Abstract

PURPOSE:To eliminate complaint about wrong dial by sending a voice signal informing that the relevant terminal is a facsimile equipment when a voice signal detector detects the voice signal. CONSTITUTION:When a called party replies a call in voice by using a telephone set, a caller receives the signal through a control circuit S7 and a filter S11. A voice signal detector S12 detects the voice signal through the filter S11 to throw a CML-SWS (equipment connecting switch) 3 to the position 'a'. Moreover, the other output of the voice signal detector S12 is fed to a voice generator S13, which is driven and the voice signal such as 'Hallow, this is the Facsimile equipment' is sent to the called party via a switch S15 and the CML-SWS3, and after the voice is sent for a prescribed time, all functions are reset and the initial state is restored. Thus, the complaint such as wrong dial is eliminated.

A control circuit S8.8 of the facsimile machine connected to the b'' side of R3 is an image information processing section of the facsimile machine connected to the control circuit S7.7.

Next, the operation will be explained. Here, FIG. 9 is an explanatory diagram showing the exchange of information in the case of normal transmission in which the sending side dials using the automatic dialing device SO and sends image information, and FIG. FIG. 6 is an explanatory diagram showing the exchange of information in the case of polling reception in which a dialing device 0 is used to make a dial call and receive image information.

First, the case of normal transmission will be explained. Assume that each switch is now in the state shown in FIG. first,
Set the destination dial number on the automatic dialing device SO,
When you press the start button S2, a dial signal is sent to telephone line 1, and then CML-8WS3 automatically starts “
CM L-S W 83 is switched to "b" side and connected to the control circuit S7, and the above-mentioned automatic dialing device SO and telephone S1 are also disconnected from the telephone line 1. At the same time, CM L -S W 83 is switched to "b". A signal indicating this (hereinafter referred to as a CML-ON signal) is supplied to the control circuit S7, and the control circuit S7 is now on standby in a control signal receiving state.

On the other hand, the called side (receiving side) receives the CI from the exchange through the telephone line 1 in response to the dial signal described above. Now, as shown in Figure 8, CML-8W 3, automatic/
When the manual ring switches R+4 are each connected to the "a" side, CI is supplied to the CI detector R5 and the telephone set 1. Even if telephone R1 is hooked down, CI detector R5 detects CI and sends a signal indicating that CI has been detected (hereinafter referred to as CI detection signal) to automatic/manual incoming call switch R4.
The CML-8Wa3 is supplied to the CML-8W 3 through the CML-8Wa3, the CML-8Wa3 is switched to the b'' side, and the control circuit Rγ is connected to the telephone line 1.The CML-8Wa3 supplies the CML-ON signal to the control circuit 7, The control circuit 7 is placed in a control signal transmission state.

When the control circuit ratio 7 enters the transmitting state, the called side (receiving side) first transmits the called station identification signal (hereinafter referred to as CED) to the control circuit ratio 7 as shown in FIG. 9(a). 8W 3. The signal is sent to the calling side (sending side) through the telephone line 1, and then a digital identification signal (hereinafter referred to as DIS) is sent, after which the control circuit 7 waits in a receiving state.

On the calling side (sending side), telephone line 1. CML-8"v'V
CHD is received by the control circuit S7 through "b" of S3, and after receiving this CED, D1.
S is received. In response to this signal, the control circuit S7 internally performs necessary actions, then enters a transmission state and sends out a digital command signal (hereinafter referred to as DO8) and then a training check signal (hereinafter referred to as TCP). In response, the called side (received side) confirms reception preparation (hereinafter referred to as
When the CFR is returned, the calling party (sender)
starts transmitting image information (PIX).

In addition, in the case of polling reception, as shown in Figure 1O (a), set the dial number of the automatic dialing device ROK in the same manner as described above, press the start button 2, the dial signal is sent to the telephone line 1, and then the CML -swa3 is b”
When switching to υ, CED and DIS are sent from the control circuit S7 on the called side (sending side) in the same way as in the case of normal transmission (however, in this case, the calling side becomes the receiving side and the called side becomes the sending side). Ru. Control circuit 7 on the calling side (receiving side) that received the DIS
sends out a digital transmission command (hereinafter referred to as DTC), and then enters a reception state and waits.

Next, the called side (sending side) that received the DTC sequentially sends DO8, 'TCP as in the case of normal transmission.
By returning the CFR from the calling side (receiving side), image information (FIX) can be received.

The above is a case where signals are exchanged normally,
For example, in the case of normal transmission, if the calling side (sending side)
When DC8 cannot be received normally, DC8 is not sent, and the called side (receiving side) sends DIS again because DC8 is not returned, and DC8 is sent within the specified time.
DIS is sent out repeatedly until it is returned. FIG. 9(b) shows this situation using an example in which the calling party makes a call using a telephone.

Also, if the called side (receiving side)
, DIS are not sent, the calling side (sending side) remains unresponsive for a predetermined period of time and continues to wait for CED and DIS signals. This situation is shown in FIG. 9(C).

