The operation of the slide module for a mobile communication terminal according to the present invention having the above configuration will be described with reference to the accompanying drawings.

In the normal state, that is, the standby state, as shown in FIG. 2A, the mobile communication terminal 1 is positioned with the second member 3 stacked on top of the first member 2. In this state, as shown in FIG. 5, the slide module for the mobile communication terminal attempts to push up the movable plate 20 on the fixed plate because the actuator 30 in the compressed state tries to extend. By the actuator 30, one end of the rotary link 41 connected to the other end of the actuator 30 is in contact with the inner wall of the working groove 24, and supports the actuator when the actuator 30 is extended. . One end of the actuator 30 supported by the other end pushes down the moving plate 20 and the second member 3 with respect to the fixing plate 10.

However, as the guide 12 is restrained by the stopper 42, the moving plate 20 can no longer be lowered, and continues to maintain the state of FIG. That is, by the actuator 30, the moving plate 20 tries to move down, but the guide 12 is stopped by the stopper 42 whose tip is exposed to the guide groove 22. In particular, the guide 12 is located in the seating groove 42a formed in the stopper 42, the guide 12 is to maintain the predetermined position of the guide groove 22, the mobile communication terminal 1 is shown in Figure 2a The standby state as shown in FIG.

In this state, when the user pushes up the second member 3 to make a call, the actuator 30 is temporarily compressed by a force exerted by the user, and then a kind of critical state in which the maximum compression is achieved (Fig. 6). The second member 3 is automatically slid upward by the actuator 30.

When the user starts to push up the second member 3 in the standby state as shown in FIG. 5, since the action force exerted by the user is greater than the elastic force of the actuator 30, the partially extended actuator 30 is provided. The slider 32 is inserted into the housing 31 and further compressed. Subsequently, when the second member 3 is continuously pushed up, as shown in FIG. 6, the actuator 30 becomes a kind of critical state that is compressed to the maximum, and beyond this state, the actuator 30 is compressed by the compressed actuator 30. The second member 3 slides up even if the user does not push up the second member 3. That is, since the actuator 30 is continuously extended, the second member 3 is slid upward until the actuator 12 is positioned at the lower end of the guide groove 22 while the actuator 30 is extended. The slide module for the mobile communication terminal is in a state as shown in FIG. 7, and the mobile communication terminal is in a state as shown in FIG. 2c.

On the other hand, in the state where the second member (3) is to slide up, the actuator 30 is to continue to extend, so that the rotary link 41 is in contact with the side wall of the working groove 24 to extend the actuator (30). I support it.

As such, when the second member 3 is slid upward and the keypad 4 provided below the first member 2 is exposed to the outside, the telephone number for the call and SMS transmission using the keypad 4 is exposed. You can enter characters, etc.

On the other hand, through the reverse process of the above, that is, the process of sliding the second member 3 up in the standby state, the second member 3 in the state shown in FIG. Move to position the second member 3 on the top of the first member 2.

In particular, when the second member 3 is moved downward, the guide 12 is located in the middle portion where the upper end of the guide groove 22 is close, but the tip portion of the stopper 42 of the guide groove 22 Since the guide 12 is not in contact with the upper end of the guide groove 22, the guide 12 is maintained in contact with the seating groove 42a of the stopper 42.

In the usual state as the mobile communication terminal 1 is shown in FIG. 2A, the user moves the second member 3 downward with respect to the first member 2 through an operation, whereby the first member 2 The additional function key (7) additionally provided to the mobile communication terminal is exposed to the part exposed to the outside in addition to the upper surface.

When the user pushes down the second member 3, the guide 12 moves over the stopper 42 by the force exerted by the user. That is, the stopper 42 is slidably elastically supported in the stopper mounting groove 23. When the force applied by the user causes the guide 12 to push the stopper 42, FIG. 5. In the illustrated state, as shown in FIG. 8, the guide 12 travels over the portion protruding from the tip of the stopper 42 at the maximum in the guide groove 22, and then the second member ( When 3) is lowered, it is located at the upper end of the guide groove 22 as shown in FIG. 9 and is constrained by the guide groove 22 and the seating groove 42b.

The user starts to lower the second member 3 until the guide 12 reaches the top of the curved portion of the stopper 42, i.e., until the state of the second member 3 is changed from the illustrated state of FIG. 5 to the state of FIG. 8. 3), the stopper 42 is guided because the shape of the stopper 42 is bent in the following section and the elastic member 43 continues to push the stopper 42 into the guide groove 22. Advancing into the groove 22 allows the guide 12 to be seated in the seating groove 42b.

At this time, since the end of the actuator 30 is connected to the fixing plate 10, when the moving plate 20 is lowered with respect to the fixing plate 10, the other end of the actuator 30 is the same. Pulling the rotary link 41, the rotary link 41 is rotated inside the working groove (24).

Therefore, when the second member 3 is lowered, the second member 3 is not supported by the elastic member 33 of the actuator 30 but by the elastic member 43 attached to the stopper 42. Is lowered down.

Through such a process, the mobile communication terminal slide module of the present invention is shown in FIG. 5, and the moving plate (with respect to the fixed plate 10 so as to be in the state shown in FIG. 9 through the state shown in FIG. 8). By sliding 20 downward, the second member 3 of the mobile communication terminal 1 moves downward relative to the first member 2.

As described above, when the second member 3 moves downward with respect to the first member 2, the upper part of the upper surface of the first member 2 is exposed to the outside. By further exposing the portion to the first member 2, various additional function keys 7, such as MP3 operation switch, DMB operation switch, etc., are applied to the additionally exposed part. It can be arranged.

Meanwhile, by moving a part of the existing function keys 4 arranged on the same plane as the screen 5 from the second member 3 to the first member 2 newly exposed to the outside, the mobile communication terminal 1 ), The size of the screen 5 can be increased.

To return the second member 3 to its original position, the user raises the second member 3 upward, and by the operating force of the user, by the reverse process of the above-described process, the guide 12 causes the stopper ( 42) you will cross. When the guide 12 crosses the stopper 42, the guide 12 is located at a position where the stopper 42 and the guide groove 22 contact each other, that is, the seating groove 42a of the stopper 42.
