【０００１】
【産業上の利用分野】
本発明は、充電可能な二次電池や乾電池等の一次電池を収納体に収納したバッテリ装置及びこのバッテリ装置を電源に用いるビデオカメラやビデオテープレコーダ等の電子機器に関する。
【０００２】
【従来の技術】
携帯型のビデオカメラ、ビデオテープレコーダ、テーププレーヤあるいはディスクプレーヤ等の電子機器においては、駆動電源として直流変換アダプタを介して供給される商用電源のほかに、充電型の電池や乾電池等の直流電源が使用可能に構成されている。
【０００３】
従って、この種の電子機器においては、機器本体の一部にバッテリ装着部が設けられ、このバッテリ装着部に充電型の電池や乾電池等の電池を収納したバッテリ装置が装着される。また、充電型の電池を内蔵したバッテリ装置は、充電容量が消耗した場合には、直流変換アダプタを備える充電器に装着されて充電が行われる。
【０００４】
ところで、ビデオカメラやビデオテープレコーダ等の電子機器に用いられるバッテリ装置は、装着される電子機器を駆動させるに足る電圧を確保し、あるいは電子機器を一定時間以上駆動させるに足る容量を確保するため、複数本のバッテリを収納体に収納させて構成されている。この種のバッテリ装置として、２本の円筒状をなす充電型の電池を収納体内に並列配置して構成したものが用いられている。
【０００５】
この円筒状に形成された２本の充電型の電池１，１を収納したバッテリ装置２は、図２６に示すように、内部に２本の充電型の電池１，１を並列して収納するに足る電池収納部３を形成した収納体４を備えている。この収納体４は、図２７に示すように、合成樹脂をモールド成形して形成され、電池収納部３に並列配置された電池１，１を密封して収納するように構成されている。収納体４に収納された２本の電池１，１は、電池収納部３内に配設された図示しない電極板を介して直列接続されている。
【０００６】
また、電池収納部３に２本の電池１，１を並列配置して収納した収納体４の底面側には、このバッテリ装置２が装着される電子機器側の接続端子と電気的に接続される正極端子５及び負極端子６が埋設されとともに、これら正極端子５及び負極端子６と電極板間を電気的に接続する図示しない接続線が設けられた端子取付け板７が一体に形成されている。この端子取付け板７に設けられた正極端子５及び負極端子６は、図２８に示すように、このバッテリ装置２が装着される電子機器側に設けられたピン状の接続端子が挿入嵌合して電気的に接続されるように筒状に形成されている。これら筒状に形成された正極端子５及び負極端子６は、開口端５ａ，６ａを、バッテリ装置２の電子機器に対する装着方向側となる端面８に臨まされて端子取付け板７の両側に位置して取付けられている。
【０００７】
なお、バッテリ装置２の底面側には、このバッテリ装置２を電子機器に装着したとき、電子機器側に設けられた移動操作部材によって移動操作され、一旦電子機器に装着され使用状態に置かれたことを表示する使用状態表示部材２９が設けられている。
【０００８】
上述のように形成されたバッテリ装置２は、並列配置した２本の電池１，１の外形に対応するように略直方体形状をなすように形成されている。なお、収納体４の端子取付け板７が一体に形成された底面側と対向する上面９側の両側は、電池収納部３に収納された電池１，１の外周形状に倣った円弧部１０，１０となされている。このように上面９側の両側に円弧部１０，１０が形成されることにより、このバッテリ装置２は、上下が非対象の形状となされ上下方向を容易に判別することが可能となる。
【０００９】
上述したバッテリ装置２は、図２９に示すように、ビデオカメラ１２の外筺１３の一部に構成されたバッテリ装着部１４に収納するようにして装着が可能となる。すなわち、バッテリ装置２の全体を収納するに足る大きさのバッテリ装着部１４を外筺１３の一部に形成する。このバッテリ装着部１４は、外筺１３の一部を区画して形成されてなるものであって、バッテリ装置２が挿脱される挿脱口１５と対向する内方側に壁面にバッテリ装置２に設けた正極端子５及び負極端子６が嵌合する一対の接続ピン１７，１８が設けられている。
【００１０】
そして、バッテリ装置２は、正極端子５及び負極端子６の開口端５ａ，６ａが臨まされた端面８側を挿入端として、挿脱口１５を介して図２９中矢印Ａ方向に挿入していくことによりバッテリ装着部１４に装着される。このとき、正極端子５及び負極端子６がそれぞれ接続ピン１７，１８に嵌合し、バッテリ装置２がビデオカメラ１２に電気的に接続され、電池１，１の電源がビデオカメラ１２に供給可能な状態となされる。
【００１１】
ところで、バッテリ装置２の収納体４の上面９には、図２６及び図２７に示すように、バッテリ装着部１４に対する誤挿入を防止するための誤挿入防止溝１１が設けられている。この誤挿入防止溝１１は、バッテリ装着部１４に対する挿入側の端面８に開口端１１ａを有し、収納体４の中途部に亘ってバッテリ装着部１４に対する装着方向と平行に形成されている。そして、バッテリ装着部１４の内側面に、挿脱口１５から中途部に亘って誤挿入防止溝１１が係合する突条部１９が突設されている。このように、バッテリ装置２側に誤挿入防止溝１１を設け、バッテリ装着部１４側に誤挿入防止溝１１が係合する突条部１９を設けることにより、バッテリ装置２は、正しく挿入側の端面８を挿入端とし、さらに誤挿入防止溝１１を突条部１９に対応させて挿入されたときのみバッテリ装着部１４への装着が可能となり、バッテリ装着部１４への誤挿入が禁止される。
【００１２】
また、電源の容量を増大させるため、図３０に示すように、収納体４内にさらに直列接続された２本の電池１を収納し、合計４本の電池１を収納した第２のバッテリ装置２２が提案されている。この第２のバッテリ装置２２は、図３１に示すように、並列配置した２本の電池１，１の上にさらに並列配置した２本の電池１，１を積み重ねるように収納体２４に収納したものである。このように並列配置された２本ずつの電池１を積み重ねるように収納体２４内に収納した第２のバッテリ装置は、ビデオカメラ１２側に設けられた接続ピン１７，１８に嵌合する正極端子５及び負極端子６が埋設された端子取付け板７の構成を、２本の電池１，１を収納した第１のバッテリ装置２と共通にすることができる。さらに、図３０及び図３１に示す第２のバッテリ装置２２は、並列配置した２本の電池１，１の上にさらに並列配置した２本の電池１，１を積み重ねるように収納してなることから、第１のバッテリ装置２と高さＨ₁ のみを異にし、幅Ｗ₁ を共通にして外観の形態を略共通にするすることができる。そして、外観の形態が略共通に構成されてなるので、バッテリ装着部に対する誤挿入を防止する誤挿入防止溝１１も、第１及び第２のバッテリ装置２及び２２で一致した構成とすることができる。
