The present invention relates to a document producing apparatus capable of transmitting a created document to a facsimile apparatus and receiving a transmission signal from the facsimile apparatus.

An apparatus for transmitting a document created by a document creating apparatus (word processor) to a facsimile apparatus is disclosed, for example, in Japanese Patent Publication No. 62-59505. The device disclosed in the above publication is composed of a document writing device and a facsimile terminal. In the above-mentioned device, the document creating device expands the character data into the image data (image pattern data), and sequentially cuts out the developed image data by a predetermined number of feet in the vertical direction (dot direction of the print head) and transmits it to the facsimile terminal. The facsimile terminal stores image data of one row of documents in a buffer memory, cuts out the image data in this buffer memory in the horizontal direction, and transmits the image data to the other side facsimile apparatus.

In such a device, the facsimile terminal must cut, encode, compress, and transmit the image data in the horizontal direction. As a result, the burden on the facsimile terminal is high and the transmission rate is lowered.

An object of the present invention is to provide a document creating apparatus having a facsimile transmission function capable of facilitating the transmission of document data.

In order to achieve the above object, the document creating apparatus according to the present invention comprises: document creating means (1) for creating a document; An adapter means (3) connected to the document creating means, configured to be operable in parallel with the document producing means, and for facsimile transmitting a document created by the document producing means; It consists of.

With the above configuration, the document creation means and the adapter means operate in parallel, so that the data can be faxed efficiently and the transmission rate can be improved.

Next, a document creating apparatus according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the document creating apparatus according to this embodiment includes an adapter which is freely attached and detachably attached to the host system (document writing apparatus main body) 1 and the host system 1 through a connector C or the like. 3) consists of.

The host system 1 includes an internal bus 11; Keyboard 12; A ROM 13 in which a program for creating and modifying a document, a program for facsimile transmission and reception of a document according to the present invention, and the like are stored; A CPU (central processing unit) 14; External storage device (FDD) 16 in the first embodiment; floppy disk controller (FDC) 15; buffer circuit 19; serial printer 18; printer interface 17; A display 24 and an interface 20.

The keyboard 12 is connected to the internal bus 11, and information such as character codes and various commands are input from the keyboard 12. The ROM 13 is connected to the internal bus 11 and is read out by the program instruction CPU 14 stored in the ROM 13 and executed. The CPU 14 stores, in the document buffer 21, document information consisting of a character code input from the keyboard 12 and a control code (Cine feed page code, tab code, and the like). The CPU 14 also executes other programs stored in the ROM 13 to control document creation operations, printing operations, facsimile transmission and reception operations, and the like. The FDD 16 stores documents and the like. The floppy disk controller 15 is connected to the FDD 16 and the internal bus 11 to control the FDD 16. The serial printer 18 prints characters and the like. The buffer circuit 19 is connected to the internal bus 11. The buffer circuit 19 includes a document buffer 21; A line buffer 22; It is composed of a work buffer 23.

The document buffer 21 stores the created document and the document information read out from the FDD 16. The CPU 14 reads the character code from the document buffer 21 and accesses a font ROM (25) in which the dot pattern of the character is stored according to the character code. Then, the CPU 14 reads out the dot pattern from the font ROM 25 to the character code and stores it in the buffer 22. The character code is appended with attribute information such as subscript and enlargement of superscript characters. When the CPU 14 stores the dot pattern in the line buffer 22, the CPU (14) refers to these attribute information.

The line buffer 22 is a kind of bitmap memory and stores bit data that can be printed by one scan of the printing head of the serial printer 18.

In this embodiment, the character pattern is represented by 24 dots (bits) each vertically. The line buffer 22 has a capacity of 3 bytes (24 bits) in the vertical direction and 1536 bits in the horizontal direction, as shown in FIG. The work buffer 23 stores an image pattern for fax terminal transmission. The work buffer 23 has a double capacity of the line buffer 23, that is, 6 bytes (48 bits) in the vertical direction and 1536 bits in the horizontal direction. The printer interface 17 is connected to the printer 18 and the internal bus 11. The display 24 is connected to the bus 11 to display operation menus, documents, cursors, and the like.

