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 and playing back a response message, and more particularly , to a power supply after power-off.
Built-in response message after power recovery and recording tape
The present invention relates to an answering machine configured to be able to record a response message after a cassette has been exchanged from a recording tape to a solid-state memory.

[0002]

2. Description of the Related Art An answering machine of the type in which a response message is recorded and reproduced by a solid-state memory and simultaneously stored on a tape is known. In such a type of telephone, in order to back up a RAM in a control microcomputer for as long as possible, a telephone is generally used. No backup is made on the solid-state memory side for recording and reproducing response messages and the like. For this reason, the response message recorded in the solid state memory is lost due to, for example, a power failure or other circumstances, and in such a case, the response message recorded on the tape is dubbed to the solid state memory. Conventionally, in the dubbing, the start position and the end position of the response message are stored and managed by the count value of the reel pulse of the cassette mechanism.

[0003]

However, the cassette mechanism has problems in terms of mechanism, such as looseness, slippage, and tape expansion. In addition, since one reel pulse is spaced at 0.5 second intervals, the reel pulse cannot be used. The position on the tape corresponding to the count value changes each time recording and playback is performed, and it has been difficult to accurately manage the start and end positions of the recorded response message on the tape. For this reason, when dubbing from the tape to the solid-state memory, there is a problem that the beginning and end of the response message are cut off and dubbed. Further, once the cassette is pulled out, there is no correspondence between the recording position of the tape and the reel pulse count value, so that there is a problem that the reproduction of the response message becomes impossible.

As a technique similar to the present invention, for example, in Japanese Patent Publication No. 63-58419, a cue signal is recorded simultaneously with a response message on a tape medium. After the detection, the response message is written in the solid-state memory, and thereafter, there is an apparatus that performs an answering machine recording operation based on the response message written in the solid-state memory.

Although the above technique is apparently similar to the present invention in that the cue signal is used to locate the beginning of the response message, the prior art merely uses the cue signal when confirming the response message recorded on the tape side. A response message is recorded on the solid-state memory using a signal. Not only does the tape need to be checked at the time of recording on the solid-state memory, but also the response message in the solid-state memory due to a power failure or the like. In the case where the response message is lost or when the response message is rewritten at the time of tape replacement, the head of the response message is configured to be counted by counting the number of revolutions of the reel base. There is nothing to solve the shortcomings of technology.

Further, in any of the above prior arts, after locating the response message, the response message is recorded in a series. For example, when the response message is "Yes, Kyocera. If you are an unfamiliar caller, the caller may say "Hello Iwasaki." Between "Yes Kyocera" and "I'm out now ..." In some cases, it is desired to record the voice of the caller, but such a function is not considered at all.

SUMMARY OF THE INVENTION In view of the drawbacks of the prior art, the present invention provides a recording / reproducing method which enables accurate dubbing without any partial omission when recording a response message from the tape to the solid-state memory at the time of power failure or tape change. The purpose is to provide a scheme. Another object of the present invention is to provide a recording / reproducing method which can record the voice of the caller while reproducing the response message.

[0008]

A first aspect of the present invention relates to an answering machine which is configured so that a response message erased when a power supply is cut off at the time of a power failure or the like can be automatically recorded in a solid-state memory when the power is restored. The invention according to claim 2 relates to an answering machine in which a response message recorded on a recording tape exchanged when exchanging a cassette incorporating a recording tape can be recorded on a solid-state memory. In a recording / playback method of an answering machine configured to be recordable in a solid-state memory together with a recording tape, when recording a response message, at least a response message recording start position, an end position, and the start position.
Playing a response message as needed between and the end position
Set the pause time during which the caller's voice can be recorded.
And a tone signal writing means for writing a tone signal to the recording tape side at a recording position, and a tone signal detecting means for detecting the tone signal writing position when reproducing the recording tape.

[0009] In both of the inventions, a pause for recording the voice of the calling side can be provided at an intermediate position of the response message if necessary .
And a tone signal detecting means for detecting the tone signal writing position during reproduction of the recording tape, while the response message is being reproduced during the answering machine operation while the response message is being recorded on the solid state memory side. The pause time during which the caller's (other party's) voice can be recorded can be set.

[0010] In addition, a first aspect of the present invention, a power outage young properly

EFFECT Therefore, in order to be able to reproduce claim 1 response message disappears from the solid-state memory by a power failure, according to the invention immediately automatically after power is restored, wherein even when it becomes a power failure during absence There is no hindrance in performing answering machine recording. Further, according to the second aspect of the present invention, the contents of the solid-state memory can be automatically rewritten when the tape is replaced , so that no human trouble is required. Also, answer message
When the message has disappeared, use display means to indicate that fact.
The user is aware of this display and
Can be encouraged.

