     DETAILED DESCRIPTION OF THE INVENTION 
     Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. 
       FIG. 1  is a block diagram schematically illustrating a configuration of a mobile terminal according to an exemplary embodiment of the present invention.  FIGS. 2A to 2E  illustrate the mobile terminal of  FIG. 1  through a plan view, a front view, a side view, a bottom view, and a rear view,  FIG. 3  is a perspective view illustrating a second body included in the mobile terminal of  FIG. 1 .  FIG. 4  is a perspective view illustrating a state in which a first body has been extended from the second body in the mobile terminal of  FIG. 1 . 
     As shown in  FIG. 1 , the mobile terminal includes a broadcast receiver  1 , a radio transceiver  2 , a memory  3 , a display unit  10 , a camera  5 , and a controller  4 . Referring to  FIG. 1 , the broadcast receiver  1 , radio transceiver  2 , memory  3 , display unit  10 , camera  5 , and controller  4  are appropriately arranged at a first body  100  or at a second body  200  in accordance with the function thereof. 
     For example, the broadcasting receiver  1  is arranged at the second body  200  to receive mobile broadcasting such as Korean terrestrial digital multimedia broadcasting (DMB) and satellite DMB, U.S. media forward link only (MediaFlo), and European digital video broadcasting-handheld (DVB-H). 
     The radio transceiver  2  is arranged, for example, at the second body  200 , to process transmission and reception of radio signals associated with mobile communications. In particular, the radio transceiver  2  enables the user to perform various communication services, such as voice communication, short message service (SMS), multimedia message service (MMS), and E-mail, with a third party. 
     The memory  3  is arranged, for example, at the second body  200 , to store various software, firmware, and various data required for operations of the mobile terminal. In particular, the memory  3  may store various multimedia contents to be played back in the mobile terminal. 
     The display unit  10  is arranged, for example, at the first body  100 , to display information or images required for use of the mobile terminal. If necessary, the display unit  10  may be configured to permit a touch screen function, enabling the user to conveniently input more diverse commands using his/her finger(s) and/or a pen-like device. 
     The camera  5  is arranged, for example, on the back surface of the second body  200 , to enable the user to photograph a still image or moving image of an object. 
     The controller  4  functions to control the broadcasting receiver  1 , radio transceiver  2 , memory  3 , display unit  10 , and camera  5 . The controller  4  includes a multimedia player  4   a  for playing back multimedia contents. Accordingly, the controller  4  can play back multimedia contents stored in the memory  3 . Furthermore, the multimedia player  4   a  may be provided as a constituent element independent of the controller  4 . 
     In addition, the controller  4  performs a control operation to change the configuration of a screen of the display unit  10  (e.g., viewable screen size) in accordance with a degree of extension of the first body  100  from a receiving part. Here, the degree of extension refers to how much screen is viewable by the user. 
     For example, the controller  4  changes the information displayed on the screen of the display unit  10  or the font size of texts displayed on the screen of the display unit  10  in accordance with the outwardly-exposed area of the screen of the display unit  10 . This will be described in more detail later. 
     The first body  100  is provided with a display  110  for displaying information desired by the user, and a panel  120  surrounding the display  110 . 
     Referring to  FIG. 3 , the second body  200  includes a receiving part  210  for receiving the display  110 . The display  110  can be completely received in the receiving part  210  or can be extended from the receiving part  210  in accordance with a user&#39;s selection. 
     The second body  200  has a substantially-rectangular shape. A cutout  220  is formed at one surface of the second body  200 , for example, an upper surface of the second body  200 , in order to allow the display  110  to display information even when the display  110  is completely received in the receiving part  210 . That is, a part of the display  110  is available for viewing even when the display  110  is completely received by the receiving part  210 . 
     The cutout  220  is formed at one of the two longer sides of the second body  200  such that the cutout  220  extends along one surface of the second body  200 , for example, the upper surface of the second body  200 . Here, the cutout  220  refers to a recessed area provided in the second body  200  for receiving the first body  100 . 
     The “rectangular shape” described in the specification is not limited to mean that the neighboring sides forms a corner having an angle of 90°, as the meaning in the dictionary. The “rectangular shape” described in the specification includes even a shape that is recognizable to be a rectangular shape by the general public at first sight, even though it has round corners and opposite sides thereof have a slight length difference. 
     It is also acceptable to have the second body  200  with a circular shape or various polygonal shapes. 
     Referring to  FIG. 4 , the first body  100  can be inserted into or extended from the receiving part  210  in a sliding manner. For example, the peripheral edge of the first body  100 , e.g., the panel  120 , can be outwardly extended from the receiving part  210  while sliding along a guide  230  provided at the second body  200  toward the outside of the cutout  220 . 
     Procedures associated with inserting and extending the first body  100  into and from the second body  200  in the mobile terminal will be descried with reference to  FIGS. 5A and 5B . 
