CONSTITUTION:A reply message is simultaneously recorded on a recording tape 13 and a solid-state memory 7, a voice message is read out of the solid- state memory 7 with respect to the arrival of a call normally and used for reply, and when the content of the solid-state memory 7 is lost due to interruption of power, it is required to dub the reply message recorded on a recording tape 13 to the solid-state memory 7. When power supply is restored, a control computer is reset to rewind the recording tape 13 and the content of the tape 13 is reproduced, a tone signal is detected and the content is automatically dubbed to the solid-state memory 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an answering machine for recording / reproducing a reply message, and more particularly to an answering machine in which a reply message together with a tape can be recorded in a solid-state memory.

[0002]

2. Description of the Related Art An answering machine of a type in which a response message is recorded / reproduced by a solid-state memory and simultaneously stored in a tape is known, and in this kind of telephone, a RAM in a control microcomputer is generally backed up for a long time. There is no backup on the solid-state memory side that records and plays back response messages. Therefore, for example, the response message recorded in the solid-state memory is lost due to power failure or other reasons, and in such a case, the response message recorded on the tape is dubbed to the solid-state memory. Conventionally, the dubbing stores and manages the start position and the end position of the response message by the count value of the reel pulse of the cassette mechanism.

[0003]

However, the mechanism of the cassette mechanism has problems such as backlash, slippage, and tape elongation, and the reel pulse is one pulse at 0.5 second intervals. The position on the tape corresponding to the count value changes each time recording and reproducing are performed, and it is difficult to accurately manage the start and end positions of the recorded response message on the tape. Therefore, when dubbing from the tape to the solid-state memory, there is a problem that the beginning portion and the end portion of the response message are dropped and dubbed. Furthermore, once the cassette is pulled out, there is a problem in that the recording position of the tape and the reel pulse count value cannot be matched at all and the response message cannot be reproduced.

As a technique similar to the present invention, for example, in JP-B-63-58419, a cue signal is recorded simultaneously with a response message on a tape medium.
After detecting the reproduced cue signal during the confirmation operation of the response message, the response message is written in the solid-state memory, and the answering machine recording operation is performed based on the response message written in the solid-state memory thereafter. The device exists.

Certainly, the above-mentioned technique is similar to the present invention in that the cue signal is used for the cueing of the response message, but in the prior art, the cue signal is simply used for confirming the response message recorded on the tape side. A response message is recorded on the solid-state memory side by using a signal. Not only does the step of confirming the tape always be required when recording on the solid-state memory side, but also the response message in the solid-state memory due to power failure etc. When the tape is lost or when the response message is rewritten when the tape is replaced, the head of the response message is still set by counting the number of rotations of the reel base. There is no solution to the drawbacks of technology.

Further, any of the above prior arts is configured to record the response message in a series after the response message is cued. For example, the response message is “Yes, Kyocera. If you make a recording like this, an unfamiliar caller may call "Hello Iwasaki." Between "Yes, Kyocera" and "I'm currently out ..." There is a case where it is desired to record the voice of the calling party, but such a function is not considered at all.

In view of the above-mentioned drawbacks of the prior art, the present invention enables accurate dubbing without any partial drop when recording a response message from the tape to the solid-state memory side at the time of power failure or tape exchange. The purpose is to provide a method. Another object of the present invention is to provide a recording / reproducing system capable of recording the voice of the calling party during the reproduction of the response message. Another object of the present invention is to provide a recording / playback system in which a plurality of response messages can be selected.

[0008]

According to a first aspect of the present invention, the response message erased at the time of power failure can be recorded in the solid-state memory when the power is restored, or the response message recorded on the tape exchanged at the time of tape exchange is automatically generated. In regard to an answering machine configured to be recordable in a solid-state memory, a tone signal is recorded at least at a response message recording start position, more preferably at the message recording start position, and at intermediate and end positions thereof when recording a response message. A tone signal writing means for writing on the tape side and a tone signal detecting means for detecting each tone signal writing position at the time of reproducing the tape are prepared, and recorded on the solid-state memory side due to a power failure, battery exhaustion or other power failure. If the response message is lost, it will be returned when the power is restored or the tape is replaced. It is characterized in that the response signal recorded on the tape side or one or a plurality of selected response messages is recorded in the solid-state memory while detecting the tone signal by the detecting means and locating the corresponding response message. .

