Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile system, and more particularly, a transmitting facsimile apparatus transmits image information of a document in an arbitrary page order, and a receiving facsimile apparatus sorts and records the information in a predetermined page order. Related to facsimile systems.

[0002]

2. Description of the Related Art A facsimile apparatus records and outputs received image information on a recording sheet by a plotter. As a method for discharging the recording sheet on which the image information is recorded, the image information is recorded on a recording sheet tray with its surface facing upward. There is an upward discharge method for discharging, and a downward discharge method for discharging onto the recording paper tray in the direction in which the image information is recorded.
Some of these discharge methods are fixed to one of them, but others discharge the recording paper by a method appropriately selected according to the designation of the operation display unit.

The method of discharging the received image information is determined by the page order in which the facsimile apparatus on the transmitting side transmits the image information of the original. Are discharged in a normal order or discharged in a reverse order.

[0004] Therefore, conventionally, the order of discharging the recording paper of the receiving facsimile apparatus is designated from the operation display unit,
A facsimile apparatus has been proposed which reads out received image information from an image storage memory in an order corresponding to the transfer order (see Japanese Patent Application Laid-Open No. Hei 4-238559).

The facsimile apparatus includes an image input unit for inputting an image for transmission, a transmitting / receiving unit for transmitting an input image and the like and receiving an image and the like transmitted through a line.
An image storage unit that stores the image input by the input unit, and in a facsimile apparatus that reads out and transmits the stored image, by specifying the discharge order of the receiving recording paper of the other party's facsimile apparatus, It has a reading order instructing unit for instructing the reading order of images in the order according to the discharging order.

Therefore, according to this facsimile machine, the operator of the facsimile machine on the transmitting side knows in advance the order of discharging the recording sheets of the facsimile apparatus on the receiving side, and designates the order of discharging the recording sheets from the operation display unit or the like. Thus, the transmission images stored in the image storage unit can be read out and transmitted in the order according to the discharge order, and can be discharged in the page order by the receiving-side facsimile apparatus.

That is, in the conventional facsimile apparatus, original images read in the normal or reverse order are transmitted in the normal or reverse order in accordance with the discharge order of the facsimile apparatus on the receiving side.

[0008]

However, in such a conventional facsimile apparatus, the operator of the transmitting facsimile apparatus specifies whether the recording paper discharge order of the receiving facsimile apparatus is forward or reverse. However, since the images of the document are transmitted in the order according to the designation of the forward or reverse order, the image information of the document can be transmitted only in the page order of the forward or reverse order. This was a problem in improving the usability of the device.

That is, the operator of the transmitting facsimile machine needs to know in advance the order in which the receiving facsimile apparatus discharges the recording paper. The mode may be different, such as the fine mode or the normal mode. When the image information of the document of the page having the different mode is transmitted in the normal or reverse order, the EOM signal (message end signal) is output for each page where the mode is switched. )
There is a problem that communication time is long and communication cost is high.

Therefore, according to the first aspect of the present invention, the transmitting facsimile apparatus stores the image information of the document read by the reading means in the image information storage means, and the transmission page order of the document is arbitrarily specified in page units. Then, the transmission page order of the specified document is added as a page order information to a predetermined facsimile control signal and transmitted, and the image information of the document stored in the image information storage unit is transmitted to the specified page order. The received facsimile apparatus stores the received image information in the image information storage means, acquires the page order information from the facsimile control signal, and performs the image processing based on the acquired page order information. By reading out the received image information stored in the information storage means in a predetermined page order and recording and outputting the information in the page order, the transmitting side can copy the received image information. Send the image information of the page transmission original in an arbitrary order in page units, for example, specify and transmit in the page order summarized for each reading mode, and set the recording side upward or downward on the receiving side, and appropriately set the page order or reverse order. It is an object of the present invention to provide a facsimile system which records and outputs a facsimile system which can be communicated from an arbitrary page regardless of the format of a document after completion of communication and has good usability.

