Description

【０００１】
【発明の属する技術分野】
本発明は、電極構造の異なる複数種類の電池を選択的に収容するための電池収容装置及びその電池収容装置を設けた電子機器に関する。
【０００２】
【従来の技術】
従来より、例えばヘッドホンステレオやビデオカメラ装置等のように、携帯型の各種電子機器においては、電源電池を収容するための電池収容部が設けられている。
また、このような電子機器に用いられる電源電池としては、各種のものが用いられている。例えば単３型乾電池は、どこでも入手が容易であり、手軽に電池交換を行える便利さがある。一方、角型２次電池は、専用の充電器を用いることにより、繰り返し充電して使用できる利点がある。
【０００３】
そして、このような単３型乾電池と角型２次電池とを共通の電池収容部に選択的に直接装着できるようにし、専用のアダプタを交換することなく２種類の電池を併用できるものも提供されている（例えば特開平８−１６２０８０号公報、特開平９−２８９００４号公報、特開平７−２２０１０号公報、特開平５−５４６２３号公報参照）。
【０００４】
【発明が解決しようとする課題】
しかしながら、上述した従来技術では、外周形状の異なる複数種類の電池を装着するために、それぞれ個別に部品が必要であったり、特別な操作が必要であり、構成が複雑化するとともに、電池交換時の作業性が悪いという問題がある。
【０００５】
そこで本発明の目的は、外周形状の異なる複数種類の電池に対して共通の構造で対応でき、かつ、特別な操作を行うことなく複数種類の電池交換を容易に行うことができる電池収容装置及びその電池収容装置を設けた電子機器を提供することにある。
【０００６】
【課題を解決するための手段】
本発明は、前記目的を達成するため、互いに電極位置の異なる角型２次電池と２つの円柱型電池とを選択的に収容する電池収容装置において、角型２次電池及び２つの円柱型電池を電極軸方向に挿入する挿入口を有するとともに、角型２次電池の外周形状に略々対応する内周形状を有する収容ボックス部と、収容ボックス部の挿入口を閉蓋するとともに、内面に電極部を備えた電池蓋と、収容ボックス部の電池蓋と対向する内壁部に設けられた電極板と、各電池の挿入方向と略直交する平面上で、収容ボックス部の第１の内壁面とこの第１の内壁面に臨む２つの円柱型電池の外周面との間に形成される間隙部に略々対応する形状を有する１つまたは複数の仕切り部材と、仕切り部材を、収容ボックス部の第１の内壁面より略直立した状態から収容ボックス部の第１の内壁面に沿って折り畳んだ状態まで回転可能に支持する支持機構と、支持機構によって支持された仕切り部材を収容ボックス部の第１の内壁面より略直立した状態となる方向に付勢する付勢部材とを有し、角型２次電池を収容ボックス部に挿入する際は、その角型２次電池により仕切り部材を収容ボックス部の第１の内壁面に沿って折り畳んだ状態とし、２つの円柱型電池を収容ボックス部に挿入する際は、前記付勢部材により収容ボックス部の第１の内壁面に対して略直立した状態に変位する仕切り部材で円柱電池を所定の位置に移動させ、２つの円柱型電池を互いに離間して配置することを特徴とする。
また、本発明の電子機器は、機器本体と、機器本体に設けられるとともに互いに電極位置の異なる角型２次電池と２つの円柱型電池とを選択的に収容する電池収容装置と、を備え、電池収容装置は、角型２次電池及び２つの円柱型電池を電極軸方向に挿入する挿入口を有するとともに、角型２次電池の外周形状に略々対応する内周形状を有する収容ボックス部と、収容ボックス部の挿入口を閉蓋するとともに、内面に電極部を備えた電池蓋と、収容ボックス部の電池蓋と対向する内壁部に設けられた電極板と、各電池の挿入方向と略直交する平面