The operation of the present embodiment will be described below.

4 and 5 are exploded perspective view showing a closed state of the terminal shown in Figure 1, Figures 6 and 7 are exploded perspective view showing an open state of the terminal shown in FIG.

First, in the closed state of the terminal, the slide body 30 on which the LCD screen 32 is installed is partially or completely entered into the storage space 14 of the main body 10. In this case, the slide body 30 is in a state in which the plurality of first cross bars 130 and the second cross bars 140 are compressed through the second bracket 170. Accordingly, the torsion spring 150 maintains the tensioned state.

And the hook 112 of the sliding bar 110 is fastened to the engaging projection 34 of the slide body 30 to maintain the slide body 30 is retracted into the storage space (14).

In this state, in order to pull out the slide body 30, the button 120 protruding to the side of the main body 10 is pressed. As the button 120 is pressed, the button 120 and the sliding bar 110 are moved at the same time so that the hook 112 is separated from the locking protrusion 34 of the slide body 30. At this time, the first pin 22 formed on the main body 10 is inserted into the first long hole 114 of the sliding bar 110 so that the sliding bar 110 can perform linear movement only. Guide them so they do not deviate

When the hook 112 is separated from the locking protrusion 34, the slide body 30 is accommodated by the elasticity of the first cross bar 130 and the second cross bar 140, which receive the elasticity of the plurality of torsion springs 150. It exits from the space 14 to the outside. At this time, when the button 120 is released, the sliding bar 110 protrudes again by the elasticity of the compression spring 116.

When the slide body 30 exits to the outside, the LCD screen 32 is exposed to the outside, so that the user can use the unique function of the terminal while watching the LCD screen 32.

As described above, the slide body 30 is slid outwardly so that the first cross bar 130 and the second cross bar 140 that receive the elasticity of the torsion spring 150 by pressing the button 120 are moved. Since the slide body 30 is automatically pushed, the user can open the terminal with one hand.

In addition, since the first cross bar 130 and the second cross bar 140 continue to receive the elasticity of the torsion spring 150 even after the slide body 30 is drawn out, the slide body 30 is pushed in the direction in which the slide body 30 is drawn out. The body 30 is maintained in the drawn out state. Therefore, a separate stopper for fixing the state in which the slide body 30 is drawn out is not necessary.

Meanwhile, to close the terminal while the slide body 30 is drawn out, the user pushes the slide body 30 into the storage space 14 by hand.

By this operation, the slide body 30 pushes the first cross bar 130 and the second cross bar 140 and enters the storage space 14. Accordingly, the torsion spring 150 is in a tensioned state, and the first cross bar 130 and the second cross bar 140 rotate relative to each other, and both ends thereof are in the state of being most widened in the lateral direction.

When the slide body 30 is sufficiently inserted into the storage space 14, the locking protrusion 34 formed on the slide body 30 is caught by the hook 112 of the sliding bar 110. Accordingly, the slide body 30 is maintained in the storage space 14.

As described above, the present invention provides a state in which the main body 10, the slide body 30 slidably coupled from the main body 10, and the slide body 30 are inserted into the main body 10, or A portable terminal having a stopper part for fixing to one of the pulled out states, and a sliding type opening and closing device having an elastic part for applying elasticity in a direction in which the slide body 30 is drawn out from or drawn out from the main body 10. As the stopper part operates, the slide body 30 is automatically opened by the action of the elastic part, thereby providing convenience to the user, and the stopping force is generated by the elastic part of the elastic part in the state in which the slide body 30 is drawn out. By omitting the stopper, the manufacturing cost can be reduced.
