Therefore, in the closed state of the first casing 2 and the second casing 3, only the second casing 3 can be opened and closed with respect to the first casing 2 by the selective rotation restricting means 15. Is possible.

そこで、第２の筐体３を第１の筐体２に対して開くと、第１ヒンジシャフト１０が共に回転し、ロック部材２１の上側の第１カム凸部２１ａが第１ロックカム部材２３の外周に当接しつつ開かれることになるので、この第２の筐体３の開閉操作時には、選択的回転規制手段１５により、第１の筐体２を第２ヒンジシャフト１２と共に回転させることはできない。続いて第２の筐体３を第１の筐体２に対して開いて行くと、最初は第１吸い込み手段１７ａの第１カムフォロワー３０の第１Ａ湾曲カム凸部３０ｂ及び第１Ｂ湾曲カム凸部３０ｃが連結部材２０に設けた第１Ａ湾曲カム凹部２０ｆ及び第１Ｂ湾曲カム凹部２０ｇを脱する際の抵抗に遭遇するが、第１Ａ湾曲カム凸部３０ｂと第１Ｂ湾曲カム凸部３０ｃが第１Ａ湾曲カム凹部２０ｆと第１Ｂ湾曲カム凹部２０ｇを脱出することによって、第２の筐体３は第１の筐体２に対して開かれ、その際に、第１フリクショントルク発生手段１６ａの上部の第１Ａフリクションワッシャー２６と、同じく上部の第２Ａフリクションワッシャー２８とフリクションプレート２５との間にフリクショントルクが発生することから、第２の筐体３は第１の筐体２に対してフリーストップに開かれ、任意の開閉角度で第２の筐体３を第１の筐体２に対して停止保持させることが可能となるものである。尚、この際におけるフリクショントルクは、吸い込み手段１７の第１吸い込み手段１７ａによっても創出されるが、これは補助的なものであり、この場合の主たるフリクショントルクは、フリクショントルク発生手段１６の第１フリクショントルク発生手段１６ａによって創出される。   Therefore, when the second housing 3 is opened with respect to the first housing 2, the first hinge shaft 10 rotates together, and the first cam convex portion 21 a on the upper side of the lock member 21 moves to the first lock cam member 23. Since the second casing 3 is opened while being in contact with the outer periphery, the first casing 2 cannot be rotated together with the second hinge shaft 12 by the selective rotation restricting means 15 during the opening / closing operation of the second casing 3. . Subsequently, when the second casing 3 is opened with respect to the first casing 2, the first A curved cam convex portion 30b and the first B curved cam convex portion of the first cam follower 30 of the first suction means 17a are initially set. The portion 30c encounters resistance when the first A curved cam concave portion 20f and the first B curved cam concave portion 20g provided on the connecting member 20 are removed, but the first A curved cam convex portion 30b and the first B curved cam convex portion 30c are the first. By escaping the 1A curved cam recess 20f and the 1B curved cam recess 20g, the second casing 3 is opened with respect to the first casing 2, and at this time, the upper portion of the first friction torque generating means 16a is opened. Since the friction torque is generated between the first A friction washer 26 and the upper second A friction washer 28 and the friction plate 25, the second casing 3 is connected to the first casing 2. It was opened free stop and one in which it is possible to stop holding the second housing 3 relative to the first housing 2 at any opening angle. The friction torque at this time is also created by the first suction means 17a of the suction means 17, but this is auxiliary, and the main friction torque in this case is the first friction torque generating means 16's first friction torque. It is created by the friction torque generating means 16a.

