Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cordless answering machine in which a base station and a mobile station are connected wirelessly.

BACKGROUND OF THE INVENTION FIG. 2 is a block diagram showing the general structure of a conventional cordless answering machine. A base station 1 in the upper part of the figure and a mobile station 2 in the lower part are connected by a wireless line 3. This wireless line 3 carries audio signals or various control signals using radio waves. The control signals include a connection operation signal that is sent from the mobile station to the base station and instructs the connection operation of the telephone line;
There is a dial signal that transmits to the base station the telephone number of the other party entered using the numeric keypad at the base station. The incoming call detection circuit 4 is connected to a telephone line, detects an incoming call signal from the other party, rings the ringer 5, and simultaneously notifies the control circuit 6 of the incoming call. The radio transmission circuit 7 transmits the voice signal sent from the telephone line via the communication circuit 8 and the control signal output from the control circuit 6 to the mobile station 2 from the antenna 9 as radio waves. The radio receiving circuit 10 receives and amplifies the audio signal or control signal transmitted from the mobile station 2 as a radio wave from the antenna 9. At the same time, external noise and external radio waves are detected and input to the control circuit 6 manually. The recording and reproducing circuit 11 has a response tape and a business tape, and the response tape side is connected to the telephone call circuit 8.
It is connected to the input side of the microphone 12 and has a function of reproducing a response message to the telephone line, a function of updating the response message, etc. The message tape side is connected to the output side of the communication circuit 8, and has the function of recording the message of the other party. The control circuit 6 includes each of the circuits 4゜7.8.1
0.11 to control each circuit, send and receive control signals to and from the mobile station 2, monitor the presence or absence of reception from the mobile station, detect whether or not a call is not possible, and detect whether or not a call is not possible. If possible, when there is an incoming call from the other party, the recording and reproducing circuit 11 is activated to cause the other party to send a response message and record the business message from the other party. The hook switch 13 is for closing the telephone line, and is opened and closed by the control circuit 6.

In the mobile station 2, the radio receiving circuit 14 receives the voice signal or control signal as a radio wave from the antenna 15, and the voice signal passes through the low frequency amplification circuit 16 and is converted into voice by the receiver 17. A control signal is manually input to the button control circuit 18. The voices of the users of the two mobile stations are converted into voice signals by the microphone 19, and transmitted as radio waves from the antenna 15 through the low frequency amplification circuit 20 and the radio transmission circuit 21.

Further, the control signal output from the control circuit 18 is similarly transmitted as a radio wave. The control circuit 18 is the radio receiving circuit 14
When receiving a signal indicating an incoming call, Rin rings 22 to notify the user.

It also controls each circuit 14, 16, 20, and 21, and sends and receives various control signals to and from the base station 1. Note that the mobile station 2 is cordless, uses a battery 23 as a power source, and is supplied with power via a power switch 24. Although not shown in the drawings, the power source of the base station 1 uses normal alternating current.

Next, the operation when there is an incoming call in the conventional example will be described. In the figure, when there is an incoming call from a telephone line, the incoming signal is manually detected by an incoming call detection circuit 4, and the output from this incoming call detection circuit 4 is input to a control circuit 6, and then sent to an antenna via a wireless transmission circuit 7. It is sent out via 9.

When the signal is received by the radio receiving circuit 14 via the antenna 15 of the mobile station 2, the control circuit 18 that receives the output signal from the radio receiving circuit 14 activates the ring 22 and outputs a ringtone. Notify the mobile station user of the incoming call.

Now, if the mobile station 2 is too far away from the base station 1 or if the battery 23 is out of power, it will be impossible to communicate between the two stations 1 and 2. The control circuit 6 of the base station 1 is always monitoring. When a call is received on the telephone line while communication is detected as impossible, the control circuit 6 closes the hook switch 13, activates the recording/playback circuit 11, and sends a response message to the other party (caller). It is designed to send and record messages from the other party. Note that although the recording/reproducing circuit 11 of this conventional example drives a response tape or a message tape by a drive circuit, other conventional examples also exist that use a semiconductor memory instead of the tape.

Problems to be Solved by the Invention However, with the above-mentioned conventional cordless answering machine, although the base station automatically answers when there is an incoming call from a caller when the base station and mobile station cannot communicate, the mobile station Since it is originally impossible to communicate with the base station, there was a problem that the user could not know whether or not the base station automatically responded when there was an incoming call, or how many times the call was received. .

