Description

PORTABLE DEVICE WHICH HAS SLIDE AND ROTARY TYPE

DISPLAY MODULE

Technical Field

[1] The present invention relates to a portable device including a slide and a rotary type display module, and more particularly, to a portable device including a slide and a rotary type display module which includes display windows on front and rear surfaces of the display module so as to move and switch the display module front and rear with respect to a body, wherein the body prevents the display module from being shaked. Background Art

[2] Due to development of communication devices, portable devices in various structures have been introduced and currently, such portable devices are used by adding various functions such as MP3, DMB, or PDA to mobile phones.

[3] In order to perform such functions described above, the conventional portable devices should include a relatively large display window so as to represent various image inforamtion. However, the current portable devices having functions of mobile phones include various function buttons on a portion where a display window is to be located and thus, a size of the display window is limited.

[4] In addition, a portable multimedia player (PMP) which is one of the conventional portable device has a large screen (for example, 4.3" and 4.0") so that power consumption is greather than that of a small screen (for example, 2.2" and 2.0"). With regard to a MP3P function or a voice call function, the conventional PMP uses unnecessary "high-powered large screen" so that the time for using baterries is shortened and mobile communication terminals only use "low-powered small screens" so that extension of the use time and minimization of battery consumption are required.

[5] Moreover, since a user can separately purchases various kinds of the portable devices, such as, MP3P, DMB, PMP, PDA, PSP, UMPC, a navigation device, and a portable terminal, if necessary, there exists a waste of expenses due to the purchase and environmental pollution and waste of resources may occur.

[6] As not illustrated, the conventional portable device may be formed of a display module and a body, wherein the display module includes upper and lower display windows and wherein the body is fixed for both sides of one end of the display module to be rotated and includes an input unit. When the portable device is turned over, the display module may be damaged since the display module is separated from its original location due to self-weight while the display module is rotated and therby, inclines in a lower direction. [7] Also, in terms of visibility and functionality of products, a large screen (for example,

4.3" and 4.0") is suitable in PMP, a navigation device, UMPC, playing games, web- surfing, e-mailing and a small screen (for example, 2.2" and 2.0") is suitable in mobile phones, MP3P, and short messaging so that availability and convenience to use the portable devices are required.

[63] The portable device according to the current embodiment may form the front and rear display windows 102 and 104 in variable sizes and thus, allow the general voice calls, MP3P, and short messaging to be accomplished in the front display window 102 having a small screen (for example, 2.2" and 2.0" ) and PMP, an electronic dictionary, DMB watching, a navigation function, UMPC, gaming, web-surfing, and e-mailing to be accomplished in the rear display window 104 having a large screen (for example, 4.3" and 4.0").

[64] Also, according to the purpose of use, one or more front and rear display windows

102 and 104 may be selectively formed or one window may be fomred on a front surface or a rear surface.

[65] In addition, a function button which is an input unit may be added and installed to the front and rear display windows 102 and 104 or a touch screen may be employed, instead of installing the function button.

[66] Although not illustrated, an antenna for wireless communication or a stylus pen used on a touch screen may be installed to the display module 100 and the display module 100 may include a connector for connecting with a portable device connection supporter, that is separately prepared.

[67] Moreover, the display module 100 may include a slot (not illustrated) for changing a card-type module, to which functions of wireless internet, MP3, mobile phones, playstation, DMB, PMP, PDA displaying information, UMPC, electronic dictionary, or a navigation device is added, into a specific module and for adding, deleting, or upgrading functions.

[68] Although not illustrated, a camera (not illustrated) may be installed in the display module 100 or the body 200, in roder to perform video chatting, video conversation, or video communication through Internet while web-surfing.

[69] The camera is hidden and fixed between the front and rear display windows while the camera is not in use. When the camera is in use, the camera may be slided and moved so as to be exposed to the outside the display module 100 or the camera may be rotated based on a rotation axis member so as to be exposed to the outside the display module 100.

