上記２軸ヒンジ装置が用いられた携帯電話機においては、送話ケース及び受話ケースとヒンジ本体とが第１、第２ヒンジ軸を介して単に回動可能に連結されているだけであるため、受話ケースを送話ケースに対して回動させるときに、受話ケースがヒンジ本体に対して回動するか、ヒンジ本体が送話ケースに対して回動するかが定まらない。つまり、ヒンジ本体と受話ケースとの回動順序が一定に定まっていない。このため、受話ケースを開閉回動させる毎にヒンジ本体と受話ケースとの回動順序が変わってしまい、使用者に違和感を抱かせるという問題があった。   In the mobile phone using the biaxial hinge device, the transmitting case, the receiving case, and the hinge main body are merely pivotally connected via the first and second hinge shafts. When the case is rotated with respect to the transmission case, it cannot be determined whether the reception case rotates with respect to the hinge body or the hinge body rotates with respect to the transmission case. That is, the rotation order of the hinge body and the receiving case is not fixed. For this reason, every time the receiving case is opened and closed, the rotation order of the hinge main body and the receiving case changes, and there is a problem that the user feels uncomfortable.

The other end of the lower hinge 6A is inserted into the engagement hole 2g facing the first housing hole 5a. One end of the lower hinge 6B is inserted into the other of the two first accommodation holes 5a, 5a. The other end of the lower hinge 6B is inserted into the engagement hole 2g facing the other accommodation hole 5a. Accordingly, one side portion of the hinge body 5 in the short direction can be rotated to one end portion of the transmission case 2 via the pair of lower hinges 6A and 6B, which also rotates around the first rotation axis L1. It is linked movably.

二つの第２収容孔５ｂ，５ｂの一方には、上ヒンジ７Ａの一端部が挿入されている。この上ヒンジ７Ａの他端部は、一方の第２収容孔５ｂと対向する係合孔３ｇに挿入されている。二つの第２収容孔５ｂ，５ｂの他方には、上ヒンジ７Ｂの一端部が挿入されている。この上ヒンジ７Ｂの他端部は、他方の収容孔５ｂと対向する係合孔３ｇに挿入されている。これにより、ヒンジ本体５の短手方向における他側部が受話ケース３の一端部に一対の上ヒンジ７Ａ，７Ｂを介して回動可能に、それも第２回動軸線Ｌ２を中心として回動可能に連結されている。   One end of the upper hinge 7A is inserted into one of the two second accommodation holes 5b, 5b. The other end of the upper hinge 7A is inserted into the engagement hole 3g facing the second housing hole 5b. One end of the upper hinge 7B is inserted into the other of the two second accommodation holes 5b, 5b. The other end of the upper hinge 7B is inserted into the engagement hole 3g facing the other accommodation hole 5b. As a result, the other side portion of the hinge body 5 in the short direction can be turned to one end portion of the receiving case 3 via the pair of upper hinges 7A and 7B, and it is also turned around the second turning axis L2. Connected as possible.

ヒンジ本体５の一側部が下ヒンジ６Ａ，６Ｂを介して送話ケース２に回動可能に連結されるとともに、ヒンジ本体５の他側部が上ヒンジ７Ａ，７Ｂを介して回動可能に連結されることにより、受話ケース３が送話ケース２にヒンジ装置４を介して回動可能に連結されている。一対の下ヒンジ６Ａ，６Ｂのいずれか一方、及び一対の上ヒンジ７Ａ，７Ｂのいずれか一方については、単なる軸体を用い、ヒンジ本体５の一端部又は他端部を送話ケース２と受話ケース３とにそれぞれ軸体を介して回動可能に連結してもよい。   One side of the hinge body 5 is pivotably connected to the transmission case 2 via the lower hinges 6A and 6B, and the other side of the hinge body 5 is pivotable via the upper hinges 7A and 7B. By being connected, the reception case 3 is rotatably connected to the transmission case 2 via the hinge device 4. As for either one of the pair of lower hinges 6A and 6B and one of the pair of upper hinges 7A and 7B, a simple shaft body is used, and one end or the other end of the hinge body 5 is connected to the transmitting case 2 and the receiving end. You may connect with case 3 so that rotation is possible via a shaft, respectively.

次に、上記下ヒンジ６Ａ，６ Ｂ及び上ヒンジ７Ａ，７Ｂについて説明するに、下ヒンジ６Ａ，６Ｂは左右対称に構成されており、上ヒンジ７Ａ，７Ｂも左右対称に構成されている。しかも、下ヒンジ６Ａと上ヒンジ７Ａとは、一部の構成を除いて基本構成が同一になっている。そこで、下ヒンジ６Ａの構成についてまず詳細に説明し、上ヒンジ７Ａについては下ヒンジ６Ａとの相違点だけを説明する。また、下ヒンジ６Ｂ及び上ヒンジ７Ｂについてはその説明を省略する。   Next, the lower hinges 6A and 6B and the upper hinges 7A and 7B will be described. The lower hinges 6A and 6B are configured symmetrically, and the upper hinges 7A and 7B are also configured symmetrically. In addition, the basic structure of the lower hinge 6A and the upper hinge 7A is the same except for a part of the structure. Therefore, the configuration of the lower hinge 6A will be described in detail first, and only the differences from the lower hinge 6A will be described for the upper hinge 7A. Further, the description of the lower hinge 6B and the upper hinge 7B is omitted.

図６及び図１０〜図１２に示すように、下ヒンジ６Ａは、第１固定部材６１、第１ヒンジ軸６２、第１回動部材６３、第１可動部材６４及び第１コイルばね（第１付勢手段）６５を有している。   6 and 10 to 12, the lower hinge 6A includes a first fixed member 61, a first hinge shaft 62, a first rotating member 63, a first movable member 64, and a first coil spring (first coil). (Biasing means) 65.

第１固定部材６１は、円筒状をなしており、その一端部には底部６１ａが形成されている。この底部６１ａの中央部には、貫通孔６１ｂが形成されている。この貫通孔６１ｂには、第１ヒンジ軸６２が回動可能に挿通されている。第１ヒンジ軸６２の一端部には、頭部６２ａが形成されている。この頭部６２ａが第１固定部材６１の底部６１ａに突き当たることにより、第１固定部材６１が第１ヒンジ軸６２に対しその他端側から一端側へ向かう方向へ抜け止めされている。第１ヒンジ軸６２の他端部外周には、円筒状をなす第１回動部材６３が回動不能に嵌合されている。この結果、第１回動部材６３が第１固定部材６１に第１ヒンジ軸６２を介して回動可能に連結されている。第１回動部材６３は、第１ヒンジ軸６２の他端部を図１１において想像線で示すように加締めることにより、第１ヒンジ軸６２の一端側から他端側へ向かう方向へ抜け止めされている。   The first fixing member 61 has a cylindrical shape, and a bottom 61a is formed at one end thereof. A through hole 61b is formed at the center of the bottom 61a. The first hinge shaft 62 is rotatably inserted into the through hole 61b. A head 62 a is formed at one end of the first hinge shaft 62. When the head 62 a abuts against the bottom 61 a of the first fixing member 61, the first fixing member 61 is prevented from coming off from the other end side toward the one end side with respect to the first hinge shaft 62. A cylindrical first rotating member 63 is fitted on the outer periphery of the other end of the first hinge shaft 62 so as not to rotate. As a result, the first rotating member 63 is rotatably connected to the first fixing member 61 via the first hinge shaft 62. The first rotating member 63 prevents the first hinge shaft 62 from coming off in the direction from one end side to the other end side of the first hinge shaft 62 by caulking the other end portion of the first hinge shaft 62 as indicated by an imaginary line in FIG. Has been.

第１固定部材６１と第１回動部材６３との間に位置する第１ヒンジ軸６２の中間部には、第１可動部材６４が回動可能に、かつ第１ヒンジ軸６２の軸線方向へ移動可能に嵌合されている。この第１可動部材６４は、第１固定部材６１に回動不能に、かつ第１ヒンジ軸６２の軸線方向へ移動可能に連結されている。第１可動部材６４の第１回動部材６２との対向面には、一対の球体６６，６６がそれぞれの一部を第１回動部材６２側に突出させた状態で埋設されている。一対の球体６６，６６は、第１ヒンジ軸６２の軸線を中心とする円周上に周方向に１８０°離れて配置されている。球体６６に代えて、例えば球体６６の第１可動部材６４から突出した部分とほぼ同様な形状をなす突出部を第１可動部材６４に一体に形成してもよい。   A first movable member 64 is rotatable in an intermediate portion of the first hinge shaft 62 located between the first fixed member 61 and the first rotation member 63 and in the axial direction of the first hinge shaft 62. It is movably fitted. The first movable member 64 is connected to the first fixed member 61 so as not to rotate and to be movable in the axial direction of the first hinge shaft 62. A pair of spheres 66 and 66 are embedded in a surface of the first movable member 64 facing the first rotation member 62 in a state where a part of each of the spheres 66 and 66 protrudes toward the first rotation member 62. The pair of spheres 66 and 66 are disposed 180 degrees apart in the circumferential direction on the circumference centered on the axis of the first hinge shaft 62. Instead of the sphere 66, for example, a protruding portion having substantially the same shape as a portion protruding from the first movable member 64 of the sphere 66 may be formed integrally with the first movable member 64.

