FIG. 4 shows the control of the second display unit 107 and the second operation unit 110, and FIG. 5 shows the control of the first operation unit 109. These controls are realized by the control unit 116 reading and executing a control program stored in the storage unit 115 in accordance with the state of the mobile communication terminal device detected by the state detection unit 111.

  When the open / close sensor 113 detects that the mobile communication terminal device is in the open state, that is, the second unit 2 is opened with respect to the first unit 1 in the rotation operation of the coupling unit 3 (Yes in step S101), the control unit 116. Disables the second display unit 108 and the second operation unit 110. That is, the display of the second display unit 108 is turned off, the input operation using the touch panel of the second display unit 108 is not accepted, and the second operation unit 110 is set not to accept the user's input operation (step S105). .

  When the mobile communication terminal device is in the open state, it is assumed that the user uses the first display unit 107 and the first operation unit 109. In such a case, the display on the second display unit 108 is turned off by the above-described control, so that unnecessary power consumption is suppressed, and malfunction caused by the user touching the touch panel of the second display unit 108 unintentionally. can avoid. Further, by invalidating the operation on the second operation unit 110, erroneous input caused by the user unintentionally touching the second operation unit 110 can be avoided.

  The open / close sensor 113 detects that the mobile communication terminal device is in the closed state, that is, the second unit 2 is closed with respect to the first unit 1 in the rotation operation of the coupling unit 3 (No in step S101), and the coupling unit 3, when the slide sensor 112 detects that the second unit 2 is extended with respect to the first unit 1 (step S <b> 102 Yes, states of FIGS. 2A and 2B), the control unit 116. Enables the second display unit 108 and disables the second operation unit 110.

  When the mobile communication terminal device is slid in the closed state, it is assumed that the user looks at the display screen of the second display unit 108 and performs touch panel input of the second display unit 108. In the control described above, in such a case, erroneous input due to the user unintentionally touching the second operation unit 110 can be avoided.

  When the mobile communication terminal device is in the closed state (step S101 No) and in the non-stretched state (step S102 No, the states of FIGS. 1B, 1C, and 1E), the control unit 116 is the second display unit. 108 and the second operation unit 110 are enabled. That is, information is displayed on the display screen of the second display unit 108, an input operation using the touch panel of the second display unit 108 is accepted, and an input operation for the second operation unit 110 is accepted (step S103). .

  When the mobile communication terminal device is in a closed state and a non-extension state, it is assumed that the user looks at the display screen of the second display unit 108 and performs an input operation using the touch panel of the second display unit 108 and the second operation unit 110. Is done. Such an operation is accepted by the above control.

  Next, the control of the first operation unit 109 will be described with reference to FIG. When the slide sensor 112 detects that the mobile communication terminal device is in the non-extended state (step S201 No), and when the open / close sensor 113 detects that it is in the closed state, no new control is performed. Or in this state, since the 1st display part 107 is closed and it cannot access from a user, the display of the 1st display part 107 is turned off for power saving.

  When the slide sensor 112 detects that the mobile communication terminal device is in the non-extended state (step S201 No) and the open / close sensor 113 detects that the mobile communication terminal device is in the open state (step S202 Yes), the control unit 116 controls the first operation unit 109. Is set to the QWERTY mode (step S203).

  When the mobile communication terminal device is in the non-extended state and in the open state, it is assumed that the user uses the first operation unit 109 while looking at the first display unit 107. Moreover, since the first operation unit 109 is fully opened compared with the case where the slide is extended, it is assumed that a more complicated input function such as character input is used. By the above operation, the user can perform such complicated input using the input device in the QWERTY mode.

  When the mobile communication terminal device is in the extended state (step S201 Yes) and in the closed state (step S204 No), the control unit 116 sets the first operation unit 109 to a numeric keypad mode that allows numerical input (step S205).

  When the mobile communication terminal device is in the extended state and in the closed state, the user performs an input operation using an input device (such as a numeric keypad) in a partial area exposed by sliding the first operation unit 109 while looking at the second display unit 108. It is envisaged to do. By the above operation, the user can perform an input operation using the input device automatically set to the numeric keypad mode.

  A part of the keys of the QWERTY keyboard set in step S203 may also serve as the numeric key set in step S205. In this case, the key assigned to the predetermined alphabet in step S203 is reassigned to the predetermined number in step S205.

  When the mobile communication terminal device is in the extended state (step S201 Yes) and in the open state (step S204 Yes), the control unit 116 invalidates the input of the first operation unit 109 (step S206).

  When a user wants to concentrate on viewing a broadcast program received by the broadcast receiving unit 102 or an image stored in the storage unit 115, it is possible to avoid unintentionally touching the mobile communication terminal device and preventing viewing of the image. It is desirable. By the above operation, when the user wants to concentrate on viewing the video, the input unit is locked by sliding the second unit 2 in the open state, thereby preventing viewing from being hindered by an erroneous operation. it can.
