Description

【０００１】
【産業上の利用分野】
本発明は、円筒型の第１及び第２の電池を収容する電池収容室を有している電気機器に関する。
【０００２】
【従来の技術】
従来の電気機器においては、例えば、２本の電池を平行或いは一直線上に並べたり、又は、２本の電池を部品（例えば、スピーカー）等の凸部を挟んで互いに平行に並べるような電池の配置構造が知られている。
【０００３】
【発明が解決しようとする課題】
しかし、従来の技術において、２本の電池を平行或いは一直線上に並べる電池の配置構造では、電気機器の厚みを薄くするために、部品を電池部以外に配置させる必要上、電気機器全体の面積が広がってしまうという問題があった。そこで、面積を小さくするために、電池と部品とを重ねて配置することも考えられるが、この場合には、電気機器の幅が厚くなってしまうという問題も生じる。
【０００４】
また、部品等の凸部を挟んで互いに平行に並べる電池の配置構造では、電気機器の厚みや面積が大きくなることをある程度抑えることが可能となるが、部品の無い部分がデッドスペースとして残ることとなり、その結果、電気機器が大型化してしまうという問題があった。
【０００５】
更に、２本の電池を平行に並べる電池の配置構造では、電気機器全体を小さくするために、その外装を電池形状に整合させる必要上、四角形状となり、結果、握り難くなってしまうだけでなく、外観デザインの自由度に制限が課せられてしまうという問題もある。
【０００６】
本発明は、このような問題点を解決するためになされており、その目的は、電気機器内部に生じるデッドスペースが小さくなるように、電気機器の厚みや面積を小さくして全体を小型化するための、円筒型の第１及び第２の電池を収容する電池収容室を有している電気機器を提供することにある。
【０００７】
【課題を解決するための手段】
このような目的を達成するために、請求項１に記載の発明に従った電気機器は、円筒型の第１及び第２の電池を収容している電池収容室を有しており、電池収容室において第１及び第２の電池は同一平面内で夫々の長手方向と交差する方向に隣り合って配置され、しかも第１の電池の長手方向と第２の電池の長手方向とが鋭角をなすように配置されている、ことを特徴としている。
【００１０】
【作用】
請求項１に記載の発明に従った電気機器においては、円筒型の第１及び第２の電池を収容している電池収容室において第１及び第２の電池は同一平面内で夫々の長手方向と交差する方向に隣り合って配置され、しかも第１の電池の長手方向と第２の電池の長手方向とが鋭角をなすように配置されている。
【００１２】
【実施例】
以下、本発明の一実施例に係る、電池収容室を有した電気機器における電池の配置構造について、図１及び図２を参照して説明する。
図１（Ａ），（Ｂ）に示すように、本実施例に係る、電池収容室を有した電気機器における電池の配置構造は、２本の電池（即ち、第１及び第２の電池）２，４を収容する電池収容室６を有する電気機器（例えば、ＩＣ等の半導体メモリを使用した小型の固体録音機）に適用されており、上記２本の電池（第１及び第２の電池）２，４の長手方向Ｄ２，Ｄ４のなす角θ（図２参照）が鋭角となるように構成されている。
【００１３】
本実施例の電池の配置構造が適用された小型の固体録音機は、中枠８を挟んで取り付けられた上ケース１０及び下ケース１２を備えており、液晶表示部アセンブリ１４と電池収容室アセンブリ１６とから構成されている。
【００１４】
液晶表示部アセンブリ１４には、その上ケース１０に、例えば所定の画像情報を液晶表示する液晶表示部１８が設けられている。一方、電池収容室アセンブリ１６には、例えば所定の音声情報を出力するスピーカー２０が内蔵されており、かかる電池収容室アセンブリ１６の上ケース１０には、スピーカー２０を保護すると共に音声情報を外方に効率よく流出させるための複数の孔２２が形成された保護部２４が設けられている。
【００１５】
また、電池収容室アセンブリ１６には、その内部に第１及び第２の電池２，４を同時に収容する電池収容室６が設けられている。更に、電池収容室アセンブリ１６には、電池収容室６に第１及び第２の電池２，４を挿入し且つ収容されている第１及び第２の電池２，４を取り出す際に、開閉する電池フタ２６が開閉自在に取り付けられている。
