For example, the second inclined surface 84b of the second β cam recess Μ is made larger than the first cam. The inclination angle of the second inclined surface 82b of the recessed portion 82 is formed to be more gentle, whereby the second frame body 12 is rotated in the closing direction with respect to the first frame body u with the second pumping 4 as an axis, and in the rotation 'In the turn _ degree is (10). (Including approximately (10).) When the second cam 79 is engaged with the second B cam recess 84, the rotation is temporarily stopped, and the movement angle is 76. That is, the intermediate state in which the second cam convex portion 79 is engaged with the second a cam 83 is stopped. Further, the second inclination _ (away from the (four) cam concave: surface) of the second slanting wheel recessed portion 83 of the first B cam recess 82 is formed such that the second frame body torque is greater than the first torque from the intermediate state, and the case 4 is The shaft is provided with a limit _image shame relative to the second axis by the rotation restricting unit 9, thereby causing the second _12==axis to rotate, and the first shaft 3 is axially closed with respect to the first frame 11 Person 2 = 2 A start at a rotation angle of 0. , that is, the rotation of the -_ n / ° direction 'the closed compact c and the second frame 12 are closed in a closed state; in addition, during the closing operation of the second frame In the middle of the first frame, the second inclined surface 82b of the first B cam recess 82 and the second tilt of the second A cam recess (10) may be formed in such a manner that the first torque is smaller than the second torque. The face can be rotated without the need to rotate the restriction unit 9. The rotation restricting unit 9 is for closing the rotation angles of the first shaft 3 and the second shaft 4, for example, as shown in Figs. 11 to 14c, the rotation restricting unit 9 includes the first rotation restricting unit 91 being coupled to the first shaft 3 and The hinged body 2 and the second rotation restricting unit 92 are disposed on the second shaft 4 and the hinged housing.

The state in which the concave phase is engaged to the state in which the engagement with the first B cam recess is engaged is within the upper rotation range of 76°. The first rotation restricting body 93 is formed in a substantially annular shape, and the inner shape of the first-rotating (four) body 93 is formed so as to be mounted on the outer circumference 2 of the front end portion of the first shaft 3, thereby The first-rotation limit fine-slurry 1_axis 3 (first bracket 35) is rotated, and is disposed on the thief 2 _ surface of the first rotating ram body 93, and at the pin end portion _ opposite 遂: position There is a u-th rotation restricting convex portion extending in the axial direction. The first AA turning convex portion 94 is formed along the first rotation __ to be substantially 22 200946002 circular arc liters, and the surface of the hinge housing 2 opposite to the first rotation restricting body 93 is the first hinge The first two rotation restricting convex portions 95 extending in the axial direction, the first rotation restricting convex portion 95 and the first A rotation restricting convex portion are respectively provided at opposite positions in the vicinity of the hinged branch hole 23 of the outer surface of the support piece 21. The portions 94 are disposed on substantially the same circumference. When the first cam rotation restricting projection 94 and the first B rotation restricting projection 卯 are formed such that the first cam projection 77 is engaged with the first A cam recess 81, the first B rotation restricting projection is located at the first A rotation restricting projection 94. The vicinity of one end portion (sometimes referred to as first end portion 94a) (see FIGS. 11 and 14a), and the hinge housing 2 is opposed from the state in which the first cam lobe 77 is engaged with the first A cam domain 81. When the first bracket 35 (the first shaft 3) is rotated in the opening direction, the first B rotation restricting projection 95 is separated from the first end portion 94a of the first A rotation restricting projection 94 and rotated 76. Thereafter, the first cam convex portion 77 is engaged with the first B cam concave portion 82, and the first B rotation restricting convex portion 95 abuts against the other end portion (sometimes referred to as the second end portion 94b) of the uth rotation restricting convex portion 94. The rotation is thus restricted (refer to 12, FIG. 14b, FIG. 14c), whereby the first rotation restricting unit 91 restricts the range of rotation of the hinge housing 2 relative to the first bracket 35 from the first cam projection 77. The shape