Abstract

PURPOSE:To hardly set the automatic answering mode except the user and to satisfy the specification of the Nippon Telegraph and Telephone Public Corporation, by setting the automatic answering mode only with a call signal of an ON- time set sufficiently longer than usual case. CONSTITUTION:Timers 25-54 check if a call tone input is consecutive for 0.3sec. The presence of the call tone within 5sec in the past is checked, and when there exists no input, it is discriminated as the 1st call tone, and an output of the timer 54 triggers a timer 55. If the measuring time of the timer 55 is elapsed for 55sec is checked from the output of a latch 56. It is detected that 5sec are elapsed after the call tone is lost by the timer 53, an output of an AND gate 59 goes to H level, and an output of an automatic answering mode setter 67 goes to H level. The presence in the lag of a cassette is discriminated already, the tape is rewound up to the tape top and the operation in the automatic answering mode is started.

Description

[Detailed description of the invention] ``,,Industrial application field''.

This invention can be used to respond to a call, receive an incoming call, receive a call, or receive a call.
The present invention relates to an answering machine configured to send a prerecorded response message. ,.

``Background technology and its problems''.

When the answering machine receives an incoming call from the 1st station line when it is in the trading mode, waiting mode, or in the standby mode, the answering machine sends an answering (oujgoing), message, ji (hereinafter referred to as oujgoing) message. , OC+M) is played back and sent to the caller. In this case, some devices are capable of recording an in''coming message (hereinafter abbreviated as ICM) from one caller after sending ': o, GM.

However, there are cases where the user forgets to set the away mode and goes out. Therefore, it is desirable that the user of the answering machine be able to set the answering machine to answering mode from outside. If the user forgets to set the answering machine, the answering machine and telephone line will normally not be connected.

Therefore, a configuration has been proposed in which the arrival of a calling signal is detected, the call is set to an incoming state within 1.0 seconds, and the answering mode is thereby automatically set. but.

With this method, the answering mode can be easily set even by a call signal from a person other than the user of the answering machine. As a result, problems such as the user's away mode being set against the user's will or o'GM with inappropriate content occurring occur. If the time is long, for example, one idea is to set the away mode in response to only those with an on time of 1 minute or more. However, 1. , Japan's telecommunications and public corporation standard specifications require that answering machines be placed in a ringing state within 10 seconds from the start of a ringing, and as mentioned above, the ringing signal has a fairly long on-time. What you need is
It violates standard specifications.

``Object of the Invention'' This invention allows the user to set the away mode via an outside line. - Realization of an answering machine that prevents the answering mode from being set by someone else's call without the L-user's will, and that also satisfies the standard specifications regarding answering time. 6 ``Summary of the Invention'' This invention provides an answering machine having an answering mode operating state in which a call is received and a pre-recorded response message is sent out from 1 when a normal ringing signal is turned on. By detecting a call signal with a sufficiently long on time, and when the off time of the detected ring signal reaches a predetermined period of time, the detected call signal or end is detected, and the end is detected. automatically sets the away mode.

−□′ (Example) □ Below, a practical example of this invention will be explained.
This invention is applied to an answering machine previously proposed by the applicant. The power-saving/accommodating device that we proposed earlier uses one magnetic tape, records the OGM only in the first part of the track of this magnetic tape, and plays this OGM every time there is an incoming call. ,O(
) After the recording □ section of M, xC'M7' can be recorded sequentially.

In Figure 1 the electrical gates of this embodiment are shown.

1 □ indicates a magnetic tape stored in a compact male compartment.Although not shown in the figure, the tape 1 is illustrated by a capstan and a pinch a-9. It runs at a constant speed of 2.4 am/s and at high speed by a reel motor. A recording/reproducing head 2 and an erasing head 3 provided on a head substrate are brought into contact with a magnetic tape 1. 4 is a bias oscillator. Further, 5 indicates, for example, a built-in microphone, 6 indicates a speaker, and 7 indicates an earphone jack. The output of the microphone 5 is supplied to the recording/reproducing head 2 via a microphone amplifier 8I, a recording amplifier 9, and a bias trap 10, and is recorded on the magnetic tape 1. At the same time, the output of the recording amplifier 9 is supplied to the speaker 6 via the volume control volume 11 and the power amplifier 12, thereby enabling recording monitoring.

OGM can be recorded on the magnetic tape 1 by the recording system described above.

Further, the reproduction output of the recording/reproducing head 2 is transmitted to a preamplifier 13, a bypass filter 14. The signal is supplied to the speaker 6 via an equalizer amplifier 15, a volume 11, and a power amplifier 12. Through this playback system, you can listen to recorded OGM tests and ICM.

