Description

【０００１】
【発明の属する技術分野】
本発明は、操作釦を着脱自在に保持する操作釦装置および操作釦装置を備えた電子機器に関するものである。
【０００２】
【従来の技術】
従来から、この種の操作釦装置は、ＤＶＤ（Ｄｉｇｉｔａｌ　Ｖｅｒｓａｔｉｌｅ　Ｄｉｓｃ）プレーヤ、ＣＤ（Ｃｏｍｐａｃｔ　Ｄｉｓｃ）プレーヤ、カセットテーププレーヤ、ラジオ受信機などが組み込まれた電子機器を操作する操作釦装置として普及している。
【０００３】
このような従来の操作釦装置３００は、図６から図８に示すように、貫通孔３１１が形成された保持部３１２と保持部３１２の一端３１２ａと他端３１２ｂとの間の内周面３１３から突出する２つの突出部３１５、３１６とを有する枠体３１０と、枠体３１０の貫通孔３１１に挿入された側部３２１と側部３２１の一端３２１ａと他端３２１ｂとの間に設けられ枠体３１０の突出部３１５、３１６に係合する２つの係合部３２５、３２６と側部３２１の他端３２１ｂに接続された頂部３２４とを有し枠体３１０の保持部３１２に着脱自在に保持された操作釦３２０とを備えている。
【０００４】
また、従来の操作釦装置３００は、操作釦３２０の側部３２１の一端３２１ａ側に配設された回路基板３４５を備えており、この回路基板３４５上には、操作釦３２０の頂部３２４に光を照射する光源３４０および操作釦３２０の側部３２１の一端３２１ａに対向する図示しないスイッチが設けられている。
【０００５】
枠体３１０の突出部３１５、３１６は、枠体３１０の保持部３１２の内周面３１３に直行する直行面３１５ａ、３１６ａを有しており、操作釦３２０の係合部３２５、３２６は、枠体３１０の突出部３１５、３１６の直行面３１５ａ、３１６ａに対して平行に設けられた当接面３２５ａ、３２６ａを有している。操作釦３２０の係合部３２５、３２６の当接面３２５ａ、３２６ａは、操作釦３２０が回路基盤１４５から遠ざかる方向、即ち、操作釦３２０の取り外し方向に移動することにより、枠体３１０の突出部３１５、３１６の直行面３１５ａ、３１６ａに当接するようになっている。
【０００６】
【発明が解決しようとする課題】
しかしながら、上記従来の操作釦装置においては、作業者が、ピンセットなどの工具を用いて操作釦３２０の側部３２１の一端３２１ａを操作釦３２０の中心方向に押圧し、操作釦３２０の側部３２１を操作釦３２０の中心方向に弾性変形させ、操作釦３２０の係合部３２５、３２６を枠体３１０の突出部３１５、３１６から離隔させた状態で、操作釦３２０を枠体３１０の保持部３１２から取り外すようになっているため、操作釦３２０を容易に取り外すことができないという問題があった。
【０００７】
そこで、本発明は、このような問題を解決するため、操作釦を容易に取り外すことができる操作釦装置を提供することを目的とする。
【０００８】
【課題を解決するための手段】
上記の課題を解決するために、本発明の操作釦装置は、貫通孔が形成された保持部と前記保持部の一端と他端との間の内周面から突出する突出部と前記保持部の一端から内周面に沿って設けられた一端ガイド部とを有する枠体と、前記貫通孔に挿入された側部と前記側部の一端と他端との間に設けられ前記突出部に係合する係合部と前記側部の一端の外周面から突出する凸部とを有し前記保持部に着脱自在に保持された操作釦とを備え、前記操作釦は、前記保持部から取り外されるときに、前記凸部が前記一端ガイド部に当接して前記操作釦の中心方向に押圧され、前記側部が前記操作釦の中心方向に弾性変形する構成を有している。
【０００９】
この構成により、本発明の操作釦装置は、操作釦の取り外し方向への移動に伴って、操作釦の凸部が枠体の一端ガイド部に押圧され、操作釦の側部が操作釦の中心方向に弾性変形するので、操作釦を容易に取り外すことができる。
【００１０】
