Next, a case where the hinge device A of the present invention is used as the opening device of the notebook computer 1 will be described.

Usually, in the unused state of the notebook computer, the first casing 2 and the second casing 3 are overlapped with each other to be in a closed state (0°). At this time, as shown in FIGS. 7 to 10, the bottom plate 6a and the assembly plate 6i of the assembly element 6 are assembled to the assembly portion 2c by the assembly screws 16a and 16b, and are attached to the concave portion on the rear portion of the first casing 2.

Further, the second casing 3 is assembled to the support member 11 by the assembly holes 11i, 11i, 11i and the support piece 11b provided on the first support substrate 11a. As shown in FIG. 7, when the first housing 2 and the second housing 3 are in a closed state in which they are closed to each other, the top portion 7a of the cam slider 7 and the cam convex portion 10a of the pop-up cam member 10 are in a crimped state. When the pop-up cam member 10 is pressed in the clockwise direction, the rotational torque is transmitted to the support member 11 by the rotation transmitting member 12, and the second housing 3 is pushed toward the first casing 2 side by the support member 11. The first housing 2 and the second housing 3 are overlapped and held in a closed state. Further, as shown in Fig. 11(a), in the closed state, the outer cam portions 21e and 23d and the inner cam portion of the cam portion 21a and the fixed cam portion 23a are rotated. The inclined portions 21h, 23g, 21h, and 23f of the 21d and 23c are in a pressure contact state with each other, and a plurality of gaps are generated between the outer side cam portions 21e and 23d and the inner side cam portions 21d and 23c.

Accordingly, the first housing 2 and the second housing 3 are maintained in a closed state, and it is not necessary to provide a locking mechanism for locking the first housing 2 and the second housing 3 in the closed state.

When the notebook computer 1 is used, the second casing 3 is manually opened to the first casing 2. First, the closing reinforcing force of the above-described pop-up mechanism 5 and the rotating cam portion 21a of the friction mechanism 20 and The pressure-bonding action of the outer cam portions 21e and 23d of the fixed cam portion 23a generates resistance. When the deployment angle exceeds 15°, as shown in Fig. 11(b), the rotating cam portion 21a of the rotating cam member 21 of the friction mechanism 20 The pressure contact state between the outer cam portion 21e and the outer cam portion 23a of the fixed cam portion 23a of the fixed cam member 23 is relaxed, and the pressure contact state between the outer cam portions 21e and 23d and the inner cam portions 21d and 23c is weakened. Further, as shown in Fig. 8, the cam lobe 10a of the pop-up cam member 10 abuts the cam portion 7b side of the cam slider 7, and the pop-up cam member 10 is rotated counterclockwise, since the rotational torque is rotated The communication element 12 is conveyed to the support element 11, and the second housing 3, which is provided with the support element 11, is automatically bounced, as shown in Fig. 9, and can be deployed, for example, to 60 (also referred to as the bounce angle).

When the second housing 3 is opened to the pop-up angle of the first housing 2, as shown in FIG. 9, the cam slider 7 stops the pressing force on the pop-up cam member 10, and the rotating cam member 21 and the fixed cam of the friction mechanism 20 Turn of component 23 The movable cam portion 21a and the outer cam portion 21e and the outer cam portion 23d of the fixed cam portion 23a are in a crimped state, and then, as shown in Fig. 11(c), the rotational cam member 21 of the friction mechanism 20 and the fixed cam member 23 are rotated. The outer cam portions 21e and 23d of the cam portion 21a and the fixed cam portion 23a and the inner cam portions 21d and 23c are maintained in a pressure-bonded state, and the friction washer 22 is strongly pressed against the first support substrate portion 11a of the support member 11. And the second supporting substrate portion 11c, so that the second housing 3 can be freely stopped relative to the first housing 2 within a range of use angles, as shown in FIG.

Therefore, the notebook computer 1 and the second casing 3 can be freely stopped at an arbitrary angle with respect to the first casing 2 so as to be usable in a stable state.

After the notebook computer 1 is closed, the second housing 3 is closed relative to the first housing 2, firstly, according to the friction torque resistance of the friction mechanism 20, after which the rotating cam member 21 and the fixed cam member 23 of the friction mechanism 20 are closed. The outer cam portions 21e and 23d and the inner cam portions 21d and 23d of the rotating cam portion 21a and the fixed cam portion 23a are released from the pressure contact state, and the friction torque is weak, and is closed by the elastic resistance of the pop-up mechanism 5, since about 15 The bouncing mechanism 5 of the closing angle of °, the pop-up cam member 10 is rotated in the closing direction, so that the rotational torque is transmitted to the supporting member 11 by the rotation transmitting member 12, and the second housing 3 is automatically closed. However, at this time, the inclined portions 21h and 23g of the outer cam portions 21e and 23d of the rotating cam portion 21a and the fixed cam portion 23a are pressed against the inclined portions 21f and 23f of the inner cam portions 21d and 23c, and are relatively buffered by the pop-up mechanism 5 The second housing 3 automatically closes the torque so that the second The housing 3 does not emit a sudden sound when it is closed relative to the first housing 2. Further, since the elastic means 8 uses the compression coil springs 8a, 8b having different sizes, it is possible to feel a softer feeling depending on the action of the pop-up mechanism 5.