上で、収容ボックス部の第１の内壁面とこの第１の内壁面に臨む２つの円柱型電池の外周面との間に形成される間隙部に略々対応する形状を有する１つまたは複数の仕切り部材と、仕切り部材を、収容ボックス部の第１の内壁面より略直立した状態から収容ボックス部の第１の内壁面に沿って折り畳んだ状態まで回転可能に支持する支持機構と、支持機構によって支持された仕切り部材を収容ボックス部の第１の内壁面より略直立した状態となる方向に付勢する付勢部材とを有し、角型２次電池を収容ボックス部に挿入する際は、その角型２次電池により仕切り部材を収容ボックス部の第１の内壁面に沿って折り畳んだ状態とし、２つの円柱型電池を収容ボックス部に挿入する際は、前記付勢部材により収容ボックス部の第１の内壁面に対して略直立した状態に変位する仕切り部材で円柱電池を所定の位置に移動させ、２つの円柱型電池を互いに離間して配置することを特徴とする。
【０００７】
本発明の電池収容装置及び電子機器では、角型２次電池を収容ボックス部に挿入すると、仕切り部材は、角型２次電池の先端部に押され、付勢部材の力に抗して支持機構を介して回転し、収容ボックス部の内周面に沿って折り畳んだ状態となる。
これにより、角型２次電池全体が収容ボックス部に収容でき、また、角型２次電池の電極部が収容ボックス部内の第１の電極部に接触する。この状態で、収容ボックス部を電池蓋で閉蓋し、角型２次電池を収容ボックス部内部に位置決め配置できる。
また、角型２次電池を収容ボックス部より抜き取る場合には、電池蓋を開放することにより、容易に抜き取ることができる。この際、折り畳まれた仕切り部材が付勢部材の力によって復帰することにより、角型２次電池を押し出す方向に作用し、スムーズに抜き取ることができる。
【０００８】
また、２つの円柱型電池を収容ボックス部に挿入すると、仕切り部材が２つの円柱型電池の外周形状に対応する形状を有するため、２つの円柱型電池は仕切り部材を避ける状態で収容ボックス部に挿入される。
これにより、仕切り部材は収容ボックス部の内周面より略直立した状態で保持され、２つの円柱型電池が収容ボックス部内で仕切り部材によって位置決めされ、ガタ付きなく収容できる。
そして、２つの円柱型電池全体を収容ボックス部に収容することで、２つの円柱型電池の電極部が収容ボックス部内の第２の電極部に接触する。そして、電池蓋を閉蓋し、２つの円柱型電池を収容ボックス部内部に位置決め配置する。
したがって、外径の異なる角型２次電池と２つの円柱型電池に対し、共通の構造で安定した収納装置を得ることができ、特別な操作を行うことなく、電池の装着や交換作業を行うことができる。
【０００９】
また、この収容状態において、電池は電極板に設けたバネ状の電極部（第２の電極部）により、排出方向（電池蓋方向）に付勢されている。そして、この状態から電池蓋を開けると、電極板に設けたバネ状の電極部が電池を排出方向に押し出し、容易に電池の抜き取り操作を行うことができる。
したがって、電池を電極軸方向に挿入する小さい挿入口により、電池を収容ボックス部に挿入し、また抜き取るようにした構造であっても、容易に電池の抜き取り操作を行うことできる。また、挿入口及び電池蓋を小さいものとすることができるので、電子機器の美観の向上も容易となる。
【００１０】
以下、本発明による電池収容装置の実施の形態について説明する。
図１は、本発明による電池収容装置としての電池収容部の構成例を示す分解斜視図である。また、図２（Ａ）（Ｂ）は、図１に示す電池収容部に角型２次電池（第１の電池）を収容した状態を示す正断面図及び側断面図である。
また、図３（Ａ）（Ｂ）は、図１に示す電池収容部に単３型電池（第２の電池）を収容した状態を示す正断面図及び側断面図である。さらに、図４（Ａ）（Ｂ）は、図１に示す電池収容部に単３型電池を収容する際の位置決め作用を示す正断面図である。
