Thereby, the stopping means 19 can limit the position of the first casing 2 and the second casing 3 in the closed state and the position in the fully open state (each opening 180 degrees).

Next, the operation of the above-described hinge device 4 of the present invention will be described. First, when the first housing 2 and the second housing 3 are in the closed state shown in FIG. 1(b), as shown in FIGS. 3 and 15, the first assembled board 11 and the second assembled board 13 are attached. The first cam recess 23b of the first locking cam member 23 is located above, and the outer periphery of the first cam recess 23b abuts against the first cam projection 21a of the locking member 21, as shown in FIG. The second cam recess 24b of the second locking cam member 24 is the second cam projection 21b that is fitted to the locking member 21, so that when the first housing 2 and the second housing 3 are in the closed state, A hinge rod 10 is rotatable, but the second hinge rod 12 cannot be rotated. Thereby, in the closed state of the first casing 2 and the second casing 3, only the second casing 3 can be opened relative to the first casing 2 by the operation of the selective rotation restricting means 15.

Here, if the second housing 3 is opened relative to the first housing 2, since the first hinge lever 10 rotates together, the first cam convex portion 21a above the locking member 21 abuts against the first locking cam. Since the outer periphery of the element 23 is opened, when the second casing 3 is opened, the first casing 2 cannot be rotated together with the second hinge rod 12 by the operation of the selective rotation restricting means 15. Then, if the second housing 3 is continuously opened relative to the first housing 2, the first attraction means 17a has the first A-curved cam projection 30b of the first cam follower 30 and the first B-curved cam projection. The portion 30c initially receives resistance when the first A curved cam recess 20f and the first B curved cam recess 20g of the coupling member 20 are detached, but the first A curved cam projection 30b and the first B curved cam projection 30c. After the first A bending cam recess 20f and the first B bending cam recess 20g are disengaged, the second housing 3 is opened relative to the first housing 2, and the first A friction washer 26 above the first friction torque generating means 16a, A frictional moment will be generated between the second A friction washer 28 and the friction plate 25, which are also located above the first friction torque generating means 16a. Thereby, the second housing 3 can be freely stopped for the first housing 2, and the second housing 3 can be kept in a stopped state with respect to the first housing 2 at an arbitrary opening angle.

Then, if the second housing 3 is continuously opened to the first housing 2, when the opening angle reaches 180 degrees, it can be seen from the content shown in FIG. 16 that the first stopping means 19a is The first stopper piece 23c of the first locking cam member 23 abuts against the first stopping portion 22f of the sliding guiding member 22, so that the rotation of the first hinge rod 10 is restricted, so that the second housing 3 is first When the housing 2 is opened 180 degrees, the operation is stopped. At the same time, as shown in FIG. 16, the first cam recess 23b of the first locking cam member 23 is rotated by 180 degrees to come to the locking member 21. At the position of the first cam convex portion 21a, a gap a is generated therebetween, so that the first casing 2 can be rotated (opened) at this time.

Further, when the second casing 3 is to be opened from the state in which the second casing 3 is opened 180 degrees with respect to the first casing 2, the closing operation can be smoothly performed. In other words, when the second housing 3 is rotated in the closing direction with respect to the first housing 2, the first cam recess 23b of the first locking cam member 23 and the locking member 21 are rotated by the first hinge lever 10 A gap a is formed between the cam projections 21a, so that the second housing 3 can be closed with respect to the first housing 2. Once the second housing 3 is rotated in the closing direction with respect to the first housing 2, the outer peripheral edge thereof will abut against the first cam convex portion 21a, at which time the second cam convex portion 21b of the locking member 21 will be fixed to The second cam recess 24b of the second lock cam member 24 of the second hinge lever 12 is in a fitted state, and therefore, the rotation of the first housing 2 is also restricted when the second housing 3 performs the closing operation.

Thereby, the second housing 3 can freely open the opening relative to the first housing 2 within an angular range of 0 to 180 degrees, and at the same time, by the selective rotation limiting means 15 In operation, the rotational motion of the first housing 2 will be limited.

Next, when the first housing 2 and the second housing 3 are in the closed state shown in FIG. 1(b), as described above, since the outer peripheral edge of the first locking cam member 23 abuts against the locking member 21 The first cam convex portion 21a does not perform the opening operation of the first casing 2. However, after the second housing 3 is opened 180 degrees, the first housing 2 can be rotated 180 degrees in the opposite direction to the opened second housing 3. In other words, after the second housing 3 is rotated by 180 degrees, as shown in FIG. 16, the first cam recess 23b of the first locking cam member 23 is rotated by 180 degrees to face the first cam projection 21a of the locking member 21, both A gap a will be created between, and therefore, the second locking cam member 24 assembled by the second hinge lever 12 to restrict rotation will be able to rotate at this time. When the first housing 2 starts to rotate, the outer peripheral edge of the second locking cam member 24 will abut against the second cam projection 21b of the locking member 21, so that the second housing 3 will not be able to perform the closing operation.

