The display 110 may output a desired screen to the user or serve as a user interface receiving a command from the user. As the display unit 110, a liquid crystal display (LCD), organic light emitting diodes (OLEDs), thin film transistors (TFTs), or the like may be used. The display 110 may be implemented to have a touch screen function to receive an operation command from a user.

As shown in FIG. 2, a main key input unit 210 for receiving an operation command from a user may be formed on an upper surface of the lower case 200, and the upper case 100 slides to the outside. May be exposed. The main key input unit 210 may be provided in the form of a keypad including a plurality of key buttons. Meanwhile, as shown in FIG. 1, an auxiliary key input unit 120 may be installed at a lower end of the display unit 110 of the upper case 100 to assist a function of the main key input unit 210. The auxiliary key input unit 120 may be installed at an upper end or a side of the display 110.

The slide-type portable terminal 1 controls the operation mode of the portable terminal 1 according to the position of the upper case 100 when the upper case 100 slides and moves. In particular, the upper case 100 is a lower case. The position (Slide Down) coupled to the 200 (slide down) and the position of the state in which the upper case 100 slides (slide up) may be sensed. Therefore, the operation mode of the mobile terminal 1 may be controlled according to the state in which the upper case 100 is coupled to the lower case 200 or the state in which the upper case 100 slides and moves.

3 is an exploded perspective view showing an example of a sliding detection device of a slide-type portable terminal according to an embodiment of the present invention.

As shown in FIG. 3, the sliding module 300 is installed on the link unit 330, the sliding guide 310 installed on the upper surface of the lower case 200, and the lower surface of the upper case 100. It may include a sliding plate 320 which is moved by sliding under the guide of the sliding guide 310.

The sliding guide 310 mounted on the lower case 200 and the sliding plate 320 mounted on the upper case 100 may be coupled to each other to be slidably movable. Therefore, when the upper case 100 is moved by sliding in a direction away from the lower case 200, both ends of the sliding plate 320 along the guide groove 311 formed at both ends of the sliding guide 310, the lower case It can move in the longitudinal direction of the (200).

On the other hand, the sliding guide 310 or the sliding plate 320 may be formed with at least one stop (not shown) for limiting the sliding movement of the upper case 100. The stop portion may be made of a material such as rubber to mitigate impact when limiting sliding movement of the upper case 100.

The link unit 330 may be installed between the sliding guide 310 and the sliding plate 320. At this time, one end of the link unit 330 may be rotatably coupled to the sliding guide 310, and the other end of the link unit 330 may be rotatably coupled to the sliding plate 320. A plurality of link units 330 may be installed as necessary.

As shown in FIG. 3, the link part 330 is connected to one side of the body part 331 and one end of the body part 331, and the sliding guide 330 is formed through the first hinge part 334 formed at the other end thereof.

As described above, according to an embodiment of the present invention, the magnet may be provided in the link unit 330 that moves according to the sliding movement of the upper case 100 without having a separate magnet. In an example, the body 331, the first link spring 332, or the second link spring 333 may have magnetic properties. In the case of Figure 3, it is preferable to have a magnetic portion in the body portion 331. However, the present disclosure is not limited thereto, and a member having magnetic properties may be determined according to a change in position according to a sliding movement of the upper case 100, a position of the detection sensor 340, and the like.

For example, instead of installing the sensing sensor 340 at the center of the width direction of the lower case 200 as shown in FIG. 3, the position away from the first hinge portion 334 which becomes the rotation axis of the link portion 330, that is, In FIG. 3, the second link spring 333 is preferably magnetic when it is installed at the left portion of the lower case 200 in the width direction. When the second link spring 333 having a large change in position according to the sliding movement of the upper case 100 has magnetic properties, malfunction of the detection sensor 340 may be reduced, thereby increasing the recognition rate.

When the upper case 100 is moved by sliding, the second hinge portion 335 of the link unit 330 coupled with the upper case 100 moves along the upper case 100, and the link unit 330 is It may rotate around the first hinge portion 334 coupled with the lower case 200. Even when the link unit 330 rotates, since the first link spring 332 and the second link spring 333 have elasticity, their lengths may vary. After the upper case 100 slides and moves, the second hinge portion 335 of the link portion 330 is positioned above the first hinge portion 334 of the link portion 330 and the link portion 330. Body portion 331 of the) may be located on the detection sensor 340. Accordingly, the detection sensor 340 outputs a high level signal, and thus, the upper case 100 is slid and moved, that is, the slide up state.

3 to 4B illustrate that the sensing unit 340 is installed such that the link unit 330 is close to the sensing sensor 340 when the upper case 100 is slid and moved. In a state in which the lower case 200 is coupled, the detection sensor 340 may be installed so that the link unit 330 approaches the detection sensor 340. In this case, the sensing sensor 340 outputs a high level signal in a state where the upper case 100 and the lower case 200 are coupled to each other, and the low level signal in the state where the upper case 100 is slid and moved.

The second gear part 412 is engaged with the first gear part 411 so that the first gear part 411 may rotate about the rotation axis when the upper case 100 slides and moves. In the example of FIG. 5, the second gear part 412 is preferably magnetic.

On the other hand, as shown in Figure 5, the first gear portion 411 has the form of a pinion gear (pinion gear), the second gear portion 412 has the form of a rack gear (Rack Gear) corresponding thereto. Can be. The first gear part 411 may be formed in a substantially semi-circular shape in consideration of the sliding movement distance of the upper case 100.