Reference numeral 16 indicates a cue oscillator that generates a cue signal of 1, for example, 30 Hz, and 17 indicates an alarm oscillator that generates an alarm signal of 1 to 2 kHz, for example.

The cue signal is recorded on the magnetic tape 1 together with O()M in the OGM recording section. Therefore, a cue signal is supplied to the recording/reproducing head 2. Furthermore, when the reproduced cue signal appearing at the output of the 1 blower amplifier 13 is removed by the bypass filter 14, it is also supplied to the 2 □ detection circuit 1B, where it is converted into a detection pulse corresponding to the cue signal □. The alarm signal serves as a beep tone to the caller, and is recorded for a predetermined period of time, for example, 3 seconds, behind the recorded ICM, and further serves as an alarm to the user. For this reason, the alarm amplifier ILI
? The alarm signal generated by
The □ output is supplied to the speaker 6 via the power amplifier 12.

Terminals 23a+ 23b of telephone 22 and line terminal 24
A disconnector 25 is connected to 'a + '24b, and a parallel circuit of a contact 21 of a relay 26 and a fundensor 28 is inserted between this disconnector 25 and the other side of the line transformer 20. When a call is received, the ring tone is detected by the tone detection circuit 29, and the relay 26 contacts 27 are turned on by two rings, for example, to complete the connection with the first line. When the ICM is in the away mode,

It is sequentially determined whether or not the rewind button, 00M recording button, and absentee mode button are turned on.

When the fast forward button is turned on, a fast forward operation is performed,
The fast-forward operation is stopped by turning on the forward button, rewind button, and stop button. Also, when the 9th rewind button is turned on.

When the rewind operation is performed and the forward button, fast forward button, and stop button are turned on, the one rewind operation is stopped.

For ease of understanding, the 00M recording mode, which is performed when the 00M recording button is pressed, will be explained first. 0
When the 0M record button is turned on.

The presence or absence of lugs on the cassette can be checked. Lag detection circuit 48
When the absence of lag is detected by the output of
is supplied, an intermittent alarm sound is generated, and the mechanism is stopped.

The absence of a lag means that no tape cassette is installed, or that the lag of the installed tape cassette is stretched out, making it impossible to record.

As shown in FIG. 3, the magnetic tape 1 has a leader tape of approximately constant length connected at the beginning.

If there is a lag in the cassette, the magnetic tape 1 is automatically rewound to the top of the tape, and then a fast forward operation is performed. This fast-forward operation is performed until the count value N1 of the glue counter 47 is reached slightly before the end of the leader tape, as shown in FIG. 3B. Next, a loss forward operation (meaning a recording operation of no-signal input) is performed in the interval (Nl to Ntora) of the reel count value, and a no-signal interval 49 is formed. Further, an alarm signal from the alarm oscillator 17 is generated as a beep tone for 2 seconds, and the machine enters a pause state. At this point, one light emitting diode 43a emits light and enters a ready state.

Next, when the 00M recording button is pressed again, the first light emitting diode 43a goes out and the OGM recording operation is performed. The OGM prepared in advance is read by approaching the built-in microphone 5 and the OGM is recorded. In this case, the cue signal from the cue oscillator 16 is also recorded at the same time, and the 9 light emitting diode 43a flashes during recording. When the OGM recording is finished, the 00M recording button is pressed again, which causes a 1 second erase forward. An action is taken and then the mechanism is stopped. Also, O.G.
M is capable of recording for 60 seconds, and if it exceeds 60 seconds, it shifts to erase forward operation and then the mechanism stops. With this kind of OGM recording operation,
As shown in Figure 3B, from N2 of the reel count value to N
Both the OGM and the cue signal are recorded in the section up to , and a recording pattern is formed in which there is a no-signal section 50 after the reel count value N. In reality, since the occurrence of OGM is delayed somewhat, (N.

This is a recording pattern in which only the cue signal exists in the interval (Ns) to Ns, and only the cue signal exists in the interval (N4 to N6) after the end of QGM.

Next, the operation of the away mode in which the away mode button is turned on will be described with reference to FIGS. 3 and 5. When the Away Mode button is turned on.

The light emitting diode 43b lights up. The presence or absence of lag in the cassette is checked, and if there is no lag, an alarm sound is generated and the cassette is stopped. If there is a lag, O()M confirmation playback is automatically performed. In other words.

