The control circuit 12a controls the wireless transmitting circuit 17, the speaker 19, etc. based on the control signal Data from the wireless receiving circuit 11, CD information, and information from the operation section 12a.

Next, the operation of the above embodiment will be explained.

Note that the operations for calling, calling, and receiving calls are the same as those described in the conventional example, so the explanation thereof will be omitted.

First, the case where a response message upon automatic call reception is recorded on the magnetic tape drive mechanism 25 will be described.

When recording from the microphone 24 of the base station 1a, when the user presses the recording button on the operation unit 22a, the control circuit 6a activates the magnetic tape drive mechanism 25.

As a result, the magnetic tape drive mechanism 25 moves the microphone 2
For example, input from 4: ``I'm away from home at the moment.''

Please send a message after the beep. ” is recorded as a response message.

In addition, when recording from the transmitter 15 of the mobile station 2a, when the user presses the recording button on the operation unit 23a, the control circuit 12a transmits the information to the antenna 10 and the wireless line 3 via the wireless transmission circuit 17. It is transmitted to the base station 1a via the base station 1a.

The radio receiving circuit 7 of the base station 1a receives this information and outputs it to the control circuit 6a. The control circuit 6a thereby:
The magnetic tape drive mechanism 25 is driven, and the low frequency amplifier circuit 16, the wireless transmission circuit 17,
A response message input via the antenna 10, radio line 3, antenna 9, and radio receiving circuit 7 is recorded by the magnetic tape drive mechanism 25.

After inputting the above response message, when the stop button on the operating section 22a of the base station 1a or the operating section 23a of the mobile station 2b is pressed, the control circuit 6a of the base station 1a will thereby control the magnetic tape drive mechanism 25. to end recording.

On the other hand, a case will be explained in which a message regarding the caller's business is recorded when the caller is away.

First, when the answering button on the operation unit 22a of the base station 1a is pressed, the control circuit 6a controls the magnetic tape drive mechanism 25.2.
6 and set it to answering mode.

Then, the wireless transmission circuit 8 transmits information that the answering mode has been set via the antenna 9 and the wireless circuit 3. The control circuit 12a of the mobile station 2 transmits this information to the antenna 10.
, received via the wireless receiving circuit 11,
Stop supplying power to.

Further, when the answering button on the operation unit 23a of the mobile station 2a is pressed, the control circuit 12a sets the base station 1a to answering mode, and then stops supplying power to the radio receiving circuit 11.

In this answering mode, when the line detection circuit 4a detects an incoming call signal on the telephone line, the control circuit 6a turns on the hook-and-hitch 20 to capture the telephone line, and the magnetic tape drive mechanism 25 sends out the message ``I am away at the moment.'' After the beep, a response message is sent to the telephone line: Message please.''

Then, the control circuit 6a puts the magnetic tape drive mechanism 26 into a recording-enabled state, and records the business message from the calling party, for example, 5 seconds after sending the response message. When the caller finishes the business message and releases the telephone line, the line detection circuit 4a detects this and outputs a line release signal to the control circuit 6a. When the control circuit 6a receives this line release signal, the magnetic tape drive mechanism 25.
26 to stop recording and prepare for the next answering call.

Also, if the answering button on the operation unit 22a of the base station 1a or the operation unit 23a of the mobile station 2a is pressed again, the base station 1a
The control circuit 6a controls the magnetic tape drive circuits 25 and 26, cancels the answering mode, and restarts power supply to the wireless receiving circuit 11 of the mobile station 2.

Furthermore, a case will be described in which a message regarding the caller's business is played back when the caller is away.

First, when reproducing the business message from the base station 1a,
When the playback button on the operation unit 22a of the base station 1a is pressed, the control circuit 6a is activated by the magnetic tape drive circuit 26.
, and reproduces the recorded caller's message and outputs it to the speaker 5.

Further, when the fast forward button, rewind button, double speed playback button, etc. of the operation section 22a is pressed, the control circuit 6a controls the magnetic tape drive circuit 26 to fast forward, rewind, double speed playback, etc. of the message. I do.

Next, when reproducing the business message from the mobile station 2a,
When the playback button on the operation unit 23a of the mobile station 2a is pressed, the control circuit 6a causes the wireless transmission circuit 17 to transmit this information via the antenna 10 and the wireless line 3.

The control circuit 6a of the base station 1a receives this via the antenna 9 and the wireless receiving circuit 7, drives the magnetic tape drive mechanism 26, reproduces the message, and transmits the message to the wireless transmitting circuit 8,
It is transmitted to the wireless line 3 via the antenna 9.

The radio receiving circuit 11 of the mobile station 2 receives this via the antenna 10 and outputs the message to the receiver 14 via the low frequency amplifier circuit 13.

Further, when a fast forward button, rewind button, double speed playback button, etc. on the operation unit 22a is pressed, press information is transmitted from the mobile station 2a to the base station 1a, and the control circuit 6a of the base station 1a
, the magnetic tape drive mechanisms 25 and 26 of the base station 1a can be controlled by the operation unit 23a of the mobile station 2a. or,
Calling from mobile station 2a.

Incoming calls, redial hold, and speed dial operations can be performed in the same way as before.

As described above, according to the above embodiment, the cordless telephone is equipped with an answering function that can record and play back business messages from callers who are absent, and furthermore, the cordless telephone is equipped with an answering function that can record and play back business messages from callers who are absent, and furthermore, can receive messages from either the base station 1a or the mobile station 2a. Since the answering function can be operated, the answering function can be used at any location away from the base station 1a.

In addition to the above-mentioned embodiments, it is possible to provide a call recording function to record the contents of a call, a message function, etc., and configure it so that it can be operated from both the base station and the mobile station. By providing a means for counting the number of automatic call receptions and a means for displaying the number of automatic call receptions on the mobile station, there is also an effect that the mobile station can know the number of automatic call receptions.

Effects of the Invention As is clear from the embodiments described above, the present invention includes a first means for automatically receiving a call based on an incoming call signal from the telephone line, and a response message that is stored in advance in a base station connected to a telephone line. , a second means for transmitting the response message to the telephone line; and a third means for recording the voice signal from the telephone line after a certain period of time after transmitting the response message. and the first means. Second. Third
The mobile station that performs wireless communication with the base station is provided with means for controlling the first means. Second. - Since it is equipped with a means for controlling the third means, it is possible to use the answering machine function even with a cordless telephone device, and furthermore, it has the effect that various functions can be operated at any location, and response messages can be recorded and business messages can be played back.
