Abstract

PURPOSE:To facilitate the interrupt transmission during reception by storing the call code of a transmission source and requesting the transmission to the transmission source by said call code after stopping the transmission of the transmission source to perform the interrupt transmission. CONSTITUTION:An operation part 4a is provided with an interrupt transmission indicating button 4b, and the transmission source code received together with image data is stored in a transmission source code memory 10. An interrupt transmission control part 11 sends a stop command signal, which stops the transmission, to the transmission source when the interrupt transmission indicating button 4b is operated during the receiving operation, and the control part 11 sends an end signal to a main conrol part 3a when the interrupt transmission is terminated. Thus, the interrupt transmission is performed during the receiving operation, and the main control part 3a reads out said transmission source code and dials automatically from an automatic transmitting part 9 to call the transmission source when the interrupt transmission is terminated, and polling is performed from the main control part 3a.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a facsimile (hereinafter referred to as FAX) communication device, and in particular is capable of restarting reception after interrupting an emergency transmission during reception. The present invention relates to a facsimile communication device.

2. Description of the Related Art In recent years, FAX communication has been put into practical use for transmitting a document, figure, etc. to a remote location using a communication line. FAX communication is a process in which sending and receiving devices between users are usually connected through a switchboard and a communication line such as a subscriber telephone line, and document communication is performed between the users. The document is then recorded on recording paper and reproduced.

The FA'X communication device normally has the function of sending and receiving, but while one of the functions is in operation, the other function cannot be operated, so when an emergency transmission is required during the reception operation, There is a need for a method that allows interrupt transmission and also allows restarting interrupted reception after the interrupt transmission is completed.

[Conventional technology]

FIG. 3 shows a block diagram of the FAX communication device.

In the figure, a reading unit 2 has a function of reading a document 1 with an image sensor (not shown) and converting it into image data.

The main control unit 3 performs sequence control of transmission and reception, and has the function of establishing pre-transmission/reception procedures with the destination based on the destination code input from the operation unit 5, and the function of establishing the pre-transmission/reception procedure with the destination based on the destination code input from the operation unit 5. It has a function of binary converting, compressing and transmitting, and a function of decompressing the received image data and sending it to the recording unit 5, and also has a device-specific (sender) code as a transmitting side function (not shown). and a memory (not shown) for storing the code of the polling destination as a receiving side function.

The operation unit 4 includes a keyboard having operation buttons (not shown) for manually inputting a transmission button, a reception S port, a transmission destination code, a polling destination code, a transmission time, and the like.

The recording unit 5 has a function of printing on recording paper according to the received signal to create a recorded document.

The transmission control unit 6 has a function of controlling transmission and reception of image data.

The modem 7 has a function of modulating and demodulating image data and the like.

Network Control Unit
(hereinafter referred to as NCU) 8 has a function of controlling connection and disconnection of the circuit switching network.

The automatic calling section 9 has a function of calling a receiving station by automatic dialing at a predetermined time according to a command from the main control section 3.

With such a configuration and function, in the case of transmission, the operator first enters the code of the destination from the operation unit 5, calls the receiving station, and sends (by operating the H port, the operator connects to the destination, The original 1 is read by an image sensor, converted into image data, sent to the main control unit 4, converted into a binary value, and compressed.The image data is then transmitted page by page by the modem 7 under the control of the transmission control unit 6. It is modulated and sent to the line for the receiving station via the NCU 3. At this time, a source code is also added and transmitted.

At the receiving station (here, the operation of the receiving station will be explained using the receiving function shown in Fig. 3), the received image data is sent to the main controller 3.
0 is decompressed and sent to the recording section 5 and recorded on recording paper.
The unique code of the sender is recorded at a predetermined position on the recording paper.

When polling is performed, a line is connected by automatic dialing of the automatic transmission section 9 and a transmission request is made using the polling destination code stored in the memory.

Transmission and reception are performed in this way, but it is not possible to transmit and receive at the same time.

(Problems to be Solved by the Invention) As described above, in the conventional method, even if the device is equipped with transmitting/receiving functions, it is not possible to operate both functions at the same time. If it is in the middle of the day, you will need to wait for the reception to finish, or watch the line from time to time.

