The present invention relates to a sliding structure for an electronic device, and more particularly, to a sliding structure for an electronic device that can be thinned and improved user convenience.

In recent years, sliding structures have been introduced into portable electronic devices such as mobile phones, cameras, portable multimedia players (PMPs), and the like due to their ease of operation and high design preference.

Fig. 1A is a schematic perspective view showing an example of a conventional cellular phone, and Fig. 1B is a schematic partial perspective side view of the conventional cellular phone shown in Fig. 1A.

As shown in Figs. 1A and 1B, a conventional mobile phone 10 having a sliding structure includes a sign language unit 20 in which a display unit 2 is formed, and a talk unit in which an operation unit 3 such as a number key is formed. 30 is provided. The conventional mobile phone 10 is used to push up the receiver 20 for the transmission and reception of a call or message, it was provided with a sliding structure 40 for the sliding action in use.

As shown in FIG. 1B, the conventional sliding structure 40 disclosed in Korean Patent Laid-Open Publication No. 10-2005-0037649 includes a first slider member 41 and a first sliding member slidable to the first slider member 41. 2 slider members 42 were provided.

Here, the first slider member 41 includes a first magnetic force generating means 43, and the second slider member 42 includes a pair of second magnetic force generating means 44a and 44b, thereby providing a magnetic force. Was used to assist the sliding operation.

The conventional sliding structure 40 has a problem in that the sliding operation becomes difficult due to friction between the first slider member 41 and the second slider member 42 during the sliding operation often worsens the operation feeling. In particular, when the attractive force acts between the first magnetic force generating means 43 and the second magnetic force generating means 44a and 44b during the sliding operation, such a frictional force is further increased, so that a lot of operating force is required, so that the sliding action This is more difficult, there is a problem that the operation feeling becomes worse.

On the other hand, Fig. 1C shows another example of the sliding structure used in the conventional mobile phone. That is, in FIG. 1C, the sliding structure 50 disclosed in Korean Patent Laid-Open Publication No. 10-2005-0089584 is shown.

There was also a problem that could not be done.

In addition, the conventional sliding structure includes a sliding structure that slides in four directions, that is, a first slider member and a second slider member sliding in the vertical direction, and a second slider member and a third slider member sliding in the left and right directions. There was a sliding structure. However, the conventional four-way sliding structure has a problem that the thickness of the entire sliding structure is thick by simply placing two magnetic levitation module in the vertical direction.

In addition, in the conventional four-way sliding structure, an extension keypad is formed in the vertical direction on the second slider member sliding in the vertical direction, and a numeric keypad is formed in the left and right direction in the third slider member sliding in the left and right directions. . In this case, since the reading display directions of the extension keypad and the numeric keypad are formed in a direction perpendicular to each other, there is a problem in that when the user simultaneously uses the extension keypad and the numeric keypad, the numeric keypad should be viewed in the vertical direction.

On the other hand, the magnetic line shielding agent (140a) is disposed on the upper and lower surfaces of the first magnet portion 140.

Here, the magnetic force line shielding agent 140a according to the present embodiment is disposed only on the upper and lower surfaces of the first magnet part 140, but the present invention is not limited thereto. That is, the magnetic line shielding agent according to the present invention may be further disposed on the side surface of the first magnet part 140. In addition, the magnetic line shielding agent according to the present invention may not be directly disposed on the first magnet portion, but may be disposed on a part of the guide portion in which the first magnet portions are disposed. That is, in that case, first, the magnetic force line shielding agent is disposed at an appropriate position of a part of the guide portion, and then the first magnet portion is disposed on the guide portion.

In addition, the magnetic line shielding agent (140a) is made of a ferromagnetic material, to perform the function of shielding the magnetic line generated from the first magnet portion 140, AD-MU alloy may be used.

In addition, according to the present embodiment, the magnetic line shielding agent 140a is made of a ferromagnetic material, but the present invention is not limited thereto. That is, according to the present invention, the magnetic line shielding agent may be made of a nonmagnetic material.

Meanwhile, the pair of second magnet parts 151 and 152 are embedded in the first accommodating part 122.

Here, the magnets of the second magnet parts 151 and 152 of the present embodiment are all made of permanent magnets, but the present invention is not limited thereto. That is, the second magnet parts of the present invention can be applied to an electromagnet or the like in addition to the permanent magnet.