また、本発明の操作釦装置は、前記突出部は、前記保持部の他端側に傾斜する傾斜面を有し、前記係合部は、前記傾斜面に対して平行に設けられた当接面を有し、前記操作釦は、前記保持部から取り外されるときに、前記当接面が前記傾斜面に当接して前記操作釦の中心方向に押圧され、前記側部が前記操作釦の中心方向に弾性変形する構成を有している。
【００１１】
この構成により、本発明の操作釦装置は、操作釦の取り外し方向への移動に伴って、操作釦の係合部の当接面が枠体の突出部の傾斜面に押圧され、操作釦の側部が操作釦の中心方向に弾性変形するので、操作釦を容易に取り外すことができる。
【００１２】
また、本発明の操作釦装置は、前記凸部は、前記側部の外周面からの前記凸部の突出長さが、前記保持部の内周面からの前記突出部の突出長さよりも大きくなるように設けられた構成を有している。
【００１３】
この構成により、本発明の操作釦装置は、操作釦の凸部が枠体の一端ガイド部に押圧された状態で、操作釦の係合部が枠体の突出部から離隔するので、操作釦を容易に取り外すことができる。
【００１４】
また、本発明の操作釦装置は、前記突出部は、前記側部の外周面に一対に設けられた前記凸部の軌跡の間に配置された構成を有している。
【００１５】
この構成により、本発明の操作釦装置は、操作釦の凸部が枠体の一端ガイド部に２点で当接するので、操作釦の側部を枠体の突出部に対して平行に弾性変形させることができ、操作釦を容易に取り外すことができる。
【００１６】
また、本発明の操作釦装置は、前記枠体は、前記保持部の他端から内周面に沿って設けられた他端ガイド部を有し、前記操作釦は、前記保持部に取り付けられるときに、前記凸部が前記他端ガイド部に当接して前記操作釦の中心方向に押圧され、前記側部が前記操作釦の中心方向に弾性変形する構成を有している。
【００１７】
この構成により、本発明の操作釦装置は、操作釦の取り付け方向への移動に伴って、操作釦の凸部が枠体の他端ガイド部に押圧され、操作釦の側部が操作釦の中心方向に弾性変形するので、操作釦を容易に取り付けることができる。
【００１８】
また、本発明の操作釦装置は、前記凸部および前記凸部に当接する前記他端ガイド部は、前記操作釦毎に異なる位置に設けられた構成を有している。
【００１９】
この構成により、本発明の操作釦装置は、各操作釦が枠体の所定の保持部に対応しているので、操作釦の取り付け間違いを防止することができる。
【００２０】
また、本発明の電子機器は、操作釦装置を備えた構成を有している。
【００２１】
この構成により、本発明の電子機器は、操作釦の取り外し方向への移動に伴って、操作釦の凸部が枠体の一端ガイド部に押圧され、操作釦の側部が操作釦の中心方向に弾性変形するので、操作釦を容易に取り外すことができる。
【００２２】
【発明の実施の形態】
以下、本発明の一実施の形態について、図面を用いて説明する。
【００２３】
図１から図５は、本実施の形態に係る操作釦装置および電子機器を示す図である。
【００２４】
図５において、電子機器２００は、ＤＶＤプレーヤ、ＣＤプレーヤ、カセットテーププレーヤ、ラジオ受信機などが組み込まれたものであり、この電子機器２００の前面には、電子機器２００の各種機能を操作する操作釦装置１００が設けられている。操作釦装置１００は、電子機器２００の筐体に取り付けられた枠体１１０と、文字、記号などが形成された複数の操作釦１２０とを備えている。以下、１つの操作釦１２０とその周辺の部材に注目して操作釦装置１００の構成を説明する。
【００２５】
図１から図４において、枠体１１０は、貫通孔１１１が形成された保持部１１２と、保持部１１２の一端１１２ａと他端１１２ｂとの間の内周面１１３から突出する２つの突出部１１５、１１６と、保持部１１２の一端１１２ａから内周面１１３に沿って設けられた２対の一端ガイド部１１７ａ、１１７ｂ、１１８ａ、１１８ｂとを有している。
【００２６】
枠体１１０の突出部１１５、１１６は、操作釦１２０の中心軸に対して両側に配置されており、枠体１１０の保持部１１２の内周面１１３に直行する方向に突出している。枠体１１０の一端ガイド部１１７ａ、１１７ｂ、１１８ａ、１１８ｂは、操作釦１２０の中心軸に対して平行な方向に延在しており、枠体１１０の保持部１１２の内周面１１３に形成された２対の溝によって構成されている。
