Those having a document reading function such as dpi (dpi = (dot / 25.4 mm)) and a color image communication function are also in practical use.

For example, when a read original is read at a resolution of 1600 dpi, the number of pixels of the image data obtained by reading is the standard resolution (8 (dots / mm) in the main scanning direction and 3.75 in the sub scanning direction). (Line / mm)), which is a huge amount of 100 times or more, and even if the image data of such a huge amount of data is encoded and compressed, the data amount of the transmission image information obtained by that is still huge. However, the communication time will be very long.

Here, if the communication line used between the transmitting and receiving terminals is a constant connection line such as a leased line, it is unnecessary to worry about billing even if the communication time becomes long, but it is not necessary for ordinary public If the network is used as a communication line, the charges will be excessive and the communication cost will be increased.

Further, even if the always-on connection line is used, the long communication time means that the facsimile machine performing the communication operation cannot perform other communication operation, and the facsimile machine operates. The effective use of is hindered.

If the communication status continues for an excessively long time, the transmission operation is temporarily interrupted, and, for example, the reading conditions of the original image are examined and reset, and then again.
It is possible to take measures such as performing a transmission operation.

However, even if the user of the receiving side terminal wants to continue the interrupted receiving operation after interrupting the receiving operation and performing another communication operation, for example, such a situation occurs. If the user of the terminal on the sending side is not notified, it cannot be dealt with.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a facsimile apparatus capable of accepting interruption of reception from a user of a receiving terminal during image information communication.

DETAILED DESCRIPTION OF THE INVENTION Referring to the accompanying drawings,
Embodiments of the present invention will be described in detail.

FIG. 1 shows a group 3 facsimile apparatus according to an embodiment of the present invention.

In FIG. 1, the system control unit 1 performs control processing of each unit of the group 3 facsimile apparatus and predetermined group 3 facsimile transmission control procedure processing, and the system memory 2 includes the system control unit 1 Stores a control processing program executed by the computer, various data necessary for executing the processing program, and the like, and constitutes a work area of the system control unit 1. The parameter memory 3 is used for the group 3 facsimile apparatus. The clock circuit 4 is for storing various kinds of information peculiar to the clock, and the clock circuit 4 is for outputting current time information.

The scanner 5 is for reading an original image at a predetermined resolution, the plotter 6 is for recording and outputting an image at a predetermined resolution, and the operation display unit 7 is a group 3 facsimile. It is used to operate the device and consists of various operation keys and various indicators.

The encoding / decoding unit 8 is for encoding and compressing the image signal and for decoding the encoded and compressed image information into the original image signal.
This is for storing a large amount of image information in a coded and compressed state.

The group 3 facsimile modem 10 is for realizing the modem function of the group 3 facsimile, and has a low speed modem function (V.21 modem) for exchanging transmission procedure signals and mainly exchanging image information. High-speed modem function (V.17 modem,
V. 34 modem, V.34. 29 modem, V.29. 27ter modem etc.).

The network control device 11 is for connecting the group 3 facsimile device to the analog public network PSTN and has an automatic call originating / receiving function.

These system control unit 1, system memory 2, parameter memory 3, clock circuit 4, scanner 5, plotter 6, operation display unit 7, encoding / decoding unit 8, image storage device 9, group 3 facsimile modem. 10 and the network control device 11 are connected to an internal bus 12, and data is exchanged between these respective elements mainly via the internal bus 12.

Data is exchanged directly between the network control device 11 and the group 3 facsimile modem 10.

In this embodiment, at the time of image communication in the ECM mode, the group 3 facsimile apparatus on the receiving side can give an instruction to interrupt the communication.

For example, the reading resolution of the scanner 5 is 1
It is set to a very high resolution such as 600 dpi,
When the data amount of the transmission image information is very large, when the image information communication is performed in the ECM mode, the communication operation as shown in FIG. 2 is performed.

That is, first, the transmission originals set in the scanner 5 are read one by one at the designated resolution, and the image data obtained thereby is encoded and compressed by the encoding / decoding unit 8 to obtain it. The image information is stored in the image storage device 9.

Next, the group 3 facsimile machine on the transmitting side makes a call to the group 3 facsimile machine on the receiving side, and when the receiving side responds and the line is established, the signal CNG is sent out to notify the start of the facsimile call. .

As a result, the receiving side responds with the signal CED for notifying that the terminal itself is a group 3 facsimile machine, and subsequently, the signal NSF for notifying the option communication function of the terminal itself, the identification of the terminal itself. The signal CSI for notifying the information and the signal DIS for notifying the standard communication function of the own terminal are sequentially responded to the transmitting side. Further, in this case, the signal NSF includes information indicating that the communication interruption procedure in the ECM mode is provided as the unique mode.

