Note that the rectangular tube-shaped portion 3c is not limited to the rectangular tube shape, and may be a cylindrical shape. Further, the guide portion 3b of the adapter 3 may be configured to fit the flange portion 72b of the push button portion 72, and the guide portion 3b is not configured to fit the flange portion 72b. When the pushbutton switch device 1 is mounted on the mounting panel N and the decorative plate M, the decorative plate M is placed on the flange portion 72b so that the pushbutton portion 72 is mounted on the adapter 3. 3 may be fixed.

次いで、押ボタンスイッチ装置1の動作について説明する。押ボタン部72を押した場合、押ボタン部72の底面が操作体70を押すので、押ボタン部72に連動してアダプター3が下動する。これにより、操作体70が上向きの付勢力に抗して下動し、スイッチ本体2内のスイッチ部(タクトスイッチ58)がオン又はオフに切り換わる。   Next, the operation of the push button switch device 1 will be described. When the push button portion 72 is pushed, the bottom surface of the push button portion 72 pushes the operating body 70, so that the adapter 3 moves down in conjunction with the push button portion 72. As a result, the operating body 70 moves downward against the upward biasing force, and the switch section (tact switch 58) in the switch body 2 is switched on or off.

上記構成の押ボタンスイッチ装置1では、スイッチ本体2の底面から化粧板Mまでの厚みL1は、スイッチ本体2の厚みをL2、スイッチ本体2内のスイッチ部がオン又はオフに切り換わるストローク(以下、単にストロークと略称する)をL3、押ボタン部72のフランジ部72bの肉厚をL4とすると、L1=L2+L3+L4が成立する。
一方、図16及び図17の従来例の押ボタンスイッチ装置では、スイッチ本体2の底面から化粧板Mまでの厚みL1は、図17に示すように、操作体70の肉厚をL5とすると、L1=L2+L3+L4+L5が成立する。そうすると、本発明に係る押ボタンスイッチ装置の方が、操作体70の肉厚L5の分だけ小さい。従って、従来例に比べて薄型化の押ボタンスイッチ装置1を実現できることになる。
In the pushbutton switch device 1 having the above configuration, the thickness L1 from the bottom surface of the switch body 2 to the decorative plate M is the stroke (hereinafter referred to as L2) of the switch body 2 and the switch portion in the switch body 2 is turned on or off. L1 = L2 + L3 + L4 is established, where L3 is simply referred to as a stroke) and L4 is the thickness of the flange portion 72b of the push button portion 72.
On the other hand, in the pushbutton switch device of the conventional example of FIGS. 16 and 17, when the thickness L1 from the bottom surface of the switch body 2 to the decorative board M is as shown in FIG. L1 = L2 + L3 + L4 + L5 is established. Then, the push button switch device according to the present invention is smaller by the thickness L5 of the operating body 70. Therefore, it is possible to realize the push button switch device 1 that is thinner than the conventional example.

(1)上記の例では、操作体70の上端はスイッチ本体2よりも上方に突出していたけれども、図3に示すように、操作体70の上端がスイッチ本体2内にあって、且つ押ボタン部72の底部が下方に突出した突出部72cを有し、この突出部72cが操作体70の上端に当接した構成であってもよい。   (1) In the above example, the upper end of the operating body 70 protrudes upward from the switch body 2, but the upper end of the operating body 70 is within the switch body 2 and is a push button as shown in FIG. The bottom portion of the portion 72 may have a protruding portion 72 c that protrudes downward, and the protruding portion 72 c may be in contact with the upper end of the operating body 70.

(2)上記の例では、押ボタン部72の底面が操作体70を押すように構成されていたが、図4に示すようにアダプター3が操作体70を直接押す構成であってもよい。   (2) In the above example, the bottom surface of the push button portion 72 is configured to press the operating body 70, but the adapter 3 may be configured to directly press the operating body 70 as shown in FIG.

(3)上記の例では、押ボタン部72はフランジ部72bを備えていたが、図5に示すようにフランジ部72bのない構成であってもよい。なお、この場合、ガイド部3bの高さがフランジ部72bの肉厚L4に相当するので、フランジ部72bのない構成であっても、上記のL1=L2+L3+L4が成立する。   (3) In the above example, the push button portion 72 includes the flange portion 72b. However, as shown in FIG. 5, a configuration without the flange portion 72b may be used. In this case, since the height of the guide portion 3b corresponds to the thickness L4 of the flange portion 72b, the above-described L1 = L2 + L3 + L4 is established even in the configuration without the flange portion 72b.

押ボタン部72は、透光性を有する樹脂等から成り平面視ほぼ正方形状に形成されている。この押ボタン部72は、アダプター3よりも上方に突出した押ボタン本体部72aと、押ボタン本体部72aの下部周縁部に一体的に形成される外向きフランジ部72bとを備える。外向きフランジ部72bの外周面には、周方向に延在する切欠部72b1(図11参照)が形成されている。   The push button portion 72 is made of a translucent resin or the like and is formed in a substantially square shape in plan view. The push button portion 72 includes a push button main body portion 72a that protrudes upward from the adapter 3 and an outward flange portion 72b that is integrally formed on the lower peripheral edge portion of the push button main body portion 72a. A cutout portion 72b1 (see FIG. 11) extending in the circumferential direction is formed on the outer peripheral surface of the outward flange portion 72b.

スイッチ本体2は押ボタン部72の下方に配設されている。このスイッチ本体2は、スイッチ本体ケース50と、スイッチ本体ケース50内に配設され押ボタン部72の押圧操作、操作解除に連動して上下に移動可能であり且つ上向きに付勢されている操作体70と、スイッチ本体ケース50内に配設され操作体70の下動によりオン又はオフに切り換わるスイッチ部としてのタクトスイッチ58とを備えている。なお、スイッチ本体2の詳細な構成は、後述する。   The switch body 2 is disposed below the push button portion 72. The switch main body 2 is arranged in the switch main body case 50 and is operated in an upwardly biased manner in association with a pressing operation and a release operation of the push button portion 72 provided in the switch main body case 50. A body 70 and a tact switch 58 serving as a switch unit that is disposed in the switch body case 50 and is turned on or off by the downward movement of the operation body 70 are provided. The detailed configuration of the switch body 2 will be described later.

アダプター3は、ほぼ正方形の枠状を成し、中央部に操作体70が配置されている。このアダプター3は、押ボタン部72が載置される底面部3aと、底面部3aの外側周縁部に一体的に形成され押ボタン部72のフランジ部72bが嵌合するガイド部3bと、底面部3aの内側周縁部に一体的に形成されスイッチ本体2を外装する角筒状部3cとを備えている。ガイド部3bは底面部3aの外側周縁部から上方に延びて形成され、角筒状部3cは底面部3aの内側周縁部から下方に延びて形成されている。ガイド部3bの内周面における上端部側には、爪部3b1(図11参照)が周方向に複数個形成されている。この爪部3b1がフランジ部72bの切欠部72b1(図11参照)と係合することで、押ボタン部72がアダプター3に着脱自在に装着され、操作体70に付与されている上向きの付勢力によって押ボタン部72がアダプター3から外れることが防止されている。   The adapter 3 has a substantially square frame shape, and an operation body 70 is disposed at the center.

In relation to the dispersion member 30a, guide recesses 34a are formed in the front and rear outer walls of the switch body case 50, respectively, and in relation to the dispersion member 30b, the front and rear outer walls of the switch body case 50 are guided. Recesses 34b are respectively formed. The height position of the guide recess 34a and the height position of the guide recess 34b are substantially the same. The dispersion member 30a is formed in a substantially U-shape, extends along the outer surface of the left side of the operation body 8, and is inserted into the guide recess 34a and a base 31a that is rotatably fitted in the fitting recess 40a. And a connecting portion 32a for connecting the base portion 31a and the guiding portion 33a. The dispersion member 30b has the same configuration as the dispersion member 30a.

また、スイッチ本体2内には後述するように発光ダイオード(以下、LEDと称する)、が実装されており、このLEDの光が記名板20を介して押ボタン部72を照射するようになっている。   In addition, a light emitting diode (hereinafter referred to as LED) is mounted in the switch body 2 as will be described later, and the light from the LED irradiates the push button portion 72 via the name plate 20. Yes.

また、左右一対の付勢手段22a,22bは、上方に開口した有底筒状体23a,23bと、有底筒状体23a,23bに内装されるコイルバネ24a,24bとから構成される。有底筒状体23aは、アダプター3の左辺部下部に形成されている凹部25a(図17参照)に嵌り込んでおり、有底筒状体23bは、アダプター3の右辺部下部に形成されている凹部25b(図17参照)に嵌り込んでいる。なお、有底筒状体23aはその底面が取付パネルNに載置される。この付勢手段22a,22bによって、アダプター3への上向きの付勢力が付与される。これにより、操作体70から押ボタン部72を介して付与されるアダプター3の上向きの付勢力に、付勢手段22a,22bの上向きの付勢力も加わるので、アダプター3の復帰動作がより迅速になる。   The pair of left and right urging means 22a and 22b includes a bottomed cylindrical body 23a and 23b opened upward, and coil springs 24a and 24b provided in the bottomed cylindrical bodies 23a and 23b.

An upward urging force is applied to the adapter 3 by the urging means 22a and 22b. As a result, the upward biasing force of the biasing means 22a, 22b is also applied to the upward biasing force of the adapter 3 applied from the operating body 70 via the push button portion 72, so that the return operation of the adapter 3 is performed more quickly. Become.

