04, No), and repeat (Yes in decision 204).

When processing 202 and processing 203 are completed for all pages of the document image data (N in decision 204
o), the total number Nb of the created divided mails is stored in the RAM 4, and the process is terminated. If the document image data to be processed is not divisible by the determined number of divided units in the determination 204, the image data to be processed last is:
The number of pages is equal to or less than the determined number of division unit pages. Further, the document image data corresponding to the page that has been converted into the e-mail in the process 203 can be deleted from the image memory 8.

When the divided mail group creation processing in processing 104 of FIG. 4 is completed in this way,
Is performed (process 105). The e-mail communication sequence corresponding to the divided mail group transmission processing of the processing 105 is as shown in FIG.

That is, in FIG. 8, the judgment 102 of FIG.
A connection request is made to the specified IP address using the TCP port 25 (process 401), and a TCP connection is established with the receiving-side network facsimile machine 1b (process 402). The operation of continuously transmitting one or more e-mails until the TCP / IP connection is disconnected is started.

In a normal mail server, electronic mails transmitted in the same session are treated as independent and unrelated to each other. However, in the transmission-side network facsimile apparatus 1a according to the present invention, in a specific session, Only the group of divided e-mails created from one document image data is transmitted successively.

That is, after initializing the value of the counter variable n indicating the number of transmitted divided mails to 1 (process 403),
26. The n-th divided mail is selected from the divided mail group created and accumulated by the processing 104 in FIG. 4 (processing 404), and FIG.
(Step 405).

Then, it is determined whether or not the transmission in the process 405 is successful (decision 406), and as shown in “first divided mail” and “second divided mail” in FIG. 26, after the transmission of the mail data, If the receiving side returns an OK response and the transmission is successful (Yes in decision 406), the counter n
Is incremented (process 407), and the counter n becomes
It is determined whether the total number Nb of divided mails stored in the RAM 4 in the process 205 of FIG. 5 has been exceeded, that is, whether the transmission of the divided mail group has been completed (decision 408), and if the transmission of the divided mail group has not been completed yet, Returns to the process 404 (No in the judgment 408).

When the transmission of the divided mail group is completed (Yes in decision 408), the TC established in process 402
The P connection is disconnected (process 409), and the e-mail communication session is terminated.

In the judgment 406, as shown in the "seventh divided mail" of FIG. 27, an error occurs during the transmission of the mail data, and the code indicating the reception error (55
4) is returned and transmission fails (decision 40).
No. 6), the TCP connection established in the process 402 is temporarily disconnected (process 410), and after waiting for a predetermined time (for example, 15 minutes) (process 411), the same connection destination as that requested in step 401 is requested. Request to establish a TCP connection (step 41).
2) Return to step 404.

In this case, since the value of the counter n still indicates the divided mail in which the transmission error has occurred, the retransmission processing of the untransmitted divided mail group is performed by the processing after the processing 404. If a transmission error occurs even in the retransmission processing, the determination 406 becomes No again, and the re-transmission processing is performed again. In addition, if the upper limit is set on the number of retransmission retries, and the transmission of the divided mail group is not completed even if the upper limit of retransmission is repeated, as a final communication error, the untransmitted divided mail group is The information may be deleted from the memory 8.

Further, since each divided mail transmitted by the divided mail group transmission processing of FIG. 8 is divided on a page basis, the divided mails for which transmission has been completed may be immediately deleted. .

As described above, the transmission-side network facsimile machine 1a executes the transmission processing procedure shown in FIG.
When the document image data of the case is divided into a group of mails and successively transmitted in the same session, the receiving network facsimile apparatus 1b receives the group of divided mails.

However, in receiving e-mails in a general mail server, a plurality of e-mails received in the same session are treated as being independent of each other. Therefore, in the receiving network facsimile apparatus 1b, the transmitting network facsimile apparatus 1a is used. Therefore, it is necessary to interpret the divided mail group transmitted continuously within the same session from the document image data of one case and appropriately process it.

