Abstract

PURPOSE:To avoid such a case where a registered document is deleted by mistake or rewritten to another document by displaying only an unregistered area in a new register mode and only a registered area in a registered document updating mode respectively. CONSTITUTION:Both the number and name of a document are obtained from the document information 710 which is under editing at an editing part 16. Then it is decided from the head bit of the document name data whether those document number and name are equal to the new register mode or the existing register mode. Then only an unregistered area is displayed when the document register area of an external memory (floppy 28) is set in a new register mode. While only a registered area is displayed on a registered document updating mode. These displays can be rotated with operation of a cursor up-down key. Thus it is possible to decrease the operating mistakes where a registered document is deleted by mistake or rewritten to another document by limiting a selection range for registering operations.

The guidance display screen 502 also has a display capacity of 17 full-width characters, and in the normal state, the input mode, current position of the cursor (page, line, column), paper size, maximum number of characters,
This is an area where various guidance such as maximum number of lines, full-width/half-width, etc. is displayed in text. For example, in the display example shown 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 "
40th line”, cursor current position rlJ page “15” line “2”
0” digit is shown.

Further, the guidance display screen 5G2 displays work guidance, error messages, etc. as necessary. Furthermore, single kanji conversion and symbol input.

The guidance display screen 502 also displays candidates selected when inputting non-standard characters, alphabetic characters input in the Roman alphabet input mode, designation of enlargement size when setting enlarged characters, and the like.

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),
0 character spacing and line spacing can be displayed as wide, medium, or narrow, respectively, and the print mode can be displayed as normal printing, sequential printing, or intermediate printing. 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 apparatus. 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 28, and FIG. 4 shows a detailed functional configuration of the display control section 2B. For example, various control units such as the character display control unit 302 perform control operations corresponding to the code data stored in the code data storage area 21B.

The character display control unit 302 controls the code data storage area 21
According to the text code data accumulated in 6.

The character patterns stored in the character pattern storage area 3G4 are read out and displayed on the display section 24. For example, it is transferred to the text display data storage area 30B as display data such as a dot pattern.

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 performed by the double-angle display control unit 308 according to the code data identified by the function key conversion unit 214 and stored in the code data storage area 21B.
1308 reads double-width pattern data from the character pattern storage area 304 and stores it in the text display data storage area 30B.

The display of the angline, cursor, key line, left and right edges of the paper (margins, scale), etc. is 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 32
2. 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 the display data generation unit 32B, and the accumulated 0 display data generation unit 326 generates a maximum of one line of text, line, cursor, and scale data. That is, this embodiment has a maximum storage capacity of 104 digits.

Code data storage area 2 input from keyboard IO
The scroll instruction for the display screen stored in 16 is taken into the scroll control section 328, and the latter gives the scroll instruction to the display data creation section 32B to add scroll information to the display data. In this way, the display data corresponding to the display screen on the display unit 24 is transferred to the display data creation unit 32.
Formed at B.

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). Copying to this VRA is to hold data to be displayed on the display unit 24. Modification of the 0 display data is performed by modifying the contents of this VRAM copy, and the modified data is transferred to the VRAM 114 all at once. be done.

The character information displayed on the guidance display screen 502 is character display data from the single character display control section 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 one displayed character 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 signal is read out to the display section 24 via the AM changing section 334 and displayed on the display section 24 .

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

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

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 21B and start the print control section 20. Print mode control unit 400
has a print mode storage area, and a print range control unit 40
The paper feed control unit 404 instructs the head transfer control unit 8 to start the print head, and also instructs the head transfer control unit 102 to move the print head.
Instruct the paper feed for each.

The print range control unit 40B receives information on the current position of the print head from the head transfer control unit 402, and also receives information about the current position of the print head.

The cursor display control unit 312 has a function of receiving current position information of the cursor 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 40B is transmitted to the text development unit 408 and the line data development unit 4.
Sent to 10. The text development unit 408 reads text data from the text data storage area 412 in the code data storage area 21B, calculates a print area, and develops the text data into a text development area therein. At this time, if the print mode is vertical, the vertical writing control unit 414 determines whether or not the character is prohibited from being rotated by 90'', and adds one rotation instruction information to the character.

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 unit 4011. Further, the paper feeding mechanism that feeds the recording medium of the printing unit 22 has a paper feeding amount @f
i404, and controls forwarding and returning 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
6 takes in input information about line spacing, character spacing, and left and right edges from the line spacing/character spacing storage area and the left and right edge information storage areas of the code data storage area 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 41B,
Controls the paper feed direction and paper feed amount of the printing unit 22. Further, the head transfer system faM& 402 receives character spacing information from the format creation section 41B, and controls the feeding direction and feeding amount of the print head.