このようにして、第２の筐体３を第１の筐体２に対してフリーストップに開いて行くと、１８０度開いたところで、図５、図７、図１５、及び図１６に示したように、第１ストッパー手段１９ａの第１ロックカム部材２３の第１ストッパー片２３ｃがスライドガイド部材２２の第１ストッパー部２２ｆに当接することにより、第１ヒンジシャフト１０の回転は規制されるので、第２の筐体３は第１の筐体２に対して１８０度開かれたところで停止する。すると、同時に第１ロックカム部材２３の第１カム凹部２３ｂが、図９に示したように、１８０°回転してロック部材２１の第１カム凸部２１ａの位置に来て、両者の間に間隙ａが生じるので、第１の筐体２の回転（開閉）が許容される状態となる。   In this way, when the second housing 3 is opened to the first housing 2 in a free stop, when the second housing 3 is opened 180 degrees, it is shown in FIGS. 5, 7, 15, and 16. As described above, since the first stopper piece 23c of the first lock cam member 23 of the first stopper means 19a contacts the first stopper portion 22f of the slide guide member 22, the rotation of the first hinge shaft 10 is restricted. The second housing 3 stops when it is opened 180 degrees with respect to the first housing 2. At the same time, as shown in FIG. 9, the first cam recess 23b of the first lock cam member 23 is rotated by 180 ° to come to the position of the first cam protrusion 21a of the lock member 21, and a gap is formed between them. Since a occurs, the rotation (opening / closing) of the first casing 2 is allowed.

尚、第２の筐体３の第１の筐体２に対する１８０度の開成位置から、閉じようとすれば、それは問題なく閉じられる。即ち、第２の筐体３を第１の筐体２に対して閉じ方向へ回転させると、第１ヒンジシャフト１０と共に回転する第１ロックカム部材２３の第１カム凹部２３ｂとロック部材２１の第１カム凸部２１ａとの間には間隙ａが存在するので、第２の筐体３は第１の筐体２に対して閉じることが可能である。一度第２の筐体３を第１の筐体２に対して閉方向へ回転させると、その外周が第１カム凸部２１ａと当接することになるので、ロック部材２１の第２カム凸部２１ｂは第２ヒンジシャフト１２に固定させた第２ロックカム部材２４の第２カム凹部２４ｂと嵌合状態のままとなり、この第２の筐体３の閉成操作時においても、第１の筐体２の回動動作は規制される。   In addition, if it is going to close from the open position of 180 degree | times with respect to the 1st housing | casing 2 of the 2nd housing | casing 3, it will be closed without a problem. That is, when the second housing 3 is rotated in the closing direction with respect to the first housing 2, the first cam recess 23 b of the first lock cam member 23 that rotates together with the first hinge shaft 10 and the first of the lock member 21 are rotated. Since there is a gap a between the one cam projection 21a, the second casing 3 can be closed with respect to the first casing 2. Once the second housing 3 is rotated with respect to the first housing 2 in the closing direction, the outer periphery of the second housing 3 comes into contact with the first cam convex portion 21a. 21b remains in a fitted state with the second cam recess 24b of the second lock cam member 24 fixed to the second hinge shaft 12, and even when the second casing 3 is closed, the first casing The rotational movement of 2 is restricted.

このように第２の筐体３は第１の筐体２に対して０度から１８０度の間で自由に開閉でき、その間、選択的回転規制手段１５により、第１の筐体２の回転は規制されたままである。   In this way, the second casing 3 can be freely opened and closed with respect to the first casing 2 between 0 degrees and 180 degrees, and during that time, the rotation of the first casing 2 is rotated by the selective rotation restricting means 15. Remains regulated.