【００１６】
電池フタ２６は、その一端がヒンジ部２８を介して電池収容室アセンブリ１６に開閉自在に取り付けられており、その他端には、電池収容室アセンブリ１６から突出した第１の係合部３０に係合可能な第２の係合部３２が設けられている。従って、このような電池フタ２６をヒンジ部２８を介して電池収容室アセンブリ１６方向に回動させて、その第２の係合部３２を第１の係合部３０に係合させることによって、電池フタ２６が電池収容室アセンブリ１６に係合し、電池収容室６を閉鎖させる。
【００１７】
また、電池フタ２６には、電池収容室６に収容された第１及び第２の電池２，４を同時に弾性保持するクリック機構が設けられており、このクリック機構は、電池収容室６に収容された第１及び第２の電池２，４の一端面を押圧可能に構成された１本の電池接片３４と、この電池接片３４に嵌め込まれ且つ電池接片３４を第１及び第２の電池２，４の一端面方向に付勢するクリックバネ３６とを備えている。
【００１８】
このような電池フタ２６によって開閉される電池収容室６内には、第１及び第２の電池２，４の一端面とは反対側の他端面を付勢する付勢バネ３８，４０が設けられている。このため、電池収容室６に第１及び第２の電池２，４を挿入した後、電池フタ２６を閉じたとき、第１及び第２の電池２，４は、その一端面が上記クリック機構によって付勢され、且つ、その他端面が上記付勢バネ３８，４０によって付勢される。この結果、第１及び第２の電池２，４は、クリック機構と付勢バネ３８，４０とによって電池収容室６内に弾性挟持されることになる。
【００１９】
なお、電池接片３４には、第１及び第２の電池２，４の一端面（同図では、第１の電池２のマイナス極端子２ａ、第２の電池４のプラス極端子４ａ）に圧接する第１及び第２の圧接部３４ａ，３４ｂが形成されており、これら第１及び第２の圧接部３４ａ，３４ｂは、第１及び第２の電池２，４の長手方向Ｄ２，Ｄ４（図２参照）に沿った方向に突出している。同様に、付勢バネ３８，４０も第１及び第２の電池２，４の他端面（同図では、第１の電池２のプラス極端子２ｂ、第２の電池４のマイナス極端子４ｂ）を長手方向Ｄ２，Ｄ４（図２参照）に沿って付勢するように配置されている。従って、第１及び第２の電池２，４は、クリック機構と付勢バネ３８，４０とによって、後述する角度θ（図２参照）なる関係に精度良く弾性挟持されることになる。
【００２０】
また、本実施例の電池の配置構造が適用された電池収容室６には、以下のような構成上の特徴を有する。
即ち、電気機器（小型の固体録音機）の電池（第１及び第２の電池）２，４が配置される箇所（即ち、電池収容室）６に対応する外装体部分（電池収容室アセンブリ１６の部分）が、電気機器（小型の固体録音機）の握り部４２を形成するように構成されている。
【００２１】
また、電気機器（小型の固体録音機）に配置される電池（第１及び第２の電池）２，４の間隔の広い側の隙間４４に、部品（スピーカーマグネット部４６）が配置されるように構成されている。
【００２２】
更に、２本の電池（第１及び第２の電池）２，４の長手方向Ｄ２，Ｄ４のなす角θ（図２参照）が、電気機器（小型の固体録音機）から２本の電池（第１及び第２の電池）２，４を同時にスライドさせて取り出し可能な角度となるように構成されている。
【００２３】
図１（Ａ）及び図２に示すように、電池収容室６は、スピーカーマグネット部４６を避けるように、第１の電池２に対して角度θだけ傾斜させて第２の電池４が収容されるように構成されている。
【００２４】
具体的には、第２の電池４は、電池フタ２６側から液晶表示部アセンブリ１４側に向かうに従って、第１の電池２から徐々に離間するように収容配置される。この場合、第１及び第２の電池２，４は、その電池フタ２６側で最も間隔が狭くなり且つその液晶表示部アセンブリ１４側で最も間隔が広くなっている。
【００２５】
このような収容配置において、第１及び第２の電池２，４は、その間隔の広い側の隙間４４にスピーカーマグネット部４６を挟むように且つ上ケース１０及び下ケース１２に平行に配置される。
【００２６】