The line data development unit 41G has a line data storage area, receives print range' information from the print range control unit 408, and develops the line pattern data in the line pattern development area 418.

The text data developed in the text development section 408 is 2
The character pattern capture control section 420 reads out the information and expands it in the character pattern development area 422 in the form of the corresponding pattern information read out from the single character pattern storage area 3G4.

The characters and the line pattern developed in the character pattern development area 422 and the line pattern development area 41B are converted into print data according to the print format by the print data creation section 424 in the print data storage area 41B.
It is stored in 2B. that time.

The interval correction control unit 428 controls the print data storage area 421
Line spacing printing that continues the gaps between lines and angle lines for print data stored in 1.

Similarly, the enlargement processing unit 430, which performs spacing correction such as character amount printing, enlarges the pattern to be printed and performs enlargement processing such as making the line spacing continuous or expanding the space. The data is developed in the enlarged data development area therein and finally stored in the print data storage area 42B.

The print data stored in the print data storage area 426 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 2B, focusing on text display, gray line display, and layout display. As you will see, first, one line of text expansion data 52
0 is expanded, and a dot pattern 524 is expanded by character pattern generation 522. This is stored as text display data in the 1 display data creation section 32B. At this time, the display data 52B 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 54B is cut out, a logical sum 530 is taken, and the data is stored in the 1 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 move forward by a full-width position, and adding l causes it to move forward 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 538 is formed from one line of line data 528.

As mentioned above, this device has two types of layout display modes: normal layout display that displays a layout that includes both single characters and gray lines, and gray line layout display that displays a layout that includes only gray 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 depending on the size of the selected paper, A4 and B5. Furthermore, when normal printing is selected, changing the character spacing or line spacing also changes the layout display.

When the virtual switch 540 is in the illustrated state, that is, in normal layout display, the text layout display data 534 and the line layout display data 53B are displayed.
The logical sum 542 of the dot patterns is calculated to create a dot pattern 544. The virtual switch 542 is in a state opposite to that shown in the diagram,
That is, in the case of a line layout display, only the line layout display data 53B is converted into a dot pattern. These dot pattern data are stored in an area of the display data storage area 330 that corresponds to the layout display screen 504. 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 580, and this is the basic component that is the minimum constituent unit of the C line. In other words, it constitutes a wire segment. These four key line segments are designated by reference numeral 562 in the figure. The pixel pattern of the line segment 562 is stored in the character pattern storage area 304. In this embodiment, the line display data is formed by the line display control section 314 in response to simultaneous operation of the control key 564 and cursor movement key 566 (FIG. 15) of the keyboard 10.

As shown in FIG. 13, one line display data is composed of a 4-bit code indicating the up, down, left, and right directions. Therefore, the line display data is stored in the line display data storage area 322 in the form of the logical sum of these 4-bit codes. For example, as shown in Figure 14, the key line 568 in the upper right corner of the table is the 4-bit code r001.
It is expressed as the logical sum r0110J of 0J and rolooJ. In this way, all patterns of key lines can be expressed in 4-bit codes. One byte, the minimum unit of data handled within the system, can handle two full-width characters. Therefore, it is advantageous for these line display data to be handled in the system internal memory in units of arithmetic processing, that is, in the middle of 4 bits, and to be extracted in external storage files in units of 8 bits, that is, 1 byte. .

As shown in FIG. 15, the line display control unit 314 imports the current cursor position (570) and stores the line data at that position in the line display data storage area 32.
2 and calculates the exclusive OR of this and the new line data to be set (572), that is, the line data at the current cursor position and the value indicated by the cursor key 588 operated while holding down the control key 5B4. Find the part that does not match the direction. Set the calculation result as the key line data at the currently specified cursor position574),
The key line data for the new cursor position is written to the corresponding storage location in the key line display data storage area 322. Therefore, the same key line data is always output for the same cursor key data. Based on the thus created gray line data, the pixel pattern of the gray 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. 16th A
From the figure, control passes through the jump symbol 11 to the 1fIB diagram. The line data captured in step 578 is rlloOJ. Therefore, in step 580, the key line data N currently input using the cursor key is
The exclusive OR with 0OOJ r 0100J is taken, and this becomes the key line data at the new cursor position (582
), that is, an upward Ke line is formed.

