2. Description of the Related Art In recent years, data communication, for example, personal computer communication, has been actively carried out through a public line by using an information processing device such as a personal computer and a data communication modem. In this case, the personal computer is connected to the public line via the data communication modem and telephone.

In this structure, when data communication is being executed, the public line used is used only for data communication and cannot make a call. Therefore, in order to talk to the other party of the data communication, the data communication is terminated,
After disconnecting the line, it is necessary to call the other party again and make the call ready. On the contrary, in order to perform data communication with the callee, it is necessary to disconnect the line, call the caller again, and perform connection processing with the data communication modem of the callee.

By the way, in recent years, data communication using mobile communication is also performed. In this case, the personal computer is connected to the public line via the data communication modem, mobile station, and base station. Here, as mobile communication, consider a cordless handset (mobile station) and a base unit (base station) of a cordless telephone as an example. In this configuration, for example, the microphone / earphone jack provided in the cordless cordless handset and the modular jack of the data communication modem are connected by a dedicated cable. The output signal from the data communication modem is input to the cordless slave unit and transmitted to the master unit via the communication channel established between the master unit and the slave unit.

In this configuration, when data communication is being executed, the public line being used is used only for data communication and cannot make a call. Therefore, in order to talk to the other party of PC communication, you can end the data communication, disconnect the line, disconnect the dedicated cable from the microphone / earphone jack, and call the other party again. Need to be in good condition. That is,
In the normal cordless cordless handset configuration, when the dedicated cable is connected to the microphone / earphone jack, the signal from the speaker / microphone provided in the cordless cordless handset is blocked so that noise (unnecessary signal) does not enter. This is because it is configured.

Further, when using mobile communication such as a cordless telephone, it is necessary to establish a communication channel between the mobile station and the base station. In a cordless telephone, when making a call from a cordless cordless handset to a party connected to a public line, first, an "outside line button" of the cordless cordless handset is pressed.
When the "outside line button" is pressed, a communication channel between the cordless parent and child units is established, and a public tone line is connected to generate a dial tone. Here, when the dial button is pressed, the cordless slave device transmits the input telephone number to the cordless master device according to a special protocol (local command) defined between the master and slave devices.

Generally, a cordless telephone communicates if the telephone number of the other party is not input from the "dial button" for a predetermined time or longer after the "outline button" is pressed and the communication channel between the cordless parent and child units is established. It is configured to force a disconnect to release the channel. In other words, in order to enter the communication (call) state with the public line through the cordless parent and child units, first press the "outside line button" provided on the cordless child unit, and then use the "dial button" for the destination telephone number. It needs to be pushed.

[0008]

As described above, in the conventional communication system, the cordless slave unit (mobile station), the master unit (base station), and the other party connected via the public line are used for data communication or communication. You can only do one of the
In order to make a call or data communication with the same party, it is necessary to make a call again.

Further, since a dedicated cable is connected to the microphone / earphone jack of the cordless cordless handset and a signal from the data communication modem is input, a dedicated cable is used every time data communication and a call are made. I had to attach and detach the cable.

Further, even when performing data communication, it can be used under a communication state established by manually operating a button provided on the cordless slave unit (connection between the master unit and the slave unit, connection with the partner). Therefore, the operability was poor.

The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a telephone with a wireless communication function, which enables simple and effective data communication and telephone communication.
