Description

【0001】
【発明の属する技術分野】
本発明は、操作ボタンを備えた操作ボタン側筺体と、表示部を備えた表示部側筺体とからなり、操作ボタン側筺体に対して表示部側筺体を展開または折り畳み自在とした折り畳み式携帯電話機に関する。
【0002】
【従来の技術】
この種の折り畳み式携帯電話機は、通話時には受話部と送話部とを耳と口とにそれぞれ対応させるために、操作ボタン側筺体から表示部側筺体を展開させ、一方、移動時等には、操作ボタン側筺体に対して表示部側筺体を折り畳むようにしている。このように、折り畳み式携帯電話機は、折り畳むことによって他の携帯電話に比べて小型化されるので携帯性に優れているといった反面、通話するには操作ボタン側筺体に対して表示部側筺体を展開させてからでないとできないため、操作性が悪いといった欠点を有していた。
【0003】
図5は従来の折り畳み式携帯電話機を示し、同図(a)は正面図、同図(b)は折り畳んだ状態を示す正面図である。これらの図において、符号20で示すものは、折り畳み式携帯電話機であって、この折り畳み式携帯電話機20は、ダイヤルや機能ボタン等の操作ボタン4が設けられた操作ボタン側筺体2と、液晶によって表示される表示部7を備えた表示部側筺体3とによって構成されている。5は操作ボタン側筐体2の下端部に設けられた送話部、8は表示部側筐体3の上端部に設けられた受話部、9はアンテナである。
【0004】
表示部側筐体3は、ヒンジ10を介して操作ボタン側筐体2に枢支されており、操作ボタン側筐体2に対して展開および折り畳み自在になっている。したがって、通話時には、同図(a)に示すように、表示部側筐体3を操作ボタン側筐体2に対して展開して使用し、移動時には、同図(b)に示すように、操作ボタン側筐体2に対して表示部側筐体3を折り畳んで持ち運んでいた。
【0005】
【発明が解決しようとする課題】
しかしながら、上述した従来の折り畳み式携帯電話機20においては、図5(b)に示すように、操作ボタン側筐体2に対して表示部側筐体3が折り畳まれた状態では、表示部側筐体3の操作ボタン側筐体2との突き合わせ部に指等が掛けられる突起等を特別に設けていない。したがって、着信時、操作ボタン側筐体2に折り畳まれた表示部側筐体3を展開しようとするときに、同図(c)に示すように、右手12Aで操作ボタン側筐体2を把持し、左手12Bで表示部側筐体3を把持して行っていた。このように、表示部側筐体3を展開するのに常に両手を必要とするから操作性が悪く、このため、着信時、呼び出し音が鳴動してから通話を開始するまでに時間がかかるといった問題があった。また、一方の手がふさがっているときには、着信に対する通話動作だけでなく、発信することすら困難となり、使い勝手が低下するという問題もあった。
【0006】
本発明は上記した従来の問題に鑑みなされたものであり、その目的とするところは、使い勝手を向上させた折り畳み式携帯電話機を提供することにある。
【0007】
【課題を解決するための手段】
この目的を達成するために、請求項1に係る発明は、操作ボタンを備えた操作ボタン側筺体と、この操作ボタン側筺体に枢支され表示部を備えた表示部側筺体とからなり、前記操作ボタン側筺体に前記表示部側筺体を展開または折り畳み自在とした折り畳み式携帯電話機において、前記表示部側筺体の幅の一部を前記操作ボタン側筺体の幅よりも大きく形成したものである。
したがって、表示部側筺体の一部を指で掛けることにより、表示部側筺体を操作ボタン側筺体に対して展開することができる。
【0008】
また、請求項2に係る発明は、請求項1に係る発明において、前記表示部側筺体の両側部の幅の一部を前記操作ボタン側筺体の両側部から突出するように形成したものである。
したがって、左右のどちらの手で操作ボタン側筺体を把持しても、指を表示部側筺体の一部に容易に掛けることができる。
【0011】
【発明の実施の形態】
以下、本発明の実施の形態を図を用いて説明する。図1は本発明に係る折り畳み式携帯電話機を示し、同図(a)は表示部側筺体を展開して示す正面図、同図(b)は表示部側筺体を折り畳んだ状態を示す底面図である。図2は同じく使用状態を示すもので、同図(a)は表示部側筺体を開き始めた状態を示し、同図(b)は表示部側筺体を展開した状態を示す。これらの図において、上述した図5に示す従来技術において説明した同一または同等の部材については、同一の符号を付し詳細な説明は適宜省略する。
