Abstract

PURPOSE:To perform an operator call immediately after termination by providing an operator call command detecting means which detects an MF signal transmitted by a calling-side telephone set and discriminates the specific code of the MF signal. CONSTITUTION:When a calling subscriber pushes dial buttons after the line is connected, the MF signal detecting circuit of a network control unit 6 detects its MF signal and a system control part 9 identifys whether or not the pushed number or code is a preset code or not. When the code and respective signals are not detected, an NSF signal and a DIS signal are sent out at constant intervals of time and the code and signals are detected during the period. At this time, the system control part 9 operates a buzzer for calling an operator and when the operator pushes a stop key within a limited time (30 seconds), the system control part 9 controls a communication control part 4 and the network control unit 6 to send out a DCN signal and then connects the line to the side of a telephone set 10 to enter a conversation mode. Consequently, the calling subscriber and operator are allowed to have a conversation.

Description

[Detailed description of the invention] 3. Detailed description of the invention [Technical field] The present invention relates to facsimile devices.

[Prior art] When a facsimile machine equipped with an automatic reception function detects a calling signal, it connects to a line and sends a cED signal and a mouth I to the calling party.
Send s times the signal. On the other hand, from the calling side, DC3
No. m, etc. are transmitted and a predetermined transmission control operation is performed.

By the way, in the above case, if the calling side does not send the ocs (H, etc.), the above DIS
The system repeatedly sends out signals, etc., and after 20 seconds has elapsed, a buzzer sounds to indicate an operator call. At this time, when the operator picks up the handset of the telephone and presses the stop button on the facsimile machine, the buzzer stops ringing, the line is switched to the telephone, and the facsimile machine enters call mode.

As a result, if the calling party intends to talk to the called party without connecting the facsimile machine to the line, the two parties can talk to each other.

However, when the calling party calls facsimile #Ar11 with the auto-receiver 4n function for the purpose of making a call, it takes a long time, for example 20 seconds, from the time the call arrives until the operator call is made. There was a problem that it took a while.

[Objective] It is an object of the present invention to provide a facsimile machine that solves the above-mentioned problems and can immediately make an operator call after receiving a single call.

[Configuration] For this reason, the present invention detects an MF multiplied signal transmitted to a facsimile machine by operating a button on a calling party's telephone, and detects an operator call command to determine whether the MF multiplied signal indicates a predetermined code. have the means,
This facsimile apparatus is characterized in that, after receiving a call, if a predetermined transmission procedure signal is not received and an MF multiplied signal of the predetermined code is received, an operator call buzzer is sounded to call an operator.

FIG. 1 shows a block configuration diagram of a facsimile machine according to an embodiment of the present invention. In FIG. While accumulating
This is an image memory that stores image data received in "confidential reception mode" or the like. Further, 3 encodes the image data to be transmitted using a predetermined method to compress the amount of data by converting it into i-quantized data, and also decodes the encoded image data to be received and restores it to the original image data.Encoding 1! [This is the quantification section. Further, reference numeral 4 denotes a communication control section that transmits and receives facsimile signals according to a predetermined transmission control procedure.

5 is a modem for modulating the transmitted signal and demodulating the received signal; 6 is for transmitting an MF multiplied signal, which is a dial signal, to the telephone line of the telephone line and detecting the transmitted liver signal; and a modem for transmitting and receiving the facsimile signal. This is a network control device that performs line control.

Further, 7 is a plotter for recording the received image data;
is an operation display section which is provided with each 'Fg1 operation button, a display, a buzzer for system calls, etc., and allows the operator to arbitrarily operate this facsimile machine, and also displays messages etc. from the facsimile machine to the operator.

9 indicates each of the above sections 1 to 9 according to the settings on the operation display section 8.
This is a system control unit that controls 8. In addition.

10 is a telephone for making calls.

The facsimile machine of this embodiment has the above-described configuration, and operates as follows when the facsimile machine (2) is called by a calling party for the purpose of making a telephone call.

Figure 2 shows the reception processing operation of this facsimile machine.
An example of the communication procedure with the calling party in the above case is shown in FIG. In FIG. 2, when the calling party picks up the handset of the telephone and dials the telephone number of this facsimile machine, the network control device 6 detects the ringing signal from the line and processes 1.
1), connect the line (process 12).

By the way, the network control unit @6 is equipped with an MF signal detection circuit, and when the caller presses the dial button on the phone after the line is connected, it detects the MF (number 8) and displays the number. The system control section 9 also detects whether the pressed number or code is a preset code.