第１固定部材６１の底部と第１可動部材６４との間には、第１コイルばね６５が設けられている。第１コイルばね６５は、第１可動部材６４を第１回動部材６３側へ向かって付勢することにより、一対の球体６６を第１回動部材６３の第１可動部材６４との対向面に押圧接触させている。この結果、第１回動部材６３が第１ヒンジ軸６２の一端側から他端側へ向かう方向へ付勢され、第１ヒンジ軸６２の他端部に設けられた加締め部に突き当てられている。また、第１コイルばね６５は、第１固定部材６１の底部６１ａを第１ヒンジ軸６２の頭部６２ａに突き当てている。この結果、第１固定部材６１、第１回動部材６３、第１可動部材６４及び第１コイルばね６５が第１ヒンジ軸６２を介してユニット化されている。   A first coil spring 65 is provided between the bottom of the first fixed member 61 and the first movable member 64. The first coil spring 65 biases the first movable member 64 toward the first rotating member 63, thereby causing the pair of spheres 66 to face the first movable member 64 of the first rotating member 63. Is in press contact. As a result, the first rotating member 63 is biased in the direction from the one end side to the other end side of the first hinge shaft 62 and is abutted against the crimping portion provided at the other end portion of the first hinge shaft 62. ing. The first coil spring 65 abuts the bottom 61 a of the first fixing member 61 against the head 62 a of the first hinge shaft 62. As a result, the first fixed member 61, the first rotating member 63, the first movable member 64, and the first coil spring 65 are unitized via the first hinge shaft 62.

第１ヒンジ６Ａに関する上記構成は、第２ヒンジ７Ａについても同様であり、第２ヒンジ７Ａは、第１ヒンジ６Ａの第１固定部材６１、第１ヒンジ軸６２、第１回動部材６３、第１可動部材６４、第１コイルばね６５及び一対の球体６６，６６にそれぞれ対応する部材として、第２固定部材７１、第２ヒンジ軸７２、第２回動部材７３、第２可動部材７４、第２コイルばね（第２付勢手段）７５及び一対の球体７６，７６を有している。   The above-described configuration relating to the first hinge 6A is the same for the second hinge 7A. The second hinge 7A includes the first fixing member 61, the first hinge shaft 62, the first rotating member 63, and the first hinge 6A. As a member corresponding to each of the first movable member 64, the first coil spring 65, and the pair of spheres 66, 66, the second fixed member 71, the second hinge shaft 72, the second rotating member 73, the second movable member 74, the second A two-coil spring (second urging means) 75 and a pair of spheres 76 and 76 are provided.

第１ヒンジ６Ａ，６Ｂの第１固定部材６１は、第１収容孔５ａに回動不能に嵌合されている。したがって、第１固定部材６１は、ヒンジ本体５と一体に回動する。第１回動部材６３は、その略半分が第１収容孔５ａに回動可能に嵌合され、他の半分が送話ケース２の係合孔２ｇに回動不能に嵌合されている。したがって、送話ケース２とヒンジ本体５とは、実質的には第１回動部材６３を介して回動可能に連結されている。第１固定部材６１が第１収容孔５ａに嵌合されるとともに、第１回動部材６３が係合孔２ｇに嵌合された状態では、第１ヒンジ軸６２がその軸線を第１回動軸線Ｌ１と一致させている。したがって、送話ケース２とヒンジ本体５とは、第１回動軸線Ｌ１を中心として回動可能に連結されている。また、この実施の形態では、送話ケース２が回動しないものとされているので、第１回動部材６３が回動することがなく、ヒンジ本体５が送話ケース２に対して回動するときには、第１固定部材６１および第１可動部材６４が第１回動部材６３に対して回動する。   The first fixing member 61 of the first hinges 6A and 6B is fitted in the first accommodation hole 5a so as not to rotate. Accordingly, the first fixing member 61 rotates integrally with the hinge body 5. About half of the first rotating member 63 is fitted in the first receiving hole 5a so as to be rotatable, and the other half is fitted in the engaging hole 2g of the transmission case 2 so as not to be turned. Therefore, the transmission case 2 and the hinge body 5 are substantially pivotally connected via the first rotation member 63. In a state where the first fixing member 61 is fitted in the first accommodation hole 5a and the first rotation member 63 is fitted in the engagement hole 2g, the first hinge shaft 62 rotates the axis thereof for the first rotation. It is made to correspond with axis L1. Therefore, the transmission case 2 and the hinge body 5 are coupled so as to be rotatable about the first rotation axis L1. Further, in this embodiment, since the transmission case 2 is not rotated, the first rotation member 63 is not rotated, and the hinge body 5 is rotated with respect to the transmission case 2. When doing so, the first fixed member 61 and the first movable member 64 rotate with respect to the first rotating member 63.

第２ヒンジ７Ａ，７Ｂの第２固定部材７１は、第２収容孔５ｂに回動不能に嵌合されている。また、第２回動部材７３は、その略半分が第２収容孔５ｂに回動可能に嵌合され、他の半分が送話ケース２の係合孔３ｇに回動不能に嵌合されている。したがって、送話ケース２とヒンジ本体５とは、実質的には第２回動部材７３を介して回動可能に連結されている。第２固定部材７１が第２収容孔５ｂに嵌合されるとともに、第２回動部材７３が係合孔３ｇに嵌合された状態では、第２ヒンジ軸７２がその軸線を第２回動軸線Ｌ２と一致させている。したがって、受話ケース３とヒンジ本体５とは、第２回動軸線Ｌ２を中心として回動可能に連結されている。なお、この実施の形態では、受話ケース３がヒンジ本体５に対して第２回動軸線Ｌ２を中心として回動することはあっても、ヒンジ本体５が受話ケース３に対して第２回動軸線Ｌ２を中心として回動することがない。したがって、受話ケース３が回動するときには、第２固定部材７１がケース本体５に位置固定され、第２回動部材７３が第２固定部材７１に対して回動する。   The second fixing member 71 of the second hinges 7A and 7B is fitted in the second accommodation hole 5b so as not to rotate. Further, approximately half of the second rotating member 73 is rotatably fitted in the second receiving hole 5b, and the other half is non-rotatably fitted in the engaging hole 3g of the transmission case 2. Yes. Therefore, the transmission case 2 and the hinge body 5 are substantially pivotally connected via the second rotation member 73. In a state where the second fixing member 71 is fitted in the second accommodation hole 5b and the second rotation member 73 is fitted in the engagement hole 3g, the second hinge shaft 72 rotates the axis thereof for the second rotation. It is made to correspond with the axis line L2. Therefore, the reception case 3 and the hinge body 5 are coupled so as to be rotatable about the second rotation axis L2. In this embodiment, even if the reception case 3 rotates about the second rotation axis L <b> 2 with respect to the hinge body 5, the hinge body 5 rotates second with respect to the reception case 3. There is no rotation about the axis L2. Therefore, when the receiving case 3 rotates, the second fixing member 71 is fixed to the case body 5 and the second rotating member 73 rotates with respect to the second fixing member 71.

送話ケース３を図１に示す折畳位置から図２に示す中間位置を経て図３に示す通話位置まで回動させた後、通話位置から中間位置を経て折畳位置まで戻すときには、受話ケース３とヒンジ本体５とが所定の順序で回動する。すなわち、受話ケース３が折畳位置から中間位置まで回動する際には、ヒンジ本体５が図７に示す位置に停止した状態を維持する。このときのヒンジ本体５の位置が第１初期位置である。その一方、受話ケース３がヒンジ本体５に対し第２回動軸線Ｌ１を中心として図７に示す第２初期位置から図８に示す第２回動位置まで所定角度（この実施の形態では１００°）だけ回動する。これにより、受話ケース３が折畳位置から中間位置まで回動する。したがって、ヒンジ本体５が第１初期位置に位置しているときには、受話ケース３の折畳位置と第２初期位置とが同一位置になっており、中間位置と第２回動位置とが同一位置になっている。受話ケース３を中間位置から通話位置に向かってさらに回動させようとすると、受話ケース３がヒンジ本体５に対して停止状態を維持する一方、ヒンジ本体５が第１回動軸線Ｌ１を中心として第１初期位置から第１回動位置側へ向かって回動し始める。その結果、受話ケース３が中間位置から通話位置側へ回動する。そして、ヒンジ本体５が第１初期位置から所定角度（この実施の形態では６０°）だけ回動して図９に示す第１回動位置に達すると、ヒンジ本体５が停止する。このとき、受話ケース３が通話位置に達している。   When the transmission case 3 is rotated from the folding position shown in FIG. 1 to the call position shown in FIG. 3 through the intermediate position shown in FIG. 2, the case is returned from the call position to the folding position via the intermediate position. 3 and the hinge body 5 rotate in a predetermined order. That is, when the receiving case 3 is rotated from the folding position to the intermediate position, the hinge body 5 is maintained in a stopped state at the position shown in FIG. The position of the hinge body 5 at this time is the first initial position. On the other hand, the receiving case 3 has a predetermined angle (100 ° in this embodiment) from the second initial position shown in FIG. 7 to the second rotational position shown in FIG. ). Thereby, the reception case 3 rotates from the folding position to the intermediate position. Therefore, when the hinge body 5 is located at the first initial position, the folding position of the reception case 3 and the second initial position are the same position, and the intermediate position and the second rotation position are the same position. It has become. When the receiving case 3 is further rotated from the intermediate position toward the talking position, the receiving case 3 maintains a stopped state with respect to the hinge body 5, while the hinge body 5 is centered on the first rotation axis L1. It starts to turn from the first initial position toward the first turning position. As a result, the reception case 3 rotates from the intermediate position to the call position side. Then, when the hinge main body 5 rotates by a predetermined angle (60 ° in this embodiment) from the first initial position and reaches the first rotation position shown in FIG. 9, the hinge main body 5 stops. At this time, the reception case 3 has reached the call position.