As shown in FIG.
After the fast forward operation is performed to 1, the confirmation playback operation starts. At this time, the cue detection circuit 18 and the CPU 32 watch whether or not the cue signal is played back, and when the cue signal is played back with the reel count value N, this count value is stored in the memory of the CPU 32 as the position of the OGM knob. Note tj1N is written. If 10 seconds pass without the cue signal being played, it will be determined that the OGM has not been recorded or is not a regular recording pattern, and an alarm will be activated ◇ The played OGM can be heard from the speaker 6 ◇ Cue How long has the signal been detected?

When the confirmation playback operation is performed and there is no signal, 3
The second lover's word operation is performed, and the no-signal section 51
(Figure 3C) is completed. The reel count value N6 of this gate is IC! M) Set the position of the knob and store it in the memory of CpTj32. Next, 'OGM) position N of the knob!
A reversing operation is performed. In this example, 19 ICs
It is possible to record up to M, and it can be checked whether the count value of ICM0M caranji is 19 or not. If this is 1
If it is 9, the mechanism is in a stopped state. Similarly, it is checked whether the cancel button was turned on,
If this is on, the mechanism will be in a stopped state. □Again. The aforementioned O()
If you wish to perform confirmation playback of OGM during the M recording mode, you can turn on the absent mode button, perform the same operation as described above, and then turn on the cancel button.

When an incoming call is received in the incoming call standby state of the absent mode, the tone detection circuit 29 supplies a detection signal corresponding to the ringing tone to the CPU 32. If this ringing tone continues for 0.3 seconds, a waiting time of 5 seconds is set. 91 Next, it is checked whether the ringing tone arrives again within 5 seconds. Bell again within 5 seconds! , when I arrived, I bought a rag for $1,000! If I hit my instep, I get 2, i! Since T occurs for 1 second with a blank time of 2 seconds, a time of 5 seconds is set. is closed and connection with the 9th line is made.

．． Second time, <7) I went to one of the I C'M recordings as well! 1
The "FLOW" operation is performed until the stored count value N6 is reached, and the recording of IC'M is started from N6.

If this is not the first 10M recording, the ICM-recording state will change to □ after the last recording.

The caller speaks the ICM after hearing the beep tone, which is supplied to the recording amplifier 9 via the line input circuit 21 and recorded on the magnetic tape 1.

The third diagram shows the recording pattern when the first ICM was recorded in this example.

The recording time for engineering commercials is stipulated to be 30 seconds.

After 30 seconds have elapsed, the reel count value N is stored in the memory of the CPU 32 as the top position of the last ICM recording section.Next, the alarm signal from the alarm oscillator 17 is sent to the caller as a beep tone for 3 seconds. It is also recorded on the magnetic tape 1. In the third diagram s

After the recording of the OICM flashing is completed, the tape is rewound to the top, and the tape enters the incoming call standby state in the same way as when the above-mentioned answering mode was set. Further, when the recording of the first ICMs is completed, the count value of the 10M counter 45 becomes 1. Next, when a call arrives again, the ringtone detection 1

By being provided earlier, among the already recorded three-second beep tones, the one in the section (N, y to Ns) corresponding to the interval of one car bed remains without being erased. .

Then, after finishing recording the second I CM t,
As in the case of recording M', a beep tone is recorded in the interval (N11 to Nio,). This ICM.

After the end of the recording/sound, the tape is rewound once to the top of the tape, then fast-forwarded to the first position of OGM, N2, and stopped at position N, and is again in the waiting state for incoming calls.
At the same time, the display on the +X CM counter 45 becomes 2, and the contact 2T turns off.

A maximum of 19 is possible. As is clear from the recording pattern in FIG. 3F, the beep tones interposed between the two ICMs last for 1 second, whereas the beep tones recorded after the last commercial CM last for 3 seconds. Therefore, when playing back a recorded ICM later, the last ICM can be easily known by the length of this beep tone.

Further, the operation when the forward button is turned on will be explained with reference to FIG. 4. When the forward button is turned on, it is checked once whether confirmation playback of 0()'M has been performed. If not, the tape will be rewound to the top.

Next, a fast-forward operation is performed up to the linyl count value N1, and O'GM confirmation playback is performed. Similar to the confirmation playback of the OGM in the absence mode described above, the playback of the cue signal is watched, and when the cue and signal are played back, this count value is stored as the position of the OGM knob.

If 10 seconds pass without the cue signal being played back, an alarm state occurs.

This is done until the stop button is turned on.

Even if none of the following buttons are turned on: , boar, 7 oward button, fast forward button, 1 rewind button, C10M recording button, and 1/2 away button, if there is lag on the cassette,
Away mode can be set. .

