It also controls the code conversion unit 204 to perform code conversion, writes the code data to the input data storage area 202, and reads the code data.

The input data accumulated in the input data storage area is transferred to the input data discriminating unit 206 by an interrupt. here,
Depending on the shift and code of the code data, it is determined whether it is character data or function key data. The determined data is transferred to the input mode control unit 208, the full-width conversion unit 210, the Roman character conversion unit 212, and the function key conversion unit 214, and also to the code data storage area 216 according to the determination result. Accumulated.

There are basically two types of input modes for this device: a hiragana input mode and an alphanumeric / symbol input mode. Therefore, there is no Katakana input mode. This is because, as will be described later, when converting an input character string into kana-kanji characters in units of segments, the input character string corresponding to katakana is converted into katakana. In addition, the hiragana input mode includes a kana input method and a romaji input method. Regarding the character size, there are a full-width character input mode and a half-width character input mode. In addition, the system defaults to an insertion mode in which input data is sequentially inserted into text.

These input modes are controlled by the input mode control unit 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 present apparatus in accordance with the input mode data in the input data.

The full-width half-width converter 210 has a half-width character information storage area. This is provided with a table of characters that allows half-width characters, and the code data transferred to the code data storage area 216 is displayed in full-width character input mode or half-width character input mode instructed by the input mode control unit 208. , Half-width distinguishing information is added.

The Roman character conversion unit 212 has a Roman character information storage area, and in the Roman character input mode, the input data determination unit 206
Converts the character code data transferred from to the corresponding kana data. The converted kana data is stored in the code input data storage area 216.

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

The display unit 24 has three display screens, that is, an edit screen 500, a guidance display screen 502, and a layout display screen 504, as shown in FIG. The overall size of these screens is, for example, 472 dots horizontally and 64 dots vertically. In the edit screen 500, the text and the K-line can be displayed in full-width 17 characters, and the character string converted from the input character string into kana-kanji is displayed here, and the keyboard 10 is operated while performing the editing operation. be able to. In the display example shown in Fig. 7, the character strings "aiueo" and "kukeko" are all other wards, the same "ABCD" is half-width, and the same. Are displayed in the area 500 in double size.

The underline and the cursor are displayed on the edit screen 500, and the scale and the left and right ends are displayed in the scale display area 506. The cursor displayed on the edit screen 500 moves by the corresponding number of digits according to the full-width, half-width, double-width, and other attributes of the character at the current position. After the move, it occupies the first digit position of the move destination character.

The guidance display screen 502 also has a display capacity of 17 double-byte characters, and in the normal state, the input mode, the current position of the cursor (page, line, digit), paper size, maximum number of characters, maximum number of lines, full-width / half-width characters, etc. Is an area for displaying various guidances in text. For example, in the display example of Fig. 7, from the left, the hiragana input mode "flat", full-width input "all", paper size "A4", maximum number of characters "48 characters", maximum number of lines "40 lines", current position of the cursor " It shows the 1st page, 15th line and 20th digit.

The guidance display screen 502 also displays work guidance, error messages, and the like as necessary.
Further, the guidance selected on the guidance display screen 502 also includes candidates to be selected for single-kanji conversion, symbol input, external character input, English characters input in Roman character input mode, and enlargement size designation when setting enlarged characters. .

At the bottom of the guidance display screen 502, there is an area 508 for displaying printing conditions. Below the area 508, the printing conditions as shown in the figure are represented by characters and symbols 511, and correspondingly, a rectangular instruction mark 510 is instructed in the liquid crystal display screen area 508. As the print conditions, character spacing, line spacing, print type (mode), and the currently set states of vertical / horizontal writing are displayed. Wide, medium, and narrow can be displayed for the character spacing and line spacing, and normal printing, sequential printing, and half-stop printing can be displayed for the print modes. In the display example shown in FIG. 7, horizontal writing in normal printing is shown with a medium line spacing and character spacing.

The layout display screen 504 always displays the document format layout in this apparatus. One character is displayed with one dot, and the cursor position is displayed by blinking that dot. Further, the key line is also displayed as dots similarly to the character, but in this apparatus, there are a layout display mode in which both the character and the key line are displayed and a mode in which only the key line is displayed.

Such various displays are controlled by the display controller 26, and FIG. 4 shows a detailed functional configuration of the display controller 26. For example, various control units such as the character display control unit 302 perform a control operation for the code data stored in the code data storage area 216 according to the code data.