In addition, although the second magnet parts 151 and 152 of the present embodiment are embedded in the first accommodating part 122, the present invention is not limited thereto. That is, the second magnet parts according to the present invention may be arranged on the surface of the receiving portion.

That is, the second magnet parts 151 and 152 have a rectangular shape, and are disposed above and below the second accommodating part, respectively, and are disposed with the first magnet part 140 interposed therebetween, so that the first magnet part ( 140) and magnetic force interaction.

In addition, the second magnet parts 151 and 152 are arranged such that the arrangement forms of the magnetic poles are the same, while the arrangement direction of the respective magnet poles is arranged in a direction perpendicular to the sliding direction. That is, as shown in FIG. 4, the second magnet parts 151 and 152 are respectively disposed so that the upper side is the S pole and the lower side is the N pole.

The arrangement of the magnetic poles of the second magnet parts 151 and 152 as described above is opposite to the arrangement of the magnetic poles of the first magnet part 140. The reason is that the repulsive force is applied between the second magnet parts 151 and 152 and the first magnet part 140 to assist the sliding action.

In addition, the sliding structure 100 according to the present embodiment is characterized in that the length of the second magnet portion 151 and the second magnet portion 152 of the upper end is formed differently. In other words, the second magnet part 151 of the upper end may be formed to extend above the second guide part 124. On the contrary, the lower second magnet part 152 is formed to be shorter by the width of the second guide part 124 than the second magnet part 151 of the upper part due to the second guide part 124. The length difference between the second magnet part 151 at the top and the second magnet part 152 at the bottom is compensated by the fourth magnet part 171 to be described later.

The first magnet part 140 and the second magnet parts 151 and 152 are disposed so as to pass a part thereof. In such a configuration, the repulsive force always acts between the first magnet part 140 and the second magnet parts 151 and 152. Therefore, the second slider member 120 having the second magnet parts 151 and 152 may minimize friction during the sliding operation of the first slider member 110 having the first magnet part 140. This is because the second slider member 120 can be lifted from the first slider member 110 by the repulsive force. In that case, the degree of injury is related to the magnitude of the magnetic force acting, specifically the size and nature of the magnet to be applied.

In addition, according to the present exemplary embodiment, at least part of the first magnet part 140 may include a vertical virtual line connecting the surfaces of the second magnet parts 151 and 152 that face each other through the entire process of the sliding operation. Although the first magnet part 140 and the second magnet parts 151 and 152 are disposed to pass through, the present invention is not limited thereto. That is, according to the present invention, the vertical imaginary line connecting the mutually facing surfaces of the second magnet parts does not have to pass through the first magnet part. However, even in that case, it is desirable to configure the repulsive force to act between the first magnet portion and the second magnet portions by reducing the separation distance between the first magnet portion and the second magnet portions as much as possible, so as to reduce friction during sliding operation. Do.

On the other hand, magnetic line shields 153a and 153b are disposed on the bottom surface of the second magnet portion 151 and the top surface of the second magnet portion 152, respectively.

Since the material and function of the magnetic line shielding agent 153a and 153b are the same as those of the magnetic line shielding agent 140a described above, the description thereof will be omitted.

The magnetic line shields 153a and 153b according to the present exemplary embodiment are disposed only on the bottom surface of the second magnet portion 151 and the top surface of the second magnet portion 152, but the present invention is not limited thereto.

Can be arranged. In addition, the magnetic line shielding agent according to the present invention may not be disposed directly on the second magnet portion, but may be disposed on a portion of the accommodation portion in which the second magnet portions are accommodated. That is, in that case, first, the magnetic force line shielding agent is disposed at an appropriate position of a part of the accommodating portion, and then the second magnet portion is arranged in the accommodating portion.

Meanwhile, the third magnet part 160 is embedded in the second guide part 124 and disposed.

Here, the third magnet unit 160 of the present embodiment is made of one permanent magnet, but the present invention is not limited thereto. That is, the third magnet unit 160 of the present invention may be applied to an electromagnet or the like in addition to the permanent magnet.

In addition, although the third magnet part 160 of the present embodiment is embedded in the second guide part 124, the present invention is not limited thereto. That is, the third magnet part 160 according to the present invention may be disposed on the surface of the second guide part 124.

In addition, as shown in FIG. 2, the third magnet part 160 is disposed in a part corresponding to the middle part of the overall sliding stroke distance of the part of the second guide part 124 to assist the sliding action. It is composed.