[70] The camera may be an internal type as in installing in the conventional portable device or installed in a rotation type or a vertical landing slide type, thereby facilitating capturing targets. Here, a location of the camera being installed or an installation structure is not particularly restricted.

[71] In the body 200, a combination groove 202, to which the display module 100 is disposed and combined, is receded and side walls 204 are projected to form opposed surfaces corresponding to the side surfaces of the display module 100 and facing each other. In other words, two surfaces are projected toward the upper part (upward direction) so that the sied walls 204 that are parallel to each other are formed and the combination groove 202, to which the display module 100 is disposed and combined, is formed between the side walls 204.

[72] A slider groove 206 is formed at the center part in the opposed surfaces of inside the side walls 204 along a longitudinal direction and a fixing member 210 is inserted into the slider groove 206. Although not illustrated, the slider groove 206 may be formed on the side 110 of the display module 100. The slider groove 206 is closed using completion members 208 disposed both ends of the slider groove 206 and the front part of the slider groove 206 which is opened is closed by a cover member 220.

[73] A battery (not illustrated) is included in the back of the body 200 and a function button, which is an input unit, may be further included on the upper surface of the side wall 204.

[74] A keyboard type input unit 202a displosed on the bottom surface of the combination groove 202 is formed in a single body type, a cover type, or a sliding type and may be separated from the body 200.

[75] The input unit 202a includes the slot (not illustrated) on the lower part thereof so as to change a card-type module, to which functions of wireless internet, MP3, mobile phones, playstation, DMB, PMP, PDA displaying information, UMPC, electronic dictionary, or a navigation device is added, into a specific module and to add, delete, or upgrade functions.

[76] The fixing member 210 is in a block form with a size suitable to be inserted and fixed into the inside the slider groove 206 and includes a stepped up portion on the side of the fixing member 210. A plurality of projections 210a is projected on the bottom of the stepped up side in a uniform or non-uniform interval. In correspondence with a rotating axis 500 of the display module 100, a hump 214 having an angle corresponding to a rotating angle of the display module 100 is formed on one end of the side wall of the stepped up side. An installation groove member 212 is formed at the rear of the hump 214 so as for a restoring force generation unit 330, which will be described later, to be installed. A rotation guide groove 216 is rounded and formed in a round shape on the bottom of the stepped up side disposed at the front of the hump 214 so as for an interlocking member 320, which will be described later, to be rotated and located on the rotation guide groove 216.

[77] Although not illustrated, the hump 214, the installation groove member 212, and the rotation guide groove 216 may be installed to both ends of the side wall of the stepped up side of the fixing member 210.

[78] The cover member 220 closes the slider groove 206 opened in the opposed surfaces of inside the side wall 204 included in the body 200 and a slit formed moving hole 222 is extended along the center part of the cover member 220 in a longitudinal direction.

[79] The display module 100 slides and moves along the moving hole 222 and a round- shape rotation axis hole 224 is formed on an end of the moving hole 222 which corresponds to the hump 214 so as for the display module 100 to be easily rotated based on the rotating axis 500.

[80] A stopper hole 226 is formed to be adjacent to the rotation axis hole 224 of the cover member 220 and is used as an appearing path of a stopper 400, which will be described later in correspondence to the movement guide hole 112.

[81] The connection means may include a slider 310, the interlocking member 320, and the restoring force generation unit 330.

[82] The one end of the slider 310 is fixed to the display module 100, in correspondence to the rotating axis 500 and other end of the slider 310 is inserted into the slider groove 206 so that slider 310 allows the display module 100 to be slide moved or rotated along the side wall 204 of the body 200. A path 318 is penetrated and formed in the slider 310 in a longitudianl direction so as to facilitate elelctrical connection between the display module 100 and the body 200.