【００２７】
操作釦１２０は、枠体１１０の貫通孔１１１に挿入された側部１２１と、側部１２１の一端１２１ａと他端１２１ｂとの間に設けられ枠体１１０の突出部１１５、１１６に係合する２つの係合部１２５、１２６と、側部１２１の一端１２１ａの外周面１２２から突出する２対の凸部１２７ａ、１２７ｂ、１２８ａ、１２８ｂと、側部１２１の他端１２１ｂに接続された頂部１２４とを有しており、枠体１１０の保持部１１２に着脱自在に保持されている。
【００２８】
操作釦１２０の係合部１２５、１２６は、操作釦１２０の中心軸に対して両側に配置されており、操作釦１２０の側部１２１の外周面１２２に形成された２つの開口によって構成されている。操作釦１２０の凸部１２７ａ、１２７ｂ、１２８ａ、１２８ｂは、操作釦１２０の側部１２１の外周面１２２に直行する方向に突出している。
【００２９】
枠体１１０の突出部１１５は、操作釦１２０の側部１２１の外周面１２２に一対に設けられた凸部１２７ａ、凸部１２７ｂの軌跡の間に配置されている。また、枠体１１０の突出部１１６は、操作釦１２０の側部１２１の外周面１２２に一対に設けられた凸部１２８ａ、凸部１２８ｂの軌跡の間に配置されている。
【００３０】
また、操作釦装置１００は、操作釦１２０の側部１２１の一端１２１ａ側に配設された回路基板１４５を備えており、この回路基板１４５上には、操作釦１２０の頂部１２４に光を照射する光源１４０および操作釦１２０の側部１２１の一端１２１ａに対向する図示しないスイッチが設けられている。操作釦１２０は、回路基板１４５から遠ざかる方向、即ち、操作釦１２０の取り外し方向と、回路基板１４５に近づく方向、即ち、操作釦１２０の取り付け方向とに移動するようになっている。
【００３１】
操作釦１２０は、枠体１１０の保持部１１２から取り外されるときに、操作釦１２０の凸部１２７ａ、１２７ｂ、１２８ａ、１２８ｂが枠体１１０の一端ガイド部１１７ａ、１１７ｂ、１１８ａ、１１８ｂに当接して操作釦１２０の中心方向に押圧され、操作釦１２０の側部１２１が操作釦１２０の中心方向に弾性変形するように設けられている。
【００３２】
枠体１１０の突出部１１５、１１６は、枠体１１０の保持部１１２の他端１１２ｂ側に傾斜する傾斜面１１５ａ、１１６ａを有しており、操作釦１２０の係合部１２５、１２６は、枠体１１０の突出部１１５、１１６の傾斜面１１５ａ、１１６ａに対して平行に設けられた当接面１２５ａ、１２６ａを有している。操作釦１２０の係合部１２５、１２６の当接面１２５ａ、１２６ａは、操作釦１２０が取り外し方向に移動することにより、枠体１１０の突出部１１５、１１６の傾斜面１１５ａ、１１６ａに当接するようになっている。
【００３３】
操作釦１２０は、枠体１１０の保持部１１２から取り外されるときに、操作釦１２０の係合部１２５、１２６の当接面１２５ａ、１２６ａが枠体１１０の突出部１１５、１１６の傾斜面１１５ａ、１１６ａに当接して操作釦１２０の中心方向に押圧され、操作釦１２０の側部１２１が操作釦１２０の中心方向に弾性変形するように設けられている。
【００３４】
したがって、操作釦１２０は、操作釦１２０が取り外し方向に移動することにより、操作釦１２０の凸部１２７ａ、１２７ｂ、１２８ａ、１２８ｂが操作釦１２０の中心方向に押圧されて操作釦１２０の側部１２１が操作釦１２０の中心方向に弾性変形し、操作釦１２０の係合部１２５、１２６の当接面１２５ａ、１２６ａが操作釦１２０の中心方向に押圧されて操作釦１２０の側部１２１が操作釦１２０の中心方向に弾性変形し、操作釦１２０の係合部１２５、１２６が枠体１１０の突出部１１５、１１６から離隔して枠体１１０の保持部１１２から取り外されるようになっている。
【００３５】
枠体１１０は、枠体１１０の保持部１１２の他端１１２ａから内周面１１３に沿って設けられた他端ガイド部１３７ａ、１３７ｂ、１３８ａ、１３８ｂを有している。