The character display control unit 302 reads the character pattern stored in the character pattern storage area 304 according to the text code data stored in the code data storage area 216,
It is transferred to the text display data storage area 306 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 a keyboard 10
When the double-width character is set by, the character at the current position of the cursor is double-sized and displayed on the display unit 24, and the cursor is moved to the next position. This double angle operation is identified by the function key conversion unit 214, and the code data storage area 2
Double angle display control unit 30 according to the code data stored in 16
Performed by 8. The double-width display control unit 308 reads full-width or half-width character pattern data from the character pattern storage area 304, expands each dot to one dot in the horizontal direction, and creates double-width pattern data. Store in 306.

The underline, cursor, key line, left and right edges of the paper (margin, scale), etc. are displayed respectively underline control unit 310, cursor display control unit 312, and key line display control unit.
314, and the left and right edge display control unit 316.
These display data are stored in the underline display data storage area 318, the cursor display data storage area 320,
It is accumulated in the key line display data storage area 322 and the scale display data storage area 324.

The display data accumulated in these display data storage areas 306, 318, 320, 322, and 324 are displayed by the display data creation unit 3
Combined at 26 and accumulated. The display data creation unit 326
It has a maximum storage capacity of one line for the text, key line, cursor, and scale data, that is, a maximum storage capacity of 104 digits in this embodiment.

Code data storage area 216 input from keyboard 10
The scroll instruction of the display screen stored in the display control unit 328 is fetched by the scroll control unit 328, and the latter is displayed in the display data generation unit 326.
The scroll information is added to the display data by giving a scroll instruction to. In this way, the display data corresponding to the display screen on the display unit 24 is formed by the display data creation unit 326 and accumulated in the display data storage area 330. The display data storage area 330 has a storage area corresponding to the display screen of the display section 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. The display data is corrected by correcting the contents of this VRAM copy, and the corrected data is transferred to the VRAM 114 all together.

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 the display data storage area 330.
Accumulated in. At that time, black-and-white inversion of the displayed characters is instructed to the guidance display control section 300 by the black-and-white inversion control section 336. The mark 510 indicating the printing condition is visualized by making the dot at the position of the printing condition notation 511 corresponding to the guidance control unit 300 black based on the input data on the printing condition from the input mode control unit 208 in a rectangular shape. To be done.

The layout display control unit 332 forms layout display data based on the accumulated data in the text display data storage area 306, the cursor display data storage area 320, and the key line display data storage area 322, and uses this to display data storage area 330. To store. Display data storage area 3
The display data accumulated in 30 is read to the display unit 24 via the VRAM changing unit 334 and displayed on the display unit 24.

By the way, the printing mode by the printing unit 22 includes normal printing,
There are three types of printing: sequential printing and halfway stopped printing. Normal printing is a mode in which all characters and key lines included from the beginning to the end of the current page are printed. In sequential printing, one sentence is printed when the device is in input mode and a line feed or page break is performed. That is, before the current position of the cursor, the closest character to the next line feed or page break, or if there is no line feed, the character from the beginning of the page to the current cursor position, or the most current character after the current cursor position The characters up to the next line break, page break, or end of page are printed.

This device can input a "print stop character" by a specific key. In the halfway stop printing, the character from the current cursor position to the character immediately before the print stop character or the end of the page is printed. After printing up to this point, the keyboard 10 returns to a state in which characters can be keyed.

Referring to FIG. 5, there is shown a detailed configuration of the print control unit 20 that performs such print control. The print control unit 20 has a print mode control unit 400. This is to read the input data from the code data storage area 216 and activate the print control unit 20. The print mode control unit 400 has a print mode storage area, instructs the print range control unit 406 to start the print mode control unit 406, moves the print head to the head transfer control unit 402, and feeds the paper feed control unit. For 404, each is instructed to feed paper.

The print range control unit 406 has a function of receiving the current position information of the print head from the head movement control unit 402 and the current position information 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 sent to the text expansion unit 408 and the key line data expansion unit 410. The text expansion unit 408 reads the text data from the text data storage area 412 in the code data storage area 216, calculates the print area, and expands it in the text expansion area inside.
At this time, in the vertical writing print mode, the vertical writing control unit 414
Determines whether the character is a 90 ° rotation prohibited character and adds rotation instruction information to it.

The transfer of the print head of the printing unit 22 is performed by the head transfer control unit 402.
Further, information indicating the current head position is input to the print range control unit 406. Further, the paper feeding mechanism of the printing unit 22 that feeds the recording medium is controlled by the paper feeding control unit 404 to control the forward feeding and the backward feeding of the recording paper.

