Description
【０００１】
【発明の属する技術分野】
本発明は、２つの筐体を互いに重ねて構成される携帯型無線端末機に関するものである。
【０００２】
【従来の技術】
従来、２つの筐体を重ね合わせると共に互いに摺動可能に係合させて構成されるスライド式の携帯電話機が提案されている（例えば特許文献１〜４参照）。
例えば、図１２及び図１３に示すスライド式携帯電話機は、それぞれ扁平な第１筐体（８０）と第２筐体（９０）を互いに重ね合わせて摺動可能に係合させたものであって、図１２に示す伸張状態と図１３に示す収納状態の間で第２筐体（９０）を摺動させることが可能である。
図１２に示す如く、第１筐体（８０）の表面には、複数の操作キー（８１）が配列されると共に、下端部に送話部（８２）が設けられており、第２筐体（９０）の表面には、中央部にディスプレイ（９１）が配備されると共に、その下方には確定キーを含む複数の操作キー（９３）が配列され、上端部には受話部（９２）が設けられている。
【０００３】
上記スライド式携帯電話機においては、図１３に示す収納状態で第１筐体（８０）の表面にディスプレイ（９１）の画面が露出しているので、該ディスプレイ（９１）によって、着信待受け時の表示、着信時の表示、着信メールの表示などが可能である。
又、図１３に示す収納状態から第２筐体（８０）を上方に引き上げることによって、第２筐体（９０）は第１筐体（８０）に対して摺動し、図１２に示す伸張状態が設定される。該伸張状態では、第１筐体（８０）の全ての操作キー（８１）が露出するので、該操作キー（８１）を操作することによって、電話番号の入力、送信メール文章の入力などが可能となる。
【０００４】
このように、スライド式の携帯電話機によれば、折り畳み式携帯電話機と同様に、一方の筐体に操作キーを配備すると共に、他方の筐体にディスプレイを配置することが出来るので、これによってディスプレイの大型化を図ることが出来る。
然も、スライド式携帯電話機においては、一方の筐体（８０）に対して他方の筐体（９０）を摺動させるだけでキー操作面を露出させることが出来るので、折り畳み式携帯電話機における開き操作よりも操作性が良好である。

【発明が解決しようとする課題】
しかしながら、図１２に示す従来のスライド式携帯電話機においては、構造上、伸張状態にて第１筐体（８０）の操作キー（８１）と第２筐体（９０）のディスプレイ（９１）との間に一定の距離が生じることとなるので、例えば送信メールを作成する場合、使用者の視線はディスプレイ（９１）と操作キー（８１）の間を何度も往復することとなり、使用者がディスプレイ（９１）を見ながらキー操作を行なうことに疲労感を感じる問題がある。
又、ディスプレイ（９１）は、伸張状態のみならず収納状態においても露出しているので、例えば第２筐体（９０）を収納している着信待受け時などの携帯時に該携帯電話機を床面に落とした場合、ディスプレイ（９１）の画面が損傷を受ける虞があった。
【０００７】
そこで本発明の目的は、伸張状態でディスプレイから視線を大きく移動させることなくキー操作を行なうことが出来ると共に、収納状態でディスプレイの画面が損傷を受けることのない携帯型無線端末機を提供することである。
【０００８】
【課題を解決する為の手段】
本発明に係る携帯型無線端末機においては、携帯可能な本体（１）に、複数の操作キー（１１）とディスプレイ（２１）を配備して構成される。
前記本体（１）は、表面に前記複数の操作キー（１１）が配備された第１筐体（１０）と、表面に前記ディスプレイ（２１）が配備された第２筐体（２０）とを具え、両筐体（１０）（２０）は、第２筐体（２０）の表面に第１筐体（１０）の裏面を対向させて配置されると共に、リンク機構（３０）によって互いに相対移動可能に連結され、両筐体（１０）（２０）が最も小さな対向面積で重なった伸張状態と、両筐体（１０）（２０）が最も大きな対向面積で重なった収納状態との間で、伸縮動作が可能であり、伸張状態では、第２筐体（２０）のディスプレイ（２１）の全体が露出すると共に、該ディスプレイ（２１）と第１筐体（１０）の操作キー（１１）とが互いに接近した位置関係に並び、収納状態では、第２筐体（２０）のディスプレイ（２１）の大部分若しくは全体が第１筐体（１０）によって覆われる。