この結果、固体録音機の厚みを抑えることが可能となる。更に、第２の電池４を斜めに収容配置させることによりスピーカーマグネット部４６以外のデッドスペースを少なくすることが可能となり、固体録音機の小型化が達成される。同時に、握り部４２を第２の電池４の配置状態に整合させて斜めに形成したことにより握り部４２を握って固体録音機を操作する際の操作性を向上させることが可能となる。
【００２７】
また、電池収容室６には、第１及び第２の電池２，４の長手方向Ｄ２，Ｄ４のなす角がθとなるように、第１及び第２の電池２，４の間に仕切り壁４８が設けられている。
【００２８】
この仕切り壁４８となす角θとの関係は、図２に示すように、仕切り壁４８の電池フタ２６（図１参照）側の端面４８ａの幅をｂ，この端面４８ａから第１の電池２のプラス極端面２ｃまでに相当する距離をａとすると、
θ≦ｔａｎ^-1（ｂ／ａ）
を満足している。この結果、電池収容室６に収容された第１及び第２の電池２，４を同時に取り出すことが可能な電池配置となる。
【００２９】
次に、本発明の一実施例に係る電池の配置構造の作用について、簡単に説明する。
まず、空の電池収容室６に第１及び第２の電池２，４を挿入する場合、第１及び第２の係合部３０，３２の係合状態を解除させた後、電池フタ２６をヒンジ部２８を介して開く。
【００３０】
この後、第１の電池２をプラス極端子２ｂ側から、第２の電池４をマイナス極端子４ｂ側から電池収容室６に挿入する。
そして、電池フタ２６をヒンジ部２８を介して回動し、第１及び第２の係合部３０，３２を互いに係合させる。
【００３１】
この結果、第１及び第２の電池２，４は、仕切り壁４８によって長手方向Ｄ２，Ｄ４のなす角がθ（図２参照）となるように位置決め配置された状態で、クリック機構と付勢バネ３８，４０とによって電池収容室６内に弾性挟持される。
【００３２】
また、電池収容室６から第１及び第２の電池２，４を取り出す場合、電池フタ２６を開くことによって、第１及び第２の電池２，４は同時に取り出される。
次に、本発明の一実施例に係る電池の配置構造の効果について説明する。
【００３３】
第１及び第２の電池２，４をその間隔の広い側の隙間４４にスピーカーマグネット部４６を挟むように且つ上ケース１０及び下ケース１２に平行に配置させたことによって、固体録音機の厚みを抑えることができる。更に、第２の電池４を斜めに収容配置させることによりスピーカーマグネット部４６以外のデッドスペースを少なくすることができ、固体録音機の小型化が達成される。同時に、握り部４２を第２の電池４の配置状態に整合させて斜めに形成したことにより握り部４２を握って固体録音機を操作する際の操作性を向上させることができる。
【００３４】
なお、本発明は、上述した実施例の構成に限定されることはなく、例えば、基板や背の高い電気部品や外装体（いずれも図示しない）を固定するためのリブ等を挟み込む電池の配置構造や、複数本の電池を斜め挿入したり２本の電池の双方を略Ｖ字状に斜め挿入する電池の配置構造も本実施例の適用範囲となる。なお、２本以上の電池を配置する例としては、複数の電池を扇状に配置させる構造や、４個の電池を２個ずつ直列に配置しそれらに所定の角度を持たせる構造も適用範囲となる。
【００３５】
また、電池は、固体録音機からスライドさせて取り出せるようになっている必要はなく、摘み出せるようになっていてもよい。具体的には、図３に示すように、固体録音機の端部側に設けられた電池収容室６から第１及び第２の電池２，４を摘み出せるように、仕切り壁４８の一部（同図では仕切り壁４８の液晶表示部アセンブリ１４側の部分）に凹部４８ｂが形成されている。このような構成によれば、かかる凹部４８ｂに指を入れることによって、第１及び第２の電池２，４を容易に摘み出すことが可能となる。この場合、第１の電池２は、そのマイナス極端子２ａが付勢バネ５０によって付勢され、且つ、そのプラス極端子２ｂが押圧部材５２に圧接されている。一方、第２の電池４は、そのプラス極端子４ａが付勢バネ５４によって付勢され、且つ、そのマイナス極端子４ｂが押圧部材５６に圧接されている。なお、図３のような構成では、第１及び第２の電池２，４は、固体録音機の中央部に配置しても構わない。
【００３６】
更に、上記具体的な実施例から次のような構成の技術的思想が導き出され、以下のような効果を奏する。