次に、第１の筐体２は、図１(ｂ)に示したような第２の筐体３との間の閉成状態のときには、上記したように第１ロックカム部材２３の外周が、ロック部材２１の第１カム凸部２１ａと当接しているため、開閉操作を行うことはできないが、第２の筐体３を１８０度開いた後は、開かれた第２の筐体３とは逆方向に回転して１８０度まで回転することが可能となる。即ち、第２の筐体３を１８０度回転させると、図９に示したように、第１ロックカム部材２３の第１カム凹部２３ｂが、１８０度回転してロック部材２１の第１カム凸部２１ａと対向しており、両者の間には間隙ａが生じているので、第２ヒンジシャフト１２に回転を規制して取り付けられている第２ロックカム部材２４の回転が可能となり、第１の筐体２が回転すると、当該第２ロックカム部材２４の外周がロック部材２１の第２カム凸部２１ｂと当接することになるので、第２の筐体３の閉成操作はできなくなる。   Next, when the first casing 2 is in the closed state with the second casing 3 as shown in FIG. 1B, the outer periphery of the first lock cam member 23 is as described above. Since it is in contact with the first cam projection 21a of the lock member 21, the opening / closing operation cannot be performed, but after opening the second casing 3 180 degrees, Can rotate up to 180 degrees in the opposite direction. That is, when the second housing 3 is rotated 180 degrees, the first cam recess 23b of the first lock cam member 23 is rotated 180 degrees and the first cam protrusion of the lock member 21 is rotated as shown in FIG. 21a, and a gap a is formed between them, so that the second lock cam member 24 attached to the second hinge shaft 12 with its rotation regulated can be rotated, and the first housing When the body 2 rotates, the outer periphery of the second lock cam member 24 comes into contact with the second cam convex portion 21b of the lock member 21, so that the second casing 3 cannot be closed.

そこで、第１の筐体２を第２の筐体３に対して第２の筐体３のときとは反対方向へ回転させると、第２ヒンジシャフト１２が共に回転し、ロック部材２１の下側の第２カム凸部２１ｂが第２ロックカム部材２４の外周に当接しつつ開かれることになるので、選択的回転規制手段１５により、第２の筐体３は閉方向へ回転させることができなくなる。第１の筐体２を第２の筐体３に対して回転させて行くと、最初は第２吸い込み手段１７ｂの第２カムフォロワー３１の第２Ａ湾曲カム凸部３１ｂと第２Ｂ湾曲カム凸部３１ｃが、連結部材２０に設けた第２Ａ湾曲カム凹部２０ｈと第２Ｂ湾曲カム凹部２０ｉを脱する際の抵抗に遭遇するが、第２カムフォロワー３１の第２Ａ湾曲カム凸部３１ｂと第２Ｂ湾曲カム凸部３１ｃが第２Ａ湾曲カム凹部２０ｈと第２Ｂ湾曲カム凹部２０ｉを脱出することによって、第１の筐体３は第２の筐体３に対して回転し、その際に、第２フリクショントルク発生手段１６ｂの下部の第２Ｂフリクションワッシャー２９及び同じく下部の第１Ｂフリクションワッシャー２７とフリクションプレート２５との間にフリクショントルクが発生することから、第１の筐体２は第２の筐体３に対してフリーストップに回転し、任意の回転（開閉）角度で第１の筐体２を第２の筐体３に対して停止保持させることが可能となるものである。尚、この際におけるフリクショントルクは、吸い込み手段１７の第２吸い込み手段１７ｂによっても創出されるが、これは補助的なものであり、この時の主たるフリクショントルクは、フリクショントルク発生手段１６の第２フリクション手段１６ｂによって創出される。   Therefore, when the first casing 2 is rotated relative to the second casing 3 in the opposite direction to that of the second casing 3, the second hinge shaft 12 rotates together, and the lower part of the lock member 21 is rotated. Since the second cam projection 21b on the side is opened while being in contact with the outer periphery of the second lock cam member 24, the second casing 3 can be rotated in the closing direction by the selective rotation restricting means 15. Disappear. When the first casing 2 is rotated with respect to the second casing 3, first, the second A curved cam convex portion 31b and the second B curved cam convex portion of the second cam follower 31 of the second suction means 17b. 31c encounters resistance when removing the second A curved cam concave portion 20h and the second B curved cam concave portion 20i provided in the connecting member 20, but the second A curved cam convex portion 31b and the second B curved portion of the second cam follower 31 are encountered. When the cam convex portion 31c escapes from the second A curved cam concave portion 20h and the second B curved cam concave portion 20i, the first casing 3 rotates with respect to the second casing 3, and at this time, the second friction The friction torque is generated between the second B friction washer 29 at the lower part of the torque generating means 16b and the first B friction washer 27 at the lower part of the torque generating means 16 and the friction plate 25. 2 rotates freely with respect to the second housing 3 and can stop and hold the first housing 2 with respect to the second housing 3 at an arbitrary rotation (opening / closing) angle. It is. The friction torque at this time is also created by the second suction means 17b of the suction means 17, but this is auxiliary, and the main friction torque at this time is the second torque of the friction torque generation means 16. Created by the friction means 16b.