【０００９】
上記本発明の携帯型無線端末機において、ディスプレイ（２１）全体を露出させてキー操作を行なう場合、リンク機構（３０）の動作によって、第２筐体（２０）を第１筐体（１０）に対して伸張状態まで相対移動させることにより、ディスプレイ（２１）と操作キー（１０）は互いに接近した位置で並ぶこととなる。
従って、使用者は、ディスプレイ（２１）から視線を大きく移動させることなくキー操作を行なうことが出来る。
【００１０】
又、該携帯型無線端末機を携帯する場合、リンク機構（３０）の動作によって、第２筐体（２０）を第１筐体（１０）に対して収納状態まで相対移動させることにより、第２筐体（２０）の表面は第１筐体（１０）に覆われた状態となり、これによって、ディスプレイ（２１）の大部分若しくは全体が第１筐体（１０）によって保護されることとなる。
従って、第２筐体（２０）が収納状態にあるとき、ディスプレイ（２１）は、少なくとも第１筐体（１０）によって覆われた領域に損傷を受けることはない。
【００１１】
具体的構成において、第１筐体（１０）の表面には、第２筐体（２０）のディスプレイ（２１）とは反対側の端部に送話部（１２）が配備されると共に、第２筐体（２０）の表面には、第１筐体（１０）の操作キー（１１）とは反対側の端部に受話部（２２）が配備され、前記伸張状態において第１筐体（１０）の表面と第２筐体（２０）の表面とは１８０度よりも小さな角度を為す。
該具体的構成においては、通話時に使用者が受話部（２２）に耳を当てたとき、送話部（１２）が使用者の口元に接近することとなり、これによって、使用者は、通話時に送話部（１２）と口元との間の距離を気にすることなく通話することが出来る。
【００１２】
又、具体的構成において、前記リンク機構（３０）は、第１筐体（１０）と第２筐体（２０）を両筐体（１０）（２０）の伸縮方向にずれた２箇所で互いに連結する一対のリンク部材（３０ａ）（３０ｂ）によって構成されている。
該具体的構成においては、一対のリンク部材（３０ａ）（３０ｂ）の一方の端部と第１筐体（１０）とが互いに相対回転可能に取り付けられると共に、他方の端部と第２筐体（２０）とが互いに相対回転可能に取り付けられている。従って、リンク機構（３０）は、４節リンク機構として動作することとなり、これによって、第２筐体（２０）は、第１筐体（１０）に対して前記伸張状態と前記収納状態の間を相対移動する。
【００１３】
又、具体的構成において、第１筐体（１０）と第２筐体（２０）には、それぞれ回路基板（４１）（４２）が内蔵され、両回路基板（４１）（４２）は、フレキシブルリード（４３）によって互いに電気的に接続されており、該フレキシブルリード（４３）は、前記リンク機構（３０）を構成する一方のリンク部材（３０ｂ）の内部に収容されて、その両端部が第１筐体（１０）と第２筐体（２０）の内部へ伸びている。
【００１４】
該具体的構成において、フレキシブルリード（４３）は、リンク機構（３０）の動作に伴って弾性変形するので、繰り返し第２筐体（２０）を往復移動させても、疲労により破損することはない。又、フレキシブルリード（４３）は、リンク部材（３０ｂ）の内部に収容されているので、リンク機構（３０）の動作中に外部に露出することはなく、然も、フレキシブルリード（４３）がリンク機構（３０）の動作に伴って変形したとしても、周囲の部材と干渉することはない。
従って、支障なくリンク機構（３０）を動作させることが出来る。
