Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an answering machine that allows the use of a call waiting service.

<Prior Art> A call waiting service is a call waiting service that, when a third party calls you during a call, puts the call on hold and allows you to talk to the third party. For example, as shown in Figure 2, telephones A, C, and D and telephone exchange equipment B
If A receives a call from D while A and C are talking, B sends an incoming call display sound (call waiting signal) to A. The operator of A listens to this call waiting signal, performs a hook operation, and sends out a flash signal. In response to this flanille signal, B puts C's line on hold and connects D's line to A, making it possible to talk to D.

Consider the case where a conventional answering machine is connected to such a call waiting service line. In FIG. 2, 8 is the 71st episode of the conventional answering machine. If the call is in normal mode and not in answering mode, the call will be switched by the catch call service. On the other hand, when 8 is in answering mode, when C calls, A sends a response message to C and then records the business message sent from C. D in the process
When 8 receives a call, B sends a call-waiting signal to A. If 8 is playing a response message, this call-waiting signal is mixed in with the response message, and 8 records the message. If the message is in progress, it will be recorded along with the message.

<Problems to be Solved by the Invention> By the way, in the above-mentioned conventional answering machine, when the above-mentioned call waiting signal is recorded, by playing it back, it is possible to detect when a third party has called during the call. However, since it is not designed to respond to the above-mentioned call waiting signal, even if a third party calls you during a call, you will not be connected to that third party. There was a problem that it was not possible to record business messages.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to respond to a call waiting signal even in answering mode when connected to a call waiting service line, and to respond to a call waiting signal when a call is received during a call.

Please record the message (first class message) if necessary. As a recording/playback device for such 8 types of response sentences and messages, in addition to the IC method such as the recorded voice analysis and synthesis circuit 5, a magnetic tape method can be considered. Cue self-interest Pi: From IC
The method is more effective (think of it as the T effect).

-1- The operation of the answering machine having the configuration described above will be explained below using the telephone Δ shown in FIG. 2 as shown in FIG.

Suppose that this telephone receives a call from 7u telephone C. Then, in Fig. 1, ) u talk line I
The ringing signal is guided to the ringing tone generation circuit I2 via the bridge rectifier circuit 11, and the ringing tone generation circuit I2
The ringing tone is output from the ringing tone detection circuit 13 and the ringing tone generator 14. The ringing tone generator R314 generates a ringing tone in response to this ringing tone. The ringing tone detection circuit 13 includes the ringing tone generation circuit 12 and the control circuit 1.
-1-, the signal from the recorded ringing tone generating circuit I2 is waveform-shaped as required, and then outputted to the ringing tone detection means 19.

The ringing tone detection means 19 is the ringing tone detection circuit I3.
In response to the signal from the system, the presence or absence of ringing tones, the continuity of the ringing tones, and the number of times since the arrival of the ringing tones are measured. When a predetermined number of rings has been reached, the line opening/closing signal generating means 16 is activated to open/close the line. The line is closed by circuit 3.

When the line is closed, the voice analysis and synthesis circuit control means 18 controls the voice analysis and synthesis circuit 5 to connect the voice IN AM
The data of the first or second response sentence stored in 9 is synthesized into voice and sent to the telephone line l via the speech network circuit 4. This response sentence should be conveyed to C via B. When A finishes sending the response sentence, it starts recording if recording is possible.

If A makes a call to Dh<A while A is sending a response to C or before the recording of the business message from C is completed, exchange B will send a catch-pong signal to 8. Be it.

This catch-phone signal is led to the call-phone signal detection circuit IO via the telephone line I, the bridge rectifier circuit 2, the line opening/closing circuit 3, and the speech network circuit 4, and the output of the call-phone signal detection circuit 10 is input to the catch-phone signal detection means 17. be done. When the catch-phone signal detecting means 17 determines that it is a catch-phone signal, it drives the voice analysis and synthesis circuit control means 18 to interrupt the current operation such as sending a response sentence or recording a business message.

Then, the voice analysis and synthesis circuit 5 plays a first message for call waiting, notifying C that there is a call from a third party.

When the first message for call waiting is finished being played to C, the line opening/closing signal generating means 16 or the line opening/closing circuit 3 is controlled to send a flash signal corresponding to a hook operation to the telephone line 1. Exchange B, which received this flanille signal, put C's line connected to A on hold and connected D's line to A. After that, A newly becomes the first or second
It performs normal answering operations such as playing a response from D and recording a message from D. During this answering operation, C
h<Exchange B puts C's line on hold until he hangs up.

When the answering operation for "2 minutes" is completed, the line opening/closing signal generating means 16 controls the line opening/closing circuit 3 again to send out a flanille signal to the telephone line.

Exchange B, which received this flash signal, connects C's line, which had been put on hold, to 8. After that, A plays a second call waiting message to C and
The rest of the house-sitting operations will be performed between the two.

In this way, if you receive a call from a third party while you are using answering machine with the other party, you can temporarily put the call with the other party on hold and use answering machine with that third party. After
Since the call is kept as an answering machine with the person who put the call on hold, it is possible to record not only the message of the other party during the call, but also the message of a third party.

・〈Effects of the Invention〉 As is clear from the above, the answering machine of the present invention is connected to a call waiting service line, and is capable of sending a response message to a called party and receiving a business message sent from the other party. When an answering machine such as recording is in progress, when a third party calls and a call-phone signal is sent, the call-phone signal detection means detects the call-phone signal, and the answering machine stop means detects the caller. During this period, the answering machine is stopped, and the message sending means sends a call-waiting message to the above line to notify the other party of the call from a third party, and then the line is opened/closed. The signal generating means is
Controls the line opening/closing circuit and sends a line opening/closing signal corresponding to a hook operation to the line, and when the line is connected to the third party, the answering machine operation starting means starts the answering machine operation from dawn. Since the device is configured to operate automatically, it is possible to record not only business messages from the other party during the call, but also business messages from a third party who called during the call.
