【0001】
【発明の属する技術分野】
本発明は例えはラジオ付きテープカセットプレーヤ等の電子機器に関する。
【0002】
【従来の技術】
従来、例えば携帯用ラジオ付きテープカセットプレーヤにおいては、ラジオ等のメモリーのバックアップ等に用いられる電池が駆動電源用電池とは別個に収納されている。
【0003】
この電池はリチウム電池等の釦型電池で、電池収納部の接点端子基板上に電池をセットし、電池蓋を閉じることによって収納保持するように構成されている。
【0004】
【発明が解決しようとする課題】
ところで、このような電子機器としての携帯用ラジオ付きテープカセットプレーヤに収納される釦型電池は偏平であるため、正極、負極の判別が困難で、この電池を正極、負極を逆にして電池収納部に収納することが多くあり、このため電池をショートさせ、電池容量の低下につながる原因となっていた。
【0005】
本発明はかかる点に鑑みてなされたもので、釦型電池を収納する電子機器において、電池の逆収納を防止できるようにした電子機器を提供することを目的とする。
【0006】
【課題を解決するための手段】
上記目的を達成するために本発明は、本体部に対して蓋部が開閉可能に取り付けられ、この蓋部の内面側に釦電池を収納する電池収納部が設けられて成る電子機器において、蓋部に、電池収納部を開閉する電池蓋が起伏回動可能に取り付けられ、ここで電池蓋は、釦電池を保持する挿入保持部と、この挿入保持部に形成され、釦電池の形状に合わせて形成される挿入口と、を備えるとともに、電池蓋の回動自由端部側には、本体部に対して蓋部を閉じた状態で、電池収納部が設けられた蓋部と相対する本体部側に設けられた凹部に係合して電池蓋の開放を阻止する阻止部が設けられ、更に、本体部には飾り枠が設けられ、この飾り枠の一部に凹部が形成されている構成としたものである。
【0007】
この場合、鉛型電池の一方及び他方の主面の径は異なり、この釦型電池が逆挿入されたときこの釦型電池のより径が大きい主面側の一部が突き当たり挿入不能となるように挿入口に形成される突部を有する構造とする。
【0008】
このような構造とすることにより電池の逆収納が防止され、電池のショートによる容量低下等の不良をなくすことができる。
【0009】
【発明の実施の形態】
以下、本発明の実施例を図面を参照して説明するに、本例は、本発明をラジオ付き携帯用テープカセットプレーヤに適用した場合の一例である。
【0010】
図において、1はラジオ付き携帯用テープカセットプレーヤの全体を示し、本体部2と、記録及び/又は再生部(以下、単に記録・再生部という)3と、ラジオチューナを備えたカセット蓋部4とから構成されている。
【0011】
本体部2は、内面側がテープカセットCの収納部2aとなされ、テープ走行駆動機構としてのハブ駆動軸5a,5bとキャプスタン6a,6bとカセット位置決めピン7a,7bが配設されている。
【0012】
記録・再生部3はフレーム3aの略中央部に、記録及び/又は再生ヘッド8を取付け、このヘッド8を挟んで両側に消去ヘッド又はテープガイドを取付け、さらに、その外側、即ち、カセット収納部2aに配設されたキャプスタン6a,6bに対応するピンチローラ10a,10bを取付けて構成されており、フレーム3aはカセット収納部2aの後縁部の両側に配設されたブラケット11a,11bに支点軸12a,12bにより軸支されている。また、ブラケット11a,11bにはフレーム3aの倒伏回動時の位置決め11a1 ,11b2 を形成してある。
【0013】
この記録・再生部3のフレーム3aの両側にはカセットホルダ13a,13bが固定されている。このカセットホルダ13a,13bはアルミニウムダイカストにより成形した基体13a1 ,113b1 に、一方側の基体13a1 には正面略コ字状の保持枠13a2 を、他方側の基体13b1 には正面略L字状の保持枠13b2 を固定して構成されており、基体13a1 ,13b1 においてフレーム3aの両側面にねじ14によって固定してある。
【0014】
このカセットホルダ13a,13bの基体13a1 ,13b1 に、その外側面側の前述したフレーム3aのブラケット11a,11bに対する軸支部から所要間隔で離れた部位においてカセット蓋部4を軸着してある。
【0015】
このカセット蓋部4は上面部4aの周縁に周面部、即ち、前後面部4b,4c及び両側面部4a,4eを形成した匣体状で、両側面部4d,4eの後端部において前述したカセットホルダ13a,13bの基体13a1 ,13b1 に軸着してある。