In addition, the third magnet part 160 has a rectangular shape and is arranged such that the direction of arrangement of the magnet poles is perpendicular to the sliding direction. In the drawing, the arrangement of the magnet poles of the third magnet part 160 is arranged. The form is arrange | positioned so that an N pole may be upper and an S pole may be lower.

 In the present embodiment, the arrangement of the magnetic poles of the third magnet unit 160 is arranged such that the N pole is at the top and the S pole is at the bottom, but the present invention is not limited thereto. That is, according to the present invention, the arrangement of the magnetic poles of the third magnet unit 160 may be arranged such that the S pole is at the top and the N pole is at the bottom. In this case, however, it is preferable to change the arrangement of the magnetic poles of the corresponding fourth magnet portion in accordance with the arrangement of the magnetic poles of the third magnet portion to be changed.

On the other hand, the magnetic line shield 160a is disposed on the upper and lower surfaces of the third magnet unit 160. Since the material and the function of the magnetic line shielding agent 160a are the same as those of the magnetic line shielding agent 140a described above, a description thereof will be omitted.

Meanwhile, the pair of fourth magnet parts 171 and 172 are embedded in the second accommodating part 132.

Here, the magnets of the fourth magnet parts 171 and 172 of the present embodiment are all made of permanent magnets, but the present invention is not limited thereto. That is, the fourth magnet parts 171 and 172 of the present invention may be applied to an electromagnet or the like in addition to the permanent magnet.

In addition, although the fourth magnet parts 171 and 172 of the present embodiment are embedded in the second accommodating part 132, the present invention is not limited thereto. That is, the fourth magnet parts according to the present invention may be disposed on the surface of the receiving part.

That is, the fourth magnet parts 171 and 172 have a rectangular shape, and are respectively disposed above and below the second accommodating part 132, and are arranged with the third magnet part 160 interposed therebetween. It is configured to interact with the three magnet portion 160 and the magnetic force.

In addition, the fourth magnet parts 171 and 172 are arranged such that the arrangement directions of the magnetic poles are all the same, while the arrangement direction of the respective magnet poles is arranged in a direction perpendicular to the sliding direction. That is, as shown in FIG. 4, each of the fourth magnet parts 171 and 172 is disposed so that the upper side thereof is the S pole and the lower side thereof is the N pole.

The arrangement of the magnetic poles of the fourth magnet parts 171 and 172 as described above is opposite to the arrangement of the magnetic poles of the third magnet part 160. The reason is that the repulsive force is applied between the fourth magnet parts 171 and 172 and the third magnet part 160 to assist the sliding action.

In addition, the arrangement of the magnetic poles of the fourth magnet parts 171 and 172 may be the same as the arrangement of the magnetic poles of the second magnet parts 151 and 152. The reason for this is to compensate for the difference in length between the second magnet part 151 at the top and the second magnet part 152 at the bottom as described above. In other words, as shown in FIG. 2, the second magnet part 151 of the upper end formed in the first accommodating part 122 may be formed to the left end of the second slider member 120. On the contrary, the second magnet part 152 of the lower end formed on the second support part 121 is formed to have a shorter length than the second magnet part 151 of the upper part due to the second guide part 124. However, when the lengths of the upper and lower magnet portions are the same, a uniform magnetic force can be obtained and the sliding distance can be extended. Therefore, in the present invention, the arrangement of the magnetic poles of the fourth magnet part 171 is formed in the same manner as the arrangement of the magnetic poles of the second magnet part 152, so that the fourth magnet part 171 is the second magnet part. The role of 152 is also configured to perform at the same time.

By the above configuration, the sliding length of the third slider member 130 sliding with respect to the second slider member 120 may be extended. In addition, by extending the sliding length in this way, it is possible to obtain an effect that the usable space is expanded to increase the convenience of the user. In addition, since at least a part of the second magnet portion and the fourth magnet portion are arranged on the same plane, the thickness can be reduced as compared with the conventional four-way sliding structure.

In addition, according to the present exemplary embodiment, at least part of the third magnet part 160 includes a vertical virtual line connecting the surfaces of the fourth magnet parts 171 and 172 facing each other throughout the entire sliding operation. The third magnet part 160 and the fourth magnet parts 171 and 172 are disposed so as to pass through. In such a configuration, the repulsive force always acts between the third magnet part 160 and the fourth magnet parts 171 and 172. Accordingly, the friction of the third slider member 130 including the fourth magnet parts 171 and 172 may be minimized during the sliding operation of the second slider member 120 including the third magnet part 160. This is because the third slider member 130 can be lifted from the second slider member 120 by the repulsive force. In that case, the degree of injury is related to the magnitude of the magnetic force acting, specifically the size and nature of the magnet to be applied.