     The mobile terminal according to the illustrated embodiment includes couplers  300  for coupling the first and second bodies  100  and  200 . In detail, when the user applies slightpressure and releases the pressure to the first body  100  in a received state the coupled state of the first and second bodies  100  and  200  maintained by the couplers  300  is temporarily released. At the same time, the first body  100  is automatically extended from the second body  200  in accordance with the resilience or elasticity of elastic members included in the couplers  300 . 
     If the user presses the upper end of the first body  100  extended from the second body  200  until the first body  100  is completely inserted into the second body  200 , the first body  100  is again coupled to the second body  200  by the couplers  300 . 
     For example, each coupler  300  includes a moving member  330 , which slides in conjunction with the first body  100 , a coupling member  320  for receiving at least a portion of the moving member  330 , a rotating member  350 , which rotates while moving linearly in accordance with a movement of the moving member  330 , and an elastic member  310  having a resilience/elasticity against the movement of the moving member  330 . 
     The coupling member  320  provides a passage allowing at least portions of the moving member  330  and rotating member  350  to be inserted into the passage and to move along the passage. The moving member  330  is provided with first inclined protrusions  331  having inclined surfaces, whereas the rotating member  350  is provided with second inclined protrusions  351  having inclined surfaces corresponding to the inclined surfaces of the first inclined protrusions  331 . The coupling member  320  is provided, at an inner surface thereof, with grooves (not shown) providing movement paths for the first and second inclined protrusions  331  and  351 . 
     In accordance with the above-described structure of each coupler  300 , if the user pushes the first body  100  toward the receiving part  210 , the moving member  330  fixedly connected to the first body  100  is moved along with the first body  100 . 
     At this time, the first inclined protrusions  331  of the moving member  330  pushes the second inclined protrusions  351  of the rotating member  350 , thereby causing the rotating member  350  to rotate. As a result, the second inclined protrusions  351  of the rotating member  350  is selectively engaged with or disengaged from the grooves (not shown) of the coupling member  320 . Thus, the first body  100  is selectively coupled to or released from the second body  200 . Here, the elastic member has a resilience against the movement of the moving member  330 . 
     The mobile terminal further includes an antenna for receiving a signal transmitted from the external source (e.g., mobile broadcasting). In detail, the antenna includes a first antenna  151  arranged at the first body  100 , and a second antenna  153  arranged at the second body  200 . 
     The first and second antennas  151  and  153  function as a single telescopic type antenna in a state in which the first body  100  is outwardly extended from the receiving part  210  of the second body  200 , as shown in  FIG. 5A . 
     On the other hand, when the first body  100  is received in the receiving part  210  of the second body  200 , as shown in  FIG. 5B , at least a portion of the first antenna  151  is received by the second antenna  153 . In other words, at least a portion of the first antenna  151  is inserted to an inner space of the second antenna  153 . 
     Thus, there is an advantage in that a desired antenna function can be efficiently achieved with a limited space. Here, the first and second antennas  151  and  153  are arranged inside of the first and second bodies  100  and  200  without being outwardly protruded or extended from the mobile terminal. Further, there is also an advantage in that the first and second antennas  151  and  153  do not interfere with external objects, while simplify the appearance of the mobile terminal. 
     The mobile terminal may also include a position sensor  160  for sensing the position of the first body  100  or second body  200 . 
     The position sensor  160  includes a first position sensor  161  arranged at the first body  100 , and a second position sensor  163  arranged at the second body  200  such that the second position sensor  163  corresponds to the first position sensor  161 . 
     A method for identifying the positions of the first and second bodies  100  and  200  using the first and second position sensors  161  and  163  will be described in brief hereinafter. 
     If the first body  100  is received in the receiving part  210  of the second body  200 , at least a portion of the first position sensor  161  is received in the second position sensor  163 . As the first body  100  is extended from the receiving part  210 , the insertion length of the first position sensor  161  inserted into the second position sensor  163  decreases gradually. 
     When the first body  100  is subsequently completely extended from the receiving part  210 , the first position sensor  161  is also completely extended from the second position sensor  163 . Here, the insertion length of the first position sensor  161  can be identified based on a resistance and/or a capacitance between the first and second position sensors  161  and  163 . 
     The present invention is not limited to the above-described embodiment. Any other position sensor may be used as long as it can sense a movement of the first body  100  with respect to the second body  200 . 
     For example, a light emitter for emitting light and a light receiver for receiving light may be provided at the second body  200 , and a reflector for reflecting the light emitted from the light emitter may be provided at the first body  100 , in order to detect the position of the first body  100  with respect to the second body  200 . 
     In this case, the controller  4  may measure the amount of time taken for the light emitted from the light emitter to be received by the light receiver via the reflector, and thus, may measure the distance between the first and second bodies  100  and  200 . 
     Data generated in accordance with the measurement by the position sensor  160  is used to adjust the screen size of the display  110  for displaying an image. This will be described in detail later. 
     Meanwhile, the first body  100  may be tilted or angled with respect to the second body  100  after being completely outwardly extended from the second body  200 , as shown in  FIGS. 6A to 6D . To this end, a hinge  140  is arranged between the first and second bodies  100  and  200 . The hinge  140  may include an angle adjuster for adjusting the rotating angle of the first body  100  with respect to the second body  200 . Accordingly, the user can conveniently view the screen of the display  110 . 