Since such exclusive OR is performed, when the cursor is moved to a certain position on the line, the part of the line that matches the direction of movement of the cursor is erased. for example,
When the 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
The logical sum r 0OOOJ with 0J is taken, and the Kay line is erased. In this way, control $-584 and cursor key 5
By operating 88 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 590 indicates a cursor display.

In this embodiment, by adopting such a configuration of the line data, efficient processing of the line data is possible.As mentioned above, in this embodiment, there are three types of printing: normal printing, sequential printing, and mid-stop printing. There is. These can be selectively specified using specific keys on the keyboard IO. Regarding formats for printing and editing, paper size, line spacing, character spacing, vertical/horizontal writing, etc. can also be specified using specific keys. Regarding the paper size, A4 and B5 can be selected. Regarding the character spacing, the 1 inch gap between the dot formation areas of two adjacent characters can be selected from three types, for example, 0.28 mm, 0.58 layers, and 1.41 layers, and the line spacing For example, the gap between the dot forming regions of two adjacent rows is 0.
．． 85 layers m, 2.98111+, and 5.08mm
It is possible to select from three types.

Such format conditions are input for printing formats under the control of the format creation section 41B of the print control section 20, and for editing formats under the control of the editing section 18 and the left and right end display control section 316 of the display control section 2B. The mode can be changed. When changing the print mode, regardless of the print type, data regarding the selected line spacing, one-character spacing, and vertical/horizontal writing are set for print wi.

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 one edit.

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

FIG. 18 conceptually shows an outline of the format change operation performed by the editing section IB 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
For now, 0 is stored in the code data storage area 21B.
When normal printing is selected, the editing section 1B and the format creation section 41G import these setting data and set the format data for both printing and editing including print type, paper size,
You can change line spacing, character spacing, and vertical/horizontal writing. The editing unit 1B re-edits the text and layout according to the changed data.
The format creation unit 416 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 function to match. 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 feed φ line return is also calculated using the line spacing set for printing as a unit, and feeding is possible in the forward direction and the reverse direction. The movement of the print head and the line feed/backward movement are controlled by the head movement control section 402 and paper feed control unit 104, respectively, in accordance with the operation of specific keys on the keyboard 10.

More specifically, as conceptually shown in FIG. 19, the cursor skip is performed using the character spacing data B00 set for printing stored in the code data storage area 21B. The current print head digit position is calculated from the current print head and dot position data 602 from the head transfer control flA 402.
(11104), as can be seen from FIG. 17, in this embodiment, the cursor 59G 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 (808).
, the updated cursor position data is displayed in the cursor display area 5.
Supply to 0B. 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 800 set for printing stored in the code data storage area 218 and cursor display control. The dot position to which the print head is to be moved is calculated from the current cursor position data 81G from the section 312 (812). The head dot position is also calculated based on the number of dots in the half-width character width.

I [The head transfer control unit 40
2 calculates the amount by which the print head should be transported 810. In response to this, the head moving section 616 is controlled 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 802 is updated to the current position in the head position data storage area. FIG. 22 shows a specific operational flow of such head skip processing.

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

Referring to FIG. 23, the head transfer control performed by the head transfer control unit 402 is conceptually shown. Directional movement is instructed, and by simultaneous operation of control key 584 and non-conversion key 822, leftward movement of the print head is instructed. In response to this, the head movement control unit 402 calculates the head movement amount from the printing character spacing data 800 and the full-width/half-width mode information 824 (628).

The head movement amount is the sum of the number of full-width character dots and the character spacing for printing, but if the full-width and half-width mode information is set as "0" for full-width and rlJ for half-width, a single logical formula, (full-width Character spacing for printing dozens of character dots) / (Full/half-width mode information +
Calculated by 1).

The number of moving dots and the moving direction calculated in this way are given to the head transfer unit BlB, thereby printing f1122
The print head moves. Therefore, when the full-width mode is specified, the print head moves in full-width character width units, and when the 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 584 and paper feed key 632. In response to this, the paper feed control m 404 calculates a paper feed (return) amount from the printing line spacing data 630 (834), and the calculated paper feed (return) amount and paper feed (return) direction are Feed (return) section 8
38, and the printing section 22 is fed accordingly. Therefore, the recording paper is fed (returned) in the designated direction by an amount corresponding to the set printing line spacing. FIG. 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 IO is operated, mid-stop printing is started, printing starts from the character at the current cursor position to the character immediately before the print stop character, and then the printing operation is stopped and the characters are pressed by pressing the key. It will be possible to do it manually. If there is no print stop character, the end of the page will be printed,
A similar situation will occur. The print stop character is input using a specific key, and a specific mark such as "S" surrounded by a hexagon is displayed on the 1 display section 24. Print stop characters are not printed.