The head transfer control unit 402 and the paper feed control unit 404 are under the control of the format creation unit 416. The format creation unit 416 takes in input information about the line spacing, the character spacing, and the left and right edges from the line spacing / character spacing storage area and the left / right edge information storage area of the code data storage area 216, and forms a print format. The line information is provided to the text expansion unit 408 and used for calculating the print area. The paper feed control unit 404 receives line spacing information from the format creation unit 416 and controls the paper feed direction and paper feed amount of the printing unit 22. Further, the head transfer control unit 402 receives the character spacing information from the format creating unit 416 and controls the feeding direction and the feeding amount of the print head.

The key line data expansion unit 410 has a key line data storage area, receives the print range information from the print range control unit 406, and outputs the key line pattern data to the key line pattern expansion area 418.
Expand to.

The text data expanded in the text expansion unit 408 is read by the character pattern acquisition control unit 420 and expanded in the character pattern expansion area 422 in the form of the corresponding pattern information read from the character pattern storage area 304. .

The character and the key line pattern developed in the character pattern development area 422 and the key line pattern development area 418 in this way are stored in the print data storage area 426 as print data according to the print format by the print data creation unit 424. At that time, the gap correction control unit 428 performs gap correction such as line-to-line printing and character-to-character printing for the print data stored in the print data storage area 426 so that the gaps between key lines and underlines are continuous. Similarly, the enlargement processing unit 43
When 0 is set, the pattern to be printed is enlarged so that the space between the lines is continuous or the space is enlarged. The expanded pattern data is expanded in the expanded data expansion area therein, and finally stored in the print data storage area 426.

The print data stored in the print data storage area 426 is supplied to the print head of the printing unit 22 and printed out.

By the way, FIG. 8 conceptually shows the pattern of the display control performed by the display control unit 26, focusing on the text display, the key line display and the layout display. As you can see, first, the text expansion data 520 for one line
Is developed, and the dot pattern 524 is developed by the character pattern generation 522. This is stored in the display data creation unit 326 as text display data. At that time, display data for scale, left and right edges, underline, cursor 52
6 is expanded in each corresponding area. In addition, one line of key line data 528 is expanded as key line display data.
These pieces of display data are stored in the display data storage area 330 after the data of 17 full-width characters after the position pointed by the scroll pointer 546 is cut off to obtain a logical sum 530.

As described above, in this device, the layout display screen 504
A page layout can be displayed. This is mainly executed by the layout display control unit 332, and an example of the operation flow is 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 flow charts, when 2 is added to the column counter, it advances only the full-angle position and 1
If you add, it will step forward only half-width position.

First, a digit correspondence address table 532 is created from the text expanded data 520 for one line, and layout display data 534 is formed based on this. In that case, the data for two digits is ORed and converted into 1 dot data (black) for display. Of course, the outside of the left and right margins, spaces, line feeds, and page breaks are converted into white dot data. Similarly 1
Layout display data 5 from the key line data 528 for the line
36 is formed.

As described above, in the present device, there are two types of layout display modes, which are a normal layout display that displays a layout including both characters and key lines, and a key line layout display that displays a layout that includes only key lines. Is. The virtual switch 540 is switched in the layout display mode 538. This switching is
This is performed in response to the function key of the keyboard 10 for selecting the layout display mode. Further, the size of the frame of the layout display screen is changed according to the sizes A4 and B5 of the selected paper. When the normal printing is selected and the character spacing or the line spacing is changed, the layout display is also changed.

When the virtual switch 540 is in the illustrated state, that is, in the normal layout display, the text layout display data 534 is the logical sum of the key line layout display data 536.
542 is taken and dot pattern creation 544 is performed. When the virtual switch 542 is in a state opposite to that shown in the figure, that is, in the case of the key line layout display, only the key line layout display data 536 is converted into the dot pattern. These key line dot pattern data are displayed in the display data storage area 33.
It is stored in the area corresponding to the layout display screen 504 of 0. Such an operation is executed for each row, and the layout display dot data for one page is expanded in the layout area. The dot at the current position of the cursor is blink-displayed on the layout display screen 504.

In this embodiment, since the two layout display modes can be selected in this manner, the overall layout can be easily grasped, and the entire configuration of the key lines can be easily confirmed if necessary, and the layout display is easy to see. Will be provided.

The K-line displayed on the edit screen 500 is displayed in four directions of up, down, left, and right from the center of the full-width character display area 560 as shown in FIG. 13, which are the basic constituent elements that are the minimum constituent units of the K-line, That is, it constitutes a K-line segment. In the figure, these four key line segments are designated by the reference numeral 562. The pixel pattern of the key line segment 562 is accumulated in the character pattern storage area 304. In the present embodiment, the key line display data is formed by the key line display controller 314 in response to the simultaneous operation of the control key 564 of the keyboard 10 and the cursor movement key 566 (FIG. 15).

