Abstract

PURPOSE:To select one line for communication and for facsimile communication and to operate the line even if the automatic reception reply function remains to be set by transferring control to a facsimile communication control in the presence of the arrival of an identification signal and to the communication control in the absence of the identification signal respectively. CONSTITUTION:A detection means 3 is provided, which detects whether or not an identification signal representing a caller terminal equipment to be a non-voice terminal equipment to a called terminal equipment from a caller terminal equipment succeedingly within a preset time after the detection of a call signal. Moreover, a control means 1 is provided, which switches the connection of a facsimile circuit or a speech circuit selectively to a line 8 based on the result of detection of the detection means 3 and transfers the control to the facsimile communication control in the presence of the identification signal and to the speech control in the absence of the identification signal respectively. Thus, one line is switched to the speech and facsimile communication even during the setting of the automatic reception reply function.

Description

[Detailed Description of the Invention] [Object of Defense] (Field of Industrial Application) The present invention provides an automatic reception response Fj! that detects a calling signal from an exchange and automatically responds to the reception operation. This article relates to facsimile machines that control functions.

(Prior Art) Some of today's facsimile machines have Jj<
Therefore, for example, auto-dials often have an automatic reception/response function that allows them to automatically respond to an incoming call from a facsimile machine or the like.

Figure 4 shows this automatic reception! 5 answers! ! [This figure shows an example of a communication procedure in a conventional facsimile machine when receiving a call with the 1hi setting 1n.

(In other words, in FIG. 4, when a call No. 13 (CI) is received from the exchange in conjunction with a call from the calling terminal, the called terminal first performs control to connect the DC loop to the rfj.

Thereafter, the called terminal sends the called terminal identification signal CED (indicating that the own terminal is a non-voice terminal) to the calling terminal, and then sends a digital identification number 18 Dis (or group identification signal Gl). The non-semi-functional identification signal NSF,
It is sent together with the called terminal identification signal C3l (indicating the own terminal's telephone number).

The calling terminal receiving these 8 signals sends the digital command signal D as a response signal to the above DIs (or Gl>).
C8 (or group command signal PiGC) is not specified *Inability determination signal NSS% Calling terminal identification signal e 1” S J and b
is sent to the called terminal.

On the other hand, the called terminal finds 1) C8 (also a flea GC) in the signal received from the calling terminal, and from this point on, it starts the normal procedure.

At the start of this facsimile procedure, a training check signal TCP is first sent from the calling terminal to the called terminal.

When this training check message J''3TCP is received normally, a reception preparation confirmation signal CFR is sent back from the called terminal to the calling IrfI4i terminal.

Next, the calling terminal that has received the reception Qjffa confirmation signal CFR starts transmitting the image information Pix to the called terminal, and upon completion of the transmission, transmits a procedure end signal ``EOP''.

Thereafter, the called terminal responds to the received procedure end signal EOP by sending a message WtF? to the calling terminal. The signal MCF is returned, and the line is disconnected in response to the disconnection command signal DCN from the calling terminal to the MCF.

In such conventional facsimile machines, automatic reception response
When a call is received while the function is set, normal facsimile communication is started after exchanging control signals such as i'+rj with the calling terminal, and there are no regulations for sending these control signals. When a terminal is used as a calling terminal, it is not possible to respond to a telephone call as well as facsimile communication when receiving a call from the calling terminal.

In other words, with this type of conventional facsimile machine, when the automatic reception and response function is set, it is not possible to answer an incoming call from a voice terminal and make a 3ITJ conversation, but the automatic reception and response function is disabled. Then, each time an incoming call signal arrived, the operator of the called terminal would pick up the handset of the telephone, confirm the calling terminal, and switch the connection.

In addition, if you adopt a method that automatically monitors the line after the automatic reception response and guides the operator of the called terminal to the call, or a method that performs voice detection and calls the operator of the called terminal, etc., the automatic reception b1 function can be improved. It is possible to respond to incoming calls from a voice terminal without changing the settings, and to switch between using a single line for calls and facsimile communication, but these methods require support from a dedicated bar-do. It was essential and impractical.

