An outside call from the telephone line 4 is guided to the telephone section 31 which connects to the telephone line 4, detects an incoming call from the other party's terminal, dials out, etc.
It is connected to one terminal a of 6. Changeover switch 36
The output of the recording/reproducing section 34 is connected to the other terminal C, and the common terminal C is dedicated to the transmitting/receiving section 32. The output of the transmitting/receiving section 32 is guided to an antenna 35 that transmits and receives signals to and from the handset 1.2. Further, the recording/reproducing section 34 and the transmitting/receiving section 32 are each connected to the control section 33 so that data can be transferred in both directions.

On the other hand, in the handset 1, an antenna 15 for transmitting and receiving signals to and from the base unit 3 is guided to a transmitting/receiving section 10, and this transmitting/receiving section 10 receives the output of a control section 11 that controls the operation of the transmitting/receiving section 10. being guided. The control unit 11 also includes a transfer switch 14 whose one terminal is connected to ground.
The other terminal of the hook switch 16 is connected, and the other terminal of the hook switch 16 whose one terminal is connected to ground is also connected. Further, the audio input from the microphone 12 is guided to the transmitting/receiving section 10, and the output of the transmitting/receiving section 10 is guided to the speaker 13. Note that the handset 2 also has the same configuration as the handset 1 described above.

Next, the operation of the cordless telephone with the above configuration will be explained.

First, the operation during a normal outside line call will be explained.

During an outside line call, the selector switch 36 of the base unit 3 is connected to the terminal a side, and the slave unit l is connected to the base unit 3 via both antennas 15°35.

That is, the audio signal input from the microphone 12 is transmitted from the antenna 15 via the transmitting/receiving section 10, is received by the transmitting/receiving section 32 via the antenna 35 of the main unit 3, and is sent to the terminal a of the changeover switch 36 and the telephone section. 31 to the telephone line 4. Also, the audio signal from the telephone line 4 is input to the telephone section 31, transmitted from the antenna 35 via the terminal a of the changeover switch 36 and the transmitting/receiving section 32, and then transmitted to the transmitting/receiving section 10 via the antenna 15 of the handset 1. The signal is received and output from the speaker 13 as an audio signal.

In addition to a transfer switch 14 and a hook switch 16, the control unit 11 of the handset 1 is equipped with switches that a normal telephone has, such as a dial switch and a hold switch (not shown). When an operation is detected, information (digital data, etc.) corresponding to the function of the operated switch is transmitted to the base unit 3 via the transmitting/receiving section 10.
Telephone operations are realized by transmitting information to the base unit 3 and receiving and receiving information from the base unit 3.

In addition, the control unit 33 of the base unit 3 receives and receives information from the slave unit l, controls the transmitting/receiving unit 32 and the telephone unit 31 according to the information G, and detects an incoming call from the telephone unit 31 (not shown). After receiving the information, it performs control such as calling the handset 1. Such operation is similar to a conventional cordless telephone. In addition, the control unit 33 receives the information 11! from the handset 1!
&Thus, the recording/playback section 34 starts the recording operation and the playback operation.

The recording/playback section 34 is composed of a normal tape recorder, a recording/playback IC, etc., and records and plays back the audio signal input from the terminal of the changeover switch 36 according to instructions from the control section 33. An operation is performed in which the audio signal is output to the terminal of the changeover switch 36.

Note that the connection and communication between the handset 2 and the base unit 3 are also the same as in the case of the handset 1 described above, so the explanation will be omitted here.

Next, refer to the flowchart showing the transfer procedure in Figure 2 for the transfer operation when transferring a call from the above-mentioned state where a call is being made between handset 1 and base unit 3 to slave m2. and explain.

When the transfer switch 14 of the handset 1 is pressed, the control unit 11
detects this, enters transfer mode, and sends out an instruction signal to start recording (step ■). This recording instruction signal is sent to the control section 33 via the transmitting/receiving section 10, the antenna 15.degree. 35, and the transmitting/receiving section 32 (steps (2) and (2)). Upon receiving this recording instruction signal, the control unit 33 puts the telephone line on hold and switches the changeover switch 36 from terminal a to terminal A while the telephone line is captured (step 2).
. Further, the control unit 33 starts the recording/playback unit 34 and puts the recording/playback unit 34 into a recordable state (step ■).
.

In this state, the user of handset 1 inputs the message he wants to convey through microphone 12, and the message is sent to transmitting/receiving section 10. Recording is performed through the terminals of the antennas 15, 35, the transmitter/receiver section 32, and the selector switch 36.
It is recorded on the playback section 34. After that, by on-hooking the handset 1 and opening the hook switch 16, the controller 11
After issuing a transfer instruction, the device enters standby mode (steps ■, ■).

This transfer instruction signal is sent to the transmitting/receiving section 10 and the antenna 15.3.
5, and is sent to the control unit 33 via the transmitting/receiving unit 32. Upon receiving this transfer instruction signal, the control unit 33 sends a recording stop signal to the recording/playback unit 34, stops the recording operation of the recording/playback unit 34, and ends the call with the handset 1 (step ■, ■).

On the other hand, the control unit 33 includes the transmitting/receiving unit 32 and the antenna 35°25.
calls the handset 2 via the handset 2, and instructs the control unit 21 in the handset 2 to receive the call. Handset 2 receives this, changes from standby mode to incoming call mode, and outputs the ringer tone of handset 2 (
step [phase], ■).

When the user of the handset 2 picks up the phone, the hook switch 26 closes, and the control unit 21 detects this off-hook state and sends an instruction signal to the base unit 1 indicating that the call is possible. Send (step @). Since the control unit 33 of the base unit 1 remembers that the transfer is between the slave units 1 and 2 based on the transfer instruction signal from the slave unit 1,
Upon receiving the instruction signal from the handset 2, it instructs the recording/playback section 34 to play. As a result, the message from the handset 1 recorded in the recording/playback section 34 is transmitted from the speaker 23 via the terminal b of the changeover switch 36, the transmitting/receiving section 32, the antenna 35° 25, and the transmitting/receiving section 20. The message will be conveyed to the user of machine 2 (step 0.
0). When the transmission of this message is completed, the control unit 33 of the base unit 1 detects this and switches the connection of the changeover switch 36 from the terminal to the terminal a side, thereby connecting the telephone line 4 and the slave unit 2. perform (step [phase], @)
.

As a result, the handset 2 enters into a conversation state with the other party via the telephone line 4.

In addition, in the above description of the transfer operation, the telephone line 4 is connected to the handset l.
We have explained the case where data is transferred from to handset 2, but when handset 2
When transferring from to handset 1, it can be done in exactly the same way.

In addition, in the above description of the transfer operation, the transfer switch 14
．． Although the recording/playback unit 34 starts recording by pressing the button 24, it is also possible to provide a separate switch for recording. Furthermore, it is possible to directly connect the recording/playback section 34 to the telephone section 31 to add an answering machine function.

(Effects of the Invention) As described above, according to the cordless telephone of the present invention, messages can be transmitted when transferring between slave units, so the transfer operation can be performed more smoothly. In addition, in order to perform this transfer operation, there is no need to have two transmitters/receivers in the child device, one for the parent device and one for the child device, so the device can be made smaller and economical. be.