As shown in FIG. 13, one key line display data is composed of a 4-bit code indicating up, down, left and right directions. Therefore, in the key line display data storage area 322, these 4
Key line display data is stored in the form of the logical sum of bit codes. For example, as shown in FIG. 14, the K-line 568 in the upper right corner of the table is the 4-bit code “0010” and “010”.
It is represented by the logical sum “0110” of “0”. In this way
All patterns of the K-line can be represented by a 4-bit code. With the minimum unit of 1 byte of data handled in the system, it is possible to operate the tee line for 2 full-width characters. Therefore, it is advantageous that these K-line display data are handled in the system internal memory in units of arithmetic processing, that is, in units of 4 bits, and in the external storage file in units of 8 bits, that is, in units of 1 byte. .

As shown in FIG. 15, the key line display control unit 314 takes in the current cursor position (570), reads the key line data at that position from the key line display data storage area 322, and attempts to newly set it. The exclusive OR with the K-line data is calculated (572). That is, the part where the key line data at the current cursor position does not match the direction indicated by the cursor key 566 operated while pressing the control key 564 is obtained. The calculation result is set as the key line data at the cursor position designated this time (574), and is written in the corresponding memory position of the key line display data storage area 322 as the key line data at the new cursor position. Therefore, the same key line data is always output for the same cursor key data. The pixel pattern of the key line segment 562 is read from the character pattern storage area 304 based on the key line data created in this way, and is output to the display unit 24, the printing unit 22, and the like.

For example, if the cursor is on the K line part 576 in Fig. 14,
Suppose you have operated the upward cursor key. From FIG. 16A, control transfers to FIG. 16B via jump symbol 11. The key line data captured in step 578 is "1100". Therefore, in step 580, the exclusive OR "0100" with the key line data "1000" currently input with the cursor key is obtained, and this becomes the key line data at the new cursor position (582). That is, an upward key line is formed.

Since such an exclusive OR is taken, when the cursor is moved to the position where the key line is, the part of the key line that coincides with the moving direction of the cursor is erased. For example,
When the key line data at the character position immediately below the current cursor position is "0100" and the down cursor key is operated with the control key, the key input data "01
The logical sum "0000" of "00" and the key line data "0100" at the current cursor position is taken, and the key line is erased. In this way, by operating the control key 564 and the cursor key 566 at the same time, it is possible to set and delete the key line.

Various examples in the case where the cursor is moved to the right to form the key line are shown in FIGS. 17 (A) to 17 (E). In the figure, reference numeral 59
0 indicates the cursor display.

In this embodiment, by adopting such a configuration of the key line data, it becomes possible to efficiently store the key line data and perform high-speed processing.

As described above, in the present embodiment, the print type is normal print,
There are three types: sequential printing and halfway stopped printing. They are,
It can be selectively designated by a specific key of the keyboard 10. Also, regarding the format for printing and editing,
Paper size, line spacing, character spacing, vertical / horizontal writing, etc. can also be specified with specific keys. A4 and B5 can be selected for the paper size. Regarding the character spacing, the gap between the dot formation areas of two adjacent characters can be selected from three types of, for example, 0.28 mm, 0.56 mm, and 1.41 mm. The gap between the dot formation areas is 0.85 mm, 2.
You can choose from 96 mm and 5.08 mm.

Such format conditions are controlled by the format creation section 416 of the print control section 20 for the print format, and left and right display control sections of the editing section 16 and the display control section 26 for the edit format.
It can be changed in the input mode by controlling the 316. When the print mode is changed, 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, selection can be made for all items including the paper size. Also, the selected item is reflected in both the print and edit formats, and the text and layout are reedited accordingly. When the sequential printing or the halfway stopped print mode is selected, selection can be made for items other than the paper size. Therefore, it is possible to edit the input data at the line spacing and character spacing selected during normal printing, and select sequential printing or halfway printing to print at a different line spacing and / or character spacing. The selected item is reflected in the print format and does not affect the editing.

Further, the set print conditions, particularly the items of the print conditions that can be temporarily changed in this way, are controlled by the guidance display control unit 300 as described in detail above, and line spacing, character spacing, print type and vertical・ Horizontal writing, paper size,
The maximum number of characters and the maximum number of lines are displayed in the areas 508 and 502 of the display unit 24. Since the printing conditions are constantly displayed in this way, the burden on the operator is reduced, and the chances of printing errors and reprinting are reduced.

