SLIDE MODULE AND MOBILE COMMUNICATION TERMINAL WITH THE SAME {SEMI-AUTO SLIDE MODULE AND MOBILE PHONE HAVING THE SAME}

The present invention relates to a slide module and a mobile communication terminal having the same. More particularly, the size of the slide module and the size of the mobile communication terminal are expanded. It relates to a slide module and a mobile communication terminal having the same.

In general, a sliding type mobile communication terminal includes a lower body on which a keypad or a keyboard is mounted, an upper body on which a liquid crystal display is mounted, a slide module embedded between the lower body, and an upper body to enable relative movement of both. .

Here, looking at the slide module in detail, the slide module is composed of a lower plate and an upper plate slidably coupled to each other, the lower plate is fixed to the lower body and the upper plate is fixed to the upper body, thereby the lower plate and the upper plate When the relative sliding of the lower body and the upper body is moved relative.

In order to more easily open and close the upper body through the relative movement of the lower body and the upper body, the recent mobile communication terminal has a structure that allows the upper body to be opened and closed automatically, that is, the elastic spring between the lower plate and the upper plate The main structure is to make it semi-automatic sliding by mounting.

According to this structure, if the upper body is moved only a predetermined distance with respect to the lower body, since the upper body can be automatically slid by the elastic restoring force of the elastic spring thereafter, the user can conveniently open and close the upper body will be.

However, the current mobile communication terminal relies on only elastic springs to maintain the open or closed state of the upper body, so that the upper body is often moved by a fine external force. Means are not provided separately.

Accordingly, when the user carries the mobile communication terminal, an unexpected opening of the upper body occurs, and thus there is a problem that power of the mobile communication terminal may be consumed.

In addition, the mobile communication terminal should frequently open and close the upper body for its use. When the elastic force of the elastic spring in the slide module is weakened due to the frequent opening and closing of the upper body, unwanted opening and closing of the upper body may occur more frequently. .

This problem is inevitably followed by a conventional structure in which an elastic spring is mounted between the lower plate and the upper plate so as to slide semi-automatically.

On the other hand, the sliding type mobile communication terminal currently applied has a variable size of the upper surface of the lower body on which the keypad is mounted. Recently, users tend to prefer mobile communication terminals equipped with various functions, and thus, the area occupied by the keypad required to implement each function needs to be widened.

To this end, when the area of the lower body is widened, since the overall size of the mobile communication terminal increases, there is a problem that the convenient portability of the mobile communication terminal should be basically provided.

Therefore, there is a need for development of a slide module that allows the size to be expanded in use without increasing the basic size of the mobile communication terminal, and in particular, such an operation can be implemented semi-automatically.

In addition, the number of mobile communication terminals using a QWERTY keyboard is increasing recently. The QWERTY keyboard is arranged in the longitudinal direction of the mobile communication terminal, unlike the keypad of the conventional mobile communication terminal. In order to use the QWERTY keyboard, the mobile communication terminal has a structure sliding in the width direction.

However, when the QWERTY keyboard is installed, unlike the conventional mobile communication terminal, it is not easy for the user to press the keyboard after opening the upper body with one hand, and hold the mobile terminal with one hand and press the keyboard with the other hand. I use it. Accordingly, the necessity of a handle function for stably holding a mobile communication terminal for use of a qwerty keyboard is emerging.

In addition, the QWERTY keyboard of the conventional mobile communication terminal is inconvenient to be pressed two at a time because the keyboard is arranged very densely due to the narrow space of the lower body.

In order to solve this problem, it may be considered to increase the area of the lower body, but as described above, there is a problem that impedes convenient portability due to the increase in the overall size of the mobile communication terminal, which is not a fundamental solution.

1 to 3, the slide module 10 according to the first embodiment of the present invention is the base plate 100, the first sliding plate 200, the second sliding plate 300 and the first An elastic body 400 is included.