【００１５】
又、具体的構成において、前記リンク機構（３０）は、第２筐体（２０）の側面に沿って形成されたスライド溝（７３）と、第１筐体（１０）に突設されて前記スライド溝（７３）に摺動可能に嵌まる係合ピン（７３）と、両筐体（１０）（２０）を互いに連結するリンク部材（３０ｂ）とから構成されている。
【００１６】
該具体的構成において、第１筐体（１０）の係合ピン（７３）は第２筐体（２０）のスライド溝（７３）に摺動可能に嵌まっており、リンク部材（３０ｂ）の一方の端部と第１筐体（１０）とが互いに相対回転可能に取り付けられると共に、他方の端部と第２筐体（２０）とが互いに相対回転可能に取り付けられている。これによって、第２筐体（２０）は、第１筐体（１０）に対して前記伸張状態と前記収納状態の間を相対移動する。
【００１７】
更に具体的な構成において、第１筐体（１０）と第２筐体（２０）には、それぞれ回路基板（４１）（４２）が内蔵され、両回路基板（４１）（４２）は、フレキシブルリード（４３）によって互いに電気的に接続されており、該フレキシブルリード（４３）は、前記リンク機構（３０）を構成するリンク部材（３０ｂ）の内部に収容されて、その両端部が第１筐体（１０）と第２筐体（２０）の内部へ伸びている。
【００１８】
該具体的構成において、フレキシブルリード（４３）は、リンク機構（３０）の動作に伴って弾性変形するので、繰り返し第２筐体（２０）を往復移動させても、疲労により破損することはない。又、フレキシブルリード（４３）は、リンク部材（３０ｂ）の内部に収容されているので、リンク機構（３０）の動作に伴って周囲の部材と干渉することはない。
従って、支障なくリンク機構（３０）を動作させることが出来る。
【００１９】
【発明の効果】
本発明に係る携帯型無線端末機によれば、伸張状態にてディスプレイから視線を大きく移動させることなくキー操作を行なうことが出来、然も、収納状態にてディスプレイの画面が大きな損傷を受けることはない。
【００２０】
【発明の実施の形態】
第１実施例
以下、本発明を携帯電話機に実施した形態につき、図面に沿って具体的に説明する。
図１の如く、本発明に係る携帯電話機の本体（１）は、扁平な第２筐体（２０）に扁平な第１筐体（１０）を重ねて構成されており、第１筐体（１０）の表面には、テンキーを含む複数の操作キー（１１）が配列されると共に、下端部には送話部（１２）が設けられている。第２筐体（２０）の表面には、中央部にディスプレイ（２１）が配備されると共に、上端部には受話部（２２）が設けられている。
又、図３に示す如く、第１筐体（１０）の上端部の両側には、後述の一対のリンク部材（３０ａ）（３０ａ）を取り付けるための一対の第１切欠き部（１３）（１３）が形成され、第２筐体（２０）の中央部の両側には一対のリンク部材（３０ａ）（３０ａ）を取り付けるための第２切欠き部（２３）（２３）が形成されている。
更に第１筐体（１０）の裏面及び第２筐体（２０）のディスプレイ（２１）の下方には、後述のリンク部材（３０ｂ）を収納するための第１収容室（１４）及び第２収容室（２４）がそれぞれ凹設されている。
【００２１】
図１及び図２に示す如く、両筐体（１０）（２０）は、第２筐体（２０）の表面に第１筐体（１０）の裏面を対向させて配置されると共に、リンク機構（３０）によって互いに相対移動可能に連結されており、該リンク機構（３０）の動作により、図１に示す両筐体（１０）（２０）が最も小さな対向面積で重なり合う伸張状態と、図２に示す両筐体（１０）（２０）が最も大きな対向面積で重なり合う収納状態との間で、伸縮動作が可能である。
【００２２】
