Description

【０００１】
【発明の属する技術分野】
本発明は、携帯型通信端末機、たとえば、携帯電話機やＰＨＳ等の携帯型通信端末機に関するものである。
【０００２】
【従来の技術】
従来、携帯電話やＰＨＳ等においては、その本体に、電子部品が実装された基板と２次電池等の電池とを、本体の表裏面に振り分けて装着している。
【０００３】
その一構造例として、図４および図５に示すように、本体を構成する操作部１０１の裏面側に、電池１０８が収納される電池収納凹部１０１ａを形成するとともに、前記操作部１０１の表面側に、電子部品１０４が実装された基板１０９が収納される基板収納凹部１０１ｂを形成し、これらの電池収納凹部１０１ａと基板収納凹部１０１ｂとが隔壁１０２によって分離された構成が知られている。
【０００４】
そして、このような携帯型通信端末機は、前記基板収納凹部１０１ｂに、基板１０９を、その一方の面に実装された電子部品１０４を前記隔壁１０２へ向けて装着し、また、前記隔壁１０２の前記電池収納凹部１０１ａ側に、製品名や製品番号あるいは製造者名等が記載された銘板１０３を貼着した後に、この銘板１０３を覆うようにして、前記電池収納凹部１０１ａに電池１０８を装着して、組み上げられるようになっている。
【０００５】
【発明が解決しようとする課題】
ところで、このような従来の携帯型通信端末機にあっては、つぎのような改善すべき問題点が残されている。
【０００６】
すなわち、携帯型通信端末機にあっては、薄型化が要望されているが、前述した従来構造において薄型化を図るためには、基板１０９に実装されている電子部品１０４と隔壁１０２とのクリアランスを極力狭めるか、あるいは、前記隔壁１０２の厚みを薄くする方法しか残されていない。
【０００７】
しかしながら、前記電子部品１０４と隔壁１０２とのクリアランスを狭めるにも、前記電子部品１０４の実装精度や、実装高さのばらつきに等によって、制約があり、また、隔壁１０２を薄肉にするにも、成形性の面からの制約を受け、携帯型通信端末機の厚みを薄くすることが制限されるといった問題点である。
【０００８】
本発明は、このような従来の問題点に鑑みてなされたもので、簡便な構成により、全体としての厚みを小さくすることの可能な携帯型通信端末機を提供することを目的とする。
【０００９】
【課題を解決するための手段】
本発明の請求項１に記載の携帯型通信端末機は、前述した目的を達成するために、一方の面側に操作部若しくは表示部が形成され、他方の面側に電池が装着される本体を有し、この本体の他方の面側に、前記電池が装着される電池収納凹部が形成され、この電池収納凹部の反対側に、電子部品が実装された基板が装着される基板収納凹部が、隔壁を介して形成されてなり、この隔壁に、前記基板に実装された電子部品が挿入される貫通孔が形成されていると共に、前記電池収納凹部に、前記貫通孔を覆うようにして銘板が貼着され、前記銘板の、前記貫通孔と重畳させられる部位に、非粘着部が形成されていることを特徴とする。
本発明の請求項２に記載の携帯型通信端末機は、請求項１において、前記非粘着部は、薄フイルムを張り付けて形成されていることを特徴とする。

本発明の請求項４に記載の携帯型通信端末機は、請求項１において、前記非粘着部が、前記銘板に形成される粘着層を、前記貫通孔と重畳させられる部位を避けて形成することによって形成されていることを特徴とする。
本発明の請求項５に記載の携帯型通信端末機は、請求項１ないし請求項４の何れかにおいて、前記隔壁の前記基板収納凹部側に、前記隔壁の周囲を取り囲むようにリブが形成されていることを特徴とする。
本発明の請求項６に記載の携帯型通信端末機は、請求項５において、前記リブが、その端面が波形に形成されていることを特徴とする。
本発明の請求項７に記載の携帯型通信端末機は、請求項５において、前記リブが、複数の独立した突起によって構成されていることを特徴とする。
本発明の請求項８に記載の携帯型通信端末機は、請求項５ないし請求項７の何れかにおいて、前記リブの平行な部位のそれぞれに、係止爪が一体に設けられているとともに、前記基板に、前記各係止爪が嵌合係止される貫通孔が形成されていることを特徴とする。
本発明の請求項９に記載の携帯型通信端末機は、請求項５ないし請求項８の何れかにおいて、前記リブの表面に導電部を積層し、前記基板に前記電子部品を取り囲むとともに、前記導電部に接触させられる導電部を形成し、前記銘板表面に、前記リブの導電部に接触させられる導電シートを積層してなることを特徴とする。
本発明の請求項１０に記載の携帯型通信端末機は、請求項５ないし請求項９の何れかにおいて、前記本体が、入力手段が設けられた操作部と、表示手段が設けられた表示部とによって構成され、これらの操作部と表示部が、折り畳み可能に連結されていることを特徴とする。
【００１０】
【発明の実施の形態】
以下、本発明の一実施形態について図１ないし図３を参照して説明する。
【００１１】
図１において、符号１は、本実施形態が適用された携帯型通信端末機を示し、入力キー等の入力手段２が設けられた操作部３と、ディスプレイ１０が設けられた表示部１１とを備えており、これらの操作部３と表示部１１とが、ヒンジ１２によって回動可能に連結され、非使用時において、折り畳める構成となっている。
