Store it in this. In this way, the code data storage area 216 stores the input code data of the keys input from the keyboard IO.

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 artist 504. The overall size of these screens is, for example, 472 dots horizontally and 64 dots vertically.
It's a dot. The editing screen 500 can display 17 full-width characters of text and double-byte lines, and a character string converted from an input character string to kana-kanji is displayed here, and the user operates the keyboard 10 while looking at this to perform editing operations. be able to. In the display example shown in FIG. 7, the character strings "Aiueo" and "Kukeko" are displayed in full-width characters, "r ABCDJ" is displayed in half-width characters, and "r'f)-ki" is displayed in double-width characters in area 500. .

The lower part of the editing screen 500 includes an area 508 where an angle, cursor, scale, etc. are displayed.

The cursor displayed in area 50B 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 omits the 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/half-width, etc. This area displays various guidance in text. For example, in the display example in Figure 7, from the left, hiragana input mode "flat", full-width input "full", paper size rA4J, maximum number of characters "48 characters", maximum number of lines r4
0 line”, cursor current position rlJ page “15” line “20
” indicates 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 during single character conversion, symbol input, custom character input, etc., alphabetic characters input in Roman alphabet input mode, enlargement size specification when setting enlarged characters, etc. Ru.

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 rectangular instruction marks 510 are selectively indicated in the liquid crystal display screen area 508 in correspondence with them.

Printing conditions include character spacing, line spacing, print type (mode),
For 0 character spacing and line spacing, the current settings for vertical and horizontal writing are displayed, 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.

These various displays are controlled by the display control section 26, and FIG. 4 shows the detailed functional configuration of the display control section 26. For example, various control units such as the character display control unit 302 perform control operations corresponding to code data stored in the code data storage area 216.

The character display control unit 302 controls the code data storage area 21
According to the text code data stored in B, the character pattern stored in the character pattern storage area 304 is read out and transferred to the text display data storage area 308 as display data such as a dot pattern to be displayed on the display unit 24.

This device can set double-width characters. This is the keyboard l
When a double-width character is set by O, 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 21B.
08 reads double-width pattern data from the character pattern storage area 304 and stores it in the text display data storage area 30B.

Display of the angline, cursor, key line, left and right edges of the paper (margin, scale), etc. are performed by the angline control section 310. Cursor display control section 312, line display control section 314. This is performed by the left and right end display control section 31B. 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 308.318.320
The display data accumulated in 322 and 324 are synthesized by a display data generation unit 326, and the accumulated 0 display data generation unit 32B generates data for up to one line of text, line, cursor, and scale. 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 1B is taken into the scroll control section 328, and the latter gives the scroll instruction to the 1 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 unit 24 is transferred to the display data creation unit 32.
Formed at 6.

The zero display data storage area 330 stored in the display data storage area 330 has a storage area corresponding to the display screen of the display unit 24, and forms a VRAM copy corresponding to the VRAM 114 (FIG. 2). This VRAM copy holds the data to be displayed on the display unit 24. Correction of the 0 display data is performed by correcting the contents of this VRAM, and the corrected data is
The data is transferred to the RAM 114 all at once.

The character information displayed on the guidance display screen 502 is character display data from the character display control unit 302.

and the guidance display control unit 300 according to the input mode from the input mode control unit 208, and are also stored in the display data storage area 330. At this time, black and white reversal of the displayed characters is instructed by the black and white reversal control section 33B to the guidance display control section 300. The mark 510 instructing the printing conditions 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. be done.

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 AMRAM change section upper 34 is read out to the display section 24 and displayed on the display section 24.

By the way, there are three printing modes by the printing unit 22: 1 normal printing, sequential printing, and midway stop printing. 0 normal printing is a mode that prints all characters and highlighted lines included from the beginning to the end of the current page. 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, the state returns to the state where characters can be entered manually from the keyboard 10.

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
6 to start up, and also instructs the head transfer control unit 402 to move the print head, and the paper feed control unit 40
4 is instructed to feed paper.

The print range control unit 40B has a function of receiving information on the current position of the print head from the head transfer control unit 402, and receiving information on the current position of the cursor from the cursor display control unit 312, and calculating a 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 406 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 21B, calculates a printing area, and develops it in a text development area within the text data storage area 412. 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 80°, 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 the print range control section 40B. 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 41
B takes in input information about line spacing, character spacing, and left and right edges from the line spacing/character spacing storage area and left and right edge information storage areas of the code data storage area 218, 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 418,
Controls the paper feed direction and paper feed amount of the printing unit 22. Further, the head transfer control unit 402 receives character spacing information from the format creation unit 416, 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
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.
26. At that time, the interval correction control unit 428
Similarly, the enlargement processing unit 430 performs interval correction such as line spacing printing and character amount printing to make the mutual gaps between the lines and angle lines continuous with respect to the print data stored in the print data storage area 426. Enlarge the pattern
The enlarged pattern data, which undergoes enlargement processing such as making the line spacing continuous or expanding the space, is developed in the enlarged data development area therein, and is 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 section 28, 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 in the 1-display data creation section 326 as text display data. 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. From these display data, data for 17 full-width characters after the position indicated by the scroll pointer 546 is 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 1,1 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, layout display data 536 is formed from one line of line data 528.