For this purpose, the reception-side network facsimile machine 1b performs the reception processing procedure shown in FIG. 9 corresponding to the transmission processing procedure of the transmission-side network facsimile apparatus 1a shown in FIG.

That is, the processing 402 in FIG.
After the TCP connection is established corresponding to
01), a mail reception process is performed within the same session of the e-mail communication shown in FIG. 26 and FIG. 27 (process 502).

Then, post-processing of the received document is performed on the document image data received and stored in the process 502 (process 503).

FIG. 10 shows a specific processing procedure of mail reception processing within the same session in processing 502 of FIG.

In the figure, first, one e-mail is received by the SMTP protocol procedure (step 60).
1). In this case, the received mail corresponds to the first divided mail, the second divided mail, and the like in FIG.

Then, it is determined whether or not the reception of the e-mail in the process 601 was successful (decision 602). If it was successful (Yes in the decision 602), the M received in the process 601 was received.
The body of the e-mail containing the image data encoded in the IME format is decoded in the MIME format and the original T
The IFF file is restored (process 603). The TIF
The F file contains image data composed of one or more pages divided in page units.

Then, the original image data is restored from the TIFF file (process 604). If the mail received in the process 601 is the first divided mail (Yes in decision 605), a new document file is opened in the image memory 8, and the image data restored in the process 604 is stored in the newly opened file. Newly accumulate.

In the judgment 605, if the mail is the mail after the second divided mail (No in the judgment 605), the processing 6
06, and the processing 6
The image data restored in step 04 is newly stored or linked and stored, and the image data newly restored in step 604 is linked (step 607) and stored in the image memory 8 (step 608).

Then, the process 409 in FIG.
It is determined whether the TCP connection has been disconnected in response to (step 609). If the connection has not been disconnected (No in step 609) because the subsequent divided mail is subsequently received (step 609: No), the process 601 is executed. Then, the next divided mail is received, and the subsequent processing is performed again.

In the judgment 609, if the connection is disconnected due to the completion of the reception of the divided mail group (judgment 6
(09: Yes), the file opened in the process 606 is closed (process 610), and the process ends.

As a result, the received document file stored in the image memory 8 by the process 608 is successively linked with the image data extracted from the divided mail group in the order created and transmitted on the transmitting side and transmitted. One on the side
The document image data for the case is correctly received.

In the decision 602, if the mail reception in the process 601 fails (No in the decision 602) as in the seventh divided mail in FIG. 27, the flow shifts to the decision 609 and waits for the disconnection of the connection. T (Ye of judgment 609)
s) The file opened in the process 606 is closed (process 610), and the process ends.

For the divided mail group whose transmission has not been completed on the transmitting side because the determination 602 is No on the receiving side, the transmitting side determines whether or not the divided mail group in FIG.
No. 06 and a series of processing procedures of processing 410, processing 411, and processing 412 are transmitted to the receiving side as a new divided mail group in the same session.
The mail can be correctly received by the in-session mail receiving process of the process 502 in FIG. 9 specifically shown in FIG.

The received document file stored in the image memory 8 by the process 502 is processed by the received document post-processing of the process 503.

Here, a specific processing procedure of the received document post-processing of the processing 503 is shown in FIG. Note that FIG.
21 is a processing procedure corresponding to one or a plurality of received document files that is also used as post-processing of the received document in step 1506 in the receiving processing procedure shown in FIG. 21 described later.

In the figure, first, one received document file is selected (process 701).

Then, a process of extracting image data of one page of the selected received document file in page order and recording and outputting the image data on the recording paper by the plotter 6 (process 702).
Repeat while there is an unoutput page (Ye of decision 703)
s).