[83] The slider 310 is formed of a combining member 312, a parallel member 314, an orthogonal member 316, and a combining unit 317, wherein the combining member 312 is fixed inside the display module 100, the parallel member 314 is projected toward the side wall 204 of the body 200 from one side of the combining member, the orthogonal member 316, which is in a squre filler form, formed perpendicular to the combining member 312 and the parallel member 314 from the rear end of the parallel member 314, and the combining unit 317 is projected and formed on an extension of the parallel member at the rear end of the orthogonal member 316. The slider 310 may correspond to the slider groove 206 and may be formed on the side 110 of the display module 100 or the side wall 204 of the body 200.

[84] One side of both sides of the orthogonal member 316 in a longitudinal direction is rounded so as to facilitate rotating and corresponds to the projection 210a so as to form a groove 316a on the upper section or the lower section of the orthogonal member 316. Here, the projection 210a may be formed on the orthogonal member 316 and the groove 316a may be formed on the fixing member 210.

[85] The interlocking member 320 corresponds to the hump 214 of the fixing member 210 and is located on the rotation guide groove 216. The interlocking member 320 is combined to be able to rotate based on the rotating axis 500 by the rotation guide groove 216. The interlocking member 320 is formed on one end of a stepped up cylinder so as for the combining unit 317 of the slider 310 to be combined and includes a stepped up groove 322 and at least one angle limiting groove 324, wherein the stepped up groove 322 closes the outside the interlocking member 320 so as to limit a moving distance of the parallel member 314 and wherein the angle limiting groove 324 is combined to the hump 214 of the fixing member 210 at the rear surface opposite to the stepped up groove 322 and is formed based on the rotating axis 500 according to a rotating angle of the display module 100 so as to limit an angle.

[86] A part of the stepped up groove 322 may be closed using a prevention hump 322a which prevents the parallel member 314 from moving downward and according to the function of the prevention hump 322a, the display module 100 may be stopped, instead of being moved downward.

[87] One side of the interlocking member 320, to which the stepped up groove 322 is formed, may be spaced apart from the rotation guide groove 216 so as to not interfere wires extended through a path of the slider 310, when the combining unit 317 is inserted into the stepped up groove 322 and the interlocking member 320 is rotated.

[88] Both end sections of the interlocking member 320 according to a direction of the rotating axis 500 are supported within the rotation guide groove 216 and prevent the interlocking member 320 from being moved while the interlocking member 320 is rotated.

[89] The inlet of the angle limiting groove 324 is formed to be rounded so as to facilite separating from the hump 214 of the fixing member 210.

[90] In other words, the interlocking member 320 includes one or more angle limiting grooves 324 at the rear of the interlocking member 320, each of the angle limiting grooves 324 being formed differently according to a rotating angle of the display module 100, in a form corresponding to the hump 214 of the fixing member 210. The one or more angle limiting grooves 324 may be formed in all directions so as to change an angle of the display module 100 to 30°, 45°, 50°,60°, 70°, 80°, and 90°starting from 0°.

[91] Here, the angle limiting grooves 324 may be formed on the fixing member 210 and the hump 214 may be formed on the interlocking member 320.

[92] The restoring force generation unit 330 is connected to the center of the interlocking member 320 and thus, the interlocking member 320 is rotated while the slider 310 is rotated, so that the restoring force generation unit 330 allows the hump 214 and the angle limiting groove 324 to be eaily combined to each other by a restoring force, wherein the restoring force generation unit 330 is formed of a bolt 332, a nut 334, and an elastic member 336.

[93] The bolt 332 includes a square piller bolt head 332a so as to not idle while the bolt

332 is combined to the center of the interlocking member 320. A bolt pillar 332b is extended from the bolt head 332a and to inside an interval member 338. A spiral pillar 332c is extended from the bolt pillar 332b and penetrates the interval member 338, which parallel moves by a distance corresponding to the hump 214 in the installation groove member 212 formed at the rear of the fixing member 210.

[94] The nut 334 is fixed to the spiral pillar 332c of the bolt 332 which is exposed to the interval member 338 and the nut 334 may be the interval member 338.

