The audible display 25 and the visual display 27 are configured to display an incoming call.

Next, the operation of the first embodiment will be described. In the initial state, in the master unit shown in FIG. 1A, when there is an incoming call, all the slave unit incoming call display means 9 are activated and the specific slave unit incoming call display means 13 does not operate. Therefore, when there is an incoming call, the incoming call is displayed on all the slaves. That is, in the conventional cordless telephone device shown in FIG. 6, the incoming call display stop switch is not operated and the incoming call display stopping means 52 is not in operation. Here, in the slave unit shown in FIG. 1B, the operation unit 2
When the setting operation by 8 is performed, the microprocessor 29 detects that the setting operation is performed by the signal from the operation unit 28, controls the data transmitting unit 21, and wirelessly operates the transmitting circuit 18 and the antenna 20. The master device is notified of this by transmitting the data signal of. In the parent device shown in FIG. 1A, the microprocessor 14 has a data signal received and demodulated by the antenna 5 and the receiving circuit 4 and taken out by the data receiving means 8, and a setting operation is performed by the first determining means 10. When it is detected that the action has been performed on the machine, the timer 12 is started and the time counting operation is started. When an incoming call is received, the incoming call detection circuit 6 outputs a detection signal to the microprocessor 14,
At this time, when the timer 12 is in the timekeeping operation, the microprocessor 14 activates the specific slave unit arrival display means 13 instead of activating all the slave unit arrival display means 9, and controls the data transmission means 7. A data signal is transmitted to the slave unit, which causes only the slave unit, which has been discriminated and determined by the second determining means 11 to perform the setting operation, to display the incoming call. In the child device receiving the data signal, the microprocessor 29

Display incoming call. That is, the incoming call display is performed on the slave unit on which the setting operation is performed, but the incoming call display is not performed on the other slave units. Then, when a certain period of time has passed since the timer 12 in the master unit was started, the time counting operation was completed, and an end signal was output, the microprocessor 14 received this, and if there was an incoming call, the specific child Since the machine incoming call display means 13 is not activated and all the slave station arrival display means 9 are activated, the state is returned to the state in which the call arrival is displayed in all the slave machines.

As described above, according to the first embodiment,
When there is an incoming call within a certain time after the setting operation is performed on the slave, there is an effect that only the slave that has performed the setting operation can display the incoming call. In addition, when there is an incoming call while the specific handset incoming display means 13 is operating, and the user who performed the setting operation while the handset that performed the setting operation is displaying the incoming call does not respond to the incoming call. However, when the timer 12 finishes the time counting operation after a fixed time from the activation and outputs an end signal, all the slave unit incoming call display means 9 are activated and the incoming call display is started in all the slave units. This has the effect of making it possible to notify the user near the user of the incoming call.

In the first embodiment, the timer 12 of the master unit may be started when the setting operation is performed on the slave unit while the timer 12 is in the timekeeping operation. The timer 12 can also be configured to be restarted when the setting operation is performed again from the child device that first started the setting operation and started the timer 12 during the time counting operation of the timer 12. By doing so, there is an effect that it is possible to extend the time during which the incoming call display is performed only for the slave unit that first performs the setting operation by performing the same setting operation again.

Since the slave unit shown in FIG. 2B has the same configuration as the slave unit shown in FIG. 1B in the first embodiment, its explanation is omitted.

Next, the operation of the second embodiment will be described. A setting operation is performed in an arbitrary slave unit by the same operation as that of the first embodiment, and by any one of the slave units during the time counting operation of the timer 12 started by the determination of the first determining unit 10. When the microprocessor 31 of the parent device controls the network control circuit 1 to perform the call operation through the telephone line, the third determination means 30 outputs the determination result to the microprocessor 31. The microprocessor 31 which has detected this determination result ends the time counting operation of the timer 12. As a result, when the end signal is output from the timer 12, the microprocessor 31 receives the end signal and does not activate the specific child device incoming call display means 13 when an incoming call is received, but all the child device incoming call display means 9 are displayed. Since it is returned to the state of activating, the next time when there is an incoming call, it returns to the state where the incoming signal is made in all the slaves.

As described above, according to the second embodiment,
Even when a setting operation is performed so that the specific handset reception display means 13 is activated at the time of an incoming call, if a call operation is performed through a telephone line by an operation from any of the handset, the setting is automatically released. Therefore, when the call ends and it is no longer necessary to maintain the state in which the setting operation is performed, it is not necessary to bother to perform the release operation by the operation unit 28.

While the timer 12 being activated is operating in a state where the second determination unit 11 identifies and determines the slave unit for which the setting operation has been performed,
When the microprocessor 33 of the parent device controls the network control circuit 1 to perform the call operation through the telephone line by an operation from any one of the child devices, the third determination means 30 determines that the call is being performed. Microprocessor 33
Output to. At the same time, the fourth determination means 32 outputs to the microprocessor 33 the identification determination result of which handset the call operation is performed. The microprocessor 33, which has detected these identification determination results, collates the slave unit, which has been subjected to the setting operation identified and determined by the second determination unit 11, and the slave unit, which has been identified and determined by the fourth determination unit 32. If the two match, the timer 12 ends the time counting operation. That is, the time counting operation of the timer 12 ends only when the handset that has performed the call operation is the handset that has performed the setting operation. As a result, when the end signal is output from the timer 12, the microprocessor 33 receives the end signal, and when there is an incoming call, the specific handset incoming display means 13 is displayed.
Is not started, but the state returns to the state in which all the slave incoming call display means 9 are started.