If there are no unoutput pages in the judgment 703 (No in the judgment 703), it is further judged whether or not there is an unprocessed received document file (judgment 704). Is (Ye of decision 704)
s), and return to processing 701; If there are no unprocessed received document files (No in decision 704), the process ends. The processed received document file can be deleted from the image memory 8.

In this embodiment, as the post-processing of the received document file, the recording output processing on the recording paper by the plotter 6 is performed. However, the present invention depends on the contents of the post-processing of the received document file. Not limited
For example, the present invention is similarly applicable to other post-processing modes such as transferring a received document file to another computer device terminal on a LAN or transferring a received document file to a predetermined destination. Things.

In the in-session mail receiving process specifically shown in FIG. 10, a plurality of mails received in the same session are unconditionally divided into a group of divided mails created from one document image data on the transmitting side. It is interpreted as a link after receiving, but if the sending side sends multiple independent mails in the same session, the mails with unrelated contents are connected. There is a problem because it is handled as one document image data.

Therefore, as a specific processing procedure of the processing 502 in FIG. 9, instead of the processing procedure shown in FIG.
Alternatively, the processing procedure shown in FIG. 13 may be applied.

When the processing procedure shown in FIG. 12 and FIG. 13 is applied as the processing 502 in FIG.
Is set and stored in advance. Specifically, in the table 4e, a divided mail group derived from one document image data in the same session is stored in the table of the transmitting side network facsimile apparatus which transmits an e-mail according to the processing procedure shown in FIG. An IP address and / or a domain name are set and stored in advance.

Then, in FIG. 12, first, the SMTP
After storing the IP address of the transmitting side and the domain name notified as an argument of the “HELO” command from the transmitting side as shown in FIG. 26 in the RAM 4 (processing 801),
One e-mail is received by the SMTP protocol procedure (process 802). In that case, the mail received
It may be equivalent to the first divided mail, the second divided mail, etc. in FIG. 28 transmitted by the divided mail group transmission processing in FIG. 8 on the transmission side, or transmitted from a general mail server in the same session. Will be
It may be just one of a plurality of mails independent of each other.

Then, it is determined whether or not the reception of the e-mail in the process 802 was successful (decision 803). If it was successful (Yes in the decision 803), the M received in the process 802 was received.
The body of the e-mail containing the image data encoded in the IME format is decoded in the MIME format and the original T
The IFF file is restored (process 804). The TIF
The F file contains image data composed of one or more pages.

Then, the original image data is restored from the TIFF file (process 805). Then, the mail received by the process 802 is the first mail received in the same session.
If it is the e-mail (Yes in decision 806),
A new document file is opened in the image memory 8 (processing 8
07), the image data restored in step 805 is newly stored in the newly opened file (step 808).

In the judgment 806, if the mail is the mail after the second mail (No in the judgment 806), furthermore, the transmitting terminal identification information stored in the processing 801, ie, the IP address and / or the domain name It is determined whether or not is registered in the table 4e of FIG. 14 (decision 811).
Yes), the image data opened in the process 807, and the image data restored by the process 805 up to that time in the process 808 are added to the file in which the image data is newly stored or connected and stored.
05, the newly restored image data is concatenated (process 812) and stored in the image memory 8 (process 808).

If it is determined in the judgment 811 that the file is not registered (No in the judgment 811), the file opened in the step 807 is closed (step 813), a new document file is opened (step 814), and the step 805 is executed. (Step 808).

Then, the process 409 in FIG.
It is determined whether or not the TCP connection has been disconnected in response to (step 809). If the connection is not disconnected because the subsequent mail is received continuously (determination 8).
(09: No), the process returns to step 802, and the next mail is received, and the subsequent processes are performed again.

If it is determined in decision 809 that the connection has been cut off because the reception of the mail group has been completed (decision 809)
Yes), the file opened in the process 807 or 814 is closed (process 810), and the process ends.

