CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    The present application claims priority from Japanese Patent Application No. JP 2009-103024 filed in the Japanese Patent Office on Apr. 21, 2009, the entire content of which is incorporated herein by reference. 
       BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to an information processing device, and particularly relates to an information processing device capable of connecting a body and a display included in the information processing device by radio. 
         [0004]    2. Description of the Related Art 
         [0005]    In related art, as an information processing device in which a body and a display are integrally formed, there exists, for example, a so-called notebook personal computer (for example, refer to JP-A-2004-253939 (Patent Document 1)). 
         [0006]    In the notebook personal computer, the body and the display is connected by a hinge and the like, and the display is rotated about the hinge as a rotational axis to thereby open and close the display. 
       SUMMARY OF THE INVENTION 
       [0007]    In the notebook personal computer in related art, the body and the display are connected by cables for supplying a video signal and the like, which is housed in the hinge. 
         [0008]    Accordingly, the cables closely housed and routed in the hinge are likely to be broken due to abrasion, for example, by repeatedly opening and closing the display. In such case, the video signal and the like are not supplied from the body to the display, as a result, it is difficult to display a display screen on the display. 
         [0009]    Also in the notebook personal computer in related art, it is necessary to arrange cables between the body and the display, therefore, space (vacancy) for arranging cables have to be provided between the body and the display. 
         [0010]    Accordingly, the angle and orientation of the display are limited, and degree of freedom in designing the notebook personal computer is likely to be reduced. 
         [0011]    In view of the above, it is desirable to connect the body and display by ratio. 
         [0012]    According to an embodiment of the invention, there is provided an information processing device including a display means having a receiving surface for receiving data transmitted by wireless communication and a supporting means having a transmitting surface for transmitting the data by the wireless communication and supporting the display means, in which the supporting means supports the display means in a position in which the wireless communication can be performed. 
         [0013]    The supporting means can support the display means in a position in which the data transmitted from the transmitting surface can be received only by the receiving surface. 
         [0014]    The supporting means can support the display means so as to be detachable. 
         [0015]    The display means has a rectangular parallelepiped shape and the supporting means supports the display means in landscape orientation or in portrait orientation. 
         [0016]    The display means can include a first receiving surface receiving the data transmitted from the transmitting surface by the wireless communication when the display means is supported in landscape orientation, and a second receiving surface receiving the data transmitted from the transmitting surface by the wireless communication when the display means is supported in portrait orientation. 
         [0017]    The first receiving surface and the second receiving surface can be the same receiving surface. 
         [0018]    The supporting means can further support the display means so as to be rotatable about the supporting means as a rotational axis. 
         [0019]    The supporting means can support the display means in a position in which the wireless communication is not capable of being performed when the wireless communication is not performed. 
         [0020]    The supporting means can support the display means so as to slide in a given direction. 
         [0021]    The display means can include a first receiving surface receiving the data transmitted from the transmitting surface by the wireless communication when the display means is supported in the state of being slid in the given direction, and a second receiving surface different from the first receiving surface, receiving the data transmitted from the transmitting surface by the wireless communication when the display device is supported in the state of not being slid in the given direction. 
         [0022]    The supporting means can include a first transmitting surface transmitting the data by the wireless communication when the display means is supported in the state of being slid in the given direction, and a second transmitting surface different from the first transmitting surface, transmitting the data by the wireless communication when the display device is supported in the state of not being slid in the given direction. 
         [0023]    The supporting means can support the display means so that a display screen of the display means is directed to a given direction or a direction opposite to the given direction. 
         [0024]    The display means can display an image corresponding to the data received by the receiving surface, and the transmitting surface included in the supporting means can transmit the data at a transfer speed corresponding to a display speed of the image displayed by the display means. 
         [0025]    The supporting means can support the display means in a position in which the transmitting surface faces the receiving surface. 
         [0026]    The transmitting surface included in the supporting means and the receiving surface included in the display means can perform the wireless communication by TransferJet (Registered Trademark of Sony Corporation). 
         [0027]    According to an embodiment of the invention, a display means including a receiving surface receiving data transmitted by wireless communication is supported by a supporting means including a transmitting surface transmitting the data by the wireless communication and supporting the display means in a position in which the wireless communication can be performed. 