このようにして、第１の筐体２を第２の筐体３に対して第２の筐体３の開成方向とは反対の方向へフリーストップに回転させて行くと、１８０度回転させたところで、図７と図１３、及び図１６に示したことから解るように、第２ストッパー手段１９ｂを構成する第２ロックカム部材２４の第２ストッパー片２４ｃが、スライドガイド部材２２の第２ストッパー部２２ｇに当接することにより、第２ヒンジシャフト１２の回転は規制されるので、第１の筐体２は第２の筐体３に対して１８０度開かれたところで停止する。この状態が、ちょうど第１の筐体２と第２の筐体３が互いに重なり合った状態である。   In this way, when the first casing 2 is rotated free-stopping in the direction opposite to the opening direction of the second casing 3 with respect to the second casing 3, it is rotated 180 degrees. By the way, as can be seen from FIGS. 7, 13, and 16, the second stopper piece 24 c of the second lock cam member 24 constituting the second stopper means 19 b is the second stopper portion of the slide guide member 22. Since the rotation of the second hinge shaft 12 is restricted by coming into contact with 22g, the first casing 2 stops when it is opened 180 degrees with respect to the second casing 3. This state is just a state in which the first housing 2 and the second housing 3 overlap each other.

尚、第１の筐体２を第２の筐体３に対する１８０度の開成位置より、元位置に戻そうとすれば、それは問題なく戻せる。即ち、図１０に示した状態より、第１の筐体２を第２の筐体３に対して閉じ方向へ回転させると、第２ヒンジシャフト１２と共に回転する第２ロックカム部材２４の外周は、ロック部材２１の第２カム凸部２１ｂと当接した状態にあり、ロック部材２１の第１カム凸部２１ａは第１ヒンジシャフト１０に固定させた第１ロックカム部材２３の第１カム凹部２３ｂと嵌合状態のままであるので、第１の筐体２を元位置の方向へ回転させることが可能となる。この際には、第２の筐体３は、第１ヒンジシャフト１０に固定させた第１ロックカム部材２３の第１カム凹部２３ｂが、ロック部材２１の第１カム凸部２１ａと嵌合状態のままであるので、第２の筐体３の開閉操作は規制されたままである。   In addition, if it is going to return the 1st housing | casing 2 to the original position from the open position of 180 degree | times with respect to the 2nd housing | casing 3, it can return without a problem. That is, from the state shown in FIG. 10, when the first housing 2 is rotated in the closing direction with respect to the second housing 3, the outer periphery of the second lock cam member 24 that rotates together with the second hinge shaft 12 is The first cam convex portion 21 a of the lock member 21 is in contact with the second cam convex portion 21 b of the lock member 21, and the first cam concave portion 23 b of the first lock cam member 23 fixed to the first hinge shaft 10. Since the fitting state is maintained, the first casing 2 can be rotated in the direction of the original position. At this time, in the second housing 3, the first cam concave portion 23 b of the first lock cam member 23 fixed to the first hinge shaft 10 is in a fitted state with the first cam convex portion 21 a of the lock member 21. Therefore, the opening / closing operation of the second housing 3 remains restricted.

