【発明の属する技術分野】
この発明は、携帯電話機やPHS電話機などの携帯型情報通信機に着脱自在に装着し、画像・映像信号を送受信するためのアダプタに関し、具体的には、撮像部に不用意に外力が加わったとき、この撮像部を保護する構成としたアダプタに係る。
【0002】
【従来の技術】
携帯型情報通信機である携帯電話機やPHS電話機は送受話専用機であるため、画像・映像信号を送受信することができないが、今日では、パソコンやデジタルカメラから画像・映像信号を携帯型電話機に入力し、この電話機により画像・映像信号を送受信する通信システムが開発されている。
【0003】
また、撮像機能と画像・映像信号の処理機能とを備えたアダプタを携帯型電話機に装着し、アダプタと電話機の間で画像・映像信号を直接授受させ、画像・映像信号を電話機によって送信し、また、受信し、携帯型電話機相互間で画像・映像信号を送受信できるようにしたアダプタ付の電話機が開発されている。
このような電話機は、受信した画像・映像を表示し、また、送信する画像・映像をモニタできる表示装置を備えている。
【0004】
【発明が解決しようとする課題】
画像・映像信号を送受信するための上記したアダプタには、撮影レンズや撮像素子などの撮像機構を備えた撮像部がアダプタに突出形成した支持腕に軸支されているものがある。
【0005】
そして、このようなアダプタは、撮像部の軸支部が回動自在となっており、撮像部を回動させることで撮影方向を変えるように構成されている。
【0006】
このようなアダプタは、落下させてしまった時のように撮像部に予期しない外力が加わることにより、撮像部の軸支部が破壊し、撮像部がアダプタから取り外れることがあり、また、このような外力が加わると、撮像部自体を破損したり、撮像部を軸支させたアダプタ突出腕などを破壊してしまうと言う問題がある。
【0007】
本発明は上記した実情にかんがみ、アダプタに不用意に外力が加わった場合でも、撮像部とその軸支部の破損を確実に防止する保護機構を設けたこの種のアダプタを提供することを目的とする。
【0008】
【課題を解決するための手段】
上記した目的を達成するために本発明は、携帯型電話機等の情報通信機に着脱自在に装着し、情報通信機によって送受話信号と共に画像・映像信号を送受信するためのアダプタに関する。
【0009】
そして、このアダプタは、アダプタ本体の一側部に突設形成した中空の支持部と、回転軸方向に対して直交する向きとした撮影レンズを有する撮像部としての回転筒とを設け、さらに、前記回転筒の端面から回転軸方向に突出させた突形部と、前記支持部に形成した孔より当該支持部内に挿入した前記突形部に固着し、前記回転筒と一体的に回転させるようにした板と、前記円形板と前記支持部の内面との間に設け、前記回転筒を前記支持部に圧接保持させるばねとを備え、前記板を押動するばねのばね勢力によって撮像部としての前記回転筒を回転可能に支持させたことを特徴とする携帯型情報通信機のアダプタとなっている。
【0010】
【作用】
撮像部としての回転筒をばね勢力によって保持しているから、アダプタを落下させてしまったとき等、撮像部が強い衝撃力(外力)を受けると、この撮像部が揺動してその衝撃力を緩和し、撮像部の破損やその支軸部などの破壊を防止する。
【0011】
衝撃力を受け揺動した後は撮像部がばね勢力によって正常位置に戻るので、撮像部を回動させ任意の撮影方向に変え撮影し、その画像・映像信号を情報通信機を介して送信することができる。
【0012】
【発明の実施の形態】
次に、本発明の一実施形態について図面に沿って説明する。
図1は携帯型の電話機10と画像・映像信号(以下、単に「映像信号」という)を送受信するためのアダプタ30とを示す斜視図である。
【0013】
電話機10は公知構成のもので、偏平化した箱状の本体部10aと平板状の操作部10bとを折り畳み式に連結してあり、使用しないときは、操作部10bを本体部10aに重ね合せるように折り畳み、使用するときは図示するように操作部10bを展開する。
【0014】
この電話機10は文字や映像の表示機構を備え、その表示部11が本体部10aに設けてある。
また、この本体部10aには、受話スピ−カ12、アンテナ13が、さらには、図面では省略してある着信ランプ、呼出音スピ−カなどを備えている。
【0015】
また、操作部11bには、電話ダイヤルとしてのテンキ−、ファンクションキ−、オンフックスイッチなどの各々のキ−14の他に、マイクロホン15、音量調節・機能選択キ−16、電源スイッチ17が備えてある。
さらに、この操作部10bの一端側には、パソコンやアダプタ等と電気接続して信号授受するためのコネクタ(ピン受け)18が設けてある。
【0016】
一方、アダプタ30は、薄型の長方形となっているアダプタ本体部30aの一側部に撮像部31を備えると共に、アダプタ本体部30aの両側にはその長手方向に沿って形成したガイドレ−ル32a、32bが設けてある。
【0017】
撮像部31は撮影レンズを備えた筒部31aを有する回転筒31bから構成してある。