This setting of the absence mode from the outside will be explained with reference to FIGS. 5 and 6. Of the CPU32, this is the outside or the police station! FIG. 6 shows the section related to mode settings as a block diagram of Kudoware. In FIG. 6, 52,53°54.55 indicates a timer,
56 indicates a latch. These timers 52 to 55 and latch 56 are actually C! It is configured using the memory of the PU32. When the falling edge of the output signal of the F-tone detection circuit 29 (occurs when a ringing tone is generated) is supplied to the timer 52, the timer 52 starts counting. Then, when a set time elapses, for example 0.4 seconds, an H (high) level output signal is generated and supplied to the OR gates 57 and 58. Furthermore, when the timer 52 starts measuring, the timer 53 is reset and the timer 54 is triggered. After 4 seconds have elapsed, an H level output is generated and this is ORed.
Supplied to gate 57. Furthermore, the timer 52 is reset at the same time as the timer 53 starts measuring. timer 52
is a tone detection circuit 29 obtained by waveform shaping the ringtone.
The timer 53 measures the L (low) level of the output signal, and the timer 53 measures this H level. Along with this, the timer 53
The second set time e.g. 5 seconds after the ringtone disappears.
After a second has elapsed, an output signal that becomes H level is generated and supplied to the OR gate 57 and the AND gate 59.

The timer 54 measures the on-time of the ringer:
It is triggered by the output signal of the timer 52 and reset by the output of the 7'OR gate 5γ.

When the set time elapses, for example, 0.3 seconds, an output of level 2 is generated, which triggers the timer 55. The timer 55 is reset by the rising edge of the output of the OR gate 5B, and when a set time of, for example, 55 seconds has elapsed since being triggered, an output signal of H level is generated. The output signal of this timer 55 is the latch 56
supplied to This lunch 5th day is reset by the output of the OR gate 60.

Further, 61 indicates a memory for storing that OGM recording has been performed, and H level data indicating that QC)M recording has been performed is supplied to OR gate 63. 62

・To explain the operation of the hardware shown in Section 6- above, referring to Figure 5, first, the presence or absence of the cassette is detected, and the lag, If there is.

Memory 6.1. 1. By output and memory, 62 force output. ．． It is checked whether the 00M recording has been completed or whether the confirmation playback has been completed.If one of the recordings has been completed, the output signal of the OR gate 6B becomes ``Revo''.

Also, it is checked whether the input of the ring tone continues for 0.3 seconds. This is detected by the timer 52.53.54. Then, you can check if there is a call, an outgoing sound, or a takadori within 5 seconds. If no ringtone is input within 5 seconds, it is determined that it is the first ringtone, and the timer 5
5 is not reset.

The output of timer 54 triggers timer 55. This is controlled by the timer 5 by the output of the OR gate 5B.
5 is reset.

It is checked from the output of the latch 56 whether or not the time period measured by the timer 55 has exceeded 55 seconds. In this example,
A condition for setting the away mode is that there is a ring-on time of 55 seconds after the timer 55 is triggered. and.

5 seconds have elapsed since the ringing tone disappeared.Data Timer-5
Detected by 3. After these 5 seconds have elapsed, AND
The output of gate 59 is at the level.

The output of the absence mode setting device [67 is at Yo-level.

I've already decided whether or not the cassette has lag.

Then, the tape is rewound to the top, and from the first step, the away mode operation starts. 6 Setting the away mode from an external device does not involve connecting one line, so even if you play back the OGM for confirmation, Although the user cannot hear it, it is necessary to detect and remember the position of the top of the OGM and the position of the top of the ICM.

In addition, as in the above embodiment, by detecting the presence or absence of the cassette lug, it is possible to prevent the away mode from being set from outside when the cassette is not installed. , O()M confirmation playback is not completed, it is not possible to set the away mode from outside, so if you use a magnetic tape that does not have a regular recording pattern or the O()M does not have appropriate content.
It is possible to reduce the possibility that GM will be used.

On the other hand, after recording OGM, 0
．． The contents of October 1 are often recitations, so please take note of this.
According to this invention, even if the user forgets to set the away mode and goes out, the user can access the away mode from the outside. settings can be made. In this case, user 1 sets the away mode only when the on time is set sufficiently longer than the normal on time. ′: It's true that there is no company. However, it has the advantage that it also satisfies the standard specifications of the Telegraph and Telephone Corporation in Japan, as it detects a ringing signal with a normal on time or a longer on time, and sets the answering mode when this ends. .