The interface 31 is connected to the interface 20 to control the transfer of data between the interface 20 and the interface 20. The internal bus 32 is connected to the interface 31 to transmit data. The CPU 33 is connected to the internal bus 32, operates according to a predetermined program, and controls a facsimile transmission and reception operation.

The buffer circuit 34 is connected to the internal bus 32, and the buffer memory 39; A code (CO / DEC) buffer 40; Modem buffer 41; It consists of. The code / decode circuit 35 is connected to the internal bus 32 to code an image to be transmitted and to decode the received facsimile data. The I / O memory 36 is connected to the code / decode circuit 35 to time-code data to be coded or decoded. The transmission circuit 37 is connected to the internal bus 32 and the communication (facsimile) line 38 to control the transfer of data.

Next, the operation of the configuration shown in FIG. 1 will be described.

(a) Document writing operation

Based on the input from the keyboard 12, the CPU 14 creates a document under the control of a program stored in the ROM 13. 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, the document buffer 21 stores the character code, attribute code, and control code in the format as shown in FIG. When the character is modified, such as # 2 in the second line of the document in FIG. 3, the head address of the storage area in which the attribute code indicating the modified content of the character and the detailed information about the expression are stored is stored in the document memory. do.

In the case of Fig. 4, a code and an address SO indicating the expression of a subscript character designation are set in the second character of the second line. In the storage area of the head address SO, it is stored that the lower designated character is # 2. In other areas of the document memory, data LP indicating line pitch at the time of printing by the printer 18, data CP indicating character pitch, data indicating the size of characters not shown, data indicating the number of lines per page, 1 Data indicating the number of characters per line is stored. On the other hand, depending on the contents of the document buffer 21, the document being created or created is displayed on the screen of the display device 24.

(b) Document preservation operation

In response to the key operation for supporting the storage of the document, the CPU 14 supplies the document held in the document buffer 21 to the FDC 15. The FDC 15 controls the FDD 16 to store the document on the floppy disk. A table in which a file name and a storage address are registered is created for each document, and a file name can be designated to introduce a corresponding document into the document buffer 21 in the FDD 16.

(c) printing operation

In this embodiment, the document stored in the document buffer 21 is printed. If the document to be printed is stored in a floppy disk or the like, printing is performed after transferring the document from the floppy disk to the document buffer 21.

When printing, the CPU 14 creates a table indicating the X position, the Y position, and the zone number for each character in each line before printing each line of the document held in the document buffer 21. do. The X position represents the position of each character in the X direction (moving direction of the print head). The Y position indicates the position of each character in the Y direction (feed direction of the paper). In the case of printing a character whose size is larger than the vertical dote number of 24 dots of the line buffer 22, the entire character cannot be printed by one scan of the printing head, and the character is divided into several zones. You must print by scanning. The zone number indicates which zone of the current character pattern is being printed. For example, when printing the first row "ABCD" in FIG. 3, as shown in FIG. 6A, the distance X _1- X ₄ from the end of the sheet to the end of each character is set in the table positioning area. ; Since the positions of the characters “ABCD” in the Y direction are the same, data 0 is stored in all the Y position areas; Since the size of the character "ABCD" is a normal size of 24 dots in the vertical direction, data 0 is set in the zone number area.

Similarly, when printing the second row ＂X ₂ Y＂, as shown in FIG. 6, X _1- X ₄ are set in the X position area of the table; Data 0 is set in the zone number area. Since the letter # 2 is located below the distance n from the letters X and Y, the data #OnO \ is set in the positioning area as shown in FIG. 6B.

