In the biaxial hinges described in Patent Documents 1 and 2, since the number of components is large and the structure is complicated, there is a problem that the manufacturing cost is high, and in addition, the first shaft attached to the base bracket is mounted on the support bracket. The second support piece attached to the mounting bracket is attached to the two support pieces of the frame, and is attached to a substantially central portion of the substrate portion of the support bracket in the longitudinal direction. Therefore, when the display device is rotated relative to the apparatus main body through the second shaft, the second shaft acts on the substrate portion in a direction in which the second shaft is stretched from the substrate portion, so that a tensile load is applied to the substrate portion, and the substrate portion is The ends will be bent in a direction close to each other. In order to ensure the strength of the load, it is necessary to thicken the thickness of the substrate portion. As described above, when the thickness of the substrate portion is increased, the length of the support bracket (the length in the longitudinal direction) becomes long, and there is a problem that the support bracket is enlarged. In other words, the support bracket is formed so that the both end portions of the elongated substantially rectangular flat plate are bent in a direction substantially orthogonal to each other to form a cross section. In the shape of a word, when thickening the thickness of the substrate portion, it is necessary to use a substrate having a thick thickness.

This is because, in the closed state, since the display device and the apparatus main body are in close contact with each other, the range in which the display device is rotated in the longitudinal direction with respect to the apparatus main body as the axis is restricted, and, in the open state, the display is performed. The device and the device body are engaged with each other such that the range of rotation is limited. That is, since the rotation range cannot be restricted only by the insufficient strength of the biaxial hinge, the engagement portions that are engaged with each other in the open state are provided on the display device and the apparatus main body, respectively.

At 0° and 90°, it is fully engaged, thereby holding the display device 12 at the position relative to the device body 11, and at -135~-100°, -80~-10°, 10~80°, and 100~135 Friction is generated in the second rotation range of ° to be in a free stop state, that is, the second cam convex portion 65 and the second cam concave portion 64 are formed to have a second rotation angle of -90° with respect to the apparatus main body 11 of the display device 12, The 0° and 90° are completely engaged; and the second cam convex portion 65 and the second cam concave portion 64 are formed as the protruding surface 65a of the second cam convex portion 65 and the second cam concave portion 64 of the second cam portion 62.

In this state, for example, the display unit 12 may be mounted on the display unit 13 as an outer surface. The mounting bracket 31 is mounted, and the second cam convex portion 65 and the second cam concave portion 64 are formed to rotate in the second rotation range of the second rotation angle of -135 to 135° at -90°, 0. ° and 90° angles are fully engaged, but are not limited thereto.

In addition, a second rotation range limiting unit 9 for restricting the second rotation range in which the mounting bracket 31 of the mounting member 3 is pivoted with respect to the support bracket 40 of the support member 4 about the second shaft 6 may be provided, that is, The second rotation range restricting unit 9 is a member for restricting the second rotation range in which the display device 12 is rotated about the second shaft 6 with respect to the apparatus main body 11, and the second rotation range restricting unit 9 is capable of restricting the second rotation range, that is, The second A-rotation range restricting unit that is provided on the second shaft 6 and the second B-rotation range restricting unit that is engaged with the second A-rotation range restricting unit are configured, for example.

The second rotation range restricting protrusion 92 is formed, respectively, when the second rotation range restricting protrusion 91 and the second rotation range restricting protrusion 92 are respectively formed to be the second rotation range restricting convex portion 91 when the second rotation angle is -135°.

Next, the action of the first biaxial hinge 1 and the electronic device 10 according to the present invention will be described.