【００１２】
そして、前記操作部３は、その内部が、隔壁１３によって厚さ方向に２分割されて、表面側が、電子部品１４が実装された基板１５が装着される基板収納凹部３ｂとなされ、裏面側が、電池１７が装着される電池収納凹部３ａとなされている。
【００１３】
前記隔壁１３には、前記基板１５に実装された電子部品１４が挿入される貫通孔１９が形成されている。
そして、この隔壁１３の、前記基板収納凹部３ｂ側には、前記貫通孔１９の周囲に沿って環状のリブ２０が、図３に示すように形成されている。
【００１４】
一方、前記電池収納凹部３ａには、前記隔壁１３に形成された貫通孔１９を覆うように銘板２１が貼着されている。
そして、この銘板２１は、プラスチック薄フィルムや紙によって形成され、この銘板２１の、前記貫通孔１９と重畳させられる部位には、図２に破線で示すように、非粘着部２２が形成されている。
この非粘着部２２は、たとえば、前記銘板２１の粘着層に非粘着剤を塗布することによって形成され、あるいは、前記銘板２１に形成される粘着層を、前記貫通孔と重畳させられる部位を避けて形成することによって形成される。
また、貫通孔の大きさの薄フイルムを張り付けて、前記非粘着部２２を形成することも、さらに、剥離紙に貫通孔の大きさの切り込みを入れておき、剥離したときに貫通孔の部分のみ剥離紙が残り、前記非粘着部２２を形成するようにすることもできる。
【００１５】
このように構成された本実施形態に係わる携帯型通信端末機１は、前記基板１５を、電子部品１４側から基板収納凹部３ｂ内に挿入して、前記電子部品１４を、隔壁１３の貫通孔１９内に位置させた状態で固定し、前記隔壁１３の電池収納凹部３ａ側に、前記貫通孔１９を覆ようにして銘板２１を貼着した後に、前記電池収納凹部３ａに電池１７を装着することによって組み上げられる。
【００１６】
このようにして組み上げられた携帯型通信端末機１にあっては、前記電子部品１４が、隔壁１３の貫通孔１９内に位置させられていることにより、電子部品１４と電池１７との間隔が大幅に狭められることとなる。
そして、前記電子部品１４と電池１７と間には、薄い銘板２１が存在するのみであるから、前記隔壁１３の厚みを薄くすることなく、携帯型通信端末機１全体としての厚みを小さくすることが可能となる。
したがって、隔壁１３の薄肉化による成形上の制約を受けずに全体としての薄型化が可能となる。
【００１７】
また、前記銘板２１の前記貫通孔１９と重畳させられる部位に、非粘着部２２が形成されていることにより、この銘板２１と電子部品１４との粘着が回避され、この結果、携帯型通信端末機１の分解性が確保される。
【００１８】
そして、前記貫通孔１９を取り囲むようにしてリブ２０を設けておくことにより、貫通孔１９を形成することによる隔壁１３の強度低下を抑制し、また、前記基板１５の支持部材としての機能を確保することができる。
【００１９】
なお、前記実施形態において示した各構成部材の諸形状や寸法等は一例であって、設計要求等に基づき種々変更可能である。
たとえば、前記実施形態においては、操作部３と表示部１１とが、折り畳み可能に連結された構成の携帯型通信端末機１を示したが、操作部と表示部が一体構造である機種への適用ももちろん可能である。
【００２０】
また、前記リブ２０を図６に示すように、円弧状の波形のリブ２０ｂとしたり、図７に示すように、三角形状の波形のリブ２０ｃとすることも可能である。
さらに、図８に示すように、板状の独立した複数の突起（角形リブ２０ｄ）によってリブを構成したり、図９に示すように、ピン状の複数の突起（ピンリブ２０ｅ）によってリブを構成することも可能である。
このような構成とすることにより、リブ２０の軽量化を図ることができる。
【００２１】
また、図１０に示すように、前記リブ２０の平行な一対の部位に、係止爪２３を一体に設けるとともに、前記基板１５に、前記係止爪２３が嵌合係止される一対の爪用貫通孔２４を形成しておき、前記基板１５を操作部３に装着した状態において、前記基板１５の不要な動きを拘束するとともに、その変形を抑制して、前記基板１５のハンダクラックを防止することができる。
【００２２】
さらに、図１１に示すように、前記操作部３の表面で、前記リブ２０を取り囲む位置、および、前記リブ２０の表面に、蒸着によって導電部２７を形成し、前記基板１５の、電子部品１４を取り囲む位置に導電部２５を形成し、前記銘板２１の表面に導電シート２２ｂを積層しておき、前記リブ２０の天面に導電ゴムを塗布またはリブ２０に被せて配置するとともに、この導電ゴム２６を挟み込むようにして、前記銘板２１と基板１５を装着することによって、前記導電部２７、導電シート２２ｂ、および、前記導電ゴム２６を電気的に接続するとともに、これらによって前記電子部品１４を取り囲んでシールドを形成するようにすることもできる。
【００２３】
【発明の効果】
以上説明したように、本発明に係わる携帯型通信端末機によれば、隔壁の厚みを変更することなく電子部品と電池との間隔を狭めて、全体としての厚みを薄くすることができる。
しかも、携帯型通信端末機本体の成形性を損なうことなく薄型化を達成することができる。