[95] The elastic member 336 is formed to surround the bolt pillar 332b in the installation groove member 212 and obtains an elasticity restoring force.

[96] The stopper 400 allows the display module 100 not to be shaken up and down and to be slide moved maintaining a horizontal state with the body 200 and prevents the display module 100 from being lifted upward by force (that is the display module 10 from being rotated) due to the own weight, when the display modile 100 is combined to the body 200. According to the slide movement of the display module 100, the stopper 400 appears from the stopper hole 226 and is inserted into or separated from the movement guide hole 112. The stopper 400 is formed of an appearing member 410 and an elastic member 420.

[97] The appearing member 410 is formed of the tip 411, a rear end 415, and a round shape projection 417, wherein the appearing member 410 has an oval shape since a side 413 of the tip 411 formed to be rounded, the rear end 415 is formed to be larger than the stopper hole 226 installed to the cover member 220 so as to not separated, and the round shape projection 417 is disposed on the back surface of the rear end 415.

[98] In the round shape projection 417, the elastic member 420 is inserted and fixed.

[99] In the portable device described above, the display module 100 is combined so as to be rotated at the side wall 204 of the body 200 based on the rotating axis 500 or to be slide moved along the side wall 204.

[100] More specifically, the combining member 312 of the slider 310 is inserted into and fixed to the display module 100 based on the rotating axis 500 so as for the slider 310 is projected from the side wall 204 of the display module 100, the parallel member 314 of the slider 310 is installed so as to be slide moved in the moving hole 222, and the orthogonal member 316 is interposed between the fixing member 210 and the cover member 220.

[101] Here, the parallel member 314 may be formed in a squre filler shape so as for the moving hole 222 to not rotated in the moving hole 222.

[102] The interlocking member 320 is located on the rotation guide groove 216 of the fixing member 210 and is combined to the fixing member 210 by the restoring force generation unit 330 so as to be rotated.

[103] The fixing member 210 to which the interlocking member 320 is combined is inserted and fixed to the slider groove 206 and the slider groove 206 is closed using the completion members 208 and the cover member 220.

[104] Then, the display module 100 is slide moved along the moving hole 222 and is rotatable by 180°through the connection means in the rotating axis 500 so that the front and rear display widows 102 and 104 such as LCD is respectively disposed on the front surface and the rear surface of the display module 100 and thus, the front surface and the rear surface may be selectively used.

[105] Hereinafter, the operation of the portable device is described.

[106] FIGS. 5 and 6 are cross sectional views illustrating when the display module 100 in the portable device is respectively rotated by 0 and 180°and FIGS. 7 and 8 are side views illustrating the display module being rotated in the portable device.

[107] Referring to FIGS. 5 through 8, the portable device according to the current embodiment moves in front and in the rear in a parallel direction while the tips of the slider 310 are respectively fixed to inside the both surfaces of the display module 100 and the rear end of the slider 310 is disposed inside the slider groove 206 of the body 200.

[108] At the same time, the parallel member 314 of the slider 310 slide moves along the moving hole 222 so as to reach the rotating axis 500 and the appearing member 410 of the stopper 400 is inserted into the movement guide hole 112 so as to be slide moved.

[109] When the combining unit 317 of the slider 310 is inserted into and combined to the stepped up groove 322 of the interlocking member 320 at the rotating axis 500, the appearing member 410 is separated from the movement guide hole 112.

[110] When the display module 100 is rotated, the appearing member 410 of the stopper 400 stays as it is pressed.

[I l l] Although not illustrated, when the combining unit 317 of the slider 310 is inserted into and combined to the stepped up groove 322 of the interlocking member 320 at the rotating axis 500, the appearing member 410 stays as it is inserted into the movement guide hole 112. Also, when the display module 100 is rotated, the appearing member 410 of the stopper 400 is separated from the movement guide hole 112 due to round- shaped tip and when the display module 100 is rotated by 180 degrees, the appearing member 410 is inserted again into the movement guide hole 112.

