従来、主に操作部を有する第１筐体と、主に液晶画面等の表示部を有する第２筐体とが、ヒンジ機構を介して開閉可能な折りたたみ式の携帯端末が知られている。一般的なヒンジ機構は、第１筐体と、第２筐体と、前記第１筐体と前記第２筐体とを回動自在に連結する連結筐体と、前記連結筐体と前記第１筐体とを該第１筐体の短手方向を軸心とする第１軸を中心に回動自在に取り付ける第１ヒンジ部と、前記連結筐体と前記第２筐体とを該第２筐体の長手方向を軸心とする第２軸を中心に回動自在に取り付ける第２ヒンジと、を備え、前記第２ヒンジ部は、前記連結筐体の長手方向に沿って該連結筐体内部に固定された板状の第１連結体と、前記第２筐体の短手方向に沿って該第２筐体内部に固定された板状の第２連結体と、前記第１連結体と前記第２連結体とを、前記第２軸を中心に回動自在に枢着する枢着部と、を有し、前記連結筐体は前記第１ヒンジ部と前記第２ヒンジ部とを連結するとともに、前記第１連結体を覆うように構成したものがある（例えば特許文献１参照）。   2. Description of the Related Art Conventionally, a foldable mobile terminal is known in which a first casing mainly having an operation unit and a second casing mainly having a display unit such as a liquid crystal screen can be opened and closed via a hinge mechanism. A general hinge mechanism includes a first casing, a second casing, a connecting casing that rotatably connects the first casing and the second casing, the connecting casing, and the first casing. A first hinge portion, which is attached to one housing so as to be rotatable about a first axis centered on a short direction of the first housing; and the connection housing and the second housing; A second hinge that pivots about a second axis centered on the longitudinal direction of the casing, and the second hinge portion extends along the longitudinal direction of the coupling casing. A plate-like first connecting body fixed inside the body, a plate-like second connecting body fixed inside the second housing along the short direction of the second housing, and the first connection A body and the second coupling body, and a pivotally pivoting portion pivotably about the second axis, wherein the coupling housing includes the first hinge section and the second hinge section. Together with There is configured to cover the first connecting member (for example, see Patent Document 1).

近年、このような携帯端末の表示部および操作部を用いて、メールの送受信や、ゲームを行ったり、ＴＶ放送を受信したりすることが行われるようになってきた。このような携帯電子機器の使用態様の多様化に伴い、例えば、通話やメールの送受信やゲームを行う場合には、使用者が長方形の表示部を縦長使いで見ながら片手で操作できるように、下筐体（第１筐体）と上筐体（第２筐体）とを連結部（ヒンジ機構）を介して長手方向へ開いて表示部と操作部とを縦長にするいわゆる縦開き状態とするのが便利である。一方、ゲーム、ブラウザやＴＶ受信の場合には、表示部を横長使いで使用するように、第１筐体と第２筐体とを幅方向（短手方向）へ開くいわゆる横開き状態とするのが便利である。   In recent years, using such a display unit and an operation unit of a portable terminal, sending / receiving mails, playing games, and receiving TV broadcasts have been performed. With the diversification of usage modes of such portable electronic devices, for example, when making calls and sending / receiving emails and playing games, so that the user can operate with one hand while viewing the rectangular display part in portrait orientation, A so-called longitudinally open state in which the lower housing (first housing) and the upper housing (second housing) are opened in the longitudinal direction via the connecting portion (hinge mechanism) to make the display unit and the operation unit vertically long. It is convenient to do. On the other hand, in the case of a game, browser, or TV reception, the first casing and the second casing are opened in the width direction (short direction) so that the display unit is used in landscape orientation. Is convenient.

このため、特許文献１に記載の携帯端末においては、連結部（ヒンジ機構）を介して、第１筐体と第２筐体とを縦方向に開く縦開き状態および横方向に開く横開き状態が可能となっている。   For this reason, in the portable terminal described in Patent Document 1, a vertically open state in which the first housing and the second housing are opened in the vertical direction and a laterally open state in which the first housing is opened in the horizontal direction via the connecting portion (hinge mechanism). Is possible.

また、２つの筐体があって、何れか一方の筐体に対して他方の筐体を開閉及び回転可能に連結するヒンジは、開閉軸支持部に回動可能に支持された開閉軸と、該開閉軸を直交状態で回動可能に貫通した回転軸と、前記開閉軸支持部と開閉軸に相互に当接するように設けられた角度規制片と、前記回転軸に突設された規制フランジと前記開閉軸支持部に取り付けられ前記規制フランジに臨む回転規制部と、前記開閉軸の先端にかしめて固着され該開閉軸の抜け止めをする取付板と、を備えたものがある（例えば、特許文献２参照）。
また、開閉可能な第１筐体と第２筐体とは、電線によって電気的に接続され、電線はヒンジ機構に設けた貫通穴を通過させるものが知られている（例えば特許文献３参照）。貫通穴から飛び出した電線は、曲げられて配置される場合がある。 In addition, there are two housings, and a hinge that connects the other housing to one of the housings so as to be able to open and close and rotate, an opening and closing shaft that is rotatably supported by the opening and closing shaft support portion, A rotary shaft that penetrates the open / close shaft in an orthogonal state so as to be rotatable, an angle restricting piece that is provided so as to contact the open / close shaft support portion and the open / close shaft, and a restriction flange that protrudes from the rotary shaft And a rotation restricting portion that is attached to the opening / closing shaft support portion and faces the restriction flange, and a mounting plate that is caulked and fixed to the tip of the opening / closing shaft to prevent the opening / closing shaft from coming off (for example, Patent Document 2).
Moreover, the 1st housing | casing and 2nd housing | casing which can be opened and closed are electrically connected by the electric wire, and the electric wire passes through the through-hole provided in the hinge mechanism (for example, refer patent document 3). . There is a case where the electric wire jumping out of the through hole is bent and arranged.

ところで、近年では、開閉式携帯端末の小型化に伴って連結部にも小型化が求められている。このような要望に対して、貫通穴を小径化したり、さらには枢着部や連結体を小型化することが考えられる。   By the way, in recent years, with the downsizing of the openable portable terminal, the connecting part is also required to be downsized. In response to such a demand, it is conceivable to reduce the diameter of the through hole, and further reduce the size of the pivoting portion and the coupling body.

しかしながら、従来構造の連結部においては、連結体が傾くような外力が加わって、一方の連結体に対して他方の連結体の支持力が弱くなると、ガタが生じやすいという問題が生じる。そのため、一方の連結体と他方の連結体との距離を大きくすることで、生じるガタをできるだけ小さくすることができるが、反面、連結部は小型化できないという問題があった。   However, in the connecting portion having the conventional structure, when an external force that tilts the connecting body is applied and the supporting force of the other connecting body becomes weak with respect to one connecting body, there is a problem that looseness is likely to occur. Therefore, by increasing the distance between one connecting body and the other connecting body, the generated play can be reduced as much as possible, but there is a problem that the connecting portion cannot be reduced in size.

また、従来構造の連結部に使用するヒンジにおいては、開閉軸と回転軸とが一体化されている。それぞれの軸の強度を確保するために所定に軸径とした場合、回転規制部を配置するための配置スペースも開閉軸に沿って確保しなればないので、ヒンジ機構やこれを配置するスペースを十分大きく確保しなければならなかった。そこで、一体化せずとも回転軸の回転規制方法が開示されていれば、適宜選択することができる。そのため、回転規制を備えた小型な回動装置の提案が望まれていた。   Moreover, in the hinge used for the connection part of a conventional structure, the opening and closing shaft and the rotating shaft are integrated. When the shaft diameter is set to a predetermined value to ensure the strength of each shaft, it is necessary to secure a space for placing the rotation restricting portion along the opening / closing shaft. I had to secure it big enough. Therefore, if a method for restricting rotation of the rotating shaft is disclosed without being integrated, it can be selected as appropriate. Therefore, the proposal of the small rotation apparatus provided with rotation control was desired.

また、ヒンジ機構の貫通穴に電線が配置される場合、特許文献２の図６に図示されたように、貫通穴から飛び出した電線は大きな曲率が形成されるように曲げられる。そのため、ヒンジ機構を収容する連結部は、この電線も収容しなければならないため、電線が曲げられて配置される空間を確保しなければならない。このとき、この空間が大きいと連結部が大きくなってしまう。   Moreover, when an electric wire is arrange | positioned at the through-hole of a hinge mechanism, as FIG. 6 of patent document 2 showed in figure, the electric wire jumped out of the through-hole is bent so that a big curvature may be formed. Therefore, since the connection part that accommodates the hinge mechanism must also accommodate this electric wire, a space in which the electric wire is bent must be secured. At this time, if this space is large, the connecting portion becomes large.

本発明は、上記事情に鑑みてなされたもので、前述した課題を解決するためになされたものであり、小型化できる回動装置、及びこれを備えた開閉式携帯端末を提供することを目的とする。   The present invention has been made in view of the above circumstances, and has been made in order to solve the above-described problems.