As a result, the mail group received in the same session from the transmitting side that transmits the divided mail group is treated as the divided mail group, and the original document image data of one document is linked in order. For processing, the mail group received in the same session from the sending side such as a general mail server that does not send the divided mail group is handled as an independent mail group and processed as individual document image data. Even when the network facsimile apparatus 1a according to the present invention and a general mail server are mixed, the network facsimile apparatus 1b on the receiving side performs the mail receiving process in the same session even when the network facsimile apparatus 1a according to the present invention and the general mail server are mixed. Groups can be handled appropriately.

In the above-mentioned divisional transmission of one document image data by transmission and reception within the same session of the divisional mail group in the unit of page, since the transmission and reception of the number of divisions is performed, the e-mail by the SMTP protocol is used. The communication overhead is greater than without split transmission,
The transmission / reception of the divided mail group in the same session directly between the sending-side network facsimile machine 1a and the receiving-side network facsimile machine 1b takes 1
Since this is performed for document image data for the same case, information such as the source mail address and destination mail address is duplicated when exchanging each divided mail that constitutes a divided mail group using the SMTP protocol. There are features that are.

Focusing on this feature, the receiving side and the receiving side, which require processing different from a general mail server or the like, to process a group of divided mails transmitted and received in the same session as one document image data, are required. Keep pace with the side,
In the original SMTP protocol, if the procedure for duplicating the transmission and reception of each divided mail in the original SMTP protocol is omitted, and if the divided mail group can be transmitted and received by the shortened protocol procedure, the overhead can be reduced and more efficient communication can be performed. .

For this purpose, the transmission-side network facsimile machine 1a performs an e-mail transmission processing procedure shown in FIG.

In the figure, first, it is monitored whether a document to be read is set on the scanner 5 (No in decision 901), and if a document is set (Yes in decision 901), the receiving side It is monitored whether there is an input of the IP address (mail address omitted) of the network facsimile apparatus 1b from the operation display unit 9 (No in decision 902).
When there is an input (Yes in decision 902), the document set in decision 901 is read by the scanner 5, and the obtained document image data composed of one or more pages and transmitted is stored in an image memory. 9 (process 903).

[0108] More specifically, FIG.
In step 904, a divided mail group creation process, which is the processing procedure shown in FIG.

The divided mail group transmission processing of processing 905 is specifically the processing procedure shown in FIG. Processing 9
The e-mail communication sequence corresponding to the divided mail group transmission processing of 05 is as shown in FIG. 28 or FIG.

That is, in FIG. 16, judgment 9 in FIG.
02 to the IP address specified in TCP port 2
5, a connection request is made (process 1001),
TC between receiving side network facsimile machine 1b
A P connection is established (process 1002), and a session for e-mail communication is started thereafter.

In a normal mail server, e-mails transmitted in the same session are treated as independent and unrelated to each other. However, in the transmission-side network facsimile apparatus 1a according to the present invention, in a specific session, Only the group of divided e-mails created from one document image data is transmitted successively.

That is, after initializing the value of the counter variable n indicating the number of transmitted divided mails to 1, processing 9 in FIG.
04, the n-th divided mail is selected from the divided mail group created and stored (step 1004), and as shown in FIG. 28, both the transmitting side and the receiving side transmit and receive e-mails directly as mail servers for all the divided mails. Does not necessarily have to be sent in order to perform
m "and" RCPT "commands and the" OK "response to those commands is omitted.
The transmission is performed according to a shortened TP protocol procedure (process 1005).

As a form of protocol shortening in the processing 1005, as shown in FIG. 29, “MAIL Fr
om "command and" RCPT "command and the" OK "response to those commands
It may be performed only once before the start of transmission of the divided mail group in the P shortening protocol, and the notification of the source mail address and the destination mail address may be performed.

