When the destination list registration is completed in this way, the system control unit 7 sends standard terminal function information (digital identification signal: DIS ) to the destination list, and this DTS-1tM processing will be described later.

Next, document transmission processing will be explained with reference to FIG. 25.

As mentioned above, when document transmission is selected from the Teletex communication menu, a menu for setting transmission conditions for document transmission is first displayed on the screen.

Performs transmission condition setting processing that takes in the transmission mode (normal transmission, emergency communication, etc.) set by key operation, transmission time, 2 document contents (Japanese text, etc.).

After this transmission condition setting process is completed, the document specification process reads the document name registered in the document file, displays a menu of 1 document name and list on the screen, and imports the document name to be transmitted specified by key operation. do.

After this document designation process is completed, the registered destination list is read from the destination file, a destination designation menu is displayed, and a destination designation process is performed in which the destination name specified by key operation is imported.

After the destination designation process is completed, the destination name, document name, etc. are displayed for confirmation, and if the cancellation is confirmed, the process moves to the cancellation process, and if confirmed, the process moves to the transmission preparation process described below.

In this transmission preparation process, the system control unit (SCU) 7 first records the address (dial number) of the designated destination name, the name and transmission time of the transmission document, terminal function information (digital identification signal; DI S), etc. The transmission information is transmitted to the communication control unit 9
give it to

On the other hand, 1 communication control unit (ccU) 9 starts executing the process shown in FIG. 26 in response to a predetermined command from 5CU 7, and receives the transmission information sent from 5CU 6. When information cannot be received from the 5CU7, such as during document communication, this process, such as sending and receiving information between the 5CU7, waits until the communication is completed.

Thereafter, the 5CU7 reads the mode registered in the destination list of the other party and determines whether it is a facsimile (FAX) mode or a teletex (ETEX) mode.

If the transmission mode is FAX mode, SCU9
The SCU 9 requests the file No. to the file No., and sends out a predetermined file No. in response to the request. Note that this file No. is a file number for internal processing, and for example, in the teletex mode, rTDo (T-XXXJ is used).

Therefore, 5C1J7 sends the file number received from CCUE3 to rTD○C-XX in teletex mode.
Change from XJ to rFDOC-XXXJ in FAX mode.

Then, the 5CU 7 reads the specified transmission document from the FDD 6 and saves the document to the changed file No. rF.
DOc-XXXJ is added and registered in the transmission file configured on the HDD 5, and the changed file No. is returned to the CCU 9.

On the other hand, if the transmission mode is not FAX mode,
In other words, if it is in the ETEX mode, it similarly requests the CCU 9 for file No.

Then, the teletex file No. rTDOc-XXXJ received from the CCU 9 is attached as is to the designated transmission document, and the transmission document is registered in the transmission file.

Note that CCU9 has file numbers from 5CU7.

When receiving the return, the file No sent to 5CU7 is changed to the file N o sent from 5CU7.
o, and re-register.

Next, the transmission processing executed by the system control section 7 and the communication control section 9 will be explained with reference to FIGS. 27 and 28.

The communication control unit (CCU) 9 determines that the transmission is to start when the transmission time is specified, or immediately when the transmission time is not specified, and turns on the transmission status (makes a transmission request). ).

Then, the system control unit (SCU) 7 polls the CCUS at predetermined time intervals to check whether the transmission status has turned ON, and when the transmission status has turned ON, that is, when there is a transmission request, , C.C.T.
File number to be sent to J9, (sending file N
o, ), and when ccvS receives this transmission file number, it sends transmission file N to 5CU7.
o, and waits for a command from 5CU7.

Therefore, 5CU7 determines whether the transmission file No. received from CCU9 is rTDOc-XXXJ or "FDOC-XXX."
J is checked to determine whether the document is to be sent in FAX mode.

At this time, if the transmission file No. is a FAX mode file No., the FA
Sends an X send document command, and if the file number is in the ETEX mode, sends an ETEX send document command.

