6A) and (26B), and a detection output is supplied from the collector to the control circuit (19).

Next, the operation of the present invention having the above configuration will be described.

First, in a standby state in which no call is made, the slave unit (2) detects whether or not the receiving circuit (14) is intermittently driven and there is no transmission signal from the master unit (1). When there is an incoming call from the telephone line (L), a signal for instructing the incoming call is transmitted from the master unit (1) to the slave unit (2), so that the control circuit (19) of the slave unit (2) that has detected the signal is detected. Drives the buzzer (22) to notify the person near the slave (2) of the incoming call.

When a person who notices the incoming call operates the telephone key of the keyboard (21) of the handset (2) and answers, the transmission circuit (17) of the handset (2) is activated, and the wireless circuit between the parent and child is connected. With the transmission of the response signal from the slave unit (2), the control circuit (8) of the master unit (1) controls the line connection circuit (4) to close the telephone line (L).
The handset (2) can communicate with the caller via the base unit (1).

When the call is ended and the end key of the keyboard (21) is operated, an end signal is transmitted to the base unit (1), and the control circuit (8) of the base unit (1) that has detected the signal transmits the telephone. Release the line (L) and return to the standby state.

On the other hand, when a call is transmitted from the slave unit (2) in the standby state, the control circuit (19) which detects the key signal is operated by operating the talk key of the keyboard (21).
Since the transmission signal is transmitted to the base unit (1), the control circuit (8) of the base unit (1) that has detected the signal closes the telephone line (L) and connects to the exchange of the telephone office. Then, when a dial tone is generated from the exchange, it is transmitted from the base unit (1) to the handset (2) and is received by the handset (2).
When the dial tone is confirmed, when the dial number is input from the numeric keypad, the control circuit (19) generates a dial number signal and transmits it to the master unit (1). As a result, the control circuit (8) of the master unit (1) drives the dial signal generation circuit (11) based on the received dial number signal, and dials the telephone line (L) via the line connection circuit (4). I do. If the other party answers the dial call, the person of the child device (2) can make a call via the parent device (1) in the same manner as described above. Thus, if it is within the communicable range, the handset (2) can be moved to an arbitrary position to make a call.

When not in use, the charging terminals (26A) and (26B) of the child device (2) are connected to the charging terminals (13A) and (13B) of the parent device (1), so that the child device (2) Is charged to the secondary battery (25).

Next, a description will be given of the operation of making the parent device (1) function as an answering machine when going out and answering.

When going out, the keyboard (1) of the parent device (1)
When the answering mode is set by the key operation of 0), when there is an incoming call, the control circuit (8) that detects this incoming call controls the recording device (6) and records the message of the caller.
At the end of the recording of the first message, the control circuit (8) transmits a signal indicating that the message has been recorded to the slave unit (2). On the other hand, the slave unit (2) detects the key input from the keyboard (21) and the reception of the control signal from the master unit (1) in steps (S1) and (S6) shown in FIG. The control circuit (19) that has detected the reception of the control signal in step (S6) proceeds to step (S7) and determines whether or not the signal indicates that the message has been recorded. Since it is a signal indicating that the message has just been recorded, the flow advances to step (S8) to set a flag configured in the control circuit (19). Subsequently, by checking the collector output of the transistor (28), it is detected whether or not the battery (25) of the slave unit (2) is being charged. During charging, the charging terminal (26A) (26
B) is supplied with the charging voltage, and the transistor (2)
When the L-level signal is supplied from the collector to the control circuit (19) by the conduction of 8), the control circuit (19) determines that charging is in progress and proceeds to step (S10) to turn on the transistor (24). The light emitting diode (23) is turned on to indicate that the message has been recorded. However, when the battery is not being charged, the light emitting diode (23) is kept turned on despite the absence of the battery (2) of the child device (2).
Since the step 5) is wasted, only the flag is set and the light emitting diode (23) is not turned on. Each time there is an incoming call during absence, a message is recorded on the recording device (6) of the master unit (1).

Then, when returning home, when checking whether or not a message has been recorded, the slave unit (2) is connected to the master unit (1).
If the light emitting diode (23) is lit, it is possible to go to the parent device (1) and check the display status of the light emitting diode (23) of the child device (2). You can easily see that the message was recorded. On the other hand, when the slave unit (2) is not charging, the user goes to the place where the slave unit (2) is located and operates the confirmation key of the keyboard (21). The circuit (19) proceeds to step (S2) to determine whether or not the key is a confirmation key.
Proceeding to 3), it is determined whether the flag is set. Now that the flag is set, the next step (S
Proceed to 4) to turn on the light emitting diode (23) to indicate that the message is being recorded.

In this way, it is possible to easily determine the presence or absence of the recording of a message, and to reproduce the recorded message by operating the keyboard (10) of the master unit (1). By setting (6) to the playback mode, you can listen to the sound using the speaker (7),
By setting the playback mode with the keyboard (21) of the slave unit (2), the played message is transmitted from the master unit (1) to the slave unit (2), and the receiving speaker (16) of the slave unit (2) is used. ) Can be heard.

If the master unit (1) is provided with a pointing device which is turned on when a message is recorded, it becomes easier to confirm.

[0024]

As described above, the present invention is constructed as described above, so that it is possible to confirm whether or not a message has been recorded in the slave unit, and to indicate the instruction means even if the message has been recorded unless the battery is being charged. Is not driven, so that consumption of the battery of the slave unit can be prevented.