FIG. 18 conceptually shows the outline of the format changing operation performed by the editing unit 16 and the format creating unit 416. As can be seen from the figure, the keyboard 10 can set print type, paper size, line spacing, character spacing, and vertical / horizontal writing items. These setting data are temporarily stored in the code data storage area 216. When the normal printing is selected, the editing unit 16 and the format creation unit 416 take in these setting data and output both the format data for printing and the format data for printing, the paper size, the line spacing, the character spacing, and the vertical / vertical format. You can change each item in horizontal writing. The editing unit 16 re-edits the text and layout according to the changed data. The format creation unit 416 changes the text data of the text development unit 408 for printing, and also changes the control data of the head transfer control unit 402 and the paper feed control unit 404. Therefore, the head transfer control unit 40
8 feeds the print head of the printing unit 22 by the pitch corresponding to the above-mentioned predetermined amount, and the paper feed control unit 404 feeds the recording paper of the printing unit 22 by the pitch corresponding to the above-mentioned predetermined amount. .

If sequential printing or halfway printing is selected, line spacing,
The print format is changed according to the character spacing and vertical / horizontal writing information.

By the way, this device has a cursor skip function and a head skip function. Keyboard skip
A function of moving the cursor to a digit position on the edit screen 500 corresponding to the current position of the print head of the printing unit 22 by operating a specific key in 10 and adjusting the display position of the cursor to the current digit position of the print head. . In addition, the head skip,
By operating specific keys on the keyboard 10, the display
This is a function of moving 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 24 and adjusting the position of the print head to the display position of the cursor. At that time, the digit position of the print head is calculated based on the character spacing set for printing.

The horizontal movement of the print head is performed in full-width one-character units in the full-width input mode and in half-width one-character units in the half-width input mode based on the character spacing set for printing. The feeding of the recording paper, that is, the line feed / line return is calculated in the unit of the line spacing set for printing, and can be fed in the forward direction and the backward direction. The transfer of these print heads and the line feed / line return are controlled by the head transfer control unit 402 and the paper feed control unit 404, respectively, according to the operation of specific keys of the keyboard 10.

More specifically, the cursor skip is the data 600 of the character interval set for printing, which is stored in the code data storage area 216, as conceptually shown in FIG. 19 of the operation performed by the cursor display control unit 312. And the head transfer control unit 4
The current print head digit position is calculated from the current print head dot position data 602 from 02 (604). As can be seen from FIG. 17, since the cursor 590 has a length corresponding to the half-width character width in this embodiment, the cursor digit position is also calculated in units of the half-width character width. The cursor display control unit 312 updates the cursor position data in the cursor display data storage area 320 based on the calculated current head digit position (60
6), updated cursor position data in the cursor display area
Supply to 506. FIG. 20 shows a specific operation flow of such cursor skip processing.

As for the head skip, as conceptually shown in the 21st operation of the head transfer control unit 402, the data 600 of the character interval set for printing accumulated in the code data storage area 216 and the cursor display control unit. The dot position of the print head movement destination is calculated from the data 610 of the current cursor position from 312 (612). The calculation of the head dot position is also performed based on the number of dots of the half-width character width. Based on the calculated head movement dot position and the current head dot position data 602, the head transfer control unit 402 calculates the amount of the print head to be transferred (614), and controls the head transfer unit 618 accordingly. The print head of the printing unit 22 is moved by the calculated amount. If the calculated value is positive, it moves to the right, and if it is negative, it moves to the left. At the same time, the current head dot position data 602 in the head position data storage area is updated. A specific operation flow of such head skip processing is shown in FIG.

In this way, in this embodiment, the correspondence between the print start position on the printer and the cursor display position on the document edit screen can be grasped by a simple operation. Therefore, the operation efficiency when printing or editing is improved, and the burden on the operator is reduced.

Referring to FIG. 23, head transfer control performed by the head transfer control unit 402 is conceptually shown. In this embodiment, the control key 564 of the keyboard 10 and the space key 620 are simultaneously operated to instruct the print head to move to the right, and the control key 564 and the non-conversion key 622 are simultaneously operated to instruct to move the print head to the left. It In response to this, the head transfer control unit 402 calculates the head movement amount from the printing character interval data 600 and the full / half-width mode information 624 (626).

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

The number of moving dots and the moving direction calculated in this way are given to the head transfer unit 616, whereby the print head of the printing unit 22 moves. Therefore, when the full-width mode is designated, the print head moves in units of full-width character width, and when the half-width mode is designated, the print head moves in units of half-width character width. Also, new head dot position data
It is also stored in the head position data storage area as 602. A specific operation flow of such head transfer processing is shown in FIGS. 24A and 24B.

