Thereby, the complexity of the operation when the various additional function units 2 are connected can be eliminated.

Then, when the user performs a receiving operation using the operation unit 15 of the mobile phone main body 1, a call is started. The transmission sound after the start of the call is converted (modulated) by the voice codec of the transmission / reception unit 12 into a communication format that matches the communication line, and communication via the base station is performed.
It should be noted that the circuit configuration of the mobile phone device of the present invention is not limited to the above-described configuration, and it is obvious that another configuration having the same function may be used.

In the portable telephone device of the present invention described above,
The following specific effects can be obtained. First, other functions can be easily added to the mobile phone device when not used as a telephone, and the mobile phone device can be effectively used. Secondly, by using a standardized common interface as an interface in the mobile phone device of the present invention, various additional function units can be exchanged and used. Third, the menu such as the jog dial can be automatically limited by the identification means, and the operation can be simplified. Fourth,
Since the jog dial is used to select a radio receiver, to select visible radio character information, and to control additional function units such as scrolling, the convenience of the user can be improved.

The present invention is not limited to the above embodiment,
Various embodiments can be employed. Although the mobile phone device using the earphone microphone is illustrated in the above embodiment, the present invention is also applied to an in-vehicle mobile phone device or a cordless phone having a predetermined hands-free function,
The present invention is not limited to the shape and system of the mobile phone device.
In addition, it goes without saying that the present invention can be developed in various forms without being limited to the embodiment described above.

[0030]

According to the portable telephone device of the present invention described above, a new additional function can be easily added to the portable telephone body by connecting the additional function means to the portable telephone body. Thereby, the mobile phone device can be effectively used. Further, in the mobile phone device of the present invention, since the additional function unit is identified by the identification means and only the necessary operation menu is displayed on the display means, the operation is complicated when various additional function units are connected. Can be eliminated, which is beneficial.