【００１３】
さらにまた、第２のバッテリ装置２２は、２本ずつの電池１を積み重ねるように収納体２４内に収納してなるので、電池１の収納効率を高めることができ、装置自体の小型化を図ることができ、このバッテリ装置２２が装着される電気機器側のバッテリ装着部も小型化するができる。
【００１４】
【発明が解決しようとする課題】
ところで、２本の電池１を収納した第１のバッテリ装置２と４本の電池を収納した第２のバッテリ装置２２とは、共通の電子機器に選択的に装着可能となすことが望ましい。例えば、ビデオカメラ１２を長時間に亘って使用する場合には、４本の電池を収納した第２のバッテリ装置２２を装着し、短時間の使用を目的とするときには、ビデオカメラ１２の操作性を考慮して軽量な２本の電池を収納した第１のバッテリ装置２を装着することが望ましい。
【００１５】
そこで、２本の電池１を収納した第１のバッテリ装置２と４本の電池１を収納した第２のバッテリ装置２２を選択的に装着可能となすためには、ビデオカメラ１２側に設けられるバッテリ装着部２５を、図３２に示すように、大型の第２のバッテリ装置２２の全体を収納するに足る大きさに形成する必要がある。
【００１６】
ところで、第２のバッテリ装置２２は、図３１に示すように、円筒状の大きさを共通にする並列配置した２本の電池１，１の上にさらに大きさを共通にする２本の電池１，１を積み重ねるように並列配置して収納してなるので、端面２８の形状が略正方形となされて、この端面２８の対角線方向に長さＳ₁ が第１のバッテリ装置２の幅Ｗ₁ と略一致する。従って、大型の第２のバッテリ装置２２を装着可能となすバッテリ装着部２５に小型の第１のバッテリ装置２に装着しようとすると、第１のバッテリ装置２は、バッテリ装着部２５の底面２５ａに端子取付け板７を沿わせて挿入されて、正極端子５及び負極端子６がバッテリ装着部２５内の接続ピン１７，１８に嵌合する正規の装着状態のみならず、図３３中一点鎖線及び二点鎖線で示すように、バッテリ装着部２５の対角線方向に傾斜して挿入して装着することも可能となってしまう。さらに、第１のバッテリ装置２は、図３３中破線で示すように、バッテリ装着部２５に上面２５ｂ側に上面９を沿わせて装着することも可能である。このように、第１のバッテリ装置２が、バッテリ装着部２５に対し傾斜し、あるいは上面２５ｂ側に偏倚して装着されると、正極端子５及び負極端子６とバッテリ装着部２５側の接続ピン１７，１８との相対嵌合が実現されなくなる。その結果、第１のバッテリ装置２は、ビデオカメラへの電気的な接続が図れない誤装着状態となされてしまう。
【００１７】
また、電池は、電気機器を構成するための部品に比し重いものであるので、この電池を収納したバッテリ装置も重量のあるものとなってしまう。特に、複数の電池を収納体に収納して構成したバッテリ装置は、収納する電池の数に応じて重量が大きくなってしまう。このように複数の電池を収納し、大きな重量を有するバッテリ装置を、装着姿勢を正しく正確に位置決めを図ってバッテリ装着部に装着させることが困難となる。そして、重量の大きなバッテリ装置が、正確に位置決めされることなくバッテリ装着部に装着され、装着された電子機器内で振動すると、この電子機器に大きな衝撃を与え、このバッテリ装置が装着される電子機器を損傷させる危険もある。特に、バッテリ装置と電子機器間を電気的に接続する接続端子は、衝撃により容易に損傷してしまう。
【００１８】
そこで、本発明の目的は、電子機器に対し正確に位置決めを図って装着し、装着される電子機器の保護を十分に図ることを可能となすバッテリ装置を提供することにある。
【００１９】
また、本発明の目的は、収納する電池の本数を異にし、大きさを異にするバッテリ装置を選択的に装着可能となす電子機器側のバッテリ装着部に対し、誤挿入を防止し、確実に装着することを可能となすバッテリ装置を提供することにある。
【００２０】
さらに、本発明の目的は、大きさを異にするバッテリ装置を選択的に装着可能となすバッテリ装着部に対し、正確に位置決めされて装着できるバッテリ装置を提供することにある。
【００２１】
さらにまた、本発明の目的は、相対嵌合される接続端子の保護を図り、安全且つ確実に接続端子の接続を可能となすバッテリ装置を提供することにある。
【００２２】
さらにまた、本発明の目的は、大きさを異にするバッテリ装置を選択的に正確に装着可能となすバッテリ装着部を備えた電子機器を提供することにある。
【００２３】
さらにまた、本発明の目的は、バッテリ装置及びバッテリ装着部に設けられる相対嵌合する接続端子の保護を図り、安全且つ確実にバッテリ装置の装脱を可能となす電子機器を提供することにある。
【００２４】
【課題を達成するための手段】
本発明に係るバッテリ装置は、第１の接続端子と第１及び第２の突条部と嵌合突部とが形成されてなるバッテリ装着部が設けられた筺体を備えた電子機器に装着可能に構成されたバッテリ装置であって、上記バッテリ装置は、収納体の上記電子機器への挿入方向と平行な相対向する両側面に、上記挿入方向と直交する高さ方向の略中間に位置して、上記挿入方向側の端面に開口端を有する上記挿入方向と平行に形成された第１及び第２の溝部と、上記収納体の上記電子機器への挿入方向側の端面に、上記電子機器側に設けられる第１の接続端子に電気的に接続される第２の接続端子と、上記収納体の電子機器への挿入方向側の端面であって、上記電池収納部に収納された電池の端面に対向しない位置に、上記挿入方向と平行に穴部とを備え、上記穴部は上記嵌合突部と相対嵌合可能に構成されると共に、上記穴部の挿入方向の長さは上記第２の接続端子のその長さより大きくされて形成されている。
【００２５】
このバッテリ装置は、さらに加え上記収納体の挿入方向側の端面及び相対向する両側面に直交する面に、上記収納体の幅方向の略中間に位置して、上記挿入方向側の端面に開口し、上記挿入方向側の端面から上記収納体の中途部に亘って上記挿入方向と平行に形成された第３の溝部が設けられる。
【００２６】
また、本発明に係るバッテリ装置は、上記挿入方向側の端面から上記収納体の中途部に亘って上記挿入方向と平行に形成された上記第３の溝部の挿入方向の長さは上記穴部のその長さより大きく形成されている。
【００２７】
そして、本発明に係るバッテリ装置は、上記第１、第２及び第３の溝部は、上記電池収納部に互いに平行に隣接収納された電池間に形成される空間に、上記収納体の一部を内方に膨出させて形成されてなる。
【００２８】
