  FIG. 2 is a block diagram showing the configuration of an open / close communication terminal apparatus according to the present invention. For example, the present invention is applied to a mobile terminal apparatus of IS-95 (Interim Standard 95) based CDMA (Code Division Multiple Access) mobile phone. Shows the case. In addition, about the structure which overlaps with FIG. 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted. However, the communication system is not limited to the CDMA system, and any of PDC (Personal Digital Cellular) and PHS (Personal Handyphone System) may be used.

  As is clear from FIG. 2, the switchable communication terminal apparatus 1 includes an antenna 15, a transmission / reception unit 21, a modulation / demodulation unit (that is, including a baseband processing unit) 22, an audio processing unit 24, a microphone 9, a receiver 16, and a control. The configuration includes a unit 20, a main display unit 2, a sub display unit 18, a camera unit 25, a camera I / F 26, and an operation unit 23.

  The control unit 20 includes, for example, a microprocessor, a ROM (Read Only Memory) 20a, a RAM (Random Access Memory) 20b, and the like, and performs various controls according to a control program stored in the ROM 20a. The RAM 20b stores information to be transmitted, received information, phone book data (for example, data for 999 memory dials), etc. temporarily or until an erase / change operation is performed. .

  The main display unit 2 and the sub display unit 18 correspond to the main display 2 and the sub display 18, respectively.

  The operation unit 23 includes a flexible key 3, a 4-contact key 4, an e-mail key 5, an OK key 6, an end / power key 7, a numeric keypad 8, a WEB key 11, a side key 12, a start key 14, and an open / close detection switch 19. Is done.

  In the open / close communication terminal apparatus 1 having the above configuration, the received radio wave is received by the transmitting / receiving unit 21 via the antenna 15 and demodulated by the modem unit 22. The audio information demodulated by the modem unit 22 is supplied to the audio processing unit 24, subjected to predetermined processing by the audio processing unit 24 under the control of the control unit 20, and then subjected to electro-acoustic conversion by the speaker 16. And output as audio.

  The received data demodulated by the modem unit 22 is supplied to the control unit 20. This received data consists of control data, character data, etc. (for example, the other party's telephone number) and image data, etc., and is supplied to the main display unit 2 and sub display unit 18 as necessary and displayed as character information or image information. Stored in the RAM 19a. The control data of the received data includes incoming information of voice communication (including the caller's telephone number), incoming information of e-mails and text messages transmitted by the SMS bearer (short message bearer) method, etc. Is also included.

  On the other hand, the input sound is subjected to acoustic-electric conversion by the microphone 9, subjected to predetermined processing by the sound processing unit 24, and then supplied to the modulation / demodulation unit 22.
