     The interface  116  serves as a path which allows the terminal  100  to exchange data with external devices. For example, the interface  116  may be used in a wired or wireless manner, and may be at least one of a connection terminal to which an earphone is connected, a power supply terminal for supplying power to the terminal  100 , or a port for local communication, such as an infrared data (IrDA) port, a Bluetooth port or a wireless LAN port. Alternatively, the interface  116  may be a card socket for receiving an external card such as a Subscriber Identification Module (SIM), a User Identity Module (UIM), or a memory card for storing information. 
     The second body  120  may include second and third input interfaces  123 ,  124 , and a sound input unit  125 , as shown in  FIG. 4 . The first to third input interfaces  115 ,  123 ,  124  may be referred to as an input unit which are manipulated by a user in a tactile manner. 
     For example, the input units  115 ,  123 ,  124  may be implemented as a dome switch, a touch screen or a touch pad and the user may input commands or information by pushing or touching the input units. Alternatively, the input units may be implemented as a wheel, a jog, or a joystick. 
     Further, the first input interface  115  may be configured to input commands, such as start, end, or scroll, and the second input interface  123  may be configured to input figures, letters, or symbols. Furthermore, the third input interface  124  may be used as a hot key to perform a specific function, such as activating an image input unit  128 . The sound input unit  125  may be a microphone to receive the user&#39;s voice or other external sound. 
     Referring to  FIG. 3 , the image input unit  128  may be located at a rear surface of the first body  110 . The image input unit  128  may be a camera module for capturing still images or moving images. A flashlight  129  and a reflective surface  130  may be additionally disposed near the image input unit  128 . When photographing a subject through the image input unit  128 , the flashlight  129  flashes light on the subject. When the user photographs a self-portrait through the image input unit  128 , the user may look at himself/herself on the reflective surface  130 . 
     A recess portion  118  is formed at a lateral surface of the rear case  112  of the first body  110 , the lateral surface siding with a rear surface of the rear case. When the second body  120  moves with respect to the first body  110 , the second body slides over the recess portion  118  of the rear case  112 . As shown in  FIG. 3 , the upper portion of the rear surface of the rear case  112  may be protruded compared to the rest of the rear surface of the rear case such that the surface of the protruded upper portion of the rear case is level with a surface of a battery cover  127  in the closed configuration. Alternatively, the rear surface of the rear case  112  of the first body  110  may be a single flat surface such that the rear surface of the rear case is entirely covered by the battery cover in the closed configuration. The battery cover  127  for covering a battery, which supplies power to the mobile terminal  100 , may be detachably mounted at a rear surface of the second body  120 . 
     Referring to  FIG. 4 , a slide module  140  couples the first and second bodies  110 ,  120  in a sliding manner. The slide module  140  includes a first slide member  141  and a second slide member  142  slidably coupled to the first slide member. The first and second slide members  141 ,  142  may be formed of a metallic material such as stainless steel (STS) or titanium (Ti). 
     The first slide member  141  is mounted in the first body  110 , specifically, between the front case  111  and the rear case  112  of the first body. A display module  143 , a touch sensor  144 , and a printed circuit board  145  may be fixed at the first slide member  141 . 
     A window  117  provided with a light translucent area may be mounted at the front case  111 , and the display module  143  for displaying visual information through the window  117  is mounted at the front surface of the first slide member  141 . A plurality of touch sensors  144  for sensing a touch input via the first input interface  115  may be disposed on a circuit board  146  located below the display module  143  on the first slide member. The plurality of touch sensors  144  may be arranged in a pattern such that each of the plurality of touch sensors is placed separately from each other. The circuit board  146 , on which the plurality of touch sensors  144  are fixed, is mounted on the first slide member  141 . 
     In an embodiment of the present invention, the first input interface  115  is manipulated by touching. Further, the first input interface  115  may be implemented as a keypad or switches on the first slide member  141  and manipulated by pressing. A sound output unit  147  for outputting sounds may be mounted on the first slide member  141  above the display module  143 . 
     The printed circuit board  145 , which is mounted at a rear surface of the first slide member  141 , is provided with electronic components for operating various functions of the mobile terminal  100 . For example, the electronic components of the printed circuit board  145  may include a controller for controlling the operation of the terminal  100  and a camera module for inputting images. 
