Description

【０００１】
【発明の属する技術分野】
本発明は、回転式スイッチ等の回転式電子部品に押釦スイッチ機能を設けた押釦スイッチ付き回転式電子部品に関するものである。
【０００２】
【従来の技術】
従来、回転式スイッチのつまみを回転することによってそのスイッチの切替えを行なうと共に、このつまみを半径方向に押圧することで別の押釦スイッチをオンオフする構造の押釦スイッチ付き回転式電子部品が開発され、使用されている。
【０００３】
この種の押釦スイッチ付き回転式電子部品は、例えば携帯電話のメニュー選択・設定スイッチや、ビデオカメラのマニュアルフォーカス調整・設定スイッチや、カメラのアイリス調整・設定スイッチなどとして用いられる。即ち例えば携帯電話の場合で言えば、つまみを回転することでメニューを選択し、その状態でつまみを半径方向に押圧することでそのメニューを設定するように用いられる。
【０００４】
そして本願出願人はこの種の押釦スイッチ付き回転式電子部品として、図８に示すものを開発した。同図に示すようにこの押釦スイッチ付き回転式電子部品は、スライド部材２１０に設けた突起２１１につまみ２３０を回動自在に固定し、スライド部材２１０の表面に取り付けたフレキシブル基板２５０につまみ２３０に取り付けた摺動子２４０を当接し、さらに突起２１１の先端に取り付けたクリック板２６０のクリック部２６９をつまみ２３０に設けたクリック用凹部２３５に係合し、一方スライド部材２１０の外方に設けたバネ収納部２１７内に「く」字状に折り曲げた板バネ２７０を収納して板バネ２７０中央の押圧部２７１を支持板２９０に設けたスイッチ接点２８１上に当接し、同時にその上下両端の係止部２７３，２７５をスライド部材２１０と支持板２９０に固定された押釦用ケース２９５の所定部分に当接して構成されている。
【０００５】
そしてつまみ２３０を回転すると、摺動子２４０がフレキシブル基板２５０に設けたスイッチパターン２５３上を摺動して所望の出力が得られる。一方つまみ２３０を矢印ａ方向に押圧すれば、これと一体にスライド部材２１０もスライド移動して、板バネ２７０がたわめられることで押圧部２７１がスイッチ接点２８１側に突出し、これをオンする。
【０００６】
ところで上記押釦スイッチ付き回転式電子部品は、携帯機器の更なる小型化・薄型化などのため、更なる小型化・薄型化が要求されている。特に板バネ２７０を収納した部分は、その全体が携帯機器の内部に入り込む部分なので、その高さの短縮化が求められている。しかしながら板バネ２７０は「く」字状で比較的長いので、更なる高さ（長さ）の短縮は困難であった。
【０００７】
また上記押釦スイッチ付き回転式電子部品は、スライド部材２１０や固定側部材である支持板２９０や押釦用ケース２９５等の他に、板バネ２７０が必要なので、その部品点数が多く、更なる部品点数の削減と組み立て工程の容易化とが求められていた。
【０００８】
【発明が解決しようとする課題】
本発明は上述の点に鑑みてなされたものでありその目的は、高さ方向（スライド方向）の小型化が図れると共に、部品点数の削減と組み立て工程の容易化が図れる押釦スイッチ付き回転式電子部品を提供することにある。
【０００９】
【課題を解決するための手段】
上記問題点を解決するため本発明にかかる押釦スイッチ付き回転式電子部品は、　　回転式電子部品を取り付けたスライド部材を固定側部材にスライド自在に取り付け、前記スライド部材には弾性変形する揺動部を設け、揺動部には固定側部材に設けたスイッチを押圧する押圧部を設け、一方スライド部材と固定側部材の間には、スライド部材をスライドした際に前記揺動部の押圧部をスイッチ側に揺動させて該スイッチを押圧するようにガイドする揺動ガイド機構を設けたことを特徴とする。
【００１０】
また本発明は、前記揺動部が前記スライド部材のスライド方向に向けて突出して設けられ、一方前記揺動ガイド機構は、揺動部と固定側部材にそれぞれ当接面を設けるとともに、これら両当接面を、スライド部材がスライドした際に当接して揺動部をスイッチ側に揺動させる形状に形成することで構成されていることを特徴とする。
【００１１】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して詳細に説明する。
図１は本発明の一実施形態にかかる押釦スイッチ付き回転式電子部品１を示す概略側断面図である。また図２は押釦スイッチ付き回転式電子部品１の分解斜視図である。両図に示すように押釦スイッチ付き回転式電子部品１は、支持板１０上に、フレキシブル基板２０，３０と、スライド部材５０と、ケース７０と、つまみ８０と、クリック板９０とを取り付けて構成されている。以下各構成部品について説明する。
【００１２】