Therefore, the CCU 9 determines whether the command received from the 5CU 7 is a FAX transmission document command, and
Depending on the result of this determination, line connection processing with the destination (other party) is performed according to the rules of facsimile communication or teletex communication.

Then, when the line with the other party is connected and transmission becomes possible, the transmission document is sent to 5CU7 according to the transmission mode (FAX/ETEX) between 5CU7 and CCU9.
Processes sending and receiving documents to be passed from CCUS to CCUS.

Thereafter, CCUS transmits the transmission document information received from 5CU7 to the destination according to the transmission mode (FAX/ETEX).

Then, the 5CU 7 immediately performs the transmission end process after sending the transmission document to the CCU 9, or when the transmission is not possible.
The CCU 9 immediately performs a transmission termination process after completing the document transmission to the other party, or if the line connection is not possible, and terminates the series of processes.

In this transmission end process, when the other party is a facsimile terminal device, the CCU9 sends a digital identification signal (D ) in the destination list of the destination facsimile terminal.

Here, the process of registering a digital identification signal (DIS) as terminal function information in the destination list will be explained with reference to FIGS. 2S to 31.

First, the facsimile communication procedure will be explained with reference to FIG.

If the calling station has an automatic calling function, the calling station sends out a calling tone (CNG) after connecting the line, and the called station receives this calling signal (CNG) and transmits the called terminal identification signal (CED).
), then sends out a digital identification signal (DIS). In addition, this DIS includes CCITT Recommendations T and 3.
0, the data transmission rate, encoding method,
This includes the receiver's minimum scan line time capability per line, etc.

Therefore, one calling station selected the terminal function (data transmission rate, encoding method, etc.) that matched its own as indicated by this digital identification signal (DIS), and sent out a digital command signal (DO8) indicating the selection. After that, the training check signal (
TCP).

In response to this, the called station receives a training check signal (TCP) using the commanded terminal function, performs training, and returns a reception ready signal (CFR) when the training is successful.

After receiving this reception completion signal (CFR), the calling station transmits image information (data).

Therefore, the system control unit 7 executes the DIS registration process shown in FIG. 30 at the end of the destination list registration process or at the end of transmission to the facsimile terminal device.

Then, when registering the destination list, the facsimile terminal device is specified in mode (mode F is set).
Determine whether there is a terminal device.

If there is a mode F terminal device, DIS is registered as predetermined standard terminal function information for that terminal device (destination).

The terminal functions of this standard include 1, for example, the encoding method, knee-dimensional encoding, data transmission rate: V, 27 ter (2400/
4800bps) Minimum scanning per line nrJ: 2
0m5.

In addition, if it is not when registering the destination list, that is, when the transmission is completed when sending a document to the destination facsimile terminal device, it is written in the digital identification signal (DrS) received from 1 communication control unit (CCU) S. Change.

Here, the format of each destination list in the destination list is 1, for example, [number J] as shown in FIG.

It consists of the following registration areas: "Broadcast", "Destination Name", "Address", "Mode", and rDISJ.

Note that the numbers shown outside the frame in the figure are the maximum number of bytes of each data.

In this way, when registering the destination list, if it is specified that the destination terminal is a facsimile terminal, standard terminal function information is registered as the terminal function information, and when sending to the facsimile terminal, the terminal function information is sent to the other party at the time of transmission. It is rewritten to the terminal function information received from the destination facsimile terminal.

As a result, the first transmission is performed using the standard data transmission rate, encoding method, minimum scanning time per line, etc., but thereafter data transmission speeds, encoding methods, and line speeds are determined according to the functions of the recipient's facsimile terminal. It can be transmitted in the minimum scanning time, etc.