The slide module 10 is characterized in that the first sliding plate 200 is automatically slid by the first elastic body 400 when the second sliding plate 300 is slid in one direction (left side in the drawing). do.

The base plate 100 may be formed in a flat plate shape, preferably, the left and right lengths are formed in a rectangular shape longer than the length of the front and rear sides. And a pair of first guide portion 110 for sliding the first sliding plate 200 is formed on both sides of the upper surface of the base plate 100, as long as the sliding side of the second sliding plate 300 on both sides. A pair of second guide portion 120 is formed.

In FIGS. 1 to 3, only the guide part is formed on the base plate 100 for the slidable coupling of the first and second sliding plates 200 and 300, but the guide is not limited thereto and is slidable. It is also possible to form the part in the first or second sliding plate.

However, in the first embodiment of the present invention, it is considered that it is most preferable to form the first and second guide parts 110 and 120 on the upper and lower surfaces of the base plate 100, and only the embodiments thereof will be described. .

Here, the first guide part 110 and the second guide part 120 are formed in a direction crossing each other. That is, as shown in FIG. 2, the first guide part 110 is bent upward at both sides of the upper surface of the base plate 100, specifically, at the left and right ends thereof, and the second guide part 120 is formed of the base plate 100. ) Is bent downward at both sides, specifically front and rear ends.

In this case, the first and second guide parts 110 and 120 form guide grooves 112 and 122, respectively, and the guide grooves 112 and 122 have an approximately 'c' shape.

Therefore, the first and second sliding plates 200 and 300 may slide in a direction crossing each other through the first and second guide parts 110 and 120.

Meanwhile, hinge brackets 130 are formed on the upper surfaces of the pair of first guide parts 110 so as to face each other, and the hinge brackets 130 are provided for coupling of the first elastic body 400. Detailed description will be described later.

For reference, the base plate 100 may be made of a stainless material, the inside of the guide groove 112 formed by the first guide portion 110 on both sides, polyoxymethylene (POM), polyphenylene oxide (PPO) A protective member (not shown) made of engineer plastic material such as) may be provided.

The first sliding plate 200 is a member that is slidably coupled to the first guide portion 110 of the base plate 100, and is formed in a substantially flat shape, and on both sides of the first guide portion of the base plate 100. A guide rail 210 corresponding to the guide groove 112 formed by the 110 is formed. The first sliding plate 200 may be made of stainless material.

The second sliding plate 300 is a member that is slidably coupled to the second guide portion 120 of the base plate 100 and slides in a direction crossing with the first sliding plate 200. Like the base plate 100, the length of the left and right ends is formed in a rectangle longer than the length of the front and rear ends.

In addition, at the rear end of the drawing of the second sliding plate 300, a first stopper 310 protruding upward may restrict the sliding of the first sliding plate 200, and the first stopper 310 may have a first sliding angle. It protrudes to a height that can be in contact with the rear end of the plate 200.

That is, the first sliding plate 200 is located at the upper side and the second sliding plate 300 is located at the lower portion of the base plate 100, so that the sliding of the first sliding plate 200 is limited. The stopper 310 protrudes upward from the rear end of the second sliding plate 300 so as to extend beyond the base plate 100 to a height at which the rear end of the first sliding plate 200 contacts.

The first stopper 310 serves to restrict the first sliding plate 200 from sliding when the first and second sliding plates 200 and 300 are coupled to the base plate 100. When the sliding plate 300 is slid in one direction (left direction in the drawing), the sliding restriction by the first stopper 310 is released, so that the first sliding plate 200 slides behind the base plate 100 in the drawing. do.

The first elastic body 400 serves to provide an elastic restoring force for the automatic sliding of the first sliding plate 200, one end is coupled to the base plate 100 and the other end is coupled to the first sliding plate 200. do.

Accordingly, when the sliding restriction of the first sliding plate 200 by the first stopper 310 is released when the second sliding plate 300 is slid, the first sliding plate 200 is moved by the first elastic body 400. Can be sliding automatically.