         [0028]    According to an embodiment of the invention, the body and the display can be connected by radio.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0043]    Hereinafter, best modes for carrying out the invention (refer to as embodiments in the following description) will be explained. The explanation will be made in the following order.

         [0050]    7. Seventh Embodiment (Example of a cellular phone device which can slide) 
         [0051]    8. Eighth Embodiment (Another example of a cellular phone device which can slide) 
         [0052]    9. Modification Embodiment 
       First Embodiment  
       [0053]      FIG. 1  shows an appearance example of a single unit computer  1  seen from the front according to a first embodiment. 
         [0054]    The single unit personal computer (referred to as a single unit PC in the following description) includes a body  21  and a display portion  22  attachable to and detachable from the body  21 . 
         [0055]    The body  21  supplies a video signal to the display portion  22  by a close-range high speed wireless communication while mounting (supporting) the display portion  22  to display an image corresponding to the video signal. 
         [0056]    Here, the close-range high speed wireless communication is wireless communication performed between the body  21  and the display portion  22 , which is the wireless communication in which a wireless signal is exchanged between the body  21  and the display portion  22  which are in close proximity to each other to a degree that the signal is not received by communication devices other than the body  21  and the display portion  22 . 
         [0057]    In the close-range high speed wireless communication, the video signal is transferred at high speed from the body  21  to the display portion  22  at a transfer speed (for example, a transfer speed in which the image displayed on the display portion  22  is not frozen) in accordance with a display speed of the image corresponding to the video signal, which is displayed by the display portion  22 . 
         [0058]    As the close-range high speed wireless communication, there exists TransferJet (Registered Trademark of Sony Corporation) performing wireless communication at a transfer rate approximately of 560 [Mbps] at a close range of approximately 3 cm by electromagnetic waves, however, other close-range high speed wireless communications and the like different from TransferJet (Trademark) can be used in the first to eighth embodiments, in addition to TransferJet (Trademark). 
         [0059]    The body  21  is provided with, in addition to an operation portion  21   a  such as a keyboard and a touch pad, supporting columns  21   b,    21   c  used for supporting the display portion  22  and a coupler  21   d  which is an antenna including a transmitting/receiving surface for transmitting or receiving data such as a video signal by electromagnetic waves in the close-range high speed wireless communication. 
         [0060]    The body  21  includes a CPU (central processing unit), a ROM (read only memory), a RAM (random access memory) and an HDD (hard disk drive) and the like. 
         [0061]    The display portion  22  is provided with, in addition to an LCD (liquid crystal display)  22   a,  supporting holes  22   b ,  22   c  pierced and fixed by supporting columns  21   b,    21   c  respectively and a coupler  22   d  which is an antenna having a transmitting/receiving surface for transmitting or receiving data by electromagnetic waves in the close-range high speed wireless communication. 
         [0062]    When the body  21  supports the display portion  22  by the supporting holes  22   b,    22   c  in the display portion  22  being pierced and fixed by the supporting columns  21   b,    21   c  in the body  21 , the transmitting/receiving surface of the coupler  21   d  and the transmitting/receiving surface of the coupler  22   d  are arranged face to face (arranged so as to face each other) at close range. 
         [0063]    In this case, the close-range high speed wireless communication using the coupler  21   d  and the coupler  22   d  is started between the body  21  and the display portion  22  in response to the arrangement of the transmitting/receiving surfaces facing each other. 
         [0064]    Additionally, power is supplied from the body  21  to the display portion  22  by an existing feeding method of supplying power by radio while the display portion  22  is mounted on the body  21 . 
         [0065]    It is also preferable that a battery is built in the display portion  22  and feeding is started by the battery in response to the supply of the video signal from the body  21  using the close-range high speed wireless communication. 
         [0066]    As the feeding method performed by the body  21  with respect to the display portion  22  while the body  21  supports the display portion  22 , a wired feeding method can be applied in addition to the wireless feeding method. 
         [0067]    The feeding method performed by the body  21  with respect to the display portion  22  while the body  21  supports the display portion  22  is the same in the later described second to eighth embodiments, therefore, explanation thereof will be omitted. 
         [0068]    In the first embodiment, the video signal from the body  21  to the display portion  22  is supplied by the close-range high speed wireless communication by radio, instead of the wired communication. 