In addition, according to the present exemplary embodiment, a vertical virtual line connecting the surfaces of the fourth magnet parts 171 and 172 that face each other through the entire process of the sliding operation may include at least the third magnet part 160. The third magnet part 160 and the fourth magnet parts 171 and 172 are disposed to pass a part thereof, but the present invention is not limited thereto. That is, according to the present invention, the vertical virtual line connecting the surfaces of the fourth magnet parts 171 and 172 facing each other do not have to pass through the third magnet part 160. However, even in that case, the third magnet portion 160 and the fourth magnet portions 171 and 172 may be reduced by reducing the separation distance between the third magnet portion 160 and the fourth magnet portions 171 and 172 as much as possible. It is desirable to configure repulsive forces to act on each other in order to reduce friction in sliding operation.

On the other hand, magnetic line shields 173a and 173b are disposed on the bottom surface of the fourth magnet portion 171 and the top surface of the fourth magnet portion 172, respectively. Since the material and function of the magnetic line shield 173a and 173b are the same as those of the magnetic line shield 153a and 153b described above, the description thereof will be omitted.

As for the sliding structure 100 comprised as mentioned above, one of the 1st slider member 110, the 2nd slider member 120, and the 3rd slider member 130 is a portable electronic device, such as a mobile telephone, a camera, and a PMP. Electronic components such as a main chipset and a battery are mounted on a main body where concentration is concentrated, and the rest is mounted on a sub body having a relatively simple structure, thereby performing a sliding action.

In other words, as shown in FIG. 2, the first slider member 110 is mounted on the main body, the second slider member 120 is mounted on a circuit board, or the like, and the third slider member 130 is mounted on the button unit. It may be configured to be mounted to the sub body is formed.

In some cases, the main body is directly processed to form one of the first slider member 110, the second slider member 120, and the third slider member 130. It can also be formed by direct processing, in which case it is possible to reduce the volume required for installation, it is possible to implement a thin portable electronic device capable of sliding operation.

The sliding structure 100 according to the present invention discussed above, the first slider member 110 and the second slider member are provided with a first guide portion 112 and the first receiving portion 122 to be slidable in one direction. And a second slider member 120 and a third having a second guide part 124 and a third receiving part 133 so as to be able to slide in a direction substantially perpendicular to the sliding direction. Slider member 130 is characterized in that it is provided. In other words, as shown in FIG. 2, the first slider member 110 is configured to slide in the direction of an arrow A with respect to the second slider member 120. At the same time, the third slider member 130 is configured to slide in the direction of arrow B with respect to the second slider member 120.

By the above configuration, by providing a sliding structure that can extend in the vertical and horizontal directions of the electronic device, the available space of the user is expanded, there is an advantage that the electronic device capable of mounting a variety of expansion keypads and the like can be provided.

In addition, the sliding structure in the A direction and the sliding structure in the B direction is formed so that a portion thereof overlaps in a predetermined section, there is an advantage that can minimize the overall thickness of the sliding structure.

Hereinafter, the operation of the sliding structure 100 according to the present embodiment will be described with reference to the internal structure of the sliding structure 100 described above.

First, the sliding operation of the first slider member 110 and the second slider member 120 will be described.

3 is a diagram illustrating a case where the first slider member is in the initial position, FIG. 5 is a diagram illustrating a case where the first slider member is in the intermediate position, and FIG. 6 is a diagram in which the first slider member is in the final position. It is a figure which shows the case.

First, FIG. 3 is a diagram illustrating a case in which the first slider member 110 is in an initial position, and the first slider member 110 is positioned above the second slider member 120.

As shown in FIG. 3, a portion of the first magnet part 140 is positioned between the second magnet parts 151 and 152. In this case, between the second magnet parts 151 and 152 and the first magnet part 140 by the arrangement of the magnetic poles of the second magnet parts 151 and 152 and the first magnet part 140. Repulsive force will work.

In this case, the first slider member 110 can be stably disposed at the initial position by the acting repulsive force. In addition, the first slider member 110 rises to some extent from the second slider member 120 due to the acting repulsive force, thereby reducing the friction during the sliding operation.