of the first cam cam recess 82 is engaged with the first cam cam recess 82. Within the range of rotation. The second rotation restricting unit 92 includes a second rotation restricting body % disposed on the outer circumference of the second shaft 4 between the second bracket 45 and the hinge housing 2; a hinge shell provided on the second rotation restricting body 96 The 2A rotation restricting convex portion 97 on the surface of the body 2 side, and the 2B rotation restricting convex portion 98 provided on the hinge housing 2 and being provided with the second A rotation 23 200946002 to restrict the convex β 97 σ, the second The rotation angle limitation of the rotation restricting unit 92 restricts, for example, the rotation of the face casing 2 with respect to the second bracket 45 from the second cam convex portion 79 and the second A cam recess 4 83. The state is within a range of 104° rotation from the state in which the second cam recess 85 is engaged. The second rotation restricting body 96 is formed in a substantially annular shape, and the inner shape of the second rotation limit 雠% is formed into a substantially elliptical shape that is fitted in a state of being fitted to the outer periphery of the front end portion of the second shaft (10), so that the second rotation restriction The body 96 rotates together with the first shaft 4 (second bracket 45). On the surface of the second rotation restricting body 96 on the side of the hinge housing 2, a second A-rotation-convex portion 97 extending in the axial direction is provided at each of two opposite positions on the peripheral end portion. The 2A rotation restricting convex portion 97 is formed along the second rotation restricting body % into a substantially rounded shape 'and the surface of the hinge housing 2 opposite to the second rotation restricting body %', that is, the second hinged flap 22 The opposite outer side of the hinged floor opening 24 of the outer surface of the hinged floor 24 is provided with an S-rotational projection 98 extending in the axial direction. The 2B rotation-closing convex portion 98 and the 2A rotation limit (four) 〇 portion 97 are provided on substantially the same circumference. The second B rotation restricting convex portion 98 and the second A rotational limit convex portion 97 are formed so that the second A rotation restricting convex portion 97 and the second B rotational restricting convex portion 98 are engaged when the second cam convex portion 79 is engaged with the second A cam concave portion 83 One end portion (sometimes referred to as a first end portion 98a) abuts, so that the rotation of the second bracket 45 (second shaft 4) with respect to the hinge housing 2 in the closing direction is restricted (refer to the figure),

2 and FIG. 14B); further, the second turn rotation restricting convex portion 98 and the first rotation restricting convex portion 97 are formed in a state of being engaged with the second cam convex portion 79 from the second A 24 200946002 cam concave β 83 When the second bracket 45 (second shaft 4) is started to rotate toward the open side with respect to the hinge bribe 2, the second α rotation restricting projection 97 is separated from the first end portion 98a of the second rotation restricting projection 98, and is rotated 104. Thereafter, the second cam convex portion 79 is engaged with the second C cam concave portion 85, and the second end portion of the second AA rotation restricting convex portion 97 2B is closed, and thus the one end portion (sometimes referred to as the second end portion) of the second convex portion (10) is abutted, so that Rotation is restricted (see

..., FIG. 14C) thereby the second rotation restricting unit 92 restricts the range of rotation of the second bracket 45 with respect to the hinge housing 2 from the state in which the second cam projection 79 is engaged with the 83rd to the % cam The concave portion 85 is engaged in the rotation range of ==m. Therefore, when the restriction unit is rotated, the rotation range of the second holder 35 is limited to 76. Further, the rotational extent of the (second shaft 4) with respect to the hinge housing 2 is limited to 1〇4. Thus, the biaxial hinge is mounted =: i.e., the second frame 12 is limited to the second frame with respect to the second frame, for example, the rotation angle is 〇. ~18〇. In the range. The elemental rotation limiting unit 5 has a sliding action limiting unit 22, the sliding action limitation is made in the single operation, the limitation ♦ 丄 - 2: ― is the dynamic rotation action, and the _ action cancellation element 8 also suppresses the first cam convex portion 79 When the second cam recess 78 is disengaged, 25 200946002 or when the first cam lobe 77 is disengaged from the first cam recess 76 