Moreover, if there is an urgent need to send, there is a way to stop the reception, but once the transmission is stopped, the sending side has to perform the retransmission operation, and if the receiving side cancels it due to the recipient's convenience, the sending side will be confused. There is a problem with the cost.

[Means for solving problems]

The present invention includes an interrupt instruction means for instructing interrupt transmission during a reception operation, a transmission stop instruction means for causing a transmission source to stop transmission based on an instruction from the interrupt instruction means, and a call code of the transmission source is stored. code storage means, the facsimile communication device is configured to stop transmission by a transmission source by means of a transmission stop command means and perform interrupt transmission, and then request transmission to the transmission source using a call code stored in the storage means; By doing so, the above problems can be solved.

[Effect]

According to the present invention, instead of the conventional method in which transmission cannot be performed during reception operation, by providing an interrupt instruction means and a transmission stop instruction means, the interrupt instruction means instructs interrupt transmission during reception operation. Then, the transmission of the transmission source is stopped by the transmission stop command means, and after interrupt transmission is performed, the transmission source is called using a call code stored in the storage means and a transmission request is made, that is, polling is performed to resume reception. This makes it easy to perform emergency transmissions that become necessary during reception operations.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a block diagram showing an embodiment according to the present invention, and FIG. 2 is a flowchart of FIG. 1. The same reference numerals indicate the same objects throughout the figures.

In FIG. 1, in addition to the functions of the main control section 3 described in the conventional example, the main control section 3a also functions as an interrupt transmission control section when an interrupt transmission instruction button 4b is operated during reception operation as a receiving side. 11, and a function to control the recording unit 5 so that when a stop command signal is received, the recording paper being recorded is held on hold at the point where it is terminated without being ejected, and the termination of interrupt transmission. It has a function that immediately polls the sender whose transmission is stopped when it is notified, and when the sender receives the stop command signal, it does not eject the document 1 that is being read, but holds it when it is interrupted. It has a function of controlling the reading unit 2 so that the reading unit 2 is

In addition to the functions of the operating section 4 described in the conventional example, the operating section 4a includes an interrupt transmission instruction button 4b for instructing interrupt transmission during reception.

The sender code memory 10 is a storage means that stores the sender code received together with the image data.

The interrupt transmission control unit 11 sends a stop command signal to the transmission source to stop transmission when the interrupt transmission instruction 1 port 4b is operated during the reception operation, and when the interrupt transmission is completed, a termination signal is sent to the main control unit 3a. It has the function to send to.

Since it has such a configuration and function, a method of interrupt transmission during reception operation will be explained with reference to the flowchart of FIG. 2. (Here, the functions of the receiving side and the transmitting side will be explained with reference to Fig. 1.) - When transmission from the sending side starts, the calling code of the sending side is sent to the receiving side and stored in the sending side code memory 10. Ru.

■When an emergency transmission is required on the receiving side, the operator gives an interrupt transmission instruction! When t14b is operated, the main control unit 13 issues a command to the interrupt transmission control unit 11, and the interrupt transmission control unit 11 sends a transmission stop command signal to the transmission source, without ejecting the recording paper being recorded. I'll put it on hold.

- On the sending side, transmission is stopped and the original 1 whose reading has been stopped is held without being ejected.

■Next, the receiving side performs the desired interrupt transmission.・■When the transmission is completed, the main control unit 3a immediately stores the sender code memory 1.
The sender code whose transmission has been stopped is read from 0, and the automatic dialer 9 automatically dials the sender to call the sender. Then, polling is performed from the main control unit 3a.

(2) The sender that has received the polling request resumes reading the pending document 1 and starts sending it.

In this way, interrupt transmission during reception can be easily performed. Therefore, there is no need to wait for transmission until the end of reception, and there is no need to interrupt reception due to the recipient's convenience and cause trouble to the transmitter.

The above example describes the case of directly recording received data, but
The present invention can also be applied to a method in which received data is stored in a data memory once and then recorded. In this case, recording is performed after combining the data received and stored before the interruption with the data received by polling.

〔Effect of the invention〕

As explained above, according to the present invention, interrupt transmission can be easily performed during reception, there is no need to wait for transmission until reception is completed, and there is no need to stop reception midway and cause trouble to the sending side. It has the effect of becoming.
