However, it also takes in key data, instructs the code conversion unit 204 to convert the code, and controls the writing of code data into the input data storage area 202 and the reading thereof.

The input data accumulated in the input data storage area is transferred to the input data discriminator 20B in one interrupt. Here, it is determined whether it is character data or function key data according to the shift and code of the code data.
The determined data is sent to the input mode control unit 20, the full-half-width conversion unit 210, and so on according to the determination result. Roman character conversion unit 212. and is transferred to the function key conversion unit 214, and also transferred to and stored in the code data storage area 21B.

There are basically two types of input modes for this device: hiragana input mode and alphanumeric/symbol input mode. Therefore, there is no katakana input mode, which is explained below.
This is because the input character string corresponding to katakana is converted to katakana when converting the input character string into kana-kanji on a segment-by-segment basis. Regarding the hiragana input mode, there are a kana input method and a romaji input method.

In addition, regarding the size of characters, double-width character input mode,
There is a half-width character input mode. Furthermore, the system default 4 is an insertion mode in which input data is sequentially inserted into the text.

These input modes are controlled by input mode control section 208. The input mode control unit 208 has an input mode information storage area, and has a function of controlling the input mode of the apparatus according to data related to the input mode among the input data.

The function key conversion unit 214 has a function key data storage area, and creates a function key code in response to the data of function keys other than the mode key and full-width/half-width keys, and transfers it to the code data storage area 216 to convert the code. Store in. In this way, the input code data of the keys input from the keyboard 10 is stored in the code data storage area 216.

As shown in FIG. 6, the display unit 24 has three display screens,
That is, the editing screen 500. Guidance display screen 502,
and a layout display screen 504. The overall size of these screens is, for example, 472 dots horizontally and 64 dots vertically.
The dot 0 editing screen 500 can display 17 full-width characters of text and lines, and a character string converted from the input character string to kana-kanji is displayed here, and the user operates the keyboard 10 while looking at this. Editing operations can be performed. In the display example shown in FIG. 7, the character strings "Aiueo" and "Kukeko" are displayed in full-width characters, the character strings "ABCDJ" are displayed in half-width characters, and the character strings "Riki)" are displayed in double-width characters in area 500.

The lower part of the editing screen 500 includes an area 506 where an angle, cursor, scale, etc. are displayed.

The cursor displayed in area 506 moves by the corresponding number of digits according to the attributes of the character at its current position, such as full-width, half-width, double-width, etc. After moving, it occupies the first digit position of the destination character.

The guidance display screen 502 also has a display capacity of 17 full-width characters, and in the normal state, input mode, current position of the cursor (page, line, column), paper size, maximum number of characters, maximum number of lines, full-width/half-width, etc. This area displays various guidance in text. For example, in the display example shown in Figure 7, from the left, the hiragana input mode is ``flat'', the full-width input is ``full'', the paper size is rA4J, the maximum number of characters is ``48'', and the maximum number of lines is ``40''.
Current position of cursor: “1”, page “15”, line “20”
It shows the digit.

Further, the guidance display screen 502 displays work guidance, error messages, etc. as necessary. Furthermore, the guidance display screen 502 also displays candidates selected when converting single kanji, symbol input, external character input, etc., English characters input in Roman alphabet input mode, enlargement size specification when setting enlarged characters, etc. .

At the bottom of the guidance display screen 502 is an area 508 for displaying printing conditions. Below the area 508, printing conditions as shown in the figure are written in characters and symbols 511, and correspondingly, rectangular instruction marks 510 are selectively indicated in the liquid crystal display screen area 50B.

Printing conditions include character spacing, line spacing, print type (mode),
and 6-character spacing and line spacing, which display the current settings for vertical and horizontal writing, respectively.
Wide, medium, and narrow can be displayed, and regarding the print mode,
Normal printing, sequential printing, and mid-stop printing can be displayed.

The display example in FIG. 7 shows horizontal writing in normal printing with medium line spacing and character spacing.

The format layout of the document is always displayed on the layout display screen 504 in this device. One character is displayed as one dot, and the cursor position is indicated by blinking the dot. Also, like characters, the lines are displayed as dots, but in terms of layout display, this device has two modes: a mode in which characters and lines are displayed together, and a mode in which only the lines are displayed.

Such various displays are controlled by the display control section 26, and FIG. 4 shows a detailed functional configuration of the display control section 2B. For example, various control units such as the character display control unit 302 perform control operations corresponding to the code data stored in the code data storage area 21B.

The character display control unit 302 controls the code data storage area 21
The character patterns stored in the character pattern storage area 304 are read out according to the text code data stored in 8 and transferred to the text display data storage area 30El as display data, such as a dot pattern, to be displayed on the display section 24.