Therefore, in terms of standard terminal functions, many terminals have a function of 96008 PS, so the fill bit (Fill bit)
Even if the number of fill bits increases, the standard minimum scanning time per line at 9600 BPS is sufficient, so many fill bits are transmitted per line, resulting in poor data compression rate and longer communication time. By registering the terminal function information of the destination facsimile terminal, optimal data compression can be performed and communication time can be shortened.

Next, the file server of 5CU7 at the time of this transmission process/<
The functions of 7B and JXFDG7c will be explained.

First, in order to perform data transmission between this file server 7B and JXFDG7C, two system queues, namely JXFDG7G, notify that generation of one page of compressed data (FAX data) has been completed. Queue rPAGEDATAJ and file server/< 7 n KaJ X F D a 7 for that notification.
A queue rJXFDGACKJ is set for responding to c.

The queue rPAGEDATAJ is the FA for one page.
rPAGE D indicating that the generation of X data is complete
ATA READYJ (Page Data Ready) and rFINAL, which indicates that generation of one page of FAX data has been completed and that page is the final page.
PAGE DATAREADYJ (final page data ready).

In addition, for these "Page Data Ready" and "Final Page Data Ready".

Data representing the page number is also added.

Also, the queue rJXFDGACKJ is the FA of CGUS.
"ACK" indicating that the transfer of X data has been completed normally
(Ack) and “Ack” indicating that an error occurred in the transfer.
Used to notify "NACK".

Therefore, the functions of the file server 7B will be explained with reference to FIGS. 32 and 33.

First, when the power is turned on, the file server 7B and JXFD
The above two queues rP for data transmission between G7Cs

These queues are opened by FD07C.

Therefore, the file server 7B generates the aforementioned queues rPAGEDATA'' and rJXFDGACKJ (queues generated by the file server 7B), J
These queues are opened by XFDG7G.

Therefore, as mentioned above, the file server 7B
When the O2 feed equal status is turned on (feed (FJ)
When a request is made), a process not shown in the figure requests the transmission file number from CeO2, checks whether the transmission file number is rFDOc-xx
It is determined whether the mode is AX mode or not, and if it is FAX mode, the subsequent FAX communication processing is executed.

First, JXFD07C is started using the file name received from CeO2 as a parameter. In addition.

Specifically, it is started with P CLI ”JXFDG file name (system control startup JXFDG file name).

As a result, the JXFDG7G starts controlling the process of expanding and compressing the code data of the transmitted document with the specified file name into image data, as described below, and
Compressed data (FAX) is stored in a temporary file configured with DS.
data), and the file name is rFAX data page file F: FAXPGXXX, FAXJ), 1
When the generation of FAX data for one page is completed, "r-page data ready" or "final page data ready" is notified to the file server 7B through the system queue.

On the other hand, the file server 7B uses the system queue r
Leading P A G E D A T A J,
“Ready” from JXFDG7C (“Page Data

) is returned.

In this case, if "Ready" is not returned from JXFDG7C, check whether there is a timeout or not.
If it has not timed out, wait for 1 second and press J again.
Return to the "ready" check process from XFD07G.

If "Ready J (including page number)" is returned from JXFDG7G before the timeout, the temporary file rFAXPGXX corresponding to the page number is
Reads the FAX page data (image information) of X, FAXJ.

After that, the read file name rFAXPGxxx,
Transfer (send) the FAX page data of FAXJ to CGUS, and delete the sent rFAXPGXXX and FAXJ from the temporary file.

Then, it is determined whether or not an error occurred in the transfer of the FAX page data to CeO2, and if no error occurred, that is, if the process ended normally, rAcKJ is sent.
If an error occurs, send rNACKJ to the system queue r
Write to JXFDGACKJ and return to JXFDG7G.

After that, if an error occurs, it will proceed directly to error processing, and if there is no error (if it ends normally), JXFD
It is checked whether the "ready" received from G7C is "final page data ready" to determine whether it is the end.

At this time, if it is the end, the process is immediately terminated, and if it is not the end, it returns to the "ready" check process from JXFDG7C again.

