Abstract

<P>PROBLEM TO BE SOLVED: To provide a portable terminal with a camera which can open or close a lens cover without bringing into contact with the cover. <P>SOLUTION: The portable terminal with the camera includes the lens cover 12 with which a lens 2 and a mirror 3 of the camera are covered, and an opening/closing drive mechanism 13 for exposing the lens 2 and the mirror 3 to move the lens cover 12 substantially in parallel with the surface on which the lens 2 and the mirror 3 are disposed. Thus, since the cover 12 is moved without bringing into contact with the cover 12, the beauty of the terminal with the camera can be improved by limiting the size of the cover 12 to the minimum limit. Since the cover 12 is moved without bringing into contact with the cover 12, it prevents a finger from being brought into contact with the lens 2 disposed at substantially the same position as the cover 12 by mistake, and possibility of soiling the lens 2 can be eliminated. <P>COPYRIGHT: (C)2004,JPO

【０００１】
【発明の属する技術分野】
本発明は、カメラのレンズカバーを備えたカメラ付き携帯端末に関するものである。
【０００２】
【従来の技術】
近年、携帯電話、ＰＨＳ（簡易型携帯電話）等の小型の携帯端末の中には、所望時にカメラ撮影し得るよう携帯端末本体にカメラを備えたものがある。カメラを備えた携帯端末は、レンズの近傍に位置するよう携帯端末本体に形成されるスライド溝と、スライド溝に沿って移動可能なレンズカバーとを備えており、このようなカメラを使用する場合には、レンズカバーを手動で直接スライドさせてレンズを露出させることにより撮影可能な状態にし、カメラを使用しない場合には、レンズカバーを逆方向へ手動で直接スライドさせてレンズを覆い隠すことによりレンズを保護する状態にしている。
【０００３】
【発明が解決しようとする課題】
しかしながら、カメラを使用する際にレンズカバーを手動で直接開閉するよう構成すると、指で押える面積がレンズカバーに必要になるため、レンズカバーの面積が大きくなって美観が低下するという問題がある。又、レンズカバーを指で押えて移動させるため、レンズカバーと略同じ位置にあるレンズに誤って指が接触し、レンズを汚す虞れがある。
【０００４】
本発明は、斯かる実情に鑑み、レンズカバーに触れることなくレンズカバーを開閉し得るカメラ付き携帯端末を提供しようとするものである。
【０００５】
【課題を解決するための手段】
本発明の請求項１は、カメラのレンズとミラーを共に覆うレンズカバーと、前記レンズとミラーが配置された面に対しレンズカバーを略平行移動させてレンズとミラーを露出させる開閉駆動機構とを備えたことを特徴とするカメラ付き携帯端末、にかかるものである。
【０００６】
