[0002]

2. Description of the Related Art In recent years, automobile telephones have become extremely popular, and in addition to conventional handset telephones, hands-free telephones have been developed in order to avoid one-handed driving during the operation of the handset.

[0003] This type of hands-free telephone set is
A microphone for transmission is installed in, for example, a sun visor section, and an ON / OFF switch for transmission and reception is installed in, for example, a steering wheel section.
Since the dedicated speaker or the in-vehicle audio speaker is also used, the driver can talk without releasing the hand from the steering wheel.

[0004] In this case, since a car-dedicated telephone cannot be used once leaving the car, a conventional general-purpose portable telephone is configured to be connectable to a hands-free set telephone device. At that time, a mobile phone that can be used has been proposed.

[0005] Such a hands-free set type mobile phone system is configured such that a hands-free set housing is mounted in a seat side box of a center console or on a lid of the seat side box, and a mobile phone is set therein. Have been.

[0006]

However, in the conventional hands-free set car telephone system, there are (1) restrictions on the installation location, and (2) a harness or hands-free set for connecting the hands-free set to a vehicle power supply. There have been various problems such as a need for a harness for connecting to a mobile phone, and (3) a complicated device and high cost.

That is, in the conventional device, the hands-free set is stored in the seat side box of the center console or tied to the lid, so that the seat side box cannot be used, and the shape of the seat side box differs depending on the vehicle type. Therefore, it is difficult to firmly fix it, or a special part for mounting is required separately, which causes an increase in cost.

Further, when the hands-free set is mounted on the lid of the seat side box, the signal wiring harness is exposed, and there is a problem that the interior is not organized and the appearance is poor. Since the user needs to operate the device facing sideways, the operability is poor.

The present invention has been made in view of such problems of the prior art, and is compact, inexpensive, hands-free set excellent in versatility, storage and safety, and a telephone system using the same. The purpose is to provide.