Preferably, the first elastic member 400 is seated on the upper surface of the first sliding plate 200, one end of which is formed on the lower surface of the hinge bracket 130 formed on the first guide part 110 of the base plate 100. It is provided to be rotatable, and the other end is rotatably coupled to the upper surface of the first sliding plate 200.

More preferably, the first elastic member 400 is provided such that the pair is symmetrical with each other, and in particular, one is arranged to have a predetermined inclination with respect to the center of the first sliding plate 200 and the other is symmetrical with this. It is efficient in terms of providing elastic restoring force and durability.

A tension spring may be applied to the first elastic body 400, and hinge portions (not shown) for coupling with the base plate 100 and the first sliding plate 200 may be separately provided at both ends.

In this case, it is particularly preferable that the first elastic body 400 is kept in a tensioned state. As described above, the first and second sliding plates 200 and 300 are coupled to the base plate 100 so that the first sliding plate 200 of the second sliding plate 300 is connected to the first sliding plate 200. When the sliding is limited, it means that the first elastic body 400 is in a tensioned state.

Therefore, when the second sliding plate 300 is slid in one direction, the first sliding plate 200 is automatically slid by the restoring force of the first elastic body 400 which is in the tensioned state.

For reference, the first elastic body 400 may be applied without limitation as long as it is an elastic means capable of providing a restoring force for sliding the first sliding plate 200 in addition to the tension spring.

On the other hand, the slide module 10 according to the first embodiment of the present invention preferably further includes a second elastic body in order to allow the second sliding plate 300 to automatically slide.

That is, as described above, the sliding of the first sliding plate 200 may be automatically performed by the first elastic body 400, but the sliding of the second sliding plate 300 must be performed manually, so that the second sliding is performed. The second elastic body is provided for the automatic sliding of the plate 300.

As shown in FIGS. 2 and 3, the second elastic body 500 has one end coupled to the base plate 100 and the other end coupled to the second sliding plate 300 so as to slide on the second sliding plate 300. To provide elastic restoring force.

Preferably, the second elastic body 500 has one end coupled to the bottom surface of the base plate 100 and the other end coupled to the second sliding plate 300, and particularly, the sliding direction of the second sliding plate 300 It is arranged to provide elastic restoring force in the same direction.

In this case, a tension spring may be applied to the second elastic body 500. When the second sliding plate 300 is slid in one direction (left direction in the drawing), the second elastic body 500 is in a tensioned state and the second sliding is performed. The plate 300 is provided with an elastic restoring force to slide in the other direction (the right direction in the drawing).

However, as described above, a first stopper 310 for limiting sliding of the first sliding plate 200 is formed at a rear end of the second sliding plate 300, and the first stopper 310 is a second sliding plate. When the 300 is slid in one direction and the first sliding plate 200 is slid backward in the drawing, since the first stopper 310 is in contact with the side surface of the first sliding plate 200, the second elastic body 500 Even if the elastic restoring force is provided to the second sliding plate 300 by the first stopper 310, the sliding is limited.

As a result, the first stopper 310 alternately serves to limit sliding of the first and second sliding plates 200 and 300.

Meanwhile, one end of the second elastic member 500 may be fixed to the base plate 100 by riveting, and the other end may be fitted into and coupled to the coupling groove 340 formed in the second sliding plate 300. have.

And it is necessary to maintain the sliding interval of the second sliding plate 300 by the second elastic body 500, for this purpose, the second sliding plate 300 is the long hole 320 and the second stopper 330 Has

Here, the long hole 320 of the second sliding plate 300 is formed in the sliding direction on the surface, the second stopper 330 is coupled through the long hole 320 to control the sliding interval of the second sliding plate 300. Done. In this case, the second stopper 330 is fixed to the bottom surface of the base plate 100.