On the other hand, it takes a certain amount of time (
For example, when 60 seconds have elapsed (timeout), the process is terminated as an error.

Next, the interface between the JXFDa7c, DCRiQ, and CRTCU8 will be explained with reference to FIG.

As described above, when this JXFDG 7C is started on the file server 7B, it performs initialization processing prior to actual processing, and then requests the CRTCU 8 for FAX mode (FAX mode request).

At this time, if the CRTCU 9 is currently printing and is using the print memory, it temporarily suspends printing and saves the contents of the print memory (printer page buffer) to a temporary file (comprised of HDDS). process,
When this process is completed, "ready" is notified to JXFDG7C.

Further, it is checked whether DCRi( ) is being used by another process or not, and if it is not being used, DCRIO is reset (DCR reset).

After that, the JXFDG7c reads only the format management data of the document with the specified file name from the transmission file, and generates data for one page (page data) while sequentially reading character data based on this format management data.
Write to printer page buffer of CRTCU8.

Then, when writing of one page worth of character data (code data) to the printer page buffer of CRTCU 9 is completed, a FAX is sent to CRTCU 8.
(Fax) Instructs to start mode.

As a result, the CRTCU 8 uses the image editing data buffer to convert (expand) the nine code data written into the printer page buffer into image data and stores it in the FAX transmission data buffer (image data buffer). When image data for n lines (for example, 16 lines) is generated, this is notified to the JXFDG7C using "data ready".

Therefore, JXFDG7C reads 0942 minutes of image data from the FAX transmission data buffer of CRTCU9 into the internal buffer, and when the reading is completed, the CRTCU
8 is notified by rACKJ that data reading has been completed and the next 0942 minutes of image data can be received.

Then, when the image data is stored in the internal buffer, the JXFDG7G stores the image data (094
2 minutes) to the DCRID buffer (image data area of the shared memory 84 shown in FIG. 10), and the DCRI
A data compression command is sent to O to instruct data compression.

As a result, the DCRIO compresses the image data according to the rules, sequentially stores the compressed data in the compression code area of the shared memory 84, and when the compression of 0942 minutes of image data is completed, it informs the JXFDG7C of "Data Empty". ” to notify that fact.

Therefore, JXFDG7C again writes the image data for 0942 minutes into the image data buffer of the shared memory 84 and instructs DCRi[] to compress the data.

Then, when the image data is converted into compressed data in this way and the compressed code buffer of the shared memory 84 becomes full, DCRlo notifies the JXFD07C of this by "compressed data full."

Therefore, before processing the page, JXFDG7c
A file corresponding to the corresponding page generated on DDS (file name rFAXPGxxx, FAX
Write (save) the compressed data created with DCRIQ to the file J), and when the save is completed, write the
The interface unit notifies DCRIO of this fact using rACKJ.

In this way, when one page's worth of compressed data has accumulated in a file, you can close the file and
As described above, the page data ready (including the page number) is notified to the server 7B through the system queue, and the response (ACK/N) is sent from the file server 7B.
ACK) via the system queue.

If the response from the file server 7B at this time is ACK, the process continues; if the response is NACK, the process ends.

In this way, when the expansion into image data and the compression of the image data up to the last page of the transmitted document are completed, that is, when the compressed data of the last page is saved in a temporary file, the file server 7B is・Notify "Page Data Ready".

Then, when a response is received from the file server 7B, the system queue for task communication with the file server 7B is closed.

Also, if the state before processing of this JXFDG7C is printing for CRTCU8, the data saved in the -time file is reloaded into the print memory of CRTCU8 and the FA
Instructs to end X mode (FAX mode release).

Furthermore, the 0CRIO resource is released so that it can be used for other processing.

Next, CRTCU9 and 5CU7 (JXFDG7G)
The interface between them will be explained.