Referring to FIG. 25, the paper feed control performed by the paper feed controller 404 is conceptually shown. In this embodiment, line feed is instructed by operating the paper feed key 632 of the keyboard 10, and line return is instructed by simultaneous operation of the control key 564 and the paper feed key 632. In response to this, the paper feed control unit 404
A paper feed (return) amount is calculated from the line spacing data for printing 630 (634). The calculated paper feed (return) amount and paper feed (return) direction are given to the paper feed (return) unit 636, and the printing unit 22 feeds paper in accordance with this. Therefore, the paper feed (return) of the recording paper is performed in the designated direction by the paper feed (return) amount according to the set printing line interval. FIG. 26 shows a specific operation flow of such paper feeding processing.

By the way, this apparatus can use the halfway stop printing mode. In this mode, while printing the text data in which the print stop character is input, if the print position approaches the print stop character included in the text data, the printing operation is interrupted and the edit state is restored.

More specifically, when a specific key on the keyboard 10 is operated, halfway stop printing is started, the characters from the character at the current cursor position to the character immediately before the print stop character are printed, and then the printing operation is stopped and the character is pressed. Input is ready. When there is no print stop character, the page is printed up to the end,
It will be in the same state. The print stop character is input by a specific key, and the display unit 24 displays a specific mark, for example, "S" surrounded by a hexagon. Print stop characters are not printed.

By creating a document containing print stop characters and repeating print start, print stop, character input, print start,
It is possible to efficiently output a plurality of text documents, some of which are different but most of the others are the same.

The halfway stopped printing is mainly controlled by the print mode control unit 400, the format creation unit 416 and the text development unit 408, and the pattern thereof is conceptually shown in FIG. A line format, that is, left and right end information for printing of the line is created by the current head position data 650 and left and right end data 644
(646). The current cursor position, according to this line format,
That is, the text data 640 including the print stop character is text expanded from the expansion start character address (642).

The expanded text data is given to the midway stop printing processing unit 656. Here, when the print type 648 specifies halfway stopped printing, the print stop character is replaced with a double-byte space, and the expanded data is sequentially supplied to the print data output unit 660.

The text expansion 642 also creates a digit-corresponding address table from the expansion start character, and the address of the print stop character included in the text line is given to the key line data correction unit 658. On the other hand, the key line data expansion unit 654 is given the key line data 652 and the left and right edge information for printing, and key line data from the expansion start character to the digit position including the print stop character is formed. The key line data correction unit 658 supplies the key line data up to immediately before the print stop character to the print data output unit 660. In this way, the print data output unit 660 sequentially outputs the characters of the text developed in the halfway stopped print processing unit 656 to the printing unit 22, and when the print stop character is reached, outputs the print stop command. At this point, the system is in a state where characters can be keyed in from the keyboard. 28A and 28B show a specific operation flow of such a halfway stopped printing process.

In this embodiment, in this way, by including a specific control character, that is, a print stop character, in the document text, halfway stop printing can be performed. By this, imprint printing that prints characters at a predetermined position on a predetermined form,
Merge printing is realized without external storage, complicated functions, or operations.

By the way, in this apparatus, a character font can be enlarged and printed as one of emphasized characters such as underline and double-width characters. The enlargement size can be set on a line-by-line basis with respect to the line at the current cursor position, and in this embodiment, it can be enlarged up to 24 times in the vertical and horizontal directions by an integral multiple. It is not enlarged on the edit screen 500 and layout screen 504 of the display unit 24, but enlarged on the printing unit 22. As a result of the enlargement, if the size of the recording paper exceeds the size of the recording paper, the size of the recording paper is reduced accordingly.

Such character font enlargement control is executed by the enlargement processing unit 430 of the print control unit 20 on the print data of the print data creation unit 424. In order to make this easier to understand, as shown in Fig. 29, lines 20 to 29 are used in the print area 670 with a maximum of 40 lines, and the print text on line 20 is multiplied by 10 times in the vertical and horizontal directions. 10th in the enlarged state
The process when the instruction to vertically enlarge the text of the line 15 times is given will be described.

With respect to this example, the enlargement processing unit 430 performs the processing conceptually shown in FIG. First, the enlargement processing unit 430
Import the maximum number of lines "40" set as format information,
The enlargement information of each line is fetched as the enlargement information data. In this case, data indicating that the 20th row is designated to be magnified 10 times vertically and horizontally is fetched. The operator
If you use the keyboard 10 to position the cursor on the 10th line and give the text an instruction to request a magnification of 15 times vertically and 10 times horizontally, these data, the current cursor line number "10 ], The required vertical enlargement ratio “15” and the required horizontal enlargement ratio “10” are fetched.

