  First, when the user operates the power / end button 10 of the key input unit 108 to turn on the power, the control unit 107 performs an initial check, and if there is no abnormality, the base station and the base station are required according to a predetermined communication protocol. Information is exchanged, location registration is performed, and a standby state is entered.

  In this standby state, the control unit 107 monitors whether it is called by connecting to a control channel (calling channel for call number) assigned at a predetermined time interval (detects its own identification number intermittently). On the other hand, in an unmonitored state, power supply to unnecessary circuits is stopped to save power. When the control unit 107 detects its own identification number on the control channel and connects to the call channel according to a predetermined connection procedure (connection protocol) with the base station, the user can talk to the calling party. Since the connection protocol is well known and is not directly related to the present invention, detailed description thereof is omitted.

  3A and 3B are external views of the mobile phone according to the present invention. FIG. 3A is a normal posture in a closed state, FIG. 3B is a left lateral posture, FIG. 3C is a right lateral posture, and FIG. 3 (D) is a fall posture.

  In the standby state described above, the user operates the key input unit 108 with the normal posture shown in FIG. 3A (the operation that keeps pressing the TV button 7 for one second or more) to select and receive a one-segment TV program that is a terrestrial digital broadcast. .

  The control unit 107 recognizes that the current state is a normal posture based on the posture data output from the posture sensor 116, and broadcast data of the TV program designated by the TV tuner unit 105 via the data bus. Is temporarily stored in the RAM 110b, and the video of the TV program is normally displayed on the external display device 109a based on the video data (that is, the upward direction of the mobile phone body 1 and the upward direction of the video are displayed). . As an example, it is assumed that a wedding TV program (video and audio in which a bride's wedding dress is walking with two children) is playing.

  When the user tilts the mobile phone body 1 90 ° to the left from the normal posture in FIG. 3A, the control unit 107 determines that the current state is the left side posture based on the posture data output from the posture sensor 116. In addition, the television image normally displayed on the outer surface display device 109a is rotated 90 ° to the right (see FIG. 3B).

  On the other hand, when the user tilts the mobile phone body 1 to the right by 90 ° from the normal posture in FIG. 3A, the control unit 107 determines that the current state is the right side posture based on the posture data output from the posture sensor. And the TV image normally displayed on the outer surface display device 109a is rotated 90 ° to the left (see FIG. 3C).

  Further, when the user rotates the mobile phone body 1 by 90 ° from the left side posture in FIG. 3B or the right side posture in FIG. 3C, the control unit 107 outputs the posture output from the posture sensor 116. Based on the data, it is recognized that the current state is the falling posture, and the television image normally displayed on the outer surface display device 109a is further rotated by 90 ° (see FIG. 3D).

  Next, the TV image switching operation when the openable communication terminal device according to the present invention is changed from the closed state to the open state will be described in detail for the case where the user sets the posture sensor output to be valid / invalid. . It should be noted that the validity / invalidity of the attitude sensor output is simply selected according to the user's preference in the function setting, and the selection operation is not directly related to the present invention and will not be described.

Example 1 (when posture sensor output is disabled):
4A and 4B are external views of the mobile phone according to the present invention, in which FIG. 4A shows a closed state and FIG. 4B shows an open state. FIG. 4C shows a state where FIG. 4B is viewed from the left. Note that, since the posture sensor output is set to be invalid, the control unit 107 performs display control as follows regardless of the posture of the foldable mobile phone body 1.

  When the user slides the slide button 21 to remove the lock claw and opens the upper housing 1a from the normal posture in which the TV image of FIG. 4A is normally displayed as in FIG. 3A, the control unit 107 is opened. Recognizes from the closed state to the open state by the output signals from the closed state detection switch 23 and the open state detection switch 24, and erases the TV image normally displayed on the external display device 109a. Then, the television program displayed on the lower inner display device 109c is rotated 90 ° to the left and enlarged to fill the screen (see FIG. 4B).

  In addition, the control unit 107 displays an operation screen of a television program on the upper inner surface display device 109b which is a touch panel (see FIG. 4C). When the user inputs operation information by touching the upper inner display device 109b, the television program is switched and displayed based on the operation information.

  5A and 5B are external views of the mobile phone according to the present invention, in which FIG. 5A is in a closed state, FIG. 5B is in an open state, and FIG. 5C is a fully open state. Yes.

  When the upper casing 1a is opened from the normal posture in which the TV image of FIG. 5A is normally displayed as in FIG. 4A, the TV image normally displayed on the external display device 109a is erased. As shown in FIG. 5B, which is the same as FIG. 4B, the television program displayed on the lower inner surface display device 109c is rotated 90 ° to the left and enlarged to the full screen. Similarly to FIG. 4C, the control unit 107 displays the operation screen of the television program on the upper inner surface display device 109b which is a touch panel.

  When the user completely opens the upper housing 1a, the control unit 107 confirms that the open state is completely opened by the output signals from the closed state detection switch 23 and the open state detection switch 24. At the same time, the TV program displayed on the lower inner surface display device 109c is rotated 90 ° to the right, and is enlarged and displayed on both screens across the upper inner surface display device 109b and the lower inner surface display device 109c.