また、本発明に係るバッテリ装置は、上記挿入方向と平行に形成された上記穴部は、断面略三角形状に形成されている。
【００２９】
そして、上記バッテリ装置に設けられた上記穴部は、断面方向の最大長さがその深さより小さく形成されている。
【００３０】
上述の本発明に係る電子機器は、４本の筒状の電池が上下及び左右に互いに平行に隣接して収納されるバッテリ収納部が設けられた収納体の電子機器への挿入方向と平行な相対向する両側面に、上記挿入方向と直交する高さ方向の略中間に位置して、上記挿入方向側の端面に開口し、上記挿入方向側の端面から上記収納体の中途部に亘って上記挿入方向と平行に形成された第１及び第２の溝部が設けられたバッテリ装置が挿入装着されるに足る大きさのバッテリ装着部が設けられた筺体を備えた電子機器本体を備え、上記バッテリ装着部の相対向する内側面に上記バッテリ装置の第１及び第２の溝部が相対係合する第１及び第２の突条部が形成され、上記バッテリ装着部の上記バッテリ装置の挿入方向と対向する端面に、上記バッテリ装置の挿入方向側の端面に設けた第２の接続端子が電気的に接続される第１の接続端子が設けられ、上記バッテリ装着部の上記バッテリ装置の挿入方向と対向する端面に、上記バッテリ装置の上記収納体の挿入方向側の端面に設けられた穴部が相対嵌合する嵌合突部を設けられ、上記嵌合突部の長さは上記第１の接続端子又は上記第２の接続端子の長さより大きくされて形成されている。
【００３１】
上記電子機器は、さらに、上記バッテリ装着部の相対向する内側面に直交し、上記バッテリ装置の挿入方向と平行な面に、上記バッテリ装置の収納体の相対向する両側面に直交し上記バッテリ装着部への挿入方向と平行な面に形成された第３の溝部が相対係合する第３の突条部が形成されている。
【００３２】
上記バッテリ装置及びバッテリ装着部に設けられる各接続端子は、一方が接続ピンであり、他方が上記接続ピンが嵌合する筒状の接続端子となされている。
【００３３】
【作用】
本発明に係るバッテリ装置は、収納体に設けた第１及び第２の溝部をこのバッテリ装置が装着されるバッテリ装着部側に設けた突条部に相対係合させて装着することにより、バッテリ装着部に対する装着位置の位置決めが図られて装着される。
【００３４】
そして、収納体の電子機器への挿入方向側端面と対向する他方の端面側が閉塞された第１及び第２の溝部が設けられたバッテリ装置は、挿入方向側の端面を挿入端としたときにのみバッテリ装着部への装着が可能となり、逆向きで挿入された場合には、他方の端面の一部がバッテリ装置側に設けた突条部に当接して挿入が禁止される。また、収納体に設けた第３の溝が相対係合する突条部をバッテリ装着部側に形成しておくことにより、上下を逆向きにした挿入が禁止される。
【００３５】
電池収納部が設けられた収納体の電子機器への挿入方向側の端面であって、上記電池収納部に収納された電池の端面に対向しない位置に、上記挿入方向と平行に穴部を形成したバッテリ装置にあっては、このバッテリ装置が装着されるバッテリ装着部側に上記穴部が嵌合する嵌合突部を設けておくことにより、上記穴部と上記嵌合突部とが相対嵌合することにより、バッテリ装置は、バッテリ装着部に対する正確な位置決めが図られて装着される。また、バッテリ装置のバッテリ装着部への装着操作時に、嵌合突部に嵌合する穴部が挿入ガイド部として機能するので、収納体の外周面を挿入ガイド面とする必要がなくなるので、収納体の外面に擦過傷が発生することを防止できる。
【００３６】
本発明に係る電子機器は、４本の筒状をなす電池が上下及び左右に互いに平行に隣接して電池収納部に収納したバッテリ装置が装着されるとき、このバッテリ装置に設けた第１及び第２の溝部が、バッテリ装着部の相対向する内側面に形成された第１及び第２の突条部に相対係合する。この電子機器は、バッテリ装置を各突条部により挿入方向をガイドして挿入させ、これら突条部に第１及び第２の溝部を相対係合させることにより、バッテリ装置を正確に位置決めして装着させる。
【００３７】
また、電子機器は、４本の電池を収納したバッテリ装置が装着されるとき、このバッテリ装置に設けた第３の溝部に第３の突条部を係合させる。そして、４本の電池を収納したバッテリ装置が上下を逆にしてバッテリ装着部に挿入されるときには、収納体の挿入側端面の一部に第３の突条部を当接させて誤挿入を防止する。
【００３８】
さらに、本発明に係る電子機器は、４本の電池を収納したバッテリ装置が穴部を設け挿入側の端面からバッテリ装着部に挿入されると、上記穴部に嵌合突部を嵌合させる。バッテリ装置は、穴部に嵌合突部を嵌合させてバッテリ装着部に装着されることにより、バッテリ装置側の接続端子（第２の接続端子）と電子機器側の接続端子（第１の接続端子）との相対嵌合が図られて電気的な接続が行われる。この電子機器は、バッテリ装置に設けられた穴部に相対嵌合する嵌合突部を、バッテリ装置及びバッテリ装着部に設けられた接続端子となる接続ピン及び筒状の接続端子より長尺に形成してなるので、穴部に嵌合突部が嵌合し、バッテリ装置のバッテリ装着部に対する装着位置が位置決めされた後、接続ピンと筒状の接続端子との接続が行われる。
【００３９】
さらにまた、この電子機器は、バッテリ装置が穴部を設けた挿入側の端面とは逆の平坦な端面側からバッテリ装着部に挿入されると、この平坦な端面をバッテリ装着部内に設けた嵌合突部に当接させ、バッテリ装置のさらなる挿入を不可能とすることによって誤挿入を防止する。
【００４０】
【実施例】
以下、本発明に係るバッテリ装置及びこのバッテリ装置が装着される電気機器の具体的な実施例を図面を参照して説明する。
【００４１】
本実施例のバッテリ装置３１は、円筒状に形成された４本の充電型の電池１を収納したものである。このバッテリ装置３１は、図１、図２及び図３に示すように、内部に４本の電池１を上下及び左右に互いに平行に隣接して収納するに足る大きさの電池収納部３２を形成した収納体３３を備えている。この収納体３３は、合成樹脂をモールド成形して形成された互いに突き合わせ結合される上ケース半体３４と、中ケース半体３５と、収納体３３の底板を構成するとともにこのバッテリ装置２が装着される電子機器側の接続端子と電気的に接続される正極端子３７及び負極端子３８が埋設される端子取付け板３６とから構成されている。これら上ケース半体３４、中ケース半体３５及び端子取付け板３６は、絶縁材料である合成樹脂をモールド成形して形成されている。そして、収納体３３は、上ケース半体３４、中ケース半体３５及び端子取付け板３６が互いに突き合わせ結合することによって、内部に４本の電池１を収納するに足る空間である電池収納部３２が構成される。