[112] Ultimately, the stopeer 400 disposed between the side walls 204 of the body

200, which face the movement guide hole 112 of the display module 100, prevents the display module 100 from being rotated by force due to the own weight, while the display module 100 is combined to the body 200.

[113] The orthogonal member 316 is disposed inside the moving hole 222 of the cover member 220 (that is, the inside the slider groove 206) and thus, is not separated from the moving hole 222, while the slider 310 is moved.

[114] When the angle limiting groove 324 engages with the hump 214, while the display module 100 is rotated, the elastic member 336 is not yet pressurized and when the angle limiting groove 324 is separated from the hump 214, the elastic member 336 is pressurized between the installation groove member 212 and the interval member 338 so that the interlocking member 320 is affected by an elasticity restoring force from the elastic member 336.

[115] That is, when the slider 310 and the interlocking member 320 is combined to each other, in order to rotate the display module 100, the display module 100 may be roated by a set angle and when the rotating angle limiting groove 324 engages with the hump 214, the angle limiting groove 324 is inserted into the hump 214 by an elasticity restoring force and thereby, the location of the display module 100 is fixed. Also, when the angle limiting groove 324 is separated from the hump 214 by an external force, an applied force of the interlocking member 320 is applied to a direction of the hump 214.

[116] Then, the front and rear display windows 102 and 104 stand so that information displying on the display window may be read from an angle that is convenient for a user (for example: any angle selected by a user such as 30°, 45°, 50°,60°, 70°, 80°, and 90°). In other words, since the upper and lower display windows 102 and 104 are rotated by a predetermined angle selected by a user, a visual field for viewing the front and rear display windows 102 and 104 is secured by a user and thereby, providing convenience.

[117] More specifically, information needed to perform a function of a mobile phone, a MP3 player, and text messages may be displayed on the front display window 102. Also, in order to display images or information needed to perform functions such as internet surfing, watching DMB broadcasting, PMP or PDA for watching movies stored in a memory, an electronic dictionary, game, a navigation device, and UMPC by rotating the rear display window 104 upward, the display module 100 may be rotated by 180 degrees.

[118] When the display window 100 is slide moved to the end of the moving hole 222 so as for the display module 100 is located on the combination groove 202 of the body 200, while the front display window 102 faces upward and the display module 100 is rotated by 180 degrees based on the rotating axis 500 so as to make parallel with the body 200, the rear display window 104 is exposed upside and thus, information displaying on the lower display window 104 may be used.

[119] On the other hand, when the display module 100 is slide moved to the forefront and then, is rotated by 180 degrees based on the rotating axis 500, in order to make the rear display window 104 face downward, the rear display window 104 is turned over and the front display window 102 is exposed upside so that information displaying on the front display window 102 may be used.

[120] Here, when the interlocking member 320 and the restoring force generation unit 330 are combined to each other at the both sides of the fixing member 210, the display module 100 may be easily turned over.

[121] In this case, the moving location of the slider 310, that is fixed to the display module 100, is limited in each interval by the projection 210a and the plurality of grooves 316a having a uniform or non-uniform interval respectively formed on the inside bottom of the fixing member 210 and the orthogonal member 316 so as to temporarily stop the display module 100 from moving. Mode for the Invention

[122] In describing various embodiments, like reference numerals denote like elements in the above embodiment and other elements that are different from the above embodiment are described below.

[123] A portable device according to another embodiment is now described.

[124] FIG. 9 is an exploded perspective view partially illustrating the portable device and FIG. 10 is a cross sectional view of the portabl device being combined.

[125] Referring to FIGS. 9 and 10, the portable device according to the current embodiment includes the display module 100, the body 200, the connection means, and the stopper 400. Hereinafter, the fixing member 210, the slider 310, and the restoring force generation unit 330 which are distinguished from those of the above embodiment are described. [126] In the fixing member 210 incldued in the slider groove 206 of the body 200, an axis member location hole 230, to which an axis member 331 of the restoring force generation unit 330 is inserted is penetrated, and an axis member groove 231 is formed inside the axis member location hole 230.

