Abstract

PURPOSE:To recognize from whom a telephone call comes by recording a message of 'Hello' to a voice signal recording means and reproducing the voice even if an opposite party listens to a reply message and hooks on its handset. CONSTITUTION:Since a reply message transmission means 8 receives a reply command signal outputted from a voice signal detection means 7 in the automatic answering mode and sends a prescribed reply message to a telephone circuit, a caller gives a message of 'Hello' because of no reply from the called party for a while and the message is recorded by a voice signal recording means 6. Thus, even if the caller listens to the reply message and hooks on its handset, at least the voice of 'Hello' is recorded in the voice signal recording means 6 without fail, and it is recognized from whom the telephone call comes by reproducing the voice.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an answering machine equipped with a recording means for recording a caller's business.

<Prior Art> Conventionally, when this type of answering machine receives a call in answering mode, it first sends a response message to the other party, and starts recording by the recording means at the same time as or after the response message is sent. It is common to do so.

<Problem to be solved by the invention> By the way, when the caller hears the response message and realizes that the caller is not home, the caller often hangs up, and in such cases, the above-mentioned conventional answering machine However, there was a problem in that it was not possible to record not only the caller's business but also even the slightest voice of the caller, making it impossible to know who was calling. In such cases, if it were possible to record even a small amount of the other party's voice, it would be convenient to know who was calling from the voice.

Therefore, the purpose of this invention is to make it possible to record even a small amount of the other party's voice even if the other party hangs up after listening to the response message, so that it is possible to know who called. The purpose of this service is to provide an answering machine that can be used to answer calls.

Means for Solving the Problems> In order to achieve the above object, the present invention transmits a response message to the telephone line when the incoming call detection means detects an incoming call in the answering machine mode, and also transmits a response message to the telephone line via the telephone line. In an answering machine configured to record voice signals sent, the incoming call detection means starts recording at the same time as detecting an incoming call, and the voice signal recording means records the voice signals sent via the telephone line. , audio signal detection means for detecting the audio signal and outputting a response command signal when the audio signal of a predetermined level or higher continues for a predetermined time; The present invention is characterized by comprising a response message sending means for sending a response message to a telephone line.

<Operation> In the answering mode, when the incoming call detection means detects an incoming call, the audio signal recording means starts recording at the same time.

On the other hand, the person who is calling the other party does not receive a response for a while, so the person calls out to the other party using words such as ``Moshimoshi.'' Then, the audio signal recording means records the audio signal, and the audio signal detection means detects the audio signal, and if the audio signal is a signal of a predetermined level or higher that continues for a predetermined time, a response command signal is sent. Output. Then, upon receiving the response command signal, the response message sending means 1 sends a predetermined response message to the telephone line.

Therefore, even if the other party hangs up after hearing the above-mentioned response message, the voice signal recording means will have recorded the words "moshi-moshi", and by playing back the voice, it will be possible to determine who is calling. can be known.

<Example> Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

FIG. 1 is a block diagram showing the circuit configuration of an embodiment of the present invention.

In Figure 1, 1 and 2 are the tip and ring of the input terminal of this answering machine, 3 is an incoming call detection circuit that converts the ringing tone from the telephone line into pulses, 4 is a line closing circuit, and 5 is a voice transmission circuit. A speech network that performs 2-wire/4-wire conversion for receiving calls, 6 a business recording circuit for recording the received voice from the speech network 5, 7 detecting the received voice and setting the level of the received voice to a predetermined level. 8 is a response message circuit for outputting a response message to the telephone line via the speech network 5; 9 is a CPU;
It is. The message recording circuit 6 and the response message circuit 8 may be either an IC (integrated circuit) recording type or a magnetic tape type.

Further, the CPU 9 is composed of the following: That is, the incoming call detection means 11 counts the pulses from the incoming call detection circuit 3 and determines that there is an incoming call when a preset number of pulses are counted, and the incoming call detection means 11 controls the line closing circuit 4 to close the line. H (high) outputted by the line closing means 12 which performs this, the matter recording control means 13 which controls the matter recording circuit 6, the response message control means 14 which controls the response message circuit 8, and the voice detection circuit 7. After receiving the signal, H (
It is comprised of a voice detection means 15 that outputs a response command signal when the state (high) continues for a predetermined period of time, and a switch control means 16.

In the above configuration, when a call is received from outside, the incoming call detection circuit 3 converts the ringing tone into pulses and outputs the pulses to the incoming call detection means 11. The incoming call detection means 11 counts the number of pulses, and when it reaches a predetermined number, determines that there is an incoming call, and notifies the line closing means 12 and the message recording control means 13 of this via the switch control means 16. Inform. Then, the line closing means 12 controls the line closing circuit 4 to close the line, and at the same time, the message recording control means 13 controls the message recording circuit 6 to start recording.

When the caller receives no response from the other party's phone, he/she calls out something like "Moshi-moshi." This audio signal is outputted from the receiving output of the speech network 5 and recorded by the business recording circuit 6, while its level is detected by the audio detection circuit 7. As shown in FIG. 2, the voice detection circuit 7 outputs an H (high) voice detection output to the voice detection means 15 if the level of the voice input "Moshimoshi" is higher than a predetermined level. When the H input continues for a predetermined time, the voice detection means 15 outputs a response command signal to the response message control means 15 via the switch control means 16. The response message control means 15 controls the response message circuit 8 using this response command signal, and transmits the response message to the speech network 5, the line connection circuit 4, and the input terminal 1.
2 to the telephone line.

This response message has the content, for example, ``I am away from home at the moment.If you have business, please let me know your business.'' When the other party hears this response message, the other party hangs up knowing that the other party is not home, or informs the other party of necessary matters.

Then, when the recording by the message recording circuit 6 elapses for a certain period of time or the other party's telephone is on-hook, the message recording control means I3 stops the message recording circuit 6, and at the same time, the line closing means 12 The line closing circuit 4 is controlled to open the line.

The message recording circuit 6 always records at least the voice of an invitation such as "Hello," even if the other party hangs up without informing them of the business, so this voice can be played back later. By doing this, if you receive a phone call from an acquaintance, you can know who called from the voice.

<Effects of the Invention> As is clear from the above, in the answering machine of the present invention, in the answering machine mode, the voice signal recording means starts recording at the same time as the incoming call detecting means detects an incoming call, and the voice signal is sent via the telephone line. While the voice signal detection means detects the voice signal and outputs a response command signal when the voice signal of a predetermined level or higher continues for a predetermined time, the response message sending means detects the voice signal and outputs a response command signal. Since a predetermined response message is sent to the telephone line upon receiving the response command signal outputted by the voice signal detection means, it is possible to receive a response message from the other party when the other party makes a call and there is no response from the other party for a while.
Since the call is made with words such as "Moshi-moshi" and these words are recorded by the voice signal recording means, even if the other party hangs up after hearing the response message, the voice signal recording means will at least say "Moshi-moshi". Voice is always recorded, and by playing back this voice you can find out who is calling.