【００４２】
そして、４本の電池１は、図２及び図３に示すように、上下及び左右に互いに平行に隣接して配置されて電池収納部３２内に収納される。そして、収納体３３を構成する上ケース半体３４、中ケース半体３５及び端子取付け板３６は、４本の電池１を収納した状態で互いの突き合わせ面が接着あるいは溶着によって接合されることによって、これら４本の電池１を電池収納部３２に密封した状態で収納した収納体３３を構成する。
【００４３】
ところで、収納体３３に収納された４本の電池１は、２本ずつ直列接続され、さらに収納体３３内に配設した図示しない電極板を介して直列接続された２本ずつの電池１，１が並列に接続されている。
【００４４】
そして、収納体３３の底板を構成する端子取付け板３６には、本実施例のバッテリ装置３１が装着される電子機器側の接続端子と電気的に接続される正極端子３７及び負極端子３８が埋設されとともに、これら正極端子３７及び負極端子３８と電極板間を電気的に接続する図示しない接続線が配設されている。この端子取付け板３６に設けられた正極端子３７及び負極端子３８は、図１及び図２に示すように、本実施例のバッテリ装置３１が装着される電子機器側に設けられたピン状の接続端子が挿入嵌合して電気的に接続されるように筒状に形成されている。また、筒状に形成された正極端子３７及び負極端子３８は、開口端３７ａ，３８ａを、バッテリ装置３１の電子機器に対する装着方向側となる端面３９に臨まされて端子取付け板３６の一端面側の両側に位置して取付けられている。
【００４５】
上述のように構成されたバッテリ装置３１は、上下及び左右に互いに平行に隣接して配置した４本の電池１の外形に対応するように略直方体形状をなすように形成されている。なお、端子取付け板３６が一体に設けられた底面側と対向する収納体３３の上面３９側を構成する上ケース半体３４の両側は、電池収納部３２に収納された電池１の外周形状に倣った円弧部４０，４０となされている。このように上面３９側の両側に円弧部４０，４０が形成されることにより、このバッテリ装置３１は、上下が非対象の形状となされ上下方向を容易に判別することが可能となる。
【００４６】
本実施例のバッテリ装置３１には、図１及び図２に示すように、正極端子３７及び負極端子３８の各開口端３７ａ，３８ａが臨む電子機器への挿入側の端面４１と直交する両側面４２，４３に、このバッテリ装置３１が装着される後述する電子機器のバッテリ装着部に設けられた第１及び第２の突条部が相対係合する第１及び第２の溝部４４，４５が設けられている。これら第１及び第２の溝部４４，４５は、バッテリ装置３１の電子機器への挿入方向と平行に、収納体３３の電子機器に対する挿入方向と直交する高さ方向の略中間に位置し、挿入方向側の端面４１に開口端４４ａ，４５ａを臨ませ、挿入方向側の端面４１から収納体３３の中途部に亘って形成されている。すなわち、第１及び第２の溝部４４，４５は、挿入方向側の端面４１と対向する他方の端面４６側を閉塞させて、バッテリ装置３１の電子機器への挿入方向と平行に形成されている。
【００４７】
さらに具体的には、第１及び第２の溝部４４，４５は、図３に示すように、電池収納部３２に上下に互いに平行に隣接配置された電池１₁ ，１₃ 及び電池１₂，１₄ との間に形成される空間に収納体３３を構成する中ケース３５の一部を内方に膨出させるようにして形成されてなる。このように、第１及び第２の溝部４４，４５は、上下に互いに平行に隣接配置された電池１₁ ，１₃ 及び電池１₂ ，１₄ との間に形成されてなるので、上下及び左右に互いに平行に隣接して配置した４本の電池１を収納した収納体３３の高さ方向の略中間に位置して設けられるようになる。
【００４８】
また、収納体３３の挿入方向側の端面４１及び相対向する両側面４２，４３に直交する面である収納体３３の上面３９を構成する上ケース半体３４の上面壁には、図１に示すように、このバッテリ装置３１が装着される電子機器のバッテリ装着部に設けられる第３の突条部が相対係合する第３の溝部５１が設けられている。この第３の溝部５１は、収納体３３の幅方向の略中間に位置して、挿入方向側の端面４１に開口端５１ａを臨ませ、挿入方向側の端面４１から収納体３３の中途部に亘って挿入方向と平行に形成されている。すなわち、第３の溝部５１は、他方の端面４６側を閉塞させて、バッテリ装置３１の電子機器への挿入方向と平行に形成されている。この第３の溝部５１は、バッテリ装置３１のバッテリ装着部に対する上下方向の誤挿入を規制するものである。
【００４９】
さらに、収納体３３の挿入方向側の端面４１には、図１に示すように、このバッテリ装置３１が装着される電子機器のバッテリ装着部側に設けられる嵌合突部が相対嵌合する穴部５２が設けられている。この穴部５２は、電池収納部３２に収納された４本の電池１₁ 〜１₄ のいずれの端面にも対向しない各電池１₁ 〜１₄ 間に構成される空間に位置して形成されてなるものであって、図３に示すように、電池収納部３２に上下及び左右に互いに平行に隣接して配置された４本の電池１₁ 〜１₄ によって囲まされた空間内に位置するようにして、バッテリ装置３１のバッテリ装着部への装着方向と平行に設けられている。穴部５２は、収納体３３の挿入方向側の端面４１の一部をバッテリ装着部３２内に突出するようにして形成されている。
【００５０】
また、穴部５２は、図３に示すように、断面形状を略三角形状となすように形成されている。そして、この穴部５２は、図４に示すように、下辺５２ａを端子取付け板３６側である収納体３３の底面側に配置された一対の電池１₁ ，１₂ の上縁を結ぶ線Ｐ₁ に略一致させ、頂点５２ｂ側が収納体３３の底面側に配置された一対の電池１₁ ，１₂ 上に配置された上面側に配置された一対の電池１₃ ，１₄ 間に突出するようにして形成されている。このように穴部５２を形成するのは、本実施例のバッテリ装置３１が装着されるバッテリ装着部に前述した２本の電池１，１を収納した第１のバッテリ装置２を装着する場合に、穴部５２に嵌合する嵌合突部に第１のバッテリ装置２の上面に形成した誤挿入防止溝１１を係合可能とするためである。
【００５１】
さらに、穴部５２は、図２及び図４に示すように、断面方向の最大径Ｒ₁ がその深さＤ₁ より小さくなされている。すなわち、穴部５２は、開口端５２ａの径Ｒ₁ に比し深さＤ₁ を大きくしている。これは、穴部５２に相対嵌合するバッテリ装着部側に設けられる嵌合突部の長さを長尺となし、このバッテリ装着部に装着されるバッテリ装置３１の装着操作時におけるガイド機能の向上を図るためである。
