Description

【０００１】
【発明の属する技術分野】
本発明は、本体部に対して回動自在なスピーカ等の可動部を備える電子機器に関する。
【０００２】
【従来の技術】
本体部に対して回動自在な可動部を備える電子機器として、例えば、開閉式のスピーカを備えるオーディオプレーヤ、折り畳み式の携帯電話、ノート型のパソコン等が知られている。
この種の電子機器では、例えば、軸部と軸受け部とからなるヒンジ部を介して、本体部と可動部とを相互に連結することによって、本体部に対して可動部が回動自在に保持されるようになっている。
また、上記電子機器の中には、例えば、軸部の外周面に凹部を備える一方、軸受け部の内周面に凹部と係合可能な凸部を備え、それら凹部と凸部とが係合した状態にて軸部の回動が規制されるように構成された電子機器もある。このような電子機器によれば、予め定められた所定の回動角度（つまり、凸部と凹部が出会う回動角度）で可動部の姿勢を維持することができる。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記従来の電子機器において、例えば、複数の成形部材を接合して上記軸部を形成する場合には、各部材の成形誤差等によって、各部材の接合部に段差が生じてしまうことがあった。例えば、軸部の外周面に段差が生じた場合には、本体部に対して可動部を回動させるときに、引っかかりが生じて、可動部を滑らかに回動させることができないという問題点があった。特に、軸受け部の内周面に、可動部の姿勢を維持するための凸部或いは凹部を設けた場合には、僅かな段差であっても、その段差部分（係合位置以外の部分）に凸部或いは凹部が引っかかって、可動部の姿勢をスムーズに回動変換することができなかった。
なお、上記段差の原因となる突出部分を削り取るなどして段差をなくすことも可能であるが、それには非常に手間がかかり、結果として電子機器の製造コストが増大してしまうという問題点があった。
【０００４】
本発明は、上記実状に鑑みなされたもので、予め定められた所定の回動角度で可動部の姿勢を維持することができ、しかも可動部の姿勢をスムーズに回動変換することができる電子機器を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、
請求項１記載の発明は、例えば、図１〜図３に示すように、
本体部１と、この本体部１に回動可能に支持された可動部２とを備える電子機器１０であって、
前記可動部２が前記本体部１に対して、前記可動部２と前記本体部１の何れか一方に設けられた軸部３と他方に設けられた軸受け部４との相互作用により回動可能に支持される構成とし、
前記軸部３は被係合部５を備える一方、
前記軸受け部４は、前記本体部１に対する前記可動部２の回動角度が所定の回動角度にあるときに前記被係合部５と係合し、該係合状態にて前記軸部３の回動を規制する係合部６を備え、
前記軸部３は複数の部材を接合してなり、前記被係合部５は前記軸部３の軸線方向に延びる凹部によって構成され、前記軸部３を構成する部材の接合部７の接合面が前記被係合部５を通るように設けられていることを特徴としている。
【０００６】
請求項１記載の発明によれば、軸受け部の係合部と係合可能な被係合部を、軸部を構成する各部材の接合部に設けるようにしたので、被係合部以外の位置に段差が生じ難くなる。従って、被係合部と係合部とが出会って係合する所定の回動角度において、可動部の姿勢を維持することができる一方で、前記所定の回動角度以外の回動範囲において、可動部を滑らかに回動させることができる。つまり、可動部の姿勢をスムーズに回動変換することができる。
なお、この場合には、被係合部以外の位置に段差が生じ難くなる一方で、被係合部の位置に段差が生じ易くなるが、例えば、被係合部の位置に段差が生じたとしても、可動部の回動に何ら支障はなく、段差による影響は少ない。
【０００７】
ここで、電子機器としては、例えば、オーディオプレーヤ、携帯電話、携帯情報端末などの電子機器が挙げられるが、本体部に対して回動自在な可動部を備える電子機器であれば如何なるタイプの電子機器であっても良い。
可動部としては、例えば、スピーカ、ディスプレイ、操作パネルなどが挙げられる。
所定の回動角度には、例えば、電子機器の使用時に可動部が維持される回動角度や、電子機器の不使用時或いは搬送時に可動部が維持される回動角度などが含まれる。
被係合部としては、例えば、軸部の外周面に設けられる凹部（溝条、窪み）や、軸部の外周面に設けられる凸部（突条、突出部）などが挙げられる。
【０００８】