In printing each line, the CPU 14 accesses the font ROM 25 according to the table and stores the image data printed in one scan of the printing head in the line buffer 22. That is, the CPU 14 accesses the font ROM 25 based on the character codes in the table, reads out the dot pattern of each character per column (8 dots X ₃ ), and stores it in the line buffer. do. Since the CPU 14 prints characters with the serial printer 18, the contents of the line buffer are cut out in the vertical direction and sequentially supplied to the print interface 17.

When the printer 18 prints a line containing different characters at the Y position, the characters at the Y positions are printed at the same time, and the characters at different Y positions are fed after the paper is fed to the position. For example, when printing the second line #X ₂ Y \ in FIG. 3, the CPU 14 first prints only the characters (X and Y) whose Y position is "0". Next, the CPU 14 feeds the sheet by length n, and prints the character # 2 'whose Y position is n. The printing method using such a table is described, for example, with reference to FIGS. 12, 13 and 14 of US Pat. No. 4,655,622. When printing is finished, the CPU 14 sets data indicating the end date of printing in the printing column of the document list shown in FIG.

(d) Transmission operation

When the document created by the document creating device is transmitted to the facsimile device, the host system 1 and the adapter 3 operate in parallel.

a) First, the operation of the main body apparatus 1 will be described with reference to FIGS.

In response to a key operation for instructing transmission, the transmission operation is executed in the following order. When the document to be transmitted is held on the floppy disk, the FDC 15 and the FDD 16 are controlled to read desired document information from the floppy disk. The CPU 14 stores the read document in the document buffer 21. The document to be sent by facsimile may be a document being created (stored in the door server 21). Next, the CPU 14 performs data processing of Figs. 7A and 7B. First, the CPU 14 sets an initial value (value 0 in this embodiment) in the newline pointer register P, the accumulated line number register Pa, the register Pb, the register Pc, and the accumulated line feed register TLF (step S1), and the CPU 14 Checks the contents of the document buffer 21 and checks whether or not the character data exists in the line to be developed in the image data (step S2). If no character data exists in the target line (for example, only a newline code exists), the control proceeds to step S5 described later. If character data exists in the line to be developed, the CPU 14 accesses the font ROM 25 as in printing, and expands it into image (pattern) data. This developing operation is performed line by line based on the printing table (as shown in FIG. 6A and 6B conductor) as in printing.

The CPU 14 stores the obtained image data in the line buffer 22 (step S3). The operation up to the development of the image data to be transmitted to the line buffer 22 is performed in the same manner as the operation to develop the image data to be printed on the line buffer 22.

Therefore, a program sequence for storing the image data in the line buffer due to the printing can be partially used to obtain the image data to be transmitted.

If the line buffer 22 stores the image data for one scan of the printing head, the control proceeds to step S4. In step S4, the CPU 14 reads out image data stored in the line buffer 22 by a predetermined number of bits in the horizontal direction. Here, the horizontal direction is a scanning direction of the facsimile apparatus. The CPU 14 records and records the cut out image data with data already stored in sequence in the line indicated by the holding value of the newline point P of the work buffer 23.

In this apparatus, part of a document printing program sequence is shared in the facsimile transmission of a document. Therefore, when characters or character strings having different Y positions (shown in FIG. 6B) exist in one row, as shown in FIGS. 9A and 9B, the image pattern of one row is divided into a plurality of circuits and the line buffer ( 22). In the facsimile transmission, if the image pattern shown in Fig. 9a is transmitted after the image pattern shown in Fig. 9a is transmitted, the receiving side attempts to transmit the image pattern shown in Fig. 9b. It does not become the image shown in 9c. Specifically, the CPU 14 first cuts out the byte data EO of the first line of the line buffer 22 shown in FIG. The CPU 14 records and records the cut out image data at the head address (byte number 0) of the line indicated by the newline pointer P of the work buffer 23, and the data and the words already stored at the address. Next, the CPU 14 reads the byte data E1 from the line buffer 22, and takes out and records the data and the words stored at the second address of the first line of the work buffer 23. The same operation is performed for the byte data E2, E3... Is repeated for. After the writing operation to the work buffer 23 is finished, the CPU 14 saves the holding value P of the newline pointer to the register Pc (step S3).