Double-width characters can be set for wooden layouts. This is keyboard 1
When a double-width character is set by 0, the character at the current position of the cursor is displayed in double-width on the display section 24, and the cursor is moved to the next position. This double-angle operation is identified by the function key conversion unit 214 and is performed by the double-angle display control unit 30B according to the code data stored in the code data storage area 216.
08 reads double-width pattern data from the character pattern storage area 304 and stores it in the text display data storage area 306.

Angline, cursor, visible line, left and right edges of the paper (margin, scale), etc. are displayed by the angry line control section 31O, the cursor display control section 312, and the visible line display control section 314, respectively. and is performed by the left and right end display control section 316. These display data are stored in an angle display data storage area 318, a cursor display data storage area 320, and so on, respectively. Key line display data storage area 322
．． and stored in the scale display data storage area 324.

These display data storage areas 306.318.320
The display data accumulated in ゜322 and 324 are combined by the 1-display data generation section 32B, and the accumulated 0-display data generation section 32B generates a maximum of 1 line of text, line, cursor, and scale data. That is, this embodiment has a maximum storage capacity of 104 digits.

Code data storage area 2 input from keyboard 10
The scroll instruction for the display screen stored in 16 is taken into the scroll control section 328, and the latter gives the scroll instruction to the display data creation section 32B to add scroll information to the display data. In this way, the display data corresponding to the display screen on the display section 24 is transferred to the display data creation section 3.
26 and accumulated in the display data storage area 330, the 0 display data storage area 330 has a storage area corresponding to the display screen of the display unit 24, and is stored in the VRAM 114.
A VRAM copy corresponding to (FIG. 2) is formed. This VRAM copy holds the data to be displayed on the 1 display section 24. Correction of the 0 display data is performed using this VR
This is done by modifying the contents of the AM copy, and the modified data is transferred to the VRAM 114 all at once.

The character information displayed on the guidance display screen 502 is created by the guidance display control unit 300 according to the character display data from the character display control unit 302 and the input mode from the input mode control unit 208, and is also accumulated in the display data storage area 330. be done. At this time, black and white reversal of one displayed character is instructed by the black and white reversal control section 33B to the guidance display control section 300. Mark 51 for instructing printing conditions
0 is visualized by the guidance control unit 300 making a rectangular black dot at the position of the corresponding printing condition notation 511 based on the input data regarding the printing conditions from the input mode control unit 208 .

The layout display control unit 332 includes a text display data storage area 30B and a cursor display data storage area 320.
．． Layout display data is formed based on the accumulated data in the line display data storage area 322 and is stored in the display data storage area 330. The display data accumulated in the display data storage area 330 in this way is
The data is read out to the upper 34 display section 24 of the MRAM changing section and displayed on the display section 24.

By the way, there are three printing modes by the printing unit 22: normal printing, sequential printing, and mid-stop printing. Normal printing is a mode in which all characters and highlighted lines included from the beginning to the end of the current page are printed. be. In sequential printing, a sentence is printed when the device is in input mode and a line break or page break is performed. That is, the character following the nearest line break or page break before the cursor's current position,
Or, if there is no line break, the characters from the beginning of the page to the current cursor position, or the characters from the current cursor position to the nearest line feed, page break, or end of the page are printed.

This device can input a "print stop character" using a specific key. In mid-stop printing, the characters from the current cursor position to the character immediately before the print stop character or the end of the page are printed. After printing up to this point, characters can be input manually from the keyboard 10 by '&'.

Referring to FIG. 5, a detailed configuration of the print control section 20 that performs such print control is shown, and the print control section 20 has a print mode control section 400. This is to read input data from the code data storage area 216 and start the print control section 20. Print mode control unit 400
has a print mode storage area, and a print range control unit 40
The paper feed control unit 40 instructs the head transfer control unit 402 to move the print head.
4 is instructed to feed paper.

Print range control unit 406. has a function of receiving information on the current position of the print head from the head transfer control unit 402 and information on the current position of the cursor from the cursor display control unit 312, and calculating the print target range. As a result, the above-mentioned "line feed" code for sequential printing is detected.

The print range information formed by the print range control unit 40B is transmitted to the text development unit 408 and the line data development unit 4.
Sent to 10. The text development unit 408 reads text data from the text data storage area 412 in the code data storage area 21θ, calculates a printing area, and develops it in a text development area therein. At this time, if the print mode is vertical writing, the vertical writing control unit 414 determines whether or not the character is prohibited from being rotated by 90°, and rotation instruction information is added thereto.

The print head of the printing section 22 is transferred by the head transfer control section 4.
02, and information indicating the current head position is input to between print ranges @408. Further, the paper feeding mechanism that feeds the recording medium of the printing section 22 is controlled by the paper feeding control section 4.
04 to control the advance and return of the recording paper.