請求項２記載の発明は、請求項１記載の電子機器１０において、
例えば、図３及び図５に示すように、
前記軸部３には、その周方向に沿って複数の被係合部５が設けられていることを特徴としている。
【０００９】
請求項２記載の発明によれば、軸部の周方向に沿って複数の被係合部を設けたので、回動角度の異なる複数種類の回動状態にて可動部の姿勢を維持できるようになる。
【００１０】
請求項３記載の発明は、請求項２記載の電子機器１０において、
例えば、図２に示すように、
前記可動部２は開閉式のスピーカ２によって構成され、
前記複数の被係合部５には、
前記スピーカ２が前記本体部１に対して閉状態の回動角度にあるときに前記係合部６と係合する第１の被係合部５aと、前記スピーカ２が前記本体部１に対して開状態の回動角度にあるときに前記係合部６と係合する第２の被係合部５bと、が含まれることを特徴としている。
【００１１】
請求項３記載の発明によれば、複数の被係合部には、スピーカが本体部に対して閉状態の回動角度にあるときに係合部と係合する第１の被係合部と、スピーカが本体部に対して開状態の回動角度にあるときに係合部と係合する第２の被係合部と、が含まれるので、当該電子機器の使用状態に応じて、スピーカの姿勢を開状態と閉状態の各々の状態に維持できる。従って、電子機器の使い勝手を向上させることができる。
【００１２】
請求項４記載の発明は、請求項１〜３のいずれかに記載の電子機器１０において、
例えば、図４及び図５に示すように、
前記係合部６は、前記軸受け部４の軸線からの距離が周方向に沿って曲線的に変化する凸部によって構成されるとともに、前記被係合部５は、前記係合部６の形状に対応して断面形状が滑らかなカーブ形状に形成される凹部によって構成され、
前記可動部２に対して所要の回動力を付与することによって、前記被係合部５と前記係合部６との係合状態が解除されるようになっていることを特徴としている。
【００１３】
請求項４記載の発明によれば、可動部に対して所要の回動力を付与することによって、被係合部と係合部との係合状態が解除されるようになっているので、軸部に対する回動規制を容易に解除することができる。
【００１４】
請求項５記載の発明は、請求項１〜４のいずれかに記載の電子機器１０において、
例えば、図３に示すように、
前記軸部３には、その軸線方向に線材を通す線材挿通孔８が設けられていることを特徴としている。
【００１５】
請求項５記載の発明によれば、軸部に線材挿通孔を設けたので、軸部の軸線方向に沿って線材を通すことが可能となり、可動部と本体部とに亘って信号線等の線材を配線するのが容易となる。
【００１６】
ここで、線材としては、例えば、信号線、電源コード、アース線、チューブなどが挙げられる。
【００１７】
【発明の実施の形態】
以下、図面を参照して、本発明の実施の形態について説明する。
図１は本発明に係る電子機器１０の一例を示すもので、（ａ）は前方斜視図、（ｂ）は後方斜視図、（ｃ）は側面図である。
【００１８】
この実施の形態の電子機器１０は、開閉式（折り畳み式）のスピーカ２を備えるオーディオプレーヤであって、本体部１と、該本体部１の両側部に回動自在に取り付けられた一対のスピーカ（可動部）２とによって概略構成されている。
各スピーカ２には、図３に示すように、上下両方向に延びる一対の軸部３が設けられる一方、本体部１には、それら軸部３に対応して複数の軸受け部４が設けられ、それら軸部３と軸受け部４との相互作用によって、スピーカ２が本体部１に対して回動自在に支持される構成となっている。また、図１及び図２に示すように、本体部１及び各スピーカ２は何れも薄厚の略直方体形状に形成され、各スピーカ２の回動範囲は、スピーカ２の側壁面が本体部の側壁面に当接してスピーカ２の前面側（放音側）が前方を向くときの回動角度（スピーカ２が開状態にあるときの回動角度）から、スピーカ２の裏面側が本体部１の裏面に当接してスピーカ２の前面側が後方を向くときの回動角度（スピーカが閉状態にあるときの回動角度）までの約１８０度の回動範囲に制限されている。
【００１９】
本体部１は、ＣＤ及びＭＤの再生録音装置、ラジオのチューナー等を備えて構成され、その筐体部１ａの左右両側には、図１及び図３に示すように、上下で対をなす軸受け部材１７が、略円筒状の取付部９にそれぞれ内包される状態で取り付けられている。
各軸受け部材１７は柔軟性を有する樹脂によって形成され、スピーカ２の各軸部３と対応する位置にそれぞれ配置されている。