[127] The slider 310 is formed of the combining member 312, the square piller shape parallel member 314, and the cylinder shape orthogonal member 316, wherein the combining member 312 is fixed inside the display module 100, the parallel member 314 is projected toward the side wall 204 of the body 200 from one side of the combining member 312, and the orthogonal member 316 is formed perpendicular to the parallel member 314 from the rear of the parallel member 314 and includes the combining unit 317 projected from the rear of the orthogonal member 316.

[128] The cylinder shape orthogonal member 316 corresponds to the projection 210a and the grooves 316a are formed along the circumference of the orthogonal member 316. Here, the projection 210a may be formed on the orthogonal member 316 and the grooves 316a may be formed on the fixing member 210.

[129] The one side of the interlocking member 320, on which the stepped up groove 322 is formed, may be spaced apart from the rotation guide groove 216, in order to not interfere with wires extended through a path of the slider 310, when the combining unit 317 of the slider 310 is inserted into the stepped up groove 322 and thus, the interlocking member 320 is rotated.

[130] Also, the both ends of the interlocking member 320 according to the direction of the rotating axis 500 are supported in the rotation guide groove 216 and are prevented from moving, when the interlocking member 320 is rotated.

[131] The restoring force generation unit 330 is formed of the axis member 331 and the elastic member 336.

[132] The axis member 331 is inserted into the axis member location hole 230 at a straight line with the rotation guide groove 216. The axis member 331 includes the hump 214 and an elastic member inserting groove 335 respectively on the front surface and the rear surface of the axis member 331. The elastic member 336 is disposed in the elastic member inserting groove 335.

[133] Here, the hump 214 of the axis member 331 may be only projected toward the interlocking member 320 in the axis member location hole 230 and thus, the axis member 331 may be moved back and forth along the axis member location hole 230 by an elastic force of the elastic member 336.

[134] A fixing tip 333 which is inserted into the axis member groove 231 is formed outer surface of the axis member 331 and thus, prevents the axis member 331 from moving.

[135] Although not illustrated, the axis member 331 is formed in an angular piller and is inserted into the axis member location hole 230, thereby preventing the axis member 331 from rotating.

[136] Hereinafter, the operation of the portable device is described. [137] In the portable device according to the current embodiement, the axis member 331, which is inserted into the axis member location hole 230, always generates push force by the elastic member 336 to a directio of the interlocking member 320. [138] The combining unit 317 of the slider 310 that is interlocked when the display module

100 is rotated may be combined to the interlocking member 320 and interlocked. When the angle limiting groove 324 of the interlocked interlocking member 320 is located on and combined to the hump 214 of the axis member 331 by the elasticity restoring force, an rotating angle of the display module 100 is fixed. [139] Then, wheh the display module 100 is rotated by force for changing an angle, the angle limiting groove 324 of the interlocking member 320 is separated from the hump

214 of the axis member 331 so that the display module 100 may be rotated by a change angle or to an initial location.

[140] Hereinafter, a portable device accoridng to another embodiment is described. [141] FIG. 11 is an exploded perspective view partially illustrating the portable device;

FIG. 12 partially illustrates a body of the portable device; and FIG. 13 illustrates the portable device being combined . [142] Referring to FIGS. 11 through 13, the portable device according to the current embodiment includes the display module 100, the body 200, the connection means, and the stopper 400. [143] When the slider grooves 206 are formed, the side wall 204 of the body 200 may be divided into an upper side wall 204a and a lower side wall 204b based on the moving hole 222 formed for the slider 310 to be slide moved. [144] Then, a member combining means 319 is formed on the surface to which the upper side wall 204a and the lower side wall 204b face each other so that the upper side wall