According to a second aspect of the present invention, when facsimile communication is interrupted halfway, the receiving-side facsimile apparatus transmits the image information received and stored in the image information storage means up to the time of the interruption, to the page order information. On the transmission side, by reading out and recording and outputting in a predetermined page order based on
For example, if the order of the transmission pages is set from the page with the highest importance, even when it is necessary to communicate over a long distance or a line of poor quality, the transmission and reception are performed sequentially from the page with the highest importance and the predetermined page order. Sorted recording can be performed, the usability can be further improved, and even if all transmitted documents cannot be transmitted due to interruption of facsimile communication, the image information of the page to be truncated is information of low importance. It is therefore an object of the present invention to provide a facsimile system capable of relatively increasing the amount of communication information.

According to a third aspect of the present invention, when facsimile communication is interrupted halfway, the receiving-side facsimile apparatus stores the image information received and stored in the image information storage means up to the time of the interruption. Means, the image information is stored in the image information storage means together with the re-transmitted image information of the original, and the image information of the image information storage means is read out in a predetermined page order based on the page order information. By recording and outputting, when the number of pages of the document is large, the image information received before the occurrence of the communication error and the retransmitted image information are put together, and after all the pages are aligned, a predetermined page order is established. It is an object of the present invention to provide a facsimile system that can read, record, and output, and is more usable.

According to a fourth aspect of the present invention, when the receiving facsimile apparatus is interrupted during facsimile communication, the image information received and stored in the image information storage means before the interruption is stored as it is, and When waiting for retransmission to wait for retransmission of the image information following the retransmission, the retransmission waiting information for performing the retransmission waiting is added to a predetermined facsimile control signal and transmitted. The device
When the facsimile communication is interrupted, when retransmitting the image information subsequent to the image information of the original transmitted before the interruption,
If the retransmission waiting information is added to the facsimile control signal, the subsequent image information is read out from the image information storage means in the page order of the page order information and transmitted, and the retransmission waiting information is added to the facsimile control signal. Otherwise, after adding new page order information for the subsequent image information to the facsimile control signal and transmitting the same, the subsequent image information is transmitted in the page order of the page order information, so that facsimile communication is interrupted. In this case, depending on whether the receiving side waits for retransmission, the sending side and the receiving side can appropriately transmit and receive the image information whose page order has been changed and can sort and output the recorded information appropriately. The purpose of the present invention is to provide a good facsimile system.

According to a fifth aspect of the present invention, by adding the page order information to the NSF signal FIF, the transmission and reception of the image information whose page order has been changed on the transmission side and the reception side, and the sorted recording output can be appropriately performed. An object of the present invention is to provide a facsimile system with good usability.

According to a sixth aspect of the present invention, even if facsimile communication is interrupted on the way, the receiving side can determine whether to wait for retransmission by adding retransmission waiting information to the NSS signal FIF. It is an object of the present invention to provide a facsimile system with good usability by enabling transmission and reception of image information whose page order has been changed, and sorted recording output on a transmission side and a reception side.

According to a first aspect of the present invention, there is provided a facsimile system for transmitting and receiving image information between a transmitting side facsimile apparatus and a receiving side facsimile apparatus by a predetermined facsimile control procedure. The transmission-side facsimile apparatus includes a reading unit that reads an image of a document at a predetermined resolution, an image information storage unit that stores image information of the document read by the reading unit, and a transmission page order of the document in page units. Transmission order designating means that can be arbitrarily designated; page order information adding means for adding a transmission page order of the document designated by the transmission order designating means to a predetermined facsimile control signal as page order information; The image information of the original stored in the means in the page order specified by the transmission order specifying means. Control means for causing the receiving-side facsimile apparatus to transmit the image data, the receiving-side facsimile apparatus comprising: a recording means for recording and outputting an image on recording paper; an image information storing means for storing the received image information; and the facsimile apparatus. Communication information control means for obtaining the page order information from a control signal, and reading out the received image information stored in the image information storage means in a predetermined page order based on the page order information obtained by the communication information control means The above object is achieved by providing a control unit for causing the recording unit to record and output in the page order.

According to the above configuration, the transmitting facsimile apparatus stores the image information of the document read by the reading means in the image information storage means, and when the transmission page order of the document is arbitrarily specified in page units, The transmission page order of the designated document is added as a page order information to a predetermined facsimile control signal and transmitted, and the image information of the document stored in the image information storage means is received in the designated page order in the receiving facsimile. The reception side facsimile apparatus stores the received image information in the image information storage unit, acquires the page order information from the facsimile control signal, and stores the received image information in the image information storage unit based on the acquired page order information. The stored received image information is read out in a predetermined page order and recorded and output in the page order. Image information can be specified and transmitted in an arbitrary order on a page basis, for example, in a page order summarized for each reading mode, and the recording side can be properly recorded with the recording surface facing up or down on the receiving side. Output can be performed, and communication can be started from an arbitrary page regardless of the format of the document after the communication is completed, and the usability of the facsimile system can be improved.