In step S5, the CPU 14 checks whether line feed is necessary (i.e., a character or character string in which the development of the pattern is not finished or a line break exists with reference to the Y position data in the table shown in Figs. 6A or 6B). Check the existence of code). If line feed is not requested (in the case of a complete overlapping stroke or the like), the control returns to step S2. If there is a newline code, the control proceeds to step S6.

In step S6, the CPU 14 saves the cumulative (scan) line count of the facsimile paper stored in the cumulative line number register Pa to the register Pb. The CPU 14 draws in the line feed amount LF (step S7). For example, when the pattern of the lower characters is stored in the work buffer 23, the line feed amount LF is a small non-zero amount in the Y position data in the table 6a or 6b. In the case of a line break to the next line, the line feed amount LF is the sum of the line feed amounts executed to store all the character patterns of the current line in the line buffer LP (shown in FIG. 4) in the work buffer 23. Minus The CPU 14 adds the current line feed amount LF to the accumulated line feed amount stored in the accumulated line feed amount register TLF to obtain a new accumulated line feed amount (step S8). The cumulative line feed amount is a value indicating how far the generation of the dot image of the page to be transmitted has been completed, and the value of the minimum paper feed pitch in the printer 18 described above as a single step. The CPU 14 converts the obtained accumulated newline amount into the number of scan lines of the facsimile apparatus.

The CPU 14 sets the obtained number of scan lines to the pointer Pa (step S9). The CPU 14 adds the increment Pa-Pb of the accumulated line number to the holding value of the newline pointer P (step S10). The CPU 14 has no character pattern on the work buffer 23, and the newline pointer. It is checked whether the holding value of P is non-zero (step S11). If there is no character pattern and the holding value of the newline pointer is not zero, the procedure goes to step S12. In step S12, the CPU 14 sends the holding value of the newline pointer P to the adapter 3 in the form of code data or a command with the number of blank lines.

The CPU 14 checks whether or not the transfer of all the rows in one document page has been completed (step S13). If it is not finished, the control returns to step S2 to execute the same operation for the next row of documents held in the document buffer 21.

On the other hand, in step S11, when NO, that is, when there is a character pattern in the work buffer 23 or when the holding value of the newline pointer P is "0", the control proceeds to step S14. In step S14, the CPU 14 checks whether the holding value of the newline pointer P is 24 or more.

When the holding value of the newline pointer P is less than 24 (23 or less), it indicates that there are other patterns to be synthesized on the work buffer 23 (for example, the pattern of the lower characters), and the control jumps to step S13. . When the holding value of the newline pointer P is 24 or more, it indicates that all the patterns to be transmitted have already been stored up to the line designated by the newline pointer P in the work buffer 23, and the CPU 14 executes step S15. It is checked whether the number of newline lines Pa-Pb is 24 or more (step S15). When the number of newline lines (Pa-Pb) is 24 or more, the controller proceeds to step S16 with the CPU 14 moving the image data for 24 lines in the horizontal direction (scanning direction of the facsimile apparatus) in the line indicated by the value of the register Pc. It reads out and transmits to the adapter 3 (step S16).

The CPU 14 transfers the number of newline lines [(Pa-Pb) -24] to the adapter 3 echo command (or code data) as the number of blank lines (step S17). The CPU 14 clears the contents of the line buffer 22 (step S18) and resets the newline pointer P (step S19). The process proceeds to step S13.

In step S15, when it is determined that a-Pb is less than 24, for example, in a new line, the control proceeds to step S20, and the CPU 14 cuts out the data for the first 24 lines of the work buffer 23 in the horizontal direction and adapts the adapter. (3), 24 is subtracted from the holding value of the newline pointer P (step S21), and the line buffer 22 is updated (the contents of the line buffer 22 are tightened for 24 rows) (step S22). Control proceeds to step S13. The operation shown in the flowcharts of FIGS. 7A and 7B will be described in detail by taking an example of transmitting the document shown in FIG. 3 to the facsimile apparatus on the other side.

