For example, when the handset number of the other party is dialed by pressing the key 55 after an off-hook operation in the handset 401, these operations are detected by the control circuit 53, and the operation signals are sent to the modem 52 and the wireless unit 5.
1 and the antenna 50 to the base unit 80. On the other hand, when the control circuit 17 in the base unit 80 receives these operation signals via the antenna 24, mixing 23, wireless unit 212, and modem 182,
Modem 181, wireless unit 211, mixing 2
3 and the other party's handset, for example, handset 4 via the antenna 24.
Send a call signal to 02. When the control circuit 53 in the handset 402 receives this call signal via the antenna 50, wireless unit 51, and modem 52, it causes the buzzer 56 to sound. When an off-hook operation is performed in response to this call, this operation signal is detected and transmitted to the base unit 80, and as a result, the crosspoint IC 10 in the base unit 80 is controlled and an exchange connection is established. An extension call is made between handset 401 and handset 402 through crosspoint IC 10, wireless units 211, 212, and the like.

[0009] When an incoming external call arrives on the external lines L and L2 during such an internal call state, the control circuit 17 detects the incoming signal via the photocouplers 21 and 22 and drives the warning sound generating circuit 30. Handset 401 is currently on an extension call,
402, a warning sound is mixed with the audio signal during the call and sent for a predetermined period of time. Thereafter, the voice detection circuit 27 detects the presence or absence of voice signals from the handsets 401 and 402 during an extension call, and when a break in conversation is detected, the crosspoint IC
10 to disconnect the extension communication path, and also control the modem 181 to connect handsets 401 and 402 via the wireless unit 211, mixing 23 and antenna 24.
401 and 4 by transmitting emergency information indicating an incoming external call to handset 401 and 4.
This is displayed on the display 54 and LED section 66 of 02, and the buzzer 56 is sounded. After the control circuit 17 finishes transmitting the control information to the handsets 401 and 402, it controls the crosspoint IC 10 again to close the extension communication path and restart the extension communication between the handsets 401 and 402.

Next, FIG. 5 shows a timing chart of this cordless telephone device, in which (a) shows the voice signals received by the handsets 401 and 402 during an extension call, and (b) shows the voice signals received by the voice detection circuit 27. The timings of the detection output signal, (c) the modem output signal, and (d) the warning sound output signal are shown. That is, in FIG. 5, slave units 401 and 402
indicates the timing when an incoming external call is detected during an internal call. In this case, as described above, after the voice signal of the handset is mixed with a warning sound of "beep beep" and sent, the time t1, t2 If, for example, no output of reception detection is detected due to a break in the conversation between handsets, the extension communication path is disconnected at time t2, and emergency information indicating an incoming external call is sent to each handset using a modem signal. However, when the transmission of control information ends at time t3,
The extension communication path is reconnected to restart the extension communication.

Next, FIG. 4 is a flowchart illustrating the detailed operation of the cordless telephone device of the present invention. In addition,
This flowchart explains the operation of the control circuit 17 within the base unit 80. As mentioned above, for example, handset 4
01 makes an extension call to the handset 402, and the handset 40
2 responds by performing an off-hook operation, handset 40
An extension call is made between the handset 402 and the handset 402 via the crosspoint IC, wireless units 211, 212, etc. (step 100). Next, in step 101,
Determine whether an external call has arrived. When an external call arrives and the determination is "Y" in step 101, the warning sound generation circuit 30 is driven to generate a warning sound of "beep", and this sound is transmitted to the crosspoint IC 10, the wireless unit 22,
Handsets 401 and 4 are in extension call via 1 and 212.
02 and sends it out mixed with the call voice of 02 (step 102
). As a result, the caller who is using the handset 401, 402 to make an extension call hears the warning sound and becomes aware that some information is about to be transmitted, resulting in a momentary interruption in the conversation. In step 103, it is determined whether the received voice of the handset is interrupted continuously for 0.3 seconds based on the presence or absence of the detection output of the voice detection circuit 27. If this is detected, in step 105, the received voice of the handset is interrupted, that is, the voice of the handset is interrupted continuously for 0.3 seconds. In order to instantly disconnect the internal telephone call so that it does not become unnatural, the crosspoint IC 10 is controlled to disconnect the internal telephone line, and in step 106 the modem 181 is controlled to indicate an incoming external call. Emergency information (outside line incoming signal) is sent to the wireless unit 211, mixing 23 and antenna 2.
4 to the handsets 401 and 402, and when the transmission of this information is completed, in step 107, the call is recovered, that is, the crosspoint IC 10 is controlled to reconnect the extension communication path, and the communication between the handsets 401 and 402 is completed. Resume internal calls.

[0012] Furthermore, if the receiving voice of the handset is not interrupted for 0.3 seconds continuously, and therefore the determination in step 103 is "N", the process moves to step 104, and the process is started after the warning sound is sent. It is determined whether or not 7 seconds have elapsed on the timer, and if this is "N", the process returns to step 103, but if 7 seconds have elapsed after the warning sound is sent and it is determined to be "Y" in step 104, then step 105 After the call is disconnected in step 106, an outside line incoming signal is transmitted to the slave units 401 and 402. The control circuit 53 in the slave units 401 and 402 receives the outside line incoming signal from the base unit 80 via the antenna 50, wireless unit 51, and modem 52.
For example, "Gaisenchaksin" is displayed for several seconds on the display 54, which is constituted by an LCD or the like. Thereafter, the display disappears, but the extension caller who is talking through the handset 401, 402 knows that an incoming outside call has arrived, and as a result, can stop the extension call and respond to the incoming outside call.

[0013] In this embodiment, an example of a device accommodating two handsets has been described, but the present invention can also be applied to a device housing three or more handsets. Further, in this embodiment, an example in which an outside call arrives during an internal call has been described, but the present invention is not limited to this. That is, the present invention can be used, for example, when an alarm signal arrives from various alarm sensors while handsets 401 and 402 are on an internal call, when an incoming signal arrives from another outside line during an outside call, and during an outside call or This can be applied to a call from a cordless speakerphone housed as a door intercom slave during an internal call.

[0014]

As explained above, the cordless telephone device of the present invention, when a control signal is detected, mixes and transmits the warning sound of emergency information with the call voice of the handset, and also Since the emergency information is transmitted when an interruption is detected, the emergency information can be transmitted to the handset during the call without impairing the natural conversation. Furthermore, since the display is made in accordance with the emergency information, there is an effect that the transmitted emergency information can be more clearly identified.