In the closed state in which the apparatus main body 11 and the display device 12 are overlapped with each other, the first rotation angle is 0°, the first cam convex portion 87 and the first cam concave portion 86 are engaged, and the dish shape is used in such a manner that the engagement is performed. The spring biases the first cam body 82 toward the first cam portion 81 side, and the second rotation angle is 0°, and the second cam convex portion 65 engages with the second cam concave portion 64, and at the same time, performs the engagement. Since the second cam body 63 is biased toward the second cam portion 62 by the compression spring, the apparatus main body 11 and the display device 12 are kept in a closed state (see FIG. 1a); in addition, in order to maintain the closed state more reliably Other locking mechanisms can also be set.

In order to use the electronic device 10 in the closed state in a state where the display device 12 is turned on, for example, the display device 12 is rotated about the first A-axis 51 and the first B-axis 52 with respect to the device body 11, and at this time, the first A-axis is rotated. The first flat portion 71a of the range restricting portion 71 is in contact with the surfaces of the reinforcing plates 7a and 7b (see FIG. 3b), and the semicircular portion 71c of the first A-turning range restricting portion 71 is in sliding contact with the surfaces of the reinforcing plates 7a and 7b. Further, when the display device 12 is rotated relative to the apparatus main body 11 until the first rotation angle becomes 180°, the second planar portion 71b of the first A-turning range restricting portion 71 is respectively added The surfaces of the strong plates 7a, 7b are in contact with each other, so that the rotation is stopped (refer to Fig. 1b). Thus, when the first rotational angle is rotated to 180°, the second planar portion 71b of the 1A rotation range restricting portion 71 is in contact with the surfaces of the reinforcing plates 7a, 7b, respectively, and the first cam convex portion 87 and the first cam concave portion 86 are 86 The engagement is such that the apparatus body 11 and the display device 12 remain in the open state.

Further, when the display device 12 is rotated about the first A-axis 51 and the first B-axis 52 with respect to the apparatus main body 11, the first cam convex portion 87 is separated from the first cam concave portion 86 if the first rotational angle exceeds 10°. Therefore, the protruding surface 87a of the first cam convex portion 87 slides on the surface while being in surface contact with the cam surface 81a of the first cam portion 81, whereby frictional torque is generated between the device body 11 and the display device 12. Therefore, when the rotation of the display device 12 is stopped, the display device 12 is stopped at the position by the friction torque, and therefore, the display device 12 can be stopped in the first rotation range of 10° to 170° with respect to the apparatus main body 11. At the desired angle.

Further, when the display device 12 is rotated about the first A-axis 51 and the first B-axis 52 with respect to the device body 11, the display device 12 can be further rotated about the second axis 6 with respect to the device body 11, for example Further, the display device 12 can be rotated relative to the apparatus main body 11 by the first A-axis 51 and the first B-axis 52 to an open state in which the first rotation angle is 180°, and the display device 12 can be further made second with respect to the apparatus main body 11. The shaft 6 is respectively rotated in two directions, the rotation being limited by the second rotation range limiting unit 9 to a second rotation angle of ±135°, respectively, when the display device 12 is made with the second shaft 6 with respect to the apparatus body 11 When the shaft is rotated by 90° in two directions, the second cam convex portion 65 is engaged with the second cam concave portion 64 to be held at In this state, the state in which the display device 12 is level is the state in which the display unit 13 faces upward or downward.

Moreover, when the display device 12 is rotated about the second axis 6 with respect to the device body 11, the second rotation angle is -135° to -100°, -80° to -10°, 10° to 80°, And 100° to 135°, the second cam convex portion 65 is detached from the second cam concave portion 64, and the front end surface of the second cam convex portion 65 is in surface contact with the cam surface of the second cam portion 62 on the surface. Sliding, whereby frictional torque is generated between the apparatus main body 11 and the display device 12, so when the rotation of the display device 12 is stopped, the display device 12 is stopped at the position by the friction torque, so that the display device can be made 12 is stopped with respect to the apparatus main body 11 at a desired angle in a range of second rotation angles of -135° to -100°, -80° to -10°, 10 to 80 degrees, and 100 to 135 degrees.