Before transmitting any page, in step S13, " 0 " is set in the registers, P, Pa, Pb, Pc, and TLF. Since the character data "ABCD" exists in the first line, the control advances from step S2 to step S3. The CPU 14 creates the table in FIG. 6A and stores the image data of the character " ABCD " in the line buffer 22. FIG. Next, the CPU 14 reads the image pattern in the line buffer 22 in the horizontal direction and writes it to the work buffer 22 (step S4). As a result, the image data of the character "ABCD" is held in the work buffer 23.

The holding value 0 of the newline pointer register P is stored in the register Pc. The character pattern of the first line is all stored in the work buffer 23, and since the newline to the next line is indicated by the newline code, the control proceeds to step S6. The holding value 0 of the register Pa is saved in the register Pb, and the CPU 14 draws in the newline amount from the printing routine (step S7).

In the case of FIG. 3, the line breakage amount is LPO (shown in FIG. 4). This newline is added to the value (currently 0) of the register TLF in which the LPO has been held in advance, and a new cumulative newline is obtained (step S8). Since the minimum paper feed amount of the printer 18 is 1/120 inch and the line pitch of the facsimile is 1/180 inch, the CPU 14 is 180/120 (= 3/2) in the cumulative line feed (unit inch). Multiply by to convert the cumulative line breakage into the number of scan lines of the facsimile apparatus and set it to the pointer Pa (step S9).

The CPU 14 obtains the number of scan lines Pa-Pb corresponding to the newline amount LF and adds it to the holding value 0 of the newline pointer register P. Assuming that the newline amount LF corresponds to, for example, the number of scan lines 30, the holding value of the newline pointer P is 30. Since the character pattern \ ABCD \ is present in the work buffer 23, the holding value of the pointer register P is 30, and the number of newline lines (Pa-Pb) is 30, the control proceeds to steps S16 through steps S11, S14, and S15. Goes. Image data for 24 lines from the holding value 0 of the register Pc, i.e., data representing the character " ABCD " is read out line by line from the work buffer 23 and transferred to the adapter 3 (step S16). The difference 6 between the number of newline (Pa-Pb) = 30 and 24 is transmitted to the adapter 3 as an instruction as the number of blank lines (step S17). The contents of the line buffer 22 are erased (step S18), and the value 0 is set in the newline pointer register P (step S20).

Next, the transmission operation for the second row X ₂ Y is started. First, in step S _2, the presence of the character is detected, and is written by the table illustrated in FIG. 6b at step S _3. Based on this table, the CPU 14 stores, in the line buffer 22, image data of the characters " X " and " Y " Since the holding value of the newline pointer register P is " 0 ", the CPU 14 writes the pattern " XY " from the 0th line to the 23rd line of the work buffer 23, and sets the holding value 0 of the newline pointer register P to the register Pc. Save to (step S4). As shown in Fig. 3, since there is a newline between XXY and X2, the control proceeds to Step S6. The accumulated number of lines 30 held in the register Pa is saved in the register Pb (step S6). Newline amount n is drawn from the table (step S7). A new accumulated new line amount TLF + n is obtained and stored in the register TLF (step S8).

At this time, the line feed pitch to the next line is changed to (LPO-n). The cumulative opening amount (TLF + n) is converted into the number of scan lines of the facsimile apparatus, and the converted number of lines is set to the pointer Pa (step S9). If the cumulative number of lines is assumed to be 42, the increment Pa-Pb of the cumulative line number is 12, and the holding value of the newline pointer register P is 12 (step S10). Since the character pattern exists in the work buffer 23, the control advances from step S11 to step S14. The holding value of the newline pointer register P is 12, and the control jumps from step S14 to step S13, and returns to step S2. In step S2, it is detected that character data # 2 is left, and in step S3, # 2 is developed in the line buffer 22 as shown in FIG. 9B (step S3). The holding value of the newline pointer register P is 12. The image data of the line buffer 22 is ORed with the data of the 12th through 35th lines of the work buffer 23, and is recorded in the work buffer 23. As a result, as shown in FIG. 9C, the image data of the characters 'X ₂ Y' is held in the work buffer 23.