The present invention solves such conventional problems, and when the base station and mobile station cannot transmit, the base station automatically answers the caller and records the number of recorded messages. To provide an excellent cordless answering machine capable of notifying a user of a mobile station at the time of recovery.

Means for Solving the Problems In order to achieve the above object, the present invention provides the base station with a counter that counts the number of business messages according to a command from a control circuit when communication failure is detected, and the mobile station A display device is provided for displaying the counter value received as one of the control signals according to a command from the control circuit.

The control circuit of the base station causes a counter to count the number of business messages recorded when the base station and mobile station cannot communicate, and transmits the count value to the mobile station as one of the control signals. . This transmission will take place when communication is restored.
The mobile station receives the signal, and the control circuit is displayed on the display.

Embodiment FIG. 1 is a block diagram showing the overall schematic configuration of a cordless answering machine according to an embodiment of the present invention. In the figure,
The same parts as in FIG. 2 showing the conventional example are given the same numbers.

The difference from the conventional example is that a counter 25 connected to the control circuit 6 of the base station 1 is provided, and when the control circuit 6 detects that the base station 2 and the mobile station cannot communicate, the telephone line When an incoming call signal is input from the recorder/player circuit 11, which sends out a response message and records a business message, the number of business messages is counted. This count value is sent out as one of the control signals via the radio transmitting circuit 7 and the antenna 9 according to a command from the control circuit 6.

Further, a 7SEGLED, which is a display 26 connected to the control circuit 18 of the mobile station 2, is provided, and displays this count value in response to a command from the control circuit 18 that has received the count value as one of the control signals. That's true.

Next, the operation when a call is received from the telephone line in the above embodiment will be explained. When there is an incoming call from the telephone line, the incoming call detection circuit 4 detects it and outputs a signal to the control circuit 6. At this time, the control circuit 6 sends a signal notifying the incoming call to the mobile station 2 via the radio transmitting circuit 7 and the antenna 9 as one of the control signals. However, in this transmission,
The control circuit 6 determines the availability of the radio line 3 based on the CD information from the radio receiving circuit 10, and when the radio line 3 is not available, the signal cannot be transmitted. Also, wireless line 3
Even if the base station 1 is vacant, the battery 23 of the mobile station 2 may be exhausted, or the distance between the base station 1 and the mobile station 2 may be insufficient due to the antenna 9.
15, or the mobile station 2 may not return a response signal to the base station 1. In this way, if the wireless line 3 is not full or if no response signal is returned, the control circuit 6 determines that communication is impossible, and closes the hook switch 13 in response to the incoming call. A recording/reproducing circuit 11 is caused to record a prerecorded response message. When the control circuit 6 detects the end of recording, it opens the hook switch 13 and instructs the counter 25 to count up. Since this command is issued every time there is an incoming call when communication is not possible, the counter 25 counts the number of recorded business messages. Thereafter, when communication between the base station 1 and the mobile station 2 is restored, the control circuit 6 transmits the count value of the counter 25 to the mobile station 2. This transmission is performed by the radio transmission circuit 7 of the base station 1, the antenna 9, the radio line 3, and the
The signal is transmitted via the antenna 15 and radio receiving circuit 14 of the mobile station 2, and is input to the control circuit 18 of the mobile station 2. Control circuit 18
transmits a reply signal indicating that it has received this count value to the base station 1 as one of the control signals, and also displays this count value on the 7SEG LED which is the display 26. When the base station 1 receives the reply signal, it sets the counter 25
Clear the count. Then, the base station and the mobile station return to the normal state where they can communicate and wait for an incoming call.

As explained above, according to this embodiment, the user of the mobile station 2 can use the 7SEG display on the display of the mobile station 2 after communication is restored.
Look at the count value displayed on the LED and check the number of business messages recorded while communication was unavailable (therefore,
You can check whether there is a recorded message or not.

In the above embodiment, the counter 25 of the base station 1 clears the count after communication is restored, but in other embodiments, the count is cleared only after a control signal to clear the count is issued from the mobile station side. is also possible.

Effects of the Invention As is clear from the above embodiments, the present invention allows the base station to automatically respond to incoming calls when transmission is not possible between the base station and the mobile station, and to record the number of recorded business messages on the mobile station side. Even if a call arrives without the mobile station user's knowledge and the base station automatically answers and a message is recorded without the user's knowledge, the recorded message will be displayed. The presence or absence of messages and the number of messages can be definitely notified to the user.
