Abstract

PURPOSE:To attain practically sufficient function by allowing a digital recording means to respond to an incoming call from other line during the automatic response to the incoming call is operated. CONSTITUTION:The digital recording means 34 codes digitally a response message transmitted at the incoming state and stores it in a memory. When an incoming call to other line is detected while any of communication lines 13, 14 and 24, 25 is in incoming state, a digital reproducing means decodes a response message stored in the memory and transmits to the other line. A signal switching means leads a message from the other line to the means 34 when the transmission of the response message is finished to record it in the memory. Further, another digital reproducing means decodes the message stored in the memory and records it on a recording medium 52.

When RLIB is in a non-energized state, it is in a switched state and an on-off state as shown in the figure.

The operation of the above configuration will be explained below.

It is assumed that the movable contacts 43h, 47g, and 51a of the upper recording/re-switching switch 43, 47.degree. 51 are all connected to the recording side contact R in advance. Freezing, one communication line J
,? , I will explain the case where China and Germany arrived only on J4 (ii).

That is, when a ringing signal arrives from the communication device 1) of the previous NLr first caller via the exchange 12, the ringing signal detection circuit 18 detects the sound, activates the timer circuit 20, and activates the relay. Start energizing RLJA. The energized state of this relay RLLA is maintained for a certain period of time D until the timer circuit 20 completes its quenching operation. Then, as the relay RLIk is energized, the relay switch RIJA
-1 has its movable contact 17a connected to the second fixed contact 17c side, and the relay switch RIJA -

Therefore, the relay R is controlled by the first relay control circuit 60.

Then, when the endless chain f38 travels once and its conductive foil 39 short-circuits the pair of electrodes 40, the relay RL2A
is made energized. This relay RL? The energization state of A is determined by the energization of relay RL2A.

Erasing head 49 is brought into contact with tape 52 . Here, since the movable contact piece 51a of the upper recording/re-switch 51 is connected to the recording side contact R, the bias oscillation circuit 50 is driven and an AC bias signal is supplied to the erasing head 49.

Since relay RL2A is turned off, relay RL2A is no longer energized, the self-holding state of relay RL2A is also released, and the automatic response operation ends here.

Furthermore, the automatic response operation when a call is received solely on the other communication line 24, 25 is performed in substantially the same manner as described above. However, in this case, relay R
IJA, relay RLIB instead of RL3k,
It is easily known from the above description that RL and 9B are energized.

Above, we have explained the automatic response operation when a call is received on one of the two communication lines alone. Before explaining the operation in the case where there is, the solid state circuit 34 will be explained.

In other words, this solid-state circuit 34 uses PCM ()#Ruth code modulation) which has become popular recently.
It performs digital recording and playback using technology.

Specifically, as is already well known, an analog information signal such as an audio signal (in this case, a response message or message) supplied to the input terminal I or the input/output terminal I10 is passed through an A/D converter. The digitized data is converted into digitized data by encoding using a D/A converter and recorded in a memory, and the digitized data recorded in the memory is decoded using a D/A converter to reproduce the original analog data. The signal is converted into an information signal and output from the input/output terminal I10.

In this case, the solid state circuit 34 has its first
When the recording control terminal IR, is at a low level (hereinafter referred to as l (level)), the signal supplied to the input/output terminal I10 is digitally recorded, and when the second recording control terminal IR2 is at the H level, the input The solid-state circuit 34 digitally records the signal supplied to the terminal l.Furthermore, the solid-state circuit 34 decodes the digitized data recorded in the memory when the first reproduction control terminal IO, is at H level. Input/output terminal I10
The second reproduction control terminal IO decodes the digitized data recorded in the low level (hereinafter referred to as L level) throat memory and outputs it from the output terminal 0.

Here, after receiving a call on one communication line 13.14,
The response operation when there is an incoming call on the other communication line 24, 25 will be explained. First, the communication device 11 of the first caller
When a calling signal arrives from the caller via the exchange 12, the relays RIJA, RL, and 9A are energized as described above, the entrance tape 38 is reproduced, and a response message is sent to the first caller. At this time, since the relay switch RL4A-2 is on, the output terminal of the OR circuit O1 of the response message control circuit 59 is at H level. For this reason, solid state circuit 3
4 converts the signal supplied to its input terminal (2), that is, the response message output from the regenerative amplifier 36, into digitized data and records it in its internal memory.

-t, and when the endless Steve 38 runs one round, that is, the response message ends and the relay RL2k is energized, the relay switch RL2A-3 is turned on and the control signal oscillation circuit 42 is driven. This control signal oscillation circuit 42 is composed of, for example, a one-shot multivibrator circuit, and includes relay switches RL, ? A
-3 is in the on state, it outputs a control signal at H level for a predetermined period of time. This control signal is then recorded in the solid state circuit 34 as a signal indicating the end of the response message.

Thus, after the response message has been sent to the first caller and recorded in the solid-state circuit 34, the first
The message from the caller will be recorded on tape 52 as described above.