When the user pushes the first slider member 110 upward in the state of FIG. 3, the entire portion of the first magnet part 140 is gradually positioned between the second magnet parts 151 and 152. . In this case, the repulsive force between the second magnet parts 151 and 152 and the first magnet part 140 gradually increases.

In this case, even if the user pushes up the first slider member 110 at a high speed, the repulsive force between the second magnet parts 151 and 152 and the first magnet part 140 is acted on, so that the first slider member is actuated. By preventing sudden movement of the 110, there is an effect of preventing the impact acting on the sliding structure (100). In addition, the first slider member 110 rises from the second slider member 120 due to the acting repulsive force, thereby reducing the friction during the sliding operation.

If the user continues to push the first slider member 110 upward, the sliding structure 100 reaches the state of FIG. 5.

FIG. 5 is a diagram illustrating a case in which the first slider member 110 is in an intermediate position, and most of the first magnet part 140 is positioned between the second magnet parts 151 and 152. The repulsive force acts strongly between the two magnet parts 151 and 152 and the first magnet part 140.

If the user continues to push up the first slider member 110 in the state of FIG. 5, the user may be driven by the repulsive force acting between the second magnet parts 151 and 152 and the first magnet part 140. The first slider member 110 can be pushed up with little or no force.

That is, in this case, since the user does not need to apply a special force to push up the first slider member 110, excessive impact on the sliding structure 100 can be prevented from being pushed up by the user. In addition, the first slider member 110 rises from the second slider member 120 by the acting repulsive force, thereby reducing the friction during the sliding operation.

If the user continues to push the first slider member 110 upward, the sliding structure 100 reaches the state of FIG. 6.

In the state of the sliding structure 100 of FIG. 6, the first magnet part 140 and the second magnet are arranged by the arrangement of the magnetic poles of the second magnet parts 151 and 152 and the first magnet part 140. The repulsive force acts between the parts 151 and 152.

In this case, the first slider member 110 can be stably disposed at the final position by the acting repulsive force. In addition, the first slider member 110 rises to some extent from the second slider member 120 due to the acting repulsive force, so that when the user later slides downward again, the friction can be reduced.

According to the present embodiment, only the case where the first slider member 110 is pushed up is described, but the present invention is not limited thereto. That is, according to the present invention, when pushing down the first slider member 110 positioned at the final position of FIG. 6, only the direction of the sliding operation described above is changed and applied as it is.

Next, the sliding operation of the third slider member 130 and the second slider member 120 will be described.

4 is a diagram illustrating a case where the third slider member is in the initial position, FIG. 7 is a diagram illustrating a case where the third slider member is in the intermediate position, and FIG. 8 is a diagram in which the third slider member is in the final position. It is a figure which shows the case.

First, FIG. 4 is a diagram illustrating a case where the third slider member 130 is in the initial position, and the third slider member 130 is positioned below the second slider member 120.

As shown in FIG. 4, a portion of the third magnet part 160 is positioned between the fourth magnet parts 171 and 172. In this case, between the fourth magnet parts 171 and 172 and the third magnet part 160 by the arrangement of the magnetic poles of the fourth magnet parts 171 and 172 and the third magnet part 160. Repulsive force will work.

In this case, the third slider member 130 can be stably disposed at the initial position by the acting repulsive force. In addition, since the third slider member 130 is spaced apart from the second slider member 120 to some extent by an acting repulsive force, it is possible to reduce friction during the later sliding operation.

When the user pushes the third slider member 130 to the right in the state of FIG. 4, the entire portion of the third magnet part 160 is gradually positioned between the fourth magnet parts 171 and 172. In this case, the repulsive force between the fourth magnet parts 171 and 172 and the third magnet part 160 is gradually increased.

In this case, even if the user pushes the third slider member 130 to the right at a high speed, the repulsive force between the fourth magnet parts 171 and 172 and the third magnet part 160 acts to cause the third slider to move. Since the sudden movement of the member 130 is prevented, there is an effect of preventing the impact acting on the sliding structure (100). In addition, the third slider member 130 is spaced apart from the second slider member 120 by the acting repulsive force, thereby reducing the friction during the sliding operation.

If the user continues to push the third slider member 130 to the right, the sliding structure 100 reaches the state of FIG. 7.

FIG. 7 is a diagram illustrating a case where the third slider member 130 is in an intermediate position. Most of the third magnet parts 160 are positioned between the fourth magnet parts 171 and 172. The repulsive force acts strongly between the four magnet parts 171 and 172 and the third magnet part 160.