この軸受け部材１７は、図３及び図４に示すように、軸部３を嵌入する嵌入孔１１を有し該嵌入孔１１内で軸部３を回動自在に保持する軸受け部４と、該軸受け部４の外周面より延出する一対の取付板部１２と、を備えて構成されている。この軸受け部材１７は、取付板部１２が互いに当接して軸受け部４が略円筒状をなす状態（図４の状態）で筐体部１ａに取り付けられている。
軸受け部４の内周面には、軸部３の被係合部５（後述）と係合離脱自在であって該係合状態にて軸部３の回動を規制可能な係合部６が設けられている。この係合部６は、軸線方向に延びる突条（凸部）によって構成され、その断面形状は、軸線からの距離が周方向に沿って曲線的に変化する略半円形状となっている。
【００２０】
スピーカ２は、図３に示すように、スピーカ本体１８と、このスピーカ本体１８の裏面側より後方に向けて延出し先端部が外側方に向けて屈曲するアーム部１９とを備えて構成されている。
スピーカ本体１８の大きさは、図１に示すように、高さが本体部１とほぼ同じで幅が本体部の約半分に設定されている。つまり、両スピーカを閉じたとき（両スピーカを折り畳んだとき）の電子機器１０の横幅がスピーカ２を開いたときの約半分となるように構成されている。このスピーカ本体１８には、その開閉に際して本体部１の側壁面に当接する部位と、本体部の裏面に当接する部位の各々に、衝撃を吸収する緩衝部材１４が取り付けられ、これによって、スピーカ２と本体部１との当接時における衝撃が緩衝されるようになっている。
【００２１】
アーム部１９先端の上面及び下面には、同一直線上に軸線を有する略円柱形状の軸部３がそれぞれ立設されている。
各軸部３の中心部には、その軸線方向に沿って線材挿通孔８が設けられ、この線材挿通孔８には、スピーカ本体１８から本体部１へと延びる信号線１５が配線されている。また、線材挿通孔８には、複数の信号線１５を束ねて係止するための配線係止部１６が設けられている。
一方、軸部３の外周面には、軸受け部４の係合部６と係合離脱自在な一対の被係合部５が約１８０度間隔で設けられている。具体的に、一方の被係合部（第１の被係合部）５aは、スピーカ２が本体部１に対して閉状態の回動角度にあるときに軸受け部４の係合部６と係合する位置に設けられ、他方の被係合部（第２の被係合部）５bは、スピーカ２が本体部１に対して開状態の回動角度にあるときに軸受け部４の係合部６と係合する位置に設けられている。つまり、スピーカ２が回動し得る範囲の限界となる回動角度にあるときに、係合部６と被係合部５とが係合し、これによって、軸部３の回動が規制されて、スピーカ２の姿勢が安定した状態で保たれるようになっている。
各被係合部５は、図３及び図６に示すように、軸線方向に延びる溝条（凹部）によって構成され、その断面形状は、係合部６の形状に対応して滑らかなカーブ形状となっている。つまり、スピーカ２に対して所要の回動力を付与することによって、被係合部５と係合部６との係合状態を容易に解除できるようになっている。また、被係合部５と係合部６とが係合するときには、係合部６である突条が被係合部５である溝条に嵌入することによって、軸受け部４の周方向にかかるテンションが弱められると同時に、所望のクリック感が得られるようになっている。
【００２２】
また、上記軸部３は、図５に示すように、複数の部材を接合することによって構成されている。即ち、図３に示すように、スピーカ本体１８の裏面ほぼ全域及びアーム部１９の内側面を構成する合成樹脂製の第１ケース部材２０ａと、アーム部の外側面を構成する合成樹脂製の第２ケース部材２０ｂとをビス２１で相互に接合することによって、アーム部１９先端の上下両面に軸部３がそれぞれ形成されるようになっている。
さらに、前述した各被係合部５は、図５に示すように、各ケース部材２０ａ、２０ｂの接合部７に設けられている。即ち、各ケース部材２０ａ、２０ｂの接合面が各被係合部５を通るように、各ケース部材２０ａ、２０ｂの形状が予め設定されている。従って、軸部３の外周面には、被係合部５の位置を除いて段差が生じ難くなっている。
【００２３】
次に、スピーカ２の動作について説明する。
【００２４】
常時は、各スピーカ２の前面側が前方に向けられた状態（開状態）となっている。このとき、図６（ａ）に示すように、軸部３の被係合部（第２の被係合部）５ｂと軸受け部４の係合部６とが係合して、軸部３の回動が規制された状態となっている。従って、スピーカ２に多少の外力が加わったとしても、スピーカ２の姿勢をそのままの状態で維持することができる。この状態で、当該電子機器１０が使用される。