And this first caller's messenger is Chi 7'5. ? Assume that a calling signal arrives from the second caller's communication device 22 via the exchange 23 while the second caller is recording. Then,
Relay RLIB is energized and relay switch RLI
B-2 is turned on. By the way, at this time, as mentioned above, since the first relay control circuit 6Q first energizes and drives the relays RL and 9A, the second relay control circuit 61 does not energize and drive the relay RIJB.
Relay switch RL3B-1, RL3B-2, RL3B
-3 remains in the state shown in FIG.

Here, the two input terminals of the answer message control circuit 59 are connected to A as shown in FIG.

B and the output terminal of the AND circuit A2 is C, the input/output relationship of this response message control circuit 590 is as shown in the following table.

As is clear from this table, the output terminal C of the AND circuit A2
becomes H level only when both A and B become H level. Therefore, as described above, when the relay switch RIJB-2 is turned on, the output terminal C of the AND circuit A2 is at the it level, and the solid state circuit 34 decodes the response message recorded in the memory. and outputs it from its input/output terminal I10. The response message output from this solid state circuit 34 is relay switch RL, 9B-1, line transformer 30, relay switch f RLIB-1, terminal 26.2.
7. It is sent to the second caller via the communication lines 24 and 25, the exchange 23 and the communication device 22.

When the sending of the response message from the solid state circuit 34 is completed and the control signal is output from the input/output terminal I10, this control signal is sent to the control signal detection circuit 35.
Detected in Then, the control signal detection circuit 35 outputs an H level detection signal to the first recording control terminal IR1 of the solid state circuit 34. Therefore, the solid state circuit 34 transmits the message from the second caller to the communication device 22, the exchange 23, and the communication circuit +ili! , 94.

25, terminal 26.27, relay switch RLIB-1,
The data is converted into digitized data and recorded in a memory via the line transformer 30, relay switch RLJB-1, and input/output terminal I10.

Therefore, the message from the first caller will be recorded on tape 52 and the message from the second caller will be simultaneously recorded in the memory of solid state circuit 34.

In this state, when the timer operation of the timer circuit 20 ends, the relay RIJA is de-energized and the relay switch RLIA-2 is turned off, as described above. Here, as explained earlier, if there is an incoming call on only one communication line (for example, 13°14), when the relay switch RLIA-2 is turned off, the first relay control Circuit 6o is relay RLJ
A is operated to de-energize, but when the solid-state circuit 34 is performing a recording/reproducing operation,
First relay control circuit 6o beam race isochi RLIk
Even if -2 is in the off state, relay RL, ? It operates to keep A in a energized state. And at this time, the second

, 9A-3 are kept on, so the motor 54
The plunger coil PL2 continues to be energized, and the tape 52 continues to run.

At this time, the first relay control circuit 60 controls the relay RL3.
A is being energized, the solid-state circuit 34 is recording the message from the second caller, and the relay switch RLIk-2 is turned off. Therefore, the detection circuit 63 detects this state of the first relay control circuit 60 and transmits the L level detection signal to the second regeneration control terminal I02 of the solid state circuit 34.
Output to. Then, the solid-state circuit 34 sequentially decodes the message from the second caller that was previously recorded (and is still being recorded) starting from the beginning recorded in the memory, and outputs the message from the second caller. 0 to the preamplifier 440 input terminal. Therefore, the message from the second caller is
After the first caller's message is recorded on the tape 52, the first caller's message is recorded.

That is, functionally speaking, the detection circuit 63 detects the end of the operation of the timer circuit 20, that is, the first caller's tape 5.
Detect when recording to 2 ends.

In this detection state, messages from the second caller are sequentially output from the solid state circuit 34 and recorded onto the tape 52.

In this case, the solid-state circuit 34 simultaneously performs the operations of recording the second caller's message in the memory and outputting the message from the beginning recorded in the memory.

In this state, when the timer operation of the timer circuit 3 is completed, the relay RIJB is de-energized.

In this case, the first relay control circuit 60 is the relay RL 3
The power supply continues to be applied to the Qi 7'52 so that the Qi 7'52 does not stop running. Then, all of the second caller's message recorded in the solid state circuit 35 is transferred to the tape 5.
2 and when the playback operation of the solid state circuit 34 is completed, the first relay control circuit 6o switches to the relay RL.
,? A is brought into a non-energized state, all operations are completed, and the state returns to the original standby state.

1. The operation when there is an incoming call first on the communication line 24.25 and then on the communication line 13.14 can be explained in almost the same way as the above explanation, so the explanation is as follows. Omitted.

Furthermore, in the above explanation, a case has been described in which there is an incoming call on the communication line JJ, 14, and after all the response messages are recorded in the solid state circuit 34, there is an incoming call on the communication line 24.25. is the communication line 24 while the solid state circuit 34 is recording the response message.
．． If there is an incoming call on 25, 51 will operate in the same manner. In this case, the solid-state circuit 34 records the response message in the memory, and sequentially records the response message recorded in the memory in two parts, starting from the beginning.
The message will be sent to the sender.