In this case, for example, as described in claim 2, when the facsimile communication is interrupted during the facsimile communication,
The controller reads out the image information received and stored in the image information storage unit up to the time of the interruption in a predetermined page order based on the page order information obtained by the communication information controller. The recording means may cause the recording means to record and output in the page order.

According to the above configuration, when the facsimile communication is interrupted halfway, the receiving-side facsimile apparatus transmits the image information received and stored in the image information storage unit up to the time of the interruption based on the page order information. Then, the data is read out and recorded and output in a predetermined page order, so that, for example, when the transmission side sets the order of the transmission page from the page with the highest importance,
Even when communication is required over long distances or with poor quality lines, it is possible to send and receive pages in order of importance, and to sort and record them in a predetermined page order, and use a facsimile system. In addition, even if all the transmitted originals cannot be transmitted due to the interruption of facsimile communication, the image information of the page to be truncated is set to information of low importance, and the amount of communication information is relatively improved. be able to.

Further, for example, when the facsimile communication is interrupted in the course of the facsimile communication, the receiving side facsimile apparatus may receive the data by the time of the interruption. The image information stored in the image information storage means is stored in the image information storage means as it is. Thereafter, when the subsequent image information of the original is retransmitted, the subsequent image information is stored in the image information. When it is stored in the information storage means and all the image information is received,
The received image information stored in the image information storage unit is read out in a predetermined page order based on the page order information obtained by the communication information control unit, and recorded and output in the page order by the recording unit. You may.

According to the above configuration, when the facsimile communication is interrupted in the middle of the facsimile communication, the receiving-side facsimile apparatus stores the image information received and stored in the image information storage means by the time of the interruption in the image information storage means. The image information is stored in the image information storage unit together with the re-transmitted original image information in the image information storage unit, and based on the page order information, the image information in the image information storage unit is read out in a predetermined page order. Since the document is recorded and output, when the number of pages of the document is large, the image information received before the occurrence of the communication error and the retransmitted image information are collectively read out in a predetermined page order after all the pages are aligned, Recording and output can be performed, and the usability of the facsimile system can be further improved.

Further, for example, when the facsimile communication is interrupted in the course of the facsimile communication, the receiving facsimile apparatus receives the image information before the interruption and stores the image information. Means for storing the image information stored in the means as it is and waiting for retransmission of the image information subsequent to the original to be retransmitted. The retransmission waiting information to the effect is added to a predetermined facsimile control signal, and if the facsimile communication is interrupted during the facsimile communication, the transmitting facsimile apparatus transmits image information of the original transmitted before the interruption. When retransmitting the subsequent image information of the above, the control means is preceded by the facsimile control signal transmitted from the receiving facsimile apparatus. If the retransmission waiting information is added, the subsequent image information is read out from the image information storage unit in the page order of the page order information and transmitted, and the retransmission waiting information is added to the facsimile control signal. If not, the page order information adding means adds the page order information for the subsequent image information to the facsimile control signal and transmits the same, and then transmits the subsequent image information in the page order of the page order information. It may be something.

According to the above arrangement, when the receiving facsimile apparatus is interrupted during facsimile communication, the image information received and stored in the image information storage means before the interruption is directly stored to continue the original. In the case of performing a retransmission wait to wait for the image information to be retransmitted, the retransmission wait information to the effect that the retransmission wait is performed is added to a predetermined facsimile control signal and transmitted, and the transmission side facsimile apparatus When the facsimile communication is interrupted, when retransmitting the image information subsequent to the image information of the document transmitted before the interruption, if the retransmission waiting information is added to the facsimile control signal, the image information storage means The subsequent image information is read out in the page order of the page order information and transmitted, and if the retransmission waiting information is not added to the facsimile control signal, After adding the page order information to the facsimile control signal and transmitting it, the subsequent image information is transmitted in the page order of the page order information. Therefore, even if the facsimile communication is interrupted, the receiving side waits for retransmission. The transmission and reception of the image information with the changed page order and the sorted recording output can be appropriately performed on the transmission side and the reception side depending on whether or not the facsimile system is performed, and the usability of the facsimile system can be improved.