支持板１０は金属板等の硬質板によって構成され、その上辺中央には下記するスライド部材５０のガイド部５９を上下動自在に係合する凹状のガイド係合部１１が設けられ、またその左右両側辺下部には下記するケース７０の係止部７７，７７を係止する凹状の係止部１３，１３が設けられている。
【００１３】
図３はフレキシブル基板２０，３０を展開して示す展開斜視図である。同図に示すようにフレキシブル基板２０とフレキシブル基板３０は一枚の合成樹脂製シート４１上に形成され、両者は連結部４３によって連結されており、フレキシブル基板２０の方は中央に反転板２１を取り付けることでスイッチＳを形成し、フレキシブル基板３０の方は中央に下記するスライド部材５０の軸支部５５を挿入する開口からなる挿入部３１と、挿入部３１の周囲にリング状に形成されるスイッチパターン３３とを設けて構成されている。フレキシブル基板２０の左右両側辺には下記するケース７０の係止部７７，７７を係合する凹状の係合部２３，２３が設けられている。スイッチＳは反転板２１を押圧した際にフレキシブル基板２０の反転板２１の真下の部分に設けた図示しない複数のスイッチパターン間がオンされる構造に構成されている。なおフレキシブル基板３０のスイッチパターン３３とスイッチＳのスイッチパターンは、何れも図示しない回路パターンによって引出部４３から外部に引き出されている。
【００１４】
図４はスライド部材５０を示す図であり、図４（ａ）は平面図、図４（ｂ）は図４（ａ）のＡ−Ａ断面図である。図４及び図２に示すように、スライド部材５０は合成樹脂を略長方形状の板状に成形して構成されており、その上部は回転式スイッチ形成部５１、下部は押釦スイッチ形成部６１となっている。回転式スイッチ形成部５１は一方の面（図２の手前側の面）に円形のフレキシブル基板載置部５３を設け、フレキシブル基板載置部５３の中央から柱状の軸支部５５を突出し、さらに軸支部５５先端から略小判形の固定部５６を突出し、またフレキシブル基板載置部５３の外周に壁５７を設けて構成されている。回転式スイッチ形成部５１の反対側の面の上部には、前記支持板１０のガイド係合部１１に上下動自在に係合されるＴ字状に突出するガイド部５９が設けられている。押釦スイッチ形成部６１はその面の中にＴ字状に切り欠く切欠部６３を形成することで、切欠部６３の中央に下方向（スライド部材５０のスライド方向）に向かって突出する板状の弾性変形する揺動部６５を設け、また切欠部６３の両肩の部分をストッパ部６９，６９として構成している。揺動部６５の先端辺（下端辺）中央のフレキシブル基板２０側には、球面状に突出する押圧部６７が設けられている。さらに揺動部６５の先端辺（下端辺）のケース７０側の面には、先端に向かってフレキシブル基板２０方向に斜めに傾斜する傾斜面からなる当接面６６が設けられている。
【００１５】
ケース７０は図２に示すように、略矩形状の金属板の左右両辺と下端辺とをスライド部材５０側に折り曲げてスライド部材５０の押釦スイッチ形成部６１を収納する箱形状に形成されている。ケース７０の中央には、周囲を「コ」字状に切り欠いた舌片状の当接部７１が設けられている。当接部７１はその根元部分を中心辺としてスライド部材５０側に所定角度折り曲げられている。当接部７１のスライド部材５０側の面は前記スライド部材５０の揺動部６５に設けた当接面６６に当接する当接面７３（図１参照）となっている。ケース７０の上端辺からはスライド部材５０側に向けて舌片状に二本のストッパ７５，７５が突出し、ケース７０の左右両側辺からはスライド部材５０側に向けて舌片状の係止部７７，７７が突出している。
【００１６】
つまみ８０は合成樹脂を略円板状に成形して構成されており、中央には前記スライド部材５０の軸支部５５を回動自在に挿入する貫通孔からなる軸挿入部８１が設けられ、またクリック板９０側の面の軸挿入部８１の周囲にはリング状に複数の凹状のクリック係合部８３が設けられている。またつまみ８０のスライド部材５０側の面には金属板製の摺動子８５（図１参照）が固定されている。
【００１７】
クリック板９０は略円形の弾性を有する金属板で構成され、中央に前記スライド部材５０の固定部５６を嵌合する形状の挿入部９１を設け、挿入部９１の周囲に二本の円弧状の切り欠き９３，９３を設けることで二本のアーム部９５，９５を設け、各アーム部９５，９５の中央にそれぞれつまみ８０側に湾曲変形するクリック部９７，９７を設けて構成されている。
【００１８】
そしてこの押釦スイッチ付き回転式電子部品１を組み立てるには、まず支持板１０上にフレキシブル基板２０を載置し、その上にスライド部材５０を載置する。そしてスライド部材５０のフレキシブル基板載置部５３上にフレキシブル基板３０を載置する。その際軸支部５５をフレキシブル基板３０の挿入部３１に挿入する。次にスライド部材５０の上からケース７０を被せ、その係止部７７，７７をフレキシブル基板２０の係合部２３，２３と、支持板１０の係止部１３，１３に挿入し、支持板１０の裏面側で折り曲げて上記各部材を一体化する。このときの状態を図５に示す。
