(b) Document creation operation Based on the input from the keyboard 12, the CPU 14
Create a document under the control of a program stored in OM1B. The CPU 14 stores the created document in the document buffer 21 in the form of document data consisting of a combination of character codes, control codes, and the like. For example, when a document (ABCD X2Y EFG) shown in FIG. 3 is created, a sentence Y code, an attribute code, a control code, etc. are stored in the document buffer 21 in the format shown in FIG. When a character is modified, such as "2'°" in the second line of the document in Figure 3, an attribute code indicating the contents of the character modification and detailed information about the modification are stored in the document memory. The first address of the stored storage area is retained.

In the case of FIG. 4, a code address SO indicating modification of subscript designation is set in the second character of the second line. In the storage area of the first address or SO, it is stored that the subscript designated character is "2". Other areas of the document memory include data LP01 indicating the line pitch during printing by the printer 18, data CPO1 indicating the character pitch, data indicating the size of characters (not shown), data indicating the number of lines per vane, Data such as the number of characters per line is stored.

The document being created or created is displayed on the screen of the display device 24 according to the contents stored in the document buffer 21 .

(b) Document storage operation In response to a key operation instructing to save a document, the CPU
], 4 transfers the document held in the document buffer 21 to the FDC.
15. FDC15 controls FDD16,
Save the document to the floppy disk. A table is created for each document in which the file name and storage address are registered, and the corresponding document can be saved to FDD by specifying the file name.
16 to sentence 11 /<puffer2].

(C) Printing Operation In this embodiment, the document held in the document buffer 21 is printed. If the document to be printed is stored on a floppy disk or the like, the document is transferred from the floppy disk to the document buffer 21 and then printed.

During printing, the CPU 4 creates a table indicating the X position, Y position, and zone number of each character in each line before printing each line of the document held in the document buffer 21. The X position indicates the position of each character in the X direction (direction of movement of the printer head).

The Y position indicates the position of each character in the Y direction (paper feeding direction). When printing a character whose vertical size is larger than the 24 dots in the vertical direction of the line buffer 22, it is not possible to print the entire character in one scan of the print head; The image must be printed in several zones and scanned several times.

The zone number indicates which zone of the character pattern is currently being printed. For example, when marking "ABCD" in the first row of FIG. 3, the area for the X position of the table is the distance X from the edge of the paper to the edge of each character, as shown in FIG. 6A. are set, and the positions of the characters "ABCD" in the Y direction are the same, so all Y position areas contain data 0.
is stored, and since the size of the characters "A B CD" is the normal size of 24 dots in the vertical direction, data 0 is set in the zone number area. Similarly, the second line “X2Y
When printing ", X1 to X3 are set in the X position area of the table, and data 0 is set in the zone number area, as shown in FIG. 6B.

Since the character ``P2'' is located a distance n below the characters ``X'' and ``Y'', the first 14 is located in the Y position area.
- Data “0nON” is set as shown in Figure 6B.

When printing each line, the CPU 14 accesses the font ROM 25 according to the table, and stores the image data printed by one scan of the printing head in the line buffer 22. That is, the CPU 14 reads the font ROM 25 based on the character code in the table.
The dot pattern of each character is read out every column (8 dots x 3) and stored in the line buffer 22. In order to print characters with the serial printer 18, the CPU 14 cuts out the contents of the line buffer in the vertical direction and sequentially supplies them to the print interface 17.

When the printer 18 prints a line containing characters at different Y positions, it prints the characters at the same Y position once, and prints the characters at different Y positions at once.
The character at the position is printed after feeding the paper to that Y position. For example, when printing the second line "X 2 Y" in FIG. 3, the CPU 14 first prints the character (X
and Y) only. Next, the CPU] 4 feeds the paper by length n and prints the character "2" whose Y position is n.

For example, the printing method using such a table is
P4. '655,622, e.g. its No. 12.13
．． This will be explained with reference to FIG.

When printing is completed, the CPU 14 sets data indicating that printing has been completed in the print column of the document list shown in FIG.

