The transmission signal processing circuit 31 and the reception signal processing circuit 55 may process the sound in an analog manner, but preferably perform the editing process using the phoneme segments. Reference numeral 6 denotes a control circuit, which includes the transmission signal processing circuit 31, the reception signal processing circuit 55, and the transmission mixer 33 described above.
And frequency synthesizer 42 connected to reception mixer 52
, The sound of the microphone 3 is substantially output, and the sound is reproduced from the received signal to level the speaker 5. The control means 6 comprises a microcomputer or a gate array, and also controls the liquid crystal display 1 and the input means 2. Such components are housed in a single box and can be used as a so-called mobile phone. However, a slot 7 having a built-in connection terminal is provided on the back surface so that a card-type additional device or the like can be connected. I have.

Reference numeral 8 denotes a current position detecting means which receives a signal from, for example, a satellite, calculates the current position, and outputs information such as longitude and latitude (GPS).
ngSystem) and a geomagnetic sensor. This current position detecting means 8 is provided detachably with respect to the main body, and is substantially L-shaped so as not to interfere with the antenna 4 necessary for telephone communication such as voice and to expose the GPS antenna section 81. It is inserted into the slot 7 and connected to the control means 6. The current position detecting means 8 is turned on by a signal from the control means 6, calculates the current position under the control of the control means 6 and outputs the current position information as a digital signal, and the output information is modulated. Vessel 3
2, transmitted via the transmission mixer 33 and the like.

On the other hand, the control means 6 has a hands-free answering function for automatically receiving a call in the automatic call receiving mode, and further receives a signal by operating a specific key from the input means 2 or a reception processing circuit. Upon receiving the signal of the specific key from 55, power is supplied to the current position detecting means 8, and information on the current position is output from the antenna. That is, the transmission signal processing circuit 31 and the reception signal processing circuit 55 do not edit the tone signals of “#” and “*” indicating the digital signal and the tone signals of the numbers following them using the phoneme segments. Control means 6 when received
Output the playback signal. Then, after the telephone line is connected, the current position information is output according to the output of the current position detecting means 8 by the tone signals “#”, “9”, and “9”.