Therefore, for example, in a state where the apparatus main body 11 is held by one hand and fixed, the display device 12 is grasped with the other hand, and the display device 12 is oriented with the first A-axis 51 and the first B-axis 52 with respect to the apparatus main body 11. When the shaft is rotated and opened, the display device 12 is further rotated about the second shaft 6 with respect to the apparatus main body 11, whereby the angle of the display portion 13 can be adjusted, and the display portion 13 can be easily adjusted to the time of photographing or the like. A location that is easy to see as a large viewfinder.

In this manner, when the display device 12 is rotated about the first A-axis 51 and the first B-axis 52 with respect to the apparatus main body 11, and the display device 12 is rotated about the second shaft 6 with respect to the apparatus main body 11, in particular, When the display device 12 is rotated with respect to the apparatus main body 11 with the second shaft 6 as an axis, The plate portion 41 acts to force the second shaft 6 of the second rotating mechanism to be released from the support plate portion 41 of the support bracket 40, that is, a tensile load acts on the support plate portion 41, so that the support plate Both side portions of the portion 41 are to be bent toward each other. However, since the reinforcing plates 7a and 7b are attached to the inner surface of the support plate portion 41, the support plate portion 41 is not bent, so that the support plate portion 41 may not be added. The thickness is thus shortened by the length of the support bracket 40. When the thickness of the support plate portion 41 is increased, since the support bracket 40 is formed by bending both end portions of the substrate, the thickness of the bracket portions 42a and 42b is also increased, and the length of the support bracket 40 is lengthened. However, since the reinforcing plates 7a and 7b are attached to the inner surface of the support plate portion 41, the thickness of the bracket portions 42a and 42b does not become thick, so that the length of the support bracket 40 can be shortened, so that the number of components and the cost can be reduced. It is possible to reduce the required strength of the support plate portion 41 and to reduce the size of the support bracket 40. As a result, the size of the first biaxial hinge 1 can be reduced.

Further, the first rotation range restricting means 70 is formed such that the first A rotation range restricting portion 71 is provided on the outer periphery of the flange portion 51a of the first A-axis 51 and the flange portion 52a of the first B-axis 52, and is transmitted through the first A-turn range limitation. The portions 71 are in sliding contact with the surfaces of the two reinforcing plates 7a, 7b, respectively, so that the portions that are engaged with the first A-turning range restricting portion 71 when the first rotational range is restricted are the reinforcing plates 7a, 7b, and are not directly connected to the supporting bracket. 40 or the like is associated with each other, that is, the flange portions 51a and 52a of the two first A-axis 51 and the first B-axis 52 are used as stoppers, and by making the two stoppers respectively and the reinforcing plate 7a, The surface sliding contact (engagement) of 7b can increase the face for limiting the first range of rotation, and since the reinforcing plates 7a, 7b are used to limit the first turning range Therefore, the first rotation range can be sufficiently restricted by only the first biaxial hinge 1, and therefore, the bracket 1 and the display device 12 or the support bracket 40 may not be provided on the bracket for limiting the first rotation range. With the unit, the size of the bracket such as the support bracket 40 can be reduced, and as a result, the size of the first biaxial hinge 1 can be reduced.

Further, the second rotation range restricting unit 9 is formed such that the second rotation range restricting convex portion 91 is provided on the outer circumference of the flange portion 6a of the second shaft 6, and the second rotational range restricting convex portion 91 is overlapped (engaged). The second rotation range restricting protrusion 92 provided on the second reinforcing plate 7b, so that the portion where the second rotation range restricting convex portion 91 overlaps when the second rotation range is restricted is the second rotation range of the reinforcing plate 7b The restricting projection 92 is not directly associated with the bracket such as the support bracket 40. Therefore, a unit for restricting the second rotation range can be provided not on the bracket such as the support bracket 40, and the bracket supporting the bracket 40 or the like can be realized. As a result of miniaturization, the miniaturization of the first biaxial hinge 1 can be further achieved.