(d) Sending operation A document created with a document creation device is sent to a facsimile device,
When transferring to another facsimile device, the document creation device main body 1 and the facsimile terminal 3 operate in parallel.

a) First, the operation of the main unit will be explained with reference to FIGS. 1 to 8.

In response to a key operation instructing transmission, a transmission operation is performed in the following steps.

If the document to be transmitted is held on the floppy disk, the FDC 15 controls the FDD 16 to read desired document information from the floppy disk.

= 16- The CPU 14 stores the read document in the document buffer 21. Note that the document to be sent by facsimile may be a document being created (stored in the document buffer 21).

Next, the CPU 14 performs the data processing shown in FIGS. 7A and 7B. First, the CPU 14 includes line feed pointer register P1 cumulative line number register Pa, register Pb register Pc,
The initial value (in this example,
The value 0) is set (step Sl). The CPU 14 checks the contents of the document buffer 21 and checks whether character data exists in the line to be developed into image data (step S2). If character data does not exist in the target line (for example, if only a line feed code exists), control proceeds to step S5, which will be described later. If character data exists in the line to be developed, the CPU 14 accesses the font ROM 25 and develops the character code into image (pattern) data, as in the case of printing. This unfolding operation is performed on the printing table (6th A) in the same way as when printing.
, shown in Figure 6B), row by row.

The CPU 14 transfers the obtained image data to the line buffer 22.
(Step S3). The operations until the image data to be transferred are developed into the line buffer 22 are performed in the same way as the operations for developing the image data to be printed into the line buffer 22. Therefore, the program sequence for storing image data in the line buffer 22 for printing can be used in part to obtain the image data to be transferred.

When the image data to be printed in one scan of the printing head is stored in the line buffer 22, the control proceeds to step s4.

In step S4, the C'PU 14 reads out the image data stored in the line buffer 22 by a predetermined number of bits in the horizontal direction. Here, the horizontal direction is the scanning direction of the facsimile machine. The CPU 14 writes the extracted image data by ORing it with the already stored data in order from the line indicated by the value held in the line feed pointer register P of the work buffer 23. In this apparatus, part of the document printing program sequence is shared during document facsimile transmission. Therefore, as shown in Figures 9A and 9B, if there are characters or character strings with different Y positions (as shown in Figure 6B) in one line, the image pattern in one line or The data are stored separately in the line buffer 22. However, in facsimile transmission, if the image pattern shown in FIG. 9A is sent and then the image pattern shown in FIG. 9B is sent, the image shown in FIG. 9C cannot be transmitted. . For this reason, it is first necessary to synthesize and store one-line image patterns in the work buffer 23. To explain specifically, first, the CPU
14 is the first line buffer 22 shown in FIG.
Extract the line byte data EO. CPU 1.4
is the starting address (byte N) of the line indicated by the line feed pointer register P of the work buffer 23.
o, O), perform an OR with the data already recorded at that address and write. Next, the CPU 14 reads the hide data E1 from the line buffer 22, performs an OR with the data stored at the second address of the first line of the work buffer 23, and writes the result.

Below, similar operations are performed for hide data E2, E3, etc.
・is repeated for After the write operation to the work buffer 23 is completed, the CPU 14 saves the current value (P) held in the line feed pointer register in the register Pc (step S3).

In step S5, the CPU]4 determines whether line feed is necessary (that is, by referring to the data at the Y position in the table shown in FIG. 6A or FIG. 6B, or a character string exists, or whether a line feed code exists. If no line feed is requested (such as in the case of complete overstrike), control returns to step S2. If a new line code is present, control proceeds to step S6.

In step S6, the CPU 14 registers the cumulative line number register Pa.
The accumulated (scanned) number of facsimile paper lines stored in register pb is saved. CPU14
takes in the line feed mLF (step S7). For example, when storing subscript nokuturns in the work buffer 23, the line feed amount (L F) is set to 0 in the data at the Y position in the table (Figures 6A and 6B). is the smallest value. In addition, in the case of a line feed to the next line, the line feed iLF calculates the amount of line feed executed to store all character patterns of the current line in the work buffer 23 from the line pitch (LPO) (Figure 4). This is the value after subtracting the total. The line feed amount LF is a value based on the minimum value of the paper feed amount in the printer 18.