The holding value 12 of the newline pointer register P is stored in the register Pc (step S4). Since there is a newline after the second row, the control proceeds to step S6. The cumulative line number 42 held in the cumulative newline pointer Pa is saved in the pointer Pb (step S6), and the newline amount is stored (step S7). Here, n is subtracted from each Y position data (non-zero) in FIG. 6B.

Then, all of the CPUs 14 check whether the Y position data of the character code is 0 or not, and when all the Y position data is 0, it determines that the storage of all the character patterns of the second row in the work buffer 22 is finished. Then, the CPU performs the newline processing to the next line according to the newline code of the second line.

As described above, the opening amount in this case is LPO-n. The newest running amount LPO-n is added to the cumulative running amount TLF + n, and a new cumulative running amount 2.LPO is obtained (step S8). The CPU 14 converts the cumulative opening amount 2.LPO into the number of scan lines, and sets the obtained number of lines in the register Pa (step S9). The increase in the number of accumulated lines (assuming 18) is added to the holding value of the newline pointer register P, and the holding value of the newline pointer register P is 30. Since the character pattern exists in the work buffer 23, the control proceeds to step S14. Since the holding value of the newline pointer register P is 30 and the number of newline lines Pa-Pb is 18, the control proceeds to step S20. In step S20, image data for 24 lines is transmitted to the adapter 3. 24 is subtracted from the holding value of the newline pointer register P to 6 (step S21), and the contents of the work buffer 23 are filled over 24 lines (step S22).

The control proceeds to step S13, and since the document is not finished, the control returns to step S2, and the above operation is repeated for the character " EFG "

b) Receiving the data from the work buffer 23, the adapter 3 performs operations such as encoding, compression, transmission, and the like described below.

The CPU 33 reads out the data line by line from the work buffer 23 and stores the image data transmitted from the host system 1 through the interface 31 once in the buffer 39. 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 I / O memory 36. The code / decode circuit 35 reads out image data stored in the I / O memory 36 and transfers it to the code / decode buffer 40. When the code / decode circuit 35 transmits the image data to the code / decode buffer 40, the code / decode circuit 35 encodes and compresses the image data according to a known encoding and compression method, for example, the MH mode of the facsimile.

As a result, data for facsimile transmission is held in the code / non-code buffer 40. The compressed data in the code / decode buffer 40 is transmitted to the modem butter 41. The transmission circuit 37 reads out data from the modem buffer 41 and outputs it to the communication circuit 38.

In steps S12 and S17 of FIGS. 7A and 7B, the blank portion of the document is not expanded once to a blank image and expanded in the form of image data, and a command indicating the number of blank lines is transmitted to the adapter 3. In this case, when the CPU 33 of the adapter 3 receives a command indicating the number of blank lines from the host system 1, the CPU 33 uses n lines of blank image data (# 0 data) based on this command. Columns) are stored in the buffer 39 following other pattern data.

While the CPU 33 expands this command to blank image data and transmits it, the host CPU 14 exchanges image data of the next line and stores it in the work buffer 23. In this manner, the processes of the host system 1 and the adapter 3 are repeated in parallel. At the end of the processing for one row of pages, a command for end of page is sent from the CPU 14 to the CPU 33, and the CPU 33 notifies the facsimile apparatus of the termination of the first term transmission.