次いで、図18及び図19を参照して、スイッチ本体2の構造を詳述する。図18はスイッチ本体2を上方から見た分解斜視図、図19はスイッチ本体2を下方から見た分解斜視図である。
スイッチ本体2は、樹脂製スイッチ本体ケース50を備えており、スイッチ本体ケース50は、矩形の枠体50aと、該枠体50aの上面前寄りの位置に枠体50a内を前後に仕切るべく一定形成された枠体50aの高さのほぼ半分程度の高さを有する仕切板50bと、該仕切板50bによる前端部の空間の上面を閉塞する第1の閉塞板50cと、仕切板50bによる前側を除く中央前寄りから後端にかけての空間の下面を閉塞する第2の閉塞板50dとを備えている。
Next, the structure of the switch body 2 will be described in detail with reference to FIGS. 18 and 19. 18 is an exploded perspective view of the switch body 2 as viewed from above, and FIG. 19 is an exploded perspective view of the switch body 2 as viewed from below.
The switch body 2 includes a resin switch body case 50. The switch body case 50 is fixed to partition the frame body 50a forward and backward at a rectangular frame body 50a and a position in front of the upper surface of the frame body 50a. A partition plate 50b having a height approximately half the height of the formed frame 50a, a first closing plate 50c for closing the upper surface of the space at the front end portion by the partition plate 50b, and a front side by the partition plate 50b And a second closing plate 50d that closes the lower surface of the space from the center front side to the rear end except for.

そして、枠体50aと仕切板50bと第1の閉塞板50cとにより、枠体50a内の前端部に形成された平面視横長の長方形状を成す空間が、後述するプリント基板の配置スペース52aとして使用され、枠体50aと仕切板50bと第2の閉塞板50dとにより、枠体50a内の中央前寄りから後端にかけて形成された平面視ほぼ正方形状を成す空間が、後述する押ボタン部の上下への可動スペース52bとして使用される。   Then, a space formed in a horizontally long rectangular shape in a plan view formed at the front end portion in the frame 50a by the frame 50a, the partition plate 50b, and the first closing plate 50c serves as an arrangement space 52a for a printed circuit board to be described later. A space that is used and has a substantially square shape in plan view formed by the frame body 50a, the partition plate 50b, and the second closing plate 50d from the center front side to the rear end in the frame body 50a. Is used as a movable space 52b up and down.

まず、枠体50a内の前端部に形成された配置スペース52aには、後述する発光素子の点灯制御用の半導体集積回路54をはじめ各種の回路素子が実装されたプリント基板56が配設され、このプリント基板56のほぼ中央部にはタクトスイッチ58が実装されている。なお、プリント基板56はその裏面が第1の閉塞板50cの下面に対向して配設されており、配設状態のプリント基板56の下面側にタクトスイッチ58が位置し、この状態でタクトスイッチ58が、スイッチ固有の所定値以上の操作力によって上向きに押圧されることにより、タクトスイッチ58がオンするようになっている。   First, in the arrangement space 52a formed at the front end portion in the frame 50a, a printed circuit board 56 on which various circuit elements are mounted, including a semiconductor integrated circuit 54 for controlling the lighting of the light emitting elements described later, is disposed. A tact switch 58 is mounted almost at the center of the printed circuit board 56. The back surface of the printed circuit board 56 is disposed to face the lower surface of the first closing plate 50c, and a tact switch 58 is located on the lower surface side of the printed circuit board 56 in the disposed state. The tact switch 58 is turned on when the switch 58 is pressed upward by an operation force equal to or greater than a predetermined value unique to the switch.

また、配設状態のプリント基板56の下面後端部には、発光素子である4個(但し、個数は4個に限るものではない)の発光ダイオード(以下、LEDと称する)60が配列状態で実装され、アクリルなどの透明材料からなる導光部材62によりこれらのLED60の光が、記名板20を介して押ボタン部72まで導光されるようになっている。   Further, four light emitting diodes (hereinafter referred to as “LEDs”) 60 as light emitting elements are arranged at the rear end of the lower surface of the printed circuit board 56 in the arrangement state. The light of these LEDs 60 is guided to the push button part 72 via the name plate 20 by the light guide member 62 made of a transparent material such as acrylic.

このとき、特に図13に示されるように、導光部材62は、可動スペース52bの左右幅よりも幅の狭い平板状基部62aと、該基部62aの前端に形成された段差部62bとから成り、基部62aの前端面には各LED60がそれぞれ近接して配置されている。そして、基部62aが配置スペース52a側から仕切板50bの下側を経て第2の閉塞板50dに沿って可動スペース52b内に導入され、導光部材62が枠体50a内に配設されている。   At this time, as particularly shown in FIG. 13, the light guide member 62 includes a flat plate-like base portion 62a having a width smaller than the left and right width of the movable space 52b, and a stepped portion 62b formed at the front end of the base portion 62a. The LEDs 60 are arranged close to each other on the front end surface of the base 62a. Then, the base 62a is introduced from the arrangement space 52a side to the movable space 52b along the second closing plate 50d through the lower side of the partition plate 50b, and the light guide member 62 is arranged in the frame 50a. .

各LED60の発する光は、基部62aの前端面から内部に進入すると、基部62aの面方向に各LED60の光が拡散し、その上方に配設される押ボタン部72が下方から照光されて押ボタン部72の押圧によるタクトスイッチ58のオン状態が表示、報知されるようになっている。なお、各LED60による押ボタン部72の照光効果を上げるため、導光部材62の下面に沿って白色の反射シート64が配設されている。   When the light emitted from each LED 60 enters the inside from the front end surface of the base portion 62a, the light from each LED 60 diffuses in the surface direction of the base portion 62a, and the push button portion 72 disposed above the light is illuminated from below and pushed. The on state of the tact switch 58 due to the pressing of the button part 72 is displayed and notified. Note that a white reflective sheet 64 is disposed along the lower surface of the light guide member 62 in order to increase the illumination effect of the push button portion 72 by each LED 60.

ところで、プリント基板56に実装状態におけるタクトスイッチ58には、該タクトスイッチ58を下方から覆うように平面視四角形の可撓性ラバー体66が装着されており、このラバー体66の復元力とタクトスイッチ58の操作力とを合わせた下向きの力が、後述する押圧体84を介して押ボタン部72に対して上向きの付勢力として作用する。すなわち、ラバー体66とタクトスイッチ58が、押圧体84の付勢手段として機能する。よって、押ボタン部72を付勢するためのばね等の付勢手段を別途設ける必要がなく、部品点数の低減を図ることができる。   Incidentally, the tact switch 58 mounted on the printed circuit board 56 is provided with a flexible rubber body 66 having a rectangular shape in plan view so as to cover the tact switch 58 from below. A downward force combined with the operation force of the switch 58 acts as an upward biasing force on the push button portion 72 via a pressing body 84 described later. That is, the rubber body 66 and the tact switch 58 function as an urging means for the pressing body 84. Therefore, it is not necessary to separately provide a biasing means such as a spring for biasing the push button portion 72, and the number of parts can be reduced.

つぎに、枠体50a内の中央前寄りから後端にかけて形成された可動スペース52bには、ほぼ正方形の枠状を成す操作体70が上下に移動自在に配設されている。   Next, in a movable space 52b formed from the center front side to the rear end in the frame body 50a, an operation body 70 having a substantially square frame shape is arranged to be movable up and down.

ここで、操作体70は、上方に向けて拡開した枠状部70aを有している。また、操作体70の枠状部70aの左辺の外側下面及び右辺の外側下面の各前後端部には、合計4個の係合凹部78が切り欠き形成され、枠体50aの可動スペース52bの内周の前後に各係合凹部78に対応して下向きの係合爪80が形成されており、操作体70の前後を片方ずつ撓ませながら可動スペース52b内に操作体70を挿入していくと、各係合凹部78に各係合爪80が係合し、操作体70が上方に抜けない状態で可動スペース52b内に上下動自在に配設される。   Here, the operating body 70 has a frame-shaped portion 70a that expands upward. In addition, a total of four engagement recesses 78 are formed in the front and rear end portions of the outer lower surface on the left side and the outer lower surface on the right side of the frame-shaped portion 70a of the operation body 70, so that the movable space 52b of the frame body 50a is formed. Downward engaging claws 80 are formed on the front and rear of the inner periphery corresponding to the respective engaging recesses 78, and the operating body 70 is inserted into the movable space 52b while bending the front and rear of the operating body 70 one by one. Then, each engagement claw 80 is engaged with each engagement recess 78, and the operation body 70 is disposed in the movable space 52b so as to be movable up and down in a state where it does not come out upward.

このとき、上記したように、後述する押圧体84を介してラバー体66の復元力とタクトスイッチ58の操作力とを合わせた下向きの力が押ボタン部72及び操作体70に上向きの付勢力として加わるため、操作体70に装着された押ボタン部72をこの付勢力に抗して下向きに押圧操作すると、操作体70が押ボタン部72の押圧に連動し、各係合爪80のうち押ボタン部72及び操作体70の押圧部位に応じた係合凹部78及びこれに係合した係合爪80を回転中心として操作体72の押圧部位が下向きに回転する。   At this time, as described above, the downward force obtained by combining the restoring force of the rubber body 66 and the operating force of the tact switch 58 is applied to the push button portion 72 and the operating body 70 via the pressing body 84 described later. Therefore, when the push button portion 72 attached to the operation body 70 is pressed downward against this biasing force, the operation body 70 is interlocked with the push of the push button portion 72 and The pressing portion of the operating body 72 rotates downward with the engaging recess 78 corresponding to the pressing portion of the push button portion 72 and the operating body 70 and the engaging claw 80 engaged therewith as the rotation center.

例えば、押ボタン部72の右前端部を押圧すると、左後側の係合凹部78とこれに係合した係合爪80が回転中心となり、押ボタン部72の左後端部を押圧すると、右前側の係合凹部78とこれに係合した係合爪80が回転中心となり、押ボタン部72の左端中央部を押圧すると、右側の両係合凹部78とこれらに係合した両係合爪80が回転中心となり、押ボタン部72の右端中央部を押圧すると、左側の両係合凹部78とこれらに係合した両係合爪80が回転中心となり、押ボタン部72を介した操作体70の押圧部位に応じて、操作体70の回転中心が切り換わる。   For example, when the right front end portion of the push button portion 72 is pressed, the engagement recess 78 on the left rear side and the engagement claw 80 engaged therewith become the rotation center, and when the left rear end portion of the push button portion 72 is pressed, When the engagement recess 78 on the right front side and the engagement claw 80 engaged therewith become the center of rotation and the center of the left end of the push button portion 72 is pressed, both engagement recesses 78 on the right side and both engagements engaged with these When the claw 80 becomes the center of rotation and the center of the right end of the push button portion 72 is pressed, the left engaging recesses 78 and the both engaging claws 80 engaged therewith become the center of rotation, and the operation via the push button portion 72 is performed. The rotation center of the operating body 70 is switched according to the pressed part of the body 70.