     A pair of opposite facing slide rails  148  are formed at the second slide member  142  along the length of the first body  110 , and a pair of opposite side edges of the first slide member  141  are inserted into the pair of slide rails such that the first slide member moves along the pair of slide rails. The second input interface  123 , which is mounted at the front surface of the second slide member  142 , may be implemented as a keypad assembly and information may be input by pressing the keypad. Alternatively, the second input interface  123  may be a touch screen and information may be input by touching the touch screen. A microphone  149  for inputting sounds may be mounted at a rear surface of the second slide member  142 . 
     The second body  120  includes the second slide member  142  such that the second body moves with respect to the first body  110 . Second slide cover  122  encloses the second slide member  142  and the rear case  112  of the first body  110 . The third input interface  124  located on a lateral surface of the second slide cover  122  may be electrically connected to the printed circuit board  145  of the first body  110  by a flexible printed circuit board (FPCB). 
     The battery  131 , which supplies power to the first body  110 , is detachably mounted at a battery mount cavity  132  of the second slide cover  122 . The battery  131  fits into the receiving walls  133  surrounding four sides of the battery mount cavity  132 . 
     In the above described configuration according to an embodiment of the present invention, the first body  110  directly slides into the second body  120  via the slide module  140 . Therefore, the mobile terminal  100  can be made to be slimmer than the conventional slide type terminal having two completely separate bodies combined such that one body is slidably mounted directly on top of the other body and no portion of one body is inserted into the other body. The mobile terminal  100  according to the present invention may appear as a bar type terminal having a single body in the closed position and as a slide type terminal having two separate bodies connected to each other in the open position. 
     In the present invention, the battery  131  in the second body  120  moves with respect to the printed circuit board  145  of the first body  110  when the first body slides over the second body to be in the open or closed position. Therefore, the terminal  100  according to the present invention needs to have a structure of which the battery  131  and the printed circuit board  145  are electrically connected to each other regardless of the variable distance between the battery and the printed circuit board. Connection of the battery  131  and the printed circuit board  145  in the mobile terminal  100  according to the present invention will be described below. 
       FIGS. 5A and 5B  are bottom views of the slide module  140  according to an embodiment of the present invention. The rear surface of the slide module  140  is shown in the closed and open positions, respectively, in  FIGS. 5A and 5B . Referring to  FIGS. 5A and 5B , an elastic module  150  for providing an elastic force when the first and second slide members  141 ,  142  move with respect to each other is mounted between the first and second slide members. A battery mount portion  160  for mounting the battery  131  is formed at the rear surface of the second slide member  142 . A contact terminal  161  is disposed at the battery mount portion  160  to be in contact with a contact terminal  134  of the battery  131  which is placed in the battery mount cavity  132  of the second slide cover  122 . 
     A first connection point  162  is provided at the printed circuit board  145  mounted at the first slide member  141 , and a second connection point  163  is provided at the battery mount portion  160  of the second slide member  142 . The second connection point  163  is electrically connected to the contact terminal  161  by an electric wire. 
     The first connection point  162  and the second connection point  163  may be connected to each other by a coaxial cable  170 , thus minimizing a mounting space. Further, the coaxial cable  170  provides more stable power supply regardless of an external noise, compared to the flexible printed circuit board (FPCB). The first and second connection points  162 ,  163  may be disposed on the same side, for example, left or right side, of the printed circuit board  145  and the battery mount portion  160 . 
     For example, in  FIGS. 5A and 5B , the first and second connection points  162 ,  163  are disposed on the left side of the printed circuit board  145  and the battery mount portion  160 . The coaxial cable  170  connecting the first and second connection points  162 ,  163  is also disposed on the left side of the battery mount portion  160  in parallel with a sliding direction of the first and second slide members  141 ,  142 . 
     The coaxial cable  170  may be longer than the actual distance between the first and second connection points  162 ,  163  in the open position such that the coaxial cable is curved by 180 degrees at a curved portion  171 . As shown in  FIG. 5B , a protrusion  164  may be extending from the second slide member  142  between two parallel lines of the coaxial cable  170  to limit upward movement of the coaxial cable when opening the mobile terminal  100  by sliding the first body  110  with respect to the second body  120  such that the protrusion blocks the movement of the coaxial cable by contacting the curved portion  171  of the coaxial cable. 