When the transmission of the entire document is finished, the CPU 14 indicates, in the facsimile transmission column of the table of FIG. 5 installed in the memory 19, a status indicating that transmission is normally completed or an error occurred during transmission and the type of error. Set the status (error code). The occurrence of the error is transmitted from the CPU 33 to the CPU 14, and the CPU 14 generates an internal state error code of the system 1 at that time.

(e) Receive operation

Data sent from the facsimile apparatus to the transmission circuit 37 via the communication circuit 38 is stored in the modem buffer 41.

Data in the modem buffer 41 is transmitted to the code / decode buffer 40. Data in the code / decode buffer 40 is transferred to the I / O memory 36 and the buffer 39. The I / O memory 36 and the buffer 39 have a FIFO structure. The CPU 33 decrypts the data transmitted to the I / O memory 36 and checks whether or not the line end information exists. The CPU 33 monitors the time of the communication line 38 when the line end information is obtained. If there is no reception of the data for a predetermined time, the CPU 33 determines that the reception is completed. The maintenance data of the next I / O memory 36 from which the line end information is obtained is discarded because it is unnecessary.

The data transmitted to the buffer 39 is sent to the host system 1 via the internal bus 32 and the interface 31. In the host system 1, the image data transmitted from the adapter 3 is stored in the work buffer 23. When the amount of information stored in the work buffer 23 reaches a certain value, the CPU 14 sequentially transmits the contents of the work buffer 23 to the FDC 15. The FDC 15 controls the FDD 16 to be coded on a floppy disk or the like to store data in a compressed state. The CPU 14 seeks the magnetic head of the FDD 16 to the open area of the floppy disk before the start of reception. This is to shorten the access time of the FDD 16.

When the CPU 14 stores the received data in the FDD 16, it is necessary to attach a file name to the received document. Thus, in this embodiment, the CPU 14 automatically executes the file names FAXO1, FAXO2 ... in order of receipt of the facsimile data. To the receiving document. The CPU 14 also forms the fax data directory shown in FIG. 10 on a floppy disk or the like. The fax data directory contains the file name and the head address of the storage area where the file is attached, the resolution of the received document (normal and fine mode), bits indicating whether the received document is printed, and the phone number of the other station. And an entry for holding an error code or the like. Each time the CPU 14 receives a new document, it adds data about the received document to this directory.

(f) Printing of received data

When printing a received document, the operator specifies the document name of the document. In response to the specification of the document name, the CPU 14 refers to the fax data directory and reads out the data of this document in the compressed state from the FDD 16.

The CPU 14 includes a decode routine of facsimile data, decodes the data read out from the FDD 16, decodes the data, and converts the image data into image data. The CPU 14 stores the obtained image data in the line buffer 22. When data that can be printed in one scan of the printing head is stored in the line buffer 22, the data in the line buffer 22 is given to the printing head of the printer 18 in units of 24 bits (3 bytes) in the longitudinal direction, and the printer 18 ) Prints the pattern data in the line buffer 22. The above operation is repeated, and the received document is printed. When the printing is finished, the CPU 14 sets a flag indicating a printed file in the printed / unfilled column of the directory of FIG.

(g) Print Document List

If the parameters of the list of documents stored in the FDD 16 are specified, the CPU 14 searches the directory shown in FIG. 10 and causes the printer 18 to print the list of stored documents. In addition to the document name, the status (resolution, printed / unprinted error code), and the like may also be printed. The display of the document list by the display unit 24 is also possible. It is also possible to print a list of documents created by a conventional word processor and a fax received document.

(h) dial operation

You can also use the automatic dial system for fax transmission. An example of this automatic dial system will be described with reference to FIGS. 11A and 11B. The host system 1 includes, for example, a table shown in FIG. 11A on a floppy disk. Each entry in this table holds a group name and a head address of a storage area in which detailed information about the group is held. In each storage area, as shown in Fig. 11B, the partner name, the telephone number, and the status belonging to the group are kept (if transmission to the other party is completed or an error occurs during transmission).