204a and the lower side wall 204b are combined as a single body by the member combining means 319. Thus, the display module 100 may be easily installed to the body 200 and the display module 100 may be easily slide moved and rotated with resepct to the body 200. [145] Any one of the upper side wall 204a and the lower side wall 204b is formed as a single body with the body 200. In the drawing, the lower side wall 204b and the body

200 are formed as a single body. [146] Although not illustrated, when the upper side wall 204a and the body 200 are formed as a single body, the cover member 220 may not be divided into two in order to connect the upper side wall 204a with the body 200. [147] As illustrated, since the member combining means 319 is formed of a projection and a groove corresponding to the projection, the projection is inserted into the groove using a forced-inserting method and thus, the upper side wall 204a and the lower side wall 204b are combined to each other.

[148] A well known technology may be applied to the member combining means 319 so as to combine members separated upper and lower sides as a single body.

[149] Since the side wall 204 of the body 200 is divided into two, the cover member 220 may be divided into a upper cover member 220a and a lower cover member 220b respectively in correspondence to the upper side wall 204a and the lower side wall 204b, and thus, the upper cover member 220a and the lower cover member 220b are formed in a single body on the opened slider groove 206, as illustrated in FIG. 11.

[150] The moving hole 222 and the rotation axis hole 224 formed on the cover member 220 may be also divided so that an upper moving hole 222a and a upper rotating axis hole 224a may be formed on the upper cover member 220a and a lower moving hole 222b and a lower rotating axis hole 224b may be formed on the lower cover member 220b.

[151] In addition, since the side wall 204 of the body 200 is divided into two, the fixing member 210 according to the first described embodiment and the previous embodiment is formed as a single body on the slider groove 206 that is formed on the lower side wall 204b.

[152] In the drawing, the fixing member 210 according to the previous embodiment is formed as a single body.

[153] The one side of the interlocking member 320, on which the stepped up groove 322 is formed, may be spaced apart from the rotation guide groove 216, in order to not interfere with wires extended through a path of the slider 310, when the combining unit 317 of the slider 310 is inserted into the stepped up groove 322 and thus, the interlocking member 320 is rotated.

[154] Also, the both ends of the interlocking member 320 according to the direction of the rotating axis 500 are supported in the rotation guide groove 216 and are prevented from moving, when the interlocking member 320 is rotated.

[155] A wire path 218 is receded on the bottom of the stepped up side of the fixing member 210 to correspond to the path 318, which penetrates the stepped up groove 32 of the interlocking member 320 and the combining unit 317 of the slider 310, along a direction of the display module 100 be slided.

[156] The wire path 218 allows a wire connecting the circuit board 106 and a battery (not illustrated) to stably flow according to movement of the slider 310. The wire path 218 may be receded in a hexahedron form with the opened upper part on the bottom of the stepped up side of the fixing member 210.

[157] A shield coating material is applied to the inside the wire path 218 and a connection hole 218a may penetrate the wire path 218 so that the wire connected with the circuit board 106 may be eailsy connected to the battery and noise occuring due to the wire may be removed.

[158] Also, the end part of the combining unit 317 is inserted into the side wall of the stepped up side of the fixing member 210 in correspondence to the combining unit 317 of the slider 310 and thus, a guide groove 219 may be formed for slide moving. Then, the slider 310 is prevented from moving. The side wall of the stepped up side of the fixing member 210 may have a sufficient thickness.

[159] In addition, the fixing member 210 according to the current embodiment may be formed on the upper side wall 204a as a single body.

[160] When the restoring force generation unit 330 according to the above embodiment is formed, an elastic supporting pole 337 which is surrounded by the elastic member 336 and is inserted into the elastic member inserting groove 335 of the axis member 331 may be projected and formed on the axis member groove 231.

[161] A fixing projection 228 is projected and formed on any one of the upper side wall 204a and the lower side wall 204b (that is, the cover member 200) in correspondence to the side 110 of the display module 100. Thus, when the display module 100 is located on and combined to the combination groove 202 of the body 200 and the portable device is turned over, the display module 100 may be prevented from being moved by the own weight.