【００５２】
さらにまた、穴部５２は、その深さＤ₁ を端子取付け板３６に設けられた円筒状の正極端子３７及び負極端子３８の長さＬ₁ より大きくして形成されている。これは、穴部５２に相対嵌合するバッテリ装着部側に設けられる嵌合突部の長さを、正極端子３７及び負極端子３８に相対嵌合する接続端子となる接続ピンより長尺となすことを可能となし、嵌合突部が穴部５２に嵌合し、バッテリ装置３１のバッテリ装着部に対する装着位置の位置決めが図れた後、正極端子３７及び負極端子３８の接続ピンに対する嵌合が図られるようにするためである。
【００５３】
なお、本実施例のバッテリ装置３１は、電子機器内に構成されたバッテリ装着部のみならず電子機器の外表面に設けられた外付け型のバッテリ装着部への装着を可能となすため、収納体３３の底板を構成する端子取付け板３６の相対向する両側に、図１、図２及び図５に示すように、外付け型のバッテリ装着部に設けられた係合片に相対係合する一対ずつの係合溝部５４，５５が形成されている。これら係合溝部５４，５５は、外付け型のバッテリ装着部に設けられたＬ字状の係合片に対しスライド操作することによって相対係合し得るように、図１及び図５に示すように、収納体３３の底面側に一部を開口させた略Ｌ字状に形成されている。また、収納体３３の底面５９には、図５に示すように、外付け型のバッテリ装着部の底面側に設けた弾性変位可能な係合片及び位置決め突起が相対係合する複数の位置決め穴５６，５７が設けられている。さらに、収納体３３の底面には、図５に示すように、バッテリ装着部に装着したとき、このバッテリ装着部側に設けられた移動操作部材によって移動操作され、一旦バッテリ装着部に装着されて使用されたことを表示する使用状態表示部５８が設けられている。
【００５４】
上述したように構成された本実施例のバッテリ装置３１が装着される電子機器としてのビデオカメラ６１には、図６に示すように、カメラ本体を構成する外筺６２の一部にバッテリ装着部６３が設けられている。このバッテリ装着部６３は、外筺６２の一部を筺体６４によって区画することによって構成される。バッテリ装着部６３が構成される筺体６４は、図７及び図８に示すように、バッテリ装置３１の正極端子３７及び負極端子３８の開口端３７ａ，３８ａが臨む挿入端側の端面４１に対応する挿脱口６５を備えている。この挿脱口６５は、バッテリ装置３１の挿入端側の端面４１に対応する形状に形成されている。筺体６４内に構成されるバッテリ装着部６３は、図７に示すように、バッテリ装置３１を内包するように収納するに足る大きさに形成される。
【００５５】
そして、バッテリ装着部６３の相対向する内側面６６，６７には、このバッテリ装着部６３に装着されるバッテリ装置３１の相対向する両側面６６，６７に設けた第１及び第２の溝部４４，４５が相対係合する第１及び第２の突条部６８，６９が突設されている。これら第１及び第２の突条部６８，６９は、挿脱口６５の近傍に端部を臨ませ、バッテリ装置３１の装着方向と平行に形成されている。また、第１及び第２の突条部６８，６９は、第１及び第２の溝部４４，４５の略全長に亘って係合するに足る長さをもって形成されている。
【００５６】
また、バッテリ装着部６３の相対向する内側面６６，６７に直交し、上記バッテリ装置３１の挿入方向と平行な面である上面７０には、バッテリ装置３１の上面側に設けた第３の溝部５１が相対係合する第３の突条部７１が突設されている。この第３の突条部７１も、第１及び第２の突条部６８，６９と同様に、挿脱口６５の近傍に端部を臨ませ、バッテリ装置３１の装着方向と平行に形成され、第３の溝部５１の略全長に亘って係合するに足る長さをもって形成されている。
【００５７】
さらにまた、バッテリ装着部６３のバッテリ装置３１の挿入方向と対向する内方側の端面７２には、バッテリ装置３１の挿入方向側の端面４１に設けられた穴部５２が相対嵌合する嵌合突部７３が突設されている。この嵌合突部７３は、バッテリ装置３１の穴部５２に対応する断面形状に形成されている。すなわち、嵌合突部７３は、図９に示すように、断面形状を略三角形状となすように形成されている。さらに加えて、バッテリ装着部６３のバッテリ装置３１の挿入方向と対向する内方側の端面７２には、バッテリ装置３１の挿入方向側の端面４１に開口端３７ａ，３８ａを臨ませた筒状をなす正極端子３７及び負極端子３８がそれぞれ相対嵌合して電気的に接続される接続端子を構成する接続ピン７４，７５が突設されている。そして、嵌合突部７３は、図８に示すように、その長さＬ₂ をバッテリ装置３１に設けられた正極端子３７及び負極端子３８の長さＬ₁ 及びバッテリ装着部６３側に設けられた接続ピン７４，７５の長さＬ₃ より長尺に形成されている。ここで、嵌合突部７３の長さＬ₂ は１５ｍｍとなされ、接続ピン７４，７５の長さＬ₃ は６ｍｍとなされている。なお、接続ピン７４，７５の長さＬ₃ は、嵌合突部７３の長さＬ₂ より短く、正極端子３７及び負極端子３８への正確な嵌合が図れればよく６ｍｍに限定されるものではない。同様に、嵌合突部７３の長さＬ₂ は、接続ピン７４，７５の長さＬ₃ より長尺であればよく１５ｍｍに限定されるものではない。
【００５８】
また、バッテリ装着部６３のバッテリ装置３１の挿入方向と対向する内方側の端面７２には、このバッテリ装着部６３に装着されたバッテリ装置３１によって押圧されて圧縮され、このバッテリ装置３１をバッテリ装着部６３から排出する方向に付勢する力が蓄積されるコイルバネによって形成されてたバッテリ装置排出用の弾性部材７７が設けられている。さらに、筺体６４の挿脱口６５側の一側には、挿脱口６５内に一部が突出し、バッテリ装着部６３に装着されたバッテリ装置３１を弾性部材７７の付勢力に抗してバッテリ装着部６３内に保持しておくロック部材７８が設けられている。このロック部材７８は、一側縁から突設した係止部７９を図示しない付勢部材によって係止部７９が挿脱口６５内に突設するように図７中矢印Ｇ方向に付勢されて取付けられている。ロック部材７９は、バッテリ装着部６３に挿入操作されるバッテリ装置３１によって押圧されて付勢部材の付勢力に抗して図７中反矢印Ｇ方向に移動される。そして、バッテリ装置３１がバッテリ装着部６３内に装着されると、ロック部材７９は、付勢部材の付勢力を受けて図７中矢印Ｇ方向により移動され、係止部７９によりバッテリ装置３１の他方の端面４６の一部を係止しバッテリ装着部６３内にロックする。
【００５９】
なお、ロック部材７９は、後述するように２本の電池１を収納した第１のバッテリ装置２を収納した場合にも、このバッテリ装置２をバッテリ装着部６３内にロックし得る位置に設けられる。