Alternatively, transmission / reception can be performed in a plurality of bands. The antenna 17 may receive a digital television broadcast or a radio broadcast, or may be used as a transmission / reception antenna for short-range wireless communication.

第２プリント基板１８は、操作部１４の下側であって、第２カメラ部１５の周辺に設けられ、一部にはＵＩＭカード装着部１９や電池２０に接続されるコネクタ（図示せず）を備える。   The second printed circuit board 18 is provided on the lower side of the operation unit 14 and around the second camera unit 15, and a connector (not shown) connected to the UIM card mounting unit 19 and the battery 20 in part. Is provided.

制御部２６は、操作部１４、第１ホール素子１０、第２ホール素子１１、無線回路部２１、データ変換部２２、画像処理部２４及び情報記録部２５接続されており、これらの制御を行う。さらに、制御部２６は、ＵＩＭカード装着部１９や電池２０にも接続されている。   The control unit 26 is connected to the operation unit 14, the first Hall element 10, the second Hall element 11, the wireless circuit unit 21, the data conversion unit 22, the image processing unit 24, and the information recording unit 25, and performs these controls. . Further, the control unit 26 is also connected to the UIM card mounting unit 19 and the battery 20.

無線回路部２１はアンテナ１７に接続されており、アンテナ１７で受信したデータを処理してデータ変換部２２に出力するように構成されている。データ変換部２２は音声処理部２３に接続されており、音声処理部２３は、レシーバ５、スピーカ６及びマイクロフォン１３にそれぞれ接続されている。   The radio circuit unit 21 is connected to the antenna 17 and is configured to process data received by the antenna 17 and output the data to the data conversion unit 22. The data conversion unit 22 is connected to an audio processing unit 23, and the audio processing unit 23 is connected to the receiver 5, the speaker 6, and the microphone 13.

従って、データ変換部２２では、無線回路部２１及び制御部２６を介して、アンテナ１７からの受信データを音声データに変換して音声処理部２３に出力する。   Therefore, the data conversion unit 22 converts the reception data from the antenna 17 into audio data via the wireless circuit unit 21 and the control unit 26 and outputs the audio data to the audio processing unit 23.

音声処理部２３は、音声データを復号化して音声信号を生成した後、レシーバ５やスピーカ６に出力する。レシーバ５やスピーカ６は、音声処理部２３から伝達された音声信号に対応する音声を出力する。   The audio processing unit 23 decodes the audio data to generate an audio signal, and then outputs the audio signal to the receiver 5 and the speaker 6. The receiver 5 and the speaker 6 output sound corresponding to the sound signal transmitted from the sound processing unit 23.

また、音声処理部２３は、マイクロフォン１３が受けた音声を符号化して音声データを生成した後、データ変換部２２に出力する。データ変換部２２は、入力した音声データを通信データに変換した後、無線回路部２１に出力する。無線回路部２１は、受け取った通信データを処理し、アンテナ１７から無線信号の電波として送信する。   The voice processing unit 23 encodes the voice received by the microphone 13 to generate voice data, and then outputs the voice data to the data conversion unit 22. The data conversion unit 22 converts the input voice data into communication data, and then outputs the communication data to the radio circuit unit 21. The radio circuit unit 21 processes the received communication data and transmits it as radio waves from the antenna 17.

第１ホール素子１０と第２ホール素子１１について説明する。第１ホール素子１０は、本体部１が閉状態では第１磁石１６が近接状態にあるため、第１磁石１６の磁界を検出して制御部２６に検出信号を出力する。また、第１ホール素子１０は、本体部１が第１開状態及び第２開状態であれば第１磁石１６が離間するので、第１磁石１６の磁界を検出できないため、第１ホール素子１０は検出信号を生成しない。   The first Hall element 10 and the second Hall element 11 will be described. The first Hall element 10 detects the magnetic field of the first magnet 16 and outputs a detection signal to the control unit 26 because the first magnet 16 is in the proximity state when the main body 1 is closed. Further, since the first magnet 16 is separated when the main body 1 is in the first open state and the second open state, the first hall element 10 cannot detect the magnetic field of the first magnet 16. Does not generate a detection signal.

第２ホール素子１１は、本体部１が閉状態及び第１開状態では、第２磁石３４が近接状態にあるため、第２磁石３４の磁界を検出して制御部２６に検出信号を出力する。また、第２ホール素子１１は、本体部１が第２開状態であれば第２磁石３４が離遠するので、第２磁石３４の磁界を検出できないため、第２ホール素子１１は検出信号を生成しない。   The second Hall element 11 detects the magnetic field of the second magnet 34 and outputs a detection signal to the control unit 26 because the second magnet 34 is in the close state when the main body 1 is in the closed state and the first open state. . In addition, since the second Hall element 11 cannot detect the magnetic field of the second magnet 34 because the second magnet 34 is separated if the main body 1 is in the second open state, the second Hall element 11 outputs a detection signal. Do not generate.

すなわち、第１ホール素子１０が第１磁石１６を検出し、第２ホール素子１１が第２磁石３４を検出すると、本体部１は第１閉状態である。第１ホール素子１０が第１磁石１６を検出せず、第２ホール素子１１が第２磁石３４を検出すると、本体部１は第１開状態である。第１ホール素子１０が第１磁石１６を検出せず、第２ホール素子１１も第２磁石３４を検出しなければ、本体部１は第２開状態である。   That is, when the first Hall element 10 detects the first magnet 16 and the second Hall element 11 detects the second magnet 34, the main body 1 is in the first closed state. When the first Hall element 10 does not detect the first magnet 16 and the second Hall element 11 detects the second magnet 34, the main body 1 is in the first open state. If the first Hall element 10 does not detect the first magnet 16 and the second Hall element 11 does not detect the second magnet 34, the main body 1 is in the second open state.

本体部１を閉状態から第１開状態または第２開状態にすると、操作部１４と第１表示部７が露出し、操作部１４を照明する光源や第１表示部７を照明する光源がオンとなる。所定時間操作されなければ、光源はオフとなる。本体部１が開かれた状態から閉状態にすると、操作部１４や第１表示部７を照明する光源がともにオフとなり、消費電力を低減させる。また、本体部１が閉状態のときに着信すると、第２表示部８に相手先情報が表示される。使用者が着信動作をするために本体部１を第１開状態にすると、第２表示部８に表示された情報は非表示となり、代わりに第１表示部７に表示されるなど、本体部１の態様により、種々、表示の仕方が制御される。   When the main body 1 is changed from the closed state to the first open state or the second open state, the operation unit 14 and the first display unit 7 are exposed, and a light source that illuminates the operation unit 14 and a light source that illuminates the first display unit 7 are provided. Turn on. If not operated for a predetermined time, the light source is turned off. When the main body 1 is changed from the opened state to the closed state, the light sources that illuminate the operation unit 14 and the first display unit 7 are both turned off, thereby reducing power consumption. In addition, when the incoming call is received when the main body 1 is in the closed state, the destination information is displayed on the second display unit 8. When the user places the main body 1 in the first open state for performing an incoming call operation, the information displayed on the second display section 8 is not displayed, but is displayed on the first display section 7 instead. According to the first aspect, various display methods are controlled.

ケーブル３２は、第１プリント基板１２と第２プリント基板１８とを電気的に接続するものである。制御部２６による制御によって、レシーバ５やスピーカ６から音声を出力させる信号、第１カメラ部９や第２カメラ部１５による撮影画像を第１表示部７に表示させるための信号等の送受信が行われる。管部材３３は、両端がテープ３５（図２に片端側のみ図示）によってケーブル３２に固定される。管部材３３は伸縮するため、本体部１への組み付け時、ケーブル３２に対して管部材３３が任意に動くことを防止するために固定される。   The cable 32 is for electrically connecting the first printed circuit board 12 and the second printed circuit board 18. Under the control of the control unit 26, a signal for outputting sound from the receiver 5 and the speaker 6 and a signal for displaying a photographed image by the first camera unit 9 and the second camera unit 15 on the first display unit 7 are transmitted and received. Is called. Both ends of the tube member 33 are fixed to the cable 32 by tapes 35 (only one end side is shown in FIG. 2). Since the tube member 33 expands and contracts, it is fixed to prevent the tube member 33 from moving arbitrarily with respect to the cable 32 when assembled to the main body 1.

次に、連結部４について、図２、図４、図５を用いて詳述する。まず、図４について説明する。連結部４に収容される第２ヒンジ２９は、回動軸部材４１と、保持部材４２と、カム部材４３と、第１ばね部材４４と、筒部材４５と、平坦部材４６と、止め輪４７と、移動部材４８と、第２ばね部材４９と、からなる。この第２ヒンジ２９と隣接して下筐体３に回動不能に取り付けられる取付部材（軸受部材または移動制御部）５０が配置される。   Next, the connection part 4 is explained in full detail using FIG.2, FIG.4, FIG.5. First, FIG. 4 will be described. The second hinge 29 accommodated in the connecting portion 4 includes a rotation shaft member 41, a holding member 42, a cam member 43, a first spring member 44, a tubular member 45, a flat member 46, and a retaining ring 47. And a moving member 48 and a second spring member 49. An attachment member (bearing member or movement control unit) 50 that is non-rotatably attached to the lower housing 3 is disposed adjacent to the second hinge 29.