(y'F, the problem that Ming is trying to solve) In this way, in the above conventional facsimile machines, if there is no hardware support to monitor the line or perform voice detection, the automatic reception response alpha function is canceled. There was a problem in that unless the system was set up in advance, one line could not be used for telephone calls and for facsimile communication.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to switch a single line for telephone calls and facsimile communication even if the automatic reception response function is set, and in this case, special hardware is required. The purpose of the present invention is to provide a facsimile device that does not require hardware support.

(Structure of the Invention) (Means for Solving the Problems) The 77-kushimi device of the present invention automatically closes a DC circuit in response to a calling signal from an exchanger and starts a receiving operation when receiving the calling signal. detection means for detecting whether or not an identification signal indicating that the calling terminal is a non-voice terminal r is received from the calling terminal to the called terminal within a predetermined fixed time after detecting the incoming call. Then, based on the detection result of the detection means, the connection of the facsimile circuit or the telephone circuit to the line is selectively switched, and if the identification signal is received, the facsimile communication υJ crime is committed, and the identification signal 9a is not received. If so, please control the call control respectively.
i11.

(Function) In the facsimile machine of the present invention, the exchange is possible! After receiving the paging signal from J1tti, the calling terminal continues to confirm that the calling terminal is a non-voice terminal and monitors the called terminal for a predetermined period of time to see if an identification signal is received. If the identification signal is received, the communication shifts to facsimile communication, and if there is no reception of the identification signal (a), a ringtone is sounded to prevent the operator of the called terminal from being called, and the response to this ringtone is After detecting an off-hook response at a call terminal, a call is announced.

(Example) Hereinafter, an example of the present defense will be explained in detail based on the attached drawings.
Explain to 11+.

FIG. 1 is a block diagram showing an embodiment of a facsimile device according to the present invention. D section 1, reading section 2, transmitting/receiving section 3, recording section 4, input section 5, notification section 6.7112 story 17
is equipped.

Of these, the transmitting/receiving section 3 that transmits and receives the image signal J3 and the control signal is composed of a signal detecting section 31 and a line controlling section 32,
In particular, the signal detection unit 31 analyzes various identification signals received from the other party's terminal, and the line system fI 11 unit 32 detects the white ! Performs J1 call processing, 4A8 calls, etc.

In the transmission operation of this facsimile machine,
The image signal obtained by reading and scanning the original in the reading section 2 is sent to the line 8 through the transmitting/receiving section 3 under the control of the main control section 1, and is transmitted to the other party's terminal.

Further, the image signal received from the other party's terminal through the line 8 is transmitted to the recording unit 4 via the transmitting/receiving unit 3 under the control of the main control unit 1.
The received original is recorded and ejected as a received original.

Input of operation start commands, etc. related to such normal transmission/reception operations can be performed from the input unit 5 by an operator's operation.

The notification section 6 is composed of a liquid crystal display, an LED, a buzzer, etc., and when a call is received from a voice terminal, it emits a ringtone or the like in order to cause the operator of the called terminal to respond to the call made by the telephone 7.

In this facsimile machine a, for example, an automatic reception response function can be set or canceled by an input operation on the input unit 5.

When you receive an incoming call with this automatic reception response ne set, you can of course respond to the facsimile call as before, but if necessary, you can also connect to the EA8 or other connection.
By switching to the a7 side, it is possible to respond to calls.

As mentioned above, while referring to the operation sequences shown in FIGS. 2 and 3, we have explained the respective controls in these two
I will explain in detail the works of IIJ.

First, Figure 2 shows a state in which the called terminal (a facsimile machine having the configuration shown in Figure 1) is set to the automatic reception response b1 function, and dialing from O1 to Dial 1 is made from the 77/Kushimi HIU as the calling terminal. This is an operation sequence when a call for facsimile communication is made by the function.

In this case, after the calling terminal sends a dial, the calling terminal sends a calling terminal identification signal CNG at 3-second intervals, indicating that the calling terminal is a non-voice terminal, and waits for a response from the called terminal. becomes.

In response to the call originating from the calling terminal, a calling signal (CI) is received from the exchange 1 to the called terminal via the line 8.

On the other hand, in the called terminal, when the signal detecting unit 31 detects the paging signal (C1) from the exchange, the line control unit 32 immediately closes the DC loop, and then continues for a certain period of time to respond to the incoming call. A transition is made to the CNG monitoring process that monitors whether or not there is a CNG signal from the call terminal.