         [0069]    Since it is not necessary to connect the body  21  to the display portion  22  by cables in the first embodiment, a situation in which the video signal is not supplied from the body  21  to the display portion  22  by breaking of cables can be prevented. 
         [0070]    Additionally, for example, it is not necessary to secure the space for arranging cables between the body  21  and the display portion  22 , therefore, it is possible to prevent the degree of freedom in designing the single unit PC  1  from being limited by securing the space for arranging cables. 
         [0071]    Furthermore, since the body  21  and the display portion  22  are not connected by cables in the first embodiment, it is possible to exchange the display portion  22  with another display portion easily. 
         [0072]    Therefore, for example, even when the display portion  22  is out of order, the display portion  22  can be easily exchanged with another display portion which normally operates. The display portion  22  can be also exchanged with a display portion having a different size in accordance with application easily. 
       Second Embodiment  
       [0073]    Next, a single unit PC  41  according to a second embodiment will be explained with reference to  FIG. 2  and  FIG. 3 . 
         [0074]      FIG. 2  and  FIG. 3  show appearance examples of the single unit PC  41  seen from the front according to the second embodiment. 
         [0075]    The single unit PC  41  includes a body  61  and a display portion  62  attachable to and detachable from the body  61  in landscape orientation or in portrait orientation. 
         [0076]    The body  61  supplies a video signal to the display portion  62  by a close-range high speed wireless communication while supporting the display portion  62  to display an image corresponding to the video signal. 
         [0077]    The body  61  is provided with, in addition to an operation portion  21   a  such as a keyboard and a touch pad, a convex portion  61   b  used for supporting the display portion  62  and couplers  61   c,    61   d  formed in the same manner as the coupler  21   d  of  FIG. 1 . 
         [0078]    The display portion  62  has an approximately rectangular parallelepiped shape. 
         [0079]    The display portion  62  is provided with, in addition to a LCD  62   a,  concave portions  62   b,    62   c  to be fitted and fixed to the convex portion  61   b  and couplers  62   d,    62   e  formed in the same manner as the coupler  22   d  of  FIG. 1  at a lower right position in the drawing. 
         [0080]    When the convex portion  61   b  of the body  61  is fitted to the concave portion  62   c  of the display portion  62  (in the case where the body  61  supports the display portion  62  in landscape orientation) as shown in  FIG. 2 , the transmitting/receiving surface of the coupler  61   d  of the body  61  and the transmitting/receiving surface of the coupler  62   e  of the display portion  62  are arranged so as to face each other at close range. 
         [0081]    On the other hand, when the convex portion  61   b  of the body  61  is fitted to the concave portion  62   b  (when the body  61  supports the display portion  62  in portrait orientation) as shown in  FIG. 3 , the transmitting/receiving surface of the coupler  61   c  of the body  61  and the transmitting/receiving surface of the coupler  62   d  of the display portion  62  are arranged so as to face each other at close range. 
         [0082]    In both cases shown in  FIG. 2  and  FIG. 3 , the close-range high speed wireless communication is started between the body  61  and the display portion  62  in response to the arrangement of the transmitting/receiving surfaces facing each other. 
         [0083]    In the second embodiment, the couplers  61   c,    61   d  are arranged at the body  61  and the couplers  62   d,    62   e  are arranged at the display portion  62  respectively so that the transmitting/receiving surfaces of the coupler  61   d  and the coupler  62   e  face each other when the body  61  supports the display portion  62  in landscape orientation (in the state shown in  FIG. 2 ) as well as so that the transmitting/receiving surfaces of the coupler  61   c  and the coupler  62   d  face each other when the body  61  supports the display portion  62  in portrait orientation (in the state shown in  FIG. 3 ). 
         [0084]    When the transmitting/receiving surfaces of the couplers are arranged face to face, the close-range high speed wireless communication is performed. 
         [0085]    Therefore, in the second embodiment, it is not necessary to connect the body  61  and the display portion  62  by wire. 
         [0086]    Accordingly, it is possible to change the state of the display portion  62  to be landscape orientation or portrait orientation according to application in the second embodiment. 
         [0087]    In the second embodiment, the coupler  62   d  is provided at the display portion  62  so that the close-range high speed wireless communication can be performed when the display portion  62  is mounted in portrait orientation. 