回動軸部材４１は、細径部５１と、細径部５１に形成された溝部５２と、細径部５１より直径が大きい太径部５３と、太径部５３と直交するように形成されたアーム部５４と、アーム部５４に形成されている第１ねじ穴部５７、第２ねじ穴部５８と、細径部５１と太径部５３に貫通した第１貫通穴５９と、を有する。   The rotating shaft member 41 is formed so as to be orthogonal to the small diameter portion 51, the groove portion 52 formed in the small diameter portion 51, the large diameter portion 53 having a larger diameter than the small diameter portion 51, and the large diameter portion 53. Arm portion 54, first screw hole portion 57 and second screw hole portion 58 formed in arm portion 54, and first through hole 59 penetrating through small diameter portion 51 and large diameter portion 53. .

太径部５３は切欠き面６０を有する。図６に、切欠き面６０を示す。第１ねじ穴部５７、第２ねじ穴部５８は、図６に示すねじ５５、５６によって、上筐体２に固定される。太径部５３は、細径部５１とアーム部５４の間に形成されている。   The large-diameter portion 53 has a notch surface 60. FIG. 6 shows the notch surface 60. The first screw hole portion 57 and the second screw hole portion 58 are fixed to the upper housing 2 by screws 55 and 56 shown in FIG. The large diameter portion 53 is formed between the small diameter portion 51 and the arm portion 54.

保持部材４２は、回動軸部材４１の細径部５１を回動可能に保持、支承する第２貫通穴６１、第３貫通穴６２と、移動部材４８を収容して保持する収容部６３と、第３ねじ部６４と、第１突起部６５と、第２突起部６６と、を有する。第２貫通穴６１に通された細径部５１には、細径部５１と共回りするように取り付けられるカム部材４３と、第１ばね部材４４と、筒部材４５と、平坦部材４６と、が取り付けられる。その後、太径部５３は保持部材４２と当接して、細径部５１先端が保持部材４２の第３貫通穴６２を貫通しないよう、保持部材４２に対して回動軸部材４１が位置決めされる。   The holding member 42 includes a second through hole 61 and a third through hole 62 that rotatably hold and support the small-diameter portion 51 of the rotating shaft member 41, and an accommodating portion 63 that accommodates and holds the moving member 48. The third screw portion 64, the first protrusion portion 65, and the second protrusion portion 66. A cam member 43, a first spring member 44, a tubular member 45, a flat member 46, and a cam member 43 that are attached so as to rotate together with the narrow diameter portion 51. Is attached. Thereafter, the large-diameter portion 53 contacts the holding member 42, and the rotation shaft member 41 is positioned with respect to the holding member 42 so that the tip of the small-diameter portion 51 does not penetrate the third through hole 62 of the holding member 42. .

溝部５２に止め輪４７が取り付けられて、回動軸部材４１が保持部材４２に回動可能に取り付けられる。そして、回動軸部材４１は、保持部材４２からが抜けないように保持される。   A retaining ring 47 is attached to the groove 52, and the rotation shaft member 41 is rotatably attached to the holding member. Then, the rotation shaft member 41 is held so as not to come off the holding member 42.

第１ばね部材４４は、皿ばねが直列配置になるように複数枚重ねられて構成されている。   The first spring member 44 is configured by overlapping a plurality of disc springs so that they are arranged in series.

筒部材４５は、第１ばね部材４４を囲むように設けられる。筒部材４５が第１ばね部材４４を囲むことにより、組み立て中に第１ばね部材４４の中に塵埃の侵入を防止する。また、保持部材４２に対して回動軸部材４１が抜けるような力が作用して、複数枚の皿ばねからなる第１ばね部材４４が全て平坦になるような極度な変形が生じるのを防止する（第１ばね部材４４が永久変形しないようにする）。   The cylindrical member 45 is provided so as to surround the first spring member 44. The cylindrical member 45 surrounds the first spring member 44, thereby preventing dust from entering the first spring member 44 during assembly. Further, it is possible to prevent an extreme deformation that causes the first spring member 44 made up of a plurality of disc springs to be flattened by a force that causes the rotating shaft member 41 to be pulled out with respect to the holding member 42. (The first spring member 44 is prevented from being permanently deformed).

カム部材４３は、回動軸部材４１が回動したときにクリックを発生させる部材である。そのために、細径部５１のスラスト方向に可動可能に設けられる。一側面には凹凸上の第１凹凸面６７が形成され、第１凹凸面６７の反対側は第１ばね部材４４によって付勢される。第１凹凸面６７と対向する保持部材４２にも凹凸状の第２凹凸面６８が形成されている。第１凹凸面６７の凸面と第２凹凸面６８の凹面が対面している状態から、回動軸部材４１とともにカム部材４３が回動すると、第１凹凸面６７の凸面が第２凹凸面６８の凹面が対面している状態から脱出して、第１凹凸面６７の凸面と第２凹凸面６８の凸面が対面する。脱出時に第１ばね部材４４の撓みが増大し、クリックが発生する。また、第１凹凸面６７の凸面と第２凹凸面６８の凸面が対面した状態から、第１凹凸面６７の凸面が第２凹凸面６８の凹面が対面するときには、第１ばね部材４４の撓みが減少して、クリックを発生する。   The cam member 43 is a member that generates a click when the rotation shaft member 41 rotates. Therefore, it is provided so as to be movable in the thrust direction of the small diameter portion 51. A first uneven surface 67 is formed on one side surface, and the opposite side of the first uneven surface 67 is biased by the first spring member 44. The holding member 42 facing the first uneven surface 67 is also formed with an uneven second uneven surface 68. When the cam member 43 rotates together with the rotation shaft member 41 from the state in which the convex surface of the first irregular surface 67 and the concave surface of the second irregular surface 68 face each other, the convex surface of the first irregular surface 67 becomes the second irregular surface 68. The convex surface of the first concave / convex surface 67 and the convex surface of the second concave / convex surface 68 face each other. When the first spring member 44 escapes, the bending of the first spring member 44 increases, and a click occurs. Further, when the convex surface of the first uneven surface 67 and the convex surface of the second uneven surface 68 face each other, when the convex surface of the first uneven surface 67 faces the concave surface of the second uneven surface 68, the first spring member 44 is bent. Decreases and generates a click.

すなわち、回動軸部材４１を回動させるとき、回動に要するトルクが急激に変わるときにクリック感として得られる。クリックが発生する位置は、閉状態から第２開状態へと移行開始するときと、第２開状態への移行を完了するときに発生するように構成されている。使用者は、閉状態から第２開状態へと移行させるとき、移行開始時と移行完了時にクリック感として得られる。また、第２開状態から閉状態へと移行させるときの移行開始時と移行完了時にも、クリック感として得られる。   That is, when the rotation shaft member 41 is rotated, a click feeling is obtained when the torque required for rotation changes abruptly. The position where the click occurs is configured to occur when the transition starts from the closed state to the second open state and when the transition to the second open state is completed. When the user shifts from the closed state to the second open state, the user can obtain a click feeling when the transition starts and when the transition is completed. Also, a click feeling can be obtained at the start of transition and when the transition is completed when transitioning from the second open state to the closed state.

平坦部材４６は、第１ばね部材４４を構成する皿ばねの角部４４Ａが止め輪４７と直接、当接させないようにするために設けられる。また、穴６９を有し、穴６９に細径部５１が挿通する。   The flat member 46 is provided so that the corner portion 44 </ b> A of the disc spring constituting the first spring member 44 does not directly contact the retaining ring 47. Further, the hole 69 is provided, and the small diameter portion 51 is inserted into the hole 69.

皿ばねの角部４４Ａは円状であるが、止め輪４７は切り欠かれた開口部７０を有するため、開口部７０で皿ばねの角部４４Ａが脱落して傾斜するなど、所定の撓みが発生しなくなることを回避する。   The disc spring corner 44A has a circular shape, but the retaining ring 47 has a cutout opening 70, so that the disc spring corner 44A falls off and tilts at the opening 70, so that a predetermined deflection occurs. Avoid being lost.