The same is true for polling reception, as shown in Figure 10 (Cl,
The situation is shown in (b).

Note that in the present invention, the image information processing section S8.几8, and FIX
Since the process after sending is not particularly relevant to the present invention, a description thereof will be omitted.

In addition, the automatic/manual incoming call switch 84, R4 is always set to the "a" side in this explanation, that is, when it is set to automatic incoming calls, and is not particularly relevant for manual incoming calls (on the opposite side from FIG. 8). The explanation will also be omitted.

[Problem that the invention seeks to solve]

Conventional facsimile communication control systems are set up as described above, so if a dial number is entered into an automatic dialing device incorrectly and a connection is made by dialing to a home telephone, etc., there will be no response), DCN (line disconnection command)
2) If you accidentally call a place where a fax machine is connected,
C.H.D.

DIS, DIS... I can hear the sound of B-gear as the DIS repeats. Not only is this situation incomprehensible to both the person receiving the call and the person making the call, but when the power is turned off, it can cause mental distress, especially for the person being called.Recently, this problem has begun to be taken up as a social problem in some quarters. There was a point.

This invention was made to solve such problems, and it improves communication with facsimile machines that have conventional communication control methods to relieve the mental pain caused by the pinging noise caused by a wrong call or a long period of silence. The objective is to obtain a facsimile communication control method that can be achieved at low cost without any problems.

[Means for solving problems]

The facsimile communication control system according to the present invention includes a filter that blocks passage of a control signal and passes part or all of an audio signal other than the frequency band of the control signal,
When the audio signal detector detects the audio signal that has passed through this filter, it activates the audio generator and sends an audio signal to the telephone line informing that the terminal is a facsimile machine. In the facsimile communication control system according to another invention, when the audio signal detector detects an audio signal that has passed through a filter, the audio signal detection display displays that the audio signal has been received, and further includes: In the facsimile communication control system according to still another aspect of the present invention, when the voice signal detector detects the voice signal that has passed the filter, the voice generator is activated and the terminal is connected to the telephone line as a facsimile device. It sends out an audio signal to notify the user that the audio signal has been received, and also uses an audio signal detection indicator to display that the audio signal has been received.

[For production]

The facsimile communication control method according to the present invention utilizes the fact that the control signal occupies only a limited frequency band of the voice signal to detect the signal that has passed through a filter that blocks the passage of the control signal. The voice generator automatically sends a voice signal to the other party's terminal via the telephone line indicating that it is a facsimile terminal, and also, In another aspect of the present invention, the voice signal detection display displays that the other party's terminal is a regular telephone or the like to warn the user to respond by voice over the telephone, and in yet another aspect of the present invention, It displays on the voice signal detection display that the other party's terminal is a normal telephone or the like, and also sends an audio signal to the other party's terminal indicating that this is a facsimile terminal.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, 1.80 to S8 and 0 to R8 are the same as or equivalent to the conventional one denoted by the same reference numerals in FIG. 7, so their explanation will be omitted.

Also, S11.几11 is CML-8WS 3 or R

Next, the operation will be explained. Here, FIGS. 2 and 4 are explanatory diagrams showing the exchange of information during normal transmission, and FIGS. 3 and 5 are explanatory diagrams showing the exchange of information during polling reception. First, the case of normal transmission will be explained assuming that each switch is initially in the position shown in FIG. When the sender makes a call using the automatic dialing device SO in the same way as before, a dial signal is sent to telephone line 1, and CML-8WS 3 is automatically dialed.
"b" of this CML-8WS3.
The side is connected to the control circuit S7 and the filter Sit. On the other hand, the called side (receiving side) also detects CI as in the conventional case, the CML-8W switch 3 is turned on to the "b" side, and the control circuit switch 7 goes into the transmitting state. In this case as well, CM L-8W
@b'' side of R3 is the control circuit R7 and filter ft1
Connected to 1. This filter 811. R11 is
As mentioned above, the control signals CED, DIS, DC8, D
These CED and DI do not pass through TC.
S.

DC8 and DTC are audio signal detectors 812. It is not detected in R12. Further, after the control circuit S7 detects DISj or DTC (at the time of polling), the control circuit S7 detects DTC.
After detecting S12.O8, the respective audio signal detectors S12.几12
are reset, respectively, and the audio signal detectors S12.几12
are provided so that they do not perform any audio signal detection operation. Therefore, if both the calling side (sending side) and the called side (receiving side) are facsimile machines, filter S11.几11 and audio signal detector 812. CED and DIS are reset by the reset operation of R12.

DC8, TCP, CFR, image information (PIX),...
The DCN and the sequential communication two-picture information (PIX) are transmitted in the conventional manner. This also applies to polling reception. This situation is shown in FIGS. 2 and 3.

Now, for example, as shown in Figure 4(a), if the called party is a telephone, the CI will ring the stain removal machine's bell), which causes the person to pick up the handset and make a sound, for example, "moji moji". If there is a response, the calling side (sending side) will receive this signal at the control circuit S7 and filter 811. Since the control circuit S7 cannot receive the CED and DIS signals, it maintains a reception standby state. On the other hand, the filter 811 is C
ED.