         [0088]    However, when a new coupler is horizontally provided at a lower right position in the display portion  62  instead of the coupler  62   d  in the display portion  62  in  FIG. 3  and the display portion  62  is mounted so as to approach the right edge from the center (with an offset), the close range high speed wireless communication can be performed by using the new coupler and the coupler  61   d  of the body  61 . 
         [0089]    Since the coupler  61   c  of the body  61  is not necessary in this case, a simpler configuration can be realized as compared with the case in which the couplers  61   c ,  61   d  are provided at the body  61 . 
       Third Embodiment  
       [0090]    Next, a single unit PC  81  according to a third embodiment which includes one coupler  101  instead of two couplers  62   d  and  62   e  will be explained with reference to  FIG. 4  and  FIG. 5 . 
         [0091]      FIG. 4  and  FIG. 5  show appearance examples of the single unit PC  81  seen from the front according to the third embodiment. 
         [0092]    In the single unit PC  81 , the same signs are given to components formed in the same manner as the single unit PC  41  according to the second embodiment, therefore, explanation thereof will be omitted below. 
         [0093]    That is, the single unit PC  81  is formed in the same manner as the single unit PC  41  except that the coupler  101  is provided instead of the coupler  62   d  and coupler  62   e  in the display portion  62 . 
         [0094]    In the display portion  62 , the coupler  101  is provided obliquely at a corner portion of the lower right direction of the display portion  62  in  FIG. 4  so that an angle with respect to the horizontal direction of  FIG. 4  is 45 degrees. 
         [0095]    When the convex portion  61   b  of the body  61  is fitted to the concave portion  62   c  of the display portion  62  (when the body  61  supports the display portion  62  in landscape orientation) as shown in  FIG. 4 , the transmitting/receiving surface of the coupler  61   d  of the body  61  and the transmitting/receiving surface of the coupler  101  of the display portion  62  are arranged at close range so that the angle formed by respective transmitting/receiving surfaces is 45 degrees. 
         [0096]    When the convex portion  61   b  of the body  61  is fitted to the concave portion  62   b  of the display portion  62  (when the body  61  supports the display portion  62  in portrait orientation) as shown in  FIG. 5 , the transmitting/receiving surface of the coupler  61   c  of the body  61  and the transmitting/receiving surface of the coupler  101  of the display portion  62  are arranged at close range so that the angle formed by respective transmitting/receiving surfaces is 45 degrees. 
         [0097]    In both cases shown in  FIG. 4  and  FIG. 5 , the close-range high speed wireless communication is started between the body  61  and the display portion  62  in response to the arrangement of the transmitting/receiving surfaces at close range in the state in which the angle formed by the respective transmitting/receiving surfaces is 45 degrees. 
         [0098]    In the third embodiment, when the body  61  supports the display portion  62  in landscape orientation (the state shown in  FIG. 4 ), the transmitting/receiving surfaces of the coupler  61   d  of the body  61  and the coupler  101  of the display portion  62  are arranged so that the angle formed by the respective transmitting/receiving surfaces is 45 degrees. 
         [0099]    In the third embodiment, when the body  61  supports the display portion  62  in portrait orientation (the state shown in  FIG. 5 ), the transmitting/receiving surfaces of the coupler  61   c  of the body  61  and the coupler  101  of the display portion  62  are arranged so that the angle formed by the transmitting/receiving surfaces is 45 degrees. 
         [0100]    Therefore, in the third embodiment, it is possible to reduce the number of couplers to be provided at the display portion  62  as compared with the case according to the second embodiment. 
         [0101]    Also in the third embodiment, when the respective transmitting/receiving surfaces of the couplers are arranged so that the angle formed by the transmitting/receiving surfaces is 45 degrees, the close-range high speed wireless communication by radio is performed to control the display portion  62 . 
         [0102]    Accordingly, it is not necessary to connect the body  61  to the display portion  62  by wire in the third embodiment. 
       Fourth Embodiment  
       [0103]    Next,  FIG. 6  shows an appearance example of a computer  121  according to a fourth embodiment. 
         [0104]    The computer  121  includes a body  141  and a display portion  142  which is rotatable with respect to the body  141 . 
         [0105]    The body  141  supplies a video signal to the display portion  142  by the close-range high speed wireless communication while supporting the display portion  142  to display an image corresponding to the video signal. 