For reference, the second stopper 330 is a cylindrical body portion 332 having a diameter corresponding to the long hole 320, and the body portion 332 is extended from the lower end of the body portion 332 is the long hole 320 It may include an expansion portion 334 to not completely penetrate, and a fixing portion 336 is fitted into and fixed to the insertion groove 140 formed in the base plate 100, furthermore, the body portion 332, expansion The fixing unit 334 may further include a fixing pin 338 coupled to and fixed to the base plate 100 through the fixing unit 336.

Although the configuration of the slide module according to the first embodiment of the present invention has been clearly described above, the description of coupling elements such as fixing pins is omitted in the coupling between the components, but this is in the technical field to which the present invention pertains. Those skilled in the art can only easily understand and apply.

Hereinafter, a schematic operation of the slide module according to the first embodiment of the present invention will be described with reference to FIGS. 4 to 6.

First, as shown in FIG. 4, when the first and second sliding plates 200 and 300 are coupled to the base plate 100, the first sliding plate 200 based on the base plate 100 is illustrated in the drawing. It is moved downward and the second sliding plate 300 is moved to the right in the drawing.

In this case, the first elastic member 400 is in a tensioned state to provide elastic restoring force upward in the drawing, but the first stopper 310 of the second sliding plate 300 is the rear end of the first sliding plate 200. Since the contact with the sliding of the first sliding plate 200 is limited.

The second sliding plate 300 is slid to the right in the drawing by the second elastic body 500, and this state is maintained as long as the second sliding plate 300 is not slid to the left in the drawing due to an external force. .

Subsequently, when an external force is applied to the second sliding plate 300 to the left in the drawing, as shown in FIG. 5, the second sliding plate 300 slides to the left, and the second elastic body 500 is in a tensioned state. The elastic restoring force is provided to the right side, and the sliding restriction of the first sliding plate 200 by the first stopper 310 is released.

Accordingly, the first elastic body 400 in the tensioned state is restored to its original shape and at the same time, the first sliding plate 200 automatically slides upward in the drawing.

In addition, the second elastic body 500 in tension state provides elastic restoring force so that the second sliding plate 300 slides in the right direction on the drawing, but the first stopper 310 of the second sliding plate 300 is made of Since the first sliding plate 200 is in contact with the side surface, the sliding of the second sliding plate 300 is limited, and this state is maintained unless an external force is applied so that the first sliding plate 200 slides downward.

Subsequently, when an external force is applied downwardly to the first sliding plate 200 in the drawing, the first sliding plate 200 is slid downward as shown in FIG. 6, and the first elastic body 400 is in the tensioned state again. The elastic restoring force is provided upward, and the first stopper 310 of the second sliding plate 300 is not in contact with the side of the first sliding plate 200.

Accordingly, the second elastic body 500 in the tensioned state is restored to its original shape and at the same time, the second sliding plate 300 automatically slides to the right in the drawing, in this case, the long hole 320 formed in the second sliding plate 300. ) And the second stopper 330 to control the right sliding interval of the second sliding plate 300.

Furthermore, since the first stopper 310 of the second sliding plate 300 is in contact with the rear end of the first sliding plate 200 again, the sliding of the first sliding plate 200 is limited to maintain the initial state.

A mobile communication terminal to which the slide module according to the first embodiment of the present invention is applied will be described with reference to FIG. 1.

As shown in FIG. 1, the mobile communication terminal includes a slide module 10, a lower body 20, a subbody 30, and an upper body 40. Since the technical features of the slide module 10 have been described above, only the necessary matters will be described herein.

The keypad 22 is mounted at the front of the lower body 20, and the base plate 100 of the slide module 10 is fixed at the rear of the upper body.

And the sub-body 30 is coupled to be slidable in one direction of the lower body 20, coupled to one end of the second sliding plate 300 of the slide module is integrally slid. In this case, a groove (not shown) in which one side of the lower body 20 can be inserted into the subbody 30 and a groove in which one end of the second sliding plate 300 is inserted can be inserted into the subbody 30. (Not shown) is preferably formed.

