【００３３】
以下、本発明の実施の形態について、図１〜図１０を用いて説明する。
【００３４】
（実施の形態１）
図１および図２は、本発明の実施の形態１による充電器の外観図およびそのＡ−Ａ線上の断面図である。この充電器１は後述する電子機器を収納する開口部を備えた穴状の開口部１１を有し、開口部１１の底面１２には一対の充電端子１３ａ，１３ｂが図の縦方向に隣接して配置された構成となっている。
【００３５】
また、充電端子１３ａ，１３ｂが配置された延長線上（Ａ−Ａ線上）の開口部１１の両側面には、開口部１１の内側に向けて突出した互いに高さの異なるリブ１４ａ，１４ｂが形成され、リブ１４ａ，１４ｂの上方には開口部１１の外側に向けて溝１５ａ，１５ｂが穿設されている。
【００３６】
また、充電端子１３ａ，１３ｂは開口部１１の下面に設けた端子ホルダ１６にコイルスプリング１７ａ，１７ｂを介して取り付けられており、コイルスプリング１７ａ，１７ｂの弾性によって上下方向に摺動する構成となっている。
【００３７】
また、充電端子１３ａ，１３ｂは開口部１１に挿入される電子機器のバッテリー端子に接触する位置に、底面１２の内側から突出して取り付けられている。なお、充電端子１３ａ，１３ｂは図示せぬリード線を介して充電器１内の充電回路に接続されている。
【００３８】
図３は、前述した充電器１の開口部１１に挿入されて充電される携帯電話機等の電子機器２の実施の形態１を示す外観図である。同図において、図（ａ）は正面図、図（ｂ）は左側面図、図（ｃ）は右側面図、図（ｄ）は底面図である。
【００３９】
この電子機器２は外ケース３に収納され、内部に充電式電池が内蔵された電池パック４が装着されている。外ケース３は天然、合成皮革、布等の可撓性シート材または軟質の合成樹脂シート材等を縫製したものや、合成樹脂を成形したものなどからなり、電子機器２を着脱自在に収納できる構成となっている。
【００４０】
電子機器２の底面には一対のバッテリー端子２１ａ，２１ｂが設けられ、外ケース３の底面３１には、このバッテリー端子２１ａ，２１ｂを表出させるための端子用孔３２ａ，３２ｂが設けられている。
【００４１】
また、電子機器２の側面下部には、電子機器２が充電器１の開口部１１に収納されるときに、溝１５ａ，１５ｂに挿入されてガイドされる突起２２ａ，２２ｂと、リブ１４ａ，１４ｂに嵌合する互いに高さの異なる溝２３ａ，２３ｂとが設けられている。
【００４２】
また、外ケース３の側面下部には切欠部３３ａ，３３ｂが設けられている。これによって電子機器２の側面下部が表出され、電子機器２の側面下部に設置された突起２２ａ，２２ｂおよび溝２３ａ，２３ｂが外部に表出するように構成されている。
【００４３】
次に、充電器１に電子機器２を挿入する際の動作について、図４および図５に示す断面図およびその要部断面図を参照しながら説明する。
【００４４】
まず、外ケース３に収納された電子機器２が充電器１の開口部１１に底面側から挿入されると、電子機器２の突起２２ａ，２２ｂが開口部１１の溝１５ａ，１５ｂに挿入されてガイドされ、さらに溝２３ａ，２３ｂにリブ１４ａ，１４ｂが挿入されてガイドされる。外ケース３に収納されていない電子機器２についても同様にして挿入される。
【００４５】
これによって充電器１の充電端子１３ａ，１３ｂが電子機器２のバッテリー端子２１ａ，２１ｂと接触し、電池パック４に内蔵されている充電式電池が充電器１に内蔵されている充電回路によって充電されることになる。
【００４６】
また、バッテリー端子２１ａ，２１ｂと端子用孔３２ａ，３２ｂとがずれた状態で電子機器２が外ケース３に収納され、その状態で電子機器２が充電器１の開口部１１に挿入された場合は、図５に示すように、リブ１４ａ，１４ｂが外ケース３の底面３１に当たり、この底面３１を内側を押して端子用孔３２ａ，３２ｂの位置を矯正し、端子用孔３２ａ，３２ｂがバッテリー端子２１ａ，２１ｂを表出するように移動させる。これによって充電端子１３ａ，１３ｂとバッテリー端子２１ａ，２１ｂとが接触できることになる。
【００４７】
このように、充電器１の開口部１１の両側面に溝１５ａ，１５ｂを設け、電子機器２の両側面に突起２２ａ，２２ｂを設け、外ケース３に突起２２ａ，２２ｂを表出させる切り欠き３３ａ，３３ｂを設けることによって、外ケース３の有無にかかわらず充電器１の開口部１１に電子機器２を挿入する際の嵌合の位置決めを溝１５ａ，１５ｂと突起２２ａ，２２ｂとですることができる。
【００４８】
なお、充電端子１３ａ，１３ｂに代えて電磁誘導を利用した無接点充電機能を備えた充電電圧供給部を設け、バッテリー端子２１ａ，２１ｂに代えて同様の充電電圧受給部を設けるようにしてもよい。なお、充電端子１３ａ，１３ｂも広義の充電電圧供給部であり、バッテリー端子２１ａ，２１ｂも広義の充電電圧受給部である。以下の実施の形態においても同様である。
【００４９】
（実施の形態２）
図６は、本発明の実施の形態２による電子機器２を示す外観図で、図（ａ）は正面図、図（ｂ）は左側面図、図（ｃ）は右側面図、図（ｄ）は底面図を示している。この電子機器２は着脱自在に装着された電池パック４の底面にバッテリー端子４１ａ，４１ｂを設け、電池パック４の両側面に突起４２ａ，４２ｂと、溝４３ａ，４３ｂとを設けたものである。