Therefore, in this case, within a certain time range, there is an effect that it is not necessary to perform the setting operation again until the child device which has performed the setting operation responds to an incoming call.

Both the all-child device incoming call display means 34 and the specific child device incoming call display means 40 are configured to control the incoming call display means 35.

Since the slave unit shown in FIG. 4 (b) has the same structure as the slave unit shown in FIG. 1 (b) in the first embodiment, its explanation is omitted.

Next, the operation of the above fourth embodiment will be described. Even if the timer 12 is not counting time,
When there is an incoming call, the incoming call detection circuit 6 outputs a detection signal to the microprocessor 14. As a result, the microprocessor 14 activates the all-child-unit incoming-call display means 34 and controls the data transmitting means 7 to cause all the child-units to display the incoming-call display and transmit the data signal, but at the same time, all the child-unit incoming-call display The means 34 controls the incoming call display means 35 so that the incoming call can be displayed on the master unit. Further, similar to the operation in the first embodiment described above, the setting operation is performed in any slave unit, so that the incoming call is received while the timer 12 is counting according to the determination result of the first determining unit 10. If there is, the microprocessor 14 causes all the incoming call reception display means 3 to operate.
Instead of 4, the specific handset incoming display means 40 is activated to display the incoming call only in the handset for which the setting operation has been performed. The operation is prohibited so that the incoming call is not displayed on the master unit.

As described above, according to the fourth embodiment, in the cordless telephone apparatus configured to display the incoming call also in the master unit, when an incoming call is received, both the master unit and the slave unit receive the incoming call. This has the effect that the operation of displaying an incoming call similar to that of the first embodiment can be performed.

At the same time, the microprocessor 41 sends the detection signal detected by the personal identification number detection circuit 42 to the slave unit through the data transmission means 7, the transmission circuit 3 and the antenna 5. In the child device receiving this, the detection signal is input to the microprocessor 49, and the microprocessor 49 causes the special incoming call display means 4
8 is controlled to cause the slave unit to display the special incoming call display similar to that in the master unit. In this way, when the special incoming call display means 45 for all the slaves is controlled to display the special incoming call from the master, the special incoming call is displayed on all the slaves and the master. By the way, at this time, when the timer 12 is counting by the setting operation from the slave unit, the microprocessor 41 controls the specific slave unit special incoming call display means 47 and only the slave unit for which the setting operation is performed. Make a special incoming call display. At the same time, the microprocessor 41 sends out the detection signal detected by the personal identification number detection circuit 42 to only the slave unit for which the setting operation has been performed through the data transmission means 7, the transmission circuit 3 and the antenna 5. In the slave unit which received the setting operation, the detection signal is input to the microprocessor 49, and the microprocessor 49 controls the special incoming call display means 48 to display the special incoming call display similar to that in the master unit. Let the child perform it.

As described above, according to the fifth embodiment, in the cordless answering machine, it is possible to display a special incoming call by inputting the personal identification number from the person who made the call. This has the effect of allowing only the slave unit that has performed the setting operation to display the special incoming call.

As is apparent from the above embodiment, the present invention has the following effects in a cordless telephone device.

(1) First determining means for performing a predetermined setting operation for displaying an incoming call in the slave unit and determining whether this setting operation has been performed in the master unit, and in which slave unit this setting is made. Since the second determination means for determining whether or not the operation has been performed and the timer activated by the first determination means are provided, the incoming call display is displayed only on the slave unit that requires the incoming call display until a predetermined time elapses. However, it is possible not to display the incoming call on the other handset.
Therefore, for example, when there is a telephone call addressed to me at a certain time, it is possible to ring only the child device for myself and not ring the child device in the bedroom where the child is sleeping. .. In addition, this function is automatically canceled after a certain period of time, so that it is possible to avoid the situation where the user does not notice the incoming call.

(2) The timer operation time can be extended by performing this setting operation even when the timer operation is in progress.

(3) Since the third judging means for judging that there is a call during the time counting operation of the timer is provided, after that, if there is a call, all the handset units will display the incoming call. It can be returned automatically.

(4) When a call is made during the time counting operation of the timer, since the fourth judging means for judging in which handset the call is made is provided, the setting operation is carried out until a fixed time elapses. It is not necessary to perform the setting operation again in the slave unit that has performed until the call is answered.

(5) Since the master unit also includes all the slave unit incoming call display means and the specific slave unit incoming call display unit, it is possible to collectively display the incoming call display in all the slave units in the master unit.

(6) Since the personal identification number detection circuit, all the slave unit special incoming call display means and the specific slave unit incoming call display means are provided,
Even in the cordless telephone device with the answering machine function, the incoming call display operation similar to the above (1) can be performed.