ここで、図５を用いて、平坦部材４６の作用を説明する。図５（ａ）のように、平坦部材４６があるので、第１ばね部材４４における止め輪４７に最も近く配置される皿ばねの内径側の角部４４Ａは、全周が平坦部材４６の第１平坦面４６Ａと当接する。皿ばねの外径側の角部４４Ｂを止め輪４７に最も近く配置した場合でも、角部４４Ａ全周が平坦部材４６の第１平坦面４６Ａと当接する。一方、図５（ｂ）のように、平坦部材４６がないと、第１ばね部材４４における止め輪４７に最も近く配置される皿ばねの内径側の角部４４Ａの一部は、止め輪４７の開口部７０に陥落する。そのため、図５（ｂ）に示すように、皿ばねが傾いてしまう。皿ばねが傾くと、複数枚重なった第１ばね部材４４は、所定の撓みが発生しない。そのため、所定の荷重でカム部材４３を付勢しないので、回動軸部材４１と共に回動するカム部材４３は、所定の摺動トルクや所望のクリックを発生しない。   Here, the operation of the flat member 46 will be described with reference to FIG. As shown in FIG. 5A, since the flat member 46 is provided, the corner 44A on the inner diameter side of the disc spring arranged closest to the retaining ring 47 in the first spring member 44 has the entire circumference of the flat member 46. 1 Abuts with the flat surface 46A. Even when the corner portion 44B on the outer diameter side of the disc spring is disposed closest to the retaining ring 47, the entire circumference of the corner portion 44A contacts the first flat surface 46A of the flat member 46. On the other hand, as shown in FIG. 5B, if there is no flat member 46, a part of the corner portion 44 </ b> A on the inner diameter side of the disc spring arranged closest to the retaining ring 47 in the first spring member 44 is the retaining ring 47. Falls into the opening 70 of the. Therefore, as shown in FIG.5 (b), a disc spring will incline. When the disc spring is tilted, the plurality of first spring members 44 that overlap each other do not generate a predetermined deflection. Therefore, the cam member 43 is not urged by a predetermined load, so that the cam member 43 that rotates together with the rotation shaft member 41 does not generate a predetermined sliding torque or a desired click.

従って、第２ヒンジ２９は、平坦部材４６を設けたので、第１ばね部材４４が所定の撓みを生じることで回動軸部材４１に安定したトルクを発生させられるなど、生じるトルクの安定性を犠牲にすることなくばらつきを最小化しながら小型化を図っている。   Therefore, since the second hinge 29 is provided with the flat member 46, the first spring member 44 can generate a stable torque to the rotating shaft member 41 by causing the first spring member 44 to bend a predetermined amount. Miniaturization is achieved while minimizing variations without sacrificing.

なお、第１ばね部材４４が生じる付勢力を、止め輪４７における第１ばね部材４４側の面に対して垂直に力を受けるようにすれば、第１ばね部材４４に所定の撓みを発生させることができるなど、適宜、第１ばね部材４４と止め輪４７の間に、第１ばね部材４４側を向く側面と止め輪４７側を向く側面が、ともに止め輪４７と平行にする部品を、適宜、追加してもよい。   If the urging force generated by the first spring member 44 is received perpendicularly to the surface of the retaining ring 47 on the first spring member 44 side, a predetermined deflection is generated in the first spring member 44. Where appropriate, a part between the first spring member 44 and the retaining ring 47, the side surface facing the first spring member 44 side and the side surface facing the retaining ring 47 side are both parallel to the retaining ring 47, You may add suitably.

平坦部材４６の第１平坦部４６Ａ、第１平坦部４６Ａの裏面であって第１平坦部４６Ａと平行な第２平坦部４６Ｂと隣接しながら当接する止め輪４７、止め輪４７が取り付けられる溝５２であって第１ばね部材４４に対して遠方の端面５２Ａ、カム部材４３の第１凹凸面６７の反対面は、全て平行で、かつ回動軸部材４１の軸心ｂに垂直にしている。そのため、第１ばね部材４４おける止め輪４７に最も近く配置される皿ばねの内径側の角部４４Ａは、第１平坦面４６Ａと当接するので、第１ばね部材４４の反力は細径部５１のスラスト方向に作用させることができる。従って、第１ばね部材４４による付勢力は、端面５２Ａと第１凹凸面６７の反対面に垂直（軸心ｂに平行）に作用させる。
少なくとも、第１凹凸面６７の裏面と、端面５２Ａと、が軸心ｂに対して直角であって、第１平坦部４６Ａと第１凹凸面６７の裏面が、第１ばね部材４４の角部がすべて当接する平面にすれば、平坦部材４６と止め輪４７との間にばねの付勢力を伝達する部品を介在させれば、第１ばね部材４４は所定の付勢力を発生し、回動軸部材４１は所定トルクで回動し、カム部材４３は所望のクリックを発生する。 The first flat portion 46A of the flat member 46, a retaining ring 47 which contacts the second flat portion 46B which is the back surface of the first flat portion 46A and is parallel to the first flat portion 46A, and a groove to which the retaining ring 47 is attached. 52, the end surface 52A far from the first spring member 44 and the opposite surface of the cam member 43 from the first uneven surface 67 are all parallel and perpendicular to the axis b of the rotary shaft member 41. . Therefore, the corner 44A on the inner diameter side of the disc spring disposed closest to the retaining ring 47 in the first spring member 44 abuts on the first flat surface 46A, so that the reaction force of the first spring member 44 is a small diameter portion. 51 in the thrust direction. Therefore, the urging force by the first spring member 44 is applied perpendicularly (parallel to the axis b) to the opposite surface of the end surface 52A and the first uneven surface 67.
At least the back surface of the first uneven surface 67 and the end surface 52A are perpendicular to the axis b, and the first flat portion 46A and the back surface of the first uneven surface 67 are corner portions of the first spring member 44. If the flat surface is in contact with the flat member 46 and the retaining ring 47, the first spring member 44 generates a predetermined urging force and rotates. The shaft member 41 rotates with a predetermined torque, and the cam member 43 generates a desired click.

なお、上述したように、第１ばね部材４４における止め輪４７に最も近く配置される皿ばねの内径側の角部４４Ａは、平坦部材４６に当てなければならないため、細径部５１外形に対する穴６９との隙間（ガタ）は、組み立て性も考慮しながら設定しなければならない。すなわち、ガタが最大になっても、第１ばね部材４４における止め輪４７に最も近く配置される皿ばねの内径側の角部４４Ａに確実に当接するように、適宜設定すればよい。   As described above, the corner portion 44A on the inner diameter side of the disc spring disposed closest to the retaining ring 47 in the first spring member 44 must be brought into contact with the flat member 46. The gap (backlash) with 69 must be set in consideration of assembly. That is, even when the backlash is maximized, it may be set as appropriate so as to surely contact the corner 44A on the inner diameter side of the disc spring disposed closest to the retaining ring 47 in the first spring member 44.

止め輪４７は、開口部７０が広がる変形をしながら溝部５２に取り付けると、第１ばね部材４４は所定量だけ撓み、カム部材４３を保持部材４２に向けて付勢する。   When the retaining ring 47 is attached to the groove 52 while the opening 70 is deformed to expand, the first spring member 44 bends by a predetermined amount and biases the cam member 43 toward the holding member 42.

すなわち、止め輪４７の開口部７０が広がる変形をしながら溝部５２に取り付けられると、保持部材４２は、カム部材４３と第１ばね部材４４と止め輪４７と平坦部材４６とを間に挟むようにして保持する。所謂、片持ち状態ではなく、両端支持状態となる。これにより、保持部材４２は、細径部５１を保持する保持長Ｌ１（図２に図示した、第１凹凸面６７の裏面から端面５２Ａまでの長さ）を大きくすることができるので、保持部材４２に対する回動軸部材４１の振れを小さくしている。   That is, when the opening 70 of the retaining ring 47 is attached to the groove 52 while being deformed to expand, the holding member 42 sandwiches the cam member 43, the first spring member 44, the retaining ring 47, and the flat member 46 therebetween. Hold. It is not in a so-called cantilever state but in a state where both ends are supported. Accordingly, the holding member 42 can increase the holding length L1 (the length from the back surface of the first uneven surface 67 to the end surface 52A shown in FIG. 2) for holding the small-diameter portion 51. The swing of the rotating shaft member 41 with respect to 42 is reduced.

溝部５２に止め輪４７が取り付けられた状態では、第１ばね部材４４の付勢力により太径部５３が第２貫通穴６１の入り口に付勢当接され、平坦部材４６が止め輪４７に付勢当接されるので、細径部５１は、保持部材４２に対して回動軸部材４１のスラスト方向に微動しない（ガタが無い）状態で取り付けられる。   In a state where the retaining ring 47 is attached to the groove portion 52, the large diameter portion 53 is urged and abutted against the entrance of the second through hole 61 by the urging force of the first spring member 44, and the flat member 46 is attached to the retaining ring 47. Because of the force contact, the small-diameter portion 51 is attached to the holding member 42 in a state in which it does not slightly move in the thrust direction of the rotation shaft member 41 (no play).