CRTCU9 transfers the code data written to the printer page buffer from 5CU7 to 5CU7 as described above.
Upon receiving a FAX mode start instruction from (see FIG. 34), the image data is developed into image data and sequentially stored in a FAX transmission data buffer (image data buffer).

The image data is stored in the image data buffer by adding a 2-byte line status as shown in FIG. 35.

The line status indicates the attributes of the line, and the first (1st) byte is the line status.

00■: Indicates no attribute.

01 II: Indicates that all row data is white (off).

80 II: Indicates that the number of lines indicated by the second (2nd) byte below are all white.

E OIt: Indicates end of page (PPE).

When the C-RT CU 3 stores ○ lines (for example, 16 lines) of image data in the image data buffer, it notifies the 5 CU 7 that it is ready and sends the 094
Request to receive 2 minutes of image data.

In this case, the third command from CRTCU 9 to 5CU 7 is
An image data buffer parameter block (IDB-PB) having a format as shown in FIG. 6 is prepared. Note that this IDB-PB is written in the management area of the shared memory.

Offset, segment: Fixed data indicating the address of the image data buffer (e.g. 200on, Coco
H).

Line buffer length: Indicates the length of one line of image data buffer (see Figure 35).

Number of rows: Indicates the number of rows in the image data buffer (see FIG. 35). Note that when one page ends, the most significant bit (MSB) of this number of lines is set to "1".

Next, the interface between 5CU7 (JXFDG7G) and DCRlo will be explained.

First, the types of commands and responses to be used (in the order of symbols, codes, and names) and parameters (in the order of symbols, related commands/responses, and explanations) will be explained.

Command CR5; XXFOH: DCR initialize command (no parameters) CCP; XX20H: Compression start command (with parameters, PTL, r'TM, PBR) CCC; XX30H: Compression continuation command (no parameters) Response R5l3Y; xx30I■: Standby response (No parameter), corresponds to the CRS command.

RERR; XXFOH: Error response (no parameters); in this state, only CRS commands can be accepted.

TDQ: XX2011: Image data request response (no parameters), requests image data for the next compression during compression.

RCDF; XX3011: Compression code full response (
With parameters, PCL, PIQ, PCE).

Requests reading of compressed code during compression.

Parameter PMC; CCP: Indicates the encoding method (-dimensional or two-dimensional).

PIL; CCP: Indicates the number of bytes per line of image data. Store the value directly.

PTM: CCP Indicates the minimum scan line time per two lines. Stores the value directly in units (ms). For example 201I
If it is Is, it becomes "roo14u".

PBR: CCP: Indicates the transmission speed (BPS) of the communication line. Stores the value of direct value/100. For example, transmission speed 96
At 00 baud, it becomes "96".

In addition, the 5CU7 obtains information such as encoding capability, minimum scanning line time capability per line, and data signal speed (transmission speed) from the DTS (digital identification signal) of the destination registered in the destination list at the time of fax transmission (ff). These parameters are read and used to pass the terminal function information of the destination facsimile terminal to DCRIQ.

PCL; RCDF: Indicates the number of bytes of the compressed code sent from the DCR side during compression. Store the value directly.

Note that when the compressed code area is full, PCL=FF
F F II.

PTQ; RCDF; Flag for requesting the next image data. When requesting data, set PTQ=XX00H.

PCE; RCDF: A flag indicating the end of 1 page (1 unit) compression. At the end of compression, PCE= x
x o o ii.

Next, data compression using DCRlo will be explained.

First, 5CU7 is 0 from CRTCU8 as mentioned above.
It receives 517 minutes of image data and stores it in an internal buffer.1 For example, as shown in FIG. 37 (page end: P
(This is an example including PE) 0517 minutes of image data is
After writing to the image data area of the shared memory 84 of CRlo, it sends a compression start command CCP to DCR. The meaning of line status is the same as the CRTC mentioned above.
The same is true for U8.