図18、図19に示すように、平面視コ字状の金属性の押圧体84が、可動スペース52b内の操作体70の下方に配設されており、押圧体84の左右の両脚部84a,84bは、操作体70の左、右辺下方のほぼ中央部から前端にわたって位置すると共に、押圧体84の両脚部84a,84bを連結する連結部84cは、配置スペース52a内に導入され、連結部84cの中央部84c1がラバー体66の中央の突部下面に当接している。   As shown in FIGS. 18 and 19, a metallic pressing body 84 having a U-shape in plan view is disposed below the operation body 70 in the movable space 52 b, and both left and right leg portions 84 a of the pressing body 84. , 84b are located from the substantially central portion below the left and right sides of the operating body 70 to the front end, and a connecting portion 84c for connecting both the leg portions 84a, 84b of the pressing body 84 is introduced into the arrangement space 52a. A central portion 84c1 of 84c is in contact with the lower surface of the protruding portion at the center of the rubber body 66.

また、押圧体84の両脚部84a,84bの外側ほぼ中央に突出して当接片86a,86bがそれぞれ一体形成され、両当接片86a,86bの下方位置におけるスイッチ本体ケース50の枠体50a上面それぞれには、押圧体84を支える支点となる突部を成す段部88が上方に盛り上がって一体形成され、操作体70の左右両辺の下面ほぼ中央部にそれぞれ下向きに突設された当接部90が押圧体84の両脚部84a,84bの後端部上面に当接している。   Further, the contact pieces 86a and 86b are integrally formed so as to protrude substantially from the outer sides of both the leg portions 84a and 84b of the pressing body 84, and the upper surface of the frame body 50a of the switch body case 50 at a position below the both contact pieces 86a and 86b. In each of them, a stepped portion 88 that forms a protrusion serving as a fulcrum that supports the pressing body 84 is formed upward and integrally formed, and abutting portions that protrude downward at substantially the center of the lower surfaces of the left and right sides of the operating body 70. 90 is in contact with the upper surfaces of the rear end portions of the leg portions 84a and 84b of the pressing body 84.

さらに、押圧体84は、左右の段部88に当接する両当接片86a,86bを支点とし、左右の当接部90に当接する押圧体84の両脚部84a,84bの後端部を力点とし、ラバー体66に当接する連結部84cの中央部84c1を作用点とする「てこ」として機能し、押ボタン部72の押圧により、その押圧部位に応じた操作体70の部位が下向きに回転すると、操作体70の両当接部90により押圧体84の両脚部84a,84bの後端部が下向きの押し下げられ、これにより支点となる両当接片86a,86bを挟んで力点の反対側に位置する中央部84c1が上向きに押し上げられてラバー体66を介してタクトスイッチ58がこれらの復元力及び操作力に抗して押圧され、タクトスイッチ58がオンするようになっている。ここでは、左右の段部88に押圧体84の両当接片86a,86bが当接して支点とするようにしているが、当接片86a,86bがなく直接押圧体84の両脚部84a,84bの中央部下面に当接するようにしてもよい。   Further, the pressing body 84 has both contact pieces 86a and 86b contacting the left and right step portions 88 as fulcrums, and the rear end portions of both legs 84a and 84b of the pressing body 84 contacting the left and right contact portions 90 are power points. And function as a “lever” with the central portion 84c1 of the connecting portion 84c in contact with the rubber body 66 as an action point, and the portion of the operating body 70 corresponding to the pressed portion rotates downward by the pressing of the push button portion 72. Then, the rear end portions of the leg portions 84a and 84b of the pressing body 84 are pushed downward by the both abutting portions 90 of the operating body 70, thereby sandwiching the abutting pieces 86a and 86b serving as fulcrums, opposite to the force point. The central portion 84c1 positioned at the position is pushed upward, the tact switch 58 is pressed against the restoring force and the operating force via the rubber body 66, and the tact switch 58 is turned on. Here, both contact pieces 86a and 86b of the pressing body 84 are in contact with the left and right step portions 88 as fulcrums, but there are no contact pieces 86a and 86b, and both leg portions 84a and 86b of the pressing body 84 are directly provided. You may make it contact | abut to the center part lower surface of 84b.

なお、押圧体84の力点の位置は、押ボタン部72及び操作体70の中心と平面視でほぼ同列上に並ぶように設定されており、これにより押ボタン部72の押圧部位がどこであっても、押圧体84の力点に加わる操作荷重をほぼ均一にしている。   In addition, the position of the force point of the pressing body 84 is set so as to be aligned substantially in the same row in plan view with the center of the push button portion 72 and the operation body 70, so that where the pressing portion of the push button portion 72 is located. Also, the operation load applied to the power point of the pressing body 84 is made substantially uniform.

そして、押圧体84の支点の位置、つまり左右の段部88が押圧体84に当接する位置を力点側又は作用点側に変更すれば、押圧体84の力点に加わる操作荷重を任意に可変設定することができる。すなわち、作用点側に加わるべきタクトスイッチ58の操作力とラバー体66の復元力との合力は一定であるため、例えば支点を力点側に寄せれば、タクトスイッチ58の操作力とラバー体66の復元力との合力に打ち勝つだけの操作荷重としてより大きな荷重が必要になり、逆に支点を作用点側に寄せれば、タクトスイッチ58の操作力とラバー体66の復元力との合力に打ち勝つだけの操作荷重はより小さくて済む。   If the position of the fulcrum of the pressing body 84, that is, the position where the left and right step portions 88 abut against the pressing body 84 is changed to the power point side or the action point side, the operation load applied to the force point of the pressing body 84 can be arbitrarily variably set. can do. That is, since the resultant force of the operating force of the tact switch 58 to be applied to the action point side and the restoring force of the rubber body 66 is constant, for example, if the fulcrum is brought closer to the power point side, the operating force of the tact switch 58 and the rubber body 66 Therefore, a larger load is required as an operation load that only overcomes the resultant force of the restoring force, and conversely, if the fulcrum is moved closer to the point of action, the resultant force of the operating force of the tact switch 58 and the restoring force of the rubber body 66 The operating load that only overcomes is smaller.

ところで、特に図19に示されるように、スイッチ本体ケース50の下面側の第2の閉塞板50dには、左右の両端部から外側に張り出して前後方向に延びる突条体92が形成され、これらの突条体92と枠体50aの左右の両辺との間に前後方向のガイド路が形成されている。   By the way, as shown in FIG. 19 in particular, the second closing plate 50d on the lower surface side of the switch body case 50 is formed with protrusions 92 extending outward from the left and right ends and extending in the front-rear direction. A guide path in the front-rear direction is formed between the protrusion 92 and the left and right sides of the frame 50a.

そして、図10、図11に示すように、スイッチ本体ケース50の下面側には該下面を覆う裏面カバー94が設けられ、前記ガイド路をスライド自在に移動する内向きの鉤状係合体96が裏面カバー94の左端前後及び右端前後にそれぞれ一体形成され、これにより裏面カバー94がスイッチ本体ケース50の下面を覆って着脱自在に装着されている。   As shown in FIGS. 10 and 11, a back cover 94 is provided on the lower surface side of the switch body case 50 to cover the lower surface, and an inward hook-shaped engagement body 96 that moves slidably along the guide path is provided. The back cover 94 is integrally formed on the left and right ends and on the right end, respectively, so that the back cover 94 covers the lower surface of the switch body case 50 and is detachably mounted.

この裏面カバー94の後端部上面には、図18に示すように矩形凹部98とその矩形凹部98の左右方向中央部に係止部99が形成され、付勢体としての線状ばね100が、係止部99により前後に移動可能に矩形凹部98に収容されている。また、第2の閉塞板50dの後端部下面には、図19に示すように左右一対の係合突起102が下向きに突出して一体形成され、この係合突起102に線状ばね100の両端部が前側から当接し、これにより裏面カバー94が線状ばね100によって前方向に付勢された状態でスイッチ本体ケース50の下面側にスライド自在に装着されている。なお、線状ばね100による前方への付勢力が加わっていない状態において、裏面カバー94がスイッチ本体ケース50から脱離せず、かつ、裏面カバー94を容易にスライドさせ得るように、特に後側左右の鉤状係合体96と枠体50aには凹凸の組み合わせによる係止構造が採用されている。   On the upper surface of the rear end portion of the back cover 94, as shown in FIG. 18, a rectangular recess 98 and a locking portion 99 are formed at the center in the left-right direction of the rectangular recess 98, and a linear spring 100 as an urging body is provided. , And is accommodated in the rectangular recess 98 so as to be movable forward and backward by the locking portion 99. Further, as shown in FIG. 19, a pair of left and right engaging projections 102 project downward and are integrally formed on the lower surface of the rear end portion of the second closing plate 50d, and both ends of the linear spring 100 are formed on the engaging projection 102. The part abuts from the front side, whereby the back cover 94 is slidably mounted on the lower surface side of the switch body case 50 in a state where the back cover 94 is urged forward by the linear spring 100. It should be noted that, particularly in the state where the forward biasing force by the linear spring 100 is not applied, the rear side cover 94 is not detached from the switch body case 50 and the rear side cover 94 can be easily slid. The hook-like engagement body 96 and the frame body 50a are provided with a locking structure using a combination of irregularities.