These head transfer control section 402 and paper feed control section 404
is under the control of the format creation section 41B. Format creation section 4]
8 takes in input information about line spacing, character spacing, and left and right edges from the line spacing/character spacing storage area and the left and right edge information storage areas of the code data storage area 21B, and the 0 line information forming the print format is text. Deployment section 40
8 and is used to calculate the printing area. The paper feed control unit 404 receives line spacing information from the format creation unit 4113, and controls the paper feeding direction and amount of paper fed to the printing unit 22. Further, the head transfer control unit 402 receives character spacing information from the format creation unit 41B, and controls the feeding direction and feeding amount of the print head.

The line data development unit 410 has a line data storage area, receives print range information from the print range control unit 406, and develops the line pattern data in the line pattern development area 418.

The text data developed in the text development section 408 is 1
The character pattern capture control unit 420 reads out the information, and develops it in the character pattern development area 422 in the form of the corresponding pattern information read out from the character pattern storage area 304.

The characters and the line pattern developed in the character pattern development area 422 and the line pattern development area 418 are converted into print data according to the print format by the print data creation section 424 in the print data storage area 418.
It is stored in 2B. At that time, the interval correction control unit 428
Line spacing printing that makes the gaps between the lines and angle lines continuous for the print data stored in the print data storage area 42B.

Similarly, the enlargement processing unit 430, which performs spacing correction such as character amount printing, enlarges the pattern to be printed and performs enlargement processing such as making the line spacing continuous or expanding the space. The data is developed in the enlarged data development area therein and finally stored in the print data storage area 426.

The print data stored in the print data storage area 42B is supplied to the print head of the printing section 22, and is thereby printed out.

By the way, FIG. 8 conceptually shows the display control performed by the display control unit 26, focusing on text display, gray line display, and layout display. As you will see, first, one line of text expansion data 52
0 is expanded, and a dot pattern 524 is expanded by character pattern generation 522. This is stored as text display data in the display data creation section 32B. At this time, display data 526 for the scale, left and right ends, angle lines, and cursor are developed in the respective corresponding areas. Also, one line of line data 528 is developed as line display data. For these display data, data for 17 full-width characters after the position indicated by the scroll pointer 548 are cut out, a logical sum 530 is taken, and the resultant data is stored in the display data storage area 330.

As described above, this device can display one page's worth of layout on the layout display screen 504. This is mainly executed by the layout display control section 332, and examples of its operation flow are shown in FIGS. 9 to 12. Here, the column counter is a counter that counts character positions or digits in half-width units.

Therefore, in these flowcharts, adding 2 to the column counter causes the column counter to advance by a full-width position, and adding 1 causes the column counter to advance by a half-width position.

First, a digit correspondence address table 532 is created from one line of expanded text data 520, and layout display data 534 is created based on this. In that case, two digits of data are logically summed and converted into one-dot data (black) for display. Of course, areas outside the left and right margins, spaces, line breaks, and page breaks are converted to white dot data. Similarly, layer/wood display data 536 is formed from one line of line data 528.

As mentioned above, this device has two types of layout display modes: normal layout display that displays a layout that includes both single characters and gray lines, and gray line layout that displays a layout that includes only gray lines. It is a display. A virtual switch 540 is switched by such a layout display mode 538. This switching is performed in response to a function key on the keyboard 10 that selects the layout display mode. Further, the size of the frame on the layout display screen is changed according to the selected paper size A4 or B5. Furthermore, when normal printing is selected, changing the character spacing or line spacing also changes the layout display.

When the virtual switch 540 is in the illustrated state, that is, in normal layout display, text layout display data 534 and line layout display data 536 are displayed.
The logical sum 542 of the dot patterns is calculated to create a dot pattern 544. The virtual switch 542 is in a state opposite to that shown in the diagram,
That is, in the case of the gray line layout display, only the gray line layout display data 53B is converted into a dot pattern. These dot pattern data are stored in an area corresponding to the layout display screen 504 of the 1-display data storage area 330. These operations are performed for each row, and one page's worth of layout display dot data is developed in the layout area. Note that the dot at the current position of the cursor is displayed as a plink on the layout display screen 504.

In this embodiment, by being able to select between two types of layout display modes, the overall layout can be easily grasped, and if necessary, the overall configuration of the cables can be easily confirmed, making it possible to display an easy-to-read layout. is provided.

As shown in FIG. 13, the C line displayed on the editing screen 500 is displayed from the center in four directions (up, down, left, and right) in the double-byte character display area 580, and this is the basic component that is the minimum constituent unit of the C line. In other words, it constitutes a wire segment. These four key line segments are designated by reference numeral 582 in the figure. The pixel pattern of the line segment 562 is stored in the character pattern storage area 304. In this embodiment, the line display data is generated by the line display control unit 314 in response to simultaneous operation of the control key 584 and the cursor movement key 566 (FIG. 15) of the keyboard IO.