Then, it is determined whether or not the transmission in the process 1005 is successful (decision 1006), and as shown in the “first divided mail” and the “second divided mail” in FIG. 28 and FIG. Is transmitted from the receiving side after the transmission, and the transmission is successful (Y in decision 1006)
es), the counter n is incremented (step 100
7) It is determined whether the counter n has exceeded the total number Nb of divided mails stored in the RAM 4 in the process 205 of FIG. 5, that is, whether the transmission of the divided mail group has been completed (decision 100).
8) If the transmission of the divided mail group has not been completed yet (No in decision 1008), the flow returns to the processing 1004.

If the transmission of the divided mail group is completed (Yes in decision 1008), the TCP connection established in the process 1002 is disconnected (process 1009), and the e-mail communication session is ended.

If it is determined in the judgment 1006 that an error occurs during the transmission of the mail data and a code (554 or the like) indicating the reception error is returned from the receiving side and the transmission fails (No in the judgment 1006), the processing is performed. The TCP connection established in 1002 is temporarily disconnected (processing 101
0), and after waiting for a predetermined time (for example, 15 minutes) (process 101)
1), a TCP connection is established by requesting a connection to the same destination as that requested in the process 1001 (process 1012), and the process returns to the process 1004.

In this case, since the value of the counter n still indicates the divided mail in which the transmission error has occurred, the retransmission processing of the unsent divided mail group is performed by the processing after the processing 1004. If a transmission error occurs even in the retransmission processing, the determination 1006 becomes No again, and the re-transmission processing is performed again. In addition, if the upper limit is set on the number of retransmission retries, and the transmission of the divided mail group is not completed even if the upper limit of retransmission is repeated, as a final communication error, the untransmitted divided mail group is The information may be deleted from the memory 8.

Further, since the divided mails transmitted by the divided mail group transmission processing of FIG. 16 are divided in page units, the divided mails for which transmission has been completed may be immediately deleted. .

As described above, the transmission-side network facsimile machine 1a executes the transmission processing procedure shown in FIG.
One document image data is divided into divided mail groups, and SMT
If transmission is performed sequentially in the same session by the P shortening protocol procedure, the receiving network facsimile machine 1b receives the divided mail group.

For this purpose, the receiving-side network facsimile machine 1b responds to the transmission processing procedure in the transmitting-side network facsimile machine 1a shown in FIG.
The reception processing procedure shown in FIG. 9 is performed.

In this case, the processing procedure shown in FIG. 11 is applied as a specific processing procedure of the received document post-processing in the processing 503 in FIG. 9, but the in-session mail receiving processing in the processing 502 is as follows. The processing procedure of FIG. 17 is applied.

In FIG. 17, first, one electronic mail is received by the procedure shown in FIG. 28 or FIG. 29 corresponding to the SMTP shortening protocol procedure in the divided mail group transmission processing shown in FIG. 110
1). In this case, the received mail corresponds to the first divided mail, the second divided mail, and the like in FIGS. 28 and 29.

Then, it is determined whether or not the reception of the e-mail in the process 1101 was successful (decision 1102). If the reception was successful (Yes in the decision 1102), the image data encoded in the MIME format received in the process 1101 was received. Is decoded in the MIME format to restore the original TIFF file (process 1103).
The TIFF file contains image data composed of one or a plurality of pages divided in page units.

Then, the original image data is restored from the TIFF file (process 1104). And processing 110
If the mail received in step 1 is the first divided mail (Yes in decision 1105), a new document file is opened in the image memory 8, and the image data restored in step 1104 is newly stored in the newly opened file. I do.

In the judgment 1105, if the mail is the mail after the second divided mail (No in the judgment 1105), the image data opened in the processing 1106, and the image data restored by the processing 1104 so far in the processing 1108 is newly stored or linked. The stored file is linked to the image data newly restored by the process 1104 (process 110
7) The image data is stored in the image memory 8 (process 1108).

Then, the processing 10 in FIG.
It is determined whether or not the TCP connection has been disconnected corresponding to 09 (determination 1109). If the connection is not disconnected because the subsequent divided mails are subsequently received (No in determination 1109), processing 1101 is performed. Then, the next divided mail is received, and the subsequent processing is performed again.