図１及び図３に示す如く、リンク機構（３０）は、第１筐体（１０）と第２筐体（２０）を両筐体（１０）（２０）の伸縮方向にずれた２箇所で互いに連結する一対のリンク部材（３０ａ）（３０ｂ）によって構成されており、リンク部材（３０ａ）（３０ｂ）の一方の端部は、一対の第１枢軸（３１）（３１）を介して相対回転可能に第１筐体（１０）と連結されており、他方の端部は、一対の第２枢軸（３２）（３２）を介して相対回転可能に第２筐体（２０）と連結されている。
尚、前記一対の第１枢軸（３１）（３１）は、一方が第１筐体（１０）の第１切欠き部（１３）に配置されると共に、他方が第１筐体（１０）の第１収容室（１４）に配置されている。又、前記一対の第２枢軸（３２）（３２）は、一方が第２筐体（２０）の第２切欠き部（２３）に配置されると共に、他方が第２筐体（２０）の第２収容室（２４）に配置されている。
【００２３】
図１に示す如く、リンク部材（３０ａ）は、本体（１）の両側で第１筐体（１０）と第２筐体（２０）を連結しており、図６に示す如く、リンク部材（３０ｂ）は、両端部に両枢軸（３１）（３２）を具えると共に、該両端部に開口部を有する筒体に形成されており、該開口部を経てフレキシブルリード（４３）がリンク部材（３０ｂ）内部を貫通している。
【００２４】
図７に示す如く、両筐体（１０）（２０）にはそれぞれ回路基板（４１）（４２）が内蔵されており、両回路基板（４１）（４２）は、フレキシブルリード（４３）により互いに電気的に接続されている。該フレキシブルリード（４３）は、リンク部材（３０ｂ）の内部を貫通し、その両端部が両回路基板（４１）（４２）に繋がっている。
【００２５】
上記本発明に係る携帯電話機を着信待受け状態で携帯する際には、リンク機構（３０）の動作によって第２筐体（２０）を収納状態まで移動させる。これによって、図２の如く第２筐体（２０）の表面は第１筐体（１０）により覆われた状態となり、この結果、ディスプレイ（２１）の大部分が第１筐体（１０）によって保護されることとなる。
従って、収納状態において、ディスプレイ（２１）は第１筐体（１０）により覆われた領域に損傷を受けることはなく、然も、ディスプレイ（２１）の露出領域を用いて着信の表示や時刻の表示を行なうことが出来る。
【００２６】
尚、収納状態おいて、図３に示す如く、第１筐体（１０）の裏面と第２筐体（２０）の表面とは互いに密着し、リンク機構（３０）のリンク部材（３０ａ）は第１切欠き部（１３）と第２切欠き部（２３）の間に収容されると共に、リンク部材（３０ｂ）は第１収容室（１４）と第２収容室（２４）との間に収容されている。
【００２７】
又、図１の如くディスプレイ（２１）全体を露出させてキー操作を行なうときには、図３の矢印の如く収納状態にある第２筐体（２０）を斜め上方に引き上げる。これによって、図４の如くリンク部材（３０ａ）が第１切欠き部（１３）と第２切欠き部（２３）に収容された状態から起き上がると共に、リンク部材（３０ｂ）が第１収容室（１４）と第２収容室（２４）に収容された状態から起き上がる。このようなリンク機構（３０）の動作によって、第２筐体（２０）は、第１筐体（１０）に対して反時計回りに相対回転し、第１筐体（１０）から離間しながら第１筐体（１０）の上方に移動する。
【００２８】
そして、第２筐体（２０）は図１及び図５に示す如く、リンク機構（３０）の動作によって第１筐体（１０）に再び接近し、最終的に伸張状態まで移動する。この結果、第２筐体（２０）のディスプレイ（２１）の直下に第１筐体（１０）の操作キー（１１）が位置すると共に、ディスプレイ（２１）全体が露出することとなる。
従って、ディスプレイ（２１）の全体を表示に用いた場合に、使用者は、ディスプレイ（２１）から視線を大きく移動させることなくキー操作を行なうことが出来る。
【００２９】
又、伸張状態にて、第２筐体（２０）の表面と第１筐体（１０）の表面とは、１８０度よりも少し小さい角度、例えば１５０度〜１６５度程度の角度を為している。従って、着信時などの通話時に使用者が受話部（２２）を耳に当てたとき、送話部（１２）が使用者の口元に接近することとなり、この結果、使用者は、通話時に送話部（１２）と口元との間の距離を気にすることなく通話することが出来る。