The transmitting side receives the signal NS received from the receiving side.
A signal DCS / TSI (signal for notifying terminal information) for deciding a communication function to be used at that time based on the contents of F and DIS and notifying the decided communication function, or a signal After sending NSS (a signal for notifying an optional function) to the receiving side, a signal TCF is sent for performing modem training at the set modem speed. In this case, the ECM mode is designated by the signal DCS / TSI or the signal NSS.

On the receiving side, the signal DCS / TSI or
When the signal NSS is received, the communication function of the own terminal is set based on the received content, the signal TCF is received, and a predetermined modem training operation is performed. Signal T at this time
When the CF reception result is good, a signal CFR is returned to prepare for the reception of image information. Also, in this case, ECM
Mode communication operation is set.

As a result, the transmission side performs the ECM mode transmission operation. In this ECM mode transmission operation, the transmission image information is transmitted in a plurality of predetermined data lengths (64 octets or 2
It is divided into frames of 56 octets), and a maximum of 256 consecutive frames are created to create one image information block, and a transmission operation is performed using this image information block as one transmission unit.

For example, when the data length of the transmission image information is divided into n blocks, each block PIX
# 1 to PIX # n are transmitted. Also, block PIX #
When transmitting the image information from 1 to PIX # (n-1), a signal PPS-NULL for notifying that there is a subsequent block is transmitted as a post-transmission command. When the final block PIX # n is transmitted, the signal PP is transmitted as a post-transmission command.
Send S-EOP.

On the other hand, on the receiving side, each block P
When IX (# 1 to #n) is received, it is checked whether or not there is a reception error in the frames included in the received block. If all the frames have no reception error,
A signal MCF for notifying that is sent as a response. On the other hand, when there is a reception error in one or more frames, a signal PPR including information (error map data) representing the frame is sent as a response to request retransmission of the error frame data.

On the transmitting side, after transmitting one block,
When the signal MCF is received from the receiving side, it is confirmed that the block has been normally transmitted, and the transmission operation of the next block is performed. When the signal PPR is received from the receiving side, only the image information of the frame designated by the error map data included in the signal PPR is retransmitted.

In this way, by repeating the retransmission request on the receiving side until the transmission errors of all the frames are eliminated, it is possible to record and output an error-free received image on the receiving side.

Here, if the data amount of image information is very large as described above, the number of blocks to be transmitted will also be very large. At this time, if the user on the receiving side finds it difficult to maintain the communication operation, the user operates and inputs an instruction to interrupt communication. Further, at the time of the operation input of the communication interruption instruction, it is possible to input the restart condition information such as the waiting time until the communication is restarted and the image mode designating the resolution of the image desired to be received.

For example, as shown in FIG. 3, when the instruction to interrupt the communication is given during the communication of the block PIX # m, the receiving side sends an interrupt request as a response signal of the block PIX # m. A signal MCF including the information indicating the information and the restart condition information is returned to the transmitting side.

Upon receiving the interruption request signal MCF, the transmitting side immediately terminates the communication operation and sends out the signal DCN to restore the line. In addition, the fact that the transmission operation has been interrupted is displayed and output on the operation display unit 7, and the signal MC
The information of the resumption condition included in F is acquired, and the waiting time until resumption and the image mode at the time of resumption are determined. The interruption display of the transmission operation may be recorded and output from the plotter 6 as a report.

On the transmitting side, after the waiting time until resuming elapses, the image mode designated at the time of resuming is examined, and if the image mode of the image information accumulated in the image accumulating device 9 is different, The accumulated image information is converted into original image data by the encoding / decoding unit 8, and the converted image data is subjected to resolution conversion processing or the like to create image data in a specified image mode. . Next, the created image data is encoded and compressed by the encoding / decoding unit 8, and the image information obtained thereby is stored in the image storage device 9 as the image information at the time of retransmission.

In this way, when the image information at the time of retransmission is prepared, the transmitting side makes a call to the receiving side group 3 facsimile machine and performs the above-mentioned ECM mode transmitting operation.

When the transmission image information has a plurality of pages,
The image information transmitted at the time of restart may include all the pages of the image information transmitted first, or may be only the pages excluding the pages that could be transmitted by the first transmission operation.

In this way, in this embodiment, depending on the circumstances of the user of the receiving side group 3 facsimile apparatus,
Since the image information transmitting operation can be interrupted from the receiving side, flexible communication operation becomes possible. Further, since the resumption condition such as the image mode when resuming the communication can be set by the user on the receiving side, it is convenient because the communication operation reflecting the intention of the user on the receiving side can be performed.