Further, for example, as set forth in claim 5, the page order information adding means may add the page order information to an NSF signal FIF.

According to the above configuration, the page order information is set to NS
Since the F information is added to the FIF, the transmission and reception of the image information whose page order has been changed and the sorted recording output can be appropriately performed on the transmission side and the reception side, and the usability of the facsimile system can be improved. .

Further, for example, as set forth in claim 6, the communication information control means transmits the retransmission waiting information to N
It may be added to the FIF of the SS signal.

According to the above configuration, the retransmission waiting information is transmitted to the
Since it is added to the S-signal FIF, even if facsimile communication is interrupted in the middle, transmission and reception of image information whose page order has been changed between the transmission side and the reception side depends on whether the reception side waits for retransmission. Reception and sorted recording output can be appropriately performed, and the usability of the facsimile system can be improved.

The RAM 12 is used as a work memory of the CPU 4 and stores various information.

When the page order of the transmission original is specified from the operation display unit 7, the page management unit 13 stores the page order as page order information, and stores the page order information in C.
At the time of transmission, the CCU 8 adds the page order information and the information indicating that the page order has been changed to the FIF of the NSF signal, which is a facsimile control signal, and transmits it to the receiving-side facsimile apparatus. Therefore,
The page management unit 13 and the CCU 8 function as page order information adding means.

Next, the operation of the present embodiment will be described. The facsimile system performs facsimile communication using the facsimile apparatus 1 as a facsimile apparatus on the transmission side and the reception side, transmits image information of a plurality of pages of the transmission original in an arbitrary specified order in page units, and the reception side specifies the page. This is characterized in that the page order is sorted and recorded based on the original page order or the reverse order.

Now, the facsimile machine 1 of FIG. 1 is installed on the transmission side and the reception side, and
It is assumed that image information of a document of a plurality of pages is transmitted and received between the facsimile machine 1 and the receiving-side facsimile machine 1.

In the facsimile apparatus 1 on the transmitting side, the operator sets a plurality of pages of the document to be transmitted on the ADF of the scanner 2 and inputs the telephone number of the facsimile apparatus 1 on the transmitting side from the operation display section 7. Set the transmission page order of the transmission original in an arbitrary page order for each page, for example, set the transmission order sequentially from the page with the highest importance among a plurality of pages, or set the transmission mode to the page read in the fine mode and the normal mode. When the pages to be read are not continuous pages, the transmission page order in which the pages are continuous can be set for each mode.

That is, the transmitting facsimile machine 1
When a transmission operation such as an operation of setting the original and inputting a telephone number of a transmission destination is performed, and a start key of the operation display unit 7 is turned on, the CPU 4 drives the scanner 2 to change the image of the original for each page. Then, the image information of the original read by the scanner 2 is temporarily stored in the SAF 5. At this time, the transmission-related information of the original, such as the reading accuracy, is displayed on the display of the operation display unit 7 for each page. Looking at this display, the transmission order (page order) of the pages can be determined for each page by operating the keys on the operation display unit 7.

Therefore, the CP of the transmitting facsimile machine 1
U4 checks whether the page order is set by the user operation as shown on the right side of FIG. 2 (step S4).
1) When the page order is set, the page order set and operated on the operation display unit 7 is changed to the page management unit 1.
3 (step S2). The CPU 4 sequentially performs the above processing, reads out the image information of the originals of all the pages, stores the read image information in the SAF 5, and stores the necessary page order in the page management unit 13. Based on the registered page order, page order information specifying the transmission order of all pages of the document is created, and the page order information created by the page management unit 13 is stored in the CC.
U8 is added to the NSF signal's FIF, ie, N
The FIF bit assignment of the SF signal is performed (step S3).

That is, the FIF of the NSF signal is bit-allocated as shown in FIG.
The FIF “page sequential setting ON / OFF” is set to “ON” when the page order is set, and “OFF” to the CCU 8 when the page order is not set. Is assigned by bit assignment based on the page order information from the page management unit 13. As will be described later, when an error occurs during facsimile communication and the image information of the document is retransmitted from the next page, the CPU 4 sends the NSF an NSF
A signal FIF “retransmission file or not” is set.