つまり、回転筒31bにはC−MOS撮像素子が内装してあり、撮影レンズを通って入射した被写体像光がこの撮像素子によって電気変換され、その撮像信号がアダプタ本体部30aの信号処理回路に送られる。
なお、被写体像光を電気変換する撮像素子としては、C−MOS撮像素子の他にCCD撮像素子などを使用してもよい。
【0018】
また、この回転筒31bはアダプタ本体部30aに一体形成した支持部33によって回動自在に支持させてある。
具体的には、回転筒31bをその筒軸を中心にして回動操作することで、筒部31aを旋回させ撮影方向を変える構成となっている。
【0019】
ガイドレ−ル32a、32bは、電話機10が備える操作部10bのサイド部を嵌入させるようにして、アダプタ30を電話機10に装着させるもので、操作部10bが最終位置まで嵌入されると、アダプタ30に設けたコネクタピンが操作部10bのコネクタ18に突入し、アダプタ30が電話機10に電気接続される。
【0020】
なお、アダプタ30には、撮像部31から送られる撮像信号や電話機10が受信した映像信号を処理する信号処理回路が備えてあり、この信号処理回路の信号出入力端としてのコネクタピンが設けてある。
【0021】
また、このアダプタ30には、電話機10の電源に対し別途に設けた電源が備えてある。
本実施形態では2本の乾電池34、35を電源電池として装備しており、これら乾電池34、35を収納させる電池収納部36がアダプタ本体部30aの平面部30bに凹状部として設けてある。
なお、このように設けた電池収納部36は、収納された乾電池34、35の高さが平面部30bの面に対してほぼ同じ高さとなるように形成してある。
【0022】
また、電話機10にアダプタ30を装着して送受信する場合、表示部11の映像を見ながら送話し、また、受話する関係上、電話機10を顔面から所定距離だけ離すように手持ちして送受信する。
そのため、このアダプタ30には、電話機10との間で送受話信号を授受するための回路端子手段としてジャック37が設けてあり、マイク付のイヤホン(或いはヘッドホン)のコ−ドの先端に設けたプラグを上記ジャック37に差し込み電気接続する。
【0023】
図2はアダプタ30を電話機10に装着させた状態を示す。
このようにアダプタ30を取付けることによって、撮像部31により撮影した被写体像が表示部11に映し出され、その映像信号が送話信号と共に電話機10によって送信することができ、また、相手から送られた映像信号と受話信号とを受信し、受信した映像信号に応じて表示部11に映し出される映像を見ながら送受信することができる。
なお、送信する映像が表示部11の一方側過半部分に、受信した映像がその他方側過半部分に各々映し出される。
【0024】
また、このようにアダプタ30を電話機10に装着することによって、電話機10の操作部10bがアダプタ30の平面部30b上に重ね合わさるようになり、その操作部10bが電池収納部36の開放口を閉塞する。
このことから、電池収納部36に収納した乾電池34、35の抜け出しが操作部10bによって防止される。
【0025】
図3はアダプタ30を電話機10より取り外した状態を示す。
アダプタ自体を保管し、また、持ち歩くような場合、コネクタピンが何等かの原因によって折り曲げられたり、破損されるようなことがあるため、ガイドレ−ル32a、32bに嵌入させてコネクタピンを保護する保護カバ−50を備えることが好ましい。
【0026】
この保護カバ−50は電話機10の操作部10bとほぼ同じ大きさの形状となっているが、ただ、嵌入先端側の両サイドに突出腕50a、50bが設けてある。
つまり、保護カバ−50をガイドレ−ル32a、32bに嵌入させて押し進めてアダプタ30に装着することにより、アダプタ30のコネクタピンが上記の突出腕50a、50b間に位置するようになる。
【0027】
また、保護カバ−50をアダプタに装着すると、この保護カバ−50がアダプタ30の平面部30bと重り合うことから、電池収納部36の開放口が保護カバ−50によって閉塞される。
この結果、アダプタ30のみを持ち運ぶような場合であっても、乾電池34、35の抜け出しが保護カバ−50によって防止される。
なお、上記保護カバ−50はアダプタ30に嵌入させることにより、その突起50cがアダプタ30の一部に係止して着脱自在に抜け止めされる。
【0028】
図4〜図7はアダプタ30に設けた撮像部31の支軸構成を示し、図4は撮像部31を切欠いて示したアダプタ30の部分的な拡大正面図、図5は撮像部31を切欠いて示したアダプタ30の部分的な拡大側面図、図6は図4上のA−A線拡大断面図、図7は図6上のB−B線に沿って部分的に切断して示した撮像部31の側面図である。
【0029】
これらの図面により分かるように撮像部31は、撮影レンズを備えた筒部31aが回転筒31bに一体形成してあり、この筒部31aが回転筒31bの回動操作にしたがって旋回し撮影方向を変えるようになっている。
また、回転筒31bには既に述べたようにC−MOS撮像素子や撮像回路などからなる撮像機構が備えてある。
【0030】