Further, by using the compression spring as the second biasing means 66, the outer diameter of the portion of the portion connecting the support bracket 40 and the mounting bracket 31, that is, the outer diameter of the sleeve 67 can be reduced, and when the disc spring is used as the second application In the case of the force unit 66, if the outer diameter of the disc spring is reduced, the outer diameter of the disc spring cannot be flexed, and the function cannot be performed as a spring. Therefore, the outer diameter of the connecting portion where the support bracket 40 and the mounting bracket 31 are connected becomes large, and the result is changed. In contrast, the compression spring has a function as a spring even if the outer diameter is reduced, and the adjustment of the urging force is easy. Therefore, by using the compression spring as the second urging unit 66, the support bracket 40 and the support bracket 40 can be reduced. Mounting bracket 31 is connected The outer diameter of the portion is the outer diameter of the sleeve 67. As a result, the overall size of the first biaxial hinge 1 can be reduced. Moreover, by using the disc spring as the first biasing unit 83, the second base holder can be shortened. The length of the portion of the frame 22 that is connected to the support bracket 40, that is, the length of the sleeve 84, results in miniaturization of the first biaxial hinge 1.

Further, a lead wire for electrically connecting the device body 11 and the display device 12, for example, the FPC passes through the inside of the first A-axis 51 and reaches between the holder portions 42a and 42b of the support bracket 40, and passes through the inside of the second shaft 6 from there. The wiring can be easily performed.

6a to 7d are schematic views of an electronic device of a second biaxial hinge according to the present invention; and Figs. 8 to 10 are schematic views of a second biaxial hinge according to the present invention; The second biaxial hinge is different from the first biaxial hinge 1 as described above in that the structure of the second rotation range restricting unit 9 and the first rotational range limited by the first rotational range limiting unit 70 are based on The control of the first rotation control unit 8 and the control by the second rotation control unit 60 are the same as those of the first biaxial hinge 1 described above, and the description thereof will be omitted.

Referring to FIGS. 6a to 7d, the second biaxial hinge 100 is also used for opening and closing the electronic device 14 as an example of the electronic device 14 having the second biaxial hinge 100, and is portable.

The two reinforcing plates 7f and 7g have a substantially rectangular flat plate shape, and are formed, for example, as a reinforcing plate 7g (sometimes referred to as a third reinforcing plate) having one end portion in contact with the inner surfaces of the bracket portions 42a and 42b and on the second bracket portion 42b side. The other end portion is located near the insertion hole 43 of the support plate portion 41.

The substantially parallel U-shape is substantially in a sliding contact with the surfaces of the two reinforcing plates 7f and 7g, and the first flat portion 73a of the first A-turning range restricting portion 73 is in contact with the surfaces of the reinforcing plates 7f and 7g. The first rotation angle of the second flat portion 73b of the first AA rotation range restricting portion 73 in contact with the surfaces of the reinforcing plates 7f and 7g is -15 to 165, whereby when the first rotation angle is 0° The second frame body 16 is in close contact with the first frame body 15, and the second frame body 16 is not further rotated in the negative direction with respect to the first frame body 15, so that the first rotation range is limited to 0° to 165°; Further, in the present invention, -15° includes approximately -15° and 165° includes approximately 165°.