When the page order is not set by the user operation in step S1, the CPU 4
The process directly proceeds to step S4.

Then, in step S4, the CPU 4 calls the facsimile machine 1 on the receiving side, and when the facsimile machine 1 on the receiving side responds, executes the facsimile control procedure and starts transmission (step S4). At this time, the transmitting facsimile apparatus 1 transmits the NSF signal, and checks the NSS signal transmitted from the receiving facsimile apparatus 1 (step S5).

That is, the receiving facsimile machine 1
Retransmission conditions at the time of reception can be set by operating the keys on the operation display unit 7, and the retransmission conditions are set when a facsimile communication is interrupted due to a line error or the like during facsimile communication. The image information of the document of the page received and stored in the SAF 5 before the interruption is stored in the SA until the image information of the subsequent page is retransmitted.
After storing the image information in F5 and completing the reception of the image information of all pages, after arranging the pages based on the page order information, the plotter 3 waits for retransmission for recording and output,
The image information of the page received before the interruption is set by the condition setting of whether to record and output the image information on the plotter 3 without waiting for the image information of the subsequent page to be retransmitted, that is, without waiting for the retransmission. is there.

Therefore, the CP of the receiving facsimile machine 1
As shown on the left side of FIG. 2, U4 checks whether the retransmission condition is set by the user's key operation on the operation display unit 7 during standby (step P1), and when the retransmission condition is set, While the operated setting condition is stored in the page management unit 13 as retransmission waiting condition information,
The CU 8 sets retransmission conditions for the NSS signal FIF, that is, performs bit assignment of the NSS signal FIF (step P2).

That is, the FIF of the NSS signal is bit-assigned as shown in FIG.
When the facsimile communication error occurs, the image information of the page received halfway is not recorded and output, but is stored in the SAF 5 until the next page is retransmitted, that is, when waiting for retransmission, the NSS signal The CCU 8 sets the “ON / OFF of retransmission waiting on error” of the FIF to “ON”.

Then, the CPU 4 sets the NSS signal
When the bit assignment of the retransmission condition is performed, the process returns to the reception standby state (step P3), and when there is an incoming call, the call is answered and the reception is started (step P4). At the time of this incoming call, CPU4
Exchanges a facsimile control signal with the transmission-side facsimile apparatus 1 via the CCU 8, and at this time, transmits an NSS signal to which the retransmission condition is set to the transmission-side facsimile apparatus 1.

In the transmission-side facsimile apparatus 1, the CCU 8 checks the FIF of the NSS signal transmitted from the reception-side facsimile apparatus 1, and determines whether the FIF of the FIF, which is the retransmission condition set in the FIF of the NSS signal, indicates an error. Waiting for retransmission O
N / OFF ”and outputs it to the CPU 4.
Confirms the retransmission condition, that is, the NSS signal, and stores the retransmission condition information in the page management unit 13 (step S5).

Next, the CPU of the transmitting facsimile machine 1
4 sequentially reads out the image information of the transmission original from the SAF 5 in the page order of the page order information based on the page order information stored in the page management unit 13, and encodes the image information by the encoding / decoding unit 6. , Via the CCU 8 and the NCU 9 (step S6).

The receiving facsimile machine 1 transmits the image information transmitted from the transmitting facsimile machine 1 to the CPU 4.
Are sequentially received under the control of (1) and stored in the SAF 5 (step P5).

The CPU 4 of the transmitting facsimile machine 1
When the image information of all pages is transmitted without interrupting the facsimile communication due to a line error or the like, the facsimile transmission processing ends.

Then, the CP of the receiving-side facsimile machine 1
When U4 receives the image information of all pages without interrupting the facsimile communication, U4 terminates the facsimile reception and encodes the image information of the received document stored in SAF5.
After being decoded by the decoding unit 6, the data is transferred to the plotter 3, and the plotter 3 records and outputs the data on a recording sheet. At this time, CPU
4, when the received page order information is stored in the page management unit 13, the received original is read from the SAF 5 in the original page order in the normal or reverse order based on the page order information, that is, The image information of the received document stored in the SAF 5 is read from the SAF 5 in the original page order or the reverse order, and is decoded by the encoding / decoding unit 6. To make the plotter 3 record and output it on recording paper.

