After that, if a telephone number is input from the key input unit 2 in the handset main body 1 in the same manner as a normal wired telephone, the input telephone number is displayed on the display unit 6. Thereby, the user confirms whether or not there is an error, and then pushes the call button (this operation is performed using the key input unit 2). Thereby, the multi-frequency signal corresponding to the telephone number input in the slave unit is modulated into a high frequency, and the slave unit makes a call. After that, the high-frequency signal received by the antenna 3 is demodulated into a voice signal, so that the user can hear using the speaker 5. Also, a voice signal input using the microphone 4 is similarly modulated into a high frequency signal and transmitted via the antenna 3, whereby a normal call becomes possible. After the call ends, the call is completed by pressing the off button.

Next, the case of receiving an incoming call will be described.
In this case, first, it is necessary to connect the charged secondary battery 7 to the slave unit main body 1 and turn on the power of the slave unit main body 1 to keep the standby state (this operation is performed by the key input unit 2). Is done). In this state, the high frequency signal received by the antenna 3 is demodulated into an incoming call signal, so that the slave unit detects the incoming call signal and emits a ringing tone to notify the user that there is an incoming call. After this, as in the above case, the user presses the call button, and the microphone 4 and the speaker 5 enable a normal call. After the call is finished, press the off button to complete the call.

[0007]

That is, the child device is lightweight and small, and it is possible for anyone, not only a child or a child, to freely take it outside and use it in a place where the original user of the child device (eg, parent) cannot see it. Becomes At that time, a child or the like who has a poor sense of money can freely use the call charge without worrying about the call charge, and the original user cannot call attention. In other words, it is too late for the user to notice this for the first time when the call charge is paid.

In addition, if the child device is stolen or taken out by another person against the original intention of the user, an unexpected call charge may be charged later.

The present invention solves the above problems, and in case the person who has a poor sense of money (for example, a child) or another person takes out the child machine against the intention of the original user, the calling destination is The purpose of the present invention is to provide a cordless handset that can be used only in a specific place such as a home where the original user is. Another object of the present invention is to provide a cordless handset configured so that only an incoming call-dedicated unit can be separated from a cordless handset so that a person who has a poor sense of money (for example, a child) can use it as an incoming call-dedicated device.

[0011]

In order to achieve the above object, the present invention is directed to a first key input unit and a second key input unit whose call conditions are limited separately from the first key input unit. And the first key input unit and the second key input unit are selected so that the slave unit of the wireless telephone device can be mounted on the main unit of the slave unit.

According to the present invention, even if another person carries out and uses the slave unit against the original intention of the user,
The call is restricted, and inconveniences such as unexpected call charges are eliminated.