In the case of automatic call-out, the operator causes four groups to be displayed on the display unit by a predetermined key operation. The operator selects with the cursor the group to which the sender belongs. The CPU 14 reads out and displays the name of the destination belonging to the selected group in the storage area corresponding to the selected group. The operator selects the name of the desired destination with the cursor. The CPU 14 reads out the telephone number of the selected counterpart and notifies the adapter 3. The adapter 3 makes an automatic dial based on the notified telephone number. It is also possible to automatically fax the same document to all parties in a group. In this case, the operator instructs transmission by specifying the group to be transmitted and the document to be transmitted. The CPU 14, in response to the instruction, dials the destination belonging to this group in order and transmits the indicated document.

The CPU 14 indicates an error code indicating that the transmission is normally completed at the entry for status maintenance shown in FIG. 11B, an interruption caused by an error occurs during transmission, and the type of error each time the document is faxed to any transmission line. The facsimile apparatus on the other side sets a message indicating that the communication line is not connected. The list of destinations shown in Figs. 11A and 11B may be printed. In the above embodiment, the documents transmitted in the FDD 16 and the document buffer 21 remain even after the transmission operation ends.

In the present invention, the present invention is not limited to this, and the CPU 14 may be configured to delete the document file in the main body 1 after transferring the document from the main body 1 to the adapter 3.

In the above embodiment, the document is filed in an external memory device in the form of a character code and a control code. However, the document is not limited to this, and image pattern data may be held. In addition, the operator may select the format of the character code and control code and the format based on the image data.

In general, printers of word processors can print images on both sides of the paper. On the other hand, since the facsimile apparatus has a different scanning method, it can print up to both side limits of the paper. For this reason, if the image received by the facsimile apparatus is simply printed by the printer 18, both sides of the received image may not be printed. In order to avoid such a problem, the received image may be reduced and then printed by the printer 18. The operator may be able to select reduction and non-reduction of the received image.

According to the above embodiment, the image data is developed into a raster scanner image in the host system 1 and transmitted to the adapter 3. As a result, the adapter 3 can concentrate on encoding and compressing the image data, thereby reducing the burden on the adapter 3 and improving the transmission rate. In addition, when the adapter 3 is connected in parallel to devices other than the host system 1, the operation speed is improved, and it is also easy to add a unique operation.

In this invention, the image data of the form actually output by the work buffer 23 is created, this image data is cut out to the horizontal direction, and is transmitted to an adapter. Therefore, when sending the upper attachment character, the lower attachment character, and the like, it becomes easy to control the paper conveyance of the facsimile apparatus on the receiving side. Whenever the holding value of the newline pointer P exceeds a certain value, the contents of the work buffer 23 are transmitted to the adapter 3, and the remaining data is filled in the head direction. For this reason, the capacity of the work buffer is relatively small, and the transmission operation can be performed at least twice the capacity of the line buffer. In the present invention, the document memory 21, the line buffer 22, and the like are used at the time of fax transmission as in the normal document factor operation.

For this reason, part or all of the program, such as a printing routine of a document creation apparatus, can be used as it is.

Printers typically deliver paper at 120 pitches per inch in length. The facsimile device transmits and receives images at 180 lines per inch. Therefore, when the amount of revision of the sheet of the printer apparatus is accurately converted into the number of scan lines of the facsimile apparatus, the remainder after the decimal point is generated. For this reason, if each LF per line feed is converted to the number of scanner lines in the facsimile apparatus, the error (sum of fractions below the decimal point) becomes large at the end of the paper, and the transmission image is greatly changed. In the above embodiment, however, the cumulative running amount (the value held in the TLF) is obtained (step S8), and the cumulative running amount is converted into the corresponding number of fax scan lines (step S9). Since the number of scan lines to be line fed is obtained (step S10), the error when converting the amount of line breaks to the number of scan lines can be minimized. In the above embodiment, the case where each character is displayed by 24 dots is assumed, but the present invention is not limited to this, and the characters may be displayed by any number of dots.