Detection of the above-mentioned liver Igo is performed, for example, at 3.5 seconds after the above-mentioned connection a
for a certain period of time of seconds, and if received, identify whether it is a preset code (process 13);
Here, when the predetermined code is not detected (processing 1
(N) of 3), transmits the CHD signal (processing 14) 6. Next, transmits the NSF signal and the DIS signal (processing 15).

Each of the above signals is transmitted in order to execute a predetermined transmission control procedure when the calling party is a facsimile machine.

Next, for a certain period of time, for example, 3 seconds, the process is performed to detect whether or not a predetermined code is received in the same manner as above (16), and at the same time, the Nss-i= signal or DC5 signal that is sent when the calling party is a facsimile machine is received. Detect whether (
Processing 17).

When the above code and each signal are not detected (processing 16
From N to process 17 N), the system control unit 9 checks the elapsed time after the line connection, and if it is within a predetermined time limit of 30 seconds, for example, returns to process 15 (process J!1).
18 N). As a result, the above N5F (7! Feng and 013
m is transmitted at regular intervals, during which time the above code and the above signal are detected.

Also, place]! ! When the predetermined time has elapsed in step 118 (Y in process 18), the system control unit 9
and network control bag N6, and after transmitting the DCN signal, the line is restored (processing 19).

On the other hand, if a caller presses a predetermined button on the telephone during the code detection period in process 13 or process 16, the system control unit 9 identifies this. This code is set to a code that is not used in normal dial operations, such as "*a'".

At this time, the system control unit 9 sounds the buzzer for operator call (process 20), and waits until the stop key on the operation display unit 8 is pressed (N in process 21).
Processing 17. Similar to process 18, sending and detecting the transmission procedure signal and determining the time limit are repeated (N in processes 22 to 24).
(Proceed to process 21).

Here, when the operator presses the stop key within the time limit (■ in process 21), the system control unit 9 controls the communication control unit 4 and the network control device 2!6, and the DCN
After sending the signal, the line is connected to the telephone 10 side and the conversation mode is set, thereby allowing conversation between the caller and the operator (process 25). Once this conversation is over,
Return the telephone handset and restore the line (Process 19)
).

FIG. 3 shows the operation when a predetermined code is received in the process 16 described above.

By the way, if the calling party connects a facsimile machine not for the purpose of talking as mentioned above, but for sending a document,
When the NSF number and the DIS signal are transmitted in the process 15, the calling party's facsimile machine transmits the NSS signal or the DC signal.
3 signals are transmitted. Here, when the signal is detected (V) of process 17, an image reception process is performed according to a predetermined transmission procedure (process 26).

As described above, in this embodiment, the MF multiplier, which is a pushbutton dial signal transmitted from the telephone of the calling party during the idle time when a facsimile lt receives an incoming call and transmits a predetermined transmission procedure signal intermittently. When a signal is detected and the signal is a predetermined code, a buzzer for an operator call is sounded. This allows the operator to start a conversation by picking up the handset and pressing the stop key on the facsimile machine, allowing the caller to immediately place an operator call without having to wait for a certain period of time, say 20 seconds, as required in the past. . This makes it possible to quickly call the other party and have a conversation with the other party.

Although this embodiment shows an example in which the NSF signal and NSS signal are transmitted and detected with non-standard functions, the present invention is equally applicable to those with standard functions. In addition, although the calling party set the code to indicate an operator call as "*#'", the number of digits in the code was increased to prevent false detection on the receiving party, for example, 11.1. You may press +1 for 1 second and then press ``#'' for 2 seconds.

Further, when an operator call is made even after a certain period of time has elapsed as in the conventional case, it is preferable to make it possible to distinguish between the buzzer sound at that time and the buzzer sound when the above-mentioned code from the calling party is detected.

Furthermore, if the liver signal can be received during transmission of a CED signal, NSF signal, NSS signal, etc., it goes without saying that it is better to detect the code during that period as well.

Furthermore, by setting a plurality of the above codes of W1 type, it is possible to arbitrarily apply the code not only to an operator call but also to switch a called facsimile machine from a receiving state to a transmitting state, for example.

[Effects] As described above, according to the present invention, after receiving a call, the facsimile machine performs the predetermined transmission procedure (G+-';3' is not sent from the calling party and indicates a preset code from the one-calling telephone). When a stomach signal is sent, it is detected and an operator call is made, so that the caller can immediately call the operator of the destination by pressing the button on the telephone after confirming the incoming call. Become so.
