ことを特徴とする多方向入力スイッチ装置が提供される。
【０００６】
請求項２の発明によれば、請求項１の発明において、端部スイッチと中央スイッチが、同じスイッチとされ、それぞれ、スイッチケーシングと、該スイッチケーシングの内部でバネにより付勢される被押圧部材を有する、ことを特徴とする請求項１に記載の多方向入力スイッチ装置が提供される。
【０００９】
【発明の実施の形態】
以下、添付の図面を参照して本発明の実施の形態について説明する。
図１は本発明の実施の形態の断面図、図２は分解図であって、図３は斜視図である。
基板１０に４つの端部スイッチ１００ａ〜１００ｄが十字の端部位置に取付けられ、その中心部に１つの中央スイッチ１００ｅが取付けられている。
【００１０】
各スイッチは、ケーシング１１０内でバネ１２０により付勢されている被押圧部材１３０を有する。被押圧部材１３０はバネ１２０を受けるフランジ部１３１と、フランジ部１３１からフランジ部１３１より細い径で、ケーシング１１０の上側部材１１１の開口１１２を通って反基板側に延伸している突出部１３２を有し、突出部１３２の反基板側に後述する押圧部材で押圧される被押圧面１３３が形成されている。
【００１１】
被押圧部材１３０のフランジ部１３１の反基板側の面１３４には接点部材１３５が付設されていて、ケーシング１１０の底部材１１３には板バネ１１４を介して接点部材１１５が取付けられている。接点部材１３５が可動側接点で接点部材１１５が固定側接点である。接点部材１３５と接点部材１１５にはそれぞれ外部導線が接続されている。
【００１２】
端部スイッチ押圧部材２００はボス部２１０と４つのアーム２２０ａ〜２２０ｄを有し、ボス部２１０と４つのアーム２２０ａ〜２２０ｄは反基板側に凸の半球面部材２３０を介して結合されている。４つのアーム２２０ａ〜２２０ｄはそれぞれ先端の基板側に押圧面２２１を有する。
【００１３】
中央スイッチ押圧部材３００は、中央スイッチ１００ｅの被押圧面に接する面３１１を有する当接部３１０と、該当接部３１０から縮径されて反基板側に延伸するスティック部３２０とを有し、該スティック部３２０は端部スイッチ押圧部材２００のボス部２１０を貫通して形成されているスティック支持穴２１１に摺動可能に係合している。当接部３１０の反基板側の環状の面３１２は端部スイッチ押圧部材２００の半球面部材２３０の内側面２３１と相補的に係合する面にされている。
【００１４】
スティック部３２０の反基板側の端部には、操作ボタン５００が取付けられていて、操作ボタンの表面には多数の点状の突起が５１０が形成されているが、点状の突起ではなくて図５に示すような線状の突起とすることもできる。
【００１５】
一方、基板１０には保持部材４００が４本の足４１０を基板１０に形成された穴１１（図２参照）に嵌合し、爪４１１を基板１０の下面１２に引っ掛けて取付けられている。保持部材４００の上面部材４２０は端部スイッチ押圧部材２００のボス部２１０が最大に傾斜しても接しない大きさの穴４２１を有し、該穴４２１の基板側には、端部スイッチ押圧部材２００の半球面部材２３０と接する円形の縁４２２が設けられている。
【００１６】
そして、ニュートラル状態において、半球面部材２３０が縁４２２に接する、端部スイッチ押圧部材２００の各アーム２２０ａ〜２２０ｄが端部スイッチ１００ａ〜１００ｄのそれぞれの被押圧面１３３を若干押圧するように、縁４２２が、形成されている。このようにすることにより、端部スイッチ押圧部材２００は各スイッチのバネ１２０で縁４２２に押し付けられるのでニュートラル状態においてぐらつかない。
また、端部スイッチ１００ａ〜１００ｄのいずれかを押圧したときは、さらに大きなバネ力が作用するのでぐらつかない。
【００１７】
また、中央スイッチ押圧部材３００についてもニュートラル状態で中央スイッチ１００ｅのバネ１２０の付勢力を受けるように当接部３１０が形成されている。このようにすることにより、反基板側の環状の面３１２が端部スイッチ押圧部材２００の半球面部材２３０の内側面２３１と接するのでガタが発生しない。
【００１８】
本発明の多方向入力スイッチの実施の形態は、上記のように形成されており、中央スイッチ押圧部材３００のスティック部３２０を、傾けることにより、端部スイッチ１００ａ〜１００ｄの内の傾けた方向のスイッチを閉成せしめることができ、また、スティック部３２０を押し下げることにより、中央スイッチ１００ｅを閉成せしめることができる。
【００１９】
図からも容易に理解されるように、端部スイッチ１００ａ〜１００ｄと中央スイッチ１００ｅは全く同じものを使用することができるという利点を有している。また、中央スイッチ１００ｅをダミーのスイッチにすれば、他の部品を全く買えずに４方向入力スイッチとすることができる。
【００２０】
図４は、上記の多方向入力スイッチを、マウスに取付けた様子を示したものであって、例えば、カーソルの移動に加えて、移動した位置での決定入力を、おこなうことができる。
【００２１】
【発明の効果】
各請求項に記載の多方向入力スイッチ装置は、十字の４つの端部位置と中央位置にあるように基板に取付けられた４つの端部スイッチと中央スイッチと、４つのアームの先に、４つの端部スイッチの各押圧面に接する当接面を有する十字形状の端部スイッチ押圧部材と、中央スイッチの押圧面に当接する当接面を有する中央スイッチ押圧部材と、基板に取付けられていて端部スイッチと協働して端部スイッチ押圧部材を所定の姿勢に保持する保持部材と、を有し、各スイッチは反基板側に弾性部材に付勢されている押圧面を有し、該押圧面の内側に可動端子が取付けられ、該可動端子は押圧面の外側が端部または中央スイッチ押圧部材で押圧されたときに固定端子と接触可能であって、端部スイッチ押圧部材は、ボス部と、該ボス部に反基板側に凸の半球面部材を介して取付けられた各十字方向に延伸する４本のアームとを有し、４本のアームの先端の基板側の面がスイッチの被押圧面に接するようにされていて、中央スイッチ押圧部材は、基板側に中央スイッチに接する面を有する当接部と、該当接部から縮径されて反基板側に延伸するスティック部とを有し、該スティック部は端部スイッチ押圧部材のボス部を貫通して形成されたスティック支持穴に摺動可能に係合し、保持部材が上面部材を有し、上面部材が端部スイッチ押圧部材のボス部が最大に傾斜しても接しない大きさの穴を有し、該穴の基板側に縁が形成され、該縁には端部スイッチ押圧部材の半球面部が当接し、ニュートラル状態において、端部スイッチ押圧部材の各アームが端部スイッチのそれぞれの被押圧面を若干押圧するように、縁が形成されていて、保持部材が４本の足を有し、該４本の足が基板の端部スイッチの間に設けられている穴に嵌合され、足の爪が基板の下面に引っ掛けられる、
したがって、各スイッチは基板に固定されており、作動の信頼性が高い。また、ニュートラル状態を保つのに各スイッチの弾性部材を利用しているので、部品数が少なく低コストで製造できる。
特に、請求項２のように、端部スイッチと中央スイッチを同じスイッチとすれば、部品が共通化でき、さらに低コストで製造できる。

Four end switches 100a to 100d are attached to the substrate 10 at the positions of the cross ends, and one central switch 100e is attached to the center thereof.
[0010]
Each switch has a pressed member 130 that is biased by a spring 120 within the casing 110. The pressed member 130 includes a flange portion 131 that receives the spring 120, and a protruding portion 132 that is narrower than the flange portion 131 from the flange portion 131 and extends toward the opposite side of the substrate 110 through the opening 112 of the upper member 111 of the casing 110. And a pressed surface 133 that is pressed by a pressing member, which will be described later, is formed on the opposite side of the protrusion 132 from the substrate.
[0011]