         [0106]    The body  141  is provided with, in addition to an operation portion  141   a  such as a keyboard and a touch pad, a convex portion  141   b  used for supporting the display portion  142  and a coupler  141   c  formed in the same manner as the coupler  21   d  of  FIG. 1  at the center of the convex portion  141   b.    
         [0107]    The display portion  142  is provided with, in addition to a LCD  142   a,  a concave portion  142   b  which is fitted and fixed to the convex portion  141   b,  rotatable about the convex portion  141   b  as a rotational axis and a coupler  142   c  formed in the same manner as the coupler  22   b  of  FIG. 1  inside the concave portion  142   b.    
         [0108]    When the body  141  supports the display portion  142  by the convex portion  141   b  of the body  141  being fitted to the concave portion  142   b  of the display portion  142  as shown in  FIG. 6 , the transmitting/receiving surface of the coupler  141   c  of the body  141  and the transmitting/receiving surface of the coupler  142   c  of the display portion  142  are arranged face to face at close range. 
         [0109]    In this case, the close-range high speed wireless communication using the coupler  141   c  and the coupler  142   c  is started between the body  141  and the display portion  142  in response to the arrangement of the respective transmitting/receiving surfaces facing each other. 
         [0110]    In the fourth embodiment, when the body portion  141  supports the display portion  142 , the transmitting/receiving surfaces of the coupler  141   c  of the body  141  and the coupler  142   c  of the display portion  142  are arranged so as to face each other. Then, the close-range high speed wireless communication by radio is performed in response to the arrangement of the transmitting/receiving surfaces facing each other. 
         [0111]    Accordingly, it is not necessary to connect the body  141  to the display portion  142  by wire in the fourth embodiment. 
         [0112]    Also in the fourth embodiment, when the convex portion  141   b  of the body  141  is fitted to the concave portion  142   b  of the display portion  142 , the display portion  142  (concave portion  142   b ) can be rotated about the convex portion  141   b  of the body  141  as the rotational axis. 
         [0113]    Accordingly, for example, it is possible to allow a person sitting opposite to an operator to view a surface on which the LCD  142   a  of the display portion  142  is arranged easily just by rotating the display portion  142 . 
         [0114]    Therefore, it is not necessary to move the entire computer  121  in order to allow the person sitting opposite to the operator to view the LCD  142   a  of the display portion  142 . 
         [0115]    It is also possible to rotate the display portion  142  about the convex portion  141   b  as the rotational axis clockwise or counterclockwise any number of times (more than 360 degrees). 
         [0116]    Therefore, after the surface on which the LCD  142   a  of the display portion  142  is arranged is allowed to be viewed by the person sitting opposite to the operator by rotating the display portion  142 , the surface on which the LCD  142   a  is arranged can be directed toward the user by rotating the display portion  142  both clockwise and counterclockwise. 
       Fifth Embodiment  
       [0117]    Next,  FIG. 7  shows an appearance example of a computer  161  seen from the front according to a fifth embodiment. 
         [0118]    In the computer  161 , the same signs are given to components formed in the same manner as the computer  121  according to the fourth embodiment, therefore, explanation thereof will be omitted below. 
         [0119]    That is, the computer  161  is formed in the same manner as the computer  121  except that a display portion  181  is provided instead of the display portion  142 . 
         [0120]    The display portion  181  includes, in addition to an LCD  181   a,  a concave portion  181   b  to be fitted and fixed to the convex portion  141   b  so that a surface on which the LCD  181   a  is provided is directed toward the body  141  side and a coupler  181   c  formed in the same manner as the coupler  22   d  of  FIG. 1  inside the concave portion  181   b.    
         [0121]    The display portion  181  also includes a concave portion  181   d  to be fitted and fixed to the convex portion  141   b  so that the surface on which the LCD  181   a  is provided is directed to the opposite side of the body  141  side and a coupler  181   e  formed in the same manner as the coupler  22   d  of  FIG. 1  inside the concave portion  181   d.    
         [0122]    The same display screen (not display screens having different orientations) is displayed on the LCD  181   a  both in the case in which the convex portion  141   b  is fitted to the concave portion  181   d  and in the case in which the convex portion  141   b  is fitted to the concave portion  181   b.    