The CPU 14 adds the current line feed amount LF to the cumulative line feed amount stored in the cumulative line feed amount register TLF to obtain a new cumulative line feed amount (step S8).

The cumulative line feed amount is a value that indicates the generation of a desoto image of the page to be sent, or how far that page has ended.
This is a value in units of the minimum paper feed pitch in the printer 18 described above. The CPU 14 converts the calculated cumulative line feed amount into the number of scan lines of the facsimile machine. C
The PU 14 stores the obtained number of scan lines in the register Pa.
(step S9). The CPU 14 stores the increase in the cumulative number of lines (Pa-Pb) in the line feed pointer register P.
is added to the held value (step 510). The CPU 14 checks whether there is no character pattern on the work buffer 23 and whether the value held in the line feed pointer register P is not 0 (step 511). If there is no character pattern and the value held in the line feed pointer register P is not 0, the flow proceeds to steps 81 and 2. In step S12, C
The PU 14 sends the value held in the line feed pointer register P as the number of blank lines to the facsimile terminal 3 in the form of code data or command.

The CPU 14 checks whether all lines in one page of the document have been transferred (step 813).

If not, control returns to step S2.
, and performs the same operation on the next line of the document held in document buffer 2].

On the other hand, if NO in step Sll, that is, if a character pattern exists in the work buffer 23 or if the value held in the line feed pointer register P is "0", control proceeds to step S14. In step S14, CP
U14 checks whether the value held in the line feed pointer register P is 24 or more. If the value held in the line feed pointer register P is less than 24 (23 or less), this indicates that other patterns (for example, subscript patterns) to be synthesized remain on the work buffer 23.
Control jumps to step 813. If the value held in the line feed pointer register P is 24 or more, this indicates that the pattern to be transmitted has already been completed up to the line specified by the line feed pointer register P in the work buffer 23, and the CPU 14 Step S15
and checks whether the number of line feed lines (Pa-Pb) is 24 or more (step 515). If the number of line feed lines (Pa-Pb) is 24 or more, control proceeds to step S16, where the CPU 14 is the image data for 24 lines in the horizontal direction (
(the scanning direction of the facsimile machine) and sends it to the facsimile terminal 3 (step 516). CPU1
4 transmits the number of line feed lines [(Pa-Pb)-243 as the number of blank lines to the facsimile terminal 3 by a command (or code data) (step 517). CPU14
Clear the contents of the line buffer 22 in step 51.
8), reset the line feed pointer register P (step 519).

Processing proceeds to step 813.

In step S15, the number of line feed lines (Pa-Pb) is 24.
If it is determined that the value is less than 7, the control proceeds to step S20, where the CPU 14 cuts out the image data for the first 24 lines of the work buffer 23 in the horizontal direction and sends it to the facsimile terminal 37, and sets the value held in the line feed pointer register P. 24 is subtracted from (step 521), and the line buffer 22 is updated (the contents of the line buffer 22 are filled by 24 lines) (step 522). Control continues to step 813.

The operations shown in the flowcharts of Figures 7A and 7B are
A case in which the document shown in the figure is transferred to a facsimile machine of the other party will be specifically explained.

Before transmitting any page, in step S1, register P
“0” is set in SPa, Pbs Pc, and TLF. Since the character data "ABCD" exists in the first row, control proceeds from step S2 to step S3. C
The PU 14 creates the table shown in FIG. 6A and stores the image data of the characters "ABCD" in the line buffer 22.

Next, the CPU 14 reads out the image pattern in the line buffer 22 in the horizontal direction and writes it in the work buffer 22 (step S4). As a result, the image data of the characters "ABCD" is held in the work buffer 23. The value 0 held in the line feed pointer register P is saved in the register Pc. All character patterns in the first line are in the work buffer 23
, and a line feed to the next line is instructed by the line feed code, so control proceeds to step S6.