As described above, the transmission-side facsimile apparatus 1
Accumulates the image information of the document read by the scanner 2 in the SAF 5, and when the transmission page order of the document is arbitrarily specified in units of pages by the operation display unit 7, the page management unit 13 and the CCU 8 specify the transmission page order. The transmission page order of the manuscript is used as the page order information and is a facsimile control signal N
The SF signal is added to the FIF and transmitted.
5 is transmitted to the receiving facsimile apparatus 1 in the designated page order, and the receiving facsimile apparatus 1 stores the received image information in the SAF 5, and reads the page information from the FIF of the NSF signal. Order information is acquired, and SAF is performed based on the acquired page order information.
5 is read out in a predetermined page order and recorded and output by the plotter 3 in the page order.

Accordingly, the transmitting side can specify and transmit the image information of the transmission original of a plurality of pages in an arbitrary order on a page basis, for example, in a page order summarized for each reading mode, and transmit the image information on the recording surface. Can be appropriately recorded and output in the page order or the reverse order by turning the document upward or downward. Communication can be started from an arbitrary page regardless of the format of the document after the communication is completed, and the usability of the facsimile system can be improved. .

Further, since the transmitting side facsimile apparatus 1 adds the page order information to the FIF of the NSF signal,
The transmission and reception of the image information whose page order has been changed and the sorted recording output can be appropriately performed on the transmission side and the reception side, and the usability of the facsimile system can be improved.

Then, during the facsimile communication,
When the facsimile communication is interrupted due to a line error or the like, as shown in FIG. 2, both the transmission side facsimile apparatus 1 and the reception side facsimile apparatus 1 disconnect the line, and wait until the line is restored for a predetermined time (steps S7 and P6). ).

The CPU 4 of the transmitting facsimile machine 1
After a lapse of a predetermined time, retransmission processing is performed. At this time, first, retransmission wait condition information of the page management unit 13 is checked to determine whether the receiving side is in a retransmission wait state, that is, the image of the page received before the interruption is performed. It is determined whether or not the image information of the subsequent page is waiting to be retransmitted while the information is stored in the SAF 5 (step S8). Of the NSF signal of the NSF signal to the CCU 8 based on the page order information for designating the transmission order of the pages of the document created by the page management unit 13 again from the image information of FIG. To reset the bit assignment (step S9). At this time, CP
U4 causes the CCU 8 to set the NSF signal's FIF "whether or not to be a retransmission file" to be a retransmission file.

The CPU 4 of the transmitting facsimile machine 1
When the bit assignment of the FIF of the NSF signal is completed, the facsimile control procedure is executed similarly to the normal retransmission operation, and the transmission of the image information of the untransmitted page of the SAF 5 is started (step S10). At this time, as in the case of the transmission, the CPU 4 sequentially reads out the image information of the transmission original from the SAF 5 based on the page order information of the page management unit 13 in the page order of the page order information, and executes the encoding / decoding unit. 6 and then sequentially transmitted to the receiving facsimile machine 1 via the CCU 8 and the NCU 9 (step S
10).

The CPU of the transmitting facsimile machine 1
In step S8, when the receiving side is in the retransmission waiting state, the setting indicating that retransmission is performed is performed in the "retransmission file or not" of the FIF of the NSF signal without performing bit assignment in the page order. Then, retransmission is performed (step S10).

When the reception side facsimile apparatus 1 is interrupted during the facsimile communication, the reception side facsimile apparatus 1
4 checks the resending wait condition information of the page management unit 13 and waits for resending, that is, the image information of the page received before the interruption is accumulated in the SAF 5, and the image information of the subsequent page is resent. It is determined whether to wait until it comes (step P7). If it is not in the retransmission waiting state, the received document received before the interruption is read from the SAF 5 in the page order or reverse order based on the page order information of the page management unit 13 (step P7). P8) After being decoded by the encoding / decoding unit 6, the data is transferred to the plotter 3 and is recorded and output on recording paper by the plotter 3 (step P9).

When the recording and output of the image information of all pages of the received original received before the interruption is completed, the CPU 4 shifts to a reception standby state and waits for the transmission of the image information of the next page of the original. Wait (step P10). Also, in the retransmission waiting state in step P7, the CPU 4 shifts to the reception waiting state with the image information of the page received before the interruption being stored in the SAF 5 without recording and outputting the document, and Wait for the image information of the next page to be transmitted (step P10).