受話ケース３を通話位置から中間位置まで回動させる場合には、当初、受話ケース３がヒンジ本体５に対し第２回動位置において停止状態を維持し、ヒンジ本体５が第１回動軸線Ｌ１を中心として第１回動位置から第１初期位置まで回動する。これにより、受話ケース３が通話位置から中間位置まで回動することになる。受話ケース３を中間位置から折畳位置まで回動させる際には、ヒンジ本体５が第１初期位置において停止状態を維持する一方、受話ケース３がヒンジ本体５に対し第２回動軸線Ｌ２を中心として第２回動位置から第２初期位置まで回動する。これにより、受話ケース３が中間位置から折畳位置まで回動する。   When the receiving case 3 is rotated from the talking position to the intermediate position, the receiving case 3 initially maintains a stopped state at the second rotating position with respect to the hinge main body 5, and the hinge main body 5 is in the first rotating axis L1. Is rotated from the first rotation position to the first initial position. As a result, the reception case 3 is rotated from the call position to the intermediate position. When the reception case 3 is rotated from the intermediate position to the folding position, the hinge body 5 maintains the stopped state at the first initial position, while the reception case 3 moves the second rotation axis L <b> 2 with respect to the hinge body 5. The center pivots from the second pivot position to the second initial position. Thereby, the reception case 3 rotates from the intermediate position to the folding position.

受話ケース３及びヒンジ本体５を上記の順序で回動させるために、図１４に示すように、第１回動部材６３の第１可動部材６４との対向面には、第１係合凹部６３Ａ，６３Ｂが二対形成され、第２回動部材７３の第２可動部材７４との対向面には、第２係合凹部７３Ａ，７３Ｂが二対形成されている。二対の第１係合凹部６３Ａ，６３Ｂは、一対の球体６６，６６が配置された円周と同一の円周上に配置されている。一方の一対の第１係合凹部６３Ａ，６３Ｂと他方の一対の第１係合凹部６３Ａ，６３Ｂとは、第１回動軸線Ｌ１を中心として対称に配置されている。つまり、周方向に１８０°離れて配置されている。第１係合凹部６３Ａ，６３Ｂは、周方向に所定角度（この実施の形態ではほぼ６０°）だけ離れて配置されている。一方、二対の第２係合凹部７３Ａ，７３Ｂは、一対の球体７６，７６が配置された円周と同一の円周上に配置されている。一方の一対の第２係合凹部７３Ａ，７３Ｂと他方の一対の第２係合凹部７３Ａ，７３Ｂとは、第２回動軸線Ｌ２を中心として対称に配置されている。つまり、周方向に１８０°離れて配置されている。第２係合凹部７３Ａ，７３Ｂは、周方向に所定の角度（この実施の形態ではほぼ１００°）だけ離れて配置されている。   In order to rotate the receiving case 3 and the hinge main body 5 in the above order, as shown in FIG. 14, the first engaging recess 63A is formed on the surface of the first rotating member 63 facing the first movable member 64. 63B and two pairs of second engaging recesses 73A and 73B are formed on the surface of the second rotating member 73 facing the second movable member 74. The two pairs of first engaging recesses 63A and 63B are arranged on the same circumference as the circumference where the pair of spheres 66 and 66 are arranged. One pair of first engaging recesses 63A and 63B and the other pair of first engaging recesses 63A and 63B are disposed symmetrically about the first rotation axis L1. That is, they are arranged 180 ° apart in the circumferential direction. The first engaging recesses 63A and 63B are disposed apart from each other by a predetermined angle (approximately 60 ° in this embodiment) in the circumferential direction. On the other hand, the two pairs of second engaging recesses 73A and 73B are arranged on the same circumference as the circumference where the pair of spheres 76 and 76 are arranged. One pair of second engagement recesses 73A and 73B and the other pair of second engagement recesses 73A and 73B are disposed symmetrically about the second rotation axis L2. That is, they are arranged 180 ° apart in the circumferential direction. The second engaging recesses 73A and 73B are arranged apart from each other by a predetermined angle (approximately 100 ° in this embodiment) in the circumferential direction.

図１５及び図１８に示すように、第１係合凹部６３Ａは、その中央部から第１回動軸線Ｌ１を中心とする周方向における両端縁へ向かって上り勾配をなす傾斜面６３ａ，６３ｂを有している。図１５に示すように、傾斜面６３ａ，６３ｂは、ヒンジ本体５が第１初期位置に位置しているときに、第１コイルばね６５によって付勢された球体６６が同時に押圧接触するように配置されている。これにより、ヒンジ本体５に力が作用しない限り、ヒンジ本体５が第１初期位置に維持されるようになっている。   As shown in FIGS. 15 and 18, the first engaging recess 63 </ b> A has inclined surfaces 63 a and 63 b that form an upward gradient from the central portion toward both end edges in the circumferential direction around the first rotation axis L <b> 1. Have. As shown in FIG. 15, the inclined surfaces 63a and 63b are arranged so that the spheres 66 urged by the first coil springs 65 are pressed and contacted simultaneously when the hinge body 5 is located at the first initial position. Has been. Thereby, unless a force acts on the hinge body 5, the hinge body 5 is maintained at the first initial position.

第１係合凹部６３Ａの傾斜面６３ａは、第１コイルばね６５の付勢力を回動付勢力に変換する。この回動付勢力は、ヒンジ本体５が第１初期位置から第１回動位置側へ回動しようとし、その結果球体６６が第１固定部材６１及び第１可動部材６４を介して図１５の矢印Ｘ方向（第１回動軸線Ｌ１を中心とする周方向）へ移動しようとするときに、その移動を阻止し、それによってヒンジ本体５が第１初期位置から第１回動位置側へ回動するのを阻止しようとする回動阻止力として作用する。したがって、球体６６と傾斜面６３ａとによって第１初期位置側変換手段８Ａが構成され、第１初期位置側変換手段８Ａと第１コイルばね６５とによって第１初期位置側回動阻止手段９Ａが構成されている。   The inclined surface 63a of the first engaging recess 63A converts the urging force of the first coil spring 65 into a rotating urging force. This turning biasing force causes the hinge body 5 to turn from the first initial position to the first turning position, and as a result, the sphere 66 moves through the first fixed member 61 and the first movable member 64 in FIG. When moving in the direction of the arrow X (the circumferential direction centered on the first rotation axis L1), the movement is prevented, whereby the hinge body 5 rotates from the first initial position to the first rotation position. Acts as a rotation-preventing force that tries to prevent movement. Therefore, the spherical body 66 and the inclined surface 63a constitute the first initial position side converting means 8A, and the first initial position side converting means 8A and the first coil spring 65 constitute the first initial position side rotation preventing means 9A. Has been.

第１係合凹部６３Ａの傾斜面６３ｂは、第１コイルばね６５の付勢力を回動付勢力に変換する。この回動付勢力は、ヒンジ本体５が第１回動軸線Ｌ１を中心として第１回動位置側から第１初期位置側へ回動する場合において、第１初期位置を越えて回動しようとするときに、球体６６が図１５の矢印Ｙ方向へ移動するのを阻止し、それによってヒンジ本体５を第１初期位置に停止させる。したがって、第１コイルばね６５、球体６６及び傾斜面６３ｂによって第１初期位置側停止手段１０Ａが構成されている。   The inclined surface 63b of the first engaging recess 63A converts the urging force of the first coil spring 65 into a rotating urging force. This rotation biasing force tends to rotate beyond the first initial position when the hinge body 5 rotates from the first rotation position side to the first initial position side about the first rotation axis L1. When this is done, the sphere 66 is prevented from moving in the direction of arrow Y in FIG. 15, thereby stopping the hinge body 5 in the first initial position. Accordingly, the first initial position side stopping means 10A is constituted by the first coil spring 65, the spherical body 66, and the inclined surface 63b.