−25= The value 0 held in register Pa is saved in register pb.

The CPU 14 takes in the line feed amount from the print routine (type y 2 S 7 ). In the case of 0 in FIG. 3, the line feed amount is LO. This line feed amount LO is added to the value written in the register TLF (currently 0), and a new cumulative line feed amount is determined (step S8). The minimum page feed amount of the printer 18 is 1/1.20 inch, and the minimum page feed amount of the facsimile machine is 1/180 inch, so the CPU 14 adds 1 to the cumulative line feed amount (unit: inch).
Multiply by 80/120 (3/2), convert the accumulated line feed amount to the number of scan lines of the facsimile machine, and register P
a (step S, 9). The CPU 14 calculates the number of scan lines (Pa-Pb) corresponding to line feed m L O.
is calculated and added to the value 0 held in the line feed pointer register P. Assuming that the line feed amount LO corresponds to, for example, the number of scan lines 30, the value held in the line feed pointer register P will be 30.

Since the character pattern "ABCD" exists in the work buffer 23, the value held in the pointer register P is 30, and the number of line feed lines (Pa-Pb) is 30, the control goes through steps S1], S14, and S15, and then goes to step 81.6. Proceed to. Twenty-four lines of image data from the value 0 held in register Pc, ie, data indicating the characters "Aj3CD", are read line by line from work buffer 23 and transferred to facsimile terminal 3 (step 516). Number of line breaks (
The difference 6 between (Pa-Pb)=30 and 24 is transferred as the number of blank lines to the facsimile terminal 3 by command (step 517). The contents of the line buffer 22 are cleared (step 818), and the value 0 is set in the line feed pointer register P (step 520).

Next, the transmission operation for the second row "X2Y" is started. First, in step S2, the presence of characters is detected, and in step S3, a table shown in FIG. 6B is created. Based on this table, the CPU 14 stores image data of characters "X" and "Y" whose Y position is 0 in the line buffer 22, as shown in FIG. 9A. Since the value held in the line feed pointer register P is °゛0'', CPU1
4 writes the pattern "'X Y" from the 0th line to the 23rd line of the work buffer 23, and saves the value 0 held in the line feed pointer register P to the register E'c (step S4), as shown in FIG. As in, “XY” and “2
”, there is a line break between them, so the control is at step S.
Proceed to step 6. The cumulative number of lines, 30, held in register Pa is saved in register pb (step S6).

Line feed ff1n is imported from the table (step S7)
, a new cumulative line feed amount (TL F + n ) is calculated and stored in register TLF (step S8). At this time, the line feed pitch up to the next line is changed to (LO-n). The accumulated line feed fil (TLF10n) is converted into the number of scan lines of the facsimile machine, and the converted line number is set in the register Pa (step S9). Assuming that the cumulative number of lines is 42, the increase in the cumulative number of lines Pa-
Pb becomes ]2, and the value held in the line feed pointer register P becomes 12 (step 510). Since the character pattern exists in the work buffer 23, control proceeds from step Sll to step S14. The value held in the line feed pointer register P is 12, and the control jumps from step S14 to step 313 and returns to step S2. In step S2, the character data "2"
" is detected, and in step S3, the ninth
As shown in figure B, “2” is the line buffer 22.
(Step S3). The value held in the line feed pointer register P is 12, and the image data in the line buffer 22 is ORed with the data in the 12th to 35th lines of the work buffer 23 and written into the work buffer 23. As a result, as shown in FIG. 9C, the work buffer 2
3 holds the image data of the character "X 2 Y". The value 12 held in the line feed pointer register P is the register Pc.
(step S4). Since there is a line break after the second line, control proceeds to step S6. The cumulative number of lines 42 held in the cumulative line feed amount register Pa is saved in the register pb (step 5S6), and the line feed amount is taken in (step S7). Here, n is subtracted from each Y position data (non-zero) in FIG. 6B (the minimum value is O). Then, the CPU 14 checks whether the Y position data of all character codes is 0 or not.
When all the Y position data are 0, it is determined that all character patterns in the second line have been stored in the work buffer 22. Then, the CPU 14 performs line feed processing to the next line according to the line feed code of the second line. As previously mentioned,
The line feed amount in this case is LO-n. Cumulative line feed amount TLF
The current line feed amount LO-n is added to +n to obtain a new cumulative line feed amount 2·LO (step S8). CPU1
4 converts the cumulative line feed amount 2・LO into the number of scan lines,
The obtained line number is set in register Pa (S9
). The increase in the cumulative number of lines (assumed to be 18) is added to the value held in the line feed register P, and the line feed pointer register P
The retention value of is 30. Since the character pattern is present in the work buffer 23, control returns to step 31.4.
Proceed to. Line feed pointeresis - 30 = The holding value of YuP is 30, and the number of line feed lines Pa - Pb is 18
Therefore, control proceeds to step S20. In step S20, 24 lines of image data are transferred to the adapter 3. 24 from the value held in the line feed pointer register P
The result is 6 (step 521), and the work buffer 2
The contents of 3 are pushed up 24 lines (step 522).
.

