It is possible to maintain the arrangement state after the first slide movement is completed without.

On the other hand, Figure 9 is a slide hinge device according to the present invention, a perspective view for explaining a state in which the second slide hinge opening slide.

As shown in FIG. 9, since the first and second actuators 340 and 350 are disposed on the inner surface of the second slide hinge 320, the first and second actuators 340 and 350 in the open state of the slide 200. ) Can be concealed without being exposed to the outside.

On the contrary, after the personal portable terminal is used, the slide unit 200 may be closed in the opposite direction as when the portable terminal is opened, and the slide unit 200 may be returned to its initial state before the slide unit 200 is opened. Even when the slide unit 200 is closed, the second slide hinge unit 320 may sequentially move the first slide and the second slide in the same manner as when the slide unit 200 is opened. The first actuator portion 340 having a relatively small elastic force among the first and second actuator portions 340 and 350 connected in series via the branch portion 330 is operated first, and the first slide portion 320 of the first slide portion 320 is operated. The slide movement may be elastically supported, and the second slide movement of the second slide hinge portion 320 may be elastically supported by the second actuator portion 350.