さらに、裏面カバー94の下面前端には前向き横長のスイッチ取付保持用の第1フック体106が一体形成され、スイッチ本体ケース50の枠体50aの下面後端には後向き横長のスイッチ取付保持用の第2フック体108が一体形成されている。   Further, a first hook body 106 for holding a horizontally long switch mounted forward is integrally formed at the front end of the bottom surface of the back cover 94, and a switch for holding a horizontally long switch facing backward is formed at the rear bottom end of the frame body 50 a of the switch body case 50. The second hook body 108 is integrally formed.

そして、組み上がった押ボタンスイッチ装置は、取付パネルN及び化粧板Mに取り付けられる。取付パネルNに取り付ける場合には、取付パネルNにスイッチ本体ケース50とほぼ同形状の矩形の取付孔112を穿設し、図10及び図12に示すように、取付孔112に第1フック体106を係止し、この状態でスイッチカバー50を前方へ引っ張れば、線状ばね100の付勢力に抗して裏面カバー94がスイッチ本体ケース50に対して後方へスライドすることになり、両フック体106,108間の距離が縮まり、第2フック体108を取付孔112も係止することが可能になる。   Then, the assembled push button switch device is attached to the attachment panel N and the decorative board M. When mounting to the mounting panel N, a rectangular mounting hole 112 having substantially the same shape as the switch body case 50 is formed in the mounting panel N, and the first hook body is formed in the mounting hole 112 as shown in FIGS. If the switch cover 50 is pulled forward in this state, the back cover 94 slides backward with respect to the switch body case 50 against the urging force of the linear spring 100, and both hooks The distance between the bodies 106 and 108 is shortened, and the second hook body 108 can be locked in the mounting hole 112 as well.

その後、スイッチカバー50の前方への引っ張りを解除すれば、線状ばね100の付勢力により裏面カバー94がスイッチ本体ケース50に対して前方へスライドしてもとの状態に戻り、押ボタンスイッチ装置が取付パネルNの取付孔112に取り付けられるのである。   Thereafter, when the forward pulling of the switch cover 50 is released, the back cover 94 returns to the original state by sliding forward with respect to the switch body case 50 by the urging force of the linear spring 100, and the push button switch device. Is attached to the attachment hole 112 of the attachment panel N.

<中央押しの動作>
つぎに、押ボタン部72の押圧操作による押ボタンスイッチ装置の具体的動作について詳述するが、押ボタン部72の押圧に操作体70が連動するため、以下の動作等の説明では、押ボタン部72の押圧部位を操作体70の押圧部位と同一に扱って説明することとする。
<Center press action>
Next, the specific operation of the push button switch device by the pressing operation of the push button portion 72 will be described in detail. Since the operating body 70 is interlocked with the pressing of the push button portion 72, the following description of the operation and the like will be given below. The pressing part of the part 72 will be described in the same manner as the pressing part of the operating body 70.

上記の構成を有する押ボタンスイッチ装置が、機器起動用スイッチなどに適用され、使用者が押ボタン部72を押圧操作した場合には、操作体70がタクトスイッチ58の操作力及びラバー体66の復元力による付勢力に抗して押圧され、操作体70の両当接部90が押圧体84の脚部84a,84bの後端部を押し下げるため、左右の段部88に当接する両当接片86a,86bを支点として押圧体84の連結部84cが押し上げられ、これによりラバー体66を介してタクトスイッチ58がこれらの復元力や操作力に抗して押圧されてオンする。   When the push button switch device having the above configuration is applied to a device activation switch or the like, and the user presses the push button portion 72, the operation body 70 operates the tact switch 58 and the rubber body 66. Both abutting portions 90 are pressed against the urging force due to the restoring force, and the both abutting portions 90 of the operating body 70 push down the rear end portions of the leg portions 84a and 84b of the pressing body 84. The connecting portion 84c of the pressing body 84 is pushed up with the pieces 86a and 86b as fulcrums, whereby the tact switch 58 is pressed against the restoring force and the operating force via the rubber body 66 and is turned on.

このとき、タクトスイッチ58のオンにより各LED60が点灯して導光部材62により各LED60の光が押ボタン部72まで導光され、各LED60の点灯状態が所定条件の成立(スイッチ操作後、機器が所定状態になるなど)まで保持され、押ボタン部72が照光されてタクトスイッチ58がオン状態になったことが使用者に目視できるようになっている。   At this time, each LED 60 is turned on when the tact switch 58 is turned on, and the light of each LED 60 is guided to the push button portion 72 by the light guide member 62, and the lighting state of each LED 60 satisfies the predetermined condition (after the switch operation, the device Until the push button 72 is illuminated and the tact switch 58 is turned on.

いま、図8中に示す押ボタン部72の中央であるB部分が押圧されると、押ボタン部72への押圧力が操作体70のほぼ中央部に加わる。このとき、操作体70は、各係合爪80の各係合凹部78との係合箇所のいずれをも支点とすることがなく、操作体70はラバー体66の復元力及びタクトスイッチ58の操作力による上向きの付勢力に抗して下方に平行移動し、押ボタン部72への押圧力が操作体70の中央付近に位置する両当接部90にそのまま伝わる。なお、このとき、分散部材30a,30bは、図20に示すように共にその案内部33a,33bが水平方向に摺動し、基部31a,31bが操作体70と共に下動する。そのため、操作体70は、左右前後方向にぶれることなく円滑に平行移動する。また、このとき、押圧時に両当接部90を介して操作体70が受ける反力は、押圧体84を介して受けるラバー体66の復元力とタクトスイッチ58の操作力とを合わせた力であり、これが操作荷重に相当する。   Now, when the portion B which is the center of the push button portion 72 shown in FIG. 8 is pressed, the pressing force to the push button portion 72 is applied to the substantially central portion of the operating body 70. At this time, the operation body 70 does not use any of the engagement portions of the engagement claws 80 with the respective engagement recesses 78 as fulcrums, and the operation body 70 has the restoring force of the rubber body 66 and the tact switch 58. Parallel to the downward direction against the upward biasing force by the operating force, the pressing force to the push button portion 72 is transmitted as it is to both contact portions 90 located near the center of the operating body 70. At this time, as shown in FIG. 20, the guide portions 33 a and 33 b of the dispersion members 30 a and 30 b slide in the horizontal direction, and the base portions 31 a and 31 b move down together with the operating body 70. Therefore, the operating body 70 moves smoothly in parallel without being shaken in the left-right front-rear direction. At this time, the reaction force received by the operating body 70 via both contact portions 90 at the time of pressing is a force obtained by combining the restoring force of the rubber body 66 received via the pressing body 84 and the operating force of the tact switch 58. Yes, this corresponds to the operating load.

その結果、操作体70の両当接部90により押圧体84の後端部が押し下げられ、上記したように、左右の段部88に当接する両当接片86a,86bを支点として押圧体84の連結部84cが押し上げられ、これによりタクトスイッチ58が押圧されてオンする。   As a result, the rear end portion of the pressing body 84 is pushed down by the both contact portions 90 of the operating body 70, and as described above, the pressing body 84 with both contact pieces 86a and 86b contacting the left and right step portions 88 as fulcrums. The connecting portion 84c is pushed up, whereby the tact switch 58 is pressed and turned on.

<仮想端押しの動作>
ここで、仮想端押しの動作とは、押ボタン部72の実際の端押しの動作ではなく、押圧体70の正方形状を基準として設定した押圧部位における押しの動作を意味する。
図8中に示す押ボタン部72の中央B部分の左側のA部分が押圧されると、押ボタン部72への押圧力が操作体70の左端部寄りに加わるため、押圧体84の脚部84aを介して操作体70の左端部に加わる付勢力に抗して、操作体70の左端部が右側の両係合爪80と両係合凹部78との係合箇所P1,P2を回転中心として下向きに回転し、操作体70の左端部が下動する。なお、このとき、分散部材30aは、図20に示すように、その案内部33aが水平方向に摺動し、基部31aが操作体70と共に係合箇所P1,P2を回転中心として下向きに回転しつつ下動する。
<Virtual end pushing operation>
Here, the virtual end pushing operation means not the actual end pushing operation of the push button portion 72 but the pushing operation at the pressing portion set based on the square shape of the pressing body 70.
When the A portion on the left side of the central B portion of the push button portion 72 shown in FIG. 8 is pressed, the pressing force applied to the push button portion 72 is applied closer to the left end portion of the operating body 70, so The left end portion of the operating body 70 rotates about the engagement points P1, P2 between the right engaging claws 80 and the engaging recesses 78 against the urging force applied to the left end portion of the operating body 70 via 84a. And the left end portion of the operation body 70 moves downward. At this time, as shown in FIG. 20, in the dispersing member 30a, the guide portion 33a slides in the horizontal direction, and the base portion 31a rotates downward together with the operating body 70 around the engagement points P1 and P2. While moving down.

そして、操作体70の左端部の下動により、操作体70の特に左側の当接部90が押圧体84の脚部84aを強く押下するが、押圧体84自体がある程度剛性を有するため、脚部84aの押下であっても押圧体84の脚部84bも同様に押下されることになる。   Then, due to the downward movement of the left end portion of the operating body 70, the contact portion 90 on the left side of the operating body 70 strongly presses down the leg portion 84a of the pressing body 84, but the pressing body 84 itself has a certain degree of rigidity. Even when the portion 84a is pressed, the leg portion 84b of the pressing body 84 is also pressed in the same manner.

その結果、押ボタン部72の中央B部分を押圧したのと同じように、左右の段部88に当接する両当接片86a,86bを支点として押圧体84の連結部84cが押し上げられ、これによりラバー体66を介してタクトスイッチ58がこれらの復元力や操作力に抗して押圧されてオンする。   As a result, the connecting portion 84c of the pressing body 84 is pushed up with the two abutting pieces 86a and 86b abutting on the left and right step portions 88 as fulcrums in the same manner as when the center B portion of the push button portion 72 is pressed. Thus, the tact switch 58 is pressed against the restoring force and the operating force through the rubber body 66 and is turned on.