As mentioned above, this device has two types of layout display modes: the normal layout display that displays a layout that includes both characters and lines, and the line layout display that displays a layout that includes only lines. It is. 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 virtual switch 540 is in the illustrated state.

That is, in normal layout display, a logical sum 542 of text layout display data 534 and line layout display data 536 is taken to create a dot pattern 5.
44 will be performed. When the virtual switch 542 is in the opposite state as shown, that is, in the case of displaying the grid layout, only the data 53B for displaying the grid layout is converted into a dot pattern. These dot pattern data are displayed on the layout display screen 5 of the display data storage area 330.
It is accumulated in the area corresponding to 04. 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 in a blinking manner 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 560, 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 562 in the figure. The pixel pattern of the line segment 582 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 564 and 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 FIG. 14, the key line 568 in the upper right corner of the table is the 4-bit code
It is expressed as the logical sum r0110J of IOJ 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, these line display data are handled in the system internal memory as follows:
It is advantageous to use a unit of arithmetic processing, that is, a 4-bit unit, and to use an 8-bit unit, that is, a byte, for pumping in an external storage file.

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 line indicated by the cursor key 588 operated while holding down the control key 584. Find the part that does not match the direction. Set the calculation result as the key line data at the currently specified cursor position574),
It is written in the corresponding storage position of the line display data storage area 322 as the line data at the new cursor position. Therefore, the same line data is always output for the same cursor key data. Based on the thus created line data, the pixel pattern of the line segment 562 is read out from the character pattern storage area 304 and output to the display section 24, printing section 22, etc.

For example, suppose that the cursor is located at the highlighted line portion 576 in FIG. 14 and the upward cursor key is operated. 18th A
From the figure, control passes through jump symbol 11 to diagram 1BB. The key line data captured in step 578 is
rllQOJ. Therefore, in step 580,
The key line data currently input using the cursor keys is “100”.
0'' and exclusive OR r0100J is taken, and this becomes the key line data at the new cursor position (5B2),
In other words, 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 cursor 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 cursor data at the current cursor position r010
It is logically ORed with 0J, r 00004, and the Kay line is eliminated. In this way, the control key 5B4 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. 17(A) to 17(E), in which reference numeral 530 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, the printing types are normal printing, sequential printing, and mid-stop printing. There are 3 types. These are keyboard 10
This can be selectively specified using a specific key. For printing and editing formats, see paper size,
Line spacing, one-character spacing, vertical/horizontal writing, etc. can also be specified using specific keys. Regarding paper size, A4
and B5 can be selected. Regarding the character spacing, the gap between the dot forming areas of two adjacent characters is, for example, 0.28a+m, 0.56mm, and 1.41t.
You can choose from three types: +w, and for line spacing,
If the gap between the dot forming regions of two adjacent rows is, for example, 0.85+am, 2.98+sm, and 5.0
There are three types of 8m layers to choose from.

These format conditions are determined by the control of the format creation section 416 of the print control section 1 20 for the printing format, and by the control of the editing section 16 and the left and right end display control sections 31B of the display control section 26 for the editing format. Can be changed in input mode. When changing the print mode, data regarding the selected line spacing, 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 you select sequential printing and mid-stop printing modes.

You can make selections for items other than paper size. Therefore, input data can be edited with the line spacing and character spacing selected during normal printing, and sequential printing or mid-stop printing can be selected to print with a different line 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 as Yokogata size, 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 41B.

As you will see, the keyboard 10 allows you to set the print type, paper size, line spacing, character spacing, and vertical/horizontal writing. These configuration data are
0 stored in the code data storage area 216 for now.
When normal printing is selected, the editing unit 16 and the format creation unit 41B import these setting data and set the format data for both printing and editing by printing 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 41B 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, the head transfer control section 408 feeds the print head of the printing section 22 by a pitch corresponding to the above-mentioned predetermined amount, and the paper feed control section 404 feeds the print head of the printing section 22 by a pitch corresponding to the above-mentioned predetermined amount. Feed the recording paper.