図１５及び図１８に示すように、係合凹部６３Ｂは、その中央部から第１回動軸線Ｌ１を中心とする周方向における両端縁へ向かって上り勾配をなす傾斜面６３ｃ，６３ｄを有している。図１８に示すように、傾斜面６３ｃ，６３ｄは、ヒンジ本体５が第１回動位置に位置しているときに、第１コイルばね６５によって付勢された球体６６が同時に押圧接触するように配置されている。これにより、ヒンジ本体５に力が作用しない限り、ヒンジ本体５が第１回動位置に維持されるようになっている。   As shown in FIGS. 15 and 18, the engaging recess 63B has inclined surfaces 63c and 63d that form an upward gradient from the central portion toward both end edges in the circumferential direction around the first rotation axis L1. ing. As shown in FIG. 18, the inclined surfaces 63 c and 63 d are arranged so that the spherical body 66 urged by the first coil spring 65 is simultaneously pressed and contacted when the hinge body 5 is located at the first rotation position. Has been placed. Thereby, as long as force does not act on the hinge main body 5, the hinge main body 5 is maintained in the 1st rotation position.

第１係合凹部６３Ｂの傾斜面６３ｃは、第１コイルばね６５の付勢力を回動付勢力に変換する。この回動付勢力は、ヒンジ本体５が第１回動位置から第１初期位置側へ回動しようとし、その結果球体６６が図１８の矢印Ｙ方向へ移動しようとするときに、その移動を阻止し、それによってヒンジ本体５が第１回動位置から第１初期位置側へ回動するのを阻止しようとする回動阻止力として作用する。したがって、球体６６と傾斜面６３ｃとによって第１回動位置側変換手段８Ｂが構成され、第１回動位置側変換手段８Ｂと第１コイルばね６５とによって第１回動位置側回動阻止手段９Ｂが構成されている。   The inclined surface 63c of the first engaging recess 63B converts the urging force of the first coil spring 65 into a rotating urging force. This turning biasing force is caused to move when the hinge body 5 tries to turn from the first turning position to the first initial position, and as a result, the sphere 66 tries to move in the direction of the arrow Y in FIG. This prevents the hinge body 5 from rotating from the first rotation position to the first initial position, thereby acting as a rotation prevention force. Therefore, the spherical body 66 and the inclined surface 63c constitute the first rotation position side conversion means 8B, and the first rotation position side conversion means 8B and the first coil spring 65 constitute the first rotation position side rotation prevention means. 9B is configured.

第１係合凹部６３Ｂの傾斜面６３ｄは、第１コイルばね６５の付勢力を回動付勢力に変換する。この回動付勢力は、ヒンジ本体５が第１回動軸線Ｌ１を中心として第１初期位置側から第１回動位置側へ回動する場合において、第１回動位置を越えて回動しようとするときに、球体６６が図５の矢印Ｘ方向へ移動するのを阻止し、それによってヒンジ本体５を第１回動位置に停止させる。第１コイルばね６５、球体６６及び傾斜面６３ｄによって第１回動位置側停止手段１０Ｂが構成されている。   The inclined surface 63d of the first engaging recess 63B converts the urging force of the first coil spring 65 into a rotating urging force. This rotational biasing force is intended to rotate beyond the first rotational position when the hinge body 5 rotates from the first initial position side to the first rotational position side about the first rotational axis L1. , The sphere 66 is prevented from moving in the direction of the arrow X in FIG. 5, thereby stopping the hinge body 5 at the first rotation position. The first coil spring 65, the spherical body 66, and the inclined surface 63d constitute the first rotation position side stop means 10B.

図１６及び図１７に示すように、第２係合凹部７３Ａは、その中央部から第２回動軸線Ｌ２を中心とする周方向における両端縁に向かって上り勾配をなす傾斜面７３ａ，７３ｂを有している。図１６に示すように、傾斜面７３ａ，７３ｂは、受話ケース３が第２初期位置に位置しているときに、第２コイルばね７５によって付勢された球体７６が同時に押圧接触するように配置されている。これにより、受話部３に力が作用しない限り、受話部３が第２初期位置に維持されるようになっている。   As shown in FIGS. 16 and 17, the second engaging recess 73A has inclined surfaces 73a and 73b that form an upward slope from the central portion toward both end edges in the circumferential direction around the second rotation axis L2. Have. As shown in FIG. 16, the inclined surfaces 73 a and 73 b are arranged so that the spheres 76 urged by the second coil springs 75 are pressed and contacted simultaneously when the receiving case 3 is located at the second initial position. Has been. Thereby, unless a force acts on the receiver 3, the receiver 3 is maintained at the second initial position.

第２係合凹部７３の傾斜面７３ａは、第２コイルばね７５の付勢力を回動付勢力に変換する。この回動付勢力は、受話ケース３が第２回動軸線Ｌ２を中心として第２初期位置から第２回動位置側へ回動しようとし、それに伴って第２回動部材７３が図１６のＸ方向へ回動しようとするときに、第２回動部材の７３回動を阻止し、それによって受話ケース３が第２初期位置から第２回動位置側へ回動するのを阻止しようとする回動阻止力として作用する。したがって、球体７６と傾斜面７３ａとによって第２初期位置側変換手段８Ｃが構成され、第２初期位置側変換手段８Ｃと第２コイルばね７５とによって第２初期位置側回動阻止手段９Ｃが構成されている。   The inclined surface 73a of the second engaging recess 73 converts the urging force of the second coil spring 75 into a rotating urging force. The turning urging force causes the receiving case 3 to turn from the second initial position to the second turning position side about the second turning axis L2, and accordingly, the second turning member 73 in FIG. When trying to turn in the X direction, the second turning member is prevented from turning 73, thereby preventing the receiving case 3 from turning from the second initial position to the second turning position. It acts as a turning prevention force. Accordingly, the spherical body 76 and the inclined surface 73a constitute the second initial position side converting means 8C, and the second initial position side converting means 8C and the second coil spring 75 constitute the second initial position side rotation preventing means 9C. Has been.

第２係合凹部７３Ａの傾斜面７３ｂは、第２コイルばね７５の付勢力を回動付勢力に変換する。この回動付勢力は、受話ケース３が第２回動位置側から第２初期位置側へ向かう方向へ回動する場合において第２初期位置を越えて回動しようとするときに、受話ケース３の回動に伴って第２回動部材７３が図１６の矢印Ｙ方向へ回動するのを阻止し、それによって受話ケース３を第２初期位置に停止させる。したがって、第２コイルばね７５、傾斜面７３ｂ及び球体７６によって第２初期位置側停止手段１０Ｃが構成されている。   The inclined surface 73b of the second engaging recess 73A converts the urging force of the second coil spring 75 into a rotating urging force. The turning urging force is applied to the receiving case 3 when the receiving case 3 tries to turn beyond the second initial position when the receiving case 3 turns in the direction from the second turning position to the second initial position. With this rotation, the second rotation member 73 is prevented from rotating in the direction of arrow Y in FIG. 16, thereby stopping the reception case 3 at the second initial position. Accordingly, the second coil spring 75, the inclined surface 73b, and the spherical body 76 constitute the second initial position side stop means 10C.

図１６及び図１７に示すように、第２係合凹部７３Ｂは、その中央部から第２回動軸線Ｌ２を中心とする周方向における両端縁に向かって上り勾配をなす傾斜面７３ｃ，７３ｄを有している。図１７に示すように、傾斜面７３ｃ，７３ｄは、受話ケース３が第２回動位置に位置しているときに、第２コイルばね７５によって付勢された球体７６が同時に押圧接触するように配置されている。これにより、受話部３に力が作用しない限り、受話部３が第２回動位置に維持されるようになっている。   As shown in FIGS. 16 and 17, the second engaging recess 73 </ b> B has inclined surfaces 73 c and 73 d that form an upward gradient from the central portion toward both end edges in the circumferential direction around the second rotation axis L <b> 2. Have. As shown in FIG. 17, the inclined surfaces 73 c and 73 d are arranged so that the spherical body 76 urged by the second coil spring 75 is pressed and contacted at the same time when the receiving case 3 is located at the second rotation position. Has been placed. Thereby, unless a force acts on the receiver 3, the receiver 3 is maintained at the second rotation position.

第２係合凹部７３Ｂの傾斜面７３ｃは、第２コイルばね７５の付勢力を回動付勢力に変換する。この回動付勢力は、受話ケース３が第２回動軸線Ｌ２を中心として第２回動位置から第２初期位置側へ向かう方向へ回動しようとし、それに伴って第２回動部材７３が図１７の矢印Ｙ方向へ回動しようとするときに、その回動を阻止しようとし、それによって受話ケース３が第２回動位置から第２初期位置側へ回動しようとするのを阻止する回動阻止力として作用する。したがって、球体７６と傾斜面７３ｃとによって第２回動位置側変換手段８Ｄが構成され、第２初期位置側変換手段８Ｄと第２コイルばね７５とによって第２回動位置側回動阻止手段９Ｄが構成されている。   The inclined surface 73c of the second engagement recess 73B converts the urging force of the second coil spring 75 into a rotating urging force. The turning urging force causes the receiving case 3 to turn in the direction from the second turning position toward the second initial position with the second turning axis L2 as the center. When attempting to rotate in the direction of arrow Y in FIG. 17, the rotation is prevented, thereby preventing the reception case 3 from rotating from the second rotation position to the second initial position. Acts as a rotation prevention force. Therefore, the spherical body 76 and the inclined surface 73c constitute the second rotation position side conversion means 8D, and the second initial position side conversion means 8D and the second coil spring 75 constitute the second rotation position side rotation prevention means 9D. Is configured.