Since both the DIS and the DIS receive wide band audio signals (see FIG. 6), audio signals outside the CBD and DISCD bands are passed through and supplied to the audio signal detector 812. Audio signal detector 812 detects the audio signal that has passed through filter 811. Audio signal detector 812 that detected this audio signal
One of the outputs of is supplied to CML-8WS3,
Insert 8WS3 into "a" side. At this time, the design is such that the '1 talk line remains closed. Also,
The other side of the audio signal detector 812 output is the audio generator 81
3, and drives this to send an audio signal, for example, "Moshi Moshi Kotilano Facsimile" to switch 8 i 5.
, CML-8WS 3 to the called party, and after transmitting voice for a certain period of time, all functions are reset and returned to the initial state.

On the other hand, as shown in Fig. 4(b), if the calling party is a telephone and the called party is a facsimile, the called party (receiving party) detects the CI and the CML-8W 3 is sent to the "b" side. The control circuit 7 sends out CED and DIS. On the other hand, the calling party who made the call somehow learns that the called party has connected to the line and makes a "mojimoji" sound.

At this time, a beeping sound can be heard on the υ-instant handset due to the CED and DIS, but the following voice response is immediately returned. That is, the voice signal that the calling party says is "mojimoji" is transmitted to the called party (receiving party), is detected by the low voice signal detector R12 in the filter 11 as described above, and is sent to the CML-8W 3. The output signal is input to the "a" side, and a voice with a voice generation rate of 13 is sent out through the switch R, l5 and the CML-8WR3. After sending out data for a certain period of time, all functions are reset and returned to their initial state.

Note that the switch 815. R15 is a sound generator S
13.几13 and speaker 814. It switches R14, and if it is placed on the opposite side as shown in the figure, that is, on the speaker side, you can hear a voice saying "Moshi Moshi" from this speaker S14°. If you listen to this and make a 7-up call on telephone S1 or phone 1, you will be able to answer the call.

The picture information processing units sB and R8 are parts that process picture information (PIX) and are not particularly related to the present invention, so a description thereof will be omitted.

Further, the same applies to the case of polling reception, and the situation is shown in FIGS. 3 and 5.

The operation in this case is also performed in exactly the same manner as described above, and a special explanation will be omitted.

In addition, in the above embodiment, an example is shown that has both a function of automatically responding by voice using a voice generator and a function of warning to respond by speaking through a speaker, but it is possible to use only one of the functions. It is very good to have a speaker as an audio signal detection indicator, and if it can warn you of a telephone response in some way, it can be used as a text display,
It can be replaced with a lamp display, a buzzer display, etc., and the sound generator may be any device that mechanically or electrically generates a sound that informs the calling or called party that the terminal is a facsimile. Tape recorders, floppy disks, memory, etc. are used.

In addition, in the above embodiment, a band rejection type filter was shown as the filter, but for example, as shown in FIG. 7(a),
Even if it is a low-pass filter that has a cutoff frequency just below the control signal, or a band-pass filter that passes audio signals in a frequency band lower than the control signal as shown in (b), (C Even if it is a high-pass filter that has a cutoff frequency just above the control signal as shown in (d), it is even a band-pass filter that passes an audio signal in a higher frequency band than the control signal shown in (d). In addition, in the above embodiments, the type of control signal CBD as
, DIS, DC8, DTC, etc. have been explained, but they are not limited to these.In short, any signal that can be easily distinguished from a voice signal and is sent as soon as possible after the facsimile device is connected to the line is used. Well, for example, NCF, CIS.

It is also possible to use GI, LC8, etc., and any combination or any one of these control signals may be used. Further, in the above embodiment, DIS.

After detecting DTC and DC8, the audio signal detector is reset, but it is not limited to this signal, and any signal that is not blocked by the filter and is received immediately before being received can be replaced with these signals. .

In addition, if the audio signal detector is reset by the control signal during the period when control signals such as CHD, DIS, DC8, etc. are being sent, the audio signal detector will not operate during this period, so the output of the filter will be There is no problem even if the signal leaks, and filters are easier to design and cheaper.

Furthermore, although the above embodiment describes the case of a phone equipped with an automatic dialing device, the same applies to cases where the telephone dial is manually dialed and the start button is pressed without checking the CED on the handset. However, it is also possible to apply this to devices that do not have such an automatic dialing device, and the same effects as in the above embodiment can be obtained.

〔Effect of the invention〕

As described above, according to the present invention, when a call is made for the purpose of voice communication, even if the other party is connected to a facsimile,
Also, if you make a call to send or receive a facsimile and it is accidentally connected to a telephone, if you speak into the telephone's transmitter, the facsimile will automatically become ready for voice response. Alternatively, a warning can be issued and a response can be made by telephone, which has the effect of preventing complaints caused by erroneous calls or the like.