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

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

The line format, that is, the left and right edge information for printing of that line is created using the current head position data 850 and the left and right edge data 844 (84B). According to this line format, a print stop character is generated from the current cursor position, that is, the expansion start character address. The included text data 840 is expanded into text (642).

The expanded text data is processed by the print processing unit 85B that stops midway.
given to. Here, if the print type 648 specifies mid-stop printing, the print stop character is replaced with a full-width space, and the expanded data is sequentially supplied to the print data output unit 680.

The text expansion 842 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 851m. On the other hand, the line data development section 854 is given the line data 852 and the left and right edge information for printing, and forms line data from the development start character to the digit position including the print stop character. The line data correction unit 858 supplies the line data up to just before the printing stop character to the print data output unit 880. In this way, the print data output unit 660 sequentially outputs the characters of the text developed in the mid-stop print processing unit 85B to the printing unit 22, and when the print stop character is reached, outputs a print stop command. The system is now 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. To explain this in an easy-to-understand manner, as shown in Figure 29, up to 4
In the 0th line printing area 670, the 20th line print text is enlarged 10 times vertically and horizontally using lines 20 to 29, and the text on the 10th line 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 indicates that the maximum number of lines "40" set as format information is imported, and the enlargement information of each line is imported as enlargement information data. In this case, the 20th line is specified to be enlarged by 10 times in the vertical and horizontal directions. Data is captured. The operator uses the keyboard 10 to move the cursor to
If you place the text on line 0 and give an instruction to request the text to be enlarged 15 times vertically and 10 times horizontally, these data, the current cursor line number rlOJ, the requested vertical enlargement magnification "15", and The requested horizontal enlargement factor "10" is imported.

Therefore, the enlargement processing unit 430 calculates the maximum magnification of vertical enlargement that can be set from the format information, enlargement information data, and current cursor line number (872). Find the number of rows that do not. In this example, since the 20th line is set to be enlarged 10 times vertically and horizontally, the 20th to 23rd lines are consumed as enlarged lines.

Therefore, the remaining non-expanding rows are 11 from the 30th to the 40th row.
It is a row. 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 horizontal expansion magnification is corrected to the requested horizontal expansion magnification "12" (874).
10'' is used (87B), and this is registered in the expanded information table 880 together with the page number and line number (878).
Based on this table 680 shown in the figure, the printing data creation unit 424 creates printing data by modifying the pattern data in the character pattern development area 422 and the C line pattern development area 418, and enlarges it in the printing unit 22. The pattern data is output and enlarged printing is performed. The specific operation flow of such enlarged printing processing is shown in Figure 32A ~ @
Shown in Figure 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 highlighted, can be set by using the up cursor movement key or the down cursor movement key. Operating the up cursor movement key increases the magnification, and operating the down cursor movement key decreases the magnification. Enlargement processing is executed by operating the line feed key.

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

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

General characters that can be used in these input modes are registered in the conversion dictionary 104 of the editing section 1B.

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

The created external characters are displayed together with candidate numbers on the guidance screen 502, as in the case of single kanji conversion, and by selecting number 1, the document text can be converted.

That is, it can be input to the editing screen 500. In the example shown in Fig. 35, two external characters have already been registered in numbers "1" and "2".
can be registered. Also, the external characters registered in the document floppy 28 are read into the storage section 18 and used.

The creation process of external characters is mainly performed by the input control section 12 and the display control section 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 will be seen from now on, when a specific key on the keyboard 10 is operated, the already registered external characters are displayed on the 0 display section 22, which moves on to the external character pattern creation work, as shown in FIG. 35, for example. Therefore, if you want to create a new one, select "3" to "8" using the numeric keys. If modifying a registered pattern, select rlJ or "2".

Select a custom character copy by operating a specific key (special character key). An example of the operation flow for copying external characters is shown in FIG.
For example, in the example shown in Figure 35, if you operate the number key "3",
In response to this operation, first, the information 61 of the current cursor digit position is
0 is taken in, and the address of the character in the current cursor digit is obtained by referring to the digit correspondence address table 532 (ea
o) Search the text data 84G based on the obtained address information to obtain the code of the character corresponding to the address (1392), read the font pattern from the character pattern generation unit 522 using this code data,
This is stored together with the registration number in the third place in the external character pattern storage area 88B (894). When the number key "2" is pressed, the external character of the registration number "2" is changed. The capacity is 63 characters.