When the user continuously pushes the third slider member 130 to the right in the state of FIG. 7, the user is driven by the repulsive force acting between the fourth magnet parts 171 and 172 and the third magnet part 160. The third slider member 130 can be pushed to the left side with little or no force.

That is, in this case, since the user does not need to apply special force to push the third slider member 130, not only the excessive impact on the sliding structure 100 can be prevented by the user's pushing force, In addition, the third slider member 130 is spaced apart from the second slider member 120 by the acting repulsive force, thereby reducing the friction during the sliding operation.

If the user continues to push the third slider member 130 to the right, the sliding structure 100 reaches the state of FIG. 8.

In the state of the sliding structure 100 of FIG. 8, the third magnet part 160 and the fourth magnet are arranged by the arrangement of the magnetic poles of the fourth magnet parts 171 and 172 and the third magnet part 160. Repulsive force is applied between the parts 171 and 172.

In this case, the third slider member 130 can be stably disposed at the final position by the acting repulsive force. In addition, since the third slider member 130 is spaced apart from the second slider member 120 to some extent by an acting repulsive force, when the user later slides downward again, the friction may be reduced.

According to the present embodiment, only the case where the third slider member 130 is pushed to the right has been described, but the present invention is not limited thereto. That is, according to the present invention, when the third slider member 130 positioned at the final position of FIG. 6 is pushed to the left side, only the direction of the sliding operation described above is changed and applied as it is.

As described above, the sliding structure 100 according to the present embodiment, by having the above structure, it is possible to prevent excessive impact that may occur during the sliding movement.

In addition, the structure of the sliding structure 100 according to the present embodiment, by directly processing the main body forms a structure of any one of the first slider member 110 or the second slider member 120, the other Since the structure can be easily formed by directly processing the sub-body, it is possible to reduce the volume required for installation, there is an advantage to implement a thin portable electronic device.

In addition, the sliding structure 100 according to the present embodiment, by having the structure as described above can be injured by the magnetic force, there is an advantage that can reduce the operation force by reducing the friction during the sliding operation.

9 is a view showing a state in which only the numeric keypad of the sliding structure according to the present embodiment is open, and FIG. 10 is a view showing a state in which the numeric keypad and the expansion keypad of the sliding structure according to the present embodiment are open.

In the present specification, a direction in which letters or numbers are displayed on the keypads 125 and 135 is defined as a 'readable display direction'. Here, the read display direction refers to a direction in which the user can read the keypad without rotating the sliding structure while the user is using the sliding structure. That is, as shown in FIG. 9, the read direction of the numeric keypad 135 is A direction. In addition, as shown in FIG. 10, the read direction of the numeric keypad 135 and the extended keypad 125 is the B direction.

Referring to FIG. 9, in the state in which only the numeric keypad 135 of the sliding structure 100 according to the present embodiment is opened, the read direction of the numeric keypad 135 becomes A direction. In other words, when the user uses the telephone function, that is, when only the third slider member 130 is drawn out and used with respect to the second slider member 120, the read direction of the numeric keypad 125 is secondly accommodated as in the related art. It is displayed in the direction parallel to the part 132.

Referring to FIG. 10, in the state in which the numeric keypad 135 and the expansion keypad 125 of the sliding structure 100 according to the present embodiment are opened together, readability of the numeric keypad 135 and the expansion keypad 125 is displayed. The direction becomes the B direction. In other words, when the user uses the keyboard function, that is, when both the first slider member 110 and the third slider member 130 are drawn out and used for the second slider member 120, the numeric keypad 135 and the expansion are used. The readability display direction of the keypad 125 is changed and displayed in a direction perpendicular to the second accommodating part 132.

In general, a keypad of an electronic device is placed on an elastic silicon pad or a contact pad to make a plurality of keys in an engraved, embossed or perforated form on a metal sheet or a plastic material. Then, the light emitted by the LED of the PCB board installed in the silicon pad or the contact pad bottom is transmitted so as to be transmitted to the upper portion of the silicon pad to be expressed toward the injection key. In the present invention, at least one LED corresponding to each key is formed, so that various numbers or menu buttons can be displayed in a horizontal or vertical direction on one key.