As shown in FIG. 13, one line display data is composed of a 4-bit code indicating the up, down, left, and right directions. Therefore, the line display data is stored in the line display data storage area 322 in the form of the logical sum of these 4-bit codes. For example, as shown in Figure 14, the key line 568 in the upper right corner of the table is the 4-bit code roo1
It is expressed as the logical sum ro110J of 0J and rolooJ. In this way, all patterns of key lines can be expressed in 4-bit codes. One byte, the minimum unit of data handled within the system, can handle two full-width characters. Therefore, it is advantageous for these line display data to be handled in the system internal memory in units of arithmetic processing, that is, 4 bits, and to be extracted in external storage files in units of 8 bits, that is, 1 byte. .

As shown in FIG. 15, the line display control unit 314 imports the current cursor position (570) and stores the line data at that position in the line display data storage area 32.
2 and calculates the exclusive OR of this and the new line data to be set (572), that is, the line data at the current cursor position and the value indicated by the cursor key 568 operated while holding down the control key 564. Find the part that does not match the direction. Set the calculation result as the key line data at the currently specified cursor position574),
The key line data for the new cursor position is written to the corresponding storage location in the key line display data storage area 322. Therefore, the same key line data is always output for the same cursor key data. Based on the created line data, the pixel pattern of the line segment 562 is read out from the character pattern storage area 304, and the pixel pattern of the line segment 562 is read out from the character pattern storage area 304. It is output to the printing unit 22 or the like.

For example, suppose that the cursor is located at the highlighted line portion 57B in FIG. 14 and the upward cursor key is operated. 18th A
From the figure, control passes through jump symbol 11 to FIG. 16B. The key line data captured in step 578 is
It's rlloOJ. Therefore, in step 580,
Key line data currently input using the cursor keys r 10
The exclusive OR ro100J with 0OJ is taken, and this becomes the key line data at the new cursor position (582)
, that is, an upward Ke line is formed.

Since such exclusive OR is performed, when the cursor is moved to a certain position on the line, the part of the line that matches the direction of movement of the cursor is erased. for example,
When the key line data at the character position directly below the current cursor position is rolooJ, if you operate the down cursor key together with the control key, the key manual data r0100J and the key line data ro10 at the current cursor position
The logical sum r 0OOOJ with 0J is taken, and the Kay line is erased. In this way, the control key 564 and the cursor key 5
By operating 66 at the same time, it is possible to set and erase the key line.

Various examples of forming a line by moving the cursor to the right are shown in FIGS. 17A to 17E. In the same figure, reference numeral 590 indicates a cursor display.

In this embodiment, by adopting such a configuration of the line data, efficient processing of the line data is possible.As mentioned above, in this embodiment, there are three types of printing: normal printing, sequential printing, and mid-stop printing. There is. These can be selectively specified using specific keys on the keyboard IO. Regarding formats for printing and editing, paper size, line spacing, character spacing, vertical/horizontal writing, etc. can also be specified using specific keys. Regarding the paper size, A4 and B5 can be selected. Regarding the one character spacing, the gap between the dot forming areas of two adjacent characters is, for example, 0.
．． There are three types to choose from: 28 mm, 0.56 mm, and 141 mm.
If the gap between two rows of dot forming areas is, for example, 0.8
5ts, 2.98mm, and 5.08+smc7)
There are three types to choose from.

Such format conditions are controlled by the format creation unit 418 of the print control unit 20 for printing formats, and by &li
The i-collection format can be changed in the input mode under the control of the editing section 16 and the left and right end display control section 31B of the display control section 26. When changing the print mode, data regarding the selected line spacing, one character spacing, and vertical/horizontal writing is set for printing regardless of the print type.

When the normal print mode is selected, all items including paper size can be selected. Furthermore, the selected item is reflected in both printing and editing formats, and the text and layout are re-edited accordingly. When sequential printing and mid-stop printing modes are selected, items other than paper size can be selected. Therefore, it is possible to edit input data using the line spacing and character spacing selected during normal printing, and select sequential printing or mid-stop printing to print with a different line spacing, spacing, and/or character spacing. . Note that the selected item is reflected in the print format and does not affect editing.

In addition, the set printing conditions, especially the printing condition items that can be temporarily changed as described above, are controlled by the guidance display control unit 300, such as line spacing, character spacing, print type, and height. - Area 5 of the display section 24 for horizontal writing, paper size, maximum number of characters, and maximum number of lines.
08 and 502. By constantly displaying printing conditions in this way, the burden on the operator is reduced.
There are fewer chances of printing errors and reprinting.

FIG. 18 conceptually shows an outline of the format change operation performed by the editing section 16 and the format creation section 416.