     Hereinafter, the state of image information displayed on the display when an MP3 music file is played in the mobile terminal according to the present invention will be described with reference to  FIGS. 7A and 7B . 
     Information is displayed on the screen even when the first body  100  is completely received in the receiving part  210  of the second body  200 , as shown in  FIG. 7A . In detail, an image associated with the MP3 music file (e.g., song title, song text, and artist) is displayed in various forms on a portion of the screen of the display  110 , which corresponds to the size of the cutout (“ 220 ” in  FIG. 3 ). 
     For example, a two-line text with a font size of 6 pt may be displayed in a sliding manner on the screen corresponding to the size of the cutout as the associated data (e.g., MP3 file) is accessed. 
     Thus, it is possible to achieve a reduction in power consumption because image information is displayed only on a screen portion of the display  110  of the first body  100 , which is outwardly exposed in a received state of the display  110  in the receiving part  210 , namely, a screen portion of the display  110  corresponding to the cutout. 
     On the other hand, when an MP3 music file is played when the first body  100  is completely outwardly extended from the receiving part  210 , as shown in  FIG. 7B , an image associated with the MP3 music file is displayed in an appropriate form (e.g., a text with a font size of 8 pt and a wide graphic user interface (GUI) equalizer) on the screen of the display  110  in the whole screen size. 
     Thus, the controller  4  of the mobile terminal performs a control operation to change the configuration of the screen of the display unit  10  in accordance with an the degree of extension of the first body  100  from the second body  200 . The degree of extension or protrusion of the first body  100  from the second body  200  may be measured using the position sensors as described with reference to  FIG. 5 . 
     Hereinafter, image information displayed on the display  110  when an SMS message is received by the mobile terminal according to the present invention will be described with reference to  FIGS. 8A and 8B . 
     Information is displayed on the screen even when the first body  100  is completely received in the receiving part  210  of the second body  200 , as shown in  FIG. 8A . In detail, an image associated with an SMS message (e.g., originator, sent time, and message content) is displayed in various forms on a portion of the screen of the display  110 , which corresponds to the size of the cutout  220 . 
     On the other hand, when the first body  100  is completely outwardly extended from the receiving part  210 , as shown in  FIG. 8B , information associated with the SMS message is displayed on the entire screen of the display  110 . 
     No further detailed description will be given of the identification of the SMS message because image information associated with the SMS message is displayed on the display in a similar manner to that of playback of an MP3 music file. 
     Now, the procedure, in which the configuration of the screen of the display is changed in accordance with the extension degree of the display, will be described with reference to  FIGS. 9A to 9C . 
     When the first body  100  is completely received in the receiving part  210 , as shown in  FIG. 9A , image information is displayed on a portion of the screen which is outwardly exposed through the cutout  220 . 
     The screen size of the display  110  can be changed or modified in accordance with the degree of extension the display  110  of the first body  100  from the receiving part  210  of the second body  200 , as shown in  FIG. 9B  or  9 C. That is, the controller  4  included in the mobile terminal controls the screen size, based on the degree of extension of the display  110  from the receiving part  210 . 
     The degree of extension of the first body  100  from the receiving part  210  can be identified through the position sensor as described above with reference to  FIGS. 5A and 5B . As discussed, the degree of extension refers to the amount of screen that is slided outwardly from the completely received position. If the first body  100  is completely received, the viewable screen size of the display  110  is smaller than if the first body  100  is completely extended. 
     Thus, there is an advantage in that the user can view a moving image through a reduced-size screen at a position near the screen in a congested place, for example, in a subway train, by slightly extending the first body from the second body, and can view the moving image through a whole-size screen in a space allowing the user to be independent, by completely extending the first body from the second body. 
     It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents. 
     The above-described mobile terminal according to the present invention has the following effects. 
     First, in accordance with the present invention, there is an advantage in that the user can easily identify desired information because a portion of the display is in an outwardly-exposed state. 
     For example, the display is configured to be tiltable in accordance with the position of the user. Accordingly, it is possible to more conveniently view multimedia contents played back through the mobile terminal. 
     Second, in accordance with the present invention, the screen size of the display can be automatically adjusted based on the extension degree of the first body with respect to the second body. 
     Accordingly, there is an advantage in that it is possible to conveniently view multimedia contents even in a congested place, for example, in a subway train, after appropriately adjusting the screen size. Also, there is an advantage in that it is possible to reduce the power consumption caused by the display, if necessary. 
     Third, in accordance with the present invention, the mobile broadcasting receiving antenna can be formed integrally with the housing of the terminal. Accordingly, there is an advantage in that it is possible to enhance the reliability of the mobile terminal because it is possible to receive mobile broadcasting without using an outwardly-protruded antenna. 
     Fourth, in accordance with the present invention, there is an advantage of a reduction in power consumption in that the display of the first body displays an image only on a screen portion exposed through the cutout when the display of the first body is completely received in the receiving part of the second body.