移動部材４８は、突出部７２と、脚部７３と、円柱部７４と、を有する。第２ばね部材（コイルばね）４９の中に円柱部７４が差し込まれながら、保持部材４２の収容部６３に収容される。突出部７２は、第２ばね部材により付勢される方向の先端に形成されている。移動部材４８が収容部６３に収容された状態では、第２ばね部材４９により、図４に示す矢印Ｃ方向に付勢され、突出部７２が保持部材４２の収容部６３より突出する。突出した突出部７２は、収容部６３の入り口に形成された第２突起部６６と隣接する。   The moving member 48 includes a protruding portion 72, a leg portion 73, and a cylindrical portion 74. The cylindrical portion 74 is inserted into the second spring member (coil spring) 49 and is accommodated in the accommodating portion 63 of the holding member 42. The protrusion 72 is formed at the tip in the direction urged by the second spring member. In a state where the moving member 48 is accommodated in the accommodating portion 63, the second spring member 49 is urged in the direction of arrow C shown in FIG. 4, and the protruding portion 72 protrudes from the accommodating portion 63 of the holding member 42. The protruding portion 72 that protrudes is adjacent to the second protruding portion 66 formed at the entrance of the accommodating portion 63.

軸受部材５０は、下筐体３と連結部４に跨るように設けられ、下筐体３に対しては固定され、連結部４に対しては回動可能に取り付けられる。軸受部材５０は、第４貫通穴７５と、先端側に形成された引掛け部７６と、を有し、引掛け部７６は本体部が第１開状態のときに脚部７３と当接して、移動部材４８を、図４に示す矢印Ｃ方向とは反対側へ移動させる。   The bearing member 50 is provided so as to straddle the lower housing 3 and the connecting portion 4, is fixed to the lower housing 3, and is rotatably attached to the connecting portion 4. The bearing member 50 includes a fourth through hole 75 and a hook portion 76 formed on the distal end side. The hook portion 76 contacts the leg portion 73 when the main body portion is in the first open state. The moving member 48 is moved to the side opposite to the arrow C direction shown in FIG.

次に、図６を用いて、連結部４について、説明する。下筐体３の一端側（連結部４が装着される側）には、端部（図６では左端側）に略円筒状の第１ヒンジ装着部７７、略中央部に略円筒状のガイド部７８が形成されている。   Next, the connection part 4 is demonstrated using FIG. On one end side (the side on which the connecting portion 4 is mounted) of the lower housing 3, a substantially cylindrical first hinge mounting portion 77 is provided at the end portion (left end side in FIG. 6), and a substantially cylindrical guide is provided at the substantially central portion. A portion 78 is formed.

連結部４は、第１保持部７９と、第２保持部８０と、第１保持部７９と第２保持部８０を接続する接続部８１と、からなる。第１保持部７９は、第１ヒンジ装着部７７とガイド部７８の間に配置される。   The connecting portion 4 includes a first holding portion 79, a second holding portion 80, and a connection portion 81 that connects the first holding portion 79 and the second holding portion 80. The first holding part 79 is disposed between the first hinge mounting part 77 and the guide part 78.

接続部８１はガイド部７８の外側に配置され、第１保持部７９と第２保持部８０とがガイド部７８の外側から挟み込むように形成されている。接続部８１の内部に第２ヒンジ２９が装着される第２ヒンジ装着部８２と、を有する。第２ヒンジ装着部８２は、連結部４に対して第２ヒンジ２９の第３ねじ部６４を先頭に、本体部１が閉状態のときの上筐体２側から下筐体３側への方向へと組み付けられる。第２ヒンジ２９が連結部４内に収容された後、ねじ８３が第３ねじ部６４に螺着して固定される。   The connection portion 81 is disposed outside the guide portion 78, and is formed so that the first holding portion 79 and the second holding portion 80 are sandwiched from the outside of the guide portion 78. And a second hinge mounting portion 82 to which the second hinge 29 is mounted. The second hinge mounting portion 82 starts from the third screw portion 64 of the second hinge 29 with respect to the connecting portion 4, and moves from the upper housing 2 side to the lower housing 3 side when the main body 1 is closed. Assembled in the direction. After the second hinge 29 is accommodated in the connecting portion 4, the screw 83 is screwed and fixed to the third screw portion 64.

第１ヒンジ２８は、第１ヒンジ装着部７７に回動不能に保持される第１固定部２８Ａと、第１保持部７９に回動不能に保持される第２固定部２８Ｂと、を有する。下筐体３に対して上筐体２が、図６に示す軸心ａを中心に矢印Ａ方向に回動したとき、第１固定部２８Ａに対して第２固定部２８Ｂが回動し、内蔵されたクリック発生部（図示せず）とトルク発生部（図示せず）により、所望の摺動トルクやクリックが得られるようになっている。   The first hinge 28 includes a first fixing portion 28A that is non-rotatably held by the first hinge mounting portion 77, and a second fixing portion 28B that is non-rotatably held by the first holding portion 79. When the upper housing 2 rotates in the direction of arrow A about the axis a shown in FIG. 6 with respect to the lower housing 3, the second fixing portion 28B rotates with respect to the first fixing portion 28A. A desired sliding torque and click can be obtained by a built-in click generator (not shown) and torque generator (not shown).

図７乃至図９に示す符号は図６に示す符号と同じなので、図７乃至図９の符号の説明は省く。なお、ケーブル３２は、複数本から構成されているが、図７乃至図９では、まとめて１本のケーブルとして図示している。   The reference numerals shown in FIGS. 7 to 9 are the same as the reference numerals shown in FIG. The cable 32 is composed of a plurality of cables. However, in FIGS. 7 to 9, the cables 32 are collectively illustrated as one cable.

次に、図２及び図１０を用いて、ケーブル３２について説明する。図２において、ケーブル３２は、複数本から構成される。図示しないが、１本のケーブル３２は、複数の中心導体と、中心導体の外部に設けられた第１絶縁層と、第１絶縁層の外部に設けられた外部導体と、外部導体の外部に設けられた第２絶縁層とからなる同軸細線である。複数本のケーブル３２は、ポリエステルなどからなる繊維で製紐された後、中空状に形成された管部材３３の中に通される。   Next, the cable 32 will be described with reference to FIGS. 2 and 10. In FIG. 2, the cable 32 includes a plurality of cables. Although not shown, one cable 32 includes a plurality of central conductors, a first insulating layer provided outside the central conductor, an external conductor provided outside the first insulating layer, and outside the external conductor. It is a coaxial thin line consisting of the provided second insulating layer. The plurality of cables 32 are stringed with fibers made of polyester or the like, and then passed through a tube member 33 formed in a hollow shape.

管部材３３は、断面形状が容易に変形可能であり、かつ、表面と内面がともに低摩擦性を備えさせるため、繊維材で形成している。例えば、ゴム材で管部材３３を形成した場合について説明する。本体部１を開閉した場合、の管部材３３は周囲の他の構成部品（連結部４の内面や回動軸部材４１の第１貫通穴５９など）と擦れるため、磨耗が生じ易い。このとき、ゴム材の表面は摩擦抵抗が大きいため、擦れると磨耗が生じ、穴が開いてしまう。そのため、一般的に、ゴム製管部材の周囲に保護テープを巻く場合がある。その結果、コストアップを招きやすい。   The pipe member 33 is formed of a fiber material so that the cross-sectional shape can be easily deformed, and both the surface and the inner surface have low friction. For example, a case where the tube member 33 is formed of a rubber material will be described. When the main body 1 is opened and closed, the pipe member 33 is rubbed against other surrounding components (such as the inner surface of the connecting portion 4 and the first through hole 59 of the rotating shaft member 41), and therefore wear easily occurs. At this time, since the surface of the rubber material has a large frictional resistance, abrasion occurs and the hole is opened. Therefore, in general, a protective tape may be wound around the rubber tube member. As a result, cost is likely to increase.

管部材３３は、中空部分に複数本のケーブル３２を通した状態で第１貫通穴５９内に配置される。管部材３３の片端側は、第１貫通穴５９から脱出後に上筐体２内へと導かれる。管部材３３の他端側は、第１貫通穴５９から脱出後、略９０度に曲げられ、軸受部材５０の第４貫通穴７５を通って下筐体３側へと導かれる。複数本のケーブル３２が９０度に曲げられた部位近傍において、例えば、複数本のケーブル３２が粘着性のテープなどで束ねられていれば、束ねられた複数本のケーブル３２は曲がりづらくなり、結果的に、形成される曲率Ｒが大きくなってしまう。曲率Ｒが大きくても、連結部４内に束ねられた複数本のケーブル３２を配線するためには、第１貫通穴５９から連結部４の内面４Ａまでの距離Ｌ２も大きくしなければならないため、結果的に、連結部４及び本体部１全体を大きくしなければならない。   The tube member 33 is disposed in the first through hole 59 in a state where a plurality of cables 32 are passed through the hollow portion. One end side of the pipe member 33 is guided into the upper housing 2 after escaping from the first through hole 59. The other end side of the pipe member 33 is bent at about 90 degrees after escape from the first through hole 59 and is guided to the lower housing 3 side through the fourth through hole 75 of the bearing member 50. In the vicinity of the portion where the plurality of cables 32 are bent at 90 degrees, for example, if the plurality of cables 32 are bundled with an adhesive tape or the like, the bundled cables 32 are difficult to bend. Therefore, the curvature R to be formed is increased. Even if the curvature R is large, the distance L2 from the first through hole 59 to the inner surface 4A of the connecting portion 4 must be increased in order to route a plurality of cables 32 bundled in the connecting portion 4. As a result, the connecting part 4 and the main body part 1 as a whole must be enlarged.