The control proceeds to step S1B, and since the document is not finished, the control returns to step S2, and the same operation as described above is repeated for the character "EFG" in the third line "1".

b) Upon receiving the data from the work buffer 23, the facsimile terminal 3 performs operations such as encoding, compression, and transmission as described below.

The CPU 33 reads data line by line from the work buffer 23 and sends it from the document creation device main body 1 to the interface 31.
The image data transferred via the buffer 39 is
-Dan, store.

The CPU 33 transfers the image data stored in the buffer 39 to the code/decode circuit 35. The code/decode circuit 35 stores the transferred data in the 110 memory 36. Code/decode circuit 35 reads image data stored in I10 memory 36 and transfers it to code/decode buffer 40. When the code/decode circuit 35 transfers image data to the code/decode buffer 40,
Encoding image data according to commonly known encoding and compression methods, such as MI (mode) for facsimile transmission,
Compress. As a result, data for facsimile transmission is held in the code/decode buffer 40. code/
Compressed data in decode buffer 40 is transferred to modem buffer 41.

The transmission circuit 37 reads data from the modem buffer 41 and outputs it to the communication line 38.

In steps S12 and S17 in FIGS. 7A and 7B, a command indicating the number of blank lines is transferred to the facsimile terminal 3, instead of once expanding the blank portion of the document into a blank image and expanding it in the form of image data. . When the CPU 33 receives a command indicating the number of blank lines from the document creation device main body 1, the CPU 33 generates 0942 minutes of blank image data (column of O data) based on the command, and stores it in the buffer following other pattern data. Store in three.

CPO33 expands the command into blank image data,
During the transmission, the host CPU 14 converts the character code of the next line into image data and stores it in the work buffer 23. In this way, the processes of the document creation device main body 1 and the facsimile terminal 3 are repeated in parallel. When processing has been completed for all lines on one page, a page end command is sent from the CPU 14 to the CPU 3B, and the CPU 3B notifies the facsimile machine that one page has been sent.

When the transmission of the entire document is completed, the CPU 14 stores the memory 1
In the facsimile transmission column of the table shown in Figure 5 provided in 9, for example, enter the status indicating that the transmission was completed normally, or the status (error code) indicating that an error occurred during transmission and the type of error. set. The occurrence of an error is transmitted from the CPU 33 to the CPU 14,
The CPU 14 generates an error code according to the internal state of the system 1 at that time.

(E) Receiving operation From the facsimile device to the transmission circuit 3 via the communication line 38
7 is stored in the modem buffer 41. Data in modem buffer 41 is transferred to code/decode buffer 40. The data in code/decode buffer 40 is transferred to I10 memory 36 and buffer 39.