本発明の請求項２は、前記開閉駆動機構が、回転支持軸により支持されてレンズカバーに係合するアーム部を備え、前記回転支持軸を支点とするアーム部の揺動によりレンズカバーを移動させるよう構成した請求項１記載のカメラ付き携帯端末、にかかるものである。
【０００７】
本発明の請求項３は、前記アーム部に係合される開閉操作部を備え、開閉操作部を手動で移動させるよう構成した請求項２記載のカメラ付き携帯端末、にかかるものである。
【０００８】

【００１０】
本発明の請求項６は、前記アーム部より突出する凸部と、該凸部に接するよう延在部を形成するスプリングとを備え、前記スプリングは、延在部を閉止側延在部と開放側延在部に分けるよう屈曲点を形成し、前記凸部が屈曲点を超えることにより開閉操作部及びアーム部が余勢されるよう構成された請求項２〜５のいずれかに記載のカメラ付き携帯端末、にかかるものである。
【００１１】
本発明の請求項７は、カメラのレンズを覆うレンズカバーを移動させてレンズを露出させる開閉駆動機構が、回転支持軸により支持されてレンズカバーに係合するアーム部と、該アーム部より突出する凸部と、該凸部に接するよう延在部を形成するスプリングと、前記アーム部に係合させる開閉操作部とを備え、前記スプリングは、延在部を閉止側延在部と開放側延在部に分けるよう屈曲点を形成し、前記凸部が屈曲点を超えることにより開閉操作部及びアーム部が余勢されるよう構成されたことを特徴とするカメラ付き携帯端末、にかかるものである。
【００１２】
カメラを使用する際には、レンズとミラーが配置された面に対しレンズカバーを開閉駆動機構により略平行移動させてレンズとミラーを露出し、カメラを使用しない場合には、レンズとミラーが配置された面に対しレンズカバーを開閉駆動機構により逆方向へ略平行移動させてレンズ及びミラーを覆い隠す。
【００１３】
このように、本発明の請求項１又は請求項２によれば、開閉駆動機構によりレンズカバーに触れることなくレンズカバーを略平行移動させるので、薄型且つレンズカバーの大きさを最小限にして全体の美観を向上させることができる。又、レンズカバーに触れることなくレンズカバーを移動させるので、レンズカバーと略同じ位置にあるレンズに誤って指が接触することを防止し、レンズを汚す虞れを無くすことができる。
【００１４】
本発明の請求項３に示す如く、前記アーム部に係合される開閉操作部を備え、開閉操作部を手動で移動させるよう構成すると、開閉操作部を手動で移動させることによりアーム部を介してレンズカバーを移動させるので、レンズカバーの移動を簡単な構成で為し、結果的に製造コストを低減することができる。
【００１５】
本発明の請求項４に示す如く、前記アーム部を支持する回転支持軸を、前記アーム部の開閉操作部寄りに配置し、開閉操作部の移動量に対してレンズカバーの移動量を大きくするよう構成すると、開閉操作部を僅かに移動させることによりレンズカバーを大きく移動させるので、開閉操作部の移動範囲を小さくして開閉操作部の必要な範囲を低減し、全体の美観を一層向上させることができる。又、開閉操作部を僅かに移動させてレンズカバーを開閉し得るので、レンズに誤って指が接触することを防止し、レンズを汚す虞れを確実に無くすことができる。
【００１６】
本発明の請求項５に示す如く、前記レンズカバーを所定位置に停止させる停止ガイド部と、前記レンズカバーの移動を制御する制御ガイド部とを備えると、レンズカバーの誤った位置への停止を防止すると共にレンズカバーの誤った動作を防止するので、レンズカバーの開閉を確実に行うことができる。
【００１７】

【００１８】
本発明の請求項７に示す如く、カメラのレンズを覆うレンズカバーを移動させてレンズを露出させる開閉駆動機構が、回転支持軸により支持されてレンズカバーに係合するアーム部と、該アーム部より突出する凸部と、該凸部に接するよう延在部を形成するスプリングと、前記アーム部に係合させる開閉操作部とを備え、前記スプリングは、延在部を閉止側延在部と開放側延在部に分けるよう屈曲点を形成し、前記凸部が屈曲点を超えることにより開閉操作部及びアーム部が余勢されるよう構成されると、凸部が屈曲点を超えることによってスプリングが開閉操作部及びアーム部を開放側もしくは閉止側へ余勢するので、開閉操作部の移動及びレンズカバーの開閉を容易に行うことができる。又、凸部がスプリングの屈曲点を超えた場合には、開閉操作部を僅かに移動させることによってスプリングの余勢によりレンズカバーを開閉し得るので、レンズに誤って指が接触することを防止し、レンズを汚す虞れを一層確実に無くすことができる。
