First, the first friction torque generating mechanism C1 further comprises a first friction torque generating section C1-1 and a second friction torque generating section C1-2. The first friction torque generating portion C1-1 is provided on the side of the first C hinge shaft 12, and is in contact with a first tightening screw 72 provided substantially in the center of the first C hinge shaft 12, and is in turn connected to a first friction washer 73. , a plurality of disk springs 74, a second friction washer 75, a seventh connecting member 51, a third friction washer 76, an eighth connecting member 52, and a fourth friction washer 77 in this order.

Therefore, when the first housing 2 and the second housing 3 are opened and closed, the first friction torque generating section C1-1 and the second friction torque generating section C1-1 of the first friction torque generating mechanism C1 and the second friction torque generating mechanism C2 Friction torque is generated in the generating portion C1-2, the third friction torque generating portion C2-1, and the fourth friction torque generating portion C2-2.

Next, the operation of the opening/closing device 4 will be described. A user can hold the terminal device 1 and open either or both of the first housing 2 and the second housing 3 . In this case, for example, when the first housing 2 side is held with one hand and the second housing 3 side is opened with the other hand, through the opening operation, the 1B mounting member 18 of the synchronous rotation mechanism A is attached. Since the first A hinge shaft 10 rotates, this rotational driving force is transmitted to the second A hinge shaft 13 via the first synchronous rotational drive first belt 28 and the first synchronous rotational drive second belt 29, and this rotational drive Since the force causes the second mounting base 8 to rotate in the opposite direction to the first mounting base 7, the first housing 2 is positioned in the opposite direction to the second housing 3 via the first B mounting member 18 and the second B mounting member 19. It will open in the direction Then, as the first mounting base 7 and the second mounting base 8 are opened and closed, the first C hinge shaft 12 rotates via the first D mounting member 22, and at the same time, the second C hinge shaft 15 rotates via the second D mounting member 23. will rotate. At the same time, the 1B hinge shaft 11 rotates through the first connecting cylinder portion 61 and the 2B hinge shaft 14 rotates through the second connecting cylinder portion 63 . Then, the first slide mechanism B1 and the second slide mechanism B2 of the slide mechanism B and the first friction torque generation mechanism C1 and the second friction torque generation mechanism C2 of the friction torque generation mechanism C operate simultaneously via the synchronous rotation mechanism A. will do.

The above operation also occurs when the first housing 2 and the second housing 3 are closed, simply by reversing the movements. In the above operation, even if the first housing 2 is mainly operated, and even if the first housing 2 and the second housing 3 are operated simultaneously, the synchronous rotation mechanism A operates and rotates. Since the driving force is transmitted to the 1st A hinge shaft 10 and the 2nd A hinge shaft 13, the 1st B hinge shaft 11 and the 2nd B hinge shaft 14, and the 1st C hinge shaft 12 and the 2nd C hinge shaft 15 rotate simultaneously. the same will occur.

Alternatively, according to the present invention, the slide mechanism B operates without using the synchronous rotation mechanism A. Furthermore, with the friction torque generating mechanism C, when the first housing 2 and the second housing 3 are opened and closed, the first housing 2 and the second housing 3 can be stably stopped and held in a free stop. The slide mechanism B operates without this.

Next, the operation of the slide mechanism B will be described. The first slide mechanism B1 and the second slide mechanism B2, which constitute the slide mechanism B, operate synchronously via the synchronous rotation mechanism A so that both the first B hinge shaft 11 and the second B hinge shaft 14 move in opposite directions. Due to the rotation, the first slide member 34 and the second slide member 35 are driven in opposite directions by the first slide mechanism drive belt 30 and the second slide mechanism drive belt 31, respectively, and the third slide mechanism drive belt 32 and the fourth slide member 35 are driven in opposite directions. The slide mechanism drive belt 33 causes the third slide member 36 and the fourth slide member 37 to slide in opposite directions. At this time, even if each of the first slide mechanism drive belt 30 to the fourth slide mechanism drive belt 33 is made of a thin metal material, the first links of the first link mechanism B3 and the second link mechanism B4 can be used. The member 70 and the second link member 71 assist the operation of any one of the first slide mechanism drive belt 30 to the fourth slide mechanism drive belt 34 on the side to be rewound, and are connected to this rewound slide mechanism drive belt. Also, by assisting the operation of any one of the first slide member 34 to the fourth slide member 37, deflection of the belt can be prevented and smooth sliding can be performed.

The engagement shafts 26g and 27g of the short second and fourth operating members 26b and 27b of the first slide mechanism B1 and the second slide mechanism B2 of the slide mechanism B of the opening/closing device 4 are engaged. By the way, the engaging portions 3c provided in the first housing 2 and the second housing 3 shown in FIG. . . (only one shown) slides in the direction away from each other, so that the flexible display sheet 5a stretched over both surfaces of the first housing 2 and the second housing 3 is removed. It is possible to prevent the flexible display sheet 5a from wrinkling due to pulling in the direction.

When the first housing 2 and the second housing 3 are opened and closed, both the first friction torque generating mechanism C1 and the second friction torque generating mechanism C2 of the friction torque generating mechanism C operate to operate as described above. In addition, since friction torque is created, the first housing 2 and the second housing 3 can be stably stopped and held in a free stop at any opening/closing angle, and can provide a comfortable operation feeling.

The opening/closing angle of the opening/closing device 4 of Embodiment 1 is between 0° and 180°. When the mounting piece 45d of the first connecting member 45 connecting the shaft 10 and the second A hinge shaft 13 and the engaging stepped portions 16e and 17e provided on the first A mounting member 16 and the second A mounting member 17 come into contact with each other, , is prevented from being opened any further.