一方、図8中に示す押ボタン72の中央B部分の右側のC部分が押圧されると、押ボタン部72への押圧力が操作体70の右端部寄りに加わるため、押圧体84の脚部84bを介して操作体70の右端部に加わる付勢力に抗して、操作体70の右端部が左側の両係合爪80と両係合凹部78との係合箇所P3,P4を回転中心として下向きに回転し、操作体70の右端部が下動する。なお、このとき、分散部材30bは、その案内部33bが水平方向に摺動し、基部31bが操作体70と共に係合箇所P3,P4を回転中心として下向きに回転しつつ下動する。   On the other hand, when the C portion on the right side of the central B portion of the push button 72 shown in FIG. 8 is pressed, the pressing force on the push button portion 72 is applied closer to the right end portion of the operating body 70, so The right end of the operating body 70 rotates the engagement points P3 and P4 between the left engaging claws 80 and the engaging recesses 78 against the urging force applied to the right end of the operating body 70 via the portion 84b. It rotates downward as the center, and the right end portion of the operation body 70 moves downward. At this time, the dispersing member 30b moves downward while the guide portion 33b slides in the horizontal direction, and the base portion 31b rotates downward together with the operating body 70 around the engagement points P3 and P4.

そして、操作体70の右端部の下動により、操作体70の特に右側の当接部90が押圧体84の脚部84bを強く押下するが、押圧体84自体の剛性のため脚部84bの押下により押圧体84の脚部84aも同様に押下され、その結果、押ボタン部72の中央B部分を押圧したのと同じように、左右の段部88に当接する両当接片86a,86bを支点として押圧体84の連結部84cが押し上げられ、これによりラバー体66を介してタクトスイッチ58がこれらの復元力や操作力に抗して押圧されてオンする。   Then, due to the downward movement of the right end portion of the operating body 70, the contact portion 90 on the right side of the operating body 70 strongly presses down the leg portion 84b of the pressing body 84. By pressing down, the leg portion 84a of the pressing body 84 is also pressed in the same manner. As a result, both the abutting pieces 86a and 86b that abut on the left and right step portions 88 are pressed in the same manner as when the center B portion of the push button portion 72 is pressed. As a fulcrum, the connecting portion 84c of the pressing body 84 is pushed up, whereby the tact switch 58 is pressed against the restoring force and the operating force via the rubber body 66 and is turned on.

このとき、押ボタン部72のA部分及びC部分をそれぞれ押圧したときの操作荷重を対比すると、押圧部位であるA部分から支点P1,P2までの距離と、押圧部位であるC部分から支点P3,P4までの距離とはほぼ同じになり、しかも押ボタン72のA部分及びC部分をそれぞれ押圧したときの操作体70が受ける反力もほとんど同じであるため、押ボタン部72のA部分及びC部分をそれぞれ押圧したときの操作荷重にほとんど差はない。また、押ボタン部72のA部分及びC部分をそれぞれ押圧したときのストロークに、ほとんど差はない。   At this time, when the operation loads when the A portion and the C portion of the push button portion 72 are respectively pressed are compared, the distance from the A portion that is the pressing portion to the fulcrums P1 and P2, and the C portion that is the pressing portion to the fulcrum P3. , P4, and the reaction force received by the operating body 70 when the A portion and the C portion of the push button 72 are respectively pressed is almost the same. There is almost no difference in the operation load when each part is pressed. Moreover, there is almost no difference in the stroke when the A portion and the C portion of the push button portion 72 are pressed.

また、押ボタン部72のB部分及びA(またはC)部分をそれぞれ押圧したときの操作荷重を対比しても、押ボタン部72のB部分及びA(またはC)部分をそれぞれ押圧したときの操作体70が受ける反力に顕著な差はないことから、押ボタン部72のB部分及びA(またはC)部分をそれぞれ押圧したときの操作荷重の差は小さく、従来のように、押ボタンの操作時における支点が1つで、その支点から遠い部位を押圧したときと近い部位を押圧したときの操作荷重の差ほど大きくなることがない。   Further, even when the operation loads when the B part and the A (or C) part of the push button part 72 are respectively pressed are compared, the B part and the A (or C) part of the push button part 72 are respectively pressed. Since there is no significant difference in the reaction force received by the operating body 70, the difference in the operation load when pressing the B portion and the A (or C) portion of the push button portion 72 is small. There is one fulcrum at the time of the operation, and it does not become as large as the difference in the operation load when the part far from the fulcrum is pressed and when the part close to it is pressed.

よって、押ボタン部72のB部分及びA(またはC)部分をそれぞれ押圧したときの操作荷重は、使用者が違和感を覚えるほど大きくなることがなく、ほぼ同じような操作荷重になる。また、ストロークに関しても、ほとんど差はない。   Therefore, the operation load when the B portion and the A (or C) portion of the push button portion 72 are pressed does not become so large that the user feels uncomfortable, and the operation loads are almost the same. Also, there is almost no difference in stroke.

ところで、図8中に示す押ボタン部72の中央B部分の後側のE部分が押圧されると、押ボタン部72への押圧力が操作体70の後端部寄りに加わり、各係合爪80と各係合凹部78との係合箇所のうち前側、つまり上記したP2,P4を回転中心として、操作体70の後端部がラバー体66の復元力及びタクトスイッチ58の操作力による上向きの付勢力に抗して下向きに回転し、操作体70の後端部が下動しようとする。このとき、分散部材30aの後側の案内部33aが水平方向に摺動し、基部31aが操作体70と共に下動を開始する。この動きに連動して、分散部材30aの前側の案内部33aも水平方向に摺動する。一方、分散部材30bについても、分散部材30aと同様な動作を行う。即ち、分散部材30bの後側の案内部33bが水平方向に摺動し、基部31bが操作体70と共に下動を開始する。この動きに連動して、分散部材30bの前側の案内部33bも水平方向に摺動する。この結果、操作体70は、各係合爪80の各係合凹部78との係合箇所のいずれをも支点とすることがなく、操作体70はラバー体66の復元力及びタクトスイッチ58の操作力による上向きの付勢力に抗して下方に平行移動し、押ボタン部72への押圧力が操作体70の中央付近に位置する両当接部90にそのまま伝わる。   By the way, when the E portion on the rear side of the center B portion of the push button portion 72 shown in FIG. 8 is pressed, the pressing force to the push button portion 72 is applied closer to the rear end portion of the operating body 70, and each engagement. The front side of the engagement portion between the claw 80 and each engagement recess 78, that is, the rear end portion of the operation body 70 with the above-described P2 and P4 as the rotation center, is due to the restoring force of the rubber body 66 and the operation force of the tact switch 58. It rotates downward against the upward biasing force, and the rear end portion of the operating body 70 attempts to move downward. At this time, the guide portion 33a on the rear side of the dispersion member 30a slides in the horizontal direction, and the base portion 31a starts to move downward together with the operating body 70. In conjunction with this movement, the front guide portion 33a of the dispersion member 30a also slides in the horizontal direction. On the other hand, the dispersion member 30b performs the same operation as the dispersion member 30a. That is, the rear guide portion 33 b of the dispersion member 30 b slides in the horizontal direction, and the base portion 31 b starts to move downward together with the operation body 70. In conjunction with this movement, the front guide portion 33b of the dispersion member 30b also slides in the horizontal direction. As a result, the operating body 70 does not use any of the engaging portions of the engaging claws 80 with the engaging recesses 78 as fulcrums, and the operating body 70 has the restoring force of the rubber body 66 and the tact switch 58. Parallel to the downward direction against the upward biasing force by the operating force, the pressing force to the push button portion 72 is transmitted as it is to both contact portions 90 located near the center of the operating body 70.

その結果、操作体70の両当接部90により押圧体84の後端部が押し下げられ、左右の段部88に当接する両当接片86a,86bを支点として押圧体84の連結部84cが押し上げられ、これによりタクトスイッチ58が押圧されてオンする。   As a result, the rear end portion of the pressing body 84 is pushed down by the both contact portions 90 of the operating body 70, and the connecting portion 84 c of the pressing body 84 is supported by using both contact pieces 86 a and 86 b that contact the left and right step portions 88 as fulcrums. As a result, the tact switch 58 is pressed and turned on.

また、図8中に示す押ボタン72の中央B部分の前側のH部分が押圧されると、押ボタン部72への押圧力が操作体70の前端部寄りに加わり、各係合爪80と各係合凹部78との係合箇所のうち前側、つまり上記したP1,P3を回転中心として、操作体70の前端部がラバー体66の復元力及びタクトスイッチ58の操作力による上向きの付勢力に抗して下向きに回転し、操作体70の前端部が下動しようとする。このとき、分散部材30aの前側の案内部33aが水平方向に摺動し、基部31aが操作体70と共に下動を開始する。この動きに連動して、分散部材30aの後側の案内部33aも水平方向に摺動する。一方、分散部材30bについても、分散部材30aと同様な動作を行う。即ち、分散部材30bの前側の案内部33bが水平方向に摺動し、基部31bが操作体70と共に下動を開始する。この動きに連動して、分散部材30bの後側の案内部33bも水平方向に摺動する。この結果、操作体70は、各係合爪80の各係合凹部78との係合箇所のいずれをも支点とすることがなく、操作体70はラバー体66の復元力及びタクトスイッチ58の操作力による上向きの付勢力に抗して下方に平行移動し、押ボタン部72への押圧力が操作体70の中央付近に位置する両当接部90にそのまま伝わる。   When the H portion on the front side of the center B portion of the push button 72 shown in FIG. 8 is pressed, the pressing force to the push button portion 72 is applied closer to the front end portion of the operating body 70, The front side of the engagement portion with each engagement recess 78, that is, the above-described P1, P3 as the rotation center, the front end portion of the operating body 70 is an upward biasing force due to the restoring force of the rubber body 66 and the operating force of the tact switch 58 The front end portion of the operation body 70 tries to move downward. At this time, the front guide portion 33a of the dispersion member 30a slides in the horizontal direction, and the base portion 31a starts to move downward together with the operating body 70. In conjunction with this movement, the guide portion 33a on the rear side of the dispersion member 30a also slides in the horizontal direction. On the other hand, the dispersion member 30b performs the same operation as the dispersion member 30a. That is, the guide portion 33 b on the front side of the dispersion member 30 b slides in the horizontal direction, and the base portion 31 b starts to move downward together with the operation body 70. In conjunction with this movement, the guide portion 33b on the rear side of the dispersion member 30b also slides in the horizontal direction. As a result, the operating body 70 does not use any of the engaging portions of the engaging claws 80 with the engaging recesses 78 as fulcrums, and the operating body 70 has the restoring force of the rubber body 66 and the tact switch 58. Parallel to the downward direction against the upward biasing force by the operating force, the pressing force to the push button portion 72 is transmitted as it is to both contact portions 90 located near the center of the operating body 70.