         [0123]    In the fifth embodiment, the body  141  can support the display portion  181  so that the surface on which the LCD  181   a  is provided is directed to the body  141  side as well as the body  141  can support the display portion  181  so that the surface on which the LCD  181   a  is provided is directed to the opposite side of the body  141  side. 
         [0124]    Accordingly, for example, it is possible to allow a person sitting opposite to the operator to view a surface on which the LCD  181   a  of the display portion  181  is provided just by changing the connection of the display portion  181 . 
         [0125]    Also in the fifth embodiment, data is exchanged by the close-range high speed wireless communication by radio, therefore, it is not necessary to connect the body  141  to the display  181  by wire. 
       Sixth Embodiment  
       [0126]    Next, a so-called notebook personal computer  201  according to a sixth embodiment will be explained with reference to  FIG. 8  to  FIG. 10 . 
         [0127]      FIG. 8  shows an appearance example of a notebook personal computer  201  seen from a side surface. 
         [0128]    The notebook personal computer (referred to as a notebook PC in the following description)  201  includes a body  221 , a display portion  222  and a hinge portion  223 . In  FIG. 8 , the notebook PC  201  is in a state in which the body  221  and the display portion  222  meet (in a state in which the body  221  is in contact with the display portion  222 ). 
         [0129]    The body  221  includes, in addition to a keyboard, a touch pad and the like, a coupler  221   b  formed in the same manner as the coupler  21   d  of  FIG. 1  inside the body  221 . 
         [0130]    The display portion  222  includes, in addition to an LCD  222   a,  a coupler  222   b  formed in the same manner as the coupler  22   d  of  FIG. 1  at a portion connected to the hinge portion  223 . 
         [0131]    The body  221  and the display portion  222  are connected to the hinge portion  223 , and the display portion  222  is provided so as to be rotatable about the hinge portion  223  as a rotational axis in a rotational direction shown in  FIG. 8 . That is, the body  221  supports the display portion  222  so as to be rotatable about the hinge portion  223  as the rotational axis. 
         [0132]    Next,  FIG. 9  shows the body  221  to the hinge portion  223  obtained by disassembling the notebook PC  201 . 
         [0133]    The coupler  221   b  of the body  221  and the coupler  222   b  of the display portion  222  are formed so that the positional relation between the coupler  221   b  and coupler  222   b  does not change in the rotational axis direction of the hinge portion  223  even when the display portion  222  is rotated about the hinge portion  223  as the rotational axis in the rotational direction. 
         [0134]    Therefore, the positional relation between the coupler  221   b  and the coupler  222   b  is constantly the same positional relation in the rotational axis direction. 
         [0135]    Accordingly, in the following explanation in the sixth embodiment, only positional relations of the horizontal direction and the vertical direction in  FIG. 8  and  FIG. 10  are considered without considering the positional relation in the normal line direction (rotational axis direction of the hinge portion  223  in  FIG. 9 ) with respect to the drawings of  FIG. 8  and  FIG. 10 . 
         [0136]    When the display portion  222  is in the closed state as shown in  FIG. 8 , transmitting/receiving surfaces of the coupler  221   b  and the coupler  222   b  are arranged in a state in which they are orthogonal to each other, that is, they are not arranged face to face to each other. 
         [0137]    Since the coupler  221   b  and the coupler  222   b  are not arranged so as to face each other, it is difficult to perform the close-range high speed wireless communication, and the close-range high speed wireless communication using the coupler  221   b  and the coupler  222   b  is not started between the body  221  and the display portion  222 . 
         [0138]    Next,  FIG. 10  shows an appearance example of the notebook PC  201  seen from a side surface in a state in which the display portion  222  is opened (a state in which the body  221  is not in contact with the display portion  222 ). 
         [0139]    When the display portion  222  is in the opened state as shown in  FIG. 10 , the transmitting/receiving surfaces of the coupler  221   b  and the coupler  222   b  are arranged at close range so as to face each other. 
         [0140]    In this case, the close-range high speed wireless communication using the coupler  221   b  and the coupler  222   b  is started between the body  221  and the display  222  in response to the arrangement of the transmitting/receiving surfaces facing each other. 
