  The wireless communication unit 101 transmits and receives information to and from the wireless base station via the call antenna 118. The camera unit 102 acquires (photographs) image information. The voice processing unit 103 performs processing of a voice signal input to the transmission microphone 104 and a voice signal for causing the reception speaker 105 or the notification speaker 112 to output voice.

  The LED 109 emits light when an incoming call is received (when a call is received or an e-mail is received), or for a preset time.

  Based on the detection result of the sensor 116, the state detection unit 110 detects whether the mobile communication terminal 100 is in an open state or a closed state, and the front direction of the first housing 121. The sensor 116 is realized by a push switch or a hall element, for example.

  Specifically, in the state detection unit 110, whether the mobile communication terminal 100 is in an open state or the front of the first housing 121 (that is, the display unit 106) is opened to the outside of the mobile communication terminal 100 in the closed state. In a closed state (hereinafter referred to as a first closed state), or a state in which the front surface of the first housing 121 (that is, the display unit 106) is hidden inside the mobile communication terminal 100 in the closed state ( Hereinafter, the second closed state is detected).

  Note that the state detection unit 110 is provided at a position corresponding to the convex portion in the other casing, for example, by a convex section provided in one casing of the first casing 121 or the second casing 122. Whether the portable communication terminal 100 is in an open state or a closed state is detected depending on whether or not the push switch has been pressed.

  In the closed state, the state detection unit 110 corresponds to, for example, a Hall element provided in one casing of the first casing 121 or the second casing 122 corresponding to the Hall element in the other casing. Whether the first closed state or the second closed state is detected is detected depending on whether or not magnetism is detected by the magnet installed at the position to be operated.

  The strap determination unit 111 determines whether the strap 200 is connected to the strap socket 117 and the type of the connected strap 200 when determining that the strap 200 is connected.

  The storage unit 113 stores information on the phone book, information on sent and received mails, information on the telephone number of the other party that made and received calls, information received via the Internet, information on installed application programs, The captured image and the settings of the mobile communication terminal 100 are stored.

  The broadcast receiving unit 115 demodulates the television broadcast signal and processes broadcast signals such as video data, audio data, and information data. The television broadcast signal is received by a television broadcast receiving antenna mounted on the strap 200.

  The control unit 114 controls each unit to cause the mobile communication terminal 100 to realize a telephone communication function, an e-mail transmission / reception function, an Internet connection function, a camera function, a television broadcast reception function, a content reproduction function, and the like.

  FIG. 3 is a flowchart showing the operation of the mobile communication terminal 100 of the present embodiment. As shown in FIG. 3, the control unit 114 of the mobile communication terminal 100 is connected when the strap determination unit 111 determines that the strap 200 is connected to the strap socket 117 (Y in step S101). The type of the strap 200 is determined (step S102).

  Then, the control unit 114 determines whether the state (open state, first closed state, or second closed state) of the mobile communication terminal 100 detected by the state detection unit 110 depends on the type of the strap 200 determined in step S102. If it is in the state (Y in step S103), the function corresponding to the strap 200 is activated (step S104).

  Specifically, for example, when the strap 200 connected to the strap socket 117 is equipped with a television broadcast receiving antenna and parts for realizing an operation function corresponding to the television broadcast, the control unit 114 is When the mobile communication terminal 100 is in the first closed state, components received on the strap 200 are utilized to cause the broadcast receiving unit 115 to demodulate the received television broadcast signal and display the video on the display unit 106. And the sound is output to the notification speaker 112 (each unit is controlled so as to realize a television broadcast receiving function).

  Further, for example, when a component storing user identification information is mounted on the strap 200 connected to the strap socket 117, the control unit 114 performs the user identification when the mobile communication terminal 100 is in the open state. Each unit is controlled so as to realize a user's e-mail transmission / reception function according to information.

  When the strap 200 is separated from the strap socket 117 (that is, the strap 200 is removed from the strap socket 117) (Y in step S201), the control unit 114 executes (activates) the control according to the strap 200. If it is present (Y in step S202), the control (function) is terminated (step S203).

  According to the present embodiment, the function according to the component mounted on the strap 200 is realized by the control of the control unit 114. Therefore, since it is not necessary to mount a component for realizing the function on the mobile communication terminal 100, the mobile communication terminal 100 can be reduced in size.

  Further, when the state (the open state, the first closed state, or the second closed state) of the mobile communication terminal 100 detected by the state detection unit 110 is a state according to the type of the strap 200, the control unit 114 Further, since the function corresponding to the strap 200 is activated, the convenience and operability for the user can be improved.

  In addition, when the strap 200 is separated from the strap socket 117 (that is, when the strap 200 is removed from the strap socket 117), the control unit 114 performs the control according to the control according to the strap 200. Since it is configured to end, it is possible to prevent the control from continuing after the strap 200 is removed from the strap socket 117.

  In addition, since the navigation operation unit 108 is provided in the connecting unit 123, the second casing can be downsized and the mobile phone excellent in design without reducing the size of each key of the operation unit 107 and deteriorating operability. A communication terminal can be provided. Note that the control unit 114 determines whether or not to operate based on the operation performed on the m navigation operation unit 108 and the state of the mobile communication terminal 100 detected by the state detection unit 110 according to the content of the operation performed ( (Open state, first closed state, or second closed state). In such a configuration, the convenience and operability for the user can be improved.