Here, if the first housing 2 is rotated relative to the second housing 3 in the opposite opening direction from the second housing 3, the second hinge rod 12 will rotate together, so that the second member below the locking member 21 The cam convex portion 21b abuts against the outer peripheral edge of the second lock cam member 24, and therefore, the second housing 3 cannot be rotated in the closing direction by the operation of the selective rotation restricting means 15. Then, if the first housing 2 is continuously rotated relative to the second housing 3, the second attraction means 17b is bent by the second A-curved cam projection 31b of the second cam follower 31 and the second B The cam convex portion 31c initially receives the resistance while disengaging the second A bending cam recess 20h and the second B bending cam recess 20i of the coupling member 20, but the second A bending cam projection at the second cam follower 31 After the 31b and the second B bending cam protrusion 31c are separated from the second A bending cam recess 20h and the second B bending cam recess 20i, the first housing 2 is rotated relative to the second housing 3, and the second friction torque generating means 16b Below the second B friction washer 29, the first B friction washer 27, which is also located below the second friction torque generating means 16b, and the friction plate 25 generate a frictional moment. Thereby, the first housing 2 can be freely stopped for the second housing 3, and the first housing 2 can be held in a stopped state with respect to the second housing 3 at an arbitrary rotation (opening) angle.

Then, if the first housing 2 is continuously rotatably stopped in the opening direction opposite to the second housing 3, when the rotation angle reaches 180 degrees, the content shown in FIG. 17 can be It can be seen that the second stopper piece 24c of the second locking cam member 24 in the second stopping means 19b abuts against the second stopping portion 22g of the sliding guiding member 22, so that the rotation of the second hinge lever 12 is restricted. Therefore, the first housing 2 stops the operation after the second housing 3 is opened 180 degrees. In this state, the first housing 2 and the second housing 3 are just in a state of being overlapped with each other.

Further, when the first casing 2 is to be opened from the state in which the first casing 2 is opened 180 degrees with respect to the second casing 3, the closing operation can be smoothly performed. In other words, when the first casing 2 is rotated relative to the second casing 3 from the state shown in FIG. 17 to the closing direction, the outer circumference of the second locking cam member 24 that is rotated together with the second hinge lever 12 is broken. Connected to the second cam convex portion 21b of the locking member 21, and the first cam convex portion 21a of the locking member 21 will be fitted with the first cam concave portion 23b of the first locking cam member 23 fixed to the first hinge lever 10. Therefore, the first housing 2 can be rotated in the direction of its original position. At this time, since the first cam recess 23b of the first lock cam member 23 fixed to the first hinge lever 10 and the first cam projection 21a of the lock member 21 are still in the fitted state, the second housing 3 is opened. The operation is still limited.

Thereby, in a state in which the second casing 3 is opened by 180 degrees, the first casing 2 can freely rotate in an angular range of 0 to 180 degrees with respect to the second casing 3, and at this time, the second casing The opening operation of 3 will be limited due to the operation of the selective rotation restricting means 15. As is apparent from the above description, the first housing 2 and the second housing 3 are selectively opened by the operation of the selective rotation restricting means 15, when the first housing 2 and the second housing 3 are When one of the parties is performing the opening operation, the opening operation of the other side will be restricted.

Then, when the second housing 3 is opened relative to the first housing 2, the touch display operation is performed on the display portion 3a of the second housing 3 with a finger at a specific opening angle within 180 degrees, or in the second housing After the body 3 is opened 180 degrees with respect to the first housing 2, the first housing 2 is further opened 180 degrees in the opposite direction with respect to the second housing 3, and at a specific opening angle on the way, the second pair is also fingered. When the display portion 3a of the casing 3 performs a touch operation, the vibration generated by the display portion 3a can be improved by the operation of the first vibration control means 7 and the second vibration control means 8 of the vibration control means 6, so that no picture is generated. The problem that is difficult to watch does not give the operator a visual fatigue.

In a preferred embodiment, the vibration control means 6 of the present invention is constituted by the first vibration control means 7 and the second vibration control means 8, but only the first vibration control means 7 or the second vibration control means 8 are used. One of the parties can also achieve the above effects. Further, the first vibration control means 7 has its first A vibration control element 7a, the first B vibration control element 7b, a part of the first C vibration control element 7c, and the second vibration control means 8 its second A vibration control element Some of the 8a, the second B vibration control element 8b, and the second C vibration control element 8c may be omitted from the requirements.

Therefore, according to the above description, the hinge device 4 of the present invention can respectively open the first housing 2 and the second housing 3 by 180 degrees through the first hinge rod 10 and the second hinge rod 12, respectively. A total of 360 degrees of opening operation was achieved. However, it should be added that the invention does not limit the opening angle of the first housing 2 and the second housing 3 herein.

In addition, the present invention can not only use the notebook computer 1 in the most basic manner, but also bend the first casing 2 in the same direction with respect to the second casing 3 to roughly display an L-shape or a mountain shape, or The casing 2 and the second casing 3 are stacked to form a flat plate, and the second casing 3 faces the operator and is used as a tablet. In addition, it can be applied to a wide variety of uses.

Further, the first housing 2 can be opened before the second housing 3 by changing the installation positions of the first cam recess 23b and the second cam recess 24b. Further, the absence of the hinge housing 14 does not hinder the operation of the hinge devices 4 and 5, but in the case where the hinge housing 14 is provided, when the hinge devices 4 and 5 are assembled to the information terminal 1, due to the selectivity The rotation restricting means 15, the friction torque generating means 16 and the attraction means 17 are not exposed to the outside, so that they have a relatively simple and sleek appearance.