【００１９】
【発明の実施の形態】
以下本発明の実施の形態を図示例と共に説明する。
【００２０】
図１〜図７は本発明を実施する形態の一例である。
【００２１】
本発明のカメラ付き携帯端末１は、カメラのレンズ２及びミラー３と共に画面表示部４を備える筺体表示部５と、入力キー６を備える筺体操作部７とで構成される折り畳みタイプであり、筺体表示部５に備えられるレンズ２及びミラー３は、互いに隣接するよう一枚の設置盤８の表面に設けられており、設置盤８は、筺体表示部５の外側ケース９と内側ケース１０に挟み込まれることによって筺体表示部５の内部に配置され、外側ケース９に所定の開放窓１１を形成することによりレンズ２及びミラー３を外部へ露出している。ここで、ミラー３は、カメラで自分自身を撮影する際に自分自身がどのような状態で撮影されるか確認するためのものである。
【００２２】
設置盤８には、筺体表示部５の内側でレンズ２及びミラー３を覆い得るよう外側ケース９の開放窓１１より一回り大きいレンズカバー１２を備え、レンズカバー１２は、レンズ２とミラー３を備えた設置盤８の表面に対して略平行移動するよう開閉駆動機構１３に接続されている。開閉駆動機構１３は、レンズカバー１２の台部となる所定長さの配置部材１４と、配置部材１４に回転接続軸１５を介して係合し且つ設置盤８の回転支持軸１６により設置盤８の表面で揺動し得るよう形成された第一のアーム部１７と、第一のアーム部１７に連動して揺動するよう設置盤８の裏面で回転支持軸１６に接続され且つ設置盤８の側方外部へ延在して設置盤８の側方外部位置に上方へ突設する凸部１８を備える第二のアーム部１９と、凸部１８に接するよう延在部２０を備えて設置盤８の裏面支持部２１に支持されるスプリング２２とを備えている。ここで、第一のアーム部１７は、回転接続軸１５を一端に配置すると共に回転支持軸１６を他端に配置し、第二のアーム部１９は、回転支持軸１６を一端に配置すると共に凸部１８を他端に配置している。又、第一のアーム部１７と第二のアーム部１９は、回転支持軸１６を介して略直線上に配置されると共に、第一のアーム部１７の長さを第二のアーム部１９の長さよりも長く形成しており、回転支持軸１６を支点とするよう第一のアーム部１７及び第二のアーム部１９を揺動させた際には、凸部１８の移動量に対して回転接続軸１５の移動量を大きくなるよう構成されている。
【００２３】
一方、設置盤８の中途位置には、配置部材１４に当接して、レンズカバー１２を、レンズ２及びミラー３を覆う所定位置に停止させる凸状の上方停止ガイド部２３を備え、設置盤８の下部には、移動したレンズカバー１２を、レンズ２及びミラー３を露出させる位置に停止させる凸状の下方停止ガイド部２４を備え、設置盤８の側部には、レンズカバー１２が移動する際に、配置部材１４の端部が接触してレンズカバー１２の移動姿勢を制御するようレンズカバー１２の移動方向に沿って形成された凸状の制御ガイド部２５を備えている。又、設置盤８を挟み込む外側ケース９には、レンズカバー１２に当接して、レンズカバー１２を、レンズ２及びミラー３を覆う位置に停止させるスポンジ製のケース側停止ガイド部２６を備えている。ここで、スポンジ製のケース側停止ガイド部２６は、カメラ付き携帯端末１の着信時に振動体（いわゆる着信報知用バイブレータ、図示せず）の振動によって発生するレンズカバー１２の振動音（いわゆるビビリ音）を防止するよう構成されており、振動音防止用の停止ガイド部材の材質には、振動防止に効果のある弾性体をスポンジやゴム等から適宜選択して用いることが好ましい。
【００２４】
第二のアーム部１９の凸部１８には、第二のアーム部１９を揺動させる開閉操作部２７を接続しており、開閉操作部２７は、凸部１８を挟み込んで接続する連動部材２８と、連動部材２８より延在して筺体表示部５の側部外面でスライド可能に配置される開閉ノブ２９と、設置盤８に形成された突出部３０に接触して開閉ノブ２９及び連動部材２８の移動を所定方向に規制するよう連動部材２８より延在する制御部材３１とを備えている。