【００５０】
すなわち、本実施の形態による電子機器２は、前述の実施の形態が電子機器２の本体の底面にバッテリー端子２１ａ，２１ｂを設け、側面に突起２２ａ，２２ｂおよび溝２３ａ，２３ｂを設けたのに対し、本体に着脱自在に装着される電池パック４にバッテリー端子４１ａ，４１ｂ、突起４２ａ，４２ｂ、溝４３ａ，４３ｂを設けたものである。
【００５１】
従って、前述の実施の形態と同様に電池パック４を装着した電子機器２を充電器１に挿入することができるほかに、電子機器２から電池パック４を取り外し、電池パック４単体で充電器１に挿入することができる。
【００５２】
次に、充電器１に電池パック４単体を挿入する際の動作について、図７および図８に示す断面図を参照しながら説明する。
【００５３】
図７は、電池パック４を充電器１の開口部１１に正規の方向で挿入した場合の状態を示す断面図である。この実施の形態のように電池パック４に突起４２ａ，４２ｂを設けてあるので、突起４２ａ，４２ｂが開口部１１の溝１５ａ，１５ｂに挿入されてガイドされ、さらに溝４３ａ，４３ｂにリブ１４ａ，１４ｂが挿入されてガイドされる。
【００５４】
これによって充電器１の充電端子１３ａ，１３ｂが電池パック４のバッテリー端子４１ａ，４１ｂと接触し、充電器１に内蔵されている充電回路によって電池パック４に内蔵されている充電式電池が充電されることになる。
【００５５】
また、図８に示すように、電池パック４を表裏反対に挿入した場合は、開口部１１に設けた高さの高いリブ１４ｂが電池パック４に設けた長さの短い溝４３ｂに挿入されるので、これがスットッパーの役割を果し、電池パック４が途中で止まり挿入されなくなる。
【００５６】
このように、電池パック４に突起４２ａ，４２ｂを設けることにより、電池パック４単体を開口部１１にセットすることができる。また、電池パック４を逆に挿入しようとした場合は、開口部１１に設けた高さの異なるリブ１４ａ，１４ｂにより電池パック４が途中で止まり挿入されなくなるため、利用者に逆挿入を知らせることができる。
【００５７】
（実施の形態３）
図９は、本発明の実施の形態３による充電器１を示す外観図で、充電端子１３ａ，１３ｂを開口部１１の低側面に設置した実施の形態を示すもので、その他の構成は前述の実施の形態１と同一の構成を有している。
【００５８】
また、図１０は、本発明の実施の形態３による電子機器２を示す外観図で、バッテリー端子２１ａ，２１ｂを電子機器２の底面端部に設置し、同じ位置に外ケース３の端子用孔３２ａ，３２ｂを設置した実施の形態を示すもので、その他の構成は前述の実施の形態１と同一の構成を有している。
【００５９】
本実施の形態においても、電子機器２が充電器１の開口部１１に底面側から挿入されると、電子機器２の突起２２ａ，２２ｂが開口部１１の溝１５ａ，１５ｂに挿入されてガイドされ、さらに溝２３ａ，２３ｂにリブ１４ａ，１４ｂが挿入されてガイドされる。
【００６０】
これによって充電器１の充電端子１３ａ，１３ｂが電子機器２のバッテリー端子２１ａ，２１ｂと接触し、電池パック４に内蔵されている充電式電池が充電器１に内蔵されている充電回路によって充電されることになる。
【００６１】
【発明の効果】
本発明の充電システムによると、充電器の開口部の両側面に溝を設け、電子機器の両側面に突起を設けることによって、充電器の開口部に電子機器を挿入するときの嵌合の位置決めを溝と突起とで行い、簡易な構成で充電電圧供給部から充電電圧受給部を介して電子機器内部の電池を充電することができるという有利な効果が得られる。
【００６５】
本発明の充電システムによると、充電器に設けた溝およびリブと、電子機器または電池パックに設けた突起および溝とによって、電子機器または電池パックを充電器に挿入する際の位置決めを行うことができ、電子機器または電池パックを表裏逆に挿入しようとした場合は、開口部に設けた高さの異なるリブと電子機器または電池パックの溝とが合わないため途中で止まり、逆挿入を防止することができるという有利な効果が得られる。
【００６７】
また、本発明の充電器によると、開口部に設けた溝およびリブと、電子機器または電池パックに設けた突起および溝とによって、電子機器または電池パックを開口部に挿入する際の位置決めを行うことができ、電子機器または電池パックを表裏逆に挿入すると、高さの異なるリブと長さの異なる溝とが合わないため途中で止まり、逆挿入を防止できるという有利な効果が得られる。
【００６９】
本発明の電子機器によると、両側面に設けた突起および溝を開口部の両側面に設けた溝およびリブと嵌合することによって、開口部に挿入するときの位置決めを行うことができ、また表裏逆に挿入すると、高さの異なるリブと長さの異なる溝とが合わないため途中で止まり、逆挿入を防止することができるという有利な効果が得られる。
【００７２】
本発明の電池パックによると、両側面に設けた突起および溝を開口部の両側面に設けた溝およびリブと嵌合することによって、開口部に挿入するときの位置決めを行うことができ、表裏逆に挿入すると、高さの異なるリブと長さの異なる溝とが合わないため途中で止まり、逆挿入を防止することができるという有利な効果が得られる。
