In addition, since the elastic means 400 elastically supports the main body case 100 and the slide unit case 200 in opposite directions, a member having a predetermined elastic force is preferable.

In addition, as illustrated in FIG. 15, the elastic spring 410 protrudes in one direction of the leaf spring 410 and moves to be in contact with the elastic spring 410 so as to move in contact with the spring spring 410. ) Has an elastic portion moving groove formed on both sides of the body portion case 100 or the slide portion case 200 is not provided.

That is, the leaf springs 410 are provided at both sides of the slide part case 200, and the body part case 100 has an elastic part moving groove formed therein, so that the elastic part 412 of the leaf spring moves the elastic part. It is located in the groove.

In addition, in the opposite case, the leaf springs 410 are provided at both sides of the main body case 100, and the slide unit case 200 may have an elastic portion moving groove.

As shown in FIGS. 11 to 16, the leaf spring 410 is formed such that the elastic spring 410 of the leaf spring is seated when the slide case 200 slides down. A lower groove 420 formed at one side of both sides of the main body case 100 or the slide case 200 which is not provided; When the slide part case 200 slides up, the elastic part 412 of the leaf spring is positioned so that the body part case 100 or the other side of the slide part case 200 that is not provided with the leaf spring 410 is located. An upper groove 430 formed on the upper groove 430; And both sides of the body part case 100 or the slide part case 200 in which the leaf spring 410 is not provided so that the elastic part 412 of the leaf spring is positioned when the slide part case 200 slides. The slide guide groove 440 is formed in the slide direction from one end of the lower groove 420 to the other end of the upper groove 430.

In the present embodiment, a slight play occurs due to the predetermined space 340 described above in the slide-down state, wherein the leaf spring 410 faces the main body case 100 and the slide unit case 200. It pushes in the direction to attenuate the play and serves to reduce noise.

In addition, in the slide-up state, the slide unit case 200 slides down when the above-described coil spring 330 maintains more than a holding force that can be maintained in the slide-up state due to a sudden action when a user calls. Since the leaf spring 410 pushes the body part case 100 and the slide part case 200 in opposite directions to each other, the leaf spring 410 prevents the slide down by increasing the holding force.

15 and 16, a guide moving groove 413 may be further formed at the center of the leaf spring elastic part 412 so that there is no flow in the elastic part moving groove when sliding.

In addition, the elastic portion moving groove may further have a guide rail (not shown) corresponding to the guide moving groove 413 so that the leaf spring elastic portion 412 is guided without flow.

11 to 16, the plate portion 411 of the leaf spring is coupled to both sides of the main body case 100 or the slide unit case 200 so that the leaf spring 410 is provided. The coupling groove 460 may be formed.

In addition, the elastic means 400 may be formed integrally with the shape of the leaf spring on any one side of the main body case 100 or the slide unit case 200.

That is, in other words, the elastic member 410 may be an integral structure when the main body case 100 or the slide unit case 200 is manufactured.

Hereinafter, the operation and effects of the slide-type mobile communication terminal having the noise reduction and the slide malfunction prevention structure in the vibration mode of the present invention configured as described above will be described with reference to the accompanying drawings.

FIG. 17 is a partial cross-sectional view showing the operation of the leaf spring from the slide down state to the slide up state in the embodiment shown in FIG. 7, (a) shows the slide down state, and (b) shows the slide down state (C) shows the final process of the slide-up in the slide-down state, and (d) shows the slide-up state.

As shown in FIG. 17A, one side of the leaf spring 410 is coupled to the slide case 200 in the slide-down state, and the other side is positioned in the lower groove 420 formed in the main body case 100. In addition, the slide part case 200 and the main body case 100 are pushed in opposite directions by the elastic force to attenuate the clearance of the predetermined space 340 to reduce noise in the vibration mode.

In addition, as shown in FIGS. 17B and 17C, as the slide part case 200 slides up, the leaf spring 410 moves out of the lower groove 420 to slide the groove. 440 slides up toward the upper groove 430.

In addition, as shown in Figure 17 (d), when the slide is completely up, one side of the leaf spring 410 is coupled to the slide portion case 200, the other side is formed in the upper groove (100) 430, the slide case 200 and the main body case 100 by the elastic force in the opposite direction to each other, the user slides down by the coil spring 330 due to the sudden action during the call The force that can maintain the slide-up state is increased than the force that can be, it is a slide down to prevent the problem of ending the call.

As described above, according to the present invention, in the vibration mode of the terminal using the leaf spring, the unique noise coming from the slide structure is reduced, and the user is in a slide-down state due to a sudden movement during a call, and the call is terminated. It is effective to prevent.
