The first coupling portion 20 is generally in the form of a rectangular plate and is coupled to the first unit 7 of the portable device. A locking portion 21 is provided in the first coupling portion 20 to prevent the second coupling portion 30 from rotating in a closed state. Support members 22 for supporting the first connecting member 50 and the second connecting member 60 are coupled to both sides of the first coupling part 20, respectively. The first connection member 50 and the second connection member 60 are rotatably coupled to each support member 22 one by one. The support member 22 includes a support 24 on which the second connection member 60 is engaged.

The second coupling portion 30 has a generally rectangular plate shape, and guide rails 32 are formed at both sides thereof. Two slide rails 32 are inserted into the slide guides 42, which will be described later, of the slide connecting portion 40 to enable slide movement. The second coupling part 74, which will be described later, of the first elastic force providing part 70 is rotatably coupled to the second coupling part 30. A cover 34 covering the first elastic force providing part 70 is coupled to the second coupling part 30.

The slide connecting portion 40 includes slide guides 42 provided on both sides and support bodies 44 fixed to both sides. The slide rail 32 of the second coupling portion 30 is inserted into the slide guide 42 to enable the slide movement.

The first connector 72 includes an elastic member coupling part 722 to which an elastic member (not shown) is coupled. Since the second connector 74 has the same structure as the first connector 72, a detailed description thereof will be omitted. The second connector 74 includes a second connector 741 and an elastic member coupling part 742. As the two connecting bodies 72 and 74 slide, the connecting portions 721 and 741 of each connecting element 72 and 74 move closer or further away. When the two coupling parts 721 and 741 are close to each other, the two coupling parts 722 and 742 are far from each other. When the two coupling parts 721 and 741 are far from each other, the two coupling parts 722 and 742 are close to each other. The first elastic member (not shown) is a tension spring and is coupled to each elastic member coupling portion 722, 742 of each of the connecting bodies 72, 74. Accordingly, the first elastic member (not shown) exerts a force in a direction of preventing the two elastic member coupling portions 722 and 742 of the connecting members 72 and 74 from being separated from each other.

4 and 5, the operation of the above embodiment will be described in detail.

4 (a) shows that the two units 7 and 9 of the portable device are completely closed, and the first elastic force providing part (70 in FIG. 1) has the second coupling part 30 and the first coupling part 20. The force is applied to move in the direction of the broken line with respect to the dashed line. This allows the two units 7, 9 of the portable device to remain stable in a closed state. At this time, the state of the second elastic force providing unit (80 of Fig. 2) is shown in Fig. 5 (a). Referring to Fig. 5A, the linear member 87 pushes the rotary member 86 to rotate in the direction of the arrow. Therefore, the first connection member 50 rotating together with the rotation member 86 is also forced to rotate in the direction of the arrow shown in solid lines in FIG. In addition, one end of the second coupling portion 30 is caught by the locking portion 21 of the first coupling portion 20. Thus, the two units 7, 9 of the portable device remain stable in the closed state. In order to open the portable device in this state, when the second unit 9 is slid to the first unit 7, the two units 7 and 9 of the portable device are as shown in Fig. 4B. Likewise, it is completely open. At this time, the first elastic force providing unit (70 in Fig. 1) exerts a force to move the second coupling portion 30 in the direction of the broken line with respect to the first coupling portion (20). This allows the two units 7, 9 of the portable device to remain stable in an open state. At this time, the state of the second elastic force providing unit (80 of FIG. 2) continues to maintain the state of FIG. 5 (a), and the rotational force provided to the first connection member 50 is also unchanged. 9) stably maintains the state shown in FIG. In this state, when the second unit 9 is raised with respect to the first unit 7, the rotating member 86 rotates in the opposite direction to the arrow in FIG. Will rotate. At this time, the linear moving member 87 is moved to win the elastic force of the second elastic member (89). When the rotation member 86 rotates about halfway, the direction of the rotation force received by the rotation member 86 is reversed, and the second unit 9 is automatically moved to stand. In FIG. 4C, the state in which the second unit 9 is fully raised with respect to the first unit 7 is shown, and in this case, the state of the second elastic force providing unit 80 is shown in FIG. 5B. It is. The second elastic force providing unit 80 provides a rotational force to the first connection member 50 to stably maintain the state shown in FIG.