その結果、操作体70の両当接部90により押圧体84の後端部が押し下げられ、左右の段部88に当接する両当接片86a,86bを支点として押圧体84の連結部84cが押し上げられ、これによりタクトスイッチ58が押圧されてオンする。   As a result, the rear end portion of the pressing body 84 is pushed down by the both contact portions 90 of the operating body 70, and the connecting portion 84 c of the pressing body 84 is supported by using both contact pieces 86 a and 86 b that contact the left and right step portions 88 as fulcrums. As a result, the tact switch 58 is pressed and turned on.

このとき、押ボタン部72のE部分及びH部分をそれぞれ押圧したときの操作荷重を対比すると、E部分及びH部分をそれぞれ押圧したときの操作体70が受ける反力はほとんど同じであるため、押ボタン部72のE部分及びH部分をそれぞれ押圧したときの操作荷重にほとんど差はない。また、ストロークに関してもほとんど差はない。   At this time, when the operation loads when the E portion and the H portion of the push button portion 72 are respectively pressed are compared, the reaction force received by the operating body 70 when the E portion and the H portion are respectively pressed is almost the same. There is almost no difference in the operation load when the E portion and the H portion of the push button portion 72 are pressed. Also, there is almost no difference with respect to the stroke.

また、押ボタン部72のB部分及びE(またはH)部分をそれぞれ押圧したときの操作荷重を対比しても、押ボタン部72のB部分及びE(またはH)部分をそれぞれ押圧したときの操作体70が受ける反力に大きな差はないことから、押ボタン部72のB部分及びE(またはH)部分をそれぞれ押圧したときの操作荷重の差は小さく、従来のように、押ボタンの操作時における支点が1つで、その支点から遠い部位を押圧したときと近い部位を押圧したときの操作荷重の差ほど大きくなることはない。   Further, even when the operation loads when the B portion and the E (or H) portion of the push button portion 72 are respectively pressed are compared, the B portion and the E (or H) portion of the push button portion 72 are respectively pressed. Since there is no great difference in the reaction force received by the operating body 70, the difference in the operation load when pressing the B portion and the E (or H) portion of the push button portion 72 is small. There is only one fulcrum at the time of operation, and it does not become as large as the difference in operation load when a portion far from the fulcrum is pressed and when a portion close to the fulcrum is pressed.

よって、押ボタン72のB部分及びE(またはH)部分をそれぞれ押圧したときの操作荷重は、使用者が違和感を覚えるほど大きくなることがなく、ほぼ同じような操作荷重になる。また、ストロークに関してもほとんど差はない。   Therefore, the operation load when the B portion and the E (or H) portion of the push button 72 are respectively pressed does not become so large that the user feels uncomfortable, and the operation loads are almost the same. Also, there is almost no difference with respect to the stroke.

<仮想隅押しの動作>
ここで、仮想隅押しの動作とは、押ボタン部72の実際の隅押しの動作ではなく、操作体70の正方形状を基準として設定した押圧部位における隅押しの動作を意味する。
さらに、図8中に示す押ボタン部72の左後側のD部分が押圧されると、押ボタン部72への押圧力が操作体70の左後端部寄りに加わるため、押圧体84の脚部84aを介して操作体70の左後端部に加わる付勢力に抗して、操作体70の左後端部が右前側の両係合爪80と両係合凹部78との係合箇所P2を回転中心として下向きに回転し、操作体70の左後端部が下動しようとする。このとき、分散部材30aの後側の案内部33aが水平方向に摺動し、基部31aが操作体70と共に下動を開始する。この動きに連動して、分散部材30aの前側の案内部33aも水平方向に摺動する。この結果、操作体70は係合箇所P1,P2を回転中心として下向きに回転しつつ下動する。換言すれば、D部分が押圧された場合、D部分への操作荷重が分散部材30aによって押ボタン部72の左側辺(脚部84aの延在方向に相当)に均一に分散されたことを意味する。
<Virtual corner push operation>
Here, the virtual corner pushing operation means not the actual corner pushing operation of the push button unit 72 but the corner pushing operation at the pressing portion set on the basis of the square shape of the operating body 70.
Further, when the D portion on the left rear side of the push button portion 72 shown in FIG. 8 is pressed, the pressing force to the push button portion 72 is applied closer to the left rear end portion of the operating body 70, so The left rear end portion of the operation body 70 is engaged with the engagement claws 80 on the right front side and the engagement recesses 78 against the biasing force applied to the left rear end portion of the operation body 70 via the leg portion 84a. The portion P2 rotates downward about the rotation center, and the left rear end portion of the operating body 70 tries to move downward. At this time, the guide portion 33a on the rear side of the dispersion member 30a slides in the horizontal direction, and the base portion 31a starts to move downward together with the operating body 70. In conjunction with this movement, the front guide portion 33a of the dispersion member 30a also slides in the horizontal direction. As a result, the operating body 70 moves downward while rotating downward with the engagement points P1 and P2 as rotation centers. In other words, when the D portion is pressed, the operation load applied to the D portion is uniformly distributed by the dispersing member 30a on the left side of the push button portion 72 (corresponding to the extending direction of the leg portion 84a). To do.

一方、図8中に示す押ボタン72の左前側のG部分が押圧されると、押ボタン部72への押圧力が操作体70の左前端部寄りに加わるため、押圧体84の脚部84aを介して操作体70の左前端部に加わる付勢力に抗して、操作体70の左前端部が右後側の両係合爪80と両係合凹部78との係合箇所P1を回転中心として下向きに回転し、操作体70の左前端部が下動しようとする。このとき、分散部材30aの前側の案内部33aが水平方向に摺動し、基部31aが操作体70と共に下動を開始する。この動きに連動して、分散部材30aの後側の案内部33aも水平方向に摺動する。この結果、操作体70は係合箇所P1,P2を回転中心として下向きに回転しつつ下動する。換言すれば、G部分が押圧された場合、G部分への操作荷重が分散部材30aによって押ボタン部72の左側辺(脚部84aの延在方向に相当)に均一に分散されたことを意味する。   On the other hand, when the G portion on the left front side of the push button 72 shown in FIG. 8 is pressed, the pressing force to the push button portion 72 is applied closer to the left front end portion of the operating body 70, and thus the leg portion 84 a of the pressing body 84. The left front end portion of the operating body 70 rotates the engagement point P1 between the right engagement claws 80 and the engagement recesses 78 against the urging force applied to the left front end portion of the operating body 70 via Rotating downward as the center, the left front end of the operating body 70 tries to move downward. At this time, the front guide portion 33a of the dispersion member 30a slides in the horizontal direction, and the base portion 31a starts to move downward together with the operating body 70. In conjunction with this movement, the guide portion 33a on the rear side of the dispersion member 30a also slides in the horizontal direction. As a result, the operating body 70 moves downward while rotating downward with the engagement points P1 and P2 as rotation centers. In other words, when the G portion is pressed, the operation load applied to the G portion is uniformly distributed by the dispersing member 30a on the left side of the push button portion 72 (corresponding to the extending direction of the leg portion 84a). To do.

また、図8中に示す押ボタン72の右後側のF部分が押圧されると、押ボタン部72への押圧力が操作体70の右後端部寄りに加わるため、押圧体84の脚部84bを介して操作体70の右後端部に加わる付勢力に抗して、操作体70の右後端部が左前側の両係合爪80と両係合凹部78との係合箇所P4を回転中心として下向きに回転し、操作体70の右後端部が下動しようとする。このとき、分散部材30bの後側の案内部33bが水平方向に摺動し、基部31bが操作体70と共に下動を開始する。この動きに連動して、分散部材30bの前側の案内部33bも水平方向に摺動する。この結果、操作体70は係合箇所P3,P4を回転中心として下向きに回転しつつ下動する。換言すれば、F部分が押圧された場合、F部分への操作荷重が分散部材30bによって押ボタン部72の右側辺(脚部84bの延在方向に相当)に均一に分散されたことを意味する。   Further, when the F portion on the right rear side of the push button 72 shown in FIG. 8 is pressed, the pressing force to the push button portion 72 is applied closer to the right rear end portion of the operating body 70, so The right rear end portion of the operation body 70 is engaged with the left front engaging claws 80 and the engagement recesses 78 against the urging force applied to the right rear end portion of the operation body 70 via the portion 84b. It rotates downward about P4 as the center of rotation, and the right rear end of the operating body 70 attempts to move downward. At this time, the guide portion 33b on the rear side of the dispersion member 30b slides in the horizontal direction, and the base portion 31b starts to move downward together with the operating body 70. In conjunction with this movement, the front guide portion 33b of the dispersion member 30b also slides in the horizontal direction. As a result, the operating body 70 moves downward while rotating downward with the engagement points P3 and P4 as the center of rotation. In other words, when the F portion is pressed, the operation load applied to the F portion is uniformly distributed to the right side of the push button portion 72 (corresponding to the extending direction of the leg portion 84b) by the dispersing member 30b. To do.