Therefore, according to the configuration of the above embodiment, when a call is received on both communication lines 13.14 and 24.25, automatic answering is performed simultaneously on both communication lines 13.14 and 24.25. The first
Messages from the second caller and the second caller can be recorded on the same Qi 7''52, which is extremely practical.

The present invention can also be widely applied to, for example, between men's baths during construction work, between multiple dams and their centralized monitoring stations, to centralized traffic information monitoring stations for multiple areas, or to general answering machines. .

Here, FIG. 2 shows details of the first and second relay control circuits 60, 61.

That is, to explain the operation according to the above-mentioned explanation, first, the communication line 13.14 enters the incoming state, and relay R is activated.
LJA is energized and relay switch RL4A-2
Suppose that it is turned on. Then, the AND circuit Aar
The output of the matching circuit 64m consisting of the NOR circuit N0al and the OR circuit Oal is inverted from the H level to the L level. Further, the output of the NOT circuit Nal is also inverted from the H level to the L level, and the output of the NAND circuit NA a 1 is at the H level. At this time, the output of OR circuit Oa2 is H
level.

And NAND circuit NAa2. The output terminal of the flip-flop circuit 65a (NAas) becomes H level. Here, the NOT circuit Na2 and the NAND circuits NAa4 to N
Aa7 constitutes a latch circuit 66t, and this latch circuit 66a latches the output signal of the flip-flop circuit 65m when the output signal of the OR circuit Oaz (hereinafter referred to as 5TRB signal) is at H level. It works like this. Therefore, the output terminal Q of the latch circuit 16h is high.
level. On the other hand, at this time, the second relay control circuit 6
Since the output terminal Q of the latch circuit 66b of No. 1 is at the L level, the output of the NOT circuit Na3 is not at the H level, and eventually the output of the AND circuit Aa2 is at the H level. Therefore, the output terminal Q of the set-reset fly-lag flop circuit (hereinafter referred to as S-RFP circuit) 67a is at H level, and the transistor Qa is turned on, so that the relays RL and 9A are energized and driven. It is something.

In this state, communication lines 24 and 25 enter the incoming call state, relay RLIB is energized, and relay switch R is activated.
Assume that LJB-2 is turned on. Then, the output terminal Q of the latch circuit 66b of the second relay control circuit 61 becomes H.
However, since the output terminal Q of the latch circuit 66& is at the H level, the output of the NOT circuit Nb3 is at the L level.
The output of the AND circuit Ab2 is set to the L level, and the relay RL, ? B is not driven with electricity.

Then, the timer operation of the timer circuit 20 ends,
Even if the relay switch RLJtA-2 is turned off, the output terminal Q of the 5-RFP circuit 67m remains at the H level, so the relay RL3A is energized and driven.

Thereafter, when the solid state circuit 34 sends all messages from the second caller to the chip 52, the solid state circuit 34 generates an H level reset signal at the input terminal 68. Therefore, the output terminal of the 5-RFF circuit 67h is inverted to the L level, the relay RL3k is de-energized, and the above-described automatic response operation is all completed.

It goes without saying that the operation when the relay switch RLIB-2 is first turned off and then the relay switch RLJA-2 is turned on can be explained in substantially the same manner as above.

Note that if the input terminal of the latch circuit 66h is D (see FIG. 2) and the inverted output terminal is Q, the signal relationship between the 5TRB signal, the input terminal, the output terminal Q2, and the inverted output terminal Q is as follows.
The result will be as shown in the figure.

That is, the signal at the input end is latched when the 5TRB signal is at the H level, and the latched state is maintained while the 5TRB signal is at the L level.

Next, FIG. 4 shows details of the detection circuit 63. That is, this detection circuit 63 detects the relay RLI
A, RLIk linked to RLIB
-3, RLJB -3,5-RFP circuit 69m, 6
9b and OR circuit 03, etc. and,
First, when the relay switch RIJA-2 is on and the output of the shand circuit Aa2 becomes H level, S-R
The output terminal Q of the FF circuit 69a becomes I (level).
The level signal is supplied to the second reproduction control terminal IO2 of the solid state circuit 34 via the OR circuit 03 and the output terminal 70. At this time, since relay RLJA is energized, relay switch RLJA-3 is switched to the position shown in FIG. 4.

Then, when the relay switch RLIB-2 is turned on, the output terminal Q of the latch circuit 66b goes to the H level, and the output of the Synnott circuit Nas goes to the L level, so the output of the AND circuit Aa2 goes to the L level, but S -The output terminal Q of the RFF circuit 69a is held at H level.

In this state, when the timer operation of the timer circuit 20 is completed and the relay RL4A is de-energized, the relay switch RIJA-3 is returned to the on state, and the 5
-The output terminal Q of the RFP circuit 69m becomes L level. The solid state circuit 34 is therefore responsible for transmitting the recorded message to the tape 52.

The operation of this detection circuit 63 is also controlled by relay switch RL.
Of course, the same explanation can be applied to the case where 7B-2 is turned on first.

Note that the present invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications without departing from the gist thereof.