このように第１の筐体２は、第２の筐体３が１８０度開かれた状態においては、第２の筐体３に対して０度から１８０度の間で自由に回転させることができ、その間、第２の筐体３の開閉操作は選択的回転規制手段１５により規制されたままである。以上に説明から明らかなように、第２の筐体３と第１の筐体２は、選択的回転規制手段１５により選択的に開閉され、一方の開閉操作時には他方の開閉操作は規制される。   As described above, the first casing 2 can be freely rotated between 0 degree and 180 degrees with respect to the second casing 3 in a state where the second casing 3 is opened 180 degrees. In the meantime, the opening / closing operation of the second housing 3 remains restricted by the selective rotation restricting means 15. As is apparent from the above description, the second casing 3 and the first casing 2 are selectively opened and closed by the selective rotation restricting means 15, and the other opening / closing operation is restricted during one opening / closing operation. .

以上に説明した実施例１に係る発明は、第１の筐体と第２の筐体が互いに重ね合わされた閉成状態のときには、第１の筐体２に対して第２の筐体３のみが開閉でき、第２の筐体３第１の筐体２に対して開いたときには、その開閉操作中は第１の筐体２を第２の筐体３に対して開閉(或は回転)することができない。また、第１の筐体２は第２の筐体３を第１の筐体２に対して１８０度開いた後において、第１の筐体２を第２の筐体３に対して開閉(或は回転)することができ、その開閉操作中は第２の筐体３は第１の筐体２に対して開閉できない構成である。   In the invention according to the first embodiment described above, when the first casing and the second casing are in the closed state, only the second casing 3 is compared with the first casing 2. Can be opened and closed, and when the second casing 3 is opened with respect to the first casing 2, the first casing 2 is opened and closed (or rotated) with respect to the second casing 3 during the opening / closing operation. Can not do it. The first casing 2 opens and closes the first casing 2 with respect to the second casing 3 after the second casing 3 is opened 180 degrees with respect to the first casing 2 ( The second housing 3 cannot be opened and closed with respect to the first housing 2 during the opening / closing operation.

これに対して、図２０〜図２２に示した実施例２に係る２軸ヒンジは、第１の筐体と第２の筐体が互いに重ね合わされた閉成状態のときには、第１の筐体２も第２の筐体３も共に開閉操作可能であり、どちらか一方の筐体を他方の筐体に対して開閉操作したときには、他方の筐体の開閉操作を行うことができず、さらに、第１の筐体２と第２の筐体３が共に所定の開成角度(或は回転角度)となったときには、第１の筐体２と第２の筐体３のどちらも開閉操作でき、一度どちらかの筐体を開閉操作したときには、他方の筐体の開閉操作ができないようにしたものである。   On the other hand, when the biaxial hinge according to the second embodiment shown in FIGS. 20 to 22 is in the closed state in which the first housing and the second housing are overlapped with each other, the first housing Both the second housing 3 and the second housing 3 can be opened and closed. When one of the housings is opened and closed with respect to the other housing, the other housing cannot be opened and closed. When both the first casing 2 and the second casing 3 reach a predetermined opening angle (or rotation angle), both the first casing 2 and the second casing 3 can be opened and closed. In this case, once one casing is opened / closed, the other casing cannot be opened / closed.

即ち、図２０〜図２２によれば、この実施例２に係る２軸ヒンジ４０の第１ロックカム部材４１と第２ロックカム部材４２の外周には１８０度間隔で、それぞれ第１Ａカム凹部４１ｂ及び第１Ｂカム凹部４１ｃと、第２Ａカム凹部４２ｂ及び第２Ｂカム凹４２ｃ部が設けられ、第１ヒンジシャフト１０と第２ヒンジシャフト１２の各第２変形軸部１０ｆと１２ｆに、それぞれの変形挿通孔４１ａ、４２ａを挿通係合させている。尚、指示記号の同じものは先の実施例１と同じ部材を表している。   That is, according to FIGS. 20 to 22, the outer circumferences of the first lock cam member 41 and the second lock cam member 42 of the biaxial hinge 40 according to the second embodiment are spaced apart by 180 degrees from the first A cam recess 41 b and the second lock cam member 42. A 1B cam recess 41c, a second A cam recess 42b, and a second B cam recess 42c are provided, and each of the second deformation shaft portions 10f and 12f of the first hinge shaft 10 and the second hinge shaft 12 has a respective deformation insertion hole. 41a and 42a are inserted and engaged. The same reference symbols denote the same members as those in the first embodiment.

