An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a circuit block diagram of a master unit and a slave unit constituting a cordless telephone according to the present invention. In this embodiment, a cordless telephone including one master unit A and n slave units B1 to Bn is shown.

In FIG. 1, a voice unit 12 is bidirectionally connected to a telephone line 1 via a hook switch 11 of a base unit A, and the voice unit 12 has a microphone built in a handset (not shown). The output 17 and the input of a speaker (earpiece) 18 are connected. The audio unit 12
, A transmitting / receiving unit 13 for exchanging audio signals and data signals with the slave units B1... Bn is bidirectionally connected.

The telephone line 1 is connected to an incoming call detector 10 for detecting a call signal.
Are guided to the control unit 15 which controls the operation of the entire master unit A.

The output of the operation input unit 16 having numeric keys and various function keys is led to the control unit 15, and the output of the control unit 15 is led to the audio unit 12. Further, the control unit 15, the storage unit 14 for storing the operation restriction information, and the transmission / reception unit 13 are each connected bidirectionally, and the transmission / reception unit 13 is connected to the antenna 19.

On the other hand, a transmitting / receiving unit 22 for transmitting and receiving a voice signal and a data signal to / from the master unit A is bidirectionally connected to the antenna 29 of the slave unit B1. The audio unit 21 to which the output of the microphone 27 built in the handset not connected and the input of the speaker (earpiece) 28 are connected bidirectionally.

An output of an operation input unit 24 provided with various function keys such as a calling operation and an extension calling operation is led to a control unit 23 for controlling the operation of the whole handset B1. Is guided to the audio unit 21. Further, the control unit 23 has a configuration in which the transmission / reception unit 22 is bidirectionally connected and a buzzer 26 for notifying operation restriction and the like is connected. Although not shown, the other slave units B2... Bn have the same configuration as the slave unit B1.

Next, in the cordless telephone having the above configuration, a call operation (dial transmission operation) from the slave unit B1 whose operation is restricted will be described with reference to a flowchart shown in FIG.

First, the user of the cordless telephone operates the operation input unit 16 of the base unit A to cause the storage unit 14 to store information indicating the calling restriction of the handset B1. As a result, the storage unit 14 stores the information indicating the call restriction and the ID code of the slave unit B1 that performs the restriction. Reason
In addition, the storage unit 14 stores the operation of the other slave units B2.
Naturally, the contents of the work regulation can also be stored. For example, child
The device B2 is information for restricting all operations other than the incoming call,
3 is information that restricts only calls to the specified station code
It is.

In this state, when a key operation of a call request is performed from the operation input unit 24 in the slave unit B1, an operation signal indicating the call request is transmitted to the control unit 23 and the transmission / reception unit 2
2. The signal is received by the transmission / reception unit 13 of the master unit A using the control channel through the path of the antennas 29 and 19,
5 (step S1). This operation signal includes:
In addition to the call request, an ID code for identifying the slave unit B1 on the master unit A side is included.

The control unit 15 determines from the received operation signal whether the signal is an incoming call from an outside line or an operation signal from a child device, and if the operation signal is from a child device, the operation signal is included in the operation signal. Identify the included ID code (step S
2, S3). After that, the control unit 15 reads the operation regulation information stored in the storage unit 14 and compares the ID code given to the read operation regulation information with the ID code given from the transmission / reception unit 22. Perform (Step S4). In this case, since both ID codes match, master device A shifts to the operation restriction operation next.

That is, master unit A outputs a signal indicating that operation is restricted (hereinafter, referred to as an operation restriction state signal) to slave unit B1 without capturing telephone line 1 (step S5). . That is, the operation restriction state signal is transmitted to the slave unit B via the transmission / reception unit 13 and the antennas 19 and 29.
1 and transmitted to the control unit 23. When the control unit 23 recognizes that the handset B1 is in the call control state based on the operation control state signal, the control unit 23 drives the speaker 28 via the buzzer 26 and the audio unit 21 to use the handset B1. Informs the caller that the call is being restricted. When the user of the slave unit B1 that has heard the buzzer sound or the like on-hooks the slave unit B1, the slave unit B1 is turned on.
1 returns to the original standby state.

On the other hand, if the handset B1 is not in the call restriction state in step S4, the master A
The operation proceeds to step 6, and then the normal line capture operation is performed.
The connection between the corresponding slave unit and the telephone line 1 is performed (step S
6 to S10).

As described above, when the operation restriction is set, the base unit A performs the subsequent operation restriction operation without capturing the outside line, so that when the calling signal is transmitted through the telephone line 1 during this operation. However, the incoming call detection unit 10 can detect this calling signal. In addition, since the contents of the operation restriction of the cordless telephone can be confirmed from any of the slave units, a reliable operation of the cordless telephone can be ensured.

On the other hand, when a call signal is transmitted through the telephone line 1, the call signal is detected by the incoming call detection section 10, and the incoming call detection signal is given to the control section 15. When the control unit 15 confirms that the incoming call is an outside line based on the incoming call detection signal (step S2), the control unit 15 drives an internal speaker (not shown) to output a ringing tone, Slave unit B1
Transmit a call signal to Bn (step S21). When an arbitrary slave unit (for example, B1) answers this call (step S22), both the slave unit B1 and the master unit A switch from the control channel to the communication channel (step S221). An external line capture signal is transmitted from the device B1 to the master device A (step S22).
2). Upon receiving this outside line capture signal (step S223), master unit A1 confirms completion of incoming call reception preparation by slave unit B1 and transmits an outside line capture permission signal for connecting slave unit B1 to telephone line 1. 13. Transmission is made to the slave unit B1 via the antenna 19 (step S9). Thereafter, the control unit 15 sets the hook switch 11 to the off-hook state and captures an outside line (step S10), whereby the slave unit B1
Can answer incoming calls.

In the above embodiment, only the operation restriction regarding the call restriction is described.
As described above, the slave unit B2 controls the operation of all operations except the incoming call.
And the handset B3 contains information that regulates only transmission to a predetermined station number.
If such operation restriction information is provided and the absence setting function is provided, for example,
And the information that regulates the resetting of the answering machine to zero
If such operation regulation information is stored in the storage unit 14,
It is possible to perform various operations regulations corresponding to each child machine for each child machine.

In the above embodiment, the buzzer is used as a means for notifying the operation restriction, but a light emitting device or a display device can be used as another configuration.

[0026]

According to the cordless telephone of the present invention, the operation regulation by a plurality of slave units can be set on the master unit side for each slave unit. Do
Can be. For example, if you set the call regulation in any of the child machine, it is never such as forced to pay hardly recognized for billing the payer due to unnecessary call from the child machine. Also, if the system is equipped with the absence setting function, different operations such as the absence setting cancellation regulation and the absence recording zero reset regulation
Since the restrictions can be set on the different slave units on the master unit side, it is possible to prevent occurrence of a situation in which the answering machine is unintentionally released from the corresponding slave unit or the absence recording is reset. Further, in response to a call request from a slave unit whose operation is restricted, master unit A performs a subsequent operation restriction operation without capturing an outside line. Since the call signal can be detected, various effects such as ensuring smooth communication can be obtained.