The compression spring 88 is used as the first urging unit constituting the first rotation control unit 8, and the first cam recess constituting the first rotation control unit 8 is provided with four, two first A cams on the first cam body 82. The recesses 89a are disposed at intervals of 180° in the circumferential direction of the first cam body 82, and the remaining two first B cam recesses 89b are disposed at intervals of 180° in the circumferential direction of the first cam body 82, and are disposed at the same position as the first cam The recessed portion 89a is spaced apart from the circumferential direction by 100°, and the first A cam recessed portion 89a is formed such that the first rotational angle is completely engaged with the first cam convex portion 87 when the first rotational angle is from 0°, for example, −10°, and when formed as such When the first rotation angle is 0° and 165°, the first cam convex portion 87 is not completely engaged with the first A cam concave portion 89a but is in the middle of engagement, and the first cam convex portion 87 is located at the first A cam concave portion 89a. Slant In the middle of the surface, the first B cam recess 89b is formed at a position that engages with the first cam lobe 87 when the first rotation angle is 90°, and the first cam recess 89a and the first B of the first cam body 82. The surface other than the cam recess 89b is formed as a flat surface, and when the front end portion of the first cam convex portion 87 is in contact with the plane, for example, when the first rotation range is 10° to 80° and 100° to 150°, friction occurs. In addition, the first rotation range in which the free stop state is formed is not limited to 10 to 80 degrees and 100 to 150 degrees, and the shape of the first A cam recess 89a and the first B cam recess 89b can be changed. Set to the desired angle.

The 2A rotation range restricting portion 93 constituting the second rotation range restricting unit 9 is formed, for example, such that the outer circumference of the flange portion 6a of the second shaft 6 is formed in a substantially U shape and is in sliding contact with the side surface of the third reinforcing plate 7g. The U-shaped first first flat portion 93a and the second flat portion 93b of the second A-rotational range restricting portion 93 are formed substantially parallel to each other, and the second B-rotational range restricting portion is the third reinforcing plate 7g. The range in which the two housings 16 are rotated about the second shaft 6 with respect to the first housing 15 is limited to a state in which one of the first flat portions 93a of the second A rotation range restricting portion 93 is in contact with the side surface of the reinforcing plate 7g. The second rotation range limiting unit is used until the second second flat portion 93b of the second AA rotation range restricting portion 93 is in contact with the side surface of the third reinforcing plate 7g in the second rotation range of 0° to 180°. The second rotation range is limited to the range of 0° to 180°, but is not limited thereto. For example, the two first plane portions 93a and the second plane of the 2A rotation range restriction portion 93 may be changed. The relative angle of the portion 93b is limited to an arbitrary range.

The second cam convex portion 68 and the second cam concave portion 69 constituting the second rotation restricting unit 60 are respectively provided on the second cam body 63 and the second cam portion 62 at intervals of 180° in the circumferential direction, for example, two of the second The cam lobe 68 and the second cam recess 69 are formed when the second frame 16 rotates within a second rotation range of 0° to 180° with respect to the first frame 15, when the second rotation angle is 0° and At 180°, the second frame 16 is held at the position with respect to the first frame 15, and, for example, friction is generated in a second rotation range of 10 to 170° to be in a free stop state, that is, the second cam protrusion 68 is formed in a substantially trapezoidal shape in cross section, and cam faces 62a other than the second cam recesses 69 of the second cam portion 62 are formed in a plane, and the cam faces of the second cam portions 68 and the cam faces of the second cam portions 62 are formed. 62a is in surface contact with each other in a second rotation range of 10° to 170° to generate friction, thereby becoming a free stop state; and the second rotation range forming the free stop state is not limited to 10° to 170°, and can be changed. The shape or the like of the second cam recess 69 is set to a desired angle.

Next, the action of the second biaxial hinge 100 and the electronic device 14 according to the present invention will be described.

In a closed state in which the first frame body 15 and the second frame body 16 are overlapped with each other, for example, the surface of the first frame body 15 having the operation portion 17, that is, the surface of the second frame body 16 having the display portion 18 is closely attached. In the state of being in the closed state, the first rotation angle is 0°, and the first cam convex portion 87 and the first A cam concave portion 89a are engaged by the elastic force of the compression spring 88, and the second rotation angle is 0°. The second cam protrusion 68 is engaged with the second cam recess 69 by the elastic force of the compression spring (ie, the aforementioned second force applying unit 66), and thus, The first frame body 15 and the second frame body 16 are kept in a closed state (see Fig. 6a).