and the second cam lobe 79 is engaged with the second cam recess 78, the first cam follower 72 and The respective ends of the two end portions 72b, 74b of the second cam follower 74 (refer to FIG. 6 and thus, at the first cam convex end: the cam recess 76 is engaged and the second cam convex portion 79 is from the second cam When the recess 78 is disengaged and the second bracket 45 is rotated relative to the hinge housing 2 with the second shaft 4 as an axis, it is possible to prevent the first cam lobe 77 from being detached from the first cam recess 76 and the first bracket 35 to be One shaft 3 is a shaft that rotates relative to the hinge housing 2, and the first cam protrusion 77 is disengaged from the first cam recess, and the second cam protrusion 79 is engaged with the second cam recess, so that the first bracket 35 When the first shaft 3 is rotated relative to the hinge housing 2, the second cam projection 79 can be avoided. The second cam recess 78 is disengaged to rotate the second bracket 45 with respect to the hinge housing 2 with the second shaft 4 as an axis. Next, the action of the biaxial hinge device 1 of the present invention and its electronic device 1 will be described. 10 in the unused state, usually a two-fold closed state in which the first frame u and the first frame 12 coincide with each other (refer to 2). At this time, the first cam follower 72 and the second In a state where the cam follower 74 presses the first cam body 71 and the second cam body 73 by the elastic force of the compression spring 75a, respectively, the first cam convex portion 77 is engaged with the first A cam concave portion 81 and the second cam convex portion 79 is engaged. Engaging with the 2A cam recess 83, the first frame 11 and the second frame 12 are kept in a closed state in which they substantially completely coincide with each other. Further, when in the closed state, the first cam convex portion 77 and the first A cam concave portion 81 are in the closed state. Engagement 'However, the card combination is not the first cam convex portion 77 and 26 200946002, the 1A cam recess portion 81 is completely (including substantially completely) fitted, but the front end portion of the first cam convex portion 77 is located at the first cam concave portion Midway of the first inclined surface 81a of 81 In the state (see FIG. 5), since the compression spring 75a applies the elastic force so that the first frame body 重 and the second frame body 12 overlap each other, the first frame body 11 and the second frame body 12 do not shake. , keep closed. ❹

In the case of the sigh of the two sighs, for example, in the state in which the first frame 11 is pressed by hand, the second frame 12 is urged to rotate in the opening direction. The torque is smaller than the second torque. Therefore, the second frame 12 pivots with respect to the first frame 11 in the opening direction with the first shaft 3 as a fulcrum, that is, the first cam follower 72 is moved toward the second cam follower side in the hinge housing 2 against the elastic force of the compression spring 75a while the first cam follower 72 (four) - the cam projection 7 is disengaged from the second cam recess 81, at the first Sliding on the circumferential surface of the cam body 71 (FIG. 6) 'At this time' the second cam convex portion 79 and the second a cam concave portion rib cam convex portion 77 are separated from the first a cam concave portion 81, and 72 and the second cam The two opposite sides 74b of the follower 74 are connected to each other, so that the second cam lobe is disengaged from the cam recess 83, so that the limit = and then the H-to-profit. _二_件心:::移27 200946002 77 enters and engages with the first B cam recess 82, and the second lining a stops with respect to the opening operation of the first frame 11 with the first shaft 3 as an axis, thereby becoming 〇 is the intermediate open state (see FIGS. 3 and 7). At this time, since the first cam convex portion 77 enters the first β cam concave portion, the hitch (chck) feeling is generated, and it is possible to easily grasp whether or not the middle cam is reached. In the open state, the first B rotation restricting projection 95 of the first rotation restricting unit 91 abuts against the second end 94b of the uth rotation restricting projection %, and the hinge housing 2 is opposed to each other. In the first bracket, the first shaft 3) is rotated in the opening direction (refer to Fig. 14b). After the force of the second frame 12 is further rotated in the opening direction from the intermediate open state, the rotation of the hinge housing 2 relative to the first bracket 35 (the first shaft 3) in the opening direction is restricted, this time the second frame 12 is rotated in the opening direction with the second