Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing device,
For example, in a document editing device having functions such as inputting, editing, and printing of a document such as a Japanese word processor, various layouts including a layout display of a document can be performed by using reduced characters obtained by reducing and converting the characters. The present invention relates to a document editing device.

[0002]

2. Description of the Related Art Generally, a document editing apparatus as described above is
Input unit for inputting characters, symbols, etc., display unit for displaying characters, symbols and documents created / edited by the input unit, temporary storage unit for storing information such as control programs and prepared documents, on paper The document is roughly classified into a printing unit that prints a completed document and a control unit that includes a computer that controls each unit. The functions are roughly classified into inputting a document, editing the input document, and saving and printing the completed document.

[0003]

Among these functions, among the above-mentioned functions, the functions relating to the operability of the document editing apparatus are mainly the document input function and the input document editing function, and the document having the excellent operability. The following conditions can be mentioned as conditions for the editing device.

(1) The layout (hereinafter referred to as the layout) of one page of the created document can be easily confirmed by the document image at the time of printing.

(2) As related to the above (1), the contents of the document can be read on the layout display screen, and the layout display screen can be displayed on the layout display screen without frequent switching. Be able to edit.

That is, it is desirable that the above-mentioned first condition has an image of the layout at the time of printing the document when the created document is edited or rearranged (in other words, in the conventional document editing apparatus). The display when inputting and editing a document is 10 to 20 lines, and only a part of one page of a document, which is about 40 lines, is displayed, and the display also shows line spacing and character spacing. Considering that it is difficult to imagine the layout of the document from the display screen of the conventional document editing apparatus, since it does not change even if the format is changed, it is desirable to have this first condition).

Among the second conditions, the first condition, that is, the condition that the contents of the document can be read on the layout display screen, is displayed as in the layout display as is performed by the conventional document editing apparatus employing the code refresh method. Consider the case where the layout of a document is displayed by simply replacing the characters on the screen with an alternative symbol such as an asterisk or an asterisk, which is far from the actual characters (in other words,
When editing a document in consideration of the layout, the layout display screen and the normal display screen where the document can be edited must be frequently switched in order to confirm the layout, confirm the contents of the document, and perform the editing work. However, considering that the operation is very complicated), it is also desirable to provide the condition of the second front stage in order to further improve the operability of the document editing apparatus.

Unlike the above, a technique for performing layout display using reduced character patterns has also been previously proposed, but conventionally, the line spacing and the character spacing of the reduced character patterns on the layout display screen are always fixed. Therefore, when editing a document, the reduced character pattern on the layout display screen does not change even if the line spacing and the character spacing are changed by changing the format in the normal screen display state which is the standard character display screen. If the layout of the printed material printed out after finishing is not suitable for the creator of the document, it will be forced to re-edit and the work will be complicated. Even if you can understand it, it is hard to say that it is a true print image display.

In addition to this, if the second condition of the second condition, that is, the latter condition, that is, if the editing process can be performed on the layout display screen without frequently switching between the layout display screen and the normal display screen, The operability of the document editing device is further improved.

The present invention enables easy confirmation of the layout of a document image at the time of printing and interpretation of the document content on the layout display screen. In particular, the frame of the positional relationship corresponding to the content (text) of the document, It is possible to change the setting of the input prohibited area even on the layout display screen, and it has excellent operability, and the complexity of re-editing due to the fact that the layout of the printed matter printed out after editing is not suitable for the document creator To provide an easy-to-use document editing device
That is the purpose.

[0011]

Means for Solving the Problems The above-mentioned objects are: a document pattern generator, a display device, a document buffer, a document buffer storage content changing means, a standard character display screen editing means, and a document buffer storage. A layout display means for calculating a character display position according to the content and displaying the layout using a reduced character pattern representing a document image at the time of printing; Or) It is achieved by having a layout changing means for rewriting the input prohibited area information.