したがって、図示してない第１の筐体と第２の筐体が共に閉じられた状態においては、図２０に示したように、ロック部材２１の第１カム凸部２１ａと第２カム凸部２１ｂが、それぞれ第１ロックカム部材４１と第２ロックカム部材４２の第１Ｂカム凹部４１ｃと第２Ａカム凹部４２ｂと対向し、間隙ｂが生じていることから、第１ヒンジシャフト１０と第２ヒンジシャフト１１のどちらも回転可能であるので、第１の筐体と第２の筐体はどちらも開閉操作可能である。   Therefore, in a state where the first casing and the second casing (not shown) are both closed, as shown in FIG. 20, the first cam protrusion 21a and the second cam protrusion of the lock member 21 21b opposes the first B cam recess 41c and the second A cam recess 42b of the first lock cam member 41 and the second lock cam member 42, respectively, and a gap b is formed, so that the first hinge shaft 10 and the second hinge shaft Since both 11 can rotate, both the first housing and the second housing can be opened and closed.

しかるに、第１の筐体と第２の筐体のどちらかの筐体の開閉操作がなされると、回転するどちらかの第１ヒンジシャフト１０と第２ヒンジシャフト１２の回転動作に伴って、第１ロックカム部材４１か第２ロックカム部材４２のどちらかが共に回転することになり、この回転動作により、ロック部材２１の第１カム凸部２１ａか第２カム凸部２１ｂが各第１ロックカム部材４１か第２ロックカム部材４２のいずれか一方の外周と接することになることから、他方の回転は規制されることになる。   However, when the opening / closing operation of either the first casing or the second casing is performed, along with the rotating operation of either the first hinge shaft 10 or the second hinge shaft 12 that rotates, Either the first lock cam member 41 or the second lock cam member 42 rotates together, and this rotation operation causes the first cam convex portion 21a or the second cam convex portion 21b of the lock member 21 to move to the first lock cam member. 41 or the second lock cam member 42 is in contact with the outer periphery of the second lock cam member 42, so that the other rotation is restricted.

図２１は、第２の筐体３が第１の筐体２に対して１８０度開かれた状態を示しており、この状態は、第２の筐体３を閉成方向へ回転させて元位置へ戻すことが可能な状態であり、同時に第２の筐体３を第１の筐体２に対して１８０度開いた状態において、第１の筐体２を第２の筐体３に対して反対方向へ回転させることのできる状態である。勿論、この状態においても、第１の筐体２か第２の筐体３のどちらかが回転させられると、他方の回転は規制される。   FIG. 21 shows a state in which the second housing 3 is opened 180 degrees with respect to the first housing 2, and this state is obtained by rotating the second housing 3 in the closing direction. In a state where the second casing 3 can be returned to the position and at the same time the second casing 3 is opened 180 degrees with respect to the first casing 2, the first casing 2 is moved relative to the second casing 3. And can be rotated in the opposite direction. Of course, even in this state, when either the first casing 2 or the second casing 3 is rotated, the other rotation is restricted.