さらに、図8中に示す押ボタン72の右前側のI部分が押圧されると、押ボタン部7への押圧力が操作体70の右前端部寄りに加わるため、押圧体84の脚部84bを介して操作体70の右前端部に加わる付勢力に抗して、操作体70の右前端部が左後側の両係合爪80と両係合凹部78との係合箇所P3を回転中心として下向きに回転し、操作体70の右前端部が下動しようとする。このとき、分散部材30bの前側の案内部33bが水平方向に摺動し、基部31bが操作体70と共に下動を開始する。この動きに連動して、分散部材30bの後側の案内部33bも水平方向に摺動する。この結果、操作体70は係合箇所P3,P4を回転中心として下向きに回転しつつ下動する。換言すれば、I部分が押圧された場合、I部分への操作荷重が分散部材30bによって押ボタン部72の左側辺(脚部84bの延在方向に相当)に均一に分散されたことを意味する。   Further, when the I portion on the right front side of the push button 72 shown in FIG. 8 is pressed, the pressing force on the push button portion 7 is applied closer to the right front end portion of the operating body 70, so that the leg portion 84 b of the pressing body 84. The right front end of the operating body 70 rotates the engagement portion P3 between the left rear engaging claws 80 and the both engaging recesses 78 against the biasing force applied to the right front end of the operating body 70 via Rotating downward as the center, the right front end portion of the operation body 70 tries to move downward. At this time, the guide portion 33b on the front side of the dispersion member 30b slides in the horizontal direction, and the base portion 31b starts to move downward together with the operating body 70. In conjunction with this movement, the guide portion 33b on the rear side of the dispersion member 30b also slides in the horizontal direction. As a result, the operating body 70 moves downward while rotating downward with the engagement points P3 and P4 as the center of rotation. In other words, when the I portion is pressed, it means that the operation load applied to the I portion is uniformly distributed to the left side of the push button portion 72 (corresponding to the extending direction of the leg portion 84b) by the dispersing member 30b. To do.

そして、操作体70の左後端部、右後端部、左前端部、右前端部のいずれが下動しても、押圧体84自体がある程度剛性を有するため、図8中の押ボタン部72のA,C部分を押圧した場合と同様に、押圧体84全体が押下されることになり、その結果、押ボタン部72の中央B部分を押圧したのと同じように、左右の段部88に当接する両当接片86a,86bを支点として押圧体84の連結部84cが押し上げられ、これによりラバー体66を介してタクトスイッチ58がこれらの復元力や操作力に抗して押圧されてオンする。   Since the pressing body 84 itself has some rigidity even if any of the left rear end portion, right rear end portion, left front end portion, and right front end portion of the operating body 70 moves down, the push button portion in FIG. As in the case where the A and C portions of 72 are pressed, the entire pressing body 84 is pressed, and as a result, the left and right step portions are the same as when the central B portion of the push button portion 72 is pressed. The connecting portion 84c of the pressing body 84 is pushed up with the two abutting pieces 86a and 86b abutting on the fulcrum 88, whereby the tact switch 58 is pressed against these restoring force and operating force via the rubber body 66. Turn on.

このとき、押ボタン部72のD部分及びG部分をそれぞれ押圧したときの操作荷重を対比すると、D部分及びG部分をそれぞれ押圧したときの操作体70が受ける反力はほとんど同じであるため、押ボタン部72のD部分及びG部分をそれぞれ押圧したときの操作荷重にほとんど差はない。また、ストロークに関しても、ほとんど差はない。
また、押ボタン部72のA部分及びD(またはG)部分をそれぞれ押圧したときの操作荷重を対比すると、A部分及びD(またはG)部分をそれぞれ押圧したときの操作体70が受ける反力はほとんど同じであるため、押ボタン部72のA部分及びD(またはG)部分をそれぞれ押圧したときの操作荷重にほとんど差はない。また、ストロークに関しても、ほとんど差はない。
At this time, when the operation loads when pressing the D portion and G portion of the push button portion 72 are compared, the reaction force received by the operating body 70 when pressing the D portion and G portion is almost the same. There is almost no difference in the operation load when the D portion and G portion of the push button portion 72 are pressed. Also, there is almost no difference in stroke.
Further, when the operation loads when the A portion and the D (or G) portion of the push button portion 72 are respectively pressed are compared, the reaction force received by the operating body 70 when the A portion and the D (or G) portion are respectively pressed. Are almost the same, there is almost no difference in the operation load when the A portion and the D (or G) portion of the push button portion 72 are respectively pressed. Also, there is almost no difference in stroke.

また、押ボタン部72のF部分及びI部分をそれぞれ押圧したときの操作荷重を対比すると、F部分及びI部分をそれぞれ押圧したときの操作体70が受ける反力はほとんど同じであるため、押ボタン部72のF部分及びI部分をそれぞれ押圧したときの操作荷重にほとんど差はない。また、ストロークに関しても、ほとんど差はない。   Further, when the operation loads when the F portion and the I portion of the push button portion 72 are respectively pressed are compared, the reaction force received by the operating body 70 when the F portion and the I portion are respectively pressed is almost the same. There is almost no difference in the operation load when the F part and the I part of the button part 72 are respectively pressed. Also, there is almost no difference in stroke.

また、押ボタン部72のC部分及びF(またはI)部分をそれぞれ押圧したときの操作荷重を対比すると、C部分及びF(またはI)部分をそれぞれ押圧したときの操作体70が受ける反力はほとんど同じであるため、押ボタン部72のC部分及びF(またはI)部分をそれぞれ押圧したときの操作荷重にほとんど差はない。また、ストロークに関しても、ほとんど差はない。   Further, when the operation loads when the C portion and the F (or I) portion of the push button portion 72 are respectively pressed are compared, the reaction force received by the operating body 70 when the C portion and the F (or I) portion are respectively pressed. Are almost the same, there is almost no difference in the operation load when the C portion and the F (or I) portion of the push button portion 72 are respectively pressed. Also, there is almost no difference in stroke.

また、押ボタン部72のD部分及びF部分をそれぞれ押圧したときの操作荷重を対比すると、押ボタン部72のD部分及びF部分をそれぞれ押圧したときの操作体70が受ける反力もほとんど同じであるため、押ボタン部72のD部分及びF部分をそれぞれ押圧したときの操作荷重にほとんど差はない。また、ストロークに関しても、ほとんど差はない。   Further, when the operation loads when the D portion and the F portion of the push button portion 72 are respectively pressed are compared, the reaction force received by the operating body 70 when the D portion and the F portion of the push button portion 72 are respectively pressed is almost the same. Therefore, there is almost no difference in the operation load when the D portion and the F portion of the push button portion 72 are pressed. Also, there is almost no difference in stroke.

また、押ボタン部72のG部分及びI部分をそれぞれ押圧したときの操作荷重を対比すると、押ボタン部72のG部分及びI部分をそれぞれ押圧したときの操作体70が受ける反力もほとんど同じであるため、押ボタン部72のG部分及びI部分をそれぞれ押圧したときの操作荷重にほとんど差はない。また、ストロークに関しても、ほとんど差はない。   Further, when the operation loads when the G portion and the I portion of the push button portion 72 are respectively pressed are compared, the reaction force received by the operating body 70 when the G portion and the I portion of the push button portion 72 are respectively pressed is almost the same. Therefore, there is almost no difference in the operation load when the G portion and the I portion of the push button portion 72 are pressed. Also, there is almost no difference in stroke.

また、押ボタン部72のB部分及びD(またはF)部分をそれぞれ押圧したときの操作荷重を対比しても、押ボタン部72のB部分及びD(またはF)部分をそれぞれ押圧したときの操作体70が受ける反力に大きな差はないことから、押ボタン部72のB部分及びD(またはF)部分をそれぞれ押圧したときの操作荷重の差は小さく、従来のように、押ボタンの操作時における支点が1つで、その支点から遠い部位を押圧したときと近い部位を押圧したときの操作荷重の差ほど大きくなることはない。   Further, even when the operation loads when the B portion and the D (or F) portion of the push button portion 72 are respectively pressed are compared, the B portion and the D (or F) portion of the push button portion 72 are respectively pressed. Since there is no great difference in the reaction force received by the operating body 70, the difference in the operation load when pressing the B portion and D (or F) portion of the push button portion 72 is small. There is only one fulcrum at the time of operation, and it does not become as large as the difference in operation load when a portion far from the fulcrum is pressed and when a portion close to the fulcrum is pressed.

よって、押ボタン部72のB部分及びD(またはF)部分をそれぞれ押圧したときの操作荷重は、使用者が違和感を覚えるほど大きくなることがなく、ほぼ同じような操作荷重になる。また、ストロークに関しても、ほとんど差はない。なお、押ボタン部72のB部分及びG(またはI)部分をそれぞれ押圧したときの操作荷重を対比しても、同様に操作荷重にほとんど差はなく、ストロークに関してもほとんど差はない。   Therefore, the operation load when the B portion and the D (or F) portion of the push button portion 72 are pressed does not become so large that the user feels uncomfortable, and the operation loads are almost the same. Also, there is almost no difference in stroke. Even if the operation loads when the B portion and the G (or I) portion of the push button portion 72 are pressed are compared, there is almost no difference in the operation load, and there is almost no difference in the stroke.