If it is determined in the decision 1109 that the connection has been disconnected due to the completion of the reception of the divided mail group (Yes in the decision 1109), the file opened in the process 1106 is closed (process 1110), and the process is terminated. .

As a result, the received document file stored in the image memory 8 by the processing 1108 is successively linked with the image data extracted from the divided mail group in the order of creation and transmission on the transmission side and transmitted. One side of the document image data on the side is correctly received.

If it is determined in step 1102 that the mail reception in step 1101 has failed (YES in step 1102)
s) The flow shifts to decision 1109 and waits for the connection to be disconnected (Yes in decision 1109), followed by processing 1106
Close the file opened in step (processing 111
0), the process ends.

For the divided mail group that has not been transmitted since the judgment 1102 is No, the transmitting side determines No. 1006, 1010, and 101 in FIG.
1 and a series of processing 1012, the receiving side transmits as a new group of divided mails in the same session. Therefore, the mail in the same session of processing 502 in FIG. 9 specifically shown in FIG. Correct reception is possible by the processing.

As described above, since the transmitting side and the receiving side support the SMTP shortening protocol procedure, even if the protocol is shortened, transmission and reception of the divided mail group can be performed correctly.

However, for the transmitting side, the receiving side is, and for the receiving side, the transmitting side is the S side shown in FIG. 28 or FIG.
In an environment where there is a possibility that the mail server is a general mail server that does not support the MTP shortening protocol procedure, if the document image data is unconditionally converted into a divided mail group and transmitted by the SMTP shortening protocol procedure, The network according to the present invention may not be able to process properly, but the receiving side also converts mails received in the same session from document image data into divided mails and sends them using the SMTP short protocol procedure. Facsimile machine 1
There is a possibility that it is not possible to discriminate whether the message is sent from a or a normal mail group sent from a general mail server or the like and appropriately process it.

Therefore, the transmitting-side network facsimile machine 1a performs an e-mail transmission processing procedure shown in FIG.

In the figure, first, it is monitored whether an original to be read is set on the scanner 5 (determination 1201).
When the document is set (decision 120).
1), and further monitors whether there is an input of the IP address / mail address of the receiving side network facsimile machine 1b from the operation display unit 9 (No in the judgment 1202), and if there is an input (No in the judgment 1202). Yes), the document set in the judgment 1201 is read by the scanner 5, and the obtained document image data of one or a plurality of pages to be transmitted is stored in the image memory 9 (process 1203).

Then, the I input in the judgment 1202
The destination indicated by the P address is R, as shown in FIG.
Receiving terminal registration table 4 preset and stored in AM4
It is determined whether the destination registered in f is a destination corresponding to the reception of the divided mail group in the SMTP shortening protocol procedure (determination 1204).

If the destination is the destination registered in the table 4f (Yes in the judgment 1204), specifically, the divided mail group creation processing as the processing procedure shown in FIG. 5 is performed (processing 1205). Further, more specifically, a divided mail group transmission process, which is the processing procedure shown in FIG. 16, is performed (process 12).
06).

Thus, when the receiving side is a destination corresponding to the reception of the divided mail group in the SMTP shortened protocol procedure, the document image data is converted into the divided mail group and correctly transmitted by the SMTP shortened protocol procedure. Will be.

On the other hand, in the judgment 1204, if the other party is not registered in the table 4f (decision 1
204, the undivided mail creating process is performed (process 1).
207) Further, an undivided mail transmission process is performed (Process 1).
208).

The undivided mail creating process in process 1207 is as follows.
Specifically, the processing procedure is as shown in FIG.

In the processing procedure shown in the figure, first, the image data of all pages of the document image data acquired in the processing 1203 of FIG. 18 is collectively converted into a TIFF file (processing 13).
01), a procedure for further converting the TIFF file into a MIME format e-mail (process 1302).