この状態から、図２に示すように、スピーカ２を後ろに折り畳む方向に、スピーカ２に対して所要の回動力を付与すると、図６（ｂ）に示すように、係合部６から被係合部５ｂが離脱して、係合部６と被係合部５ｂとの係合が解除された状態となる。この状態では、軸部３に対する回動規制が解除されて、スピーカ２を自由に回動させることができる。特に、この実施の形態の電子機器１０によれば、前述したように、軸部３の外周面に段差が生じ難い構成となっていることから、被係合部５以外の回動範囲では、スピーカ２を滑らかに回動させることができる。つまり、スピーカ２の姿勢をスムーズに回動変換することができる。
そして、そのままスピーカ２を約１８０度回動させると、スピーカ本体１８の裏面が本体部１の裏面に当接すると共に、図６（ｃ）に示すように、軸部３の被係合部（第１の被係合部）５ａが軸受け部４の係合部６と出会って、被係合部５ａと係合部６とが係合状態となる。即ち、図１に示すように、スピーカ２の前面側が後方を向く閉状態（つまり、本体部１の後ろにスピーカ２が折り畳まれた状態）となって、この状態で、軸部３の回動が規制されて、スピーカ２の姿勢が維持される。例えば、この状態で、当該電子機器１０が収納或いは搬送される。
また、この状態から、スピーカ２を開く方向に、スピーカ２に対して所要の回動力を付与すると、前述と同様に、係合部６と被係合部５ａとの係合状態が解除される。そして、そのままスピーカ２を約１８０度回動させれば、被係合部５ｂと係合部６とが出会って係合状態となり、スピーカ２の前面側が前方を向く状態で、スピーカ２の姿勢が維持される。つまり、当該電子機器１０が元の状態（開状態）に戻る。
【００２５】
本実施の形態の電子機器１０によれば以下のような効果が得られる。
軸受け部４の係合部６と係合可能な被係合部５を、軸部３を構成する各部材２０の接合部７に設けるようにしたので、被係合部５以外の位置に段差が生じ難くなる。従って、被係合部５と係合部６とが出会って係合する所定の回動角度において、スピーカ２の姿勢を維持することができる一方で、前記所定の回動角度以外の回動範囲において、スピーカ２を滑らかに回動させることができる。つまり、スピーカ２の姿勢をスムーズに回動変換することができる。
【００２６】
また、軸部３の周方向に沿って複数の被係合部５を設けたので、回動角度の異なる複数種類の回動状態にてスピーカ２の姿勢を維持できるようになる。
【００２７】
また、複数の被係合部５には、スピーカ２が本体部１に対して閉状態の回動角度にあるときに係合部６と係合する第１の被係合部５aと、スピーカ２が本体部１に対して開状態の回動角度にあるときに係合部６と係合する第２の被係合部５bと、が含まれるので、当該電子機器１０の使用状態に応じて、スピーカ２の姿勢を開状態と閉状態の各々の状態で維持できる。従って、電子機器１０の使い勝手を向上させることができる。さらに、スピーカ２の内側側面及び裏面には緩衝材１４が設けられているので、スピーカ２の開閉時に衝撃を吸収させることができる。
【００２８】
また、スピーカ２に対して所要の回動力を付与することによって、被係合部５と係合部６との係合状態が解除されるようになっているので、軸部３に対する回動規制を容易に解除することができる。さらに、軸受け部４は柔軟な樹脂で形成されているのでよりいっそうスムーズに係合状態を解除することができる。従って、スピーカ２の姿勢を容易に回動変換することができる。
【００２９】
また、軸部３の軸線方向に沿って線材挿通孔８を設けたので、スピーカ２と本体部１とに亘って信号線１５を配線するのが容易となる。
【００３０】
また、取付部９によって、信号線１５が覆い隠されるので、当該電子機器１０の見映えをよくすることができる。また取付部９によって信号線１５を保護することもできる。さらに、係合部６である突条が被係合部５である溝条に嵌入することによって、スピーカ２を開状態または閉状態に回動変換したときに使用者は所望のクリック感を得ることができる。なお、この実施の形態の電子機器１０によれば、各ケース部材の成形誤差等によって、被係合部５の位置に多少の段差が生じる可能性があるが、この実施の形態では、係合部６の形状を、軸線からの距離が周方向に沿って曲線的に変化する略半円形状としたので、被係合部５の位置に多少の段差が生じたとしても、被係合部５と係合部６とを係合させて該係合位置で軸部３の回動を規制することができ、また、スピーカ２に対して所要の回動力を付与すれば、被係合部５と係合部６との係合状態を簡単に解除できる。つまり、被係合部５の位置に多少の段差が生じたとしても、予め定められた所定の回動角度でスピーカ２の姿勢を維持することができ、しかもスピーカ２の姿勢をスムーズに回動変換することができる。