[162] As illustrated in FIG. 11, the fixing projection 228 is formed along with the stopper 400 and is formed on the end part of the moving hole 222 on which the rotation axis hole 224 is not formed. Here, although not illustrated, a fixing groove (not illustrated) may be formed on the side 110 of the display module 100, in correspondence to the fixing projection 228. The one side of the fixing projection 228 forms a free end and thus, is flexible. According to the operation of the display module 100, the fixing projection 228 is inserted into or separated from the fixing groove (not illustrated).

[163] A rib may be projected toward the fixing groove (not illustrated) from the section of the free end. As illustrated, the rib has a hemisphere form and is easily inserted into or separated from the fixing groove (not illustrated) according to the operation of the display module 100.

[164] The fixing projection 228 may be formed on the display module 100 and the fixing groove (not illustrated) may be formed on the side wall 204 of the body 200, that is, the cover member 220.

[165] As in the fixing projection 228, the projection 210a forms a free end at the one side and thus, is flexible so that the projection 210a is inserted into or separated from the groove 316a of the slider 310 according to the operation of the display module 110.

[166] Here, the both sides of the free end of the projection 210a are extended to the both side walls guiding the orthogonal member 316 and thereby, a flowing groove 210b is formed on the both side walls guiding the orthogonal member 316 so that the free end of the projection 210a is limited from moving by an elastic force. [167] Then, overaction of the projection 210a may be prevented and thereby, the projection

210a may be prevented from being damaged. [168] A rotating groove 203 is receded and formed in the combination groove 202 of the body 200, in correspondence to the rotating axis 500 of the display module 100 and thus, allows the display module 100 to not interfered with the combination groove 202 of the body 200 and to be smoothly moved based on the rotating axis 500. [169] The slider 310 may be divided into an upper slider 310a and a lower slider 310b based on the path 318. [170] ALso, the parallel member 314 of the slider 310 forms a stepped up part in cor- respondene to the cover member 220 so as to surround the moving hole 222 contacted by the parallel member 314. [171] Then, the display module 100 may be stably slide moved along the moving hole 222 by the stepped up parallel member 314. [172] Any one of the upper slider 310a and the lower slider 310b may be formed as a single body on the display module 100. [173] Since the member combining means 319 is formed on the surface to which the upper slider 310a and the lower slider 310b face along the the edge of the path 318, the upper slider 310a and the lower slider 310b are combined to each other as a single body by the member combining means 319 and thus, the wire may be easily installed through the path 318. [174] As described above, the member combining means 319 is formed of the projection and the groove corresponding to the projection and the projecton is inserted into the groove using a forced-inserting method and thus, the upper slider 310a and the lower slider 310b are combined to each other. [175] The portable device according to the current embodiment may be operated in the same manner as in the portable device according to the first embodiment or the previous embodiment.

[176] Hereinafter, a portable device accoridng to another embodiment is described. [177] FIG. 14 is illustrates the portable device being combined according to another embodiment of the present invention. [178] Referring to FIG. 14, in the portable device according to the current embodiment, location of the the axis member location hole 230 in the portable device according to the previous embodiment is changed so that a width of the side wall 204 is reduced and size of the portable device may be reduced. [179] According to the current embodiment, the axis member location hole 230 is disposed on the side of the rotation guide groove 216. Also, the plurality of angle limiting grooves 324 is formed on the edge of the interlocking member 320 in correspondence to the hump 214 of the axis member 331 located on the axis member location hole 230.

[180] The angle limiting grooves 324 is formed along the edge of the interlocking member 320 in correspondence to rotation of the display module 100.

[181] Then, the restoring force generation unit 330, which moves back and forth according to rotation of the display module 100, moves in a direction perpendicular to the rotating axis 500.

[182] Here, the fixing tip 333 may not be formed on the axis member 331.
