The slave unit is used movably, and can be used in a state set in the master unit. Here, the master unit and the slave unit are respectively paired, and identification information is set and registered in advance for each pair. However, if another child device that does not correspond to this is set in the parent device, and there is an incoming call to this other child device, whether the original child device corresponding to the parent device has received an incoming call, Is confused because it is not possible to judge whether there is an incoming call to the child device.

Therefore, when the slave unit is set in the master unit,
If the identification information of the slave unit and the master unit is different, this is detected by the detecting means, and the setting registration of the identification information of the slave unit is changed, so that when the slave unit is set in the master unit, 2. Description of the Related Art A cordless telephone device has been known in which a handset set in a base unit always calls when an incoming call is received, so that it is possible to recognize who is calling (Japanese Patent Laid-Open No. Hei 4-271645). No.).

FIG. 3 is a block diagram showing an example of the above-mentioned conventional cordless telephone device. In the figure, when the slave 1 is set on the main body of the master 2, the identification information 3 registered in the slave 1 is transmitted to the identification unit 4 of the slave 2 by the identification unit 4 of the master 2.
And identifies whether the child device 1 is a child device registered in the parent device 2 or not. If the handset recognizing unit 4 recognizes that the handset is not registered in the master unit 2, it supplies an identification result signal 6 to the identification information change unit 7, and the identification information change unit 7 sends the identification information to the handset 1. The change signal 8 is output, and the identification information 3 is re-registered so as to be a slave of the master 2.

The output signal to the outside is identification information of the slave unit 14.

Since the base unit 10 is connected to the telephone network 15 and does not usually move, it is installed at an arbitrary position, while the slave unit 14 is set on the base unit 10 or not. It is configured so that a user can carry and receive calls. When the master unit 10 and the slave unit 14 are the original master unit and the slave unit used in combination, the identification numbers of both are the same, but the slave unit 14 is the slave unit connected to another master unit. Sometimes their identification numbers are different.

Next, the operation of this embodiment will be described.
When the slave unit 14 is set on the master unit 10, the connection terminal 3 of the master unit
3 and 34 are connected to the connection terminals 47 and 48 of the slave unit 14, and at the same time, the external connection terminals 35 and 49 are also connected. When the connection terminals 33 and 34 are connected to the connection terminals 47 and 48,
The power supply voltage from the power supply circuit 30 is
4 to charge it and control devices 25 and 3
7 are bidirectionally connected via an interface (I / F) circuit 32, connection terminals 33 and 47, and an interface (I / F) circuit 45. As a result, the control device 37 in the child device 14 determines that the child device 14 has been connected to the master device 10, and
The storage identification information in the terminal identification information memory 43 is read out and output to the external connection terminal 49.

The identification information of the slave unit 14 is stored in an external connection terminal 49.
Is supplied to the control device 25 in a wired manner via the external connection terminal 35 of the master device 10 connected to the master device 10. The control device 25 determines that the slave unit 14 has been set by connection with the control device 37, and takes in the identification information of the slave unit input from the external input terminal 35, and at the same time, from the terminal identification information memory 31
After reading the identification information, the identification information is compared and collated.

The control unit 25 constitutes the slave unit recognizing unit 12, and when the identification information of the master unit 10 and the above-mentioned external input slave unit identification information match, the slave unit 14
The identification result transmitting unit 13 is not driven by judging that the slave unit should be originally set to the slave unit. However, when the two pieces of identification information do not match, the slave unit 14 should be set to the master unit 10 originally. It is determined that it is not a slave unit, and the identification result signal is supplied to the identification result transmitting unit 13, whereby the fact that the identification information does not match is transmitted to the outside by means of a buzzer sound or a light emitting diode display.

By transmitting the identification information mismatch by the identification result transmitting unit 13, the user of the slave unit 14 can determine that the slave unit is not the slave unit to be set in the master unit 10, and as a result, the master unit 1
By canceling the setting to 0, it is possible to prevent an incorrect combination of the master unit and the slave unit. Therefore, the one-touch dial and the abbreviated dial registered in the abbreviated dial register 46 can be reliably used for each slave unit.

Also, since the identification information of the child device 14 is not re-registered, the original parent device that has been using the child device 14 cannot identify the child device 14, and It is also possible to prevent a phenomenon in which the child device 14 cannot be returned to the original parent device.

[0025]

As described above, according to the present invention,
When the slave unit is set in the master unit, the identification information set in the slave unit is transmitted to the master unit 10 by wire, and the identification information of the self unit in which the master unit is registered and the identification information of the entered slave unit Since the identification / contradiction is determined, and in the case of a disagreement, the fact is transmitted to the outside by the identification result transmitting unit, the user of the child device can determine that it is not the child device to be set in the parent device. By canceling the setting to the result master unit,
It is possible to prevent erroneous combination of the master unit and the slave unit, and it is possible to reliably use the one-touch dial and the speed dial registered in the slave unit.

Further, since the identification information of the child device is not re-registered, the original parent device that has used the child device until now cannot identify the child device, and the child device used by itself is not used. The phenomenon that the child device cannot be returned to the original parent device can also be prevented.