【００３１】
なお、本実施の形態では前記電子機器１０を開閉式スピーカ２を備えたオーディオプレーヤとしたが、これに限らず、例えば、その他のオーディオプレーヤや折り畳み式の携帯電話、ノート型のパソコン等としてもよい。また、被係合部５を凹部、係合部６を凸部としたが、被係合部５を凸部、係合部６を凹部としてもよい。
【００３２】
【発明の効果】
以上説明したように、本発明の請求項１の発明によれば、軸受け部の係合部と係合可能な被係合部を、軸部を構成する各部材の接合部に設けるようにしたので、被係合部以外の位置に段差が生じ難くなる。従って、可動部の姿勢をスムーズに回動変換することができる。
【００３３】
請求項２の発明によれば、請求項１と同様の効果を得ることができるのは勿論のこと、軸部の周方向に沿って複数の被係合部を設けたので、回動角度の異なる複数種類の回動状態にて可動部の姿勢を維持できるようになる。
【００３４】
請求項３の発明によれば、請求項２と同様の効果を得ることができるのは勿論のこと、複数の被係合部には、スピーカが本体部に対して閉状態の回動角度にあるときに係合部と係合する第１の被係合部と、スピーカが本体部に対して開状態の回動角度にあるときに係合部と係合する第２の被係合部と、が含まれるので、当該電子機器の使用状態に応じて、スピーカの姿勢を開状態と閉状態の各々の状態で維持できる。
【００３５】
請求項４の発明によれば、請求項１〜３と同様の効果を得ることができるのは勿論のこと、可動部に対して所要の回動力を付与することによって、被係合部と係合部との係合状態が解除されるようになっているので、軸部に対する回動規制を容易に解除することができる。

[0003]
[Problems to be solved by the invention]
However, in the above-described conventional electronic device, for example, when the shaft portion is formed by joining a plurality of molded members, a step may be generated in the joint portion of each member due to a molding error of each member. there were. For example, when a step is generated on the outer peripheral surface of the shaft portion, there is a problem that when the movable portion is rotated with respect to the main body portion, the movable portion cannot be smoothly rotated due to catching. there were. In particular, when a convex portion or a concave portion for maintaining the posture of the movable portion is provided on the inner peripheral surface of the bearing portion, even if there is a slight step, the step portion (portion other than the engagement position) The convex portion or the concave portion is caught, and the posture of the movable portion cannot be smoothly rotated and converted.
Although it is possible to eliminate the level difference by, for example, scraping off the protruding portion that causes the level difference, this is very time consuming, resulting in an increase in the manufacturing cost of the electronic device. It was.
