Although optional, one side of the main unit 10 is equipped with a camera 14 for capturing an image such as a picture or a picture.

The outer surface of the slider 20 is provided with a large screen liquid crystal 21 in which a character or a screen is formed, including a phone number, a state of charge of the battery, whether vibration is present, an alarm state display, and the like. The liquid crystal 21 is adopted as a so-called LCD. The receiver 22 for receiving the voice from the other party is formed in the upper part of the liquid crystal 21.

The battery pack 15 is detachably coupled to the rear surface of the main part 10. The battery pack 15 is generally adopted as a rechargeable type, and according to the type thereof, a lead-acid battery, a nickel cadmium (Ni-Cd) battery, a nickel hydride (Ni-Mh) battery, and a lithium-ion rechargeable battery (Lithium-ion) ), A lithium polymer rechargeable battery (Polymer) and the like may be applied.

On the other hand, the main unit 10 and the slider 20 has a coupling cross-section of the dovetail (Dove-Tail) shape so that the slider 20 can be moved relative to the main unit 10. That is, when a rail is formed in the main part 10, a rail groove is formed in the slider 20 so that the rail can slide along the rail groove. Of course, a rail groove may be formed in the main part 10 and a rail may be provided in the slider 20. This is a universal structure of the sliding type mobile terminal, so detailed illustration thereof will be omitted.

3 and 4 are diagrams illustrating a structure according to opening and closing operations of the slider illustrated in FIGS. 1 and 2, respectively.

As shown in these figures, the push button 18 (refer to the enlarged portion of FIG. 2) is provided on the side of the main part 10, and the pressing force of the push button 18 is provided on the main part 10 and the slider 20. The power transmission part 30 which slides the slider 20 with respect to the main part 10, and opens the area | region of the input button 11 of the main part 10 based on is provided.

That is, when the push button 18 is pressed, the mobile terminal can be used as shown in FIG. 2, and when the press button is released, the mobile terminal returns to the initial mode as shown in FIG. 1. Therefore, for convenience of use, or for one-handed operation, it is relatively convenient when the user wants to use the mobile terminal by sliding open the slider 20 with respect to the main part 10 while foreign matter is on the user's finger. It works.

The power transmission unit 30 includes a driving block 31 having one end contacting the pushbutton 18 and moving along the pressing direction of the pushbutton 18, and the main unit 10 as the driving block 31 moves. ), The driven block 34 moves upward and downward, and one end of the driven block 34 contacts the rocker part 25 provided on the slider 20, and the driven block 34 is pushed by the pusher button 18. It includes a link member 36, both ends of which are linked to the drive and driven blocks (31, 34) to push 25.

The driving block 31 is provided in the empty driving guide rail 32 formed along the pressing direction of the push button 18 to reciprocate in the driving guide rail 32. Similarly, the driven block 34 is provided in the inner rail 35 during the empty bell to reciprocate in the inner rail 35 during the bell. At this time, as shown, the driving and longitudinal inner rails 32, 35 are arranged at substantially right angles.

Due to this structure, the link member 36 is inclined. Therefore, as shown in Figure 3, when the push button 18 is pressed in the "A" direction to move the drive block 31 to the right along the drive guide rail 32, the driven block 34 in the inner rail 35 for a long time Is to be able to push the rocker portion 25 while moving upward in the "B" direction. The slider 20 is opened by pushing the rocker portion 25 in the B " direction by the driven block 34 (see Fig. 2).

On the other hand, the power transmission unit 30 is an elastic member 38, the both ends elastically biased in the direction to return the drive block 31 to the original position in contact with the inner wall of the drive block 31 and the inner rail 35 for a long time, respectively. It further includes. As the elastic member 38, a compression spring may be employed.

Therefore, when the force pressing the pushbutton 18 in the state of FIG. 4 is removed, the compressed elastic member 38 elastically expands and pushes the driving block 31 against the inner wall of the inner rail 35 during the longitudinal period. The pushbutton 18 can be returned to its original position. For reference, when the pushbutton 18 is pressed, the driving guide rail 32 is provided with a button catching jaw 33 that forms a moving limit point at which the pushbutton 18 is pressed.

As shown in FIG. 3, when the pushbutton 18 is pressed in the “A” direction, the driving block 31 moves to the right along the driving guide rail 32. Accordingly, the link member 36 presses the driven block 34 upwards in the inner rail 35 during the longitudinal period as the inclination gradually increases. As such, the slider 20 can be opened because the driven block 34 pushes the rocker portion 25 while moving upward in the "B" direction (see FIG. 2). At this time, the elastic member 38 is in a compressed state.

Next, the force that pressed the pushbutton 18 is removed. Then, the compressed elastic member 38 is elastically expanded while pushing the drive block 31 to the left side against the inner wall of the inner rail 35 during the longitudinal period so that the push button 18 can be returned to its original position. As the driving block 31 moves to the left side, the inclination of the link member 36 is lowered, thereby pulling the driven block 34 coupled to the link member 36 to lower the rocker portion 25. Make sure As the rocker part 25 moves downward, the slider 20 opens again, as shown in FIG. 1, to close the main part 10.

As described above, according to the present invention, the slider 20 can be easily opened and closed with respect to the main part 10 only by the operation of the pushbutton 18. Therefore, not only is it convenient to use, but it is possible to prevent the fingerprint of the finger or the foreign matter of the finger from being contaminated with the liquid crystal 21.