     Further, a guide member  165  guiding the movement of the coaxial cable  170  may be formed at the second slide member  142 . The guide member  165  is provided with a through hole and the coaxial cable  170  moves through the through hole. When the mobile terminal  100  is transitioned from the closed position to the open position by relative movement of the first and second slide members  141 ,  142 , the coaxial cable  170  moves through the guide member  165 . The guide member  165  prevents the coaxial cable  170  from being twisted during the transition and the curved portion  171  of the coaxial cable  170  stops at the protrusion  164  when the terminal  100  transitions to the open position. 
       FIGS. 6A and 6B  are bottom views of the slide module  140  according to an embodiment of the present invention.  FIGS. 6A and 6B  show the rear surface of the slide module  140  in the closed and open configurations, respectively. 
     The elastic module  150  may be disposed between facing surfaces of the first and second slide members  141 ,  142  to open and close the first and second bodies  110 ,  120  semiautomatically by sliding the first and second slide members. The elastic module  150  may include a main body  153  and first and second rods  151 ,  152  coupled to the main body. One end of the first rod  151  is rotatably coupled to the first slide member  141  and the other end is linearly and movably coupled to the main body  153 . One end of the second rod  152  is rotatably coupled to the second slide member  142  and the other end is linearly and movably coupled to the main body  153 . 
     The first and second rods  151 ,  152  are supported by springs mounted in the main body  153 , and compress the springs by linearly moving in the main body when the first and second slide members  141 ,  142  move with respect to each other to transition between the closed and open positions. Depending on the distance between the first and second slide members  141 ,  142 , the springs are compressed or tensioned, providing the elastic force between the first and second slide members  141 ,  142  in a direction of the movement. 
     According to an embodiment of the present invention, the printed circuit board  145  and the battery mount portion  160  may be provided with the first and second connection points  162 ,  163 , respectively, which are coupled to each other by the coaxial cable  170 . The first connection points  62  is disposed on the left side of the elastic module  150  and the second connection point  163  is disposed on the right side of the elastic module. The coaxial cable  170  may be disposed along a circumference of the elastic module  150 . The coaxial cable  170  is long enough to encompass a portion of the elastic module  150  even in the open configuration. 
     The coaxial cable  170  is disposed along the circumference of the elastic module  150  to maximize a radius of curvature thereof, to prevent the coaxial cable  170  from being disconnected. The first connection point  162  may be disposed at the left side and the second connection point  163  may be disposed at the right side, or vice versa. 
     A configuration in which the coaxial cable  170  is connected to the first and second connection points  162 ,  163  will be described. The coaxial cable  170  is connected to the first connection point  162  formed on the printed circuit board  145 . However, a similar configuration may also be applied to the second connection point  163 .

The connecting unit  176  may include a first connecting portion  177  in which the outer conductor  174  is exposed, and a second connecting portion  178  extended from the first connecting portion  177  such that the inner conductor  172  is exposed. The first connecting portion  177  is formed not to have the outer coating  175  forming the exterior of the coaxial cable  170  and the second connecting portion  178  is formed not to have the outer coating  175 , the outer conductor  174  and the insulator  173 . 
     The first connection point  162  of the printed circuit board  145  includes first and second electrodes  181 ,  182  contacting the first and second connecting portions  177 ,  178 , respectively. The first electrode  181  is provided on the printed circuit board  145  and contacts the lateral surface of the first connecting portion  177 , and the second electrode  182  is formed at an inner wall of the through hole formed at the printed circuit board and contacts the second connecting portion  178  which is inserted into the through hole. The first and second connecting portions  177 ,  178  may be connected to the first and second electrodes  181 ,  182 , respectively, by soldering. The second connecting portion  178  is curved toward the through hole and configured to be inserted into the through hole. 
     The first connecting portion  177  and the first electrode  181  have the same polarity, and the second connecting portion  178  and the second electrode  182  have the same polarity. Moreover, if the first electrode  181  has a positive pole, the second electrode has a negative pole and vice versa.

     Referring to  FIG. 11 , the mobile terminal  100  according to an embodiment of the present invention includes a radio (wireless) communication module  191 , input units  115 ,  123 ,  124 , an image input unit  128 , a sound input unit  125 , a display portion  113 , a sound output unit  114 , a sensing unit  196 , an interface  116 , a broadcast receiving module  195 , a memory  194 , a power supply unit  131 , and a controller  190 . 
     The controller  190  generally controls the overall operation of the terminal  100 . For example, the controller  190  controls and processes operations such as voice calls, data communication, and video calls. 