[0009]

[Effect] According to the invention described in claim 1, it is possible to automatically reproduce the response message lost from the solid-state memory due to the power failure immediately after the power is restored. Therefore, even if the power failure occurs during the absence, the answering machine is recorded. There is no hindrance in carrying out. Moreover, the contents of the solid-state memory can be automatically rewritten when the tape is replaced, which does not bother humans. Further, since the response message is accurately cued by the tone signal when the power is restored or the tape is exchanged, there is no partial dropout when recording (dubbing) the response message.

By changing the type of the tone signal, it is possible to select a plurality of response messages recorded on the tape side and record them on the solid-state memory side. Furthermore, by setting a tone signal in the midway position of the response message, the voice of the calling side (the other side) can be recorded while the response message is being played during the answering machine answering operation while the response message is being recorded on the solid-state memory side. The pause time can be set, and by setting the pause time between the response messages of "Yes, I am Kyocera" and "I'm out now ...", the message "What if Iwasaki? It is preferable because it is possible to record this if there is a voice from the calling party. That is, the pause time can be set even if the contents of the solid-state memory are rewritten when the power is restored or the tape is replaced.

By using a DTMF signal as the tone signal and setting a recording code such as a start code, a pause code, an end code, the above operation can be performed more smoothly.

The operation during recording will be described below with reference to the recording operation timing chart of FIG. First, when the control microcomputer 10 is set to the recording state, the output of the tone signal generation circuit 8 is directed from the recording / playback head 4 to the recording tape via the recording amplifier 2 and the recording switch 3 according to an instruction from the control microcomputer 10. The tone signal for message start setting (D1) is recorded at 13.
(S1)

After the tone signal (D1) corresponding to the start signal is recorded for 2 seconds, voice input (E) from the microphone is performed.
Is input, an audio signal is recorded on the recording tape 13 from the recording / reproducing head 4 following the start signal, and is simultaneously written in the solid-state memory 7. When the pause instruction (B) is issued to the control microcomputer 10 after the end of the voice message, the output of the tone signal generation circuit 8 is paused from the recording / playback head 4 to the recording tape 13 via the recording amplifier 2 and the recording switch 3. Record the setting tone signal (D2) for 1 second.
In addition, the tone signal (D1, D2, D
3) is recorded, but the control microcomputer 10
Is not written in the solid-state memory 7. Therefore,
In the solid-state memory 7, only the voice message on the recording tape 13 is block-by-block as shown in FIG. 2 (F) (for example, "Yes, Kyocera" is message 1, "I'm out now ..." is message 2, Recording is performed in correspondence with a location (hereinafter referred to as a channel CH) separated by a start address and a stop address on the solid-state memory 7.
When the last voice input is completed, the end instruction signal (C) is sent from the control microcomputer 10 to the tone signal generation circuit 8
And the tone signal D3 for setting the end is recorded on the recording tape 13 for 2 seconds.

As described above, the tone signal has a start and end represented by a signal for 2 seconds and a pause represented by a signal for 1 second. With the above operation, a start sound, a pause sound, and an end sound are arranged on the recording tape 13 for each message as shown in FIG.

Next, FIG. 3 shows a state of the solid-state memory 7 during message reproduction. When the solid-state memory 7 is set to the reproducing state (H) according to the instruction of the control microcomputer, the pause time is set for each channel divided at the time of recording by the channel dividing function of the solid-state memory 7 as shown in (J) of FIG. Playback is sequentially performed to the last recording channel via.

As described above, the response message is recorded on the recording tape 13 and the solid-state memory 7 at the same time. Normally, a voice message is read from the solid-state memory 7 and responds to an incoming call. If the contents of the above are lost, it is necessary to copy the response message recorded on the recording tape 13 to the solid-state memory 7. In the embodiment, when the power is restored, the control computer is reset and the recording tape 13 is rewound, reproduced, the tone signal is detected, and the solid-state memory 7 is automatically dubbed.