そして、図２２に示したように、第１の筐体２と第２の筐体３がともに１８０度開かれた状態においても、ロック部材２１の第１カム凸部２１ａと第２カム凸部２１ｂがそれぞれ第１ロックカム部材４１と第２ロックカム部材４２の第１Ｂカム凹部４１ｃと第２Ｂカム凹部４２ｃと対向していることから、第１ヒンジシャフト１０と第２ヒンジシャフト１２のどちらも回転可能であるので、第１の筐体と第２の筐体はどちらも開閉操作可能である。しかるに、第１の筐体か第２の筐体のどちらか一方が開閉操作中においては、前述したように、第１ロックカム部材４１と第２ロックカム部材４２の各外周が、ロック部材２１の第１カム凸部２１ａと第２カム凸部２１ｂのどちらかと当接することになるため、他方の開閉操作は規制されることになる。   As shown in FIG. 22, even when the first housing 2 and the second housing 3 are both opened 180 degrees, the first cam convex portion 21a and the second cam convex portion of the lock member 21 are used. Since 21b faces the first B cam recess 41c and the second B cam recess 42c of the first lock cam member 41 and the second lock cam member 42, both the first hinge shaft 10 and the second hinge shaft 12 are rotatable. Therefore, both the first casing and the second casing can be opened and closed. However, when either the first casing or the second casing is being opened / closed, the outer periphery of each of the first lock cam member 41 and the second lock cam member 42 is the first of the lock member 21 as described above. Since the first cam convex portion 21a or the second cam convex portion 21b comes into contact, the other opening / closing operation is restricted.

このように実施しても、第１の筐体２と第２の筐体３の開閉操作に一定の規則性が生まれ、本発明の目的は達成できる。尚、以上は一例であって、このものに限定されず、第１カム凹部２３ｂと第２カム凹部２４ｂを設ける位置を、第１及び第２ロックカム部材２３と２４の任意の外周に設けることは可能である。   Even if it implements in this way, a fixed regularity will arise in the opening / closing operation of the 1st housing | casing 2 and the 2nd housing | casing 3, and the objective of this invention can be achieved. It should be noted that the above is an example, and the present invention is not limited to this, and the position where the first cam recess 23b and the second cam recess 24b are provided on the outer periphery of the first and second lock cam members 23 and 24 is arbitrary. Is possible.

よって、以上の説明から明らかなように、本願発明に係る２軸ヒンジ４と４０は、第１の筐体２と第２の筐体３をそれぞれ第１ヒンジシャフト１０と第２ヒンジシャフト１２を介して交互に１８０度ずつ回転させて合計で３６０度の開閉操作を可能としたものであるが、その開閉角度にとくに限定はない。   Therefore, as is clear from the above description, the biaxial hinges 4 and 40 according to the present invention have the first casing 2 and the second casing 3 connected to the first hinge shaft 10 and the second hinge shaft 12, respectively. However, the opening / closing operation of 360 degrees in total is possible by alternately rotating 180 degrees, but the opening / closing angle is not particularly limited.

そして、ノートパソコンをそれ本来の用い方で用いることができた上で、第１の筐体を第２の筐体に対して同一方向に折り曲げて、略Ｌ時形状にしたり、山形状にしたり、重ね合わせて平板状としたりして、第２の筐体を操作者側に向けてタブレットとして種々多様な用い方をすることができるものである。   Then, after the notebook computer can be used in its original way, the first housing is bent in the same direction with respect to the second housing to form a substantially L hour shape or a mountain shape. It is possible to use the tablet in a variety of ways as a tablet by superimposing it into a flat plate shape and directing the second casing toward the operator side.

以上の説明から明らかなように、本発明は以上説明したもの以外に、例えば、第１及び第２弾性手段３２、３３をフリクショントルク発生手段１６と吸い込み手段１７の両機構に作用せしめることが可能となったので、効率の良いものとなっており、かつ、ロック部材とロックカム部材をその外形を用いたり、吸い込み手段のカム形状を任意に変えることが容易となって、カム特性の設計が容易となったため、第２の筐体３の第１の筐体２に対する開成角度を特定の角度においてふらつきの生じないようにしたり、特定の開成角度において吸い込み機能をもたせることもできるものである。   As is apparent from the above description, the present invention can cause the first and second elastic means 32 and 33 to act on both the friction torque generating means 16 and the suction means 17 in addition to those described above, for example. As a result, it is efficient and it is easy to use the outer shape of the lock member and the lock cam member, or to arbitrarily change the cam shape of the suction means, and to easily design the cam characteristics Therefore, the opening angle of the second housing 3 with respect to the first housing 2 can be prevented from wobbling at a specific angle, or a suction function can be provided at the specific opening angle.