第２係合凹部７３Ｂの傾斜面７３ｄは、第２コイルばね７５の付勢力を回動付勢力に変換する。この回動付勢力は、受話ケース３が第２初期位置側から第２回動位置側へ向かう方向へ回動する場合において第２回動位置を越えて回動しようとするときに、それに伴って第２回動部材７３が図１７の矢印Ｘ方向へ回動するのを阻止し、それによって受話ケース３が第２回動位置を越えて回動するのを阻止して第２回動位置に停止させる。したがって、第２コイルばね７５、傾斜面７３ｄ及び球体７６によって第２回動位置側停止手段１０Ｄが構成されている。   The inclined surface 73d of the second engaging recess 73B converts the urging force of the second coil spring 75 into a rotating urging force. This turning biasing force is generated when the receiving case 3 is turned in the direction from the second initial position side toward the second turning position side when it tries to turn beyond the second turning position. Thus, the second rotation member 73 is prevented from rotating in the direction of the arrow X in FIG. 17, thereby preventing the receiving case 3 from rotating beyond the second rotation position and the second rotation position. To stop. Therefore, the second rotating position side stop means 10 </ b> D is configured by the second coil spring 75, the inclined surface 73 d and the sphere 76.

次に、上記各手段８Ａ〜８Ｄ及び９Ａ〜９Ｄの回動阻止力及び停止力を比較するに、いま、受話ケース３が折畳位置に位置しているものとする。つまり、ヒンジ本体５が第１初期位置に位置し、受話ケース３が第２初期位置に位置しているものとする。受話ケース３を折畳位置から中間位置側へ回動させようとすると、第１初期位置側回動阻止手段９Ａがヒンジ本体５の第１初期位置から第１回動位置側への回動を阻止しようとし、第２初期位置側回動阻止手段９Ｃが受話ケース３の第２初期位置から第２回動位置側への回動を阻止しようとする。第１初期位置側回動阻止手段９Ａの一部を構成する第１係合凹部６３Ａの傾斜面６３ａの傾斜角度をα１（図１５参照）とし、第２初期位置側回動阻止手段９Ｃの一部を構成する第２係合凹部７３Ａの傾斜面７３ａの傾斜角度をβ１（図１６参照）とすると、
α１＞β１
に設定されている。したがって、第１初期位置側回動阻止手段９Ａの回動阻止力と第２初期位置側回動阻止手段９Ｃの回動阻止力とを比較すると、前者が後者より大きくなっている。よって、折畳位置に位置している受話ケース３を中間位置側へ回動させようとすると、ヒンジ本体５がその位置を第１初期位置に維持する一方、受話ケース３が第２初期位置側回動阻止手段９Ｃの回動付勢力に抗して第２初期位置から第２回動位置側へ回動する。 Next, in order to compare the rotation preventing force and the stopping force of each of the means 8A to 8D and 9A to 9D, it is assumed that the receiving case 3 is now in the folding position. That is, it is assumed that the hinge body 5 is located at the first initial position and the receiving case 3 is located at the second initial position. When the receiving case 3 is to be rotated from the folding position to the intermediate position side, the first initial position side rotation preventing means 9A rotates the hinge body 5 from the first initial position to the first rotation position side. The second initial position side rotation prevention means 9C tries to prevent the rotation of the reception case 3 from the second initial position to the second rotation position side. The inclination angle of the inclined surface 63a of the first engaging recess 63A constituting a part of the first initial position side rotation preventing means 9A is α1 (see FIG. 15), and one of the second initial position side rotation preventing means 9C. When the inclination angle of the inclined surface 73a of the second engaging recess 73A constituting the part is β1 (see FIG. 16),
α1> β1
Is set to Therefore, when comparing the rotation prevention force of the first initial position side rotation prevention means 9A and the rotation prevention force of the second initial position side rotation prevention means 9C, the former is larger than the latter. Therefore, when the reception case 3 located at the folding position is to be rotated to the intermediate position side, the hinge body 5 maintains the position at the first initial position, while the reception case 3 is at the second initial position side. It turns from the second initial position to the second turning position side against the turning biasing force of the turning prevention means 9C.

受話ケース３が中間位置に位置している場合、つまりヒンジ本体５が第１初期位置に位置し、かつ受話ケース３が第２回動位置に位置している場合において、受話ケース３を中間位置から通話位置側へ回動させるときには、第１初期位置側回動阻止手段９Ａがヒンジ本体５の第１初期位置から第１回動位置側への回動を阻止しようとし、第２回動位置停止手段１０Ｄが受話ケース３の第２回動位置を越える回動を阻止しようとする。第２回動位置停止手段１０Ｄの一部を構成する第２係合凹部７３Ｂの傾斜面７３ｄの傾斜角度をβ２（図１６参照）とすると、
α１＜β２
に設定されている。したがって、第１初期位置側回動阻止手段９Ａの回動阻止力と第２回動位置側停止手段１０Ｄの回動阻止力とを比較すると、後者が前者より大きくなっている。よって、中間位置に位置している受話ケース３を通話位置側へ回動させると、受話ケース３がヒンジ本体５に対し第２回動位置を越えて回動するのを阻止され、第２回動位置に停止させられた状態を維持する。一方、ヒンジ本体５が第１初期位置側回動阻止手段９Ａの回動阻止力に抗して第１初期位置から第１回動位置側へ回動する。 When the reception case 3 is positioned at the intermediate position, that is, when the hinge body 5 is positioned at the first initial position and the reception case 3 is positioned at the second rotation position, the reception case 3 is positioned at the intermediate position. The first initial position side rotation preventing means 9A tries to prevent the hinge body 5 from rotating from the first initial position to the first rotation position side when the second rotation position is turned to the talking position side. The stopping means 10D tries to prevent the receiving case 3 from turning beyond the second turning position. When the inclination angle of the inclined surface 73d of the second engaging recess 73B constituting a part of the second rotation position stopping means 10D is β2 (see FIG. 16),
α1 <β2
Is set to Therefore, when comparing the rotation prevention force of the first initial position side rotation prevention means 9A and the rotation prevention force of the second rotation position side stop means 10D, the latter is larger than the former. Therefore, when the reception case 3 located at the intermediate position is rotated to the call position side, the reception case 3 is prevented from rotating beyond the second rotation position with respect to the hinge body 5, and the second time. The state stopped at the moving position is maintained. On the other hand, the hinge body 5 rotates from the first initial position to the first rotation position side against the rotation blocking force of the first initial position side rotation blocking means 9A.

受話ケース３が通話位置に位置している場合には、受話ケース３がヒンジ本体５に対して第２回動位置に位置し、ヒンジ本体５が第１回動位置に位置している。その状態において受話ケース３を通話位置から中間位置側へ回動させようとすると、第１回動位置側回動阻止手段９Ｂが球体６６の図１８における矢印Ｙ方向への移動を阻止し、ひいてはヒンジ本体５の第１回動位置から第１初期位置側への回動を阻止しようとする。これと同時に、第２回動位置側阻止手段９Ｄが第２回動部材７３の図１７における矢印Ｘ方向への回動を阻止し、ひいては受話ケース３の第２回動位置から第２初期位置側への回動を阻止しようとする。ここで、第１回動位置側回動阻止手段９Ｂの一部を構成する第１係合凹部６３Ｂの傾斜面６３ｃの傾斜角度をα２（図１５参照）とし、第２回動位置側回動阻止手段９Ｄの一部を構成する第２係合凹部７３Ｂの傾斜面７３ｃの傾斜角度をβ３（図１６参照）とすると、
α２＜β３
に設定されている。したがって、第１回動位置側阻止手段９ｂの回動阻止力と第２回動位置側回動阻止手段９ｄの回動阻止力とを比較すると、後者が前者より大きくなっている。よって、通話位置に位置している受話ケース３を中間位置側へ回動させると、受話ケース３はヒンジ本体５に対し第２回動位置において停止状態を維持し、ヒンジ本体５が第１回動位置から第１初期位置側へ回動する。 When the reception case 3 is located at the call position, the reception case 3 is located at the second rotation position with respect to the hinge body 5, and the hinge body 5 is located at the first rotation position. If the receiving case 3 is to be rotated from the talking position to the intermediate position in this state, the first rotation position side rotation blocking means 9B blocks the movement of the sphere 66 in the direction of arrow Y in FIG. An attempt is made to prevent the hinge body 5 from rotating from the first rotation position to the first initial position. At the same time, the second rotation position side blocking means 9D blocks the rotation of the second rotation member 73 in the direction of the arrow X in FIG. 17, and as a result, from the second rotation position of the receiving case 3 to the second initial position. Trying to prevent sideways rotation. Here, the inclination angle of the inclined surface 63c of the first engaging recess 63B constituting a part of the first rotation position side rotation preventing means 9B is α2 (see FIG. 15), and the second rotation position side rotation is performed. When the inclination angle of the inclined surface 73c of the second engaging recess 73B constituting a part of the blocking means 9D is β3 (see FIG. 16),
α2 <β3
Is set to Therefore, when the rotation prevention force of the first rotation position side blocking means 9b and the rotation prevention force of the second rotation position side rotation prevention means 9d are compared, the latter is larger than the former. Therefore, when the reception case 3 located at the call position is rotated to the intermediate position side, the reception case 3 maintains a stopped state at the second rotation position with respect to the hinge body 5, and the hinge body 5 is moved in the first time. It rotates from the moving position to the first initial position side.