一方、上記した回転筒31bの円形端面には図8(a)、(b)に拡大して示したところの3つの突形部61が円周方向三等分位置に設けてあり、これら突形部61を支持部33内に突入させて円形板64の外面からねじ込む小ねじによってねじ止めしてある。
なお、上記した突形部61の各々はねじ止め部62と位置決めピン63とより形成してある。
【0031】
また、回転筒31bの円形端面に設けた略半円状の溝65は撮像部31の回動範囲を決めるもので、この溝65には図8(a)に示した如く支持部33に設けた突部38を突入させ回転筒31bが回転できる範囲を決めるようになっている。
さらに、回転筒31bの円形端面中央に設けた円形孔66は、回転筒31b内の撮像回路とアダプタ本体部30aの信号処理回路とを接続させる接続コ−ドの引き出し口である。
【0032】
他方、支持部33はカバ−部39を嵌着させた中空支持部として形成してあり、その円形孔40より上記した回転筒31bの突形部61を支持部33内に突入させてある。
また、支持部33内には上記した円形板64の他に波状ばね67が設けてある。
【0033】
円形板64は図9(a)、(b)に拡大して示した通り、円周方向の三等分位置に小ねじをねじ込むための3つの小孔68とこれら各々の小孔68に付随させた3つの位置決め小孔69とが形成してある。
また、この円形板64には、各々の小孔68間に設けた弧状フランジ70と、中央に形成した円形孔71とが設けてある。
なお、この円形孔71は上記した接続コ−ドの引き出し口となっている。
【0034】
上記した波状ばね67は図10(a)、(b)に拡大して示したように、小幅のリングに形成したばね板であり、板面を波状に起伏形成させた波状ばねとなっている。
【0035】
上記のように形成した円形板64と波状ばね67はカバ−部39を嵌着させる前に支持部33内に組み付ける。
つまり、円形板64のフランジ70の外側に波状ばね67を嵌め合わせた状態で、この円形板64の位置決め小孔69に回転筒31bの位置決めピン63を嵌入させて位置決めする。
【0036】
その後、小ねじ72を円形板64の各小孔68に差し込れ、これら小ねじ72を回転筒31bの各々のねじ止め部62にねじ込み、円形板64と回転筒31bとを一体的に連結する。
このようにして円形板64と波状ばね67とを組み付けた後にカバ−部39を嵌着させる。
【0037】
上記の如く組み付けた円形板64はそのフランジ70と支持部33の内壁との間に所定の間隔が生じ、また、波状ばね67が円形板64と支持部33の内壁との間に配設される。
この結果、波状ばね67のばね勢力によって回転筒31bの円形端面が支持部33に適度の圧接力で接触するため、回転筒31bの支軸部に機械ガタがなく、また、回転筒31bに適度の圧接力をもたせて回動操作することができるから、回転筒31bを任意の回動位置でストップさせる位置決め機構を設ける必要がない。
なお、回転筒31bを回動させた場合、その突形部61が支持部33の円形孔40の孔縁に接しながら旋回する。
【0038】
また、アダプタ30を落下させてしまったり、或いは、撮像部31を他物に衝突させたりして撮像部31に予期しない外力が加わったときには、回転筒31bが波状ばね67のばね勢力に抗して揺動する。
具体的には、回転筒31bが外力によって支持部を支点に傾けば、円形板64の一部がばね勢力に抗して波状ばね67を押動するため、外力が波状ばね67によって緩和されることから、外力によって撮像部31が破損したり、支持部33などを破壊することがない。
また、外力が取り除かれれば、回転筒31bが波状ばね67のばね勢力によって直ちに図示する正常位置に復動する。
【0040】
【発明の効果】
上記した通り、アダプタを落下させてしまったり、或いは、アダプタを他物に衝突させたりすること等によって予期しない外力が撮像部に加わっても、この撮像部がばね勢力に抗して揺動してその外力を緩和する。
この結果、本発明のアダプタによれば、予期できない不用意な衝撃力によって撮像部を破損したり、また、軸支部が破壊して撮像部が取り外れる等の弊害を極力防止することができる。
また、本発明のアダプタは、回転筒がばね勢力によって支持保持されるので、撮像部の支軸部に機械ガタがなく、さらには、回転筒に適度の圧接力をもたせて回転操作することができるから、特に、位置決め機構を設けることなく、撮像部を任意の回動位置に定め撮影方向を決めることができる。

As shown in FIGS. 9 (a) and 9 (b), the circular plate 64 has three small holes 68 for screwing small screws into three equal positions in the circumferential direction, and the small holes 68 are attached to the small holes 68. The three small positioning holes 69 are formed.
