Fig. 5A shows the state of the switching device when the portable device 5 is completely closed, as shown in Fig. 6A. 7A shows the state of the second elastic force providing unit 60 in the state of FIG. 5A. Referring to FIGS. 5A and 7A, since the first elastic force providing unit 50 provides a force in a direction away from each other (53 and 55 of FIG. 8), the second coupling unit The force 30 is applied to the first engagement portion 20 in the direction of the arrow, that is, in the direction in which the portable device 5 is closed. In the second elastic force providing unit 60, the slide connecting portion 40 exerts a force in a direction opposite to the arrow with respect to the first coupling portion 20, that is, in the direction in which the portable device 5 opens, but the second coupling portion 30 The movement is restricted by the stopper (34 in Fig. 4), so that the portable device 5 remains stable in the closed state. At this time, each elastic member is set so that the elastic force by the first elastic force providing unit 50 is greater than the elastic force by the second elastic force providing unit 60. In this state, when the second unit 9 is moved relative to the first unit 7 to open the portable device 5, the second coupling portion 30 of the opening and closing device 10 is connected to the first coupling portion ( It moves to the direction opposite to arrow with respect to 20), and it will be in the state shown in FIG. In the state of FIG. 5B, when the second coupling part 30 is further moved in the direction of the arrow with respect to the first coupling part 20, the second coupling part 30 is provided by the first elastic force providing part 50. ) Is moved in the direction of the arrow that is automatically opened with respect to the first coupling portion 20, and further, the second elastic force providing unit 60 moves the slider connection portion 40 with respect to the first coupling portion 20 in the direction of the arrow. And further open as shown in Figs. 5C and 6C as a whole. At this time, in the state of the second elastic force providing unit 60, as shown in Figure 7 (b), the two connecting parts (644, 664) is opened to the maximum. In addition, since not only the first elastic force providing unit 50 but also the second elastic force providing unit 60 provide a force in the open direction, the portable device 50 maintains the open state more stably. Since the process of closing the portable device 5 is the reverse of the above-described opening process, a detailed description thereof will be omitted.

Although the present invention has been described with reference to the above embodiments, the present invention is not limited thereto. Those skilled in the art will appreciate that modifications and changes can be made without departing from the spirit and scope of the present invention and that such modifications and changes also belong to the present invention.