According to the above-mentioned call conditions, the yt calling terminal at this time is a non-voice terminal (facsimile machine with auto-dial function), so if there is no problem, the CNG call will definitely arrive at the called terminal. There will be.

In the CNGF viewing mode set by the CNG monitoring process J1■, the transmitter/receiver 48 section 3 monitors whether or not there is an incoming CNG call by the signal detection section 31, and the FXC
When it detects that there is an incoming NG call, it will send a message to that effect to 1161.
Notify 1 part 1.

By this notification, the first system 611 unit 1 can recognize that the calling terminal is a non-voice terminal, and based on this recognition result, the -CNG monitoring process immediately shifts from ■ to communication processing ■.

That is, in this communication processing J11■, the main control unit 1 first sends the called terminal identification signal "3CED" (indicating that the own terminal is a non-voice terminal) to the calling terminal, and then ;Type b1 function identification Shintan NSF, called terminal identification signal C

) After sending IS, it waits for a response from the calling terminal.

Thereafter, normal facsimile procedures (corresponding to FIG. 4) are carried out between the calling terminal and the called terminal, and the called terminal receives facsimile information corresponding to the transmission from the calling terminal.

Next, FIG. 3 shows an operation sequence when a call for the purpose of conversation is made from telephone L1 as a calling terminal in a state where the automatic reception response function is set in the called terminal.

In this case, for each M call, which is the calling terminal, the operator performs a dial input operation to access the called terminal.

With this call originating from the calling terminal, a calling signal (CI) is sent from the exchange to the called terminal via line 8.

Incidentally, in conjunction with the transition to the CNG monitoring process (2), a message may be sent from the called terminal to the calling terminal to request the operator to wait for the CNG monitoring time.

Now, according to the above-mentioned call conditions, since the calling terminal at this time is a voice terminal (telephone gate), the called terminal is
It means that there is no trust in NG.

In the CNG monitoring mode set in the CNG monitoring process immediately, the signal detection unit 31 of the transmitter/receiver 3 monitors whether or not there is an incoming CNG call.
If there is no incoming call, the main control unit 1 is notified of this fact.

By this notification, the main control unit 1 can recognize that the calling terminal is a voice terminal, and based on this recognition result, the CNG monitoring process (■) starts with the ringing tone IJJ process Ml! ■Move to. 1 J3 is at the ringing sound of Uko 1ε Senjoku ■, and the main control unit 1 first issues a control 11 command to the notification unit 6! Then, a ring tone is emitted to make the operator of the called terminal answer the call.

In the same poem, the main control unit 1 sends a call 11 to the calling terminal.

When the operator of the called terminal picks up the handset of the 1Q Ij 17 to answer the above-mentioned ring tone, this state is notified to the main control unit 1 as hook-off.

In response to this hook-off notification, the bdoduki master fi 11 section 1 instructs the line fl/Jtl 11 section 32 to switch the connection with the line aIj to the telephone disconnection 7 side, and then connects J: to the operator of the calling terminal. 5I! Execute X immediately.

In this type of facsimile machine, during the setting of automatic reception 3 response function, in addition to the request to immediately perform facsimile reception 3 in response to an auto-dial call from a calling terminal, for example, 1. There is also a request to take advantage of the fact that an operator is waiting on the called terminal side and to have a telephone conversation before receiving a facsimile.

In the facsimile apparatus of the present invention, the control corresponding to the operation sequences shown in FIGS. This makes it possible to easily meet the various demands mentioned above.

〔Effect of the invention〕

As explained above, according to Akira Kibana's fatassimili device d, after detecting an incoming call on the 11f outgoing number 18 of the exchange, the calling terminal continues to communicate with the non-voice terminal from the 1111f' terminal to the destination 11f terminal. Set the mode to monitor the C- for a certain period of time to see if there is an incoming Pi CNG call, and if there is an incoming No. 4 CNG call in the monitoring mode, it will immediately receive the Pi CNG call. If the CNG does not receive an incoming call, the line will be switched to the telephone side and the call will proceed, so even if the automatic reception response function is set, one line will be used for XlrJ calls. Facsimile (c'
It has the excellent advantage of being able to switch between different types of applications, and providing a variety of highly convenient services without the need for any additional special hardware.