尚、その他の実施例としては、連結部材２０に設ける各第１Ａ湾曲カム凹部２０ｆ及び第１Ｂ湾曲カム凹部２０ｇと第２Ａ湾曲カム凹部２０ｈ及び第２Ｂ湾曲カム凹部２０ｉと、第１カムフォロアー３０や第２カムフォロアー３１に設ける第１Ａ湾曲カム凸部及び第１Ｂ湾曲カム凸部と第２Ａ湾曲カム凸部及び第２Ｂ湾曲カム凸部は、これらを連結部材２０と第１及び第２カムフォロアー３０、３１の軸心部から外周へ放射状に設けたカム凸部とカム凹部に変えることは可能である。また、皿バネから成る第１及び第２弾性手段３２、３３は、これをスプリングワッシャー、圧縮コイルスプリング、弾性を備えたゴムを始とする合成樹脂製のものなどに代えることができ、第１及び第２締付ナット３６、３７は、第１ヒンジシャフト１０と第２ヒンジシャフト１２の端部をかしめることによって代えることが可能である。さらに、各第１カム凹部及び第２カム凹部の設置位置を変えることにより、第１の筐体が第２の筐体より先に開閉することができるように構成することも可能である。また、ヒンジケース１４は、これがなくともとくに２軸ヒンジ４、５、及び４０の機能に支障は生じないが、このヒンジケースがあると、２軸ヒンジを端末機器へ取り付けた際に選択的回転規制手段や、フリクショントルク発生手段、吸い込み手段等が外部へ露出することがないので、外観状すっきりとしたものになるという利点がある。   As other embodiments, the first A curved cam recesses 20f and the first B curved cam recesses 20g, the second A curved cam recesses 20h and the second B curved cam recesses 20i provided in the connecting member 20, the first cam follower 30, The first A curved cam convex portion, the first B curved cam convex portion, the second A curved cam convex portion and the second B curved cam convex portion provided on the second cam follower 31 are connected to the connecting member 20 and the first and second cam follower 30. , 31 can be changed into cam convex portions and cam concave portions provided radially from the outer periphery to the outer periphery. Further, the first and second elastic means 32, 33 made of a disc spring can be replaced with a spring washer, a compression coil spring, a synthetic resin material such as rubber having elasticity, etc. The second tightening nuts 36 and 37 can be replaced by caulking the end portions of the first hinge shaft 10 and the second hinge shaft 12. Furthermore, the first housing can be configured to be opened and closed before the second housing by changing the installation positions of the first and second cam recesses. In addition, the hinge case 14 does not interfere with the functions of the biaxial hinges 4, 5, and 40 without this, but with this hinge case, the biaxial hinge is selectively rotated when the biaxial hinge is attached to the terminal device. Since the regulating means, the friction torque generating means, the suction means and the like are not exposed to the outside, there is an advantage that the appearance is clear.

本発明は以上のように構成したので、とくにノートパソコンのような端末機器やその他のもので、第１の筐体と第２の筐体を相対的に１８０度以上開閉させる場合の２軸ヒンジとして好適に用いられるものであるが、とくにノートパソコンを同時にタブレットとしても用いるものに用いて好適である。   Since the present invention is configured as described above, the biaxial hinge in the case where the first casing and the second casing are opened and closed relative to each other by 180 degrees or more, particularly in a terminal device such as a notebook personal computer or the like. However, it is particularly suitable for use in which a notebook personal computer is also used as a tablet at the same time.