【0016】
また、本体部2とカセット蓋体4とは互いに回動可能に連結されたリンク部材14a,14bにより一側面部の略中央部において連結されて、この本体部2とカセット蓋部4との間の開き角度を規制している。
【0017】
また、カセット蓋部4は本体部2に対して閉じた状態でロック機構15によりロックされる。このロック機構15は本体部2の前壁部側に備えられる回転ロック板16と摺動ロック板17から成るロック部材15aと、カセット蓋部4の前面部4bに固定される係合体18から成る被ロック部材15bとから構成されて、本体部2に対してカセット蓋部4を閉じることによりカセット蓋部4側の係合体18に対して本体部2側の回転ロック板16のフック部16aが上方から回転係合し、摺動ロック板17のフック部17aが横方向から摺動係合することによりロックされる。
【0018】
また、このロック解除は、本体部2の前壁部の前面側に取付けられ、摺動ロック板17に連結される摺動つまみ19を摺動操作することにより、摺動ロック板17が摺動されると共にこれに伴い回転ロック板16が回転されてロックが解除される。
【0019】
このように本体部2に取付けられるカセット蓋部4の内面側にラジオチューナ21が内蔵されている。即ち、上面部4aの内面にチューナ回路マウント基板22が固定され、この基板22をチューナカバー23により覆っている。
【0020】
そして、回路蓋部4の内面側のチューナ21の一側部に位置してラジオ等のメモリーのバックアップ等に用いられる電池の収納部24が配設されている。これに用いられる電池はリチウム電池等の偏平な釦電池25であって、電池蓋26に挿入保持させた状態で、この電池蓋26を閉じることによって釦電池25を電源回路基板27の正負接点端子28a,28bに当接させるようになっている。
【0021】
この釦電池25を挿入保持する電池蓋26は偏平状で主板部26aの基端部(後端部)側に一対の平行なアーム片29a,29bを延設して、このアーム片29a,29bをカセット蓋部4の上面部4aの内面に突設した軸支片30a,30bに軸支することによりカセット蓋部4に対して起伏可能に取付けられる。
【0022】
この電池蓋26は主板部26aの両縁部の内面側には側壁部31a,31bを形成して、この両側壁部31a,31bの端面から内方に水平に支持面部32a,32bを突設して電池挿入部26b(挿入保持部)を形成すると共に、両側壁部31a,31bの後部内面側に位置決め部31a1 ,31b1 を形成してある。
【0023】
そして、この電池蓋26における電池挿入部26bの挿入口は釦電池25の形状に合わせて形成され、即ちこの電池蓋26の両側壁部31a,31bの前部内面側、詳しくは両側壁部31a,31bのと両支持面部32a,32bとの間の内角部に突縁部33a,33bを突出形成して、釦電池25の正負反転した誤挿入を防止するようにしてある。即ち、この電池蓋26の両側壁部31a,31b間に釦電池25を、その正極面25a側を外側にして挿入しようとするときは、この正極面25a側は負極面25b側より大径であるため突縁部33a,33bに突当り挿入不能になる。
【0024】
また、この電池蓋26の回動自由端部である前端部には、カセット蓋部4の上面部4aの内面側前部に当接する当接面部34を形成し、この当接面部34から本体部面の前部にかけて所要間隔で平行のスリット35a,35bを切削して弾性部面34aを形成すると共に、この弾性部面34aをカセット蓋部4の前面部4bの内面側と対向するように延長して阻止部である爪掛部34aを形成し、この爪掛部34aに横方向に係合突縁34aを形成してあり、この係合突縁34aをカセット蓋部4の前面部4bの端縁内側に突出形成した係合片36に係合することにより電池蓋26はカセット蓋部に対して閉じた状態で保持されるようになっている。
【0025】
一方、本体部2の前壁部の端縁面、詳しくは本体部2の周縁に固定される飾り枠41の前側部41aの一側部上面に、前述した電池蓋26の弾性部面34aの爪掛部34a1 に対応して係合部42を形成してあり、本例においてはこの係合部42は凹部43により形成されるもので、この凹部43の内側縁部を爪掛部34a1 の内面側、即ち、係合突縁34a2 を形成した面と反対側の面に対応する高さに形成することにより係合部として形成してある。
【0026】