また、図５は、電池収容部に設けられる電極板を示す平面図である。
【００１１】
図１において、本例の電池収容部は、１本の角型２次電池３０と２本の単３型電池３２とを選択的に収容して用いる構造を有するものである。
角型２次電池３０は、直方体状の電池本体３０Ａの長手方向の一方の端部に一対の電極部（陽極部と陰極部）３０Ｂを有する。そして、本例の電池収容部では、電極部３０Ｂを先頭にして角型２次電池３０を収容ボックス部４０内に挿入して収容するようになっている。
また、単３型電池３２は、円柱体状の電池本体３２Ａの軸方向の一方の端部に陽極部３２Ｂを有するとともに、他方の端部に陰極部３２Ｃを有する。そして、本例の電池収容部では、２本の単３型電池３２のうち、一方の陽極側３２Ｂ側から、他方を陰極部３２Ｃ側から収容ボックス部４０内に挿入して収容するようになっている。
【００１２】
また、本例では、角型２次電池３０は、単３型電池３２の直径より大きい厚みを有するとともに、単３型電池３２の直径の２倍以上の幅を有するものとなっている。また、角型２次電池３０の長さは、単３型電池３２がほぼ等しいものとなっている。
なお、本発明において、上述のような各電池３０、３２の電極部３０Ｂ、３２Ｂ、３２Ｃに沿う方向、すなわち本例では各電池本体３０Ａ、３２Ａの長手方向を電極軸方向というものとする。
【００１３】
また、本例の電池収容部は、電子機器に設けられる収容ボックス部４０を有する。この収容ボックス部４０は、例えば合成樹脂等よりなり、上面と一端部が開放された矩形容器状のボックス本体４０Ａと、この上面を閉蓋するカバー４０Ｂとを有する。
また、収容ボックス部４０の一方の端部は、前記各電池３０、３２を挿入する挿入口４２となっている。
このような収容ボックス部４０は、角型２次電池３０の外周形状に対し、幅方向には、ほぼ対応する幅を有し、厚み方向には、やや大きい厚みをもった内周形状を有する方形筒状に形成されている。
【００１４】
収容ボックス部４０の挿入口４２には、これを閉蓋する電池蓋４４が設けられている。この電池蓋４４は、カバー４０Ｂの端部にヒンジ機構４４Ａを介して設けられ、挿入口４２を開閉するものである。
また、電池蓋４４には、ロック操作片４４Ｂの操作により、挿入口４２を閉蓋した状態で、この閉蓋状態をロックするロック機構（図示せず）が設けられている。
また、ヒンジ機構４４Ａには、ねじりコイルバネ４４Ｃが設けられており、電池蓋４４を開放する方向に付勢している。
【００１５】
また、電池蓋４４の内壁面には、電池蓋４４側に配置される単３型電池３２の陽極部３２Ｂと陰極部３２Ｃとを接続する接続電極部（図示せず）が設けられている。
また、収容ボックス部４０の電池蓋４４と対向する内壁部には、上述のような各電池３０、３２の電極部３０Ｂ、３２Ｂ、３２Ｃに接触するそれぞれ一対の電極部４６Ａ、４６Ｂを設けた端子板（電極板）４６が配置されている。
端子板４６は、例えば合成樹脂等の絶縁材より一体成形によって形成されたものであり、収容ボックス部４０の内壁に接着またはネジ止め等により取付けられている。この端子板４６は、角型２次電池３０用の一対の電極部４６Ａと、単３型電池３２用の一対の電極部４６Ｂと、オプション端子としての電極部４６Ｃとを設けたものである。
【００１６】
角型２次電池３０用の電極部４６Ａは、ロッド状に形成され、図２に示すように、角型２次電池３０の電極部３０Ｂの孔に挿入されるようになっている。
また、単３型電池３２用の電極部４６Ｂは、略Ｕ字状の板バネ状に形成され、図３に示すように、単３型電池３２の各電極部３２Ｂ、３２Ｃに接触するようになっている。