     The radio communication module  191  transmits/receives radio signals to/from a mobile communication base station through an antenna. For example, the radio communication module  191  transmits/receives voice data, text data, image data and control data under control of the controller  190 . The radio communication module  191  includes a transmitting unit  193  for modulating and transmitting signals and a receiving unit  192  for demodulating the received signals. 
     The input unit or input interface  115 ,  123 ,  124  are configured as shown in  FIGS. 1 and 2  to receive data input by the user for controlling the operation of the terminal  100  with the controller  190 . The image input unit  128  processes an image frame such as still images and moving images that are obtained by an image sensor in an image call mode or a photographing mode. The processed image frame is converted into image data to be output and displayed on the display portion  113 . The image frame processed by the image input unit  128  may be stored in the memory  194  by the controlling unit  190  or transmitted through the radio communication module  191 . 
     The sound input unit  125  receives external sound signals through the microphone during a call mode, a recording mode, or a voice recognition mode and then processes the received sound signals into electric voice data. During the call mode, the processed voice data is converted and output to the mobile communication base station through the radio communication module  191 . In the recording mode, the processed voice data is output to be stored in the memory  194 . In the sound input unit  125 , various noise removing algorithm may be implemented to remove noise generated during the process of receiving external sound signals. 
     On the display portion  113 , information processed in the terminal  100  is output to be displayed. For example, when the terminal  100  is in the call mode, a UI (User Interface) or a GUI (Graphic User Interface) related to the call is displayed on the display portion  113  by the controlling unit  190 . When the terminal  100  is in the video call mode or the photographing mode, the photographed images, the UI or the GUI related to the corresponding mode is displayed on the display portion  113  by the controlling unit  190 . In one embodiment of the present invention, the display portion  113  may be used as an input device by being implemented as a touch screen. 
     The sound output unit  114  outputs the sound data received from the radio communication module  191  or stored in the memory  194  in a call signal receiving mode, the call mode, the recording mode, the voice recognition mode, or the broadcast receiving mode. The sound output unit  114  also outputs sound signals related to functions performed in the terminal  100 , such as call signal receiving sound and message receiving sounds. 
     The sensing unit  196  generates sensing signals for controlling the operation of the terminal  100  by sensing the current status of the terminal. The sensing unit  196  may sense an open/closed status and a position of the terminal  100 , and also determines whether a user is contacting the terminal. For example, the sensing unit  196  senses whether the terminal  100  is in the open or closed status, and then outputs the sensed result to the controller  190  to control the operation of the terminal. The sensing unit  196  also senses whether the power is supplied in the power supply unit  131  and whether the interface  116  is coupled to external devices. 
     The interface  116  serves to electrically connect all external devices such as a wire/wireless headset, an external charger, a wire/wireless data port, a card socket, such as memory card and SIM/UIM card, to the terminal  100 . Such interface  116  allows the data or power transmitted or supplied from the external device to be transferred to each component of the terminal  100 , or the data in the terminal to be transmitted to the external device. 
     In the memory  194 , a program for processing and controlling the controller  190  may be stored, or input/output data, such as phonebook, messages, still images, and moving images, may also be stored. Further, a program controlling the operation of the terminal  100  may be stored in the memory  194 . Such memory  194  may be implemented as a hard disk, a flash memory, a RAM, a ROM, and a card-type memory, such as SD and XD memory. 
     The broadcast receiving module  195  receives broadcast signals transmitted through a satellite wave or a ground wave and outputs the received broadcast signals to the controller  190  by converting the signals into broadcast data that can be output to the sound output unit  114  and the display portion  113 . The broadcast receiving module  195  may receive additional data related to the broadcasting, such as EPG (Electric Program Guide) and channel list. The additional data and the broadcast data converted by the broadcast receiving module  195  may be stored in the memory  194 . The power supply unit  131  supplies power to operate each component. 
     In the present invention, the first components mounted in the first body are fixed to the first slide member and the second components mounted in the second body are fixed to the second slide member, achieving a terminal having a slimmer thickness. Further, a new type of opening/closing structure according to the present invention provides implementation of a bar type terminal in the closed configuration and a slide type terminal in the open configuration. Furthermore, in the present invention, the printed circuit board and the battery are connected to each other through the coaxial cable, thereby minimizing the mounting space and stably supplying power regardless of the external noise. 
     The foregoing embodiments and advantages are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses and processes. The description of the present invention is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art.