A contact member 135 is attached to the surface 134 of the flange 131 of the pressed member 130 on the side opposite to the substrate, and a contact member 115 is attached to the bottom member 113 of the casing 110 via a leaf spring 114. The contact member 135 is a movable contact, and the contact member 115 is a fixed contact. External conductors are connected to the contact member 135 and the contact member 115, respectively.
[0012]
The end switch pressing member 200 has a boss portion 210 and four arms 220a to 220d, and the boss portion 210 and the four arms 220a to 220d are coupled to each other via a hemispherical member 230 that is convex on the opposite side of the substrate. Each of the four arms 220a to 220d has a pressing surface 221 on the substrate side at the tip.
[0013]
The central switch pressing member 300 includes a contact portion 310 having a surface 311 that contacts the pressed surface of the central switch 100e, and a stick portion 320 that is reduced in diameter from the corresponding contact portion 310 and extends toward the opposite substrate side. The stick part 320 is slidably engaged with a stick support hole 211 formed through the boss part 210 of the end switch pressing member 200. An annular surface 312 on the side opposite to the substrate of the contact portion 310 is a surface that complementarily engages with the inner surface 231 of the hemispherical member 230 of the end switch pressing member 200.
[0014]
An operation button 500 is attached to the end of the stick part 320 on the opposite side of the board, and a number of dot-like protrusions 510 are formed on the surface of the operation button. It can also be a linear protrusion as shown in FIG.
[0015]
On the other hand, a holding member 400 is attached to the substrate 10 by fitting four legs 410 into holes 11 (see FIG. 2) formed in the substrate 10 and hooking the claws 411 on the lower surface 12 of the substrate 10. The upper surface member 420 of the holding member 400 has a hole 421 having a size that does not contact even when the boss portion 210 of the end switch pressing member 200 is tilted to the maximum, and the end switch pressing member is disposed on the substrate side of the hole 421. A circular edge 422 in contact with the 200 hemispherical members 230 is provided.
[0016]
And, in the neutral state, the hemispherical member 230 is in contact with the edge 422 so that the arms 220a to 220d of the end switch pressing member 200 slightly press the pressed surfaces 133 of the end switches 100a to 100d. 422 is formed. By doing so, the end switch pressing member 200 is pressed against the edge 422 by the spring 120 of each switch and thus does not wobble in the neutral state.
Further, when any one of the end switches 100a to 100d is pressed, a larger spring force acts so that it does not wobble.
[0017]
The central switch pressing member 300 is also formed with a contact portion 310 so as to receive the biasing force of the spring 120 of the central switch 100e in the neutral state. By doing so, the annular surface 312 on the side opposite to the substrate is in contact with the inner surface 231 of the hemispherical member 230 of the end switch pressing member 200, so that no play occurs.
[0018]
The embodiment of the multi-directional input switch of the present invention is formed as described above. By tilting the stick portion 320 of the central switch pressing member 300, the end switch 100a to 100d can be moved in the tilted direction. The switch can be closed, and the central switch 100e can be closed by depressing the stick portion 320.
[0019]
As can be easily understood from the figure, the end switches 100a to 100d and the central switch 100e have the advantage that the same switches can be used. Further, if the central switch 100e is a dummy switch, the four-way input switch can be obtained without buying any other parts.
[0020]