On the other hand, DCRlo is 5CU7 as shown in FIG.
When the command from is not the compression start command CCP, other command processing is executed.

When the compression start command CCP is received, the parameter is read to determine whether the encoding method is a one-dimensional encoding method or a two-dimensional encoding method, and if it is a two-dimensional encoding method, the process proceeds to two-dimensional compression processing. If it is a -dimensional encoding method, the process shifts to one-dimensional compression processing described below.

In this -dimensional compression processing, the parameters are first read in processing A, and the position of the line status on the shared memory 84 is calculated from the value of the specified image data length. The fill (FILE,) bit length is calculated from the transmission rate.

After that, read the line status (see Figure 37),
Determine whether the parameter is PPE (page end).

At this time, if the parameter is not PPE, it is determined whether all one line is white, that is, whether all lines are the same (XX01H).

If the process is not complete, start the FCP85 in process B and read the run length (RUNLENGT) of the image data.
After detecting H), the run length detected in process C is
Convert to H (-order compression method) code.

At this time, if the FCP 85 detects the i-winter of one line, it codes the length of the filter calculated in process A, and then codes an EOL (end of line) code (000000000001).

Also, if it is a blank line, M of white run (one line) is processed.
Code the H code. Note that if there are multiple lines in all the lines, the outgoing runs are coded for that number of lines.

After processing C or processing is completed, it is determined whether or not the image data is empty, and if the image data is not empty, it is determined whether or not the compression code is full, and if the compression code is not full, the first row Return to the process of reading the line status.

On the other hand, when the image data is empty,
In process E, an image data request response PIDQ is sent to the 5CU7.

Furthermore, when the compressed code is full, a compressed code full response RCDF is sent to the 5CU7 in process F.

At this time, if the image data is empty at the same time, 1
Add a parameter PIQ requesting the next image data.

Then, processing E or processing Ft when image data is empty or compression code is full! :After finishing.

It is determined whether or not the compression continuation command CCC is received from the 5CU7, and when the compression continuation command CCC is received, the process returns to the line status reading process.

In this way, the image data for one page is compressed, and the read line status is the page end PPE.
When 5CU7 is reached, the RTC code (EOLx6) is coded, the number of bytes of the compressed code coded on the shared memory 84 is set to the parameter PCL, and the parameter PCE indicating the end of compression of one page is set. Request for pick-up.

In this way, the compressed code for one page is coded in the compressed code area of the shared memory 84.

An example of the format when the compressed code for one page is coded in the compressed code area of the shared memory 84 in this way is shown in FIG. 3S.

If the compression continuation command CCC is not received from 5CU7 when the image data is empty or the compression code is full, it is determined whether or not the initialization command CR5 has been received, and if it is the initialization command CRC, initialization processing is performed and the initialization is performed. If it is not a command CRC, error processing is performed.

In addition, in this terminal device, the data bit arrangement when the CRTCU9 handles image data, and the DCRlO
The bit arrangement when the FCP 85 handles image data is different.

In other words, when the CRTCtJ9 expands image data onto the internal memory, it expands the image from the MSB (most significant bit) of the data bits, whereas the FCP
85 detects the run length from the LSB (least significant bit) of data during MH encoding.

Therefore, if the run length of the data written from the CRTCU 3 to the shared memory 84 is directly detected by the FCP 85, a run length of data different from the written data will be detected. As shown in , an inverting data gate 86 that inverts the bit arrangement of write data or read data for the shared memory 84 and a non-inverting data gate 87 that does not invert the bit arrangement of the write data or read data for the shared memory 84 are provided. ing.

Therefore, when processing data without changing the bit arrangement, for example, data can be written to the shared memory 84 through the non-inverting data gate 87 when storing data, and data can be read out through the non-inverting data gate 87 when reading data. Bye.

Further, when processing data by changing the bit arrangement, for example, data may be written into the shared memory 84 via the inverted data gate 86 when storing data, and read via the non-inverted data gate 87 when read.