【００３０】
又、図７及び図８に示す如く、フレキシブルリード（４３）はリンク部材（３０ｂ）の動作に伴って弾性変形するので、第２筐体（２０）を第１筐体（１０）に対して相対移動させた伸張状態又は収納状態においても、両筐体（１０）（２０）の電気的な接続は保持され、繰り返し第２筐体（２０）を往復移動させても、フレキシブルリード（４３）が疲労により破損することはない。
【００３１】
更に、フレキシブルリード（４３）は、中央部をリンク部材（３０ｂ）により保護されているので、前記リンク機構（３０）の動作中に外部に露出することはない。従って、フレキシブルリード（４３）が前記リンク機構（３０）の動作に伴って弾性変形する過程で周囲の部材と干渉することはない。
これによって、図３〜図５の如く支障なくリンク機構（３０）を動作させることが出来る。
【００３２】
第２実施例
図９〜図１１に示す本実施例の携帯電話機は、リンク機構（３０）の動作によって第２筐体（２０）が第１筐体（１０）に対して相対移動する構造においては上記第１実施例と異なるが、他の構造は第１実施例と同じである。以下の説明では、リンク機構（３０）の動作によって第２筐体（２０）が第１筐体（１０）に対して相対移動する構造にのみ言及し、他の構造については同じ符号を付して説明を省略する。
【００３３】
図９に示す如く、本体（２）は、扁平な第２筐体（２０）に第１筐体（１０）を重ねて構成されており、第１筐体（１０）と第２筐体（２０）はリンク機構（３０）によって相対移動可能に連結されている。
【００３４】
リンク機構（３０）は、第２筐体（２０）の側面に沿って形成された一対のスライド溝（７３）（７３）と、第１筐体（１０）に上端部の両側に形成された一対の狭持部（７１）（７１）に突設されて前記一対のスライド溝（７３）（７３）に摺動可能に嵌まる一対の係合ピン（７２）（７２）と、両筐体（１０）（２０）を互いに連結するリンク部材（３０ｂ）とから構成されており、該リンク部材（３０ｂ）の一方の端部は第１枢軸（３１）を介して相対回転可能に第１筐体（１０）に連結されており、他方の端部は第２枢軸（３２）を介して相対回転可能に第２筐体（２０）に連結されている。
尚、前記第１枢軸（３１）は第１筐体（１０）の第１収容室（５４）に配置されると共に、前記第２枢軸（３２）は第２筐体（２０）の第２収容室（２４）に配置されている。
【００３５】
図１１の如く第２筐体（２０）を伸張状態まで移動させる際には、図９に矢印で示す如く収納状態にある第２筐体（２０）を斜め上方に引き上げる。これによって、図１０の如くリンク部材（３０ｂ）が第１収容室（１４）と第２収容室（２４）に収容された状態から起き上がると共に、第２筐体（２０）の下端部が第１筐体（１０）から離間する。そして、第２筐体（２０）を更に矢印の如く上方に引き上げることにより、一対の係合ピン（７２）（７２）が一対のスライド溝（７３）（７３）上を摺動する。このようなリンク機構（３０）の動作により、狭持部（７１）にて第２筐体（２０）と第１筐体（１０）が互いに接触したまま、第２筐体（２０）は第１筐体（１０）の上方に移動する。
【００３６】
図１１に示す如く、第２筐体（２０）は、リンク機構（３０）の動作によって最終的に伸張状態まで移動することとなり、この結果、第２筐体（２０）のディスプレイ（２１）の直下に第１筐体（１０）の操作キー（１１）が位置すると共に、ディスプレイ（２１）全体が露出されることとなる。
従って、使用者は、ディスプレイ（２１）の全体に表示された情報を読み取ることが出来ると共に、ディスプレイ（２１）から視線を大きく移動させることなくキー操作を行なうことが出来る。