オプション用の電極部４６Ｃは、角型２次電池３０とは異なる舌片状の電極部を有する角型２次電池（図示せず）に対応するものであり、舌片状の電極部を有する角型２次電池が挿着された場合に、舌片状の電極部が挿入されるようになっている。
【００１７】
この場合、角型２次電池３０用の電極部４６Ａは、端子板４６より取り外し可能に設けられており、電極部４６Ａを端子板４６より取り外すことにより、他の角型２次電池に対応できるようになっている。
このように、予め端子板４６にオプション用の電極部４６Ｃを設けておくことで、共通の端子板４６で異なる構造の角型２次電池に対応することが可能である。
なお、オプション用の電極部としては、図示のような電極部４６Ｃに限らず、板バネ状や線バネ状の各種のものを設けることができる。これらは、上述した角型２次電池３０の挿着時には、その電極部３０Ｂに接触することのない状態で配置され、角型２次電池３０と異なる角型２次電池が挿着されたときには、その電極部に接触するように配置する。
【００１８】
また、板バネ状の電極部４６Ｂは、単３型電池３２用の接点としての機能の他に、各電池３０、３２を排出時に押し出すためのバネとして機能する。
すなわち、単３型電池３２の挿着時には、図３（Ｂ）に示すように、板バネ状の電極部４６Ｂが単３型電池３２の電極部３２Ｂ、３２Ｃに圧接して、単３型電池３２を押し出す方向に付勢しており、電池蓋４４を開放することで、単３型電池３２を外方に押し出す。
また、角型２次電池３０の挿着時には、図２（Ｂ）に示すように、板バネ状の電極部４６Ｂが角型２次電池３０の絶縁ケースの端面に圧接して、角型２次電池３０を押し出す方向に付勢しており、電池蓋４４を開放することで、角型２次電池３０を外方に押し出す。なお、舌片状の電極部を有する角型２次電池についても同様である。
したがって、このような板バネ状の電極部４６Ｂの作用により、各電池３０、３２を容易に取り出すことができる。
【００１９】
また、収容ボックス部４０を構成するボックス本体４０Ａの上面側の両側縁部には、各電池３０、３２の挿入方向と直交する方向に２本の支持軸（支持機構の枢軸）５０、５２が架設されており、これら支持軸５０、５２には、仕切り板（仕切り部材）５４、５６が支持されている。
支持軸５０、５２は、収容ボックス部４０を長手方向にほぼ３等分する位置に配置され、その両端部がボックス本体４０Ａの内壁部に固定されている。また、各仕切り板５４、５６は、各支持軸５０、５２に回転可能に支持されている。
【００２０】
また、ボックス本体４０Ａの内壁部には、各支持軸５０、５２の一方の端部に近接する位置に、それぞれストッパ６０、６２が設けれており、それぞれ仕切り板５４、５６の回転位置を規制するようになっている。なお、詳しくは、各仕切り板５４、５６に設けた係合片５４Ａ、５６Ａがストッパ６０、６２に係合することにより、各仕切り板５４、５６の回転位置が各電池３０、３２の挿入方向と略直交する平面上で止まるようになっている。
したがって、各仕切り板５４、５６は、各支持軸５０、５２を中心に回転し、カバー４０Ｂの内壁面にほぼ当接する位置（折り畳み位置）からボックス本体４０Ａ側にほぼ垂直に垂れ下がってストッパ６０、６２に当接する位置（直立位置）まで、約９０°の範囲で変位することができる。
【００２１】
そして、支持軸５０、５２には、各仕切り板５４、５６を直立位置側に回転付勢するねじりコイルバネ６４、６６が設けられている。すなわち、各ねじりコイルバネ６４、６６は、コイル部に支持軸５０、５２を通された状態で挿着され、一方の端部が仕切り板５４、５６の係合片５４Ａ、５６Ａに係止され、他方の端部がカバー４０Ｂの内壁面に係止されている。そして、仕切り板５４、５６にねじり力を付与し、各仕切り板５４、５６をストッパ６０、６２に当接する方向に付勢している。
