Abstract

PURPOSE:To erase the recording completing signal by running the tape in the reverse direction after the recording completing signal is detected, when the starting position of the recording completing signal is detected, recording and running the tape in the forward direction and starting to write the response message completing signal. CONSTITUTION:When the response message is dubbed by the remote action, a caller, who finishes to tell the new response message, sends the prescribed DTMF signal to show the completion of the recording and immediately, then the recording action of a deck 6 is stopped, and thereafter, continuously, said deck 6 is reversely run and operated. For a prescribed time T only equivalent to the detecting time of the above-mentioned recording completing signal, the reverse direction running is executed, and then, the deck 6 is recorded and operated again, a response message completion signal generating circuit 14 to generate the prescribed audible signal is driven and the response message completion signal is written. Thus, the recording completion signal, which is recorded once, is erased, and in succession to the response message, the response message completion signal is written.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone answering machine, and more particularly to a telephone answering machine having a function of recording a response message via a telephone line by remote operation.

[Conventional technology]

Conventional remote control methods for answering machines include the so-called bee-palace method, which uses [)TMF signals developed by Punshuong et al., as remote signals to instruct various remote operations, and patented frequency signals sent from a dedicated oscillator. However, when recording a response message by remote operation, when the response message is finished speaking, a predetermined remote signal is sent as a recording completion signal to notify this. the result, .

Upon receiving this, the answering machine side subsequently writes response message end No. 1g. Later, when an incoming call is automatically answered and a response message is reproduced and transmitted, the reproduction and transmission operation is stopped when the response message end signal is detected.

[Problem that the invention seeks to solve]

However, in the case of the bee-palace method, and even in the case of a dedicated oscillator, as long as an audible frequency remote signal is used, when a response message is recorded by remote operation, following the response message itself, the above-mentioned recording end occurs. The signal is also recorded. As a result, this may be played when answering an incoming call, causing discomfort or anxiety to the other party, or may be misunderstood as the start sound for recording a message, causing the caller to record the message before recording is complete. There was a risk that the beginning part would not be recorded because the speaker would start speaking.

[Means for solving problems]

In order to solve these problems, the present invention provides a detecting means for detecting the start position of the recording end signal, a tape recorder that runs the tape in the reverse direction after detecting the recording end signal, and an output of the detecting means that occurs when the recording end signal is detected. control means for running the tape in the forward recording direction and starting writing of the response message end signal when the response message ends.

[Operation] The response message end signal is overwritten on the recording end signal, and the recording end signal is erased.

〔Example〕

FIG. 1 is a block diagram showing one embodiment of the present invention. The line terminal connected to the telephone line is shown in the figure, and the telephone is shown at the bottom.

On the other hand, 1 is a control circuit consisting of a microcomputer equipped with a processor-length unit such as a well-known microprocessor, memory, etc., and the answering mode can be set by the answering switch of the key switch section 2 according to a pre-stored program. If the incoming call detection circuit 3
When an incoming call is detected, the following control operations are performed. That is, the control circuit 1 first operates the AIJ relay, thereby switching the connection of the contact a to the line transformer T side, thereby closing the DC loop. Next, the control circuit 1 causes the response message cassette deck 6 to play back via the deck controller 5 and turns on the analog switch 7, so that the previously recorded response message is transferred from the head 8 to the amplifier 9 and The signal is sent to the telephone line via the print circuit 10. If a predetermined remote signal is detected by the DTMF signal detection circuit 11 during sending of the response message, the control circuit 1 immediately stops sending the response message and performs a predetermined remote operation in accordance with the remote signal.

FIG. 2 is a flowchart showing the response message (OGM) recording processing operation. This is to dub the response message by remote operation.When a remote signal instructing to record a message is detected and the program execution shifts to this processing program, the control circuit 1 immediately activates the deck 6. A rewinding operation is performed (step 101). When the tape has been rewound to the beginning (step 102), the rewinding operation is stopped (step 1).
03), although not shown in the figure, a predetermined oscillator sends out a ready tone to the telephone line (step 104). Next, the control circuit 1 puts the deck 6 into recording mode and turns on the analog switch 12, so that the response message arriving on the telephone line is transmitted to the hybrid circuit 10 and the amplifier 13.
The response message is transmitted to the head 8 via the voice recorder, and a dubbing recording of the response message is performed (step 106). When the caller finishes speaking the new response message, the caller sends a predetermined DTMF signal indicating the end of recording, and upon detecting this (step 106), the control circuit 1 immediately stops the recording operation of the deck 6. After that (step 107), the deck 6 is subsequently caused to move backwards (step 108). Then, after traveling in the reverse direction for a predetermined time T corresponding to the detection time of the recording end signal (step 109), after stopping the reverse traveling operation (step 110), the deck 6 is started to record again. The response message end signal generating circuit 14 that generates a predetermined audible signal is driven to write the response message end signal (step 111).
). As a result, the once-recorded recording end signal is erased, and a response message end signal is written following the response message.

When the remote operation is completed, the control circuit 1 restores the A relay 4 to open the DC loop, and then cues the response message to prepare for the next incoming call. When an incoming call is received, it is automatically answered in the same manner as described above, and a new voiced response message is sent to the telephone line. If no remote signal is received on the way, the control circuit 1 stops the reproduction and transmission operation of the response message when the aforementioned response message end signal is detected, and instead starts the recording operation of the message cassette deck 15. At the same time, the analog switch 16 is turned on.

As a result, the message from the caller is transmitted to the head 18 via the no-event circuit 10 and the amplifier 17, and is recorded.

In addition, after detecting the recording end signal of the response message, a high-speed rewinding operation may be performed in place of the reverse running operation at the same speed as the forward playback. In that case, the rewinding operation is performed only at a time corresponding to the time T during the reverse running operation, that is, at a time when the tape travels the same distance.

In the case of this embodiment, the start position of the recording end signal is indirectly detected by running backwards for a certain period of time corresponding to the detection time of the recording end signal, so the waveform of the recording end signal is not distorted. , the actual detection time is T
+α, and due to this detection delay, there is also a delay in stopping the recording operation, and even if the device runs backwards for a certain period of time T, it does not return to the correct recording end signal start position, and a portion of the recording end signal remains without being completely erased. Also 11) get.

In order to avoid this, the analog switch 19 is turned on at the same time as the deck 6 is moved in the reverse direction as shown in FIG. Then, as shown in FIG.
), and the recording end signal detected by the DTMF signal detection circuit 11 is interrupted (step 210).
The reverse running operation is stopped (step 211), and a response message end signal is written (step 212).

However, in the direct detection method in which the recording end signal is directly monitored and the start position is detected while the vehicle is traveling in reverse, the determination of whether the predetermined time T has elapsed is not necessarily necessary and may be omitted. In addition, in FIG. 3, steps 201 to 2
The process in step 07 is completely similar to the process in steps 101 to 107 in FIG.

〔Effect of the invention〕

Although an example in which a DTMF signal is used as a remote signal has been described above, the present invention is not limited to this. Even if a dedicated oscillator is used, similar problems occur as long as the audio frequency signal is used as a remote signal, and therefore, the present invention can be applied to obtain similar effects.