Here, one or more light sources, such as one or more LEDs, are disposed according to the direction of each key, and when the numeric keypad and the extended keypad are both used, the corresponding light sources are operated to be readable in the same direction and the input key value of the keypad is set. Since the light sources in the two directions emit light with respect to the keys assigned to the respective light paths, the user can easily check the changed state of the keypad according to each setting state.

However, the present invention is not limited thereto, and the keypad of the present invention may include a plurality of light emitting parts such as LEDs or ELs. Alternatively, one or more light emitting units assigned to one key may display various numbers in a horizontal or vertical direction. Alternatively, the individual buttons themselves may be mechanically rotated in the horizontal or vertical direction. In this case, it may be configured to rotate only the read direction by simply rotating while maintaining a unique key value, or may be configured to change the display direction of the screen because the entire numeric keypad is a single touch screen.

Meanwhile, the method of changing the readout display direction and arrangement of the numeric keypad 135 may be exemplified as follows.

First, only the read direction of each numeric keypad 135 may be changed. For example, in the state where only the numeric keypad 135 is opened, the "1" button is displayed in a direction parallel to the second receiving portion (see 132 in FIG. 2), and the numeric keypad 135 and the expansion keypad 125 are shown. ) Is opened together, the "1" button may be displayed in a direction perpendicular to the second receiving portion (see 132 of FIG. 2). In this case, each button always performs the same function, and only its display is changed in the horizontal or vertical direction. By such a configuration, the user can easily identify the keypad according to the use state of the electronic device.

Alternatively, the read direction and the arrangement of the numeric keypad 135 may be changed at the same time. For example, in FIG. 9, the "6" button displayed in a direction parallel to the second receiving portion (see 132 of FIG. 2) is in a direction perpendicular to the second receiving portion (see 132 of FIG. 2) in FIG. 10. The "1" button is displayed. That is, depending on whether only the numeric keypad 135 is opened or the numeric keypad 135 and the expansion keypad 125 are open together, the function and display of each button are changed together. By such a configuration, the user can easily identify the keypad according to the use state of the electronic device. Furthermore, the arrangement of the entire keypad of the electronic device may be similar to the layout of a keyboard of a general computer, and thus may have an effect of improving the user's convenience of operation.

On the other hand, in order for the read direction and arrangement of the numeric keypad 135 to be changed in this way, the change point should be sensed. In this case, various methods may be used to detect a change point of the read direction and arrangement of the numeric keypad 135.

First, when both the first slider member 110 and the third slider member 130 are opened, it is possible to detect a case where the numeric keypad 135 and the expansion keypad 125 are simultaneously open. To this end, a position sensor or a tact switch may be provided on at least one side of the first slider member 110, the second slider member 120, or the third slider member 130, or may be normally opened and closed by a permanent magnet. It may be provided with a sensing means. When both of the first slider member 110 and the third slider member 130 are opened, the open position sensor or the tact switch may sense the open position. This is based on the assumption that the case where the user opens both the first slider member 110 and the third slider member 130 is generally for character input.

Alternatively, you can take advantage of the automatic pivot feature. The automatic pivot function is a technology mainly used in the display field, and generally refers to a function in which the screen automatically stands up when the monitor is rotated. In the present invention, by applying this to the keypad, when the electronic device is erect in the longitudinal direction as shown in Figure 9 so that the numeric keypad is displayed in a direction parallel to the second receiving portion 132, in the horizontal direction as shown in FIG. In the case of standing upright, the numeric keypad may be displayed in a direction perpendicular to the second receiving portion 132. This automatic pivoting function is a conventionally commercialized technology, and detailed description thereof will be omitted herein.

Alternatively, the read direction and arrangement of the numeric keypad 135 may be changed manually. That is, a separate 'numeric keypad read display direction and arrangement type change button' is provided so that when the user wants to change the read display direction of the keypad or the user does not want to change the read display direction of the keypad, the readability of the keypad is displayed. When the change of direction is made, this button can be operated to change the readout direction and arrangement of the numeric keypad 135.

By the above configuration, when both the numeric keypad and the extended keypad are opened, the entire keypad arrangement is formed similarly to the keyboard arrangement of a general computer, so that the user's text input or document editing can be easily performed.

As described above, the sliding structure according to the present invention has the effect of realizing a thin portable electronic device, and also has an effect of improving the operation feeling by reducing the friction between each other during the sliding operation.

In addition, since the readout direction and arrangement of the numeric keypad are configured to be changeable, the operation convenience of the user may be improved.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