【００１９】
そしてスライド部材５０の軸支部５５をつまみ８０の軸挿入部８１に挿入し、さらに軸支部５５先端の固定部５６をクリック板９０の挿入部９１に嵌合し、固定部５６の先端を熱カシメして固定する。図６は以上のようにして組み立てた押釦スイッチ付き回転式電子部品１を反対面側から見た斜視図である。同図に示すようにガイド部５９はガイド係合部１１内に上下動自在に挿入されている。
【００２０】
以上のようにして組み立てられた押釦スイッチ付き回転式電子部品１は、図１に示すように、つまみ８０に取り付けた摺動子８５に設けた接点８７がフレキシブル基板３０に設けたスイッチパターン３３上に当接し、またスライド部材５０の揺動部６５先端の当接面６６とケース７０の当接面７３とが当接し、さらにスライド部材５０の押圧部６７が反転板２１上に当接している。さらにこのとき図５に示すように、ケース７０のストッパ７５，７５がスライド部材５０のストッパ部６９，６９に当接することで、当接面６６と当接面７３とが当接している位置よりもスライド部材５０が上方向に移動しないようにしてガタが生じるのを防止している。
【００２１】
そして図１において、つまみ８０を回転すれば、つまみ８０と一体に摺動子８５が回転してその接点８７がスイッチパターン３３上を摺動し、その電気的出力が変化する。同時にクリック板９０のクリック部９７，９７がつまみ８０のクリック係合部８３に係合離脱することでクリック感覚が生じる。
【００２２】
一方つまみ８０を半径方向（図１の矢印Ｙ方向（スライド方向））に押圧すれば、つまみ８０等と共にスライド部材５０が下降し、図７に示すように揺動部６５が弾性変形するため揺動部６５の当接面６６がケース７０の当接面７３上を摺動していくことで揺動部６５がスイッチＳ方向に揺動して行き、この結果押圧部６７が反転板２１を押圧して反転し、スイッチＳをオンする。つまみ８０への押圧を解除すると、反転板２１の弾性復元力によって反転板２１やスライド部材５０は元の位置に自動復帰してスイッチＳがオフする。つまり本実施形態においては、スライド部材５０と固定側部材であるケース７０との間に、スライド部材５０をスライドした際に揺動部６５の押圧部６７をスイッチＳ方向に揺動させてこのスイッチＳを押圧してオンするようにガイドする揺動ガイド機構を、揺動部６５に設けた当接面６６とケース７０に設けた当接面７３とによって構成している。
【００２３】
以上本発明の実施形態を説明したが、本発明は上記実施形態に限定されるものではなく、特許請求の範囲、及び明細書と図面に記載された技術的思想の範囲内において種々の変形が可能である。なお直接明細書及び図面に記載がない何れの形状や構造や材質であっても、本願発明の作用・効果を奏する以上、本願発明の技術的思想の範囲内である。
【００２４】
例えば上記実施形態ではスライド部材５０に回転式スイッチを取り付けた例を示したが、回転式可変抵抗器等、他の回転式電子部品を取り付けても良い。回転式電子部品の構造も上記実施形態に限定されず、要はスライド部材５０に取り付けることができる回転式電子部品であればどのような構造のものであっても良い。また上記実施形態では反転板２１を取り付けたが、反転板２１は必ずしも必要なく、スイッチが構成できるものであればどのような構造のスイッチであっても良い。
【００２５】
また上記実施形態では、揺動ガイド機構を、揺動部６５に設けた当接面６６とケース７０に設けた当接面７３とによって構成しているが、本発明にかかる揺動ガイド機構は、この構造に限定されるものではない。例えば両当接面６６，７３の内の何れか一方のみに傾斜面を設けても揺動部６５をスイッチＳ方向に揺動させることができる。また当接面６６や当接面７３は必ずしも平面状の傾斜面でなくても良く、円弧状であってもその他の形状であっても良い。要は両当接面を、スライド部材がスライドした際に当接して揺動部をスイッチ方向に揺動させる形状とするものであれば、どのような形状・構造であってもよい。さらに言えば揺動ガイド機構は、スライド部材５０をスライドした際に揺動部６５の押圧部６７をスイッチＳ方向に揺動させてこのスイッチＳをオンする構造であれば、どのような構造の揺動ガイド機構であっても良い。
【００２６】
また上記実施形態ではスライド部材５０のスライド方向に平行な面上にスイッチＳを設けたが、スイッチＳは、スライド部材５０のスライド方向に対して傾斜する面上に設けても良い。
【００２７】
【発明の効果】
以上詳細に説明したように本発明によれば、スライド部材に設けた揺動部を揺動することで、固定側部材に設けたスイッチをオンオフするように構成したので、高さ方向（スライド方向）の小型化が図れるばかりか、部品点数の削減と組み立て工程の容易化が図れる。