shaft 4 as a fulcrum. That is, the second cam follower 74g: the elastic force of the contraction spring 75a, the first cam follower side crane in the hinge housing 2, and the second cam from the second cam lobe of the scale 74 〇 第 from the 2A cam The recessed portion 83 is disengaged and moves on the circumferential surface of the second cam body 73 (see Fig. 8). And 'the angle of rotation reaches 160. Thereafter, the second cam follower 74 moves in a direction away from the side of the first cam follower 72 under the elastic force of the compression spring 75a, and the second cam convex portion 79 enters and engages with the second B cam recess. The second -12 is stopped by the rotation of the second shaft 4 with respect to the first frame body 从而 to form a first open state (refer to FIGS. 4 and 9). At this time, since the second cam convex portion 79 enters the second B cam concave portion material, a feeling of sensation is generated, which is the state in which the first hit 28 200946002 is opened. Thus, the operation portion 13 such as the keyboard portion provided on the upper surface of the first housing 11 is exposed to the operable state, and the display portion 14 is exposed to the visible state. Therefore, the display portion 14 can be in the horizontally long state. When the electronic device 10 is used, at this time, the first cam convex portion 77 is engaged with the first B cam concave portion and the second cam convex portion 79 is engaged with the second B cam concave portion 84, and the engaged state is maintained by the elastic force of the compression spring 75a. Therefore, it is possible to maintain the display portion 14 in the first open state. Further, the second housing 12 is further rotated in the opening direction with the second shaft 4 as a fulcrum by the action of the second housing 12 being rotated in the opening direction from the first open state, and the rotation angle is 180. Thereafter, the 2A rotation restricting convex portion 97 of the second rotation restricting unit 抵 abuts against the second end portion 98b of the 2B rotation restricting convex portion 98 so that the rotation is stopped (refer to FIG. 14c), at this time, at the first cam The follower member 72 and the second cam follower 74 are pressed by the elastic force of the compression spring 75a on the first cam body 71 and the second cam body 73, respectively, due to the second cam projection 79 and the second C cam. The concave portion 85 is engaged and the first cam convex portion 77 is engaged with the first B cam concave portion 82, so that the first frame body 11 and the second frame body 12 are held in the second open state, and in the second open state, The operation portion 13 such as the keyboard portion provided on the upper surface of the first housing 11 is exposed to the operable state, and the display portion 14 is exposed to the visible state. Therefore, it is also possible to use the electronic device while the display portion 14 is in the laterally long state. 10. Further, in the second open state, although the second cam convex portion 79 is engaged with the second C cam concave portion 85, the engagement is not the second cam convex portion 79 29 200946002 and the second C cam concave portion 85 completely (including substantially complete) The state in which the second cam convex portion 79 is located is located in the middle of the second inclined surface 85a of the second C cam concave portion 85 (see FIG. 1A), whereby the compression spring 75a is used. Since the second housing 12 is opened, that is, the elastic force is applied to the second A rotation restricting projection 97 and the other end of the second B rotation restricting projection 98, the first housing 11 and the second housing 12 do not. Shake, thus remaining in the second open state. Thus, when the electronic device 10 in the closed state is opened, first, the torque difference between the first torque and the second torque is transmitted, so that the second insertion body 12 and the hinge housing 2 are together with the first shaft 3 For the rotation of the fulcrum, after the rotation starts, the mutually opposite end portions 72b, 74b of the first cam follower 72 and the second cam follower 74 abut each other to restrict the rotation of the second shaft 4, due to the second The casing 12 does not rotate about the second shaft 4. Therefore, only the rotation about the first axis 3 is performed until the intermediate opening state, and then the first BB of the first rotation restriction unit 91 is transmitted from the intermediate opening state. The rotation restricting convex portion 95 abuts against the first A rotation restricting convex portion 94, so that the rotational 〇 with the first shaft 3 as the axis is restricted to be performed only