When sequential printing or stop printing is selected, the line spacing,
The printing format is changed according to the 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 a digit position on the editing screen 500 corresponding to the current position of the print head of the printing unit 22 by operating a specific key on the keyboard 10, and the cursor is displayed at the current digit position of the print head. It is a machine that combines. Further, head skip moves the print head of the printing unit 22 to a position corresponding to the digit position of the cursor displayed on the editing screen 500 of the display unit 24 by operating a specific key on the keyboard 10, and This function adjusts the position of the print head to the position of the print head. At this time, the digit position of the print head is calculated based on the character spacing set for printing.

The print head is moved in the left-right direction in units of one full-width character in the full-width input mode, and in units of one half-width character in the half-width input mode, based on the character spacing set for printing. The feeding of the recording paper, that is, the line advance and the nine line return are calculated in units of the line spacing set for printing, and can be fed in the forward and reverse directions. The movement of these print heads, and line feed/line return are controlled by a head movement control unit 402 and a paper feed control unit 404, respectively, in accordance with the operation of specific keys on the keyboard 10.

More specifically, the cursor skip is performed using the character spacing data 600 stored in the code data storage area 21B and set for printing, as conceptually shown in FIG. and data 8 at the 7 dot position from the head transfer control unit 402 to the current print.
Calculate the current print head digit position from 02 (804)
. As can be seen from FIG. 17, in this embodiment, the cursor 530 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 (8H) and supplies the updated cursor position data to the cursor display area 506. A specific operational flow of such cursor skip processing is shown in FIG.

As conceptually shown in FIG. 21, the head skip is an operation performed by the head transfer control unit 402 based on character spacing data 600 set for printing stored in the code data storage area 216 and cursor display control. The dot position to which the print head is to be moved is calculated from the current cursor position data 810 from the section 312 (812). The head dot position is also calculated based on the number of dots in the half-width character width.

The head transfer control unit 402 uses the calculated head movement dot position and the current head dot position data 602.
calculates the amount by which the print head should be moved (814), and controls the head transfer section 61B accordingly to move the print head of the printing section 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. A direction movement is instructed, and a leftward movement of the print head is instructed by simultaneous operation of the control key 5B4 and the non-conversion key 622. 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-width/half-width mode information 624 (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 "l" for half-width, then the logical formula for Full-width character dots (character spacing for printing) / (full-width/half-width mode information +1
) is calculated.

The number of dots to be moved and the direction of movement thus calculated are given to the head transfer section 81B, whereby the print head of the printing section 22 is moved. 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 802. A specific operational flow of such head transfer processing is shown in FIGS. 24A and 24B.

Referring to FIG. 25, paper feeding control performed by the paper feeding control unit 404 is conceptually shown. In this embodiment, line feeding is instructed by operating the paper feeding key 632 on the keyboard 10, and the control key Line return is instructed by simultaneous operation of 5θ4 and paper feed key 632. In response to this, the paper feed control unit 404 controls the paper feed (
Calculate the paper return amount (I (34). Calculated paper feed (
The paper feed (return) amount and paper feed (return) direction are determined by the paper feed (return) section 63.
6, and paper feeding to the printing section 22 is performed accordingly. Therefore, the recording paper is fed (returned) in the specified direction in one paper feed (return) section according to the set printing line spacing. FIG. 26 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 10 is operated, mid-stop printing is started, and the character from the current cursor position to the character immediately before the print stop character is printed, and then the print operation is changed to middle + h L, then the character is ＋ - Human power is 0 ■ It becomes a state of ability. If there is no print stop character, the page will be printed up to the end, and the same situation will occur. The print stop character is entered manually using a specific key, and a specific mark such as "S" surrounded by a hexagon is displayed on the display section 24. Print stop characters are not printed.

By creating a document that includes print stop characters and repeating printing start midway, stopping printing manually for one character, and starting print 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.

Midway stop printing is mainly controlled by the print mode control unit 400° format creation unit 41B and text development unit 408, and the pattern thereof is conceptually shown in FIG. 27.

The current head position data 850 and the left and right edge data 844 create a line format, that is, left and right edge information for printing of the line (84B). According to this line format, text data 840 including the print stop character is expanded into text from the current cursor position, that is, the expansion start character address (842).

The expanded text data is processed by the print processing unit 85B that stops midway.
given to. Here, if the print type 84B specifies mid-stop printing, the print stop character is replaced with a full-width space, and the expanded data is sequentially sent to the print data output unit 660.
supply to.

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 858. On the other hand, the line data development section 654 receives the line data 652 and the left and right edge information for printing, and forms the 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.
60. In this way, the print data output unit 880
Intermediate stop F printing shop FI! The characters of the text related to IL4 in part 85B are sequentially output to the printing part 22, and when the print stop character reaches two characters, a print stop character 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
In the print area 870 of line 0, lines 20 to 29 are used to enlarge the print text of line 20 by 10 times vertically and horizontally, and the text of line 10 is enlarged 15 times vertically. The processing when an instruction to do this is given will be explained.