As you will see, the keyboard 10 allows you to set the print type, paper size, line spacing, one character spacing, and vertical/horizontal writing. These configuration data are
For now, 0 is stored in the code data storage area 21B.
When normal printing is selected, the editing section 16 and the formatting section 41B take in these setting data and set the formatting data for both printing and editing as print type, paper size,
You can change line spacing, character spacing, and vertical/horizontal writing. The editing unit 16 re-edits the text and layout according to the changed data.
The format creation unit 418 changes the text data in the text development unit 408 for printing, and also changes the control data in the head transfer control unit 402 and paper feed control unit 404. Therefore, head transfer control f! 840B feeds the print head of the printing unit 22 by a pitch corresponding to the predetermined amount described above,
Further, the paper feed control unit 404 feeds the recording paper of the printing unit 22 by a pitch corresponding to the predetermined amount described above.

When continuous printing or intermittent printing is selected.

The printing format is changed according to the line spacing, one-character spacing, and vertical/horizontal writing information.

By the way, this device has cursor skip and head skip functions. Cursor skip moves the cursor to the digit position on the editing screen 500 that corresponds to the current position of the print head on the printing unit 22 by operating a specific key on the keyboard 10, and displays the cursor at the current digit position of the print head. This is a function to adjust the position. In addition, head skipping is a function in which printing on the printing section 22 is skipped to a position corresponding to the digit position of the cursor displayed on the editing screen 500 on the display section 24 by operating a specific key on the keyboard 10.
This function moves the print head F and aligns the print head with the cursor display position. At that time, the 8th digit of the print head is
Calculated based on the character spacing set for printing.

The left-right movement of 17 to print is performed by one full-width character when in the full-width input mode, and by one half-width character when in the half-width input mode, based on the character spacing set for printing. The feeding of the recording paper, that is, line feed and line return, is also calculated using the line spacing set for printing as a unit, and feeding is possible in the forward and reverse directions. The movement of these print heads and line advance/line return are performed in accordance with the operation of a specific key on the keyboard 10, respectively.

It is controlled by a head transfer control section 402 and a paper feed control section 404.

More specifically, the cursor skip is performed using the character spacing data 800 stored in the code data storage area 216 and set for printing, as conceptually shown in FIG. and data 6 of the current print head dot position from the head transfer control unit 402.
Calculate the current print head digit position from 02 (6'04
), as can be seen from FIG. 17, in this embodiment, the cursor 590 has a length corresponding to the half-width character width, so the cursor digit position is also calculated in units of half-width character width. Based on the calculated current head digit position, the cursor display control unit 312 updates the cursor position data in the cursor display data storage area 320 (5oe) and supplies the updated cursor position data to the cursor display area 50B. A specific operational flow of such cursor skip processing is shown in FIG.

The head skip is an operation performed by the head transfer control section 402, as conceptually shown in FIG.

The dot position to which the print head is to be moved is calculated from the character spacing data 800 set for printing stored in the code data storage area 216 and the current cursor position data 610 of the cursor display control unit 312 (812). ,
The calculation of the second dot position is also performed based on the number of dots in the half-width character width. Based on the calculated head dot position and the current head dot position data 802, the head transfer cap 102 calculates the amount by which the print head should be transferred (f314), and controls the head transfer unit 81B accordingly. to move the print head of the printing unit 22 by the calculated amount.

If the calculated value is positive, it is moved to the right, and if it is negative, it is moved to the left. At the same time, the rad dot position data 602 in the head position data storage area is updated.

FIG. 22 shows a specific operational flow of such head skip processing.

As described above, in this embodiment, it is possible to grasp the correspondence between the print start position on the printer and the cursor display position on the document editing screen with a simple operation. Therefore, operational efficiency during printing and editing is improved, and the burden on the operator is reduced.

Referring to FIG. 23, the head transfer control performed by the head transfer control unit 402 is conceptually shown. Directional movement is instructed, and by simultaneous operation of control key 584 and non-conversion key 822, leftward movement of the print head is instructed. In response to this, the head movement control unit 402 calculates the head movement amount from the printing character spacing data 600 and the full-size half-width mode information 824 (82B).

The head movement amount is the sum of the number of full-width character dots and the printing character spacing, but if the full-width/half-width mode information is set to "0" for full-width and "1" for half-width, a single logical formula, ( Full-width character dots (character spacing for printing) / (all Φ half-width mode information + 1
) is calculated.

The number of dots to be moved and the direction of movement thus calculated are provided to the head transfer section 616, thereby causing the print head of the printing section 22 to move. Therefore, when full-width mode is specified, the print head moves by the full-width character width,
When half-width mode is specified, the print head moves in half-width character width units. It is also stored in the head position data storage area as new head dot position data 11102. A specific operational flow of such head transfer processing is shown in FIGS. 24A and 24B.