即ち、本電気機器（小型の固体録音機）は、円筒型の第１及び第２の電池（第１及び第２の電池２，４）を収容している電池収容室（電池収容室６）を有しており、電池収容室（電池収容室６）において第１及び第２の電池（第１及び第２の電池２，４）は同一平面内で夫々の長手方向（Ｄ２，Ｄ４）と交差する方向に隣り合って配置され、しかも第１の電池（第１の電池２）の長手方向（Ｄ２）と第２の電池（第１の電池４）の長手方向（Ｄ４）とが鋭角（θ）をなすように配置されている。この場合、電気機器（小型の固体録音機）内部に生じるデッドスペースが小さくなるように、電気機器（小型の固体録音機）の厚みや面積を小さくして全体を小型化させることができるという効果を奏する。
【００３７】
また、本電気機器（小型の固体録音機）は、外装体（上ケース１０及び下ケース１２）において、電池収容室（電池収容室６）に対応する部分が電気機器（小型の固体録音機）の握り部（握り部４２）を形成している。この場合、握り部（握り部４２）を握って電気機器（小型の固体録音機）を操作する際の操作性を向上させることができるという効果を奏する。
【００３８】
また本電気機器（小型の固体録音機）は、第１の電池（第１の電池２）の一端と第１の電池（第１の電池２）の一端に隣り合う第２の電池（第２の電池４）の一端との間の隙間と、第１の電池（第１の電池２）の他端と第１の電池（第１の電池２）の他端に隣り合う第２の電池（第２の電池４）の他端との間の隙間と、の内で広い側の隙間（間隔の広い側の隙間４４）に部品（スピーカーマグネット部４６）が配置されている。この場合、電気機器内部（小型の固体録音機）に生じるデッドスペースが小さくなるように、電気機器（小型の固体録音機）の厚みを抑えることができるという効果を奏する。
【００３９】
また本電気機器（小型の固体録音機）は、電池収容室（電池収容室６）において第１の電池（第１の電池２）の長手方向（Ｄ２）と第２の電池（第２の電池４）の長手方向（Ｄ４）とのなす角度（θ）が、第１の電池（第１の電池２）の一端と第１の電池（第１の電池２）の一端に隣り合う第２の電池（第２の電池４）の一端との間の隙間と、第１の電池（第１の電池２）の他端と第１の電池（第１の電池２）の他端に隣り合う第２の電池（第２の電池４）の他端との間の隙間と、の内で狭い方の隙間の側に対応する第１及び第２の電池（第１及び第２の電池２及び４）の夫々の一端又は他端を先頭にして第１及び第２の電池（第１及び第２の電池２及び４）を夫々の長手方向（Ｄ２及びＤ４）に沿い電池収容室（電池収容室６）からスライドにより取り出し可能にする角度である。この場合、電気機器（小型の固体録音機）の電池収容室（電池収容室６）内の第１及び第２の電池（第１及び第２の電池２及び４）を第１の電池（第１の電池２）の一端と第１の電池（第１の電池２）の一端に隣り合う第２の電池（第２の電池４）の一端との間の隙間と、第１の電池（第１の電池２）の他端と第１の電池（第１の電池２）の他端に隣り合う第２の電池（第２の電池４）の他端との間の隙間と、の内で狭い方の隙間の側に対応する第１及び第２の電池（第１及び第２の電池２及び４）の夫々の一端又は他端を先頭にして夫々の長手方向（Ｄ２及びＤ４）に沿い電池収容室（電池収容室６）からスライドさせて取り出すことができるという効果を奏する。
【００４３】
また、本電気機器（小型の固体録音機）は、電池収納室（電池収納室６）中に収納されている第１の電池（第１の電池２）の長手方向（Ｄ２）と第２の電池（第２の電池４）の長手方向（Ｄ４）とのなす角（θ）が、第１の電池（第１の電池２）と第２の電池（第２の電池４）の間に設けられた仕切り壁（仕切り壁４８）との関係において、仕切り壁（仕切り壁４８）の幅が狭い方の一端面（４８ａ）の幅をｂ、この一端面（４８ａ）から仕切り壁（仕切り壁４８）の幅が広い方に離れている第１の電池（第１の電池２）の端面（プラス極端面２ｃ）までに相当する距離をａとすると、θ≦ｔａｎ^-1（ｂ／ａ）なる関係を満足していれば、電気機器（小型の固体録音機）の電池収納室（電池収納室６）中の第１及び第２の電池（第１の電池２及び第２の電池４）を、仕切り壁（仕切り壁４８）の幅が狭い方から同時に取り出すことができるという効果を奏する。