[0012]

According to the present invention having the above-described structure, the layout display means for displaying the layout by using the reduced character pattern representing the document image at the time of printing is provided, and the frame of the document buffer is further displayed while the layout is displayed on the screen. It has a layout changing means for rewriting the opening information and / or the input prohibited area information, and allows easy confirmation of the layout in the document image at the time of printing and reading of the document contents on the layout display screen. It is possible to open the frame of the positional relationship corresponding to the content (text) and change the setting of the input prohibited area on the layout display screen.

A CRT 123 related to a display unit and an FDD 125 related to a temporary storage unit are installed on the front surface of the main body 121.

The overall operation of the document editing apparatus having the above structure will be described below.

That is, in the above configuration, when the power is turned on, a program stored in a flexible disk in the FDD 125 and operated as a document editing apparatus having the flow shown in FIG. 3 according to the program in the boot ROM 302. The program memory 303
Then, the operation as the document editing apparatus is started in accordance with the program having the flow shown in FIG.

In FIG. 3, the auxiliary function means, for example, that the user separately designs the character shape,
This shows a process for inputting this.

When the input process or the edit process is selected from among the respective processes by the work selection input, the document creation program or the document edit program having the flow shown in FIG. 4 or 5 is executed. The document being created or edited by the document creating program or the document editing program is processed by the code refresh memory 31 according to the input processing or editing processing program in the program memory 303 having the flow shown in FIG. 4 or 5.
CRT12 by the code refresh method using 0
3 is displayed above.

A command for processing associated with inputting or editing characters in the document is input from the keyboard 122 and detected by the CPU 301 via the key input controller 308.
In accordance with the input, the CPU 301 writes the character code of the input character in the code refresh memory 310 and displays the input character on the CRT 123, or displays the character code in the code refresh memory 310 according to the instructed editing process. Change the display document on the CRT 123. At this time, the CPU 301 also changes the document information in a portion (called a document buffer) in the program memory 303 where the document information is stored.

When a layout display command is input from the keyboard 122, the CPU 301 detects execution of layout display via the key input controller 308,
The CPU 301 executes the layout display program stored in the program memory 303 and having the flow as shown in FIG.

When the layout display process is started, the CP
The U 301 gives a command to the CRT controller 305 to erase the code refresh type document display by the input processing or editing processing program shown in FIGS. 5 and 6 from the CRT 123.

After the dot refresh memory 311 is initialized and this process is completed, a command is given to the CRT controller 305 to display the content of the dot refresh memory 311 on the CRT 123, and the content of the dot refresh memory 311 is displayed on the CRT 123. To be displayed in.

Next, the character code is sequentially read from the document buffer in the program memory 303 by the "character code reading" process in FIG. 6, and the display position of the character at the time of layout display is calculated by the CPU 301 by the "display position calculation" process. After that, based on the display position information and the character code, the "reduced character writing" process having the flow shown in FIG. 7 is used to perform a position corresponding to the display position of the character when the layout of the dot refresh memory 311 is displayed. The reduced character pattern corresponding to the character code is written in.

By repeating this processing until the layout display for one page is completed, the layout of the document with reduced characters is displayed on the CRT 123.

When the layout display for one page by the reduced characters is completed, either the edit processing is selected on the layout display screen by the "edit?" Processing in FIG. 6, and when the edit processing is performed, the code refresh method is used. In the same manner as the editing process on the normal document display screen by the command input command of editing process such as character deletion correction, movement, format change, layout change, etc. from the keyboard 122, the data in the document buffer is changed to the data changed by the process. To update.

As shown in FIG. 8, the flow of the editing process program at the time of displaying the layout is as follows. The commands input from the keyboard 122 are character deletion correction, move, format change, and document layout change in the editing process. of,
Which of the following is to be performed and each of the processes described below is to be performed. If none of them is met, the process returns to the instruction input of the edited contents and waits for a new instruction.

In the case of character deletion, by instructing the deletion range from the keyboard 122 in the "deletion range designation" process in FIG. 8, the CPU 301 follows the program and executes the "document buffer update" process in the character information in the document buffer. Delete the corresponding character code and replace it with a new one.