Referring to FIG. 25, paper feed control performed by the paper feed control unit 404 is conceptually shown. In this embodiment, line feed is instructed by operating the paper feed key 632 of the keyboard 10, and the control key 564 and paper feed key 832 simultaneously, line return is instructed. In response to this, the paper feed control unit 404 controls the paper feed (
Return) Calculate the amount (+334), ! The paper feed (return) amount and paper feed (return) direction are determined by the paper feed (return) section 6.
3B, and the printing unit 22 is fed accordingly. Therefore, the recording paper is fed (returned) in the designated direction by an amount corresponding to the set printing line spacing. FIG. 28 shows a specific operational flow of such paper feeding processing.

By the way, this device can use a mid-stop print mode. In this mode, while printing text data into which a print stop character has been input, when the print position reaches the print stop character included in the text data, the printing operation is interrupted and the sequential print mode is entered.

More specifically, when a specific key on the keyboard IO is operated, mid-stop printing is started, printing starts from the character at the current cursor position to the character immediately before the print stop character, and then the printing operation is stopped and the characters are pressed by pressing the key. It will be possible to do it manually. If there is no print stop character, the end of the page will be printed,
A similar situation will occur. The print stop character is input using a specific key, and a specific mark such as "S" surrounded by a hexagon is displayed on the display unit 24. Print stop characters are not printed.

By creating a document that includes print stop characters, and repeating printing start, stop printing, inputting characters, and start printing midway,
It is possible to efficiently output a plurality of text documents in which some parts are different but most other parts are the same.

The mid-stop printing is mainly controlled by the print mode control section 400, the format creation section 418, and the text development section 408, and FIG. 27 conceptually shows the pattern thereof.

The line format, that is, the left and right edge information for printing of that line is created using the current head position data 650 and the left and right edge data 844 ([14B). According to this line format, the print stop character is created from the current cursor position, that is, the expansion start character address. The text data 840 containing the text is expanded into text (842).

The expanded text data is processed by the print processing unit 85B that stops midway.
given to. Here, if the print type 648 specifies mid-stop printing, the print stop character is replaced with a full-width space, and the expanded data is sequentially supplied to the print data output unit 660.

The text expansion 642 also creates a digit correspondence address table from the expansion start character, and the address of the print stop character included in the text line is given to the line data correction unit 658. On the other hand, the line data development section 854 is given the line data 652 and the left and right edge information for printing, and forms line data from the development start character to the digit position including the print stop character. The line data correction unit 658 converts the line data up to just before the print stop character into the print data output unit 6.
Supply to 80. In this way, the print data output unit 660
The characters of the text developed in the mid-stop print processing unit 856 are sequentially output to the printing unit 22, and when a print stop character is reached, a print stop command is output. At this point, the system is in a state where characters can be entered manually from the keyboard. A specific operational flow of such mid-stop print processing is shown in FIGS. 28A and 28B.

In this embodiment, midway stop printing can be performed by including a specific control character, that is, a print stop character, in the document text.

As a result, type-in printing or insertion printing in which characters are printed at a predetermined position on a predetermined form can be realized without requiring external storage, complicated functions, or operations.

By the way, with this device, a character font can be enlarged and printed as one of the emphasized characters such as an underline or double-width character. The enlargement size can be set on a line-by-line basis for the line at the current cursor position, and in this embodiment, it can be enlarged in the editing screen 500 and layout screen 504 of the 0 display section 24, which can be enlarged vertically and horizontally by an integral number of times up to 24 times. Although not displayed, it is enlarged and printed on the printing section 22. Note that if the enlarged image exceeds the size of the recording paper, it will be reduced to fit it.

Such character font enlargement control is performed by the print control unit 20.
The print data creation unit 424 is
This is executed for the print data. In order to explain this in an easy-to-understand manner, as shown in Figure 28, up to 4
7jTJ20th line to 2nd in the 0th line print area 670
Processing will be described when an instruction is given to enlarge the text on the 10th line by 15 times vertically while the print text on the 20th line is enlarged 10 times vertically and horizontally using 9 lines.

In this example, the enlargement processing section 430 performs processing as conceptually shown in FIG. 30. First, the enlargement processing section 43
0 indicates that the maximum number of lines "40" set as format information is imported, and the enlargement information of each line is imported as enlargement information data. In this case, the 20th line is specified to be enlarged by 10 times in the vertical and horizontal directions. Data is captured. The operator uses the keyboard lO to move the cursor to
Position it on the 0th line, and expand it vertically by 15 times,
When you give an instruction to request 10x horizontal enlargement, these data, current cursor line number riot, and requested vertical enlargement magnification "
15'' and the requested lateral enlargement magnification ``lO'' are imported.

Therefore, the enlargement processing unit 430 calculates the maximum magnification of vertical enlargement that can be set from the format information, enlargement information data, and current cursor line number (872). Find the number of rows that do not. In this example, since the 20th line is set to be enlarged 10 times vertically and horizontally, the 20th to 29th lines are consumed as enlargement.