本実施形態では、管部材３３の中空部分に複数本のケーブル３２を束線せずに通しているのみである。そのため、複数本のケーブル３２は、図１０（ａ）に示すように、第１貫通穴５９の中では略円状に配列されて並走する。管部材３３も直線状に配置される。ここで、管部材３３の直径をＤとすると、管部材３３の直径は、前述した第１貫通穴５９から連結部４の内面４Ａまでの距離Ｌ２よりも大きい（Ｄ＞Ｌ２）の関係である。また、第１貫通穴５９から複数本のケーブル３２が脱出直後は、第１貫通穴５９から連結部４の内面４Ａまでの距離Ｌ２の空間を通すので、図１０（ｂ）のようにケーブル３２は略楕円状となる。管部材３３も略楕円状に変形する。管部材３３の短軸側は、ほぼ距離Ｌ２と等しくなる。   In the present embodiment, the plurality of cables 32 are only passed through the hollow portion of the tube member 33 without being bundled. Therefore, as shown in FIG. 10A, the plurality of cables 32 are arranged in a substantially circular shape and run in parallel in the first through hole 59. The pipe member 33 is also arranged linearly. Here, when the diameter of the pipe member 33 is D, the diameter of the pipe member 33 is larger than the distance L2 from the first through hole 59 to the inner surface 4A of the connecting portion 4 (D> L2). . Further, immediately after the plurality of cables 32 have escaped from the first through hole 59, a space of a distance L2 from the first through hole 59 to the inner surface 4A of the connecting portion 4 is passed, so the cable 32 as shown in FIG. Is substantially elliptical. The tube member 33 is also deformed into a substantially elliptic shape. The short axis side of the tube member 33 is substantially equal to the distance L2.

上述のように、複数本のケーブル３２は断面が変形可能な管部材３３内に設け、９０度に曲げた後に管部材３３の直径より狭い空間に配置したので、曲げた場合に生成する曲率を小さくすることができる。よって、配線スペースを小さくすることができるので、本体部１の大型化が回避できる。   As described above, the plurality of cables 32 are provided in the pipe member 33 whose cross section is deformable, and are arranged in a space narrower than the diameter of the pipe member 33 after being bent at 90 degrees. Can be small. Therefore, since the wiring space can be reduced, an increase in the size of the main body 1 can be avoided.

次に、図１を用いて、本発明の実施形態の開閉式携帯電話の動作について説明する。使用者は、使用モードに合わせて、閉状態（図１（ａ））、第１開状態（図１（ｂ））、第２開状態（図１（ｃ））を選択する。   Next, the operation of the openable mobile phone according to the embodiment of the present invention will be described with reference to FIG. The user selects a closed state (FIG. 1A), a first open state (FIG. 1B), and a second open state (FIG. 1C) according to the use mode.

本体部１に電源が投入されると、本体部１は、受信待受動作を開始する。操作部１４を操作することで、カメラモードやＴＶ受信モードに切り替えることができる。   When the main unit 1 is turned on, the main unit 1 starts a reception standby operation. By operating the operation unit 14, the camera mode and the TV reception mode can be switched.

カメラモードにおいては、第２カメラ部１５の起動によって、モードが切り替わる。第２カメラ部１５を起動させると、第２カメラ部１５の撮影画像を第１表示部７に表示させることができ、撮像画像を保存したいた場合には情報記録部２５に記録させることができる。   In the camera mode, the mode is switched by the activation of the second camera unit 15. When the second camera unit 15 is activated, a photographed image of the second camera unit 15 can be displayed on the first display unit 7, and when the captured image is stored, it can be recorded in the information recording unit 25. .

ＴＶ受信モードにおいては、ＴＶ放送を受信すれば、第１表示部７でＴＶ視聴が可能になる。ＴＶ画像は横長画面であるため、横長画面で視聴することが望ましい。この場合、下筐体３に対して上筐体２を、図１（ｃ）に示す軸心ｂを中心に矢印Ｂ方向に開いて本体部１を第２開状態にし、操作部１４を手前側に持つと横長画面として第１表示部７を見ることができるなど、ＴＶ視聴に好適な態様となる。   In the TV reception mode, when the TV broadcast is received, the first display unit 7 can watch TV. Since the TV image is a landscape screen, it is desirable to view it on the landscape screen. In this case, the upper housing 2 is opened with respect to the lower housing 3 in the direction of arrow B about the axis b shown in FIG. When it is held on the side, the first display unit 7 can be viewed as a horizontally long screen, which is suitable for TV viewing.

なお、各モード下において着信した場合、着信を報知するために、スピーカ６から着信音が出力される。このとき、上筐体２を、図１（ｂ）に示す軸心ａを中心に矢印Ａ方向に回動して本体部１を第１開状態にし、所定の操作を行うと受話できる。使用者の音声はマイクロフォン１３から出力される。   When an incoming call is received under each mode, a ring tone is output from the speaker 6 in order to notify the incoming call. At this time, the upper housing 2 can be received by rotating the upper housing 2 in the direction of arrow A about the axis a shown in FIG. 1B to bring the main body 1 into the first open state and performing a predetermined operation. The user's voice is output from the microphone 13.

終話すると、受話直前のモードが再開する。   When the talk ends, the mode immediately before the call resumes.

携帯時には、図１（ａ）に示す閉状態が好適である。   At the time of carrying, the closed state shown in FIG.

次に、図６を用いて、本体部１が開閉するときの動作について、説明する。図６において、本体部１は閉状態なので、軸受部材５０の引掛け部７６は移動部材４８の脚部７３と当接して、移動部材４８を、図４に示す矢印Ｃ方向とは反対方向へ移動させる（図６では、紙面奥行き方向）。図６では、移動部材４８は収容部６３の中に埋没している状態を示している。移動部材４８の突出部７２は、回動軸部材４１の太径部５３の切欠き面６０と対面していないので、回動軸部材４１は、図６に示す軸心ｂを中心に矢印Ｂ方向に回動できるようになっている。   Next, the operation when the main body 1 opens and closes will be described with reference to FIG. In FIG. 6, since the main body 1 is in a closed state, the hooking portion 76 of the bearing member 50 abuts on the leg portion 73 of the moving member 48 to move the moving member 48 in the direction opposite to the arrow C direction shown in FIG. It is moved (in FIG. 6, the depth direction of the paper). FIG. 6 shows a state in which the moving member 48 is buried in the accommodating portion 63. Since the projecting portion 72 of the moving member 48 does not face the notch surface 60 of the large-diameter portion 53 of the rotating shaft member 41, the rotating shaft member 41 has an arrow B centering on the axis b shown in FIG. It can be rotated in the direction.

次に、図７、図８を用いて、本体部１が図１（ａ）に示す閉状態から、下筐体３に対して上筐体２を軸心ｂを中心に矢印Ｂ方向に回動して、図１（ｃ）に示す第２開状態になるときに動作について、説明する。図７は、図６の状態（閉状態）から回動軸部材４１が、軸心ｂを中心に矢印Ｂ方向に約１７０度回動した状態（第２開状態）を示している。回動軸部材４１の太径部５３は、移動部材４８の突出部７２の先端側を通過して、第２開状態となる。切欠き面６０が保持部材４２に形成された第１突起部６５と当接することで、所定量の角度（本実施形態では１７０度）だけしか回動できないようになっている。また、第２開状態では、太径部５３が移動部材４８の突出部７２の一部（先頭部分）を覆う。   Next, referring to FIGS. 7 and 8, the main body 1 rotates from the closed state shown in FIG. 1A with respect to the lower housing 3 in the direction of arrow B about the axis b. The operation when moving to the second open state shown in FIG. 1 (c) will be described. FIG. 7 shows a state (second open state) in which the rotary shaft member 41 is rotated about 170 degrees in the direction of arrow B about the axis b from the state of FIG. 6 (closed state). The large-diameter portion 53 of the rotating shaft member 41 passes through the distal end side of the projecting portion 72 of the moving member 48 and enters the second open state. The notch surface 60 is in contact with the first protrusion 65 formed on the holding member 42 so that it can be rotated only by a predetermined angle (170 degrees in this embodiment). Further, in the second open state, the large-diameter portion 53 covers a part (leading portion) of the protruding portion 72 of the moving member 48.

すなわち、軸受部材５０の引掛け部７６が移動部材４８の脚部７３と当接して、軸受部材５０は、第２ばね部材４９の付勢力に抗して移動部材４８を矢印Ｃとは反対方向に移動させて、突出部７２を収容部６３の中に引き込んでいる。そして、回動軸部材４１の太径部５３は、移動部材４８の突出部７２における矢印Ｃ側先端を覆うように構成している。   That is, the hook portion 76 of the bearing member 50 contacts the leg portion 73 of the moving member 48, and the bearing member 50 moves the moving member 48 in the direction opposite to the arrow C against the urging force of the second spring member 49. The projecting portion 72 is drawn into the housing portion 63. And the large diameter part 53 of the rotating shaft member 41 is comprised so that the arrow C side front-end | tip in the protrusion part 72 of the moving member 48 may be covered.

