FIG. 2 is a flowchart showing the main operations of the main body control means 4 in the above embodiment, and FIG. 3 is a flowchart showing the main operations of the portable control means 7 in the above embodiment.

The operation of the embodiment shown in FIG. 1 will be explained based on these flowcharts. First, in the mobile unit, the mobile unit control means 7 checks in steps 32 and 33 whether the mobile unit radio wave transmitting/receiving unit 8 has received an automatic incoming call command or a ringing command from the main body, and in step 35
It is checked whether the call input means 6 has been operated. Then, in the main body, the main body control means 4 checks in step 15 whether the central office line connecting means 1 has detected a calling signal from the central office line, and in step 16 the radio wave transmitting/receiving means 3 receives a call from the mobile unit. Checking whether command has been received.

Now, to explain the normal call starting operation, when the operator operates the call switch means 6 (step 35), the mobile part control means 7 sends a call command to the main body part via the mobile part radio wave transmitting/receiving means 8 in step 47. At the same time as the transmission, the communication system is linked in step 48, and the transmitting mute means 12 is released in step 46 to enter a communication state. At this time, when the main body control means 4 receives the call command via the main body radio wave transmitting/receiving means 3 (step 16), step 1
At step 7, the office line is connected to the office line connecting means 1, and at step 18, the communication system is linked, and a communication state is established, allowing the microphone 11 of the portable unit and the receiver 10 to communicate with the office line.

Next, automatic response operation will be explained. When a calling signal is sent from the office line (step 15), the office line connecting means 1 of the main body detects this, and the control means 4 uses the office line calling signal detection information from the office line connecting means 1 to perform step 19. Then, a ringing command is transmitted to the mobile unit via the radio wave transmitting/receiving means 3 of the main body. On the other hand, when the mobile unit control means 7 receives the ringing command via the mobile unit radio wave transmitting/receiving means 8, it determines this in step 33, and causes the ringing means to ring in step 34 while the ringing command continues to be sent. When the main unit control means 4 determines in step 20 that the calling signal has continued for a certain period of time, it transmits an automatic response command to the mobile unit via the main unit radio wave transmitting/receiving means 3 in step 21, and in step 22 it transmits an automatic response command to the mobile unit. The line connecting means 1 is connected to the central office line, and in step 23, the response sending means 2 is activated to send a response to the line. At this time, when the mobile unit control means 7 receives the automatic response command via the mobile unit radio wave transmitting/receiving means 8, it determines this in step 32 and moves on to monitoring in steps 36 and 37. Here, when the call switch 6 of the mobile unit is operated, the mobile unit control means 7 detects this in step 36,
In step 38, a monitor command is sent to the main unit via the mobile radio wave transmitting/receiving means 8, in step 39 the muting means 12 is set, and in step 40 the communication system is linked.

The control means 4 of the main body section is the radio wave transmitting/receiving means 3 of the main body section.
When a monitor command is received via the , this is detected in step 28 and the communication system is linked in step 30 . This allows the voice of the central office line to be monitored from the receiver 10 of the mobile unit while continuing the automatic response operation on the main unit.

In this state, when the hooking switch 13 of the mobile unit is input, the mobile unit control means 7 detects this in step 44, and in step 45 transmits a call command to the main unit via the mobile unit radio wave transmitting/receiving means 8. Press 46 to cancel mute.

This hooking switch 13 is generally used when switching the other party in a call waiting service or the like. Use this hooking switch to switch from monitor state to call state. Then, when the main body control means 4 receives the call command via the main body radio wave transmitting/receiving means 3, it detects this in step 29, and in step 31
Stops the response sending means 2, cancels the automatic response operation, and sends a call letter f between the central office line, the microphone 11 of the mobile unit, and the receiver 12.
i (step 49). When the transmission of the automatic response to the line is completed in the main unit (step 24), the central office line connecting means 1 is made to open the central office line (step 25), and the communication link is released (step 26). Furthermore, an automatic response end command is sent (step 27), and the process returns to the initial state (step 15). When the mobile unit receives the automatic response end command (step 43), it cancels the communication link (step 41), then cancels the mute (step 42), and returns to the initial state (step 32). Note that if the call switch is operated (step 50) instead of the hooking switch input (step 44), this is the same as forcibly terminating the automatic response (steps 43, 4X).

In this way, according to the above embodiment, when the same operation as that for starting a call is performed on the mobile part during the automatic answering operation of the main body part, the mobile part enters the central office line monitoring state. This can prevent unnecessary call interruptions.

Furthermore, by using the hooking switch that is used when switching the caller in call waiting services, etc. as a changeover switch from the monitor state to the call mode, it is possible to immediately switch to a call after confirming the caller without any operational discomfort. .

In the above embodiment, the mute means is installed in the portable part, but the same effect can be obtained even if it is installed in the transmission system of the main body part. Further, in the above embodiment, the response sending means only sends a response, but it may also include means for recording the caller's business. In this case, the effect of making it easier to confirm the caller can be obtained.

In the above embodiment, a hooking switch is used as a switching means for switching from a monitor state to a call state.
In other embodiments, one call switch means can also have the function of this changeover switch. That is, when one call switch is pressed, the monitor state may continue as long as the switch is kept pressed, and the switch may switch to the call state when the finger is released from the pressed state.

Effects of the Invention As is clear from the above-mentioned embodiments, the present invention is configured so that when the main unit is in automatic answering operation and the same operation as starting a normal call is performed on the mobile unit, the main unit enters the central office line monitoring state,
Therefore, since it is cordless, even if you operate it without knowing the operation of the main body part, there is an advantage that you can prevent unexpected call interruptions during automatic answering operation. Furthermore, it has the effect that after confirming the caller, it is possible to make a call using another operation.
