And the inner cam portion 23c, the outer cam portion 21e, and the outer cam portion 23d are provided with different positions, respectively, when the rotary cam member 21 rotates, but when the support member 11 rotates, that is, the second one. When the inner cam portions 21d and 23c and the outer cam portions 21e and 23d come into contact with each other when the frame 3 is opened and closed, a strong precushion torque is generated. Incidentally, the inclined portions 21f to 21i and the inclined portions 23e to 23h are provided at both ends of each of the inner cam portions 21d and 23c and the outer cam portions 21e and 23d, respectively.

Next, the operation of the two hinge devices A according to the present invention as an opening and closing device of the notebook 1 will be described.

In a normal state in which the notebook 1 is not used, the first frame 2 and the second frame 3 are in a closed state (0 °) in which they are polymerized with each other. At this time, as shown in FIG. 7 to FIG. 10, the bottom plate 6a of the attaching member 6 is attached to the attaching portion 2c provided as a recess in the upper surface of the rear part of the first frame 2. The mounting plate 6i is mounted using the mounting screws 16a and 16b, and the upper portion thereof is covered by the cover 2b. The support member 11 is provided with mounting holes 11i, 11i and 11i provided in the first support substrate 11a and a second frame 3 using the support piece 11b. As shown in FIG. 7, when the first frame 2 and the second frame 3 are in the closed state closed with each other, the top 7a and the pop-up of the cam slider 7 are closed. Since the cam part 10a of the cam member 10 is in a press-contact state and the pop-up cam member 10 is pressed in the clockwise direction, the rotational torque thereof is supported by the rotation transfer member 12. And the second frame 3 is pressed against the first frame 2 side by using the supporting member 11, so that the first frame 2 and the second frame 3 ) And are kept closed. In this closed state, as shown in Fig. 11A, the inclined portions 21h and 23g of the outer cam portions 21e and 23d and the inner cam portions 21d and 23c of the rotary cam portion 21a and the fixed cam portion 23a, and The inclined portions 21h and 23f are in pressure contact with each other, and a slight gap is formed between each outer cam portion 21e and the outer cam portion 23d and the inner cam portions 21d and 23c.

Thus, the lock mechanism for locking the 1st frame 2 and the 2nd frame 3 to the closed state by maintaining the closed state of the 1st frame 2 and the 2nd frame 3 is performed. It can be unnecessary.

In the case of using the notebook 1, when the second frame 3 is manually opened with respect to the first frame 2, the closing force of the pop-up mechanism 5 described above is first applied. Although the resistance due to the pressure contact action of the rotating cam portion 21a of the precushion mechanism 20, the outer cam portion 21e of the fixed cam portion 23a, and the outer cam portion 23d is met, the opening angle of about 15º is exceeded. As shown in 11 (b), the outer cam portion 21e of the rotary cam portion 21a of the rotary cam member 21 of the precushion mechanism 20 and the outer cam portion of the fixed cam portion 23a of the fixed cam member 23 ( The contact state between 23d) is relaxed and the contact state of each of the outer cam portions 21e and 23d and the inner cam portions 21d and 23c is weakened. Furthermore, as shown in FIG. 8, the pop-up cam member 10 is shown. Since the cam part 10a of the cam contact part comes into contact with the cam part 7b side of the cam slider 7, the pop-up cam member 10 exerts a force which rotates counterclockwise. Rotating torque Since the second frame 3 attached to the support member 11 is automatically popped up by using the rotational transmission member 12 to the support member 11, it is shown in FIG. For example, it opens up to 60º (also called the pop-up angle).

When the second frame 3 is opened with respect to the first frame 2 up to this pop-up angle, as shown in FIG. 9, the pop-up cam member (by the cam slider 7) 10, the pressing force to the stop is stopped, the rotary cam member 21 of the precushion mechanism 20, the rotary cam portion 21a of the fixed cam member 23 and the outer cam portion 21e and the outer cam portion of the fixed cam portion 23a. 23d is in a pressure contact state, and then, as shown in FIG. 11C, the rotary cam member 21 of the precushion mechanism 20, the rotary cam portion 21a of the fixed cam member 23, and the fixed cam portion 23a. The outer cam portions 21e and 23d and the inner cam portions 21d and 23c of the < RTI ID = 0.0 >) < / RTI > Since the pressure contact between the board | substrate part 11c is stronger, the 2nd frame 3 will be able to stop freely with respect to the 1st frame 2 in the use angle range. This state is shown in FIG.

Accordingly, the notebook computer 1 can stop the second frame 3 at any angle capable of stopping freely with respect to the first frame 2 and can be used in a stable holding state.

After using the notebook 1, when the second frame 3 is closed with respect to the first frame 2, it is first closed by encountering resistance by the precushion torque of the precushion mechanism 20 and thereafter. The rotating cam member 21 of the precushion mechanism 20, the rotating cam portion 21a of the fixed cam member 23, and the outer cam portions 21e and 23d and the inner cam portions 21d and 23c of the fixed cam portion 23a are provided. The relatively weak pretorque and the elastic resistance of the pop-up mechanism 5 are closed from being released from the pressure contact state, and the pop-up mechanism 5 pops up from a closing angle of about 15º. This rotation torque is transmitted to the support member 11 using the rotational transmission member 12 so that the cam frame 10 is applied to the cam member 10 in the closing direction, so that the second frame 3 automatically It is closed. However, at this time, the inclined portions 21h and 23g of the outer cam portions 21e and 23d of the rotary cam portion 21a and the fixed cam portion 23a and the inclined portions 21f and 23f of the inner cam portions 21d and 23c are press-contacted. In this case, the pop-up mechanism 5 causes the automatic closing torque for the second frame 3 to be cushioned so that the second frame 3 makes a sound with respect to the first frame 2. There is no sudden closure. In addition, since the elastic means 8 uses compression coil springs 8a and 8b having different diameters, it is possible to make the operation of the pop-up mechanism 5 feel soft.

Fig. 14 shows another embodiment of the hinge device according to the present invention, and the hinge device B according to the second embodiment has the hinge device A of the first embodiment except for the cam slider in terms of its constituent members. ) Therefore, the same members as those of the hinge apparatus A of the first embodiment are denoted by the same reference numerals except for the pop-up cam member. The cam slider 32 of the hinge device B of the second embodiment differs from the cam slider 7 of the first embodiment in terms of the width of the government. The width of the top portion 32a of the cam slider 32 of the second embodiment is wider than the width n of the cam slider 7 of the first embodiment and has a relationship of n <n.

 Therefore, when the hinge device A of the first embodiment and the hinge device B of the second embodiment are used as the opening and closing device of the notebook computer 1, the first frame 2 of the second frame 3 is opened. At first, the cam portion 10a of the pop-up cam member 10 of the hinge device A is deflected from the top portion 7a of the cam slider 7, and then the hinge device ( The cam part 31a of the pop-up cam member 31 of the pop-up mechanism 30 of B) falls from the top part 32a of the cam slider 32. As shown in FIG. . For this reason, the pop-up mechanisms 5 and 30 of the hinge device A and the hinge device B are compared with that of the pair of hinge devices A and A simultaneously pop-up operation.

Next, as another embodiment of changing the start time of the pop-up operation of the hinge device A and the hinge device B, each pop-up of the hinge device A and the hinge device B is performed. The position of the circumferential direction to be attached to the cam member 10 and the pop-up 31 hinge shaft 9 may be changed. Even in this case, the timing at which the cam portions 10a and 31a of the pop-up cam members 10 and 31 fall from the top portions 7a and 32a of the cam sliders 7 and 32 is changed.