In addition, the upper body 40 is seated on the upper portion of the lower body 20, and is fixed to the first sliding plate 200 of the slide module 10 to be slidable. In this case, when the first sliding plate 200 of the slide module 10 slides with respect to the base plate 100, the upper body 40 slides with respect to the lower body 20.

Such a mobile communication terminal is a state in which the subbody 30 is coupled to one side of the lower body 20 and the upper body 40 is seated on the upper surface of the lower body 20 when the user does not use it. Maintained by the slide module. And since one side of the lower body 20 is fitted to the sub body 30 is coupled to the sub body 30 is not easily flow. This is for minimizing the state in which the mobile communication terminal is opened by a fine external force.

In order to use the mobile communication terminal, when the subbody 30 is pulled in one direction of the lower body 20 (left side in the drawing), the second sliding of the slide module 10 fixed to the subbody 30 is fixed. When the plate 300 is slid in the left direction and then the first stopper 310 of the second sliding plate 300 releases the sliding restriction of the first sliding plate 200, together with the first sliding plate 200. The upper body 40 is automatically opened to the rear of the lower body 20 is opened, the second sliding plate 300 and the sub-body 30 by the first sliding plate 200 is limited sliding, the upper bar The open state of the die 40 is maintained.

Therefore, the user can use the mobile communication terminal by moving only the subbody 30 to the left.

On the other hand, because the upper surface of the lower body 20 is expanded during the sliding of the sub-body 30, a space for the expansion of the QWERTY keyboard can be secured, and serves as a handle of the sub-body 30.

When the user wants to turn off the mobile communication terminal, when the upper body 40 is lowered downward by applying external force, the first sliding plate 200 slides downward together with the second sliding plate 300. When the first stopper 310 of) releases the sliding restriction of the second sliding plate 300, the subbody 30 together with the second sliding plate 300 automatically slides to the right side in the drawing of the lower body 20. The sliding of the first sliding plate 200 and the upper body 40 is limited by the first stopper 310 of the second sliding plate 300 to maintain the closed state of the upper body 40.

Therefore, when the user uses only the mobile communication terminal and lowers the upper body 40 downward, the user is in an automatic locking state.

7 is an exploded perspective view of a mobile communication terminal according to a second embodiment of the present invention, and FIG. 8 is an exploded perspective view of the slide module shown in FIG. 7.

As shown in FIG. 7 and FIG. 8, the mobile communication terminal according to the second embodiment of the present invention includes a slide module 10 ', a lower body 20', a subbody 30 ', and an upper body 40'. When the upper body 40 'is slid to the rear of the lower body 20' by a predetermined length, the upper body 40 'is automatically slid thereafter and the subbody 30' is automatically When the upper body 40 'is slid to the front of the lower body 20' by a predetermined length, the subbody 30 'is simultaneously lowered to one side of the lower body 20'. Sliding to the other side of ') to be so that the upper body 40' automatically slides thereafter.

That is, when the upper body 40 'is slid for use of the mobile communication terminal, the subbody 30' is slid at the same time so that the upper surface of the lower body 20 'is expanded, and the use of the mobile communication terminal is finished. When sliding the upper body 40 'in the opposite direction at the same time to the sub-body (30') is to be reduced to the initial state, in particular to ensure that these operations are made in conjunction with each other semi-automatically.

Here, the slide module 10 ', the lower body 20', the subbody 30 ', and the upper body 40' of the mobile communication terminal are composed of the slide module and the mobile communication terminal shown in Figs. Since there are many similar aspects in terms of technical features and the following, only the differences will be described.

First, the slide module 10 'will be described. The slide module 10' includes a base plate 100 ', a first sliding plate 200', a second sliding plate 300 ', and a first elastic body 400. '), And preferably further includes a second elastic body 500'.