このように構成される電池蓋26はカセット蓋部4を開いた状態で弾性部面34aの爪掛部34a1 を引いて係合突縁34a2 をカセット蓋部4側の係合片36から離し、後部のアーム片29a,29bの軸支部を支点として回動することによって開かれる。この状態で内面側の両側壁部31a,31bと両支持面部32a,32bによって形成される挿入部に釦電池25を挿入する。
【0027】
この釦電池25の挿入は、前述した如く、正極面25aを電池蓋26の主板部26aの内面に摺接するように挿入する。これを逆にして挿入するときはと、大径の正極面25aの周縁が突縁部33a,33bに突当り全体の挿入が不能になり、誤挿入が防止される。
【0028】
このように、釦電池25を正常状態に挿入した電池蓋26をカセット蓋部4に対して閉じて係合片36に係合突縁34a2 に係合することにより閉じた状態で保持される。これにより釦電池25は負極面25b側が電源回路基板27の負極接点端子28bに当接されると共に正極面25aの周縁が円弧状の正極接点端子28aに当接されて正常状態でセットされる。
【0029】
このようにして、電池蓋26を閉じて釦電池25をセットした状態でカセット蓋部4を本体部2に対して閉じると、電池蓋26の爪掛部34a1 の先端部内面側、即ち、係合突縁34a2 を形成した面と反対側の面側が、本体部2の前壁部の端縁面、即ち、飾り枠41の前側部41aの一側部上面に凹部43により形成した係合部42の前面側に摺接状に対応される。
【0030】
このように、電池蓋26の爪掛部34a1 は先端部内面側が本体部2の係合部42に対応されることにより、係合突縁34a2 がカセット蓋部4側の係合片36から離れる方向への屈曲が阻止されて係合片36に対する係合突縁34a2 の係合が外れることなく、カセット蓋26を閉じた状態では電池蓋26の開放が防止される。
【0031】
従って、テーププレーヤ1を落とす等、いかなる衝撃が加わっても電池蓋26が開放することがなく、釦電池25の飛び出しが防止される。
【0032】
また、本例においてはカセット蓋部4の内面側に固定されたチューナ回路マウント基板22を覆っているチューナカバー23にはその前部に圧縮可能な弾性突起部材51が配設されている。
【0033】
この弾性突起部材51は回路蓋部4を開いたとき、カセット蓋部4の内側においてカセットホルダ13a,13bに挿入保持されているテープカセットCを押し出して傾斜状態になし、そのテープカセットCの後部とカセット蓋部4の前面部4bとの間に間隙が生じることになってテープカセットCを円滑に取り出すことができる。
【0034】
また、カセット蓋部4を閉じた状態においては弾性突起部材51は本体部2のカセット収納部2aに収納されたテープカセットCに押し潰された状態で圧着し、この弾性力及び摩擦力によるスタピライザー効果によってテープカセットCはカセット収納部2a内に安定して保持される。
【0035】
この弾性突起部材51は一例として薄肉ゴムにより略帽体状に形成し、鍔部をチューナカバー23に係合して取付けることができる。
【0036】
以上、本発明の実施例を説明したが、本発明はこの実施例の限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々変更できるものである。
【0037】
また、本発明に係る電子機器は、前述した実施例の如きラジオ付きテープカセットプレーヤのみならず、種々の電子機器、例えば、音響記録及び再生装置、ディスクプレーヤ、ビデオテープレコーダ装置、ビデオカメラ装置等として構成することができる。
【0038】
【発明の効果】
以上のように本発明の電子機器では、電池収納部を開閉する電池蓋に、釦電池を保持する挿入保持部と、この挿入保持部に形成され、釦電池の形状に合わせて形成される挿入口と、を備えた構成としたことにより、電池収納部への電池の誤挿入が確実に防止されて、電池のショートによる容量低下等の不良をなくすことができる。
また本発明の電子機器では、電池蓋の回動自由端部側に、本体部に対して蓋部を閉じた状態で、本体部側に設けられた凹部に係合して電池蓋の開放を阻止する阻止部を設けた構成としたことにより、機器を落とす等して大きな衝撃が加わった場合でも、電池蓋は開放されることなく釦電池の飛び出しが確実に防止され、釦電池の紛失等のおそれが解消されるという効果をも有する。
そして更に本発明の電子機器は、本体部に飾り枠が設けられ、この飾り枠の一部に凹部が形成されている構成としたことで、凹部用の部材を削減できることにより、部品点数の削減、更に、凹部を形成するスペースを別に設ける必要がなくなるので、主面方向の小型化を実現できる効果がある。