The circular plate 64 has an arc-shaped flange 70 provided between the small holes 68 and a circular hole 71 formed at the center.
The circular hole 71 serves as an outlet for the connection code.
[0034]
As shown in FIGS. 10A and 10B in an enlarged manner, the above-mentioned wavy spring 67 is a spring plate formed in a small-width ring, and is a wavy spring in which the plate surface is undulated. .
[0035]
The circular plate 64 and the wavy spring 67 formed as described above are assembled in the support portion 33 before the cover portion 39 is fitted.
That is, with the wavy spring 67 fitted on the outside of the flange 70 of the circular plate 64, the positioning pin 63 of the rotary cylinder 31 b is fitted into the small positioning hole 69 of the circular plate 64 for positioning.
[0036]
Thereafter, the small screws 72 are inserted into the small holes 68 of the circular plate 64, and these small screws 72 are screwed into the respective screwed portions 62 of the rotary cylinder 31b, thereby integrally connecting the circular plate 64 and the rotary cylinder 31b. I do.
After the circular plate 64 and the corrugated spring 67 are assembled in this way, the cover 39 is fitted.
[0037]
The circular plate 64 assembled as described above has a predetermined space between the flange 70 and the inner wall of the support portion 33, and a wave spring 67 is disposed between the circular plate 64 and the inner wall of the support portion 33. You.
As a result, the circular end surface of the rotary cylinder 31b comes into contact with the support portion 33 with an appropriate pressing force by the spring force of the wave spring 67, so that there is no mechanical play on the support shaft of the rotary cylinder 31b, and the rotary cylinder 31b has an appropriate Therefore, there is no need to provide a positioning mechanism for stopping the rotary cylinder 31b at an arbitrary rotation position.
When the rotary cylinder 31b is rotated, the protruding portion 61 rotates while being in contact with the edge of the circular hole 40 of the support portion 33.
[0038]
Further, when an unexpected external force is applied to the imaging unit 31 by dropping the adapter 30 or colliding the imaging unit 31 with another object, the rotating cylinder 31 b resists the spring force of the wave spring 67. Rocks.
Specifically, when the rotating cylinder 31b is tilted about the support portion by the external force with the support portion as a fulcrum, a part of the circular plate 64 pushes the wave spring 67 against the spring force, so that the external force is reduced by the wave spring 67. Therefore, the imaging unit 31 is not damaged by an external force, and the support unit 33 and the like are not broken.
When the external force is removed, the rotary cylinder 31b immediately returns to the illustrated normal position by the spring force of the wave spring 67.
[0040]
【The invention's effect】
As described above, even when an unexpected external force is applied to the imaging unit by dropping the adapter or colliding the adapter with another object, the imaging unit swings against the spring force. To reduce the external force.
As a result, according to the adapter of the present invention, it is possible to prevent the imaging unit from being damaged due to an unexpected and unexpected impact force, or to prevent the imaging unit from being detached due to the breakage of the shaft support as much as possible.
Further, in the adapter of the present invention, since the rotating cylinder is supported and held by the spring force, there is no mechanical backlash in the support shaft of the imaging unit, and furthermore, the rotating cylinder can be rotated with an appropriate pressing force. Therefore, the imaging direction can be determined by setting the imaging unit at an arbitrary rotation position without providing a positioning mechanism.