The layout display control unit 332 of the display control unit 26 reads out the pattern information in the external character pattern storage area 83B to 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 in the vertical and horizontal directions, and one pixel in a single character font is represented by a rectangle of 2 dots in the vertical and horizontal directions. As shown in FIG. 36, the cursor 898 is at 1 on the layout screen 504.
It is displayed by blinking the lower two dots (hatched portion in the figure) of the four pixel dots. This cursor 688 can also be moved using the cursor key 566 on the keyboard IO. By operating a specific key on the keyboard IO, one pixel at the position of the cursor 888 can be made black or white. When this specific key is pressed, the pixel indicated by the cursor 898 changes to black if it is a white pixel, and changes to white if it is a black pixel. FIG. 37 shows a state in which 0 has been 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 with a simple operation.

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

In the menu display shown in Figure 38, press the numeric key "2"
When the button is pressed, a display as shown in FIG. 33 is displayed, and the document can be registered in the floppy disk 2B.

In this embodiment, data is recorded on the floppy disk 28 in a format as shown in FIG. That is, the header section 700, the ledger section 702, the document area 7G4, and the external character section 70G. The header section 700 records the IO, the maximum number of documents that can be registered, and the number of registered documents.The ledger section 702 records the document name written in a maximum of 10 characters, paper size, line spacing, 1 character spacing, 2 vertical lines. The 0 document area 704 where format data such as fist horizontal writing format is saved includes the left end,
Information such as right edge, enlargement, and lines, and up to 20 texts
Recorded in 0 documents. The external character section can accommodate up to 84 external characters.

Returning to FIG. 33, as shown in the guidance area 502, if you operate either the cursor up or down keys in this state, the display of document numbers, that is, the identification display, shifts forward or backward one by one accordingly. In the embodiment, only document numbers without document names are picked up in the new registration mode, and only document numbers with document names are picked up in the registered update registration mode, and rotated and displayed in response to the cursor up and down keys. In the registered update registration mode, when the document shifts to the 200th document in the registered capacity, if the down shift key is further operated, the display returns to the first document and then returns to displaying the document name of the first registered document number. Similarly, when you have shifted to the first document, if you press the up shift key again, you will go back to the 200th document and then the document name of the last registered document number will be rotated and displayed.

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

Display the desired document number and press a specific key, such as the line feed key, to enter the document name using the character keys.0After entering the document name, or using the already called document name After using or modifying the document, if you press the new line key again, you can register the document. 0 You cannot register the document without even a single character being entered as the document name. If the document is recalled from the floppy 28, the document name is displayed first during registration.

Such document registration control is mainly performed by the external storage control section 3.
It is done by G. The situation is conceptually shown in Figure 41. First, edit! Obtain the document number and document name from the document information 710 being edited in 1518, and determine the document operation mode based on this (712) 0 If the first bit of the document name data is "0", the new registration mode is selected, or the document name If the code exists, the mode is for updating registered documents.

A document ledger is read into the storage part 18 from the ledger part 702 of the floppy 28, and from this ledger 702, the document name search part 714 searches for cursor up and down keys 720 and 722 (717°, 718
) Find the document number. At this time, in the new registration mode, only document numbers with the leading data of the document name "0" are picked up, and in the registered update registration mode, only document numbers with document names are picked up.

The document number and document name picked up in this way are
It is converted into the corresponding character font pattern and displayed in the display section 24.
will be displayed. A specific operational flow of the document name search process in such document registration is shown in FIGS. 42A to 42B.

When calling up a document registered in the floppy disk 28, the menu shown in FIG. 38 is displayed by operating the numeric key rlJ. As in the case of registration, by operating the cursor up and down keys 720 or 722 to rotate and display the desired document name, and operating the line return key with the desired document name displayed, the registered document can be recalled. .

According to this embodiment, the document registration area in the external storage device is distinguished between registered documents and unregistered documents, and only the unregistered area is displayed in the new registration mode, and the registered area is displayed in the registered document update mode. Display only. This display is
The cursor is rotated by operating the cursor up and down keys 720 and 722. By limiting the selection range of registration operations in this way, it is possible to avoid operational errors such as accidentally deleting registered documents or rewriting them with other documents.