In the case of correction, the CPU 30 is operated by instructing the correction range from the keyboard 122 by the "correction range designation character input" process in FIG. 8 and inputting the character to be corrected.
According to the program, 1 is a "document buffer update" process, in which the corresponding character code in the character code information in the document buffer is replaced with a new character code, and the character code in the character code information in the document buffer is newly replaced.

In the case of movement, the CPU 301 executes a "document buffer update" process in accordance with a program by instructing the range of the move character string and the move destination from the keyboard 122 in the "move character string instruction, move destination instruction" process in FIG. With, the character code is moved within the character code information in the document buffer and the character code is newly changed.

In the case of a format change such as line spacing or character spacing change, the keyboard 122 is selected by the "new format input" process in FIG.
By instructing a new format such as a newer line spacing or character spacing, the CPU 301 rewrites the format information in the document buffer with the new format information by the "document buffer update" process according to the program.

In the case of changing the layout of the document such as setting the frame of the document or setting the input prohibited area, when the instruction for the new layout is input from the keyboard 122 by the "new layout instruction" process in FIG. 8, the CPU 301 follows the program. In the "document buffer update" process, the frame opening information and the display prohibited area information in the document buffer are rewritten with new information.

As described above, the character code information, the format information, the frame opening information and the display prohibited area information in the document buffer are rewritten with new document information.

When the editing process at the time of the layout display is completed in this way, the process returns to the point before the "character code reading" process, that is, the point of starting the character display of the layout display program, as shown in the flow of FIG. Program memory 3 by "Character code reading" process
The character code is sequentially read from the document buffer in 03,
After the CPU 301 calculates the display position of the character in the layout display by the "display position calculation" process, the "reduced character writing" process having the flow shown in FIG. 7 based on the display position information and the character code. By repeating the layout display process of writing the reduced character pattern corresponding to the character code to the position corresponding to the display position of the character in the layout display of the dot refresh memory 311, the reduced character of the document after the editing process is repeated. The layout according to is displayed on the CRT 123.

That is, as shown in the flow charts of FIGS. 6 and 8, since the layout display processing is performed again after the editing processing is performed, when the editing processing is performed on the character string such as character deletion, correction, or movement. , The layout of the reduced characters of the document changed to the edited character string was redisplayed, and the format was changed to change the document format such as line spacing and character spacing related to the character string density of the document. In this case, the layout of the reduced characters of the document that has been changed to the line spacing and character spacing after the format change process is displayed again, and the layout of the document such as the setting of the document frame and the input prohibited area is changed. Also in this case, the layout by the reduced characters of the changed document is redisplayed in the frame opening after the layout change process or the input prohibited area.

When the editing process is completed or when the editing process is not executed, the layout display is continued until the layout display is completed, and the CP display is instructed by the layout display end instruction.
The U 301 instructs the CRT controller 305 to stop the display by the dot refresh method and display by the code refresh method, and returns to the document creation or document editing program.

Before and after, the display of characters on the CRT 123 in the layout display program having the flow as shown in FIG. 6 is performed by executing the reduced character writing program having the flow as shown in FIG.

As shown in FIG. 9, the reduced character writing program generally has km, k, j, m, and n as constants, and km ×
Character pattern D represented by a dot matrix of jn
D '(x, y) = D (kx, jy) + D (kx +
1, jy) + ... + D [k (x + 1) -1, jy] + D
(Kx, jy + 1) ... + D [k (x + 1) -1, jy
+1] ... + D [kx, j (y + 1) -1] + ... + D
According to the algorithm represented by [k (x + 1) -1, j (y + 1) -1] (where, + represents a logical sum),
A process of reducing the size to the m × n character pattern D ′ and writing the reduced character pattern at a corresponding position in the dot refresh memory 311 is performed.

Conventionally, as a method for obtaining a character pattern in which a character pattern represented by a dot matrix pattern of km × jn is reduced, a method of obtaining a reduced character pattern by thinning out appropriate rows and columns of the character pattern represented by a dot matrix. Alternatively, a logical reduction of two rows or two columns appropriate for one direction of the row or column is performed, and the newly obtained one row or one column is replaced with the above two rows or two columns to obtain a reduced pattern reduced in one direction. There is known a method of obtaining the final reduced character pattern by performing the two processes of obtaining and then reducing the remaining directions by the same method.