【００２２】
また、以上のように支持された仕切り板５４、５６は、２つの単３型電池３２の外周形状に対応する２つの円弧部５４Ｂ、５４Ｃ、５６Ｂ、５６Ｃを有するものである。
すなわち、仕切り板５４、５６は、各電池３０、３２の挿入方向と略直交する平面上で、カバー４０Ｂの内壁面（第１の内壁面）と、この内壁面に臨む２本の単３型電池３２の外周面との間に形成される間隙部にほぼ対応する形状を有している。
【００２３】
また、仕切り板５４、５６の各円弧部５４Ｂ、５４Ｃ、５６Ｂ、５６Ｃの間には、２つの単３型電池３２を互いに離間して配置するためのセパレータ部５４Ｄ、５６Ｄが設けられている。このセパレータ部５４Ｄ、５６Ｄによって、２つの単３型電池３２が互いに離間して配置されるため、両者の接触がなくなり、液漏れやショートを防止できる。
【００２４】
また、ボックス本体４０Ａのカバー４０Ｂと反対側の内壁面には、各電池３０、３２の挿入をガイドする突起部６８が設けられている。なお、角型２次電池３０には、突起部６８が係合する溝部３０Ｃが形成されている。
また、ボックス本体４０Ａには、通電ライン等を形成するフレキシブル基板７０が設けられ、ボックス本体４０Ａとカバー４０Ｂの間隙部より収容ボックス部４０の外部に導かれ、電子機器の本体装置側に接続されるようになっている。
また、以上のような構成の電池収容部は、例えばカバー４０Ｂに設けたネジ孔７２を介して、止めネジ７４により電子機器の本体装置に固定されるようになっている。
【００２５】
次に、以上のような構成の電池収容部における電池３０、３２の挿入時の作用について説明する。
まず、角型２次電池３０を収容ボックス部４０に挿入すると、仕切り板５４、５６は、角型２次電池３０の先端部に押され、ねじりコイルバネ６４、６６の力に抗して支持軸５０、５２を中心に回転し、図２に示すように、カバー４０Ｂの内壁面に沿って折り畳んだ状態となる。
これにより、角型２次電池３０全体が収容ボックス部４０に収容でき、また、角型２次電池３０の電極部３０Ｂが収容ボックス部４０内の電極部４６Ａに接触する。この状態で、収容ボックス部４０を電池蓋４４で閉蓋し、角型２次電池３０を収容ボックス部４０内部に位置決め保持できる。
【００２６】
また、角型２次電池３０を収容ボックス部４０より抜き取る場合には、電池蓋４４を開放することにより、容易に抜き取ることができる。この際、板バネ状に形成した電極部４６Ｂのバネ力が角型２次電池３０を押し出す方向に作用し、また、折り畳まれた仕切り板５４、５６が付勢部材の力によって復帰することにより、角型２次電池３０を押し出す方向に作用し、スムーズに抜き取ることができる。
【００２７】
また、単３型電池３２を収容ボックス部４０に挿入すると、仕切り板５４、５６が単３型電池３２の外周形状に対応する形状を有するため、単３型電池３２は仕切り板５４、５６を避ける状態で収容ボックス部４０で挿入される。
なお、図４（Ａ）に示すように、単３型電池３２の挿入方向がずれた状態で挿入操作された場合、最初はセパレータ部５４Ｄ、５６Ｄが押されて仕切り板５４、５６が倒れた状態となるが、単３型電池３２が突起部６８に接触することにより、その挿入方向が修正されるとともに、ねじりコイルバネ６４、６６の力によって仕切り板５４、５６が直立する方向に回転変位し、円弧部５４Ａ、５４Ｂ、５６Ａ、５６Ｂによって単３型電池３２の位置が修正され、図４（Ｂ）に示すように、単３型電池３２が適正な位置に配置される。
【００２８】