to the second shaft 4 until the first open state and the second open state As the rotation of the fulcrum, only the rotation with the first shaft 3 as a fulcrum is performed within the range of the rotation angle of 〇~^, at 76 to 18 〇. Only the rotation with the second shaft 4 as a fulcrum is performed within the range of the rotation angle, so that the opening operation can be always performed in a predetermined order of rotation. When the second casing 12 is returned from the second open state to the original position, that is, the closed state, for example, in a state where the first frame u is pressed by the hand, the second two bodies 12 act to rotate in the closing direction. Thus, the torque is collectively generated on the first shaft 4 of the first shaft 3 and 30 200946002. However, the second torque required to disengage the second cam projection 79 from the second C cam recess 85 is smaller than the first cam. The first torque required when the convex portion 77 is disengaged from the first B cam concave portion 82, that is, the first torque is larger than the second torque, so the second frame body 2 is pivoted with the second axis 4 as a fulcrum relative to the first The frame 11 is rotated in the closing direction. When the rotation angle reaches 160°, the second cam convex portion 79 enters the second B cam concave portion 84 from the first cam recess portion 85, and is engaged with the second B cam concave portion 84 so that the rotation φ is temporarily stopped, but at this time There is also a torque difference as described above, which enables the second frame 12 to continue to rotate in the closing direction with respect to the first frame u with the second shaft 4 as an axis, thus, since the first cam follower 72 and the second cam are Since the both end portions 72b and 74b of the movable member 74 are in contact with each other, the above-described sliding is restricted, and as a result, the first cam convex portion 77 is not detached from the first A cam concave portion 81 (refer to FIG. 8), so the second frame The body 12 is rotated in the closing direction with respect to the first frame 11 with the second shaft 4 as a fulcrum. Also, when the angle of rotation reaches 76. At this time, the second cam convex portion 79 enters and engages with the second A cam recessed portion 83, thereby being in an intermediate closed state (refer to Figs. 3 and 7). At this time, a touch feeling is generated, and the second a rotation restricting convex portion 97 abuts the first end portion 9 of the second B rotation restricting convex portion 98, thereby restricting the second bracket 45 (second casing 12) The second shaft 4 is a rotation of the shaft in the closing direction with respect to the hinge housing 2 (refer to FIG. 1 ), thereby a second bracket when the force of the second housing 12 is further rotated in the closing direction from the intermediate closed state. 45 (the second frame 12) is restricted from the rotation of the hinge housing 2 in the closing direction with the second shaft 4 as a fulcrum, and the second frame 12 is opposed to the hinge housing 2 only with the first shaft 3 as a fulcrum. In the first frame 31 200946002, the body 11 is rotated in the closing direction, and when the rotation angle is zero. At this time, a closed state in which the first cam convex portion 卡 is engaged with the first A cam concave portion 81 and the second frame body 12 and the first pivot body 11 are in close contact with each other and overlaps is formed, so that the rotation is stopped (refer to FIGS. 2 and 5). . & 'When the electronic device 10 in the open state is closed, first, the torque difference between the first torque and the second torque is rotated by the second shaft 4 as a fulcrum, and after the start of the rotation, the second cam is Both ends 72b of the movable member 72 and the first

The both end portions 74b of a cam follower 74 abut against each other to restrict the sliding so as not to rotate with the first shaft 3 as a fulcrum. Therefore, the rotation with the second shaft 4 as a fulcrum is performed until the intermediate closed state, and then, From the intermediate closed state, the second second rotation restricting convex portion 97 and the second second rotation restricting convex portion 98 are transmitted, and only the rotation with the first shaft 3 as a fulcrum is performed until the closed shape L is reached, so that it is at 18 〇 76. In the range of the angle of rotation, only the rotation 'with the second axis 4 as a fulcrum' is performed at 76 to Q. Only within the range of the angle of rotation