Therefore, the remaining non-expanding rows are 11 from the 30th to the 40th row.
It is a line. If the first O row, which is the target of enlargement, is added to this, the maximum number of rows allowed to be used for enlargement, that is, the maximum magnification, is "12".

Next, this maximum magnification “12” and the required vertical enlargement magnification “15”
The vertical expansion magnification is corrected to "12" within the maximum magnification limit (E174), and the requested horizontal expansion magnification "10" is used (878), which is the same as the expansion information table. FIG. 31 shows an example of the registered contents of the table 680, which are registered in the table 680 along with the page number and line number (67B). Based on this table 680, the print data creation unit 424 modifies the pattern data in the character pattern development area 422 and the C line pattern development area 418 to create print data.

The enlarged pattern data is output to the printing unit 22, and enlarged printing is performed. A specific operational flow of such enlarged printing processing is shown in FIGS. 32A to 32E.

To add some additional explanation to this operation flow, the guidance display screen 502 displays vertical and horizontal magnifications. This magnification, for example, a predetermined number is displayed as a default value, and the vertical or horizontal magnification, whichever is displayed in reverse, can be corrected using the up cursor movement key or the down cursor movement key. Operating the up cursor movement key increases the magnification, and operating the down cursor movement key decreases the magnification. Enlargement processing is executed by operating the line feed key.

In this manner, in this embodiment, the enlarged size of the character font can be set for each line, and printing can be performed using the enlarged font. Therefore, enlarged characters can be printed with a relatively simple operation.

In this embodiment, as described above, the hiragana input mode and the alphanumeric/symbol input mode can be used for normal character input other than control characters. In hiragana input mode, segment-by-segment kana-kanji conversion, katakana conversion, and single kanji conversion are available.
Kana-Kanji conversion uses the latest usage learning method. Non-kanji characters such as special symbols are input in alphanumeric/symbol input mode. These details are not directly related to the understanding of the present invention, so their explanation will be omitted.

General characters that can be used in these input modes are registered in the conversion dictionary 104 of the editing section 16.

However, for unregistered characters, symbols, figures, etc., fonts can be created by this device and input as external characters. Font creation is performed using the layout screen 504. Call the already registered font to the editing screen 500 and display it on the layout screen 50
4), it is also possible to modify and use the same font, or the same font can be used as a custom character without modification. You can also create a new one from a blank slate.

The created external characters are displayed together with candidate numbers on the guidance screen 502 as in the case of single kanji conversion, and by selecting number 1, the created external characters are displayed in the document text, that is, on the editing screen 5.
00 can be entered. In the example shown in Figure 35, the number "1"
Two external characters have already been registered for "2" and "2". The created external characters can be registered on the document floppy in 2 days. Also, the external characters registered in the document floppy 28 are read into the storage section 18 and used.

The creation process of external characters is mainly performed by the input control section 12 and the display control section 28. Already edit screen 500
FIG. 33 conceptually shows the process of modifying the characters of the text displayed on the screen and registering them as external characters.

As will be seen from now on, when a specific key on the keyboard 10 is operated, the already registered external characters are displayed on the 6 display section 22, which is used for the external character pattern creation work, as shown in FIG. 35, for example. Therefore, if you want to create a new one, select "3" to "8" using the numeric keys. If modifying a registered pattern, select "1" or "2".

Select a custom character copy by operating a specific key (special character key). FIG. 34 shows an example of the operation flow for copying external characters. next,
For example, in the example shown in Figure 35, if you operate the number key "3",
In response to this operation, first, the information 61 of the current cursor digit position is
0 is fetched and the address of the character at the current cursor position is obtained by referring to the 1-digit correspondence address table 532 (89
0), Search the text data 640 based on the obtained address information and obtain the code of the character corresponding to the address (892). Based on this code data, read the font pattern from the character pattern generation section 522 and store the external character pattern. This is stored together with the registration number in the third area of area 69B (H4). When the number key "2" is pressed, the external characters of the registration number "2" are changed. In this embodiment, the registered capacity is 63 characters.

The layout display control section 332 of the display control section 26 reads out the pattern information in the external character pattern storage area 686 into the display data storage area 330 and displays it on the layout display screen 504 of the display section 24 .

Modification of the font called up on the layout screen 504 or creation of a non-standard character pattern from blank paper is performed as follows. In this embodiment, the layout screen 504 displays 48 dots in the vertical and horizontal directions, and one pixel in the character font is represented by a rectangle of 2 dots in the vertical and horizontal directions. As shown in FIG. 36, the cursor 898 is at 1 on the layout screen 504.
It is displayed by blinking the lower two dots (hatched portion in the figure) of the four pixel dots. This cursor 698 can also be moved using the cursor key 586 on the keyboard IO. By operating a specific key on the keyboard 10, one pixel at the position of the cursor 698 can be made black or white. When this specific key is pressed, the pixel indicated by the cursor 698 changes to black if it is a white pixel, and changes to white if it is a black pixel. FIG. 37 shows a state in which a custom character pattern has been created. When a specific key is operated in this state, the custom character is registered at the position of the corresponding number, "3" in the example of FIG. 35.