In the closed state, the first cam convex portion 87 is engaged with the first A cam concave portion 89a, but the engagement is not complete (including substantially completely) fitting, but the front end portion of the first cam convex portion 87. Since the first frame body 15 and the second frame body 16 are biased by the elastic force of the compression spring 88 so as to be in the middle of the inclined surface of the first A cam recessed portion 89a, the first frame body 15 and the second frame are placed. The body 16 remains closed in a swaying manner.

In order to open the second housing 16 to use the electronic device 14 in the closed state, for example, the second housing 16 is opened in the axial direction with respect to the first housing 15 with the first A-axis 51 and the first B-axis 52 (second The frame 16 is rotated in the direction in which the first frame body 15 is separated. At this time, the state in which the first flat portion 73a of the first A-turning range restricting portion 73 approaches the surfaces of the reinforcing plates 7f and 7g becomes the first A-turning range restricting portion 73. The semicircular portion 73c is in sliding contact with the surfaces of the reinforcing plates 7f and 7g, and further, when the second frame body 16 is rotated by 90° with respect to the first frame body 15 (see FIGS. 6b and 6c), the first cam convex portion 87 is engaged with the first B cam recess 89b, so that the second housing 16 is held at the first A open state of 90° with respect to the first housing 15, and in the first A open state, the operation portion 17 is operable. Since the display unit 18 is exposed and visually exposed, the operation unit 17 can be operated while viewing the display unit 18.

Further, when the second housing 16 is rotated from the first A-open state to the first housing 15, the first rotation angle is 165° (see FIG. 6d, 6E), the second flat portion 73b of the first AA rotation range restricting portion 73 comes into contact with the surfaces of the reinforcing plates 7f and 7g, and the rotation is stopped, and the first cam convex portion 87 is engaged with the first A cam concave portion 89a. The one frame 15 and the second frame 16 are held in the second open state, and in the second open state, the operation unit 17 can be operated while observing the display unit 18.

In the second open state, the first cam convex portion 87 is engaged with the first A cam recess portion 89a, but the card merge is not a complete (including substantially complete) fitting state, but the front end of the first cam convex portion 87. The portion is located in the middle of the inclined surface of the first A cam recess 89a. Therefore, the first frame 15 and the second frame 16 are superposed by the elastic force of the compression spring 88, so that the first frame 15 and the second frame 15 The frame 16 is kept in the second open state without shaking.

Further, when the second housing 16 is rotated about the first A-axis 51 and the first B-axis 52 with respect to the first housing 15, the first rotation angle is in the range of 10° to 80° and 100° to 150°. When the first cam convex portion 87 is separated from the first A cam concave portion 89a or the first B cam concave portion 89b, the front end portion of the first cam convex portion 87 slides on the surface while being in contact with the plane of the first cam body 82. Therefore, a friction torque is generated between the first frame body 15 and the second frame body 16, so that when the rotation of the second frame body 16 is stopped, the second frame body 16 is stopped at the position by the friction torque. Therefore, the second frame body 16 can be stopped at a desired position in the first rotation range of 10° to 80° and 100° to 150° with respect to the first frame body 15.

When returning from the second open state and the first open state to the closed state, the second frame 16 is made to be the first A-axis 51 and the first B-axis with respect to the first frame 15 The rotation of the shaft 52 in the closing direction (the direction in which the first housing 15 approaches the second housing 16) returns to the closed state in which the first housing 15 and the second housing 16 overlap each other.