Therefore, the enlargement processing unit 430 calculates the maximum vertical enlargement ratio that can be set from the format information, the enlargement information data, and the current cursor line number (672). More specifically, first, the number of unexpanded lines remaining up to the end of the page is calculated. In this example,
Since the horizontal and vertical magnification of 10 times is set in the 20th row, the 20th to 29th rows are consumed as the enlarged rows. Therefore, the remaining non-expanded lines are 11th lines from 30th line to 40th line. If the 10th line to be enlarged is added to this, the maximum number of lines permitted for enlargement, that is, the maximum magnification is "12".

Next, the maximum magnification "12" is compared with the required vertical magnification "15", and the vertical magnification is corrected to "12" within the maximum magnification limit (674). The required lateral enlargement factor "10" is used as the lateral enlargement factor (676). This is registered in the expanded information table 680 together with the page number and line number (678). An example of the registered contents of the table 680 is shown in FIG. Based on this table 680, the printing data creation unit 424 corrects the pattern data in the character pattern development area 422 and the key line pattern development area 418 to create printing data, and prints the enlarged pattern data in the printing unit 22. Output and enlarge print. FIG. 32A shows a specific operation flow of such enlarged print processing.
Shown in Figure 32E.

Supplementing the explanation of this operation flow a little, the guidance display screen 502 displays vertical and horizontal magnifications. For this magnification, a predetermined number is displayed as a default value,
Either the vertical or horizontal magnification, which is highlighted, can be corrected and set with 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.

As described above, in the present embodiment, it is possible to set the enlargement size of the character font for each line and print with the enlarged font. Therefore, the enlarged character can be printed by a relatively simple operation.

In this embodiment, as described above, the hiragana input mode and the alphanumeric / symbol input mode can be used as normal character input other than control characters. In Hiragana input mode, you can use kana-kanji conversion, katakana conversion, and single kanji conversion for each phrase.
The Kana-Kanji conversion uses the latest learning method. Non-Kanji characters such as special symbols are entered in alphanumeric / symbol input mode. Since these details are not directly related to the understanding of the present invention, description thereof will be omitted.

General characters that can be used in these input modes are
It is registered in 16 conversion dictionaries 104. However, for characters, symbols, figures, etc. that have not been registered, a font can be created by this device and input as external characters. The font is created using the layout screen 504. It is also possible to call a font that has already been registered to the edit screen 500, copy it to the layout screen 504 (copy external character), modify it, and use it, or use the same font as an external character without modification. it can. It is also possible to newly create a blank page.

The created external character is displayed along with the candidate number on the guidance screen 502 as in the case of single-kanji conversion, and by selecting the number, the document text, that is, the edit screen 500 is displayed.
Can be entered in. In the example shown in FIG. 35, two external characters have already been registered for the numbers "1" and "2". The created external character can be registered in the document floppy 28. The external characters registered in the document floppy 28 are read into the storage unit 18 and used.

The external character creation process is mainly performed by the input control unit 12 and the display control unit 26. FIG. 33 conceptually shows the processing for correcting the text characters already displayed on the edit screen 500 and registering them as external characters.

As can be seen from this, when a specific key of the keyboard 10 is operated, the external character pattern creating operation is started. Display 22
The registered external characters are displayed in, for example, as shown in FIG. Therefore, if it is newly created, "3" to "8" are selected by the number keys. If it is the correction of the registered pattern, "1" or "2" is selected.

Select the external character copy by operating a specific key (external character key). The thirty-fourth example of the operational flow for copying an external character is shown. Next, for example, when the number key “3” is operated in the example of FIG. 35, in response to this operation, the information 610 of the current cursor digit position is first fetched and the digit corresponding address table 532 is referred to the current cursor digit. Find the address of a character (690). Search text data 640 based on the obtained address information,
Get the character code corresponding to the address (692). With this code data, the font pattern is read from the character pattern generator 522, and the external character pattern storage area 69
This is stored in the third of 6 together with the registration number (694). When the number key "2" is pressed, the external character of the registration number "2" is 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 of the external character pattern storage area 696 into the display data storage area 330 and displays it on the layout display screen 504 of the display unit 24.

The correction of the font called on the layout screen 504 or the creation of the external character pattern from a blank sheet is performed as follows. The layout screen 504 has four horizontal and four vertical lines in this embodiment.
Eight dots are displayed, and one pixel in the character font is represented by a rectangle of two dots each in the vertical and horizontal directions. As shown in FIG. 36, on the layout screen 504, the cursor 698 is displayed by blinking the lower half 2 dots (hatched portion in the same figure) of 4 dots per pixel. This cursor 698 can also be moved with the cursor key 566 of the keyboard 10. Cursor by operating specific keys on keyboard 10
One pixel at the 698 position can be black or white.
When this particular 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. 37th
The figure shows a state in which is created as an external character pattern.
When a specific key is operated in this state, an external character is registered at the corresponding number, that is, the position "3" in the example of FIG.