【００３６】
操作釦１２０は、枠体１１０の保持部１１２に取り付けられるときに、操作釦１２０の凸部１２７ａ、１２７ｂ、１２８ａ、１２８ｂが枠体１１０の他端ガイド部１３７ａ、１３７ｂ、１３８ａ、１３８ｂに当接して操作釦１２０の中心方向に押圧され、操作釦１２０の側部１２１が操作釦１２０の中心方向に弾性変形するように設けられている。
【００３７】
したがって、操作釦１２０は、操作釦１２０が取り付け方向に移動することにより、操作釦１２０の凸部１２７ａ、１２７ｂ、１２８ａ、１２８ｂが操作釦１２０の中心方向に押圧されて操作釦１２０の側部１２１が操作釦１２０の中心方向に弾性変形し、操作釦１２０の係合部１２５、１２６が枠体１１０の突出部１１５、１１６から離隔した状態で操作釦１２０の取り付け方向に移動し、操作釦１２０の係合部１２５、１２６が枠体１１０の突出部１１５、１１６に係合して枠体１１０の保持部１１２に取り付けられるようになっている。
【００３８】
操作釦１２０の凸部１２７ａ、１２７ｂ、１２８ａ、１２８ｂおよび操作釦１２０の凸部１２７ａ、１２７ｂ、１２８ａ、１２８ｂに当接する枠体１１０の他端ガイド部１３７ａ、１３７ｂ、１３８ａ、１３８ｂは、操作釦毎に異なる位置に設けられている。
【００３９】
以上説明したように、本実施の形態では、操作釦１２０の取り外し方向への移動に伴って、操作釦１２０の凸部１２７ａ、１２７ｂ、１２８ａ、１２８ｂが枠体１１０の一端ガイド部１１７ａ、１１７ｂ、１１８ａ、１１８ｂに押圧され、操作釦１２０の側部１２１が操作釦１２０の中心方向に弾性変形するので、操作釦１２０を容易に取り外すことができる。
【００４０】
また、本実施の形態では、操作釦１２０の取り外し方向への移動に伴って、操作釦１２０の係合部１２５、１２６の当接面１２５ａ、１２６ａが枠体１１０の突出部１１５、１１６の傾斜面１１５ａ、１１６ａに押圧され、操作釦１２０の側部１２１が操作釦１２０の中心方向に弾性変形するので、操作釦１２０を容易に取り外すことができる。
【００４１】
また、本実施の形態では、操作釦１２０の凸部１２７ａ、１２７ｂが枠体１１０の一端ガイド部１１７ａ、１１７ｂに２点で当接するとともに、操作釦１２０の凸部１２８ａ、１２８ｂが枠体１１０の一端ガイド部１１８ａ、１１８ｂに２点で当接するので、操作釦１２０の側部１２１を枠体１１０の突出部１１５、１１６に対して平行に弾性変形させることができ、操作釦１２０を容易に取り外すことができる。
【００４２】
また、本実施の形態では、操作釦１２０の取り付け方向への移動に伴って、操作釦１２０の凸部１２７ａ、１２７ｂ、１２８ａ、１２８ｂが枠体１１０の他端ガイド部１３７ａ、１３７ｂ、１３８ａ、１３８ｂに押圧され、操作釦１２０の側部１２１が操作釦１２０の中心方向に弾性変形するので、操作釦１２０を容易に取り付けることができる。
【００４３】
また、本実施の形態では、操作釦１２０の凸部１２７ａ、１２７ｂ、１２８ａ、１２８ｂおよび枠体１１０の他端ガイド部１３７ａ、１３７ｂ、１３８ａ、１３８ｂが操作釦毎に異なる位置に設けられており、各操作釦１２０が枠体１１０の所定の保持部１１２に対応しているので、操作釦１２０の取り付け間違いを防止することができる。
【００４４】
なお、本実施の形態において、操作釦１２０の凸部１２７ａ、１２７ｂ、１２８ａ、１２８ｂは、操作釦１２０の側部１２１の外周面１２２からの凸部１２７ａ、１２７ｂ、１２８ａ、１２８ｂの突出長さが、枠体１１０の保持部１１２の内周面１１３からの突出部１１５、１１６の突出長さよりも大きくなるように設けられてもよく、このように構成された場合には、操作釦１２０の凸部１２７ａ、１２７ｂ、１２８ａ、１２８ｂが枠体１１０の一端ガイド部１１７ａ、１１７ｂ、１１８ａ、１１８ｂに押圧された状態で、操作釦１２０の係合部１２５、１２６が枠体１１０の突出部１１５、１１６から離隔するので、操作釦１２０を容易に取り外すことができる。
【００４５】