One axis 3 is the rotation of the fulcrum' so that the closing action can be performed in a predetermined sequence of rotational motion. Therefore, the biaxial hinge device 1 of the present invention and the electronic device 10 perform __ in a predetermined order of the electronic device 10, and only the first axis 3 is used as a fulcrum with respect to the _ frame during the electronic setting of the _ state. Rotating the first body 12 together with the hinge housing 2 to an intermediate open state, from the open state, the second frame 12 is only pivoted with the second shaft 4 as a fulcrum; the frame 11 is rotated to the first open state or The second open state 'and: 4 only rotates with the first axis 4 as a fulcrum relative to the first frame n to 〇32 200946002. The state 'and further from the intermediate closed state only with the first axis 3 as a fulcrum relative to the first The frame U rotates the second frame 12 together with the hinge housing 2, and as described in detail above, the first frame 1 can be made to have a simple structure in which the number of components is reduced and the cost is reduced. The opening and closing operation of the second housing 12 is performed in a predetermined opening and closing sequence, so that the operability can be improved. Further, the compression spring 75a having a different elastic force can be used to hold the closed state, the first open state, and the second Adjust the holding force of the open state φ . In addition, in the present embodiment, when the second frame 12 is further opened relative to the first frame U from the intermediate open state, the hinge housing 2 is restrained relative to the first axis 3 by the second rotation restricting unit 92. Rotating in the opening direction, and further, when the second frame body 12 is closed from the middle closed angle with respect to the first frame body η, the through-rotation unit 91 restricts the chaining housing 2 from rotating in the closing direction, but In this case, for example, the torque difference between the first torque and the second torque may be transmitted only, and the hinge housing 2 may be restricted from rotating in the opening direction with respect to the first shaft 3 by the sliding action limiting element 8. . Further, in the embodiment of the present invention, when the electronic device Η is turned on in a certain rotation order as follows, only the first axis 3 is used as a fulcrum with respect to the first frame u. The second frame 12 and the hinge housing 2 are rotated to the position of the play, from the second frame (four), with the second axis 4 as a fulcrum, with respect to the first body, rotating to the first game or The second playing position, and when the electronic device 10 in the open state is closed, the second _ gamma second axis 33 200946002 4 is rotated as a fulcrum with respect to the first frame u to an intermediate closed state, and is closed from the middle The state starts to rotate the second frame body 12 and the hinge housing 2 with respect to the first frame body only with the first axis 3 as a fulcrum. However, the rotation sequence is not limited to the rotation order, and the opening and closing may be performed in other rotation order. For example, if the electronic device 1 is turned on in the closed state, the second frame 12 is initially rotated by the second axis 4 as a fulcrum with respect to the first frame u to the intermediate open state. The opening shape '_ begins with the first axis 3 as a fulcrum 〇 relative to the first: frame 11 makes the second frame 12 rotates together with the hinge housing 2 to the open state 'and' closes the electronic device in the playing position 1' with the first axis 3 as a fulcrum relative to the first frame u to make the second frame: with the hinge shell The body 2 is rotated to the middle-closed state, and the second frame body 12 is rotated relative to the first body 11 with the second axis 4 as a fulcrum from the intermediate closed state. As described in detail above, the invention includes

The first to the end of the first frame and to the second frame L ❹ : the first axis and the second axis are opposite to each other with respect to the hinge housing and are set and = Between the first axis and the second axis, there is a rotation control unit control unit, which leads to the 导 晴 峨 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = (4) Based on the rotation of the fixed rotation sequence, the 'shots are _ single, and she is reduced and the cost is reduced by 34, 200946002', so it is most suitable for electronic devices, especially pDA, notebook computers, etc. The above description is only a preferred embodiment of the present invention, but the features of the present invention are not limited thereto, and any changes or modifications that can be easily conceived by those skilled in the art, All of them should be covered by the following patent application scope of the present invention. ❹