         [0141]    In the sixth embodiment, the coupler  221   b  and the coupler  222   b  are provided so that the transmitting/receiving surface of the coupler  221   b  of the body  221  and the transmitting/receiving surface of the coupler  222   b  of the display portion  222  are arranged so as to be orthogonal to each other when the display portion  222  is in the closed state (the state shown in  FIG. 8 ), as well as so that the transmitting/receiving surface of the coupler  221   b  of the body  221  and the transmitting/receiving surface of the coupler  222   b  of the display portion  222  are arranged so as to face each other when the display portion  222  is in the opened state (for example, the state shown in  FIG. 10 ). 
         [0142]    Accordingly, the notebook PC  201  performs the close-range high speed wireless communication when the display portion  222  is in the opened state to thereby allow the display portion  222  to display a display screen as well as does not perform the close-range high speed wireless communication when the display portion  222  is in the closed state to thereby allow the display portion  222  to display the display screen, therefore, power to be supplied to the display portion  222  can be saved as compared with the case in which the display screen is constantly displayed by the display portion  222 . 
         [0143]    Since data is exchanged by the close-range high speed wireless communication by radio in the sixth embodiment, it is not necessary to connect the body  221  to the display portion  222  by wire. 
       Seventh Embodiment  
       [0144]    Next, a cellular phone device  241  according to a seventh embodiment will be explained with reference to  FIG. 11  to  FIG. 13 . 
         [0145]      FIG. 11  shows an appearance example of the cellular phone device  241  seen from a side surface. 
         [0146]    The cellular phone device  241  includes a body  261  and a display portion  262  which can slide in the right direction (slide direction) in the drawing with respect to the body  261 . In  FIG. 11 , the cellular phone device  241  is in the state in which the display portion  262  is closed (the body  261  is in absolute contact with the display portion  262 ). 
         [0147]    The body  261  includes, in addition to an operation portion  261   a  such as a keyboard, a coupler  261   b  formed in the same manner as the coupler  21   d  of  FIG. 1 . The body  261  supports the display portion  262  so as to slide. 
         [0148]    The display portion  262  includes, in addition to an LCD  262   a,  couplers  262   b,    262   c  formed in the same manner as the coupler  22   d  of  FIG. 1 . 
         [0149]    Next,  FIG. 12  shows an appearance example of the body  261  and the display portion  262  obtained by disassembling the cellular phone device  241 . 
         [0150]    As shown in  FIG. 12 , the coupler  261   b  of the body  261  and the couplers  262   b,    262   c  of the display portion  262  are formed so that the positional relation between the coupler  261   b  and the couplers  262   b,    262   c  does not change in the direction vertical to the slide direction even when the display portion  262  is slid in the slide direction. 
         [0151]    Therefore, the positional relation between the coupler  261   b  and the coupler  262   b  is constantly in the same positional relation in the direction vertical to the slide direction. 
         [0152]    Accordingly, in the following explanation in the seventh embodiment, only positional relations of the horizontal direction and the vertical direction in  FIG. 11  and  FIG. 13  are considered without considering the positional relation in the normal line direction (direction vertical to the slide direction in  FIG. 12 ) with respect to the drawings of  FIG. 11  and  FIG. 13 . 
         [0153]    When the display portion  262  is in the closed state as shown in  FIG. 11 , the transmitting/receiving surface of the coupler  261   b  of the body  261  and the transmitting/receiving surface of the coupler  262   c  of the display portion  262  are arranged so as to face each other at close range. 
         [0154]    In this case, the close-range high speed wireless communication using the coupler  261   b  and the coupler  262   c  is started between the body  261  and the display portion  262  in response to the arrangement of the respective transmitting/receiving surfaces facing each other. 
         [0155]    Next,  FIG. 13  shows an appearance example of the cellular phone device  241  seen from a side surface in a state in which the display portion  262  is in the opened state by allowing the display portion  262  of the cellular phone device  241  of  FIG. 11  to slide in the slide direction (a state in which the body  261  is in contact with the display portion  262  only at a part). 
         [0156]    When the display portion  262  is in the opened state as shown in  FIG. 13 , the transmitting/receiving surface of the coupler  261   b  of the body  261  and the transmitting/receiving surface of the coupler  262   b  of the display portion  262  are arranged so as to face each other at close range. 
