Next, the operation of the above-described portable telephone will be described. First, the user selects a switch mode / antenna mode in advance. Here, the switch mode is a mode in which a telephone is turned on / off by an off-hook switch 31 and an on-hook switch 32 (FIG. 2) on an operation panel, and is the same mode as a conventional mobile phone. On the other hand, the antenna mode is a mode peculiar to the mobile phone according to the present embodiment. The antenna mode is in an off-hook state when the antenna 16 is extended to the highest position, and is in an on-hook state when the antenna 16 is contracted to the lowest position.

Now, when the user performs an operation of selecting a switch mode using the ten keys and function keys on the operation panel, the CPU 11 detects this and issues a selection command for selecting the switches 31 and 32 to the interface 36 of the operation unit 14 (see FIG. Output to 3). Interface 3
6 receives this command and outputs to the selector 35 a selection signal SE for selecting the switches 31 and 32. Selector 35
Receives the selection signal SE and outputs the outputs of the switches 31 and 32 to the interface 36. Thereafter, just like the conventional mobile phone, when the switch 31 is pressed, an off-hook operation is performed, and when the switch 32 is pressed, an on-hook operation is performed. In this case, the switches 33 and 34 have no relation to the circuit operation.

Next, when the user performs an operation of selecting an antenna mode by using the ten keys and function keys on the operation panel, the CPU 11 detects this and sends a selection command to select the switches 33 and 34 to the interface 36 of the operation unit 14. Output. The interface 36 receives this command and receives a selection signal S for selecting the switches 33 and 34.
E is output to the selector 35. The selector 35 receives the selection signal SE and outputs the outputs of the switches 33 and 34 to the interface 36. Thereafter, the switch 33 functions as an off-hook switch, and the switch 34 functions as an on-hook switch. That is, when the antenna 16 is extended to the uppermost position, an off-hook operation is performed, and the antenna 1
When 6 is reduced to the lowest position, an on-hook operation is performed.

When the user makes a call in the state where the above-described antenna mode is selected, first, the user inputs the telephone number of the other party using the operation unit 14. When the telephone number is input, the CPU 11 writes the telephone number into the RAM 13 once. Next, the user sets the antenna 16
To the top position. When the antenna 16 is extended to the highest position, the switch 33 (FIG. 3) is turned on,
The off-hook is notified to the CPU 11. Upon receiving this notification, the CPU 11 outputs the telephone number in the RAM 13 to the communication unit 18. The communication unit 18 transmits the telephone number on a carrier wave. When the transmitted telephone number reaches the telephone office via the public line and the line is connected, the communication unit 18
In addition, a call using the microphone 21 and the speaker 22 via the voice processing unit 20 is performed with the other party.

When an incoming call arrives, the communication section 18 demodulates the incoming signal received via the antenna 16 and outputs the obtained incoming data to the CPU 11. The CPU 11 receives the incoming data, stores the telephone number of the caller included in the incoming data in the RAM 13, and then outputs a ring tone generation command to the ring tone generating unit 23. The ring tone generator 23 receives this command, forms a ring tone,
Output to As a result, an incoming melody is generated from the speaker 24.

When the user of the portable telephone hears the incoming melody and extends the antenna 16 to the uppermost position, the switch 33 is turned on. When the switch 33 is turned on, C
The PU 11 detects this, outputs a ring tone stop command to the ring tone generating unit 23, and outputs a line connection instruction to the voice processing unit 20 and the communication unit 18. Thereafter, the line is connected to the caller, and the voice signal of the microphone 21 is transmitted to the caller. Further, an audio signal based on the audio data from the transmission source is output from the audio processing unit 20 to the speaker 22, and the speaker 22 emits a sound. In the above embodiment, the switch 33 that is turned on when the antenna 16 is extended to the uppermost position and the switch 34 that is turned on when the antenna 16 is retracted to the lowermost position are provided.
The switch 3 may not be provided, and only the switch 34 may be provided. In this case, when the switch 34 is turned off, it is detected to perform off-hook processing, and when the switch 34 is turned on, it is detected to perform on-hook processing.