When the second housing 16 is rotated about the first A-axis 51 and the first B-axis 52 with respect to the first housing 15, the second housing 16 is in the first A-open state, for example, the second A-rotation range limiting unit 93. Since the first flat portion 93a is in contact with the side surface of the third reinforcing plate 7g, it is possible to rotate in a direction in which the semicircular portion 93c of the second A-turning range restricting portion 93 can contact the side surface of the third reinforcing plate 7g. The second housing 16 is rotated from the first A-open state with respect to the first housing 15 by the second shaft 6, and the rotation can be performed on the second flat portion 93b and the third reinforcing plate up to the 2A rotation range restricting portion 93. 7g is performed in the second rotation range of 0° to 180° until the side surface contacts, and becomes an intermediate state when rotated by 90° (refer to FIGS. 7a and 7b), and becomes a second frame when rotated further by 90°. The first B open state in which the orientation of 16 is different from the first open state (see FIGS. 7c and 7d). At this time, since the second cam convex portion 68 is engaged with the second cam concave portion 69, the first frame can be The body 15 and the second frame 16 are kept in the first B open state.

Further, when the second frame body 16 is rotated about the second shaft 6 with respect to the first frame body 15, when the second rotation range is 10 to 170 degrees, the second cam convex portion 68 is from the second cam concave portion. 69 is disengaged, and the protruding surface 68a of the second cam convex portion 68 is in surface contact with the cam surface 62a of the second cam portion 62 while sliding on the surface, thereby being between the first frame body 15 and the second frame body 16. The friction torque is generated, so when the rotation of the second frame 16 is stopped, the second frame Since the frictional torque can be stopped at this position, the second housing 16 can be stopped at a desired angle in the second rotation range of 10 to 170 with respect to the first housing 15.

Further, in the first B open state, the second housing 16 can be rotated in the closing direction with the first A-axis 51 and the first B-axis 52 as the axes with respect to the first housing 15, so that the display unit 18 can be formed. The closed state of the surface. In this case, the display unit 18 can be observed while the second housing 16 is closed.

Therefore, for example, in a state in which the first frame body 15 is held by one hand and fixed, the second frame body 16 is grasped by the other hand, and the second frame body 16 is opposed to the first frame body 15 by The first A-axis 51 and the first B-axis 52 are pivoted and opened, and the second housing 16 is rotated about the second shaft 6 with respect to the first housing 15 , whereby the angle of the second housing 16 can be performed. Adjustment, the second frame 16 can be easily adjusted to a position that is easy to see.

In this manner, when the second housing 16 is rotated about the first A-axis 51 and the first B-axis 52 with respect to the first housing 15, the second housing 16 is second with respect to the first housing 15 When the shaft 6 is rotated, particularly when the second frame body 16 is rotated about the second shaft 6 with respect to the first frame body 15, the second shaft 6 for the second rotation mechanism acts on the support plate portion 41. The force to be released from the support plate portion 41 of the support bracket 40, that is, the tensile load acts on the support plate portion 41, so that the both side portions of the support plate portion 41 are to be bent toward each other, but Since the reinforcing plates 7f and 7g are attached to the inner surface of the support plate 41, the support plate portion 41 is not bent. Therefore, the thickness of the support plate portion 41 can be shortened, so that the length of the support bracket 40 can be shortened, that is, When the thickness of the support plate portion 41 is increased, since the support bracket 40 is formed by bending both end portions of the substrate, the thickness of the bracket portions 42a and 42b is also increased, and the length of the support bracket 40 is lengthened, but By attaching the reinforcing plates 7f and 7g to the inner surface of the support plate portion 41, the thickness of the bracket portions 42a and 42b is not increased. Therefore, the length of the support bracket 40 can be shortened, so that the number of components can be reduced to achieve cost reduction. In addition, it is possible to ensure the required strength of the support plate portion 41 and to reduce the size of the support bracket 40. As a result, the size of the second biaxial hinge 100 can be reduced.