受話ケース３が中間位置に位置しているときには、ヒンジ本体５が第１初期位置に位置し、受話ケース３がヒンジ本体５に対して第２回動位置に位置している。この状態におて、受話ケース３を中間位置から折畳位置側へ回動させようとすると、第１初期位置側停止手段１０Ａが球体６６の図１５における矢印Ｙ方向への移動を阻止し、ヒンジ本体５の第１初期位置を越える回動を阻止しようとする。これと同時に、第２回動位置側回動阻止手段９Ｄが第２回動部材７３の図１７における矢印Ｙ方向への回動を阻止し、受話ケース３の第２回動位置から第２初期位置側への回動を阻止しようとする。ここで、第１初期位置側停止手段１０Ａの一部を構成する第１係合凹部６３Ａの傾斜面６３ｂの傾斜角度をα３（図１５参照）とすると、
α３＞β３
に設定されている。したがって、第１初期位置側停止手段１０Ａの停止力と第２回動位置側回動阻止手段９Ｄの回動阻止力とを比較すると、前者が後者より大きくなっている。よって、中間位置に位置している受話ケース３を折畳位置側へ回動させると、ヒンジ本体５が第１初期位置において停止状態を維持する一方、受話ケース３が第２回動位置から第２初期位置側へ回動する。なお、角度α３は、角度β２と同一に設定されている。 When the reception case 3 is located at the intermediate position, the hinge body 5 is located at the first initial position, and the reception case 3 is located at the second rotation position with respect to the hinge body 5. In this state, if the reception case 3 is to be rotated from the intermediate position to the folding position side, the first initial position side stop means 10A prevents the movement of the sphere 66 in the arrow Y direction in FIG. An attempt is made to prevent the hinge body 5 from rotating beyond the first initial position. At the same time, the second rotation position side rotation blocking means 9D blocks the rotation of the second rotation member 73 in the arrow Y direction in FIG. Attempts to prevent rotation to the position side. Here, when the inclination angle of the inclined surface 63b of the first engaging recess 63A constituting a part of the first initial position side stop means 10A is α3 (see FIG. 15),
α3> β3
Is set to Therefore, when comparing the stopping force of the first initial position side stopping means 10A and the rotation stopping force of the second turning position side rotation preventing means 9D, the former is larger than the latter. Therefore, when the reception case 3 located at the intermediate position is rotated to the folding position side, the hinge body 5 remains stopped at the first initial position, while the reception case 3 is moved from the second rotation position to the second rotation position. 2 Turn to the initial position. The angle α3 is set to be the same as the angle β2.

なお、第１回動位置側停止手段１０Ｂの一部を構成する第１係合凹部６３Ｂの傾斜面６３ｄの傾斜角度をα４（図１５参照）とし、第２初期位置側停止手段１０Ｃの一部を構成する第２係合凹部７３Ａの傾斜面７３ｂの傾斜角度をβ４（図１６参照）とすると、
α４＝β４＝α３（＝β２）
に設定されている。 Note that the inclination angle of the inclined surface 63d of the first engaging recess 63B that constitutes a part of the first rotation position side stop means 10B is α4 (see FIG. 15), and a part of the second initial position side stop means 10C. When the inclination angle of the inclined surface 73b of the second engaging recess 73A that constitutes is β4 (see FIG. 16),
α4 = β4 = α3 (= β2)

上記構成の携帯電話機１において、いま受話ケース３が折畳位置に位置しているものとする。この状態においては、図１５に示すように、球体６６が第１係合凹部６３Ａの傾斜面６３ａ，６３ｂに接触し、図１６に示すように、球体７６が第２係合凹部７３Ａの傾斜面７３ａ，７３ｂに接触している。受話ケース３を通話位置側へ向かって回動させると、ヒンジ本体５は第１初期位置において停止状態を維持し、受話ケース３が第２初期位置側回動付勢手段９Ｃの回動付勢力に抗して第２初期位置から第２回動位置側へ回動する。受話ケース３が第２初期位置から所定角度（例えば１０°）だけ回動すると、球体７６が第２係合凹部７３Ａから抜け出る。すると、球体７６が第２回動部材７３の第２可動部材７４との対向面に接触する。この対向面は、第２回動軸線Ｌ２と直交する平面になっている。したがって、当該対向面と球体７６との間には、コイルばね７５の付勢力に応じた摩擦抵抗が発生する。この摩擦抵抗により、受話ケース３が第２係合凹部７３Ａを抜け出てから第２係合凹部７３Ｂに入り込むまでのうち、両端の所定角度を除いた所定の範囲においては、受話ケース３が任意の位置で停止させられる。   In the mobile phone 1 having the above configuration, it is assumed that the receiving case 3 is now in the folded position. In this state, as shown in FIG. 15, the sphere 66 contacts the inclined surfaces 63a and 63b of the first engaging recess 63A, and as shown in FIG. 16, the sphere 76 becomes the inclined surface of the second engaging recess 73A. 73a and 73b are in contact. When the reception case 3 is rotated toward the call position side, the hinge body 5 maintains the stopped state at the first initial position, and the reception case 3 is rotated by the second initial position side rotation urging means 9C. Against this, it rotates from the 2nd initial position to the 2nd rotation position side. When the reception case 3 is rotated by a predetermined angle (for example, 10 °) from the second initial position, the sphere 76 comes out of the second engagement recess 73A. Then, the spherical body 76 comes into contact with the surface of the second rotating member 73 facing the second movable member 74. This opposing surface is a plane orthogonal to the second rotation axis L2. Therefore, a frictional resistance corresponding to the biasing force of the coil spring 75 is generated between the facing surface and the sphere 76. Due to this frictional resistance, the receiving case 3 is in an arbitrary range within a predetermined range excluding a predetermined angle at both ends until the receiving case 3 comes out of the second engaging recess 73A and enters the second engaging recess 73B. Stopped at position.

受話ケース３が中間位置から所定角度（例えば１０°）だけ手前の位置に達すると、球体７６が第２係合凹部７３Ｂの傾斜面７３ｃに接触するようになる。すると、第２回動位置側回動阻止手段９Ｄの付勢力によって受話ケース３が中間位置（第２回動位置）まで自動的に回動させられる。受話ケース３が中間位置に達すると、球体７６が傾斜面７３ｄに突き当たることによって停止し、受話ケース３が中間位置に停止する。このときには、図１５に示すように、球体６６が第１係合凹部６３Ａの傾斜面６３ａ，６３ｂに接触するとともに、図１７に示すように、球体７６が第２係合凹部７３Ｂの傾斜面７３ｃ、７３ｄに接触している。   When the reception case 3 reaches a position in front of the intermediate position by a predetermined angle (for example, 10 °), the sphere 76 comes into contact with the inclined surface 73c of the second engagement recess 73B. Then, the receiving case 3 is automatically rotated to the intermediate position (second rotation position) by the urging force of the second rotation position side rotation prevention means 9D. When the reception case 3 reaches the intermediate position, the sphere 76 stops by hitting the inclined surface 73d, and the reception case 3 stops at the intermediate position. At this time, as shown in FIG. 15, the sphere 66 contacts the inclined surfaces 63a and 63b of the first engaging recess 63A, and as shown in FIG. 17, the sphere 76 becomes the inclined surface 73c of the second engaging recess 73B. , 73d.

受話ケース３を中間位置から通話位置側へ回動させる場合には、受話ケース３が第２回動位置に停止した状態を維持し、ヒンジ本体５が第１初期位置側回動阻止手段９Ａの付勢力に抗して第１初期位置から第１回動位置側へ回動する。ヒンジ本体５が第１初期位置から所定角度だけ回動すると、球体６６が第１係合凹部６３Ａから脱出して第１回動部材６３の第１可動部材６４との対向面に接触する。この対向面は、第１回動軸線Ｌ１と直交する平面になっている。したがって、当該対向面と球体６６との間には、コイルばね６５の付勢力に応じた摩擦抵抗が発生する。この摩擦抵抗により、受話ケース３が第１係合凹部６３Ａを抜け出てから第１係合凹部６３Ｂに入り込むまでの範囲のうち、両端の所定角度を除いた所定範囲においては、受話ケース３が任意の位置で停止させられる。   When the reception case 3 is rotated from the intermediate position to the call position side, the state where the reception case 3 is stopped at the second rotation position is maintained, and the hinge body 5 is connected to the first initial position side rotation prevention means 9A. It rotates from the first initial position to the first rotation position side against the urging force. When the hinge body 5 rotates by a predetermined angle from the first initial position, the sphere 66 escapes from the first engaging recess 63A and contacts the surface of the first rotating member 63 facing the first movable member 64. This opposing surface is a plane orthogonal to the first rotation axis L1. Therefore, a frictional resistance corresponding to the biasing force of the coil spring 65 is generated between the facing surface and the sphere 66. Due to this frictional resistance, the receiving case 3 is optional in a predetermined range excluding a predetermined angle at both ends of the range from when the receiving case 3 exits the first engaging recess 63A to the first engaging recess 63B. It is stopped at the position.

