JPH0496556A - Automatic answering telephone set - Google Patents

Abstract

PURPOSE:To squeeze a silence part and to attain efficient recording when a voice from an opposite party is consecutive by recording a voice signal of a prescribed level or over as a message. CONSTITUTION:When a call comes, it is received automatically through a speech network 7, and a reply message stored in a RAM 3 in advance as a digital data is sent through a D/A converter 12. After the transmission of the reply message, a message from the opposite party is recorded, but the recording is not immediately implemented and an allowable wait time when the silence state continues is set at first, a level detection circuit 10 monitors a signal level and when a signal of a prescribed level or over comes, it is discriminated to be the presence of a message and it is recorded. When the level is a prescribed level or below, the recording is again stopped.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an answering machine.

[Prior Art] When a conventional answering machine receives a call while the answering machine is set to answering mode, it automatically receives the call, sends a prepared response message to the other party, and then sends the other party's message.・Record the message on magnetic tape, audio IC, etc. The recorded business message can then be generated later and the telephone conversation can be listened to.

[Problems to be Solved by the Invention] However, in the double conventional example, when recording a business message, the recording γf operation is performed even when no message is sent from the other party, that is, when there is no sound. This has the disadvantage that silent recording portions occur in the limited area of the recording device, reducing the effective message recording time and, as a result, reducing the number of recordings.

SUMMARY OF THE INVENTION An object of the present invention is to provide an answering machine that can record only valid business messages and allow the recording device to function efficiently.

[Means for Solving the Problems] The present invention is characterized in that when an answering machine records a business message, a voice signal of a certain level or higher is recorded γf.

Further, the present invention is characterized in that when recording a business message on a magnetic tape, the recording head is moved to a recording preparation position of the magnetic tape in advance, and when an audio signal is detected, the magnetic tape starts running. do.

[Function] In the present invention, by recording an audio signal of a certain level or higher as a business message, even if the audio from the other party is intermittent, silent parts can be eliminated and recording can be performed efficiently.

Furthermore, in the case of recording business messages on magnetic tape, by moving the recording head to the recording preparation position in advance, recording can be started quickly and the business message can be reliably recorded from the beginning.

[Embodiment] FIG. 1 is a block diagram showing an embodiment of an answering machine using IC recording.

The control section 1 has a function as a main control section of the answering machine, and is composed of a microprocessor and the like.

ROM2 is a memory that stores a control program for the control unit 1, and RAM3 is used for the work area of the control unit 1, a telephone number buffer for calling, a response message area, a reception message area, etc. This is the memory that will be used.

Further, the operation section 4 is used to perform various operations on the answering machine, and the display section 5 is used to display operation guidance and the status of the telephone.

Furthermore, this telephone includes a micro for recording response messages, a speech network 7 for closing the telephone line and converting 2-to-4 wires, etc., a dialer 8 for sending a dial signal when making a call, and a dialer 8 for sending and receiving calls. a handset 9, and
A level detection circuit 10 that detects a signal at a certain level, an A/D converter 11 that converts an audio signal into digital data, and a D/A converter 1 that converts digital data into an audio signal.
2nd class is provided. Also, Speech Network 7
A telephone line 13 is connected to.

In the present embodiment, the A/D converter 11 converts the audio on the line 134- into digital data and stores it in the RAM 3, thereby recording the message when the user is away.

Note that among the signal lines in the figure, thick lines indicate audio signal lines, and hatched lines indicate signal lines of A/D-converted digital data.

FIG. 2 is a flowchart illustrating the operation of such a telephone in the absence mode.

However, it is assumed that the response message has already been recorded and the telephone has been set to answering mode.

First, when a call arrives (Sl), it is automatically received through the speech network 7 (S2), and
3, the response message stored as digital data is sent out through the D/A converter 12 (S3).

After sending the response message, the message from the other party will be recorded, but the recording operation will not be performed immediately, but after setting the allowable waiting time in case there is continued silence (
S4), the signal level is monitored through the level detection circuit 10, and when a signal of a certain level or higher comes (S5)
), it is determined that there is a message from the other party and recording is performed (S6).

Then, when the F level reaches a certain level (S7), recording is stopped again (S8).

Thereafter, this operation is repeated, and when the silence continues for a certain amount of time (S9), the line is released (SIO).
Return to standby state.

FIG. 3 is a block diagram showing an embodiment of an answering machine using magnetic tape.

This telephone has the configuration shown in FIG.
A converter 12, a response message area and a business message area in the RAM 5 are deleted, and a magnetic tape recording/playback device 14 is provided for recording and reproducing the response message and business message on a magnetic tape. It is. Further, the magnetic tape recording/reproducing device 14 has a structure in which recording and reproducing functions are independent of each other.

Note that the other configurations are the same as those shown in Figure 1, and are given the same reference numerals.

FIG. 4 is a flowchart illustrating the operation of such a telephone in the absence mode.

As in the case of the first embodiment, it is assumed that the response message has already been recorded on a magnetic tape by the magnetic tape recording/reproducing device 14 and that the telephone is set to the answering mode.

First, when a call is received (S21), it is automatically received through the speech network 7 (S22), and the phone is recorded/recorded.
Start up the playback device 14 and send out a response message (S
23). After sending this response message, the recording head of the magnetic tape recording/playback device 14 is set to the recording preparation position on the magnetic tape so that the message can be recorded immediately, and the magnetic tape is put into a recording start state. Does not run the tape and waits in a pause state (S24)
.

Then, in the same manner as in the first embodiment, after setting the allowable waiting screen interval when silent IEs continue (S25),
Monitor the signal level through the level detection circuit 10,
When a signal is received that is above a certain level (326),
When it is determined that there is a message from the other party, the magnetic tape is run and recorded (S27). Then: - When the level reaches a certain level (328), the magnetic tape is stopped by +1 and becomes a pause state (524).

Thereafter, this operation is repeated, and when the silent state continues for a certain period of time (S29), the line is released (530), the magnetic tape recording/playback device 14 is unset (S31),
Return to standby state.

[Effects of the Invention] As explained above, according to the present invention, by recording a voice signal north of a certain level as a business message, when the voice from the other party is intermittent, the silent part can be closed and the message can be recorded. This has the effect of making recording more efficient.

In addition, in devices that record business messages on magnetic tape, by moving the recording head to the recording preparation position in advance, recording can be started smoothly and the business message can be reliably recorded from the beginning. be.