As described above, this embodiment has a function of copying characters displayed on the screen to the external character area. Therefore, desired external characters can be created with a simple operation.

The device according to this embodiment may optionally include, for example, three
．． An external storage device such as a 5-inch standard Flow I disk can be connected. Documents can be registered in the floppy disk 28 and the registered documents can be called up. The floppy 28 can be used as a document floppy by initializing it.

Initialization is performed as follows. First, the keyboard 10
A menu is displayed on the display section 24 as shown in FIG. 38 by operating a specific key. Then press the number key "4"
When you press , a confirmation message is displayed, and when you press a specific key, initialization is executed. by this,
All documents registered on the floppy disk 28 are cleared.

In the menu display shown in Figure 38, press the numeric key "2"
When is pressed, a display like the one shown in FIG. 38 is displayed, and the document can be registered in the floppy disk 28.

In this embodiment, data is recorded on the floppy disk 28 in a format as shown in FIG. That is, a header section 700, a ledger section 702, a document area 704, and an external character section 706. The header section 700 records an ID, the maximum number of documents that can be registered, and the number of registered documents. In the ledger section 702, a document name written in a maximum of 10 characters, and format data such as paper size, line spacing of 1 character, and vertical/horizontal writing format are stored.
Information such as right edge, enlargement, and lines, and up to 20 texts
Recorded in 0 documents. The external character section can accommodate up to 64 external characters.

Returning to FIG. 39, as shown in the guidance area 502, if you operate either the cursor up or down key in this state, the display of document numbers, that is, the identification display, shifts forward or backward one by one accordingly. In the embodiment, only document numbers without document names are picked up in the new registration mode, and only document numbers with document names are picked up in the registered update registration mode, and rotated and displayed in response to the cursor up and down keys. In the registered update registration mode, when the document shifts to the 200th document in the registered capacity, if the down shift key is further operated, the display returns to the first document and then returns to displaying the document name of the first registered document number. Similarly, when you have shifted to the first document, if you press the up shift key again, you will go back to the 200th document and then the document name of the last registered document number will be rotated and displayed.

A document number whose document name is blank indicates that nothing is registered in that area.0 When registering a created document, display such an area without a document name and register in it. 0 To overwrite an existing document with a created document, simply find the existing document name and register it using that document number.

Display the desired document number and press a specific key, such as the line feed key, to enter the document name using the character keys.0After entering the document name, or using the already called document name After using or modifying the document, press the return key again to register the document. Registration cannot be performed without even a single character being input as the document name. If the document currently being created is called from the floppy 28, the document name will be displayed first at the time of registration.

Such document registration control is mainly performed by the external storage control section 3.
This is done by 0. The situation is conceptually shown in Figure 41. First, let's look at the editorial department! Document information 71 being edited in 6
The document number and document name are obtained from 0, and the mode of document operation is determined from this (712). If the first bit of the document name data is rOJ, it is a new registration mode, and if the document name code exists, it is an already registered document. Enters update mode. A document ledger is read into the storage unit 18 from the ledger unit 702 of the 2nd floppy disk, and the document name search unit 7 reads from this ledger 702.
14 corresponds to the cursor up and down keys 720 and 722 pressed from the keyboard 10 (717°718)
Search for document number. At this time, in the new registration mode, only document numbers with the leading data of the document name "0" are picked up, and in the registered update registration mode, only document numbers with document names are picked up.

The document number and document name picked up in this way are
The text is converted into a corresponding character font pattern and displayed on the display section 2. A specific operational flow of the document name search process in such document registration is shown in FIGS. 42A to 428.

When calling up a document registered in the floppy disk 28, the menu shown in FIG. 39 is displayed by operating the numeric key rlJ on the menu display shown in FIG. As in the case of registration, by operating the cursor up and down keys 720 or 722 to rotate and display the desired document name, and operating the line return key with the desired document name displayed, the registered document can be recalled. .

According to this embodiment, the document registration area in the external storage device is distinguished between registered documents and unregistered documents, and only the unregistered area is displayed in the new registration mode, and the registered area is displayed in the registered document update mode. Display only. This display is
The cursor is rotated by operating the cursor up and down keys 720 and 722. By limiting the selection range of the registration operation in this way, there are two types of operation error effects such as accidentally deleting a registered document or rewriting it with another document. By being able to select the layout display mode, you can easily understand the overall layout, and if necessary, you can clearly check the overall composition of ruled lines, making it easier to see.