In both of the inventions, since the response message is accurately cueed by the tone signal when the power is restored or the tape is replaced, a partial omission or the like occurs when the response message is recorded (dubbed). There is nothing. In both of the inventions, by changing the type of the tone signal, a plurality of response messages recorded on the tape side can be selected and recorded on the solid-state memory side.

[0015] Further, a call is issued in the middle of the response message.
By setting a pause tone signal that allows the caller's voice to be recorded , the caller's (other party's) voice is played during the answering message playback during the answering machine operation while the answering message is being recorded on the solid state memory side. The pause time that can be recorded can be set. By setting the pause time between the above-mentioned response messages of "Yes, Kyocera" and "I'm out now ...", the pause time can be set between the response signals. "Hello, Iwasaki." If there is a caller's voice, this can be recorded, which is preferable. That is, even when the contents of the solid-state memory are rewritten when the power is restored or when the tape is replaced, the pause time can be set.

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

Reference numeral 2 denotes a recording amplifier, 3 denotes a recording switch, 4 denotes a recording / reproducing head, 5 denotes a reproducing switch, 6 denotes a reproducing amplifier, and 7 denotes a solid-state memory, for example, a recording / reproducing LSI. Reference numeral 8 denotes a tone signal generating circuit whose output terminal is connected to the input side of the recording amplifier 2 and the output side of the reproducing amplifier 6. Reference numeral 9 denotes a tone signal detection circuit whose output terminal is connected to the output side of the reproduction amplifier 6. 10 is a control microcomputer, 11 is a recording tape detecting means, 12 is an LED for notifying that the response message in the solid-state memory has disappeared, and 13 is a recording tape.

The operation at the time of 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 generating circuit 8 is transmitted from the recording / reproducing head 4 via the recording amplifier 2 and the recording switch 3 to the recording tape by the instruction of the control microcomputer 10. At step 13, a message start setting tone signal (D1) is recorded.
(S1)

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

As described above, the tone signal indicates the start and the end by a signal for 2 seconds and the pause by a signal for 1 second. By the above operation, the start sound, the pause sound, and the end sound are arranged on the recording tape 13 as shown in FIG.

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

As described above, a response message is simultaneously recorded on the recording tape 13 and the solid-state memory 7, and a voice message is normally read out from the solid-state memory 7 to respond to an incoming call. Is lost, it is necessary to dub the response message recorded on the recording tape 13 to the solid-state memory 7. In this embodiment, when the power is restored, the control computer is reset, the recording tape 13 is rewound, reproduced, the tone signal is detected, and dubbing to the solid-state memory 7 is automatically performed.

FIG. 4 is an explanatory diagram of the dubbing operation from the recording tape 13 to the solid-state memory 7. The recording tape 13 has a tone signal (D1) for start setting, response messages 1, 2,
3. A tone signal (D2) for pause start setting and a tone signal (D3) for end setting are recorded as shown in FIG. 4 (K). When the recording tape 13 is set to the playback state, a start setting tone signal (D1) is detected as shown in FIG. When the start sound D1 ends, the response message 1 is reproduced, recorded on the channel 0 of the solid-state memory 7 as shown in FIG. 4 (M), and the writing of the response message 1 is completed by detecting the pause setting tone signal (D2). I do.

After the completion of the pause start setting tone signal (D2), the recording tape 13 of the response message 2
And writing to channel 1 of the solid-state memory 7 is performed. Similarly, the response message 3 is reproduced,
The writing to the channel 2 of the solid-state memory 7 is performed, and the writing to the solid-state memory 7 is ended simultaneously with the detection of the end sound D3 of the recording tape 13. When the solid memory 7 written as described above is reproduced, CH0, pause time, CH1, pause time, and CH2 are reproduced as shown in FIG.

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

According to this embodiment, a plurality of messages can be recorded by using a DTMF signal as a start sound, a pause sound, and an end sound, and a specific message can be selected by assigning a different DTMF signal to each message. Becomes That is, for example, one or more response messages can be selectively recorded in the solid-state memory 7 according to the type of the start code, and the pause time can be arbitrarily set according to the type of the pause code. 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-described embodiment, it is not always necessary to record the code representing at least the start, pause, and end on the tape.

Next, the case where the recording tape is replaced will be described. When the cassette is replaced, the tape detecting means 11 operates to detect that the cassette has been replaced, and the tape is rewound. The 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. If a response message remains in the solid-state memory 7 after the cassette replacement, no processing is performed. However, if the response message is lost, the LED is turned on to record the response message. To inform.

When the response message is replaced with the cassette on which the response message has been 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 on 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 when the recording tape 13 is replaced, accurate dubbing without partial omission can be performed.

[0029] As the recovery method of the response message in the solid-state memory 7 at the time of power-off, power-off detecting means, the power restoration detection means is provided, to perform the dubbing process to confirm that the response message is lost Can be.