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

Therefore, the enlargement processing unit 430 calculates the maximum settable vertical enlargement magnification from the format information, enlargement information data, and current cursor line number (Ei?2). More specifically, first, the number of unexpanded lines remaining until the end of the page is determined. In this example, since the 20th line is set to be enlarged 10 times vertically and horizontally, the 20th to 23rd lines are consumed as enlargement. Therefore, the residual nonextendability is 1 in lines 30 to 40.
It is one 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 (874), and the requested horizontal expansion magnification "10" is used as the horizontal expansion magnification (87B). This is registered in the expanded information table 680 along with the page number and line number (678). The third example of the registered contents of table 680 is
Shown in Figure 1. Based on the tables 8 and 110, the print data creation unit 424 creates print data by modifying the pattern data in the character pattern development area 422 and the C line pattern development area 418, and expands it into the printing unit 22. The pattern data is output and enlarged printing is performed. The specific operation flow of such enlarged printing processing is described in Section 32A.
It is shown in Fig. 32E.

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

Common characters available in these input modes are m'J
It is registered in the conversion dictionary 104 of the unit 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 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 subscript conversion, and by selecting the number, the Sentence M text, that is, 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 in the document floppy disk 28. Also, the external characters registered in the Bungo 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 2B. 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 you will see, when a specific key on the keyboard 10 is operated, the process shifts to the external character pattern creation work. The display unit 22 displays already registered external characters, 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 rlJ 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, information f(
10 and refers to the digit correspondence address table 532 to find the address of the character in the current cursor digit ([
190). Based on the obtained address information, the text data 640 is searched to obtain the code of the character corresponding to the address (8132).The font pattern is read from the character pattern generation section 522 using this code data, and the font pattern is read in the external character pattern storage area 696. Third, this is stored together with the registration number (894). Number key "2"
When you press , the external characters of the registration number "2" are changed.

In this embodiment, the registered capacity is 63 characters.

The layout display control unit 332 of the display control unit 26 reads the pattern information in the external character pattern storage area 886 into the display data storage area 330 and displays it on the layout display screen 504 of the display unit 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 each 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 69 is 1 on the layout screen 504.
It is displayed as a plink of the lower two dots (hatched portion in the figure) of the four pixel dots. This cursor 698 can also be moved using the cursor keys 566 on the keyboard 10. By operating a specific key on the keyboard 10, one pixel at the position of the cursor 69B 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 where ■ is created as a custom character pattern. If 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 by simple operations.

The device according to this embodiment may optionally include, for example, three
．． An external storage device 28 such as a 5-inch standard floppy 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, Keychain 10
A menu is displayed on the display section 24 as shown in FIG. 38 by operating a specific key. Therefore, the number +-r4J
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 the button is pressed, a display as shown in FIG. 39 is displayed, and five documents 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, they are a header section 700, a ledger section 702, a one-document area 704, and an external character section 70B. In the header section 700, 10, the maximum number of registered town moat documents, and the number of registered documents are recorded. Base Il
l at! In 702, a sentence 4g name written with a maximum of 10 characters, and format data such as paper size, line spacing, character spacing, vertical/horizontal writing format, etc. are stored. Literature area 70
4, information such as left edge, right edge, enlargement, and lines, and text are recorded for up to 20 documents. The external character section can accommodate up to 64 external characters.

Returning to FIG. 39, as shown in the kaidance area 502, if you operate either the cursor up or down key in this state, the document number display, that is, the identification display, shifts forward or backward one by one accordingly. In the embodiment, in the new registration mode, only document numbers without a document name are picked up, and in the registered update registration mode, only document numbers with a sentence δ name are picked up, 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 with a blank document name indicates that nothing is registered in that area. If you want to record the created document as an O, display this area without a document name and register it there.0 If you want to write the created document in an existing document Just register using that document number.

[-1 If you display the document number and operate a specific key, such as the new line key, you can operate the character keys and manually input 0. You can register the document by using the document name as is, or by modifying it and operating the line feed key again. It is not possible to register a document without even a single character entered as the document name.If the document currently being created is called from the floppy 28, that document name will be displayed first when registering. .

Such document registration control is mainly performed by the external storage control section 3.
This is done by 0. The situation is schematically shown in FIG. First, document information 71 being edited in the editing department 1B
The document number and document name are obtained from 0, and the document operation mode is determined from this (712). If the first bit of the document name data is "0", it is a new registration mode, and if the document name code exists, it is an existing registration mode. Enters registered document update mode.

A document ledger is read into the ledger section 702 of the floppy disk 28 or the storage section 1B, and from this ledger 702, the document name search section 714 searches for (717°, 718