【００２５】
設置盤８の裏面支持部２１に支持されるスプリング２２は、延在部２０を閉止側延在部２０ａと開放側延在部２０ｂに分けるよう屈曲点２０ｃを形成しており、第二のアーム部１９の凸部１８が屈曲点２０ｃを超えた際には、スプリング２２の弾性により凸部１８を所定の移動方向に余勢するよう構成されている。ここで、延在部２０を閉止側延在部２０ａと開放側延在部２０ｂに分ける屈曲点２０ｃの角度は凸部１８に作用するスプリング２２の弾性力を最適にするものである。
【００２６】
以下、本発明のカメラ付き携帯端末を実施する形態例の作用を説明する。
【００２７】
カメラ付き携帯端末１のカメラを使用する場合には、初めに、折り畳まれている筺体表示部５と筺体操作部７を開き、開閉操作部２７の開閉ノブ２９を手動で開放側へスライドさせることにより、連動部材２８、凸部１８を介して、第二のアーム部１９及び第一のアーム部１７を揺動させ、更に第一のアーム部１７の揺動により配置部材１４を介してレンズカバー１２を開閉ノブ２９の反スライド側へ移動させ、レンズ２とミラー３を露出する。同時に、開閉ノブ２９を開放側へ移動させることに連動して、内部のプログラム回路（図示せず）は、電話等の通信を待つ状態の着信待ち受けモードから撮影を可能にするカメラモードに切り換えており、撮影対照物にレンズ２を向けてシャッターボタンとなるセンターキー６ａを押すことにより撮影可能となる。ここで、開閉操作部２７の開閉ノブ２９を手動で開放側にスライドさせた際には、凸部１８がスプリング２２の閉止側延在部２０ａを摺動し、凸部１８の移動位置が屈曲点２０ｃを超えた時点でスプリング２２の弾性力により凸部１８を開放側延在部２０ｂの端側へ摺動させて第二のアーム部１９、第一のアーム部１７及びレンズカバー１２を全開放側へ余勢する。なお、凸部１８の移動位置が屈曲点２０ｃを超えない時点で開閉ノブ２９のスライドを停止した場合には、スプリング２２の弾性力により凸部１８がスプリング２２の閉止側延在部２０ａを逆方向に摺動し、凸部１８を介して第二のアーム部１９、第一のアーム部１７及びレンズカバー１２を全閉止側へ戻す。
【００２８】
カメラ付き携帯端末１のカメラを使用しない場合には、開閉操作部２７の開閉ノブ２９を手動で閉止側へスライドさせることにより、連動部材２８、凸部１８を介して、第二のアーム部１９及び第一のアーム部１７を逆方向へ揺動させ、更に第一のアーム部１７の逆方向の揺動により配置部材１４を介してレンズカバー１２を開閉ノブ２９の反スライド側へ移動させ、開放窓１１を塞ぐと共にレンズ２とミラー３を覆い隠す。同時に、レンズカバー１２を閉止側へ移動させることに連動して、内部のプログラム回路（図示せず）は、撮影を可能にするカメラモードから電話等の通信を待つ状態の着信待ち受けモードに切り換えており、電話等の通信機器を使用し得る状態にする。更に全て終了する場合には筺体表示部５と筺体操作部７を折り畳む。ここで、開閉操作部２７の開閉ノブ２９を手動で閉止側にスライドさせた際には、凸部１８がスプリング２２の開放側延在部２０ｂを摺動し、凸部１８の移動位置が屈曲点２０ｃを超えた時点でスプリング２２の弾性力により凸部１８を閉止側延在部２０ａの端側へ摺動させて第二のアーム部１９、第一のアーム部１７及びレンズカバー１２を全閉止側へ余勢する。なお、凸部１８の移動位置が屈曲点２０ｃを超えない時点で開閉ノブ２９のスライドを停止した場合には、スプリング２２の弾性力により凸部１８がスプリング２２の開放側延在部２０ｂを逆方向に摺動し、凸部１８を介して第二のアーム部１９、第一のアーム部１７及びレンズカバー１２を全開放側へ戻す。
【００２９】
このように、カメラ付き携帯端末１によれば、開閉駆動機構１３によりレンズカバー１２に触れることなくレンズカバー１２を略平行移動させるので、薄型且つレンズカバー１２の大きさを最小限にして全体の美観を向上させることができる。又、レンズカバー１２に触れることなくレンズカバー１２を移動させるので、レンズカバー１２と略同じ位置にあるレンズ２及びミラー３に誤って指が接触することを防止し、レンズ２及びミラー３を汚す虞れを無くすことができる。