【００６０】
バッテリ装着部６３に装着されたバッテリ装置３１を取り出す場合には、ロック部材７９を付勢部材の付勢力に抗して図７中反矢印Ｇ方向に移動操作し、係止部７９によるロックを解除させると、バッテリ装置３１は、弾性部材７７の付勢力を受けて挿脱口６５から排出される。
【００６１】
また、筺体６４には、図７に示すように、挿脱口６５を開閉する開閉蓋８０がヒンジ部８１を介して回動可能に取付けられている。この開閉蓋８０は、バッテリ装着部６３を閉塞し、バッテリ装置３１が装着されていないときには、バッテリ装着部６３内への塵芥の進入を防止するとともに、バッテリ装置３１が装着された場合には、バッテリ装置３１のバッテリ装着部６３からの不用意な脱落を防止するものである。
【００６２】
さらにまた、バッテリ装着部６３のバッテリ装置３１の挿入方向と対向する内方側の端面７２側には、このバッテリ装着部６３に装着されるバッテリ装置３１に設けた使用状態表示部５８を移動操作する移動操作部材８２が設けられている。
【００６３】
上述したように構成されたバッテリ装着部６３に対しバッテリ装置３１を装着するには、図１０に示すように、第１及び第２の溝部４４，４５を第１及び第２の突条部６８，６９に対応させ、さらに第３の溝部５１を第３の突条部７１に対応させ、バッテリ装着部６３内の底面７６上に底面５９を沿わせた状態で、正極端子３７及び負極端子３８の開口端３７ａ，３８ａが臨まされた端面４１を挿入端として、挿脱口６５に挿入する。このとき、バッテリ装置３１は、底面７６をバッテリ装着部６３内の底面７７に沿わせるようになす。この状態からさらにバッテリ装置３１を、図１１中矢印Ｘ方向に挿入していくと、第１及び第２の溝部４４，４５が第１及び第２の突条部６８，６９が相対係合するとともに、第３の溝部５１が第３の突条部７１が相対係合する。第１、第２及び第３の溝部４４，４５及び５１が、第１、第２及び第３の突条部６８，６９及び７１に相対係合することにより、バッテリ装置３１は、図１１に示すように、バッテリ装着部６３に対する挿入姿勢及び挿入方向が規制されてバッテリ装着部６３に挿入されていく。
【００６４】
バッテリ装置３１は、第１、第２及び第３の溝部４４，４５及び５１が、第１、第２及び第３の突条部６８，６９及び７１に相対係合された状態からさらにバッテリ装着部６３の内方に向かう図１１中矢印Ｘ方向に挿入されると、図１２に示すように、穴部５２に嵌合突部７３が嵌合する。さらに、ここからさらにバッテリ装置３１が、バッテリ装着部６３の内方に向かう図１２中矢印Ｘ方向に挿入されると、図１３に示すように、正極端子３７及び負極端子３８が接続ピン７４，７５に相対嵌合し、バッテリ装着部６３への装着が完了し、ビデオカメラ６１への電気的な接続が図られ、このビデオカメラ６１への電源が供給可能な状態となる。
【００６５】
なお、バッテリ装置３１が完全にバッテリ装着部６３に装着される過程で、具体的に図示はしないが、バッテリ装置排出用の弾性部材７７が圧縮され、バッテリ装置３１をバッテリ装着部６３から排出する方向の力が蓄積される。
【００６６】
また、バッテリ装着部６３に装着されたバッテリ装置３１は、ロック部材７９の係止部７９により他方の端面４６の一部が係止されバッテリ装着部６３内にロックされる。さらに、バッテリ装着部６３にバッテリ装置３１が装着操作されると、移動操作部材８２により使用状態表示部５８が移動操作され、一度ビデオカメラ６１に装着され使用状態に置かれたことが表示される。
【００６７】
上述のようにバッテリ装着部６３に装着されたバッテリ装置３１は、両側に設けた第１及び第２の溝部４４，４５に第１、第２及び第３の突条部６８，６９が係合して支持されてなるので、バッテリ装着部６３内の移動が規制されて安定した状態で装着される。特に、４本の電池１を収納して重量が大きくなったバッテリ装置３１が安定した状態で装着されるので、このバッテリ装置３１が装着されるビデオカメラ６１に衝撃が加わったとしても、バッテリ装置３１のガタ付きによるビデオカメラ６１の損傷を確実に防止できる。
【００６８】
また、バッテリ装置３１の穴部５２に嵌合する嵌合突部７３は、前述したように、正極端子３７及び負極端子３８の長さＬ₃ 及び接続ピン７４，７５の長さＬ₄ より長尺に形成されてなるので、正極端子３７及び負極端子３８と接続ピン７４，７５との相対嵌合は、第１及び第２の溝部４４，４５に第１、第２及び第３の突条部６８，６９が係合され、且つ穴部５２への嵌合突部７３の嵌合が行われバッテリ装置３１のバッテリ装着部６３に対する位置決めが図られた後に行われる。従って、正極端子３７及び負極端子３８と接続ピン７４，７５とを正確に相対嵌合させることができるとともに、正極端子３７及び負極端子３８と接続ピン７４，７５の保護を図ることができる。
【００６９】
そして、バッテリ装置３１は、穴部５２に嵌合突部７３が嵌合されてバッテリ装着部６３に挿入されていくので、収納体３３の外周面をバッテリ装着部６３の内周面に強く摺接させることなくバッテリ装着部６３への装着操作を行うことができ、バッテリ装着部６３への挿脱の繰り返しにより、収納体３３の外周面の摩耗や擦過傷の発生を防止することができる。このとき、穴部５２は、前述したように、開口端５２ａの径Ｒ₁ に比し深さＤ₁ を大きくしているので、穴部５２に相対嵌合するバッテリ装着部６３側に設けられる嵌合突部７３の長さを長尺となし、このバッテリ装着部６３に装着されるバッテリ装置３１の装着操作時におけるガイド機能の向上が図られる。
【００７０】
さらに、上述のように構成されたバッテリ装着部６３に対して、バッテリ装置３１が上下を逆にして挿入しようとすると、第３の溝部５１と第３の突条部７１とが一致されず、この第３の突条部７１の先端がバッテリ装置３１の端面４１の一部に当接し、誤挿入を防止する。
【００７１】
さらにまた、バッテリ装置３１が挿入側の端面４１とは逆向きの他方の端面４６側からバッテリ装着部６３に挿入しようとすると、図１４に示すように、第１、第２の突条部６８，６９又は第３の突条部７１の先端面が図１４に示すように他方の端面４６に当接し、バッテリ装着部６３への挿入が規制される。すなわち、第１、第２及び第３の溝部４４，４５及び５１の他方の端面４６側を閉塞して形成することにより、これら第１、第２及び第３の溝部４４，４５及び５１は、第１、第２及び第３の突条部６８，６９及び７１と相まって誤挿入防止機構を構成する。
【００７２】
