Next, FIG. 5 shows a timing chart of this cordless telephone system. In FIG. 5, (a) is a voice signal received by the slave units 40 ₁ and 40 ₂ during an extension call, and (b) is a voice detection circuit 27. Shows the timing of the reception detection output signal, (c) shows the timing of the modem output signal, and (d) shows the timing of the notice sound output signal. That is, FIG. 5 shows the timing when an external line incoming call is detected during an extension line call between the slave units 40 ₁ and 40 ₂ .
In this case, as described above, after the warning sound signal of the handset is mixed with the notice sound "pipi" and transmitted, the time t
_If , for example, no output of reception detection is detected between ₁ and t ₂ due to a break in the conversation between the handset units, the extension communication path is disconnected at time t ₂ and the emergency information indicating an external line incoming to each handset unit. Is transmitted by a modem signal, and when the transmission of the control information is completed at time t ₃ , the extension communication path is reconnected to resume the extension communication.

Next, FIG. 4 is a flow chart for explaining the detailed operation of the cordless telephone device of the present invention. In addition,
This flow chart explains the operation of the control circuit 17 in the base unit 80. As described above, for example, the child device 4
0 ₁ performs extension call to the slave unit 40 _2, if the response to this handset 40 ₂ to off-hook operation, crosspoint IC between the handset 40 ₁ and the slave device 40 _2, the wireless unit 2
An extension call is made via 1 ₁ , 21 _2, etc. (step 100). Subsequently, in step 101, it is determined whether an external line incoming call has arrived. Then, when an outside line arrives, step 10
If it is determined to be "Y" in 1, the warning sound generation circuit 30 is driven to generate a warning sound "Pi-pi", and this sound is being used for extension call through the crosspoint IC 10 and the wireless units 21 ₁ and 21 _2. The call voices of the slave units 40 ₁ and 40 ₂ are mixed and transmitted (step 102). As a result, the child device 40
_For callers who are using ₁ and 40 ₂ for extension calls,
Upon hearing the warning sound, he notices that some information will be transmitted from now on, thus causing a momentary break in the conversation. In step 103, it is determined whether the received voice of the handset is disconnected for 0.3 seconds continuously based on the presence / absence of the detection output of the voice detection circuit 27. In order to momentarily disconnect the call so that the extension call of the machine does not become unnatural, the crosspoint IC 10 is controlled to disconnect the extension communication path, and the modem 18 ₁ is controlled in step 106 to accept the outside call. The emergency information (external line incoming signal) shown is transmitted to the slaves 40 ₁ and 40 ₂ via the wireless unit 21 ₁ , the mixing 23 and the antenna 24, and when the transmission of this information is completed, step 107
Then, the reception is restored, that is, the crosspoint IC 10 is controlled to reconnect the extension communication path, and the extension communication between the slaves 40 ₁ and 40 ₂ is restarted.

If the received voice of the handset is not interrupted for 0.3 seconds continuously, and if "N" is determined in step 103, the process proceeds to step 104, and is started after sending the warning sound. It is determined whether or not the timer has passed 7 seconds, and if it is "N", the process returns to step 103. However, if 7 seconds have passed after the advance notice sound was sent and "Y" is determined in step 104, step 105 is performed. After the process shifts to the step of disconnecting the call, the external line incoming signal is transmitted to the slave units 40 ₁ and 40 ₂ in step 106. Then, the control circuit 53 in each of the slave units 40 ₁ and 40 ₂ which receives the external line incoming signal from the master unit 80 via the antenna 50, the wireless unit 51, and the modem 52 is, for example, L
"Geisen Chukshin" is displayed on the display 54 composed of a CD or the like for several seconds. After that, the display is erased,
An extension caller who is in a call via the slaves 40 ₁ and 40 ₂ knows the arrival of an outside call, and as a result, can cancel the extension call and respond to the outside call.

In the present embodiment, an example of a device accommodating two cordless handsets has been described, but it is also applicable to a device accommodating three or more cordless handsets. Further, in the present embodiment, an example in which an incoming call from an external line arrives during an internal call has been described, but the present invention is not limited to this. That is, for example, the present invention is directed to a case where an alarm signal arrives from various alarm sensors during an extension call between the slaves 40 ₁ and 40 ₂ , an incoming signal arrives from another outside line during an outside call, and an outside call. It can be applied to the case where a call is made from a cordless speakerphone housed as an intercom slave during middle or extension calls.

[0014]

As described above, in the cordless telephone device of the present invention, when the control signal is detected, the call sound of the handset is mixed with the notice sound of the emergency information and sent out. Since the emergency information is transmitted when the interruption is detected, there is an effect that the emergency information can be transmitted to the child device during the call without impairing natural conversation. Further, since the display is made according to the emergency information, there is an effect that the transmitted emergency information can be more clearly identified.