         [0157]    In this case, the close-range high speed wireless communication using the coupler  261   b  and the coupler  262   b  is started between the body  261  and the display portion  262  in response to the arrangement of the respective transmitting/receiving surfaces facing each other. 
         [0158]    In the seventh embodiment, when the display portion  262  is in the closed state (the state shown in  FIG. 11 ), the transmitting/receiving surface of the coupler  261   b  of the body  261  and the coupler  262   c  of the display portion  262  are arranged face to face, and when the display portion  262  is in the opened state (the state shown in  FIG. 13 ), the transmitting/receiving surface of the coupler  261   b  of the body  261  and the coupler  262   b  of the display portion  262  are arranged face to face. 
         [0159]    When the respective transmitting/receiving surfaces of couplers are arranged so as to face each other, the close-range high speed wireless communication by radio is performed. 
         [0160]    Therefore, it is not necessary to connect the body  261  and the display portion  262  by wire. 
         [0161]    Incidentally, one coupler  261   b  is provided at the body  261  and two couplers  262   b,    262   c  are provided at the display portion  262  in the seventh embodiment, however, it is also preferable that two couplers are provided at the body  261  and one coupler is provided at the display portion  262 . 
         [0162]    Next, a cellular phone device  281  in which two couplers are provided in the body  261  and one coupler is provided in the display portion  262  will be explained with reference to  FIG. 14 . 
       Eighth Embodiment  
       [0163]      FIG. 14  shows an appearance example of the cellular phone device  281  seen from a side surface according to an eighth embodiment. 
         [0164]    In the cellular phone device  281 , the same signs are given to components formed in the same manner as the cellular phone device  241  according to the seventh embodiment, therefore, explanation thereof will be omitted below. 
         [0165]    That is, the cellular phone device  281  is formed in the same manner as the cellular phone device  241  except that a coupler  301  is newly provided at the body  261  as well as a coupler  321  is provided instead of the couplers  262   b,    262   c  at the display portion  262 . 
         [0166]    When the display portion  262  is in the closed state in the cellular phone device  281 , the coupler  301  of the body  261  is arranged face to face with the coupler  321  of the display portion  262 , so that the close-range high speed wireless communication can be performed. 
         [0167]    On the other hand, when the display portion  262  is in the opened state in the cellular phone device  281 , the coupler  261   b  of the body  261  and the coupler  321  of the display portion  262  are arranged face to face, so that the close-range high speed wireless communication can be performed. 
       9. Modification Example  
       [0168]    In the second and third embodiments, the couplers  61   c,    61   d  are provided at edge portions of the body  61  and the couplers  62   d,    62   e  or the coupler  101  are provided at a corner portion of the display portion  62 , however, it is not limited to this. 
         [0169]    For example, it is preferable that one coupler is provided at the center of the convex portion  61   b  instead of the couplers  61   c,    61   d  in the body  61 , and couplers are provided inside the concave portions  62   b,    62   c  respectively, instead of the couplers  62   d,    62   e  or the coupler  101  in the display portion  62 . 
         [0170]    In the above case, two couplers in the body  61  can be reduced to one. 
         [0171]    In the first, second embodiments as well as the fourth to eighth embodiments, the close-range high speed wireless communication is performed when the respective transmitting/receiving surfaces of the couplers are arranged face to face (the angle formed by the respective transmitting/receiving surfaces is 0 degree), and in the third embodiment, the close-range high speed wireless communication is performed when the angle formed by the respective transmitting/receiving surfaces of the couplers is 45 degrees, however, it is not limited to these. 
         [0172]    That is, it is possible to perform the close-range high speed wireless communication when the respective transmitting/receiving surfaces of the couplers are arranged in a position in which the close-range high speed wireless communication can be performed (for example, a position in which the angle formed by the respective transmitting/receiving surfaces of the couplers is 0 or more and less than 90 degrees). 
         [0173]    In the first to eighth embodiments, cases in which the invention is applied to a personal computer and a cellular phone have been explained, however, the invention can be applied to any information processing device as long as the device includes a display integrally. 
         [0174]    Embodiments are not limited to the above first to eighth embodiments, and can be variously changed within a scope not departing from the gist of the invention. 
         [0175]    It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and alterations may occur depending on design requirements and other factors insofar as they are within the scope of the appended claims or the equivalents thereof.