FIG. 4 is an explanatory view of the dubbing operation from the recording tape 13 to the solid-state memory 7. The recording tape 13 has a start setting tone signal (D1), response messages 1, 2,
3. The pause setting tone signal (D2) and the end setting tone signal (D3) are recorded as shown in FIG. When the recording tape 13 is set to the playback state,
As shown in (L) of FIG. 4, the start setting tone signal (D
1) is detected. When the start sound D1 ends, the response message 1 is reproduced and the channel 0 of the solid-state memory 7 is displayed.
(M) is recorded, and the writing of the response message 1 is completed when the pause setting tone signal (D2) is detected.

Then, the pause setting tone signal (D
After the end of 2), the response message 2 is reproduced from the recording tape 13 and written to the channel 1 of the solid-state memory 7. Similarly, the response message 3 is reproduced and the channel 2 of the solid-state memory 7 is written, and the recording tape 1 is recorded.
At the same time as detecting the end sound D3 of 3, the writing to the solid-state memory 7 is completed. Solid-state memory 7 written as described above
Is reproduced, CH0, pause time, CH1, pause time, and CH2 are reproduced as shown in (N) of FIG.

FIG. 5 shows the recording tape 13 in the above embodiment.
FIG. 6 is an operation timing chart when the DTMF signal is used for the start sound, the pause sound, and the end sound to be written into. With the start of the recording state P, the DTMF signal S of the start code changes the address area CH0 of the recording tape 13 and the fixed memory 7.
, And then the response message 1 by voice input (T) is recorded on the recording tape 13, while the solid-state memory 7
Is the address area (C
Write message 1 in H1). Furthermore, following message 1, the pause code 1 is written to CH2 on the recording tape 13 by the DTMF signal, and subsequently message 2 by voice input T is written, and at the same time the pause code 1 is written to the solid-state memory 7.
Write message 2 in the memory area (CH3) specified in. Then, the message 3 is also written in the memory area (CH5) corresponding to the pause code 2 written in CH4 of the solid-state memory 7 at the same time as the recording tape 13, and after the completion of the message 3, the ending code is written only in the recording tape 13 by the DTMF signal. .

According to this embodiment, a plurality of messages can be recorded by using the DTMF signal as a start sound, a pause sound, and an end sound, and a specific message can be selected by assigning different DTMF signals to each message. Becomes That is, for example, it is possible to selectively record one or a plurality of response messages in the solid-state memory 7 in correspondence with the type of the start code, and set the pause time arbitrarily in accordance with the type of the pause code. It is also possible and other versatility is expanded. Although the code corresponding to the DTMF signal is recorded in the solid-state memory 7 in the above embodiment, it is not always necessary to record the signal indicating at least the start, the pause, and the end on the tape.

Next, the case where the recording tape is replaced will be described. When the cassette is replaced, the tape detection means 11 operates to detect that the cassette has been replaced, and the tape rewinding operation is performed. Replacement of a new cassette is divided into a case where a response message remains in the solid-state memory 7 and a case where the response message is lost. After the cassette exchange, if the response message remains in the solid-state memory 7, no processing is performed, but if the response message is lost, the LED is turned on and the response message needs to be recorded. Let me know.

When the cassette is replaced with the one in which the response message is recorded, reproduction is performed in the same manner as described above, the tone signals (D1 to D3) are detected, and the recording in the solid-state memory 7 is rewritten to the response message of the exchange tape. Therefore, according to the present embodiment, when dubbing the response message from the recording tape 13 to the solid-state memory 7 when the power is turned off or the recording tape 13 is replaced, it is possible to perform accurate dubbing without partial dropout.

As a method of recovering the response message in the solid-state memory 7 when the power is cut off, a power cut detection means and a power restoration detection means are provided, and it is confirmed that the response message is lost and a dubbing process is performed. Is also good.