図８は、図７の部分拡大図である。図８において、第２開状態では、太径部５３が移動部材４８の突出部７２の一部（先頭部分）を覆い、覆われた部位を、斜線部７２Ａで示す。   FIG. 8 is a partially enlarged view of FIG. In FIG. 8, in the second open state, the large-diameter portion 53 covers a part (leading portion) of the protruding portion 72 of the moving member 48, and the covered portion is indicated by a hatched portion 72A.

次に、図９を用いて、軸受部材５０の動作について説明する。図９は、図６に示す閉状態から下筐体３に対して上筐体２を軸心ｂを中心に矢印Ｂ方向に回動させず、下筐体３に対して上筐体２が軸心ａを中心に矢印Ａ方向に回動した状態と同じであって、上筐体２に対して下筐体３が軸心ａを中心に矢印Ａ方向とは反対方向に回動した状態を示している。   Next, the operation of the bearing member 50 will be described with reference to FIG. 9 does not rotate the upper housing 2 in the direction of the arrow B about the axis b with respect to the lower housing 3 from the closed state shown in FIG. A state in which the lower housing 3 is rotated with respect to the upper housing 2 in the direction opposite to the direction of the arrow A with respect to the upper housing 2 in the same manner as the state of rotation in the direction of the arrow A around the shaft center a. Is shown.

軸受部材５０は、下筐体３のガイド部７８に回動不能に保持されるとともに連結部４の第２保持部８０に対しては回動可能に保持されているので、下筐体３に対して上筐体２が軸心ａを中心に矢印Ａ方向に所定角度だけ回動すると、軸受部材５０は、連結部４に対して軸心ａを中心に矢印Ａ方向とは反対方向に所定角度だけ回動する。その結果、軸受部材５０の引掛け部７６が脚部７３から離遠する。軸受部材５０が離遠した移動部材４８は、第２ばね部材４９の付勢により、突出部７２が保持部材４２から突出する方向に移動する。突出後の突出部７２は切欠き面６０と当接するので、上筐体２は軸心ｂを中心に矢印Ｂ方向へは回動しない。   Since the bearing member 50 is non-rotatably held by the guide portion 78 of the lower housing 3 and is rotatably held by the second holding portion 80 of the connecting portion 4, On the other hand, when the upper housing 2 is rotated by a predetermined angle in the direction of arrow A about the axis a, the bearing member 50 is predetermined in the direction opposite to the direction of arrow A about the axis a with respect to the connecting portion 4. Rotate by an angle. As a result, the hook portion 76 of the bearing member 50 moves away from the leg portion 73. The moving member 48 separated from the bearing member 50 moves in a direction in which the protruding portion 72 protrudes from the holding member 42 due to the biasing force of the second spring member 49. Since the projecting portion 72 after projecting comes into contact with the notch surface 60, the upper housing 2 does not rotate in the direction of arrow B about the axis b.

すなわち、軸受部材５０は、本体部１の筐体態様に応じて、第２ばね部材４９による付勢力に抗して移動部材４８の位置を制御するものである。また、突出部７２は、第２突起部６６と隣接しているので、上筐体２を軸心ｂを中心に矢印Ｂ方向とは反対方向に故意や不意に回動させると、突出部７２は切欠き面６０と第２突起部６６の両方に当接する。このとき、大きな力当接すると、突出部７２が破損してしまうので、切欠き面６０から力を受けても突出部７２が破損しないように、第２突起部６６と当接する構成にしている。   That is, the bearing member 50 controls the position of the moving member 48 against the urging force of the second spring member 49 according to the housing mode of the main body 1. Further, since the protrusion 72 is adjacent to the second protrusion 66, when the upper housing 2 is intentionally or unexpectedly rotated around the axis b in the direction opposite to the arrow B direction, the protrusion 72 is provided. Is in contact with both the notch surface 60 and the second protrusion 66. At this time, if a large force is brought into contact, the projecting portion 72 is damaged, so that the projecting portion 72 is not damaged even if a force is received from the notch surface 60. .

すなわち、突出部７２は、収容部６３から突出した状態では、切欠き面６０から力を受けると、所謂、片持ちばり状態となり、曲げモーメートが生じる。この曲げモーメントが作用しても破損しないようにするためには、移動部材４８を大きくしたり許容応力が大きい材料を使用するのがよいが、反面、大型化やコストアップを招いてしまう。   That is, when the protruding portion 72 protrudes from the accommodating portion 63 and receives a force from the notched surface 60, the protruding portion 72 is in a so-called cantilever state, and bending moment is generated. In order to prevent damage even when this bending moment is applied, it is preferable to enlarge the moving member 48 or to use a material having a large allowable stress. However, on the other hand, it increases the size and costs.

そこで、移動部材４８の力を受ける面とは反対面を第２突起部６６に当接することで、曲げモーメントが生じないようにすることができるので、移動部材４８の大型化、コストアップを回避している。すなわち、突出部７２に加わる力は、曲げられる力から圧縮される力に代わる。圧縮力に耐え得る材料は豊富なので、移動部材４８は汎用材料で構成できる。   In view of this, the surface opposite to the surface that receives the force of the moving member 48 is brought into contact with the second protrusion 66, so that a bending moment can be prevented from occurring, thereby avoiding an increase in size and cost of the moving member 48. is doing. That is, the force applied to the protrusion 72 is replaced by a force compressed from a bending force. Since there are abundant materials that can withstand the compressive force, the moving member 48 can be made of a general purpose material.

次に、図１（ｄ）を用いて、第３開状態について説明する。使用者が、図１（ｃ）に示す第２開状態から、下筐体３に対して上筐体２を軸心ａを中心に矢印Ａ方向に回動させてしまう誤操作を行った場合、移動部材４８の脚部７３から軸受部材５０の引掛け部７６が離遠する。離遠すると、第２ばね部材４９の付勢により、移動部材４８は矢印Ｃ方向に移動しようとするが、移動部材４８の一部（先頭部分）は、太径部５３に覆われた状態なので、矢印Ｃ方向への移動はできない。仮に、移動部材４８の先頭が太径部５３に覆われていなければ、移動部材４８は矢印Ｃ方向へ移動する。本体部１の態様としては、下筐体３に対して上筐体２が軸心ａを中心に矢印Ａ方向及び軸心ｂを中心に矢印Ｂ方向へともに回動した状態であり、図１（ｄ）に示す本体部１の状態を、第３開状態と称することにする。第３開状態では、第１表示部７は使用者側を向いていないので、第１表示部７に表示される表示情報を見ることができない。そこで、使用者が第３開状態を解消するためには、上筐体２をＡ方向及びＢ方向のいずれか一方の方向の反対側へ回動させるだけで済むとよい。Ａ方向及びＢ方向のいずれか一方の方向へのみ回動する構成にすれば、使用者が誤って回動できない方向へ力を入れて、本体部１が破損してしまう場合がある。   Next, a 3rd open state is demonstrated using FIG.1 (d). When the user performs an erroneous operation of rotating the upper housing 2 in the direction of arrow A about the axis a with respect to the lower housing 3 from the second open state shown in FIG. The hook portion 76 of the bearing member 50 is separated from the leg portion 73 of the moving member 48. When moving away, the moving member 48 tries to move in the direction of arrow C due to the urging of the second spring member 49, but a part (leading portion) of the moving member 48 is covered by the large-diameter portion 53. , Movement in the direction of arrow C is not possible. If the leading end of the moving member 48 is not covered by the large-diameter portion 53, the moving member 48 moves in the arrow C direction. As an aspect of the main body 1, the upper housing 2 is rotated with respect to the lower housing 3 in the direction of arrow A around the axis a and in the direction of arrow B around the axis b. The state of the main body 1 shown in (d) will be referred to as a third open state. In the third open state, since the first display unit 7 does not face the user side, display information displayed on the first display unit 7 cannot be seen. Therefore, in order for the user to cancel the third open state, it is only necessary to rotate the upper housing 2 to the opposite side of either the A direction or the B direction. If it is configured to rotate only in one of the A direction and the B direction, the main body 1 may be damaged by applying a force in a direction in which the user cannot accidentally rotate.

