Next, the operation and effect of the above-described opening device 4 of the present invention will be described. Further, the following description is not fully shown, and the first assembly member 8 and the second assembly member 10 of the opening device 4 are assembled to the first casing 2. In the rear portion, the support member 12 of the opening device is assembled to the rear portion of the second casing 3 for explanation.

First, in the normal state, if the first housing 2 and the second housing 3 are relatively opened by the opening device 4, the partial rotation of the tilting shaft 6 of the opening device 4 causes the second housing 3 to be rubbed. The friction function of the mechanism 11 can be arbitrarily stopped at any opening position relative to the first housing 2. Even if the hand is released at an arbitrary opening angle, there is no fear that the second casing 3 naturally falls relative to the first casing 2. The user can view the keyboard portion 2a of the first casing 2 in an open state in which the second casing 3 is opened at an arbitrary opening angle with respect to the first casing 2, and the notebook computer 1 is used.

Under normal use, the friction function of the tilting shaft 6 does not cause any hindrance. However, in the case where the finger touch operation is performed on the display screen of the display portion 3a of the second casing 3, the second casing 3 is pressed backward by the touch operation, and when the touch operation is repeated, the The stop holding ability of the friction mechanism 11 causes the second casing 3 to rotate rearward due to the pressing, and therefore it is necessary to have the stable stopping means 7 of the present invention.

When the second housing 3 reaches the best use angle with respect to the first housing 2, the ON button 23 is depressed, and the swinging member 22 swings in the clockwise direction with the support pin 21 as a fulcrum, and the pressing member 19 is turned to the left. Sliding and crimping with the tapered outer peripheral portion 18a of the tapered member 18 via the tapered bent portion 19a, because the rotation of the rotating shaft 9 can be prevented, and the second casing 3 is tightly fixed to the rotating shaft 9 by the deformation assembling hole 12a. The support member 12 at the end of the fourth deformation shaft portion 9f can prevent the second casing 3 from rotating backward even if the display screen is touched by a finger. Thereby, the operability of the notebook computer 1 can be improved.

When the notebook computer 1 is used, the OFF button 24 is pressed down, and the swinging member 22 swings counterclockwise with the support pin 21 as a fulcrum, and at the same time, the pressing member 19 slides in the right direction, and relaxes via the tapered curved portion 19a of the pressing member 19. For the pressing force of the tapered member 18, the rotating shaft 9 is only acted by the frictional moment of the friction mechanism 11, and the opening operation can be arbitrarily stopped.

Further, when the second casing 3 is closed with respect to the first casing 2, the cam portion 15 is rotated by the cam member 15 together with the shaft 9 and the cam portion 10c of the bearing portion 10a of the second assembly member 10 is closed. With the conventional suction function, the second housing 3 can be locked with respect to the first housing 2 in a closed state.

The locking function of the cam portion 15b of the cam member 15 and the cam portion 10c of the second assembly member 10 can also be utilized at any other opening angle.

Next, although not shown, as another embodiment, the tilting shaft may be configured such that the rotation of the shaft is restricted by the assembly member and is non-rotatable, and the pivoting support member is pivoted, and the support member is non-rotatable. The shaft is used as a rotating portion, and a friction mechanism is provided between the supporting member and the rotating shaft.

In addition, in the embodiment, the friction mechanism is configured such that the assembly component is the first assembly component 8 and the second assembly component 10, and the friction mechanism 11 is mainly disposed on the side of the second assembly component 10, and Restrictively, it is also possible to omit the second assembly element 10 constituting the assembly element, using only the first assembly element 8, and providing a friction mechanism on the side of the first assembly element 8. Further, the steady stop means may have a configuration in which the rotation of the placket is stopped. Furthermore, the cam element can also serve as a stable stop means. Again, press It is also possible that the element has an elastic means to maintain a stable stop state. If necessary, it can be applied to an object that tilts the shaft to stop the movement of the rotating portion.

According to the present invention, in the small electronic device including the first casing 1 provided with the keyboard portion and the second casing provided with the display portion, the pressing provided on the second casing can be operated by finger touch operation. Buttons and display screens, which in turn increase the range of use.