【0012】
図1に示すように、本発明の特徴とするところは、表示部側筺体3の幅B1を操作ボタン側筺体2の幅Bよりも大きく形成し、同図(b)に示すように、表示部側筺体3の両側部に、操作ボタン側筺体2の両側部から突出する突出部3a,3bを設けた点にある。
【0013】
このように構成することにより、図2に示すように、着信時、利用者が利き手である右手12で操作ボタン側筺体2を把持した場合、同図(a)に示すように、右手12Aの中指を表示部側筺体3の一方の突出部3aに掛け、この突出部3aを押し上げることにより、表示部側筺体3を操作ボタン側筺体2から開く。さらに、同図(b)に示すように、右手12Aの親指で表示部側筺体3を開くことにより展開することができる。このように、着信時、操作ボタン側筺体3を把持した手と同じ手の指で表示部側筺体3を展開することができることにより、片手で展開することができるので操作性が向上する。このため、呼び出し音が鳴動してから通話を開始するまでの時間が短縮できるというだけでなく、着信時および発信時に、一方の手がふさがっているときにも、着信時の通話動作および発信動作が可能となるので、使い勝手が向上する。
【0014】
しかも、突出部3a,3bが操作ボタン側筺体2の両側部から突出していることにより、中指と表示部側筺体3を挟んで反対側の親指を他方の突出部3bに掛けることができる。また、仮に、利用者の利き手が左で、着信時、左手で操作ボタン側筺体2を把持したとしても、右手と同様に左手の中指で表示部側筺体3を開くことができるので、使い勝手が向上する。
【0015】
また、本発明の別の特徴とするところは、表示部側筺体3の幅B1を操作ボタン側筺体2の幅Bよりも大きく形成したことにより、図1(a)に示すように、表示部7の幅Bも大きくすることができ、操作ボタン側筺体2の幅Bと同一に形成した点にある。これは、表示部側筺体3においては、上端部に受話部8が設けられ、この受話部8に対応して図示を省略したスピーカが設けられていることから、表示部7の高さTを大きくすることに自ずと限界があるといった携帯電話機特有の課題に起因するものである。すなわち、表示部7の幅Bを大きくすることにより、表示部7の表面積も大きく形成することができるので、表示部7に表示される情報量が増大するだけでなく、表示される文字を大きくすることができるから、利用者へのサービスの向上を図ることができる。
【0016】
図3は本発明の第2の実施の形態を示し、同図(a)は表示部側筺体を展開して示す正面図、同図(b)は表示部側筺体を折り畳んだ状態を示す底面図である。
この第2の実施の形態では、同図(b)に示すように、操作ボタン側筺体2の側部から突出する突出部3bが、表示部側筺体3の一方の側部のみに設けられている点が、上述した第1の実施の形態と異なる点である。このように構成することによっても、着信時および発信時に、この突出部3bに操作ボタン側筺体2を把持した手の指を掛けることができるから、片手で着信および発信動作を行うことができる。
【0017】
図4は本発明の第3の実施の形態を示し、同図(a)は表示部側筺体を展開して示す正面図、同図(b)は表示部側筺体を折り畳んだ状態を示す底面図である。
この第3の実施の形態では、操作ボタン側筺体2の両側部に一対の凹部2a,2aが設けられている点に特徴を有する。こうすることにより、同図(b)に示すように、表示部側筺体3を折り畳むと、表示部側筺体3の凹部2aに対応した部位に、指を掛けることができるので、片手で表示部側筺体3を展開することができる。なお、操作ボタン側筺体2の両側部に凹部2a,2aが設けることなく、表示部側筺体3の両側部の一部に指が掛けられる突起を設けてもよい。
【0018】
【発明の効果】
以上説明したように、請求項1に係る発明によれば、着信時および発信時に操作ボタン側筺体を把持した手と同じ手の指で表示部側筺体を展開することができるので、着信時および発進時における操作を片手で行うことができ、操作性が向上する。したがって、着信時、呼び出し音が鳴動してから表示部側筐体を展開して通話を開始するまでの時間が短縮できるだけでなく、一方の手がふさがっているときにも、着信、発信が可能となるので、使い勝手が向上する。
【0019】
また、請求項2に係る発明によれば、どちらの手で操作ボタン側筺体を把持しても容易に表示部側筺体を展開することができるので、使い勝手が向上する。