このように仮想隅部を押した場合、仮想隅部のみが大きく沈み込むことはなく、脚部84a,84bの延在方向に対応する押ボタン部72の端部全体が均一に下向きに回転し、この結果、仮想隅部を押した場合のストロークは、脚部84a,84bの延在方向に対応する押ボタン部72の仮想端部の中央部(例えばD又はG部分を押圧した場合はA部分、F又はI部分を押圧した場合はC部分に相当)を押した場合におけるストロークとほぼ同様となり、また、仮想隅部を押した場合の操作荷重は、脚部の延在方向に対応する押ボタン部72の仮想端部の中央部(例えばD又はG部分を押圧した場合はA部分、F又はI部分を押圧した場合はC部分に相当)を押した場合における操作荷重とほぼ同様となる。加えて、その他の任意の押圧部位に拘らず、操作荷重が均一で且つストロークのバラツキもほとんどない。そして、上記の作用・効果は、押ボタン部72のサイズに影響されないことから、押ボタン部72が大型化しても、押圧部位に関係なく操作荷重を均一にでき、且つストロークのバラツキを抑えた押ボタンスイッチ装置を実現することができる。   When the virtual corner portion is pushed in this way, only the virtual corner portion does not sink greatly, and the entire end portion of the push button portion 72 corresponding to the extending direction of the leg portions 84a and 84b rotates uniformly downward. As a result, the stroke when the virtual corner portion is pushed is the center portion of the virtual end portion of the push button portion 72 corresponding to the extending direction of the leg portions 84a and 84b (for example, A when the D or G portion is pressed). When the part, F or I part is pressed, this corresponds to the part C), and the operation load when the virtual corner part is pressed corresponds to the extending direction of the leg part. It is almost the same as the operation load when the center part of the virtual end part of the push button part 72 (for example, the A part when pressing the D or G part, and the C part when pressing the F or I part) is pressed. Become. In addition, the operation load is uniform and there is almost no variation in stroke regardless of any other pressing portion. And since the said effect | action and effect are not influenced by the size of the pushbutton part 72, even if the pushbutton part 72 enlarged, the operation load could be made uniform irrespective of the press part, and the variation in the stroke was suppressed. A push button switch device can be realized.

上記のA、B、C、D、E、F、G、H、I部分を押した場合(仮想端押し及び仮想隅押し)の操作荷重およびストロークに関する説明は、押ボタン部72の現実の端部及び隅部であるA1、C1、D1、E1、F1、G1、H1、I1部分(図8参照)をそれぞれ押した場合(現実の端押し及び現実の隅押し)についても当てはまる。
従って、押圧部位に関係なく操作荷重を均一にでき、且つストロークのバラツキを抑えた押ボタンスイッチ装置を実現することができる。
The explanation regarding the operation load and stroke when pressing the above-mentioned A, B, C, D, E, F, G, H, and I portions (virtual end pushing and virtual corner pushing) This also applies to the case where the portions A1, C1, D1, E1, F1, G1, H1, and I1 (see FIG. 8) are pressed (actual end pushing and actual corner pushing).
Therefore, it is possible to realize a push button switch device that can make the operation load uniform regardless of the pressed part and suppress the variation in stroke.

<操作荷重の可変設定>
このような操作荷重は、上記したように、押圧体84の支点の位置を適宜変更することで任意に可変設定することができる。つまり、押圧体84の作用点側に加わるべきタクトスイッチ58の操作力とラバー体66の復元力との合力は一定であることから、例えば操作荷重を現状よりも大きくしたいときには支点を力点側に寄せればよく、操作荷重を現状よりも小さくしたいときには支点を作用点側に寄せればよく、支点位置を変えることにより、非常に広い範囲(前記合力よりも大きい範囲、小さい範囲のどちらでも)で、操作荷重を可変設定できる。そして、支点の位置調整は、段部88を削ったり肉盛りするなどで対応可能である。
<Variable setting of operation load>
As described above, such an operation load can be arbitrarily variably set by appropriately changing the position of the fulcrum of the pressing body 84. That is, the resultant force of the operating force of the tact switch 58 to be applied to the action point side of the pressing body 84 and the restoring force of the rubber body 66 is constant. If you want to reduce the operating load from the current level, move the fulcrum to the point of action, and change the position of the fulcrum. The operation load can be variably set. The position of the fulcrum can be adjusted by shaving or building up the stepped portion 88.

また望ましくは、支点となる両段部88の位置を前後方向に移動自在であって、かつ、力点、作用点間の任意の位置で両段部88の位置を固定可能に、両段部88をスイッチ本体ケース50に設けるのがよい。例えば、スイッチ本体ケース50の前後方向のスライド溝を設け、このスライド溝に沿って両段部を同時にスライドできるように支持機構により支持し、スライド溝の途中数箇所に係止部を設けて、いずれかの係止部に支持機構を係止して段部の位置を固定するなどすればよい。   Desirably, both the step portions 88 can be moved in the front-rear direction, and the positions of both step portions 88 can be fixed at any position between the force point and the action point. Is preferably provided in the switch body case 50. For example, a slide groove in the front-rear direction of the switch body case 50 is provided, supported by a support mechanism so that both step portions can be simultaneously slid along the slide groove, and locking portions are provided at several positions in the slide groove. The position of the stepped portion may be fixed by locking the support mechanism to any one of the locking portions.

従って、上記した実施形態によれば、押ボタン部72の押圧部位に応じて操作体70の回転中心となる係合箇所の位置を切り換えることができるため、押ボタン部72の中央以外の端部や隅部を押圧した場合であっても、押圧時の操作荷重を、押ボタン部72の中央を押圧したのとほぼ同じにすることができ、押ボタン部72の押圧部位に関係なく操作荷重をほぼ均一にすることができる。   Therefore, according to the above-described embodiment, the position of the engaging portion that becomes the rotation center of the operating body 70 can be switched according to the pressed portion of the push button portion 72, and therefore the end portion other than the center of the push button portion 72. Even when the corner is pressed, the operation load at the time of pressing can be made substantially the same as when the center of the push button portion 72 is pressed, and the operation load regardless of the pressing portion of the push button portion 72. Can be made substantially uniform.

また、タクトスイッチ58の操作力とラバー体66の復元力との合力を、押圧体84を介して操作体70の付勢力としているため、操作体70の付勢のためにばね等の付勢手段を専用に設ける必要がなく、部品点数の低減を図ることができて装置を安価に構成することが可能になる。   In addition, since the resultant force of the operating force of the tact switch 58 and the restoring force of the rubber body 66 is used as the biasing force of the operating body 70 via the pressing body 84, an urging force such as a spring is used to bias the operating body 70. There is no need to provide a dedicated means, the number of parts can be reduced, and the apparatus can be configured at low cost.

さらに、押圧体84の支点の位置を適宜調整することで、スイッチ操作荷重を可変設定することができ、使用者の好みや押ボタンスイッチ装置の使用状況に応じて操作荷重の可変設定を容易に行うことが可能になる。   Furthermore, by appropriately adjusting the position of the fulcrum of the pressing body 84, the switch operation load can be variably set, and the operation load can be easily set according to the user's preference and the use situation of the push button switch device. It becomes possible to do.

また、押ボタン部72を押圧し続けたときに、押圧体84の連結部84cがタクトスイッチ58に当接しつつ、操作体70を介して押圧体84の脚部84a,84bの後端に継続的に強い荷重がかかり続ける状況になることがあるが、例えば押圧体を矩形枠状とした場合であって、押ボタン部を押圧し続けたときに、矩形枠状の押圧体の両端部分が内蔵スイッチなどに当接してそれ以上の押下が阻止されつつ、矩形枠状の押圧体の中央部に継続的に強い荷重がかかり続ける状況に成る構成、つまり押圧体の両端部分が支持された状態で押圧体の中央部に荷重がかかる、いわゆる両持ち状態の押ボタンスイッチ装置と比較して、上記した実施形態における押圧体84は、段部88で支持され押圧体84の後端(脚部84a,84bの後端)に荷重がかかる、いわゆる片持ち状態であり、押圧体84全体に及ぶ負荷は大幅に軽減される。その結果、押圧体84の長寿命化を図ることができ、スイッチ装置全体としての長寿命化が望める。   Further, when the push button portion 72 is continuously pressed, the connecting portion 84c of the pressing body 84 is in contact with the tact switch 58 and is continued to the rear ends of the leg portions 84a and 84b of the pressing body 84 via the operating body 70. However, when the pressing body has a rectangular frame shape, for example, when the push button portion is continuously pressed, both end portions of the rectangular frame-shaped pressing body are A configuration in which a strong load is continuously applied to the central part of the rectangular frame-shaped pressing body while being pressed against a built-in switch or the like and further pressing is prevented, that is, both end portions of the pressing body are supported Compared with a so-called both-end supported push button switch device in which a load is applied to the center of the pressing body, the pressing body 84 in the above-described embodiment is supported by the stepped portion 88 and the rear end (leg portion) of the pressing body 84. 84a, 84b) Takes a so-called cantilever state, the load-wide pressing body 84 is greatly reduced. As a result, the lifetime of the pressing body 84 can be increased, and the lifetime of the entire switch device can be increased.

さらに、各LED60をタクトスイッチ58と同じプリント基板56に実装し、導光部材62により各LED60の光を押ボタン部72まで導光するようにしたため、各LED60をタクトスイッチ58と別の回路基板に実装して押ボタン部72の下方に配置したり、押ボタン部72の下方以外でタクトスイッチ58とは異なる位置に配置する場合に比べ
、装置の大型化を招くこともなく、より薄型の押ボタンスイッチ装置を得ることができる。
Furthermore, each LED 60 is mounted on the same printed circuit board 56 as the tact switch 58, and the light of each LED 60 is guided to the push button portion 72 by the light guide member 62. Therefore, each LED 60 is separated from the tact switch 58 by a circuit board. Compared with the case where it is mounted and disposed below the push button portion 72 or disposed at a position different from the tact switch 58 other than below the push button portion 72, the apparatus is not increased in size and is thinner. A push button switch device can be obtained.

また、裏面カバー94側に第1フック体106を設けると共に、スイッチ本体ケース50側に第2フック体108を設け、裏面カバー94をスイッチ本体ケース50に対して線状ばね100の付勢力に抗してスライドさせた状態で、第1フック体106を所定の箇所に引っ掛けつつ第2フック体108も引っ掛けることができるため、押ボタンスイッチ装置を所定位置に簡単に取り付けることができるため、スイッチ装置の取付作業を非常に容易に行うことができる。   In addition, the first hook body 106 is provided on the back cover 94 side, and the second hook body 108 is provided on the switch body case 50 side, so that the back cover 94 resists the urging force of the linear spring 100 against the switch body case 50. Since the second hook body 108 can be hooked while the first hook body 106 is hooked at a predetermined position in the state of being slid, the push button switch device can be easily attached at a predetermined position. The mounting work can be performed very easily.