The I10 memory 36 and buffer 39 have a FIFO structure. The CPU 33 decodes the data transferred to the I10 memory 36 and checks whether line end information is present. The CPU 3B monitors the time of the communication line 38 when the line end information is obtained. If no data is received for a certain period of time, the CPU 33 determines that the reception has ended. I10 memory 36 after line end information is obtained
The retained data is discarded as it is unnecessary.

The data transferred to the buffer 39 is sent to the document creation device main body 1 via the internal bus 32 and interface 31.

In the document creation device main body 1, image data transmitted from the facsimile terminal 3 is stored in a work buffer 23.

When the amount of information stored in the work buffer 23 reaches a certain value, the CPU 1.4 sequentially transfers the contents of the work buffer 23 to the FDC 15.

FDC], 5 controls the FDD 16 to store encoded and compressed data on a floppy disk or the like. CPU], 4 causes the magnetic head of the FDD roller to seek the open area of the floppy disk before starting reception. This is to shorten the access time of the FDD 16.

When CPU 1.4 stores received data in FDD 16, it is necessary to give a file name to the received document. Therefore, in this embodiment, the CPU 14 automatically names the files FAXOL and FA in the order in which facsimile data is received.
Add XO2... to the received document. Further, the CPU 14 creates a fax data directory shown in FIG. 10 on a floppy disk or the like. This fax data directory contains the file name, the start address of the storage area where the document with that file name is stored, the resolution of the received document (normal mode and fine mode), and the print mode of the received document. It has an entry for holding bits indicating whether or not the communication is being performed, the telephone number of the other party, an error code, etc. CPU
14 adds data regarding the received document to this directory every time a new document is received.

(f) Printing of received data When the operator wishes to print a received document, the operator specifies the document name of the document. In response to the specification of the document name, the CPU
:1.4 refers to the fax data directory,
Read the compressed data of the document from the FDD 16. The CPU 14 includes a facsimile data decoding routine, decodes and decodes the data read from the FDD 6, and converts it into image data. The CPU 14 stores the obtained image data in the line buffer 22. When the line buffer 22 stores enough data to be printed in one scan of the printing head, the data in the line buffer 22 is applied vertically in units of 24 bits (3 hides) to the printing head of the printer 8. [Printer] 8 prints the pattern data in the line buffer 22. The above operations are repeated and the received document is printed.

When the printing is completed, the CPU 14 sets a flag indicating that printing has been completed in the printed/unfinished column of the directory shown in FIG.

(G) Document list printing operation: When an instruction is given to print a list of documents stored in FDD 1.6, the CPU 14 searches the directory shown in FIG. 10 and saves it in printer 8. Print a list of documents. The status (resolution, printed/unprinted, error code), etc. may also be printed together with the document name. It is likewise possible to display a list of documents on the display 24. It is also possible to print a list of documents created with a regular word processor and documents received by Facunmill.

(H) Dial Operation It is also possible to use an automatic dialing system for FAX transmission.

An example of this automatic dialing system will be described with reference to FIG. 1A111B. The document creation device main body 1 includes, for example,
1.1 on the floppy desk. It has the table shown in Figure A. Each entry in this table holds the start address of a storage area that holds a group name and detailed information about that group. As shown in Figure 11B, each storage area contains the name and telephone number of the destination belonging to that group, and the status (such as whether the transmission to the destination was completed or if an error occurred during transmission to the destination). )
or retained.

When making an automatic call, the operator causes the display unit to display four groups by operating a predetermined key. The operator selects the destination or the group to which it belongs with the cursor. C
The PU 14 reads the destination name belonging to the selected group from the storage area corresponding to the selected group,
indicate. The operator selects the desired destination name with the cursor.

The CPU 14 reads out the telephone number of the selected destination name and notifies the facsimile terminal 3 of the telephone number. The facsimile terminal 3 performs automatic dialing based on the notified telephone number.

It is also possible to automatically send the same document by facsimile to all destinations belonging to a certain group.

In this case, the operator specifies the group to be transmitted and the document to be transmitted, and instructs transmission. In response to the instruction, the CPU 14 dials the destinations belonging to the group in order,
Send the indicated document.