As described above, according to this embodiment, the character displayed on the screen is copied to the external character area. Therefore, a desired external character can be created by a simple operation.

The device according to the present embodiment optionally has, for example, 3.
External storage device such as 5 inch standard floppy disk 2
8 can be connected. A document can be registered in the floppy 28 and the registered document can be retrieved. The floppy 28 can be used as a document floppy by initializing it.

Initialization is performed as follows. First, a specific key of the keyboard 10 is operated to display a menu on the display unit 24 as shown in FIG. Then, when the number key "4" is pressed, a confirmation message is displayed, and when a specific key is further operated, the initialization is executed. As a result, all the documents registered in the floppy 28 are cleared.

When the number key "2" is pressed in the menu display shown in FIG. 38, a display as shown in FIG. 39 is displayed, and the document can be registered in the floppy 28.

Data is recorded on the floppy 28 in the format shown in FIG. 40 in this embodiment. That is, the header part
Reference numeral 700 denotes a ledger portion 702, a document area 704, and an external character portion 706. The header section 700 records the ID, the maximum number of registrable documents, and the number of registered documents. The ledger unit 702 stores a document name described with a maximum of 10 characters and format data such as paper size, line spacing, character spacing, and vertical / horizontal writing format. In the document area 704, information such as the left end, the right end, enlargement, and key line, and a text of up to 20 documents are recorded. Up to 64 characters can be stored in the external character section.

Returning to FIG. 39, as shown in the guidance area 502,
If you operate any of the cursor up / down keys in this state,
Accordingly, the display of the document number, that is, the identification display is shifted back and forth one by one. In the present embodiment, only the document number without the document name is picked up in the new registration mode, and only the document number with the document name is picked up in the already registered update registration mode, and rotated and displayed in response to the cursor up / down keys. Already registered update In registration mode,
When the 20th document is shifted, if the down shift key is further operated, it returns to the 1st and then returns to the display of the document name of the first registered document number. Similarly, if you shift to the first document, press the upper shift key
It returns to the 20th and then the document name of the last registered document number is rotated.

A document number with a blank display of the document name indicates that nothing is registered in that area. When registering the created document, an area without such a document name is displayed and registered in this area. When the created document is overwritten on the existing document, the existing document name may be found and registered with the document number.

When the desired document number is displayed and a specific key, for example, the line feed key is operated, the character key is operated to enter the document name. The document can be registered by inputting the document name, using the document name that has already been called, or correcting it and then operating the line feed key again. It is not possible to register without entering one character as the document name. If the document currently being created is called from the floppy 28, the document name is first displayed at the time of registration.

Such document registration control is mainly performed by the external storage control unit 30.
Done by. This situation is conceptually shown in FIG. First, the document number and the document name are obtained from the document information 710 being edited by the editing unit 16, and the mode of the document operation is determined (712). If the first bit of the document name data is "0", the new registration mode is set, and if the code of the document name exists, the registered document update mode is set.

The document ledger is read from the ledger unit 702 of the floppy 28 to the storage unit 18, and the document name search unit 714 from the ledger 702 is a document (717,718) document according to the cursor up / down keys 720 and 722 keyed from the keyboard 10. Search for a number. At that time, in the new registration mode, only the document number of which the leading data of the document name is “0” is picked up, and in the already registered update registration mode, only the document number having the document name is picked up.

The document number and document name picked up in this way are
It is converted into a corresponding character font pattern and displayed on the display unit 24. A specific operation flow of the document name search processing in such document registration is shown in FIGS. 42A to 42B.

When the document registered in the floppy 28 is called, the menu shown in FIG. 38 is displayed, and the numeric key "1" is operated to display the menu shown in FIG. As in the case of registration, operate the cursor up / down keys 720 or 722 to rotate and display the desired document name, and then operate the line feed key with the desired document name displayed to call the registered document. .

According to the present embodiment, in this way, the document registration area in the external storage device is distinguished between the registered document and the unregistered document, only the unregistered area is displayed in the new registration mode, and the registered area in the registered document update mode. Show only. This display is
Rotated by operating the cursor up / down keys 720 and 722. By thus limiting the selection range of the registration operation, the chance of an operation error such as accidentally deleting a registered document or rewriting it to another document is reduced.

Effect According to the present invention, since the two layout display modes can be selected in this way, the entire layout can be easily grasped, and the entire configuration of the ruled lines can be clearly confirmed if necessary, and the layout is easy to see. Display is provided.