Here, when the second sliding plate 300 'is coupled to the base plate 100', a part of the second sliding plate 300 'is exposed to the outside of the base plate 100', and a locking protrusion 350 'is formed on an upper surface of the exposed part. . The locking protrusion 350 'serves to allow the second sliding plate 300' to simultaneously slide when the upper body 40 'is slid, which will be described later.

In addition, in the slide module illustrated in FIGS. 1 to 3, a first stopper is formed on the second sliding plate to limit sliding of the first sliding plate, and the second sliding plate 300 ′ is separately provided with a first stopper. There is no need to provide a stopper.

The reason is that the first sliding plate 200 'does not slide even without a separate stopper, and the sliding limit of the second sliding plate 300' is limited by the locking projection 350 'of the second sliding plate 300'. And the rail groove 42 'of the upper body 40'. A more detailed description thereof will be described later.

One end of the first elastic body 400 ′ is coupled to the base plate 100 ′ and the other end is coupled to the first sliding plate 200 ′ to provide elastic restoring force for sliding of the first sliding plate 200 ′. In this respect, it performs a function similar to the first elastic body 400 of the slide module shown in FIGS.

However, unlike the first elastic member 400 of the slide module shown in FIG. 1 is installed to maintain the initial tension state, the first elastic member 400 'in this case is not subjected to any deformation so that no elastic restoring force is generated. It is installed in a state.

That is, one end of the first elastic body 400 ′ is rotatably coupled to the hinge bracket (not shown) of the base plate 100 ′, and the other end thereof is rotatable about the central portion of the first sliding plate 200 ′. Can be installed so that the pairs are arranged in mutually symmetrical positions. Accordingly, when the first sliding plate 200 ′ slides on the base plate 100 ′, the first elastic body 400 ′ is compressed to generate an elastic restoring force, and a dead point of the first elastic body 400 ′ is generated. After passing, the first sliding plate 200 'will be automatically slid thereafter.

As the first elastic member 400 ′, which is generally used in a slide module, it can be applied without limitation as long as it can be mounted between two slidable plates to be semi-automatically slidable. For example, various embodiments are possible, such as general compression coil springs, linear springs, helical springs, or spring assemblies. The first elastic body 400 ′ shown in FIGS. 7 and 8 is merely a means for illustratively describing the present invention. The various elastic means described above may be applied thereto.

Referring to the lower body 20 ', the subbody 30' and the upper body 40 ', as in the mobile communication terminal shown in Figure 1, the front of the upper body of the lower body 20' is equipped with a keypad and the upper surface The base plate 100 'of the slide module 10' is fixed to the rear side, and the subbody 30 'is coupled to one side of the lower body 20', but the second sliding plate 300 of the slide module 10 'is fixed. ') Is coupled to one end of the lower body 20' and slides in one direction, and the first body 40 'of the upper body 40' is fixed to the first sliding plate 200 'of the slide module 10' on the lower surface thereof. Sliding integrally with the sliding plate 200 '.

On one side of the upper body 40 ', a rail groove 42' into which the engaging protrusion 350 'of the second sliding plate 300' is inserted is formed. The rail groove 42 'has a straight portion 43' that is formed long in the sliding direction of the upper body 40 ', and is bent to the side of the upper body 40' at the straight portion 43 '. A curved portion 44 '.

The locking protrusion 350 'and the rail groove 42' perform two functions. First, sliding of the second sliding plate 300 'is restricted while the locking protrusion 350' is positioned at the straight portion 43 'of the rail groove 42'. That is, the locking protrusion 350 'serves as a stopper to prevent the second sliding plate 300' from sliding.