Every time a document is sent by facsimile to a certain destination, the CPU 14 enters a status entry in FIG. 11B to indicate that the transmission was completed normally, that an error occurred during transmission, and an error code indicating the type of error. Sets a message indicating that the other party's facsimile machine is not connected to the communication line.

11A, 11. It may also be possible to print the list of destinations shown in Figure B.

In the above embodiment, even after the transmission operation is completed, the FDD 16
And the transmitted document remains in the document buffer 21. This invention is not limited to this, and after transferring a document from the book unit 1 to the facsimile terminal 3, the CPU 14
The configuration may be such that the corresponding document file in the main body 1 is deleted.

In the embodiment described above, documents are filed in the external storage device in the form of character codes and control codes, but the invention is not limited to this, and image pattern data may also be stored.

Furthermore, the operator may be able to select the character code, control code format, and image data format.

Word processor printers generally cannot print images on both sides of the paper. On the other hand, facsimile machines
Because the scanning method is different, it is possible to print to the very edge on both sides of the paper.

Therefore, if an image received by a facsimile device is simply printed by the printer 18, both sides of the received image may not be printed. To avoid this,
It is sufficient to reduce the size of the received image and then print it using the blink 18. The operator may be able to select whether to reduce or not to reduce the received image.

According to the above embodiment, image data is transferred to the document creation device main body 1.
The data is expanded into a rasque scanner image and sent to the facsimile terminal 3. This allows the facsimile terminal 3 to concentrate on encoding, compressing, and transmitting image data, reducing the burden on the facsimile terminal 3 and improving the transmission rate. Furthermore, when the facsimile terminal 3 is connected in parallel to another device other than the document creation device main body 1, the operating speed is improved and it becomes easy to add specific operations.

In this invention, image data in a format to be actually output is created in a work buffer 23, and this image data is cut out in the horizontal direction and transmitted to a facsimile terminal. Therefore, when transmitting upper (=J characters, subscripts, etc.), it becomes easy to control the paper feed of the facsimile machine on the receiving side.

Furthermore, each time the value held in the line feed pointer register P exceeds a certain value, the contents of the work buffer 23 are transmitted to the facsimile terminal 3, and the remaining data is packed toward the beginning. Therefore, the transmission operation can be performed even if the capacity of the work buffer is relatively small (at least twice the capacity of the line buffer). Further, in the present invention, the document memory 21, line buffer 22, etc. are used during facsimile transmission in the same way as in normal document creation operations. Furthermore, the cutting direction of the image data when storing the image data in the line buffer 22 is made the same as the cutting direction of the image data when printing. Therefore, part or all of the program such as the print routine of the document creation device can be used as is.

Word processors typically print at 120 dots per inch, and facsimile machines print at 180 dots per inch.
When printing is done in dots (scan lines), it is impossible to accurately convert the number of line feeds on a sheet of paper into the number of scan lines on a facsimile machine. For this reason, if each line feed amount is converted one by one into the number of scan lines of the facsimile machine, errors will be large at the end of the paper, and the quality of the image will deteriorate. However, in the above embodiment, the cumulative line feed amount of the facsimile machine is calculated (step S8), and the number of scan lines corresponding to the cumulative line feed amount is calculated (step S8).
Since step S9) and the number of increased scan lines are determined (step 510), high print quality can be maintained without the risk of large errors.

In the embodiment described above, it is assumed that each character is displayed in 24 dots, but the present invention is not limited to this, and the characters can be displayed in any dot format. By configuring the two devices to operate in parallel, it is possible to efficiently transfer facsimile data.

According to this invention, document data is cut out in the scanning direction of the facsimile machine and supplied to the facsimile terminal, thereby reducing the burden on the facsimile terminal.

According to this invention, the document creation device main body or the document = 4
3 - By supplying a blank space to a facsimile terminal with a command indicating the number of scan lines corresponding to the blank space,
The burden on the document creation device itself is reduced.