受話ケース３が通話位置から所定角度（例えば１０°）だけ手前の位置に達すると、換言すればヒンジ本体５が第１回動位置から所定角度だけ手前の位置に達すると、球体６６が第１係合凹部６３Ｂの傾斜面６３ｃに接触するようになる。すると、第１回動位置側回動阻止手段９Ｂの付勢力によってヒンジ本体５が第１回動位置まで自動的に回動させられる。それに伴って、受話ケース３が通話位置まで回動させられる。受話ケース３が通話位置に達すると、球体６６が傾斜面６３ｄに突き当たることによって停止し、受話ケース３が通話位置に停止する。このときには、図１８及び図１７に示すように、球体６６が第１係合凹部６３Ｂの傾斜面６３ｃ、６３ｄに接触し、球体７６が第２係合凹部７３ｂの傾斜面７３ｃ，７３ｄに接触している。   When the receiving case 3 reaches a position that is a predetermined angle (for example, 10 °) from the call position, in other words, when the hinge body 5 reaches a position that is a predetermined angle from the first rotation position, the sphere 66 is moved to the first position. It comes in contact with the inclined surface 63c of the engaging recess 63B. Then, the hinge body 5 is automatically rotated to the first rotation position by the urging force of the first rotation position side rotation prevention means 9B. Along with this, the reception case 3 is rotated to the call position. When the reception case 3 reaches the call position, the sphere 66 stops by hitting the inclined surface 63d, and the reception case 3 stops at the call position. At this time, as shown in FIGS. 18 and 17, the sphere 66 contacts the inclined surfaces 63c and 63d of the first engaging recess 63B, and the sphere 76 contacts the inclined surfaces 73c and 73d of the second engaging recess 73b. ing.

通話位置に停止している受話ケース３は、第１回動位置側停止手段１０Ｂ又は第２回動位置側停止手段１０Ｄの付勢力に抗してさらに回動させて通話位置を越えさせることも可能であるが、受話ケース３は、通話位置を越えて僅かな角度だけ回動すると、受話ケース３の一端部が送話ケース２の一端部に突き当たることによって直ちに停止し、それ以上は同方向へ回動不能になる。受話ケース３が送話ケース２に突き当たったときの位置を通話位置としてもよい。その場合には、受話ケース３が通話位置に達したときに球体６６が傾斜面６３ｄに突き当たる直前の位置に位置するように構成し、受話ケース３を第１回動位置側回動阻止手段９Ｂの付勢力によって送話ケース２に突き当たった状態（通話位置に位置している状態）に維持することが望ましい。   The receiving case 3 stopped at the call position may be further rotated against the urging force of the first rotation position side stop means 10B or the second rotation position side stop means 10D to exceed the call position. Although it is possible, when the reception case 3 rotates by a slight angle beyond the call position, one end of the reception case 3 immediately stops when it abuts against one end of the transmission case 2, and the rest is in the same direction. It becomes impossible to rotate. The position when the reception case 3 hits the transmission case 2 may be set as the call position. In that case, when the reception case 3 reaches the call position, the sphere 66 is configured to be positioned immediately before it hits the inclined surface 63d, and the reception case 3 is configured to prevent the rotation of the first rotation position side 9B. It is desirable to maintain a state of being in contact with the transmission case 2 by the urging force (a state of being located at the call position).

受話ケース３を通話位置から中間位置側へ回動させる場合には、受話ケース３が第２回動位置において停止した状態を維持し、ヒンジ本体５が第１回動位置側回動阻止手段の付勢力に抗して第１回動位置から第１初期位置側へ回動する。ヒンジ本体５が第１初期位置の所定角度（例えば１０°）だけ手前の位置まで回動すると、球体６６が第１係合凹部６３Ａの傾斜面７３ａに接触する。その結果、ヒンジ本体５が第１初期位置側回動阻止手段９Ａの回動付勢力によって第１初期位置まで自動的に回動させられる。第１初期位置に達したヒンジ本体５は、球体６６が第１係合凹部６３Ａの傾斜面６３ｂに突き当たることによって停止し、中間位置に停止する。ヒンジ本体５が第１回動位置から第１初期位置まで回動して停止すると、ヒンジ本体５と一体に回動する受話ケース３が通話位置から中間位置まで回動し、中間位置において停止する。なお、ヒンジ本体５が第１回動位置と第１初期位置との間の両端を除く所定の範囲内においては、前述の場合と同様に、球体６６と第１回動部材６３との間に作用する摩擦抵抗により受話ケース３を任意の位置で停止させることができる。   When the receiving case 3 is rotated from the talking position to the intermediate position side, the receiving case 3 is maintained in the stopped state at the second rotating position, and the hinge body 5 is the first rotating position side rotation preventing means. It rotates from the first rotation position to the first initial position side against the urging force. When the hinge body 5 is rotated to a position in front of the first initial position by a predetermined angle (for example, 10 °), the sphere 66 contacts the inclined surface 73a of the first engagement recess 63A. As a result, the hinge body 5 is automatically rotated to the first initial position by the rotation biasing force of the first initial position side rotation preventing means 9A. The hinge body 5 that has reached the first initial position stops when the sphere 66 abuts against the inclined surface 63b of the first engaging recess 63A, and stops at the intermediate position. When the hinge body 5 rotates from the first rotation position to the first initial position and stops, the reception case 3 that rotates together with the hinge body 5 rotates from the talking position to the intermediate position and stops at the intermediate position. . In the predetermined range excluding both ends between the first rotation position and the first initial position, the hinge main body 5 is between the sphere 66 and the first rotation member 63 in the same manner as described above. The receiving case 3 can be stopped at an arbitrary position by the acting frictional resistance.

受話ケース３を中間位置から折畳位置側へ回動させる場合には、ヒンジ本体５が第１初期位置において停止した状態を維持し、受話ケース３が第２回動位置側回動阻止手段９Ｄの回動付勢力に抗して第２回動位置から第２初期位置側へ回動する。受話ケース３が第２初期位置の所定角度（例えば１０°）だけ手前の位置に達すると、球体７６が第２係合凹部７３Ａの傾斜面７３ａに接触する。この結果、受話ケース３が第２初期位置側回動阻止手段９Ｃの回動付勢力によって自動的に第２初期位置まで回動させられる。受話ケース３は、第２初期位置まで回動すると、第１係合凹部７３Ａの傾斜面７３ｂに突き当たって停止する。このとき、受話ケース３は、折畳位置に達している。これにより、携帯電話機１が元の状態に戻る。   When the reception case 3 is rotated from the intermediate position to the folding position side, the hinge body 5 is maintained in the stopped state at the first initial position, and the reception case 3 is in the second rotation position side rotation preventing means 9D. It rotates from the second rotation position to the second initial position side against the rotation urging force. When the reception case 3 reaches a position in front of the second initial position by a predetermined angle (for example, 10 °), the sphere 76 contacts the inclined surface 73a of the second engagement recess 73A. As a result, the reception case 3 is automatically rotated to the second initial position by the rotation biasing force of the second initial position side rotation preventing means 9C. When the reception case 3 rotates to the second initial position, the reception case 3 abuts against the inclined surface 73b of the first engagement recess 73A and stops. At this time, the reception case 3 has reached the folding position. Thereby, the mobile phone 1 returns to the original state.

折畳位置に停止している受話ケース３は、第１初期位置側停止手段１０Ａ又は第１初期位置側停止手段１０Ｃの回動付勢力に抗してさらに回動させて折畳位置を越えさせることも可能であるが、受話ケース３は、折畳位置を越えて僅かな角度だけ回動すると、受話ケース３の前面３ａが送話ケース２の前面２ａに直ちに突き当たることによって停止し、それ以上は同方向へ回動不能になる。受話ケース３が送話ケース２に突き当たったときの位置を折畳位置としてもよい。その場合には、受話ケース３が折畳位置に達したときに球体７６が傾斜面７３ｂに突き当たる直前の位置に位置するように構成し、受話ケース３を第２初期位置側回動阻止手段９Ｃの付勢力によって送話ケース２に突き当たった状態（折畳位置に位置している状態）に維持することが望ましい。   The reception case 3 stopped at the folding position is further rotated against the rotation biasing force of the first initial position side stopping means 10A or the first initial position side stopping means 10C to exceed the folding position. However, when the reception case 3 is rotated by a slight angle beyond the folding position, the reception case 3 stops immediately by directly contacting the front surface 2a of the transmission case 2 and beyond. Cannot rotate in the same direction. The position when the reception case 3 hits the transmission case 2 may be a folding position. In that case, when the reception case 3 reaches the folding position, the sphere 76 is configured to be positioned immediately before it strikes the inclined surface 73b, and the reception case 3 is configured to prevent the rotation of the reception case 3 from the second initial position side 9C. It is desirable to maintain a state of being in contact with the transmission case 2 by the urging force (a state of being located at the folding position).