さらにまた、バッテリ装置３１が挿入側の端面４１とは逆向きの他方の端面４６を挿入端としてバッテリ装着部６３が筺体６４を押し広げて無理に挿入されたとしても、穴部５２に嵌合する嵌合突部７３が他方の端面４６に当接し、更なるバッテリ装着部６３への挿入が規制されて誤挿入を防止する。
【００７３】
上述したバッテリ装着部６３には、前述した２本の電池１，１を並列配置して収納した第１のバッテリ装置２が誤挿入を防止して装着される。この第１のバッテリ装置２を装着するには、図１５に示すように、正極端子５及び負極端子６の開口端５ａ，６ａが臨む装着方向側の端面８を挿脱口６５に対向させ、底面側をバッテリ装着部６３内の底面７６に沿わせて挿入する。このとき、第１のバッテリ装置２の上面９側の両側に形成した円弧部１０，１０が、図１６に示すように、バッテリ装着部６３の相対向する両側面６６，６７に突設された第１及び第２の突条部６８，６９の下側縁に当接して支持され、バッテリ装着部６３の底面７６からの浮き上がりが防止されて図１７中矢印Ｘ方向に挿入されていく。さらに、第１のバッテリ装置２をバッテリ装着部６３内に挿入していくと、嵌合突部７３が上面９側の誤挿入防止溝１１に係合する。このように第１及び第２の突条部６８，６９により支持され嵌合突部７３が誤挿入防止溝１１に係合することにより、第１のバッテリ装置２は、バッテリ装着部６３の底面７６上に支持された装着位置が規制されてバッテリ装着部６３に装着される。そして、嵌合突部７３が誤挿入防止溝１１に係合した状態からさらに第１のバッテリ装置２を図１８中矢印Ｘ方向に挿入していくと、正極端子５及び負極端子６が接続ピン７４，７５に相対嵌合される。このとき、第１のバッテリ装置２は、第１及び第２の突条部６８，６９並びに嵌合突部７３により支持されて正確な位置決めが図られてバッテリ装着部６３内に装着されてなるので、正極端子５及び負極端子６と接続ピン７４，７５との相対嵌合を正確に位置合わせを図って行うことができ、正極端子３７及び負極端子３８と接続ピン７４，７５の保護を図ることができる。
【００７４】
そして、上述したバッテリ装着部６３に第１のバッテリ装置２が装着方向側の端面８とは逆の誤挿入防止溝１１の開口端が設けられた端面８と逆の平坦な端面８ａ側を挿入端として、図１９に示すように挿入すると、嵌合突部７３の先端が端面８ａの一部に当接して挿入が規制されて誤挿入が防止される。
【００７５】
さらに、第１のバッテリ装置２が挿入側の端面８側から挿入された場合であっても、底面７６から離間しバッテリ装着部６３の上面７０側に位置して挿入された場合には、図２０に示すように、嵌合突部７３の先端面に当接して挿入が規制されて誤挿入が防止される。
【００７６】
さらにまた、第１のバッテリ装置２が、図２１に示すように、バッテリ装着部６３の対角線に沿うように傾斜した姿勢で挿入すると、嵌合突部７３の先端面に装着方向側の端面８又は他方の端面８ａの一部が当接して挿入が規制されて誤挿入が防止される。
【００７７】
さらにまた、第１のバッテリ装置２が、バッテリ装着部６３に対し垂直にとなされ、いずれか一方の内側面６６，６７、例えば一方の内側面６６に沿って図２２に示すように挿入されたような場合には、装着方向側の端面８又は他方の端面８ａの一部が第１及び第２の突条部６８，６９又は嵌合突部７３の先端面に当接して挿入が規制されて誤挿入が防止される。
【００７８】
ところで、上述した実施例のバッテリ装置３１の収納体３３は、端子取付け板３６上に中ケース半体３５及び上ケース半体３４を積層するように結合して形成しているが、図２３に示すように、端子取付け板３６上に高さ方向に分割された一対のケース半体１３４，１３５を設け、これらケース半体１３４，１３５を突き合わせ結合して構成してもよい。また、収納体３３は、図２４に示すように、３層に分割された下ケース半体２３３、中ケース半体２３５及び上ケース半体２３４を互いに突き合わせ結合して形成し、この収納体３３の一方の端面に正極端子３７及び負極端子３８を埋設した端子取付け板２３６を一体に取付けるようにしてもよい。これらの場合にあっても、前述したバッテリ装置３１と同様に、第１、第２及び第３の溝部４４，４５及び５１並び穴部５２が設けられる。
【００７９】
さらにまた、収納体３３は、上ケース半体３４、中ケース半体３５及び端子取付け板３６をモールド成形によって一体に形成してもよい。この場合、電池１は、成形用金型内にインサートされ、収納体３３の成形と同時にこの収納体３３内に収納される。
【００８０】
さらにまた、バッテリ装置３１及び第１のバッテリ装置２のバッテリ装着部６３への誤挿入を防止することだけを目的をする場合には、穴部５２と嵌合突部７３によって誤挿入が防止できるので、図２５に示すように、第１及び第２の溝部４４，４５を設ける必要はない。
【００８１】
さらにまた、穴部５２と嵌合突部７３によって単一のバッテリ装置のみを装着可能とするバッテリ装着部に対するバッテリ装置の誤挿入を目的とする場合には、バッテリ装置は、４本の電池１を収納したものに限定されることなく、２本若しくは４本以上を収納したものにも適用できる。
【００８２】
【発明の効果】
本発明に係るバッテリ装置は、収納体に設けた第１及び第２の溝部をこのバッテリ装置が装着されるバッテリ装着部側に設けた突条部に相対係合させて装着させることができるので、バッテリ装着部に対する装着位置の位置決めが図られて装着され、多数の電池を収納した場合でも安定してバッテリ装着部に装着させることができる。
【００８３】
また、本発明に係るバッテリ装置は、バッテリ装着部に対する誤挿入を防止するとともに、確実に電気的な接続を図って正確にバッテリ装着部に装着できるので、バッテリ装置の誤装着による電子機器に対する電源の供給不能状態を回避し、確実に電源の供給を可能となす。そして、接続端子の相対嵌合は、バッテリ装着部に対する位置決めが図られた後に行われるので、接続端子の保護を図ることができる。
【００８４】
さらに、本発明に係るバッテリ装置は、小型のバッテリ装置との互換性をもって装着可能となすバッテリ装着部を構成することができる。
【００８５】
そして、本発明に係る電子機器は、４本の電池を収納したバッテリ装置及び２本の電池を収納したバッテリ装置のいずれをも正確に位置決めし、誤挿入を防止して装着することができる。
【００８６】
さらに、本発明に係る電子機器は、バッテリ装置の挿脱を行うときに、接続端子の保護を図ることができる。
【００８７】
さらにまた、本発明に係る電子機器は、バッテリ装置とバッテリ装着部側のそれぞれの接続端子の安定した相対接続を実現し、確実な電気的な接続を実現することができる。

[0013]