本実施形態のように、図１（ｄ）に示す第３開状態では、移動部材４８が太径部５３によって覆われており、移動部材４８が突出する方向へ移動できないようにしてあるので、第３開状態からは、上筐体２を軸心ａを中心に矢印Ａ方向とは反対方向、または軸心ｂを中心に矢印Ｂ方向とは反対方向のいずれか一方の方向へ回動すれば、第１開状態か第２開状態のいずれか一方の態様へと変化させることができる。第１開状態にすれば、移動部材５０が移動して突出部７２が突出し、前述したように、突出後の突出部７２は切欠き面６０と当接する。そのため、上筐体２は軸心ｂを中心に矢印Ｂ方向へは回動できない。よって、第２開状態から第３開状態へとは戻らない。   As in this embodiment, in the third open state shown in FIG. 1 (d), the moving member 48 is covered by the large-diameter portion 53 so that the moving member 48 cannot move in the protruding direction. From the third open state, the upper housing 2 is rotated in the direction opposite to the arrow A direction around the axis a or in the direction opposite to the arrow B direction around the axis b. For example, it can be changed to one of the first open state and the second open state. In the first open state, the moving member 50 moves and the protruding portion 72 protrudes, and the protruding portion 72 after protruding contacts the notch surface 60 as described above. Therefore, the upper housing 2 cannot rotate in the arrow B direction around the axis b. Therefore, the second open state does not return to the third open state.

以上より、保持部材４２は、回動軸部材４１の細径部５１を、連結部４の中では最大限長い距離Ｌ１で保持する構成としたので、回動軸部材４１に対するガタを小さくすることができる。外部から力が加わった場合でも、長い距離Ｌ１で保持しているので、ガタの増長も小さくできる。   As described above, since the holding member 42 is configured to hold the small-diameter portion 51 of the rotating shaft member 41 at the maximum distance L1 in the connecting portion 4, the backlash with respect to the rotating shaft member 41 is reduced. Can do. Even when a force is applied from the outside, since the distance L1 is maintained, the increase in play can be reduced.

また、第１開状態においては、移動部材４８が突出して太径部５３と当接した状態なので、上筐体２を軸心ｂを中心に矢印Ｂ方向に回動させようとしても回動しないようにすることができる。しかも、閉状態では、上筐体２を矢印Ｂ方向に回動させようとした場合には簡単に行える。このような本体部１において、使用者が誤って第３の開状態にしてしまった場合、第１開状態または第２開状態の何れにも容易に変態させることができ、第１開状態にした場合は第３開状態へ態様を変化することを防止するなど、使用者には使い勝手のよい端末を提供できる。   In the first open state, the moving member 48 protrudes and is in contact with the large-diameter portion 53. Therefore, even if the upper housing 2 is rotated in the direction of arrow B about the axis b, it does not rotate. Can be. Moreover, in the closed state, it can be easily performed when the upper housing 2 is to be rotated in the direction of the arrow B. In such a main body 1, if the user accidentally enters the third open state, it can be easily transformed into either the first open state or the second open state. In this case, it is possible to provide a user-friendly terminal for the user, such as preventing the mode from changing to the third open state.

すなわち、第１開状態から第３開状態へと変化しないように、第２ヒンジ内２９に本体部１の態様状態と連動する移動部材４８を設けたので、第１開状態で、上筐体２に頭部を当てて通話するときには、使用者の意図に反して上筐体が回動しないようになっている。   That is, since the moving member 48 interlocking with the state of the main body 1 is provided in the second hinge 29 so as not to change from the first open state to the third open state, When a call is made with the head placed on 2, the upper casing does not rotate against the user's intention.

また、上筐体２と下筐体３を電気的に接続する複数本のケーブル３２は、断面が変形可能な管部材３３に配線したので、配線スペースの省スペース化が可能となり、本体部１の大型化を回避する。   Further, since the plurality of cables 32 that electrically connect the upper housing 2 and the lower housing 3 are wired to the pipe member 33 whose cross section is deformable, the wiring space can be saved, and the main body 1 Avoid the increase in size.

なお・BR>A管部材３３を設けない場合、第２絶縁層が第２ヒンジ２９の第１貫通穴５９と直接触れる。回動軸部材４１が回動すると、第１貫通穴５９と第２絶縁層とに擦れが生じ、時には、外部導体を露出させてしまう場合がある。一般に、第２ヒンジ２９は、高剛性が求められるので、金属製材料から形成される。そのため、外部導体が露出してしまうと、回動軸部材４１と外部導体とが短絡し、中心導体に信号とともにノイズとして重送してしまう恐れがある。これを回避するためには、所望の厚みを有する第２絶縁層を形成するのが好ましいが、反面、ケーブル３２が曲がりづらくなってしまう。その結果、第１貫通穴５９の内径やＬ２を大きくしなければならない。そのため、省スペース化、第１貫通穴５９の小径化により第２ヒンジ２９の小形化を図る上では、ケーブル３２はテープによる束線をせず管部材３３に挿通させるのがよい。   When the BR> A pipe member 33 is not provided, the second insulating layer directly touches the first through hole 59 of the second hinge 29. When the rotation shaft member 41 rotates, rubbing occurs between the first through hole 59 and the second insulating layer, and sometimes the external conductor is exposed. In general, since the second hinge 29 is required to have high rigidity, the second hinge 29 is made of a metal material. For this reason, if the outer conductor is exposed, the rotating shaft member 41 and the outer conductor may be short-circuited and may be double-fed as noise to the center conductor. In order to avoid this, it is preferable to form the second insulating layer having a desired thickness, but on the other hand, the cable 32 is difficult to bend. As a result, the inner diameter and L2 of the first through hole 59 must be increased. Therefore, in order to save space and reduce the size of the second hinge 29 by reducing the diameter of the first through hole 59, the cable 32 is preferably inserted through the tube member 33 without being bundled with tape.

また、本実施形態では、本体部１が閉状態のときに軸受部材５０が移動部材４８と当接して、移動部材４８を矢印Ｃ方向とは反対方向へ移動させる制御をしたが、これに限らない。下筐体３に固定された部品、或は下筐体３の一部が軸受部材５０の代替として、移動部材４８の位置を制御するようにしてもよい。   In the present embodiment, the bearing member 50 is in contact with the moving member 48 when the main body 1 is in the closed state, and the moving member 48 is controlled to move in the direction opposite to the arrow C direction. Absent. A part fixed to the lower housing 3 or a part of the lower housing 3 may be used as an alternative to the bearing member 50 to control the position of the moving member 48.

また、本実施形態の第２ばね部材４９は圧縮ばねで構成し、本体部１が閉状態のときには、第２ばね部材４９のばね力に抗して移動部材４８を矢印Ｃとは反対方向へ移動させるようにしたが、必ずしもこの限りではない。例えば、第２ばね部材４９を引張りばねで構成し、引張りばねの力で突出部７２を矢印Ｃ方向とは反対方向に引っ張る。本体部１が閉状態及び第２開状態のときは、軸受部材５０や下筐体３の一部が、ばね力に抗して移動部材４８を矢印Ｃ方向へ移動させるようにしてもよい。   Further, the second spring member 49 of the present embodiment is constituted by a compression spring, and when the main body 1 is in a closed state, the moving member 48 is moved in the direction opposite to the arrow C against the spring force of the second spring member 49. Although it was made to move, it is not necessarily this limitation. For example, the 2nd spring member 49 is comprised with a tension spring, and the protrusion part 72 is pulled in the direction opposite to the arrow C direction with the force of a tension spring. When the main body 1 is in the closed state and the second open state, the bearing member 50 and a part of the lower housing 3 may move the moving member 48 in the arrow C direction against the spring force.

また、移動部材４８は、所謂、並進運動をする構成としたが、必ずしもこの限りではない。例えば、回転軸を備えさせ、第１位置では回動軸部材とは当接しないようにし、第２位置では回動軸部材と当接して回動規制をするように、回転軸を中心に回転運動によって移動させるようにしてもよい。   In addition, the moving member 48 is configured to perform a so-called translational movement, but this is not necessarily the case. For example, a rotation shaft is provided so that the rotation shaft member is not in contact with the rotation shaft member in the first position, and the rotation shaft is rotated about the rotation shaft so as to be in contact with the rotation shaft member and restrict rotation in the second position. You may make it move by an exercise | movement.

また、止め輪４７の周囲について詳述しなかったが、例えば、使用者が誤って本体部を落下させてしまった場合には、止め輪４７が溝部５２から抜けてしまうような衝撃力が作用する。こういう事態を想定して、連結部４内には、止め輪４１の開口部７０が広がらないように、止め輪４７外周に臨むリブ等を設けるとよい。   Although the details of the periphery of the retaining ring 47 have not been described in detail, for example, if the user accidentally drops the main body part, an impact force that causes the retaining ring 47 to come out of the groove part 52 acts. To do. Assuming such a situation, a rib or the like facing the outer periphery of the retaining ring 47 may be provided in the connecting portion 4 so that the opening 70 of the retaining ring 41 does not expand.

なお、前述した角部は全て直角に図示してあるが、部品製作上、曲面や平面が付与されたものであっても、同一のエッヂが第１平坦面に対して当接させる構造としてもよい。
また、太径部は回動軸部材と一体な構造として説明したが、別部材を装着して構成してもよい。 Although the above-mentioned corners are all shown at right angles, even if a curved surface or a flat surface is given for manufacturing the part, the same edge may be in contact with the first flat surface. Good.
Moreover, although the large diameter part was demonstrated as a structure integral with a rotating shaft member, you may comprise it by mounting | wearing another member.