Next, the interface between the 5CU7 and the CCU9 will be explained.

As mentioned above, when ccus starts sending, the sending status is set to ONL, while SCU7 sets the sending status to ONL.
l When the status is detected as ON, it requests the transmission file number from CeO2 as shown in Fig. 40, and
File No. from O2.

If the file No. is in FAX mode, CeO2 sends a FAX send document command, and when the line connection is completed, CeO2 sends FAX data by returning an ACK frame. Move to processing.

Then, 5CU7 transfers one page's worth of image information (FAX page data) to CeO2, and when CeO2 completes receiving the image information, it sets a page (PAGE) flag. The process of sending the image information of the last page to CeO2 continues, and the image information of the final page is sent to CeO2.
When sent to 2, CeO2 sets a document end (D○CE) flag.

Therefore, the final response frame is sent from the 5CU 7, and this FAX mode processing is ended.

Note that CeO2 returns a final response frame instead of an ACK frame when line connection with 5CU7 is not possible, and returns a file (instead of a page flag or document end flag) when an error occurs during line connection. FAIL) flag is returned.

Further, an example of the format of image information between this 5CU7 and CeO2 (in the case of -dimensional encoding) is shown in FIG. 41.

This image information includes EOL (end of line) for synchronization and FAX message (compressed code).

FILL C) and RTC (EOLX6).

It consists of a page end (OOII X n + F F H) and page information (MPS/EOP).

The number n of ro OHJs at the end of the page is set to be greater than the number of roOJIJs that appear consecutively in the FAX message, for example, 24. Further, MPS of the page information indicates that the next page exists, and EOP indicates the end of the page.

CeO2 transmits the image information of the transmission document thus sent from 5CU7 to the other party according to the facsimile transmission procedure.

In this way, this document creation communication terminal device expands the code data of the transmitted document into image data, and compresses the expanded image data.

Since it has a function to send documents to other parties, it is also possible to send documents by facsimile.

At the same time, when the fax mode is set when the destination list is We, standard terminal function information is registered in the destination list, and the terminal function information sent from the destination fax machine when sending a document to that destination. Rewrite the terminal function information in the destination list. In other words, since the digital identification signal (DIS) of the recipient is registered in advance from the second time onwards, data can be compressed appropriately according to the capabilities of the recipient's facsimile at the time of transmission, thereby reducing communication time. can be achieved.

In other words, 1. In a normal facsimile machine, prior to transmission, information on the terminal function of the receiving side is known, and then the transmission document is scanned and transmitted.

On the other hand, a document (character code) created with a Nihonkai word processor, like a document creation communication terminal device, is converted into a dot image using a CG (character generator), encoded through DCR, and sent to a facsimile terminal device. When sending (-=), it is difficult to perform processing such as data compression in real time after knowing the terminal functions of the destination facsimile terminal, such as a facsimile terminal. J! that the terminal device may have. It is necessary to start processing such as data compression using an r4-like function and also to place a call to the destination facsimile terminal.

Therefore, like this document creation communication terminal device, the terminal function information of the other party's facsimile terminal device is written to the W82 in advance.
By doing so, it becomes possible to perform data compression processing, etc. that is appropriate for the terminal functions of the destination facsimile terminal device.

In addition, in the above embodiment, when registering the destination list, f3
By registering the terminal function information corresponding to the destination, it is possible to send a message to the terminal function information received when actually sending a document. If you register this received terminal function information,
From the time of first sending a document, etc., it is possible to send it according to the terminal function of the other party.

In addition, although the above embodiment describes an example in which only a document is sent, in addition to this, the terminal identification information (TID) of the calling party is
It is also possible to send the calling party's private terminal identification information (name, etc.) and messages (comments, etc.) as fax data.

Effects As described above, according to the present invention, documents can also be sent to a facsimile machine, and can be sent depending on the capabilities of the destination facsimile machine.