Further, the first rotation range restricting unit 70 is formed such that the first A rotation range restricting portion 73 is provided on the outer periphery of the flange portion 51a of the first A-axis 51 and the flange portion 52a of the first B-axis 52, and the first A-turn range is set. The restricting portions 73 are in sliding contact with the surfaces of the two reinforcing plates 7f and 7g, respectively, and the portions that engage with the first A-turning range restricting portion 73 when the first rotational range is restricted are the reinforcing plates 7f and 7g, and are not directly connected to the supporting bracket. 40 or the like is associated with the bracket; that is, the flange portions 51a and 52a of the two first A-axis 51 and the first B-axis 52 are used as stoppers, and the two stoppers are respectively transmitted to the reinforcing plate 7f, 7 g of surface sliding contact (engagement) can increase the surface for limiting the first range of rotation, and since the reinforcing plates 7f, 7g are used to limit the first range of rotation, only the second biaxial hinge 100 can be used Since the first rotation range is sufficiently restricted, the unit for restricting the first rotation range may not be provided on the brackets of the first housing 15 and the second housing 16, or the support bracket 40, so that the support bracket can be realized. Miniaturization of 40 brackets, as a result of which a second biaxial hinge can be realized The miniaturization of 100.

And, the second rotation range restricting unit 9 is formed to rotate the 2A The range restricting portion 93 is provided on the outer circumference of the flange portion 6a of the second shaft 6, and the second A-rotation range restricting portion 93 is overlapped (engaged) on the side surface of the third reinforcing plate 7g, thereby restricting the second rotation range. The portion where the 2A rotation range restricting portion 93 overlaps is the third reinforcing plate 7g, and is not directly associated with the bracket such as the support bracket 40. Therefore, it is not necessary to provide a second rotation for the bracket such as the support bracket 40. The unit of the range can reduce the size of the bracket such as the support bracket 40, and as a result, the size of the second biaxial hinge 100 can be further reduced.

Further, by using the compression spring 66 as the second biasing means, it is possible to reduce the outer diameter of the sleeve 67 which is the outer diameter of the portion where the support bracket 40 is connected to the mounting bracket 31, that is, when the disc spring is used as the first In the case of the second force applying unit, if the outer diameter of the disc spring is reduced, the outer diameter of the disc spring cannot be flexed, and the function cannot be performed as a spring. Therefore, the outer diameter of the connecting portion where the support bracket 40 and the mounting bracket 31 are connected becomes large, and as a result, In contrast, the compression spring (that is, the second urging unit 66) has a function as a spring even if the outer diameter is reduced, and the adjustment of the urging force is easy. Therefore, the compression spring is used as the second urging force. The unit 66 can reduce the outer diameter of the sleeve 67 that connects the support bracket 40 and the mounting bracket 31, and as a result, the overall size of the second biaxial hinge 100 can be reduced and transmitted. As the first biasing means, the compression spring 88 can reduce the outer diameter of the portion of the portion where the second base bracket 22 and the support bracket 40 are connected, that is, the outer diameter of the sleeve 84. As a result, the second biaxial hinge 100 can be realized. miniaturization.

And a wire for electrically connecting the first frame 15 and the second frame 16 For example, the FPC passes between the bracket portions 42a and 42b of the support bracket 40 through the inside of the first A-axis 51, and passes through the inside of the second shaft 6 from there, so that the wiring can be easily performed.

In the biaxial hinge according to the present invention described above, since the reinforcing plate for reinforcing the bending strength of the supporting plate portion is attached to the supporting plate portion of the supporting member, the number of components can be reduced, the cost can be reduced, and the support can be ensured. The necessary strength of the plate portion is achieved and miniaturization, and since the first rotation range restricting unit is disposed between the base member and the support member, the first rotation range restricting unit is limited by the 1A rotation range provided on the first shaft And a reinforcing plate attached to the support member, the reinforcing plate engaging with the first A-rotational range restricting portion to restrict a first rotation range of the support member relative to the base member, thereby sufficiently limiting the first rotation range In particular, it is preferable as a component used in a camera device such as a video camera, a digital camera, and a portable mobile phone.

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 in the field of the present invention are known to those skilled in the art.