Second, when the locking projection 350 'enters the curved portion 44' of the rail groove 42 ', the sliding restriction of the second sliding plate 300' is released, so the upper body 40 'and the subbody Sliding of 30 'can be done simultaneously. That is, when the upper body 40 'is slid to the rear of the lower body 20' by a predetermined length, the locking protrusion 350 'of the second sliding plate 300' is the straight portion 43 of the rail groove 42 '. It passes through ') to reach the curved portion 44'. After the upper body 40 'is slid continuously, the locking protrusion 350' is moved along the curved portion 44 'of the rail groove 42', and thus the second sliding plate 300 'is slid. Will be.

In this case, when the locking projection 350 'is positioned at a portion where the straight portion 43' and the curved portion 44 'of the rail groove 42' are connected, the first elastic member 400 'is in a dead point state. In this case, the upper body 40 'is slid only until the locking projection 350' enters the curved portion 44 'of the rail groove 42'. Due to the elastic restoring force of), the upper body 40 'automatically slides, and at the same time, the second sliding plate 300' and the subbody 30 'also automatically slide.

In addition, although only the elastic restoring force of the first elastic body 400 ′ can automatically slide the upper body 40 ′ and the sub body 30 ′, it is to assist the automatic sliding of the sub body 30 ′. The second elastic body 500 ′ may be provided.

One end of the second elastic body 500 'is fixed to the bottom surface of the base plate 100' and the other end is fixed to the second sliding plate 300 'to provide elastic force for sliding to the second sliding plate 300'. As shown in FIG. 8, one end is fixed to a bottom surface of the base plate 100 'by a fixing pin (not shown) and the other end is compressed coil spring fixed to the second sliding plate 300'. Can be done.

In this case, the spring 500 'is preferably installed in a compressed state to have a restoring force to push the second sliding plate 300' to one side of the lower body 20 '.

As such, even when the spring 500 'is installed in a compressed state, the second sliding plate 300' and the subbody 30 are disposed while the locking protrusion 350 'is positioned at the straight portion 43' of the rail groove 42 '. ') Is not slid, and when the locking projection 350' enters the curved portion 44 'of the rail groove 42', the first elastic member 400 'and the second elastic member 500' are provided. The sliding of the second sliding plate 300 ′ and the subbody 30 ′ may be smoothly performed by the elastic restoring force.

On the other hand, while the upper body 40 'is slid in the direction opposite to the first sliding direction, the locking projection 350' is moved along the curved portion 44 'of the rail groove 42', so that the second sliding plate 300 'and the subbody 30' are also slid. In this case, when the locking projection 350 'is located at the portion where the curved portion 43' and the straight portion 44 'of the rail groove 42' are connected, the second sliding plate 300 'and the subbody 30 Sliding of ') is completed, and after that, the upper body 40' is automatically slid and reduced to the initial state due to the elastic restoring force of the first elastic body 400 '.

In this case, the first elastic body 400 ′ is installed without being deformed so that the elastic restoring force is not provided to the first sliding plate 200 ′, and the second elastic body 500 ′ is the second sliding plate 300 ′. It is installed in a compressed state to provide an elastic restoring force for pushing the to one side (left side in the drawing) of the lower body (20 '). However, since the locking projection 350 'of the second sliding plate 300' is located at the straight portion 43 'of the rail groove 42' of the upper body 40 ', the second sliding plate 300' ) And the sliding of the subbody 30 'is limited.

When the user wants to use the mobile communication terminal, as shown in FIG. 10, the first elastic body 400 ′ is slid to the rear of the lower body 20 ′ by a predetermined length to the rear of the lower body 20 ′. ) Passes through the dead point, after that the upper body 40 'is automatically slid by the first elastic body 400' and at the same time the first elastic body 400 'and the second elastic body 500' As a result, the subbody 30 'is automatically slid to one side (the left side in the drawing) of the lower body 20' (see FIG. 11). Accordingly, the user can use a mobile communication terminal having an expanded size.

When the user completes the use of the mobile communication terminal, when the upper body 40 'is slid to the front of the lower body 20' by a predetermined length, at the same time, the subbody 30 'is connected to the lower body 20'.