Thereafter, when the image information of the continuation page of the interrupted document is transmitted, the CPU 4 receives the image information of the continuation page, accumulates the image information in the SAF 5, and when the facsimile communication is interrupted again on the way. When the image information of all the pages is received without interruption in the same manner as described above, the SAF 5
The recording and output of the image information of the pages in the page is performed.

That is, C of the receiving facsimile machine 1
When the recording and outputting of the image information received before the interruption has already been performed, the PU 4 transmits the NSF signal of the NSF signal newly created and transmitted at the time of retransmission and stored in the page management unit 13.
Based on the page order information of F, only the image information of the retransmitted page is read from the SAF 5 in a sorted state, and is sequentially recorded and output by the plotter 3. Also, C
When the PU 4 does not record and output the image information received before the interruption and stores the image information in the SAF 5, the FIFO of the NSF signal received first and stored in the page management unit 13 is used.
Is read from the SAF 5 in a state where the image information of all the pages is sorted based on the page order information of the
To record and output sequentially.

As described above, the receiving facsimile apparatus 1
When facsimile communication is interrupted in the middle, the image information received and stored in the SAF 5 up to the time of the interruption is read out in a predetermined page order based on the page order information and recorded and output.

Therefore, the transmitting facsimile machine 1
So, for example, by setting the order of the transmission page from the page with the highest importance, even if it is necessary to communicate over a long distance or a poor quality line, it is possible to sequentially send and receive the page with the highest importance and Can be sorted and recorded in a predetermined page order, and the usability of the facsimile system can be further improved. Further, even if all the transmitted originals cannot be transmitted due to the interruption of the facsimile communication, the image information of the page to be truncated. Is less important information, and the communication information amount can be relatively improved.

When the facsimile communication is interrupted halfway, the receiving-side facsimile apparatus 1 transmits the image information received and stored in the SAF 5 up to the time of the interruption.
In the SAF 5, the image information of the SAF 5 is read out in a predetermined page order based on the page order information, and is recorded and output.

Therefore, when the number of pages of the original is large, the image information received before the occurrence of the communication error and the retransmitted image information are put together and read out in a predetermined page order after all the pages are aligned. Recording and output can be performed, and the usability of the facsimile system can be further improved.

Further, when the receiving facsimile machine 1 is interrupted during facsimile communication, the image information received and stored in the SAF 5 before the interruption is stored as it is, and the subsequent image information of the original is retransmitted. When waiting for retransmission, the retransmission waiting information to the effect that the retransmission waiting is performed is added to the FIF of the NSS signal and transmitted, and the facsimile machine 1 on the facsimile machine interrupts the facsimile communication. Then, when resending wait information is added to the FIF of the NSS signal when resending the image information subsequent to the image information of the original sent before the interruption, the SAF 5 sorts the subsequent image information from the page order. The information is read and transmitted in the page order, and if the retransmission wait information is not added to the FIF of the NSS signal, new page order information for the subsequent image information is transmitted to the NSF signal. After transmitting in addition to FIF of transmitting the image information of the continued in page order of the page sequence information.

Therefore, even when the facsimile communication is interrupted, the transmission and reception of the image information whose page order has been changed between the transmission side and the reception side and the recording and output are sorted according to whether the reception side waits for retransmission. Can be done properly,
The usability of the facsimile system can be improved.

Since the receiving-side facsimile apparatus 1 adds the retransmission waiting information to the NSS signal FIF,
Even if facsimile communication is interrupted in the middle, depending on whether the receiving side waits for retransmission, the sending side and the receiving side properly send and receive the image information whose page order has been changed, and sort the recorded output properly. And the usability of the facsimile system can be improved.

Although the invention made by the inventor has been specifically described based on the preferred embodiments, the invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the invention. It goes without saying that it is possible.

For example, in the above embodiment, NS
The page order information is set by the F signal FIF.
The retransmission waiting information is set by the FIF of the SS signal. However, the setting of the page order information and the retransmission waiting information is not limited to the facsimile control signal, and the page order information and the retransmission waiting information are appropriately set. Any facsimile control signal may be used as long as it can notify the other party facsimile apparatus.