このように、この携帯電話機１においては、２軸ヒンジ装置４を用いて送話ケース２と受話ケース３とを回動可能に連結しているが、受話ケース３とヒンジ本体５との回動順序を常に一定にすることができる。したがって、携帯電話機１の使用者が違和感を抱くのを未然に防止することができる。   As described above, in the cellular phone 1, the transmitting case 2 and the receiving case 3 are rotatably connected using the biaxial hinge device 4, but the receiving case 3 and the hinge body 5 are rotated. The order can always be constant. Therefore, it is possible to prevent the user of the mobile phone 1 from feeling uncomfortable.

次に、受話ケース３とヒンジ本体５との回動順序を変更したこの発明の第２の実施の形態について説明する。
この発明の第２実施の形態は、受話ケース３が折畳位置から中間位置を経て通話位置まで回動するときに、まずヒンジ本体５が第１初期位置から第１回動位置まで回動して受話ケース３を中間位置まで回動させた後、受話ケース３が第２初期位置から第２回動位置まで回動することによって受話ケースを通話位置まで回動させるようにしたものである。なお、受話ケース３が通話位置から折畳位置まで回動するときの受話ケース３とヒンジ本体５との回動順序は、上記第１実施の形態と同一である。 Next, a second embodiment of the present invention in which the rotation order of the receiving case 3 and the hinge body 5 is changed will be described.
In the second embodiment of the present invention, when the receiving case 3 rotates from the folding position to the talking position through the intermediate position, the hinge body 5 first rotates from the first initial position to the first rotation position. Then, after the receiving case 3 is rotated to the intermediate position, the receiving case 3 is rotated from the second initial position to the second rotating position, whereby the receiving case is rotated to the talking position. Note that the order of rotation of the reception case 3 and the hinge body 5 when the reception case 3 rotates from the call position to the folding position is the same as that in the first embodiment.

受話ケース３を第２初期位置に停止させた状態で、ヒンジ本体５を第１初期位置から第１回動位置まで回動させ、それによって受話ケース３を中間位置まで回動させるために、第１初期位置側回動阻止手段９Ａの一部を構成する第１係合凹部６３Ａの傾斜面６３ａの傾斜角度α１と、第２初期位置側回動阻止手段９Ｃの一部を構成する第２係合凹部７３Ａの傾斜面７３ａの傾斜各β１との間に、α１＜β１が採用されている。この結果、第２初期位置側回動阻止手段９Ｃの回動阻止力（回動付勢力）が第１初期位置側回動阻止手段９Ａの回動阻止力より大きくなる。したがって、受話ケース３が折畳位置から中間位置まで回動する際には、受話ケース３がヒンジ本体５に対して停止状態を維持し、ヒンジ本体５が第１初期位置から第１回動位置まで回動する。   In a state where the reception case 3 is stopped at the second initial position, the hinge body 5 is rotated from the first initial position to the first rotation position, and thereby the reception case 3 is rotated to the intermediate position. The inclination angle α1 of the inclined surface 63a of the first engaging recess 63A constituting a part of the first initial position side rotation preventing means 9A and the second relationship constituting a part of the second initial position side rotation preventing means 9C. Α1 <β1 is employed between each inclined surface β1 of the inclined surface 73a of the combined recess 73A. As a result, the rotation preventing force (rotation biasing force) of the second initial position side rotation preventing means 9C is larger than the rotation preventing force of the first initial position side rotation preventing means 9A. Therefore, when the reception case 3 rotates from the folding position to the intermediate position, the reception case 3 maintains a stopped state with respect to the hinge body 5, and the hinge body 5 moves from the first initial position to the first rotation position. Rotate until.

受話ケース３が中間位置から通話位置まで回動する際には、ヒンジ本体５が第１回動位置において停止状態を維持し、受話ケース３が第２初期位置から第２回動位置まで回動する。このような回動順序を可能にするために、第１係合凹部６３Ｂの傾斜面６３ｄの傾斜角度α４が、第２係合凹部７３Ａの傾斜面７３ａの傾斜角度β１より大きく設定されている。この結果、第１回動位置側停止手段１０Ｂの回動停止力が、第２初期位置側回動阻止手段９Ｃの回動阻止力より大きくなる。したがって、受話ケース３が中間位置から通話位置まで回動する際には、ヒンジ本体５が停止状態を維持し、受話ケース３が回動する。   When the reception case 3 is rotated from the intermediate position to the call position, the hinge body 5 is maintained in the stopped state at the first rotation position, and the reception case 3 is rotated from the second initial position to the second rotation position. To do. In order to enable such a rotation order, the inclination angle α4 of the inclined surface 63d of the first engaging recess 63B is set to be larger than the inclination angle β1 of the inclined surface 73a of the second engaging recess 73A. As a result, the rotation stopping force of the first rotation position side stop means 10B becomes larger than the rotation prevention force of the second initial position side rotation prevention means 9C. Therefore, when the reception case 3 rotates from the intermediate position to the call position, the hinge main body 5 maintains the stopped state, and the reception case 3 rotates.

この発明の第３実施の形態においては、第２実施の形態とは逆に、受話ケース３が折畳位置から通話位置まで回動する場合には、第１実施の形態と同様に、受話ケース３が第２初期位置から第２回動位置まで回動した後、ヒンジ本体５が第１初期位置から第１回動位置まで回動するようになっている。しかし、受話ケース３が通話位置から折畳位置まで回動する場合には、受話ケース３が第２回動位置から第１回動位置まで回動した後、ヒンジ本体５が第１回動位置から第１初期位置まで回動するようになっている。   In the third embodiment of the present invention, in contrast to the second embodiment, when the reception case 3 rotates from the folding position to the call position, the reception case is the same as in the first embodiment. After 3 rotates from the second initial position to the second rotation position, the hinge body 5 rotates from the first initial position to the first rotation position. However, when the reception case 3 is rotated from the call position to the folding position, the hinge body 5 is moved to the first rotation position after the reception case 3 is rotated from the second rotation position to the first rotation position. To the first initial position.

受話ケース３が通話位置から折畳位置まで回動する際に、受話ケース３、ヒンジ本体５という回動順序を達成するために、まずα２＞β３が採用されている。このような角度関係を採用すると、第１回動位置側回動阻止手段９Ｂの回動阻止力（回動付勢力）が第２回動位置側回動阻止手段９Ｄの回動阻止力より大きくなる。したがって、受話ケース３が通話位置から中間位置側へ回動する際には、ヒンジ本体５が第１回動位置において停止状態を維持する一方、受話ケース３が第２回動位置から第２初期位置まで回動する。   When the receiving case 3 is rotated from the talking position to the folding position, α2> β3 is first adopted in order to achieve the rotating order of the receiving case 3 and the hinge body 5. When such an angular relationship is employed, the rotation prevention force (rotation biasing force) of the first rotation position side rotation prevention means 9B is larger than the rotation prevention force of the second rotation position side rotation prevention means 9D. Become. Therefore, when the receiving case 3 rotates from the talking position to the intermediate position side, the hinge body 5 maintains the stopped state at the first rotating position, while the receiving case 3 moves from the second rotating position to the second initial position. Rotate to position.

受話ケース３が中間位置から折畳位置まで回動する際に、ヒンジ本体５、受話ケース３という回動順序を達成するために、α２＜β４が採用されている。このような角度関係を採用すると、第２初期位置側停止手段１０Ｃの回動停止力（回動付勢力）が第１回動位置側回動阻止手段９Ｂの回動阻止力（回動付勢力）より大きくなる。したがって、受話ケース３が中間位置から折畳位置まで回動する際には、受話ケース３が第２初期位置において停止状態を維持する一方、ヒンジ本体５が第１回動位置から第１初期位置まで回動する。これにより、受話ケース３が中間位置から折畳位置まで回動する。   When the receiving case 3 rotates from the intermediate position to the folding position, α2 <β4 is employed in order to achieve the rotation order of the hinge body 5 and the receiving case 3. When such an angular relationship is employed, the rotation stopping force (rotation biasing force) of the second initial position side stop means 10C is the rotation prevention force (rotation biasing force) of the first rotation position side rotation prevention means 9B. ) Bigger. Therefore, when the reception case 3 rotates from the intermediate position to the folding position, the reception case 3 maintains the stopped state at the second initial position, while the hinge body 5 changes from the first rotation position to the first initial position. Rotate until. Thereby, the reception case 3 rotates from the intermediate position to the folding position.