  Furthermore, since the second battery device 22 is housed in the housing body 24 so that two batteries 1 are stacked one on the other, the housing efficiency of the battery 1 can be increased and the device itself can be downsized. Therefore, the battery mounting portion on the electric device side to which the battery device 22 is mounted can be reduced in size.
[0014]
[Problems to be solved by the invention]
  By the way, it is desirable that the first battery device 2 storing the two batteries 1 and the second battery device 22 storing the four batteries can be selectively mounted on a common electronic device.

In consideration of the above, it is desirable to mount the first battery device 2 containing two lightweight batteries.
[0015]
  Therefore, in order to selectively attach the first battery device 2 containing two batteries 1 and the second battery device 22 containing four batteries 1, they are provided on the video camera 12 side. As shown in FIG. 32, the battery mounting portion 25 needs to be formed in a size sufficient to accommodate the entire large second battery device 22.
[0016]
  By the way, as shown in FIG. 31, the second battery device 22 includes two batteries having a common size on the two batteries 1 and 1 arranged in parallel and having a common cylindrical size. Since 1 and 1 are stacked and stored in parallel, the end face 28 has a substantially square shape, and the end face 28 has a length S in the diagonal direction.₁ Is the width W of the first battery device 2₁ Is approximately the same. Therefore, when the small first battery device 2 is to be mounted on the battery mounting portion 25 that allows the large second battery device 22 to be mounted, the first battery device 2 is placed on the bottom surface 25 a of the battery mounting portion 25. 33 is inserted along the terminal mounting plate 7 so that the positive electrode terminal 5 and the negative electrode terminal 6 are fitted to the connection pins 17 and 18 in the battery mounting portion 25, as well as the alternate long and short dashed lines in FIG. As indicated by the dotted line, it is possible to insert the battery mounting portion 25 while being inclined in the diagonal direction. Furthermore, as shown by a broken line in FIG. 33, the first battery device 2 can be mounted on the battery mounting portion 25 with the upper surface 9 along the upper surface 25b side. In this way, when the first battery device 2 is inclined with respect to the battery mounting portion 25 or mounted while being biased toward the upper surface 25b, the positive terminal 5 and the negative terminal 6 are connected to the battery mounting portion 25 side connection pins. The relative fitting with 17, 18 is not realized. As a result, the first battery device 2 is in an erroneous mounting state in which electrical connection to the video camera cannot be achieved.