【００３０】
第二のアーム部１９に係合される開閉操作部２７を備え、開閉操作部２７の開閉ノブ２９を手動で移動させるよう構成すると、開閉操作部２７を手動でスライドさせることにより第二のアーム部１９及び第一のアーム部１７を介してレンズカバー１２を移動させるので、レンズカバー１２の移動を簡単な構成で為し、結果的に製造コストを低減することができる。
【００３１】
第一のアーム部１７及び第二のアーム部１９を支持する回転支持軸１６を、開閉操作部２７寄りに配置し、凸部１８及び開閉操作部２７の移動量に対して回転接続軸１５及びレンズカバー１２の移動量を大きくするよう構成すると、開閉操作部２７を僅かに移動させることによりレンズカバー１２を大きく移動させるので、開閉操作部２７の移動範囲を小さくして開閉操作部２７の移動に必要な範囲を低減し、全体の美観を一層向上させることができる。又、開閉操作部２７を僅かに移動させてレンズカバー１２を開閉し得るので、レンズ２及びミラー３に誤って指が接触することを防止し、レンズ２及びミラー３を汚す虞れを確実に無くすことができる。
【００３２】
レンズカバー１２を、所定位置に停止させる上方停止ガイド部２３、ケース側停止ガイド部２６、及び下方停止ガイド部２４と、レンズカバー１２の移動を制御する制御ガイド部２５とを備えると、レンズカバー１２の誤った位置への停止を防止すると共にレンズカバー１２の誤った動作を防止するので、レンズカバー１２の開閉を確実に行うことができる。
【００３３】
第二のアーム部１９より突出する凸部１８と、該凸部１８に接するよう延在部２０を形成するスプリング２２とを備え、前記スプリング２２は、延在部２０を閉止側延在部２０ａと開放側延在部２０ｂに分けるよう屈曲点２０ｃを形成し、前記凸部１８が屈曲点２０ｃを超えることにより開閉操作部２７、第二のアーム部１９、第一のアーム部１７が余勢されるよう構成されると、凸部１８が屈曲点２０ｃを超えることによってスプリング２２が開閉操作部２７、第二のアーム部１９及び第一のアーム部１７を全開放側もしくは全閉止側へ余勢するので、開閉操作部２７の移動及びレンズカバー１２の開閉を容易に行うことができる。又、凸部１８がスプリング２２の屈曲点２０ｃを超えた場合には、開閉操作部２７を僅かに移動させることによってスプリング２２の余勢によりレンズカバー１２を開閉し得るので、レンズ２及びミラー３に誤って指が接触することを防止し、レンズ２及びミラー３を汚す虞れを一層確実に無くすことができる。
【００３４】
カメラのレンズ２を覆うレンズカバー１２を移動させてレンズ２を露出させる開閉駆動機構１３が、回転支持軸１６により支持されてレンズカバー１２に係合する第一のアーム部１７と、第二のアーム部１９より突出する凸部１８と、該凸部１８に接するよう延在部２０を形成するスプリング２２と、第二のアーム部１９に係合させる開閉操作部２７とを備え、前記スプリング２２は、延在部２０を閉止側延在部２０ａと開放側延在部２０ｂに分けるよう屈曲点２０ｃを形成し、前記凸部１８が屈曲点２０ｃを超えることにより、開閉操作部２７、第二のアーム部１９及び第一のアーム部１７が余勢されるよう構成されると、凸部１８が屈曲点２０ｃを超えることによってスプリング２２が開閉操作部２７、第二のアーム部１９及び第一のアーム部１７を全開放側もしくは全閉止側へ余勢するので、開閉操作部２７の移動及びレンズカバー１２の開閉を容易に行うことができる。又、凸部１８がスプリング２２の屈曲点２０ｃを超えた場合には、開閉操作部２７を僅かに移動させることによってスプリング２２の余勢によりレンズカバー１２を開閉し得るので、レンズ２及びミラー３に誤って指が接触することを防止し、レンズ２及びミラー３を汚す虞れを一層確実に無くすことができる。
【００３５】
尚、本発明のカメラ付き携帯端末は、上述の図示例にのみ限定されるものではなく、開閉駆動機構を手動で駆動させる代わりに電動で駆動させるようにしてもよいこと、その他、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。