これにより、単３型電池３２の電極部３２Ｂ、３２Ｃが収容ボックス部４０内の電極部４６Ｂに適正に接触できる。また、この状態で、仕切り板５４、５６が完全に直立した状態となり、単３型電池３２を収容ボックス部４０内でガタ付きなく位置決め保持できる。そして、収容ボックス部４０を電池蓋４４で閉蓋し、単３型電池３２を収容ボックス部４０内部に位置決め保持できる。
【００２９】
また、単３型電池３２を収容ボックス部４０より抜き取る場合には、電池蓋４４を開放することにより、容易に抜き取ることができる。この際、板バネ状に形成した電極部４６Ｂのバネ力が単３型電池３２を押し出す方向に作用し、スムーズに抜き取ることができる。
以上のようにして、共通の電池収容部に角型２次電池３０と単３型電池３２を容易に挿着でき、容易に交換することができる。
【００３０】
図６は、上述した電池収容装置を適用した電子機器の一例としての携帯型ビデオカメラ装置の構成例を示す斜視図である。
本例のビデオカメラ装置は、カートリッジ１００をカメラ本体２００の本体ケース２００Ａに設けた収容部２１０に挿着して、カメラ本体２００で撮影したビデオ信号をカートリッジ１００内のビデオテープに記録するようにしたものである。
カートリッジ１００は、矩形筐状に形成されており、収容部２１０は、カートリッジ１００の外周形状に対応する形状に形成されている。また、収容部２１０は、本体ケース２００Ａの一側部に開口しており、この開口部２１０Ａよりカートリッジ１００を挿入するようになっている。
【００３１】
また、開口部２１０Ａの後面側の縁部には、ヒンジ機構３００が設けられており、このヒンジ機構３００を介して開口部２１０Ａを開閉する開閉蓋３１０が設けられている。
なお、開閉蓋３１０の内側には、開口部２１０Ａの一部と係合ロックされるロック部３１０Ａが設けられており、閉蓋した開閉蓋３１０が不用意に開かないようになっている。
【００３２】
カートリッジ１００には、ビデオテープを巻回した供給側と巻取り側の各リールと、ビデオテープへの記録、再生を行う磁気ヘッドを搭載した回転ヘッドドラム機構と、ビデオテープを回転ヘッドドラムに斜めに巻回するローディング機構とを内蔵（ともに図示せず）したものである。
すなわち、本例のビデオカメラ装置では、各テープリール、回転ヘッドドラム機構、ローディング機構より構成される記録再生機構が、カートリッジ１００内に設けられており、ビデオテープへの情報の記録動作及び再生動作は、全てカートリッジ１００の内部で行われるようになっている。
【００３３】
一方、カメラ本体２００には、ビデオ撮影用の光学系やＣＣＤ等の撮像素子、さらにはカラーフィルタ等を含む撮像装置が設けられており、本体ケース２００Ａの前面部には対物レンズ２２０が配置されている。
また、本体ケース２００Ａの内部には、撮像装置による撮像信号を記録用のビデオ信号に変換するための各種処理回路等を搭載した配線基板２３０が配置されている。
【００３４】
また、カートリッジ１００の端部と本体ケース２００Ａの内部には、互いに接合されるコネクタ（図示せず）が設けられている。そして、カートリッジ１００を収容部２１０に挿着することにより、カートリッジ１００側のコネクタと本体ケース２００Ａ側のコネクタとが機械的に接続され、カートリッジ１００側の回路とカメラ本体２００側の回路とが接続される。
なお、収容部２１０には、カートリッジ１００の挿入をガイドするガイドレール（図示せず）が設けられており、このガイドレールに沿ってカートリッジ１００を挿入することにより、各コネクタ同士が接合されるようになっている。
【００３５】
そして、このようなビデオカメラ装置では、開閉蓋３１０が厚肉の板状に形成され、その内部に上述した電池収容部が設けられている。そして、開閉蓋３１０を閉じた状態で、開閉蓋３１０とビデオカメラ本体２００とに設けた接点４２０、４３０が接触し、電源部からビデオカメラ本体２００への給電ラインが接続されるようになっている。