The undivided mail transmission processing of processing 1208 is as follows.
Specifically, the processing procedure is as shown in FIG. Process 120
The e-mail communication sequence corresponding to the undivided mail transmission process of No. 8 is as shown in FIG.

In the processing procedure shown in FIG. 20, first, the TCP address is assigned to the IP address designated in the judgment 1202 in FIG.
A connection request is made using the port 25 (processing 14
01), a TCP connection is established with the receiving terminal (process 1402), and a session for e-mail communication is thereafter started.

The undivided mail created by the processing 1207 in FIG.
Transmission by the P protocol (processing 1403), and processing 14
In step 1404, the TCP connection established in step 01 is disconnected, and the e-mail communication session is terminated.

Accordingly, if the receiving side is a destination that does not support reception of the divided mail group in the SMTP shortened protocol procedure, the document image data is converted into a normal undivided mail and the normal SMTP protocol is used. Will be transmitted correctly.

On the other hand, the network facsimile machine 1b on the receiving side performs the receiving processing procedure shown in FIG.

In the figure, after a TCP connection is established in response to a connection connection request on the transmitting side (process 1501), as shown in FIG. 28, FIG. 29, FIG. 30, etc. Then, the domain name notified as an argument of the “HELO” command from the transmitting side is acquired as transmitting terminal identification information and stored in the RAM 4 (processing 1502).

The transmission terminal identification information acquired in the process 1502, that is, the IP address and / or domain name is stored in the table 4e of FIG. 14 (in this case, the transmission terminal corresponding to the transmission of the divided mail group by the SMTP shortening protocol procedure is used. It is determined whether it is registered in (registered) (step 1503). If it is registered (Yes in determination 1503), a divided mail group reception process within the same session is performed (process 1504) and registered. If not (No in determination 1503), the normal mail receiving process in the same session is performed (process 1505).
The received document post-processing, which is the processing procedure shown in FIG.
506).

The processing for receiving the divided mail group in the same session in the processing 1504 is specifically the processing procedure shown in FIG. 23 and FIG.

First, in FIG. 23, FIG. 28 or FIG.
One e-mail is received by the SMTP shortening protocol procedure starting from the DATA command shown in FIG. 9 (processing 1601). In this case, the received mail corresponds to the first divided mail, the second divided mail, and the like in FIGS. 28 and 29 transmitted by the divided mail group transmission processing shown in FIG. 16 on the transmission side.

Then, it is determined whether or not the reception of the e-mail in the process 1601 was successful (determination 1602). If the reception was successful (Yes in the determination 1602), the image data encoded in the MIME format received in the process 1601 was received. Is decoded in the MIME format to restore the original TIFF file (process 1603).
The TIFF file contains image data composed of one or more pages.

Then, the original image data is restored from the TIFF file (process 1604). And processing 160
1 is the first mail received in the same session (Yes in decision 1605)
s), a new document file is opened in the image memory 8 (process 1606), and the image data restored in process 1604 is newly stored in the newly opened file (process 1608).

In the judgment 1605, if the mail is the mail after the second mail (No in the judgment 1605),
The image data opened in the process 1606 and restored by the process 1608 up to that point in the process 1604 is added to the file in which the image data is newly stored or connected and stored.

Is decoded in the MIME format to restore the original TIFF file (process 1703).
The TIFF file contains image data composed of one or more pages.

The original image data is restored from the TIFF file (processing 1704). Then, a new document file is opened in the image memory 8 (processing 1705), and the image data restored in the processing 1704 is newly stored in the newly opened file (processing 1706).
The file opened in step 706 is closed (processing 1
707)

If the QUIT command has not been received (No in decision 1708), the process returns to step 1701 and Q
If a UIT command is received (Y in decision 1708)
es), and waits for disconnection of connection (N in decision 1709)
o loop), when the connection is disconnected (decision 17)
