Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cellular phone mainly used for a mobile phone, a car phone, etc. and having a built-in low power radio function.

[0002]

2. Description of the Related Art Conventionally, this type of cellular telephone has a handset transmitting / receiving device in addition to the cellular telephone device. When making a call using a cellular telephone, the user presses the handset handset on one ear to make a call. In order to obtain a hands-free function in this cellular telephone, a separate hands-free transmitter / receiver device is connected to the cellular telephone device by a cord.

Incidentally, for example, Japanese Patent Laid-Open No. 61-177830.
As a well-known mobile phone system, the publication discloses a technique of using a mobile device and a cordless phone in combination by an incoming call connection.

[0004]

In the case of the above-mentioned cellular telephone, if the cellular telephone is used with the hands-free function, the cellular telephone and the hands-free transmitter / receiver must be connected by a cord, and the handling is complicated. There is a problem.

Further, since it is necessary to push the handset transmitter / receiver device to one ear during a call, an electromagnetic wave with a large transmission output is radiated to the caller at a short distance from the antenna connected to the cellular phone device. There is a risk of adversely affecting (user) health.

The present invention has been made to solve the above problems, and its technical problem is that the wireless function is simple in handling, safety is ensured during a call, and usage cost can be improved. It is to provide a built-in cellular telephone.

[0007]

According to the present invention, a wireless function in which a second wireless device capable of communicating with a first wireless device provided in another telephone communication device is built in together with a cellular phone device. A built-in cellular telephone is obtained.

Further, according to the present invention, in the above-mentioned cellular phone with built-in wireless function, the other telephone communication device is a wireless function built-in handset including the first wireless device and the handset handset. The built-in type cellular telephone or another telephone communication device can be obtained as a built-in wireless function type cellular telephone which is a hands-free unit having a built-in wireless function, in which the first radio unit is built in together with the hands-free handset.

Further, according to the present invention, in any one of the above-mentioned cellular phones with a built-in wireless function, the first wireless device,
And each of the second wireless devices is a low-power type cellular phone with built-in wireless function.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The cellular phone with a built-in wireless function of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a basic configuration of a telephone communication system in which a cellular telephone with a built-in wireless function according to an embodiment of the present invention is combined with another telephone communication device.

This telephone communication system includes a cellular phone 7 with a built-in wireless function, a hands-free unit 8 with a built-in wireless function and another handset (a handset with a built-in wireless function) 9 as other telephone communication devices. Made of

Of these, the cellular phone 7 with a built-in wireless function is configured by providing the cellular phone device 1 with a low power wireless device 2 having a communication range of about 2 m. The wireless function built-in hands-free unit 8 is configured by providing the hands-free transceiver 3 with a low-power wireless device 4. Furthermore,
The wireless function built-in handset 9 is configured by providing a low power wireless device 6 in the handset transmitting / receiving device 5.

With such a configuration, the low-power wireless device 2 included in the cellular phone 7 with built-in wireless function has the low-power wireless device 6 included in the handset 9 with built-in wireless function and the hands-free device with built-in wireless function. Both can communicate with each other with the low power radio device 4 provided in the unit 8. In this case, the small power wireless device 6 and the small power wireless device 4 are regarded as the first small power wireless device provided in another telephone communication device, and the small power wireless device 2 is regarded as the second small power wireless device. And the second low power wireless device is capable of communicating with the first low power wireless device.

Therefore, the cellular phone 7 with a built-in wireless function is provided.
Can perform cordless wireless communication with a small amount of power between the wireless function built-in hands-free unit 8 and the wireless function built-in handset 9.

[0016]

As described above, according to the cellular telephone with a built-in wireless function of the present invention, the handset transmitting / receiving device provided in the conventional cellular telephone is provided separately, and instead of this, the cellular telephone device has a small power consumption. Since the wireless device is provided, it is possible to perform cordless wireless communication with other telephone communication devices, that is, a small power wireless device provided in a wireless function built-in handset or a wireless function built-in hands-free unit with small power. become able to. As a result, when using with the hands-free function, there is no need to connect a cord as in the past, and it is not necessary to press the handset transmitter / receiver on one ear even during a call, ensuring easy handling and safety during a call. In addition, it is possible to provide a cellular phone with a built-in wireless function that can improve the usage cost.