また、ビデオカメラ本体２００側には２次電源回路を設けて、開閉蓋３１０を開いた状態でも、一定時間の電源供給を継続できるようにしている。
【００３６】
なお、本発明の電池収容装置は、上述のようなビデオカメラ装置に限らず、ヘッドホンステレオやＣＤプレーヤ等のように、他の各種携帯型電子機器の電池収容部として広く適用し得るものである。また、以上の例では、長さの等しい電池３０、３２を収容する例について説明したが、長さの異なる電池を収容する場合には、電池ボックス部側の電極部を電池の長さ方向に変位可能に配置した電極板（端子板４６）上に設け、この電極板を圧縮コイルスプリング等の伸縮バネ部材によって付勢することにより、電池ボックス部に収容された電池の長さに応じて電極部が変位できるようにし、電池の長さに対応させるようにしてもよい。
【００３７】
また、以上の例は、電極部の形状が異なる角型２次電池３０と単３型電池３２とを併用する構造であるため、それぞれの電池３０、３２に対して異なる電極部４６Ａ、４６Ｂを設けたが、形状が共通する電極部を有する電池を併用する場合には、収容部側の電極部を共用する構造とすることも可能である。
また、以上の例は、角型２次電池３０と単３型電池３２とを併用する場合を説明したが、本発明はこれに限らず、形状の異なる各種の電池の組み合わせに対応することができ、角型２次電池以外の直方体状の電池と、単３型電池以外の円柱体状の電池とを併用する電池収容部に広く適用することができるものである。
【００３８】
また、以上の例は、各電池３０、３２を押し出すためのバネ状の電極部４６Ｂを、略Ｕ字状の板バネとしたが、他の形状の板バネであってもよいし、あるいは円錐形の圧縮コイルバネ状に形成してもよい。
【００３９】
【発明の効果】
以上説明したように本発明の電池収容装置及び電子機器では、収容ボックス部に収容される角型２次電池と２つの円柱型電池の外周形状の差を補間するための仕切り部材を設け、角型２次電池を収容する場合と、２つの円柱型電池を収容する場合とで、仕切り部材が回転して変位することにより、角型２次電池と２つの円柱型電池のいずれに対しても位置決め保持できるようにし、さらに、共通の電極板に第１の電極部と第２の電極部を設け、収容ボックス部に角型２次電池が挿入された場合に、角型２次電池に電極部に第１の電極部が接触するとともに、第２の電極部は接触せず、２つの円柱型電池が挿入された場合に、２つの円柱型電池の電極部に第２の電極部が接触するとともに、第１の電極部は接触しないように配置した。
このため、外周形状の異なる複数種類の電池に対して共通の構造で対応でき、かつ、特別な操作を行うことなく複数種類の電池交換を容易に行うことができる電池収容装置を提供することができる効果がある。
【００４０】
また本発明では、第２の電極部は、収容ボックス部内に収容された各電池を排出方向に付勢するバネ状に形成され、２つの円柱型電池が挿入された場合には、それら２つの円柱型電池の電極部及び排出用のバネとして機能するとともに、角型２次電池が挿入された場合には、その角型２次電池の排出用のバネとして機能するようにした。
このため、１種類の電極部によって複数種類の電池に対する排出用バネを実現できるので、各電池毎に個別に排出用バネを設ける場合に比し、構造の簡素化と部品点数の削減を達成でき、コストダウンを図ることができる効果がある。
また本発明では、収容ボックス部が電池を電極軸方向に挿入する構造であるため、挿入口及び電池蓋を小さいものとすることができ、電子機器の美観の向上も容易となり、電子機器の設計状の自由度を向上できる効果がある。