However, in the former case, the character pattern may change and the character may not be discriminated. In the latter case, the reduction process is performed once in each of the column and row directions to obtain the final reduced character pattern. Since it has to be performed twice, there is a drawback that the processing time is long.

The reduction method according to the above algorithm is shown in FIG.
As shown in, the processing time is reduced to half as compared with the conventional method because the final reduced character pattern can be obtained by one reduction process, which is a remarkable effect as the reduction method alone.

In the present embodiment, each constant in the conversion formula is j
= K = 2 and m = n = 12, the reduced character writing program having the flow shown in FIG. 7 is used to display a character pattern displayed on the CRT 123 as a matrix pattern of 24 × 24 dots as shown in FIG. 11 when displaying a document. Two
The character pattern is read line by line from the CG 304 and the character pattern is read as shown in FIG.
As shown in the example of No. 401 of “0” line and 402 of “1” line
2 dots vertically and horizontally, a total of 4 dots, according to the logical formula D ′.
(X, y) = D (2x, 2y) + D (2x + 1,2y)
+ D (2x, 2y + 1) + D (2x + 1,2y + 1)
(1) In accordance with (the hatched portion in FIGS. 10 to 12 is logical "1"), one dot is converted into one dot, thereby forming a reduced pattern for one line of 403 and writing it in the dot refresh memory 311. By repeating the above, 12 × 12 on the CRT 123 as shown in FIG.
Display reduced characters in a dot matrix pattern of dots.

By using the document editing apparatus having the above-described structure and operation, the characters can be displayed on the layout display screen with the conventional asterisks and star marks without preparing a dot matrix pattern of the characters for the layout display separately. It is possible to display it as a readable character such as that shown in FIG. 12 instead of the substitute symbol such as.

Of course, not all character patterns are legible even after being reduced and converted according to this embodiment. However, according to the experiment, almost all characters, such as hiragana, katakana, and numbers, which have a relatively small area of the shaded area in the 24 × 24 dot pattern of FIG. 11, can be read by only one character even after the reduction conversion. It is difficult to distinguish between semi-voiced characters such as "" and "bo" and voiced characters. However, the probability that these semi-voiced characters and voiced characters appear in the document is low, and even if they appear, they can be read according to the context of the document.

Also, a reduced character obtained by reducing and converting a Chinese character can be read with only one character as shown in FIG. Considering that the probability of Chinese characters appearing in a document is 40 to 50%, and considering the above, one of the characters in the document
It can be estimated that about 70 to 80% of the characters are legible only by the characters. Considering that characters that cannot be read with only one character appear in succession in the reduced document, and even if they do appear, almost all of them can be judged by the context. ,
It can be concluded that the document on the layout display screen according to this embodiment is legible.

Therefore, by displaying the layout of the document with the reduced characters reduced and converted, the document displayed on the layout display screen can be read, and the line spacing and the character spacing according to the content of the document can be read. It is possible to check the layout of the document such as a frame opening and an input prohibited area. Further, since the contents of the document can be read on the layout display screen, the program having the above-described flow of FIGS. 6 to 8 can be used to change the character strings of the document such as deleting, correcting, moving, etc. Change the document format such as line spacing and character spacing related to character string density,
It becomes possible to perform editing processing for changing the layout of the document such as opening the frame of the document and setting the input prohibited area on the layout display screen.

As described above, according to the present embodiment, since the document editing apparatus is provided with the code refresh memory and the dot refresh memory, the character input using the code refresh method excellent in high-speed response as the document display method,
It is possible to switch between the display at the time of editing and the layout display of the document using the dot refresh method, which has a high degree of freedom in display, and switch between them as needed to select them.

As a result, at the time of inputting or editing a document requiring high-speed responsiveness of display, the character input and the display at the time of editing using the code refresh method excellent in high-speed responsiveness are used, while the degree of freedom of display is increased. When the layout display is required, the dot refresh method having excellent display flexibility is used, and the display position of the reduced character pattern at the layout display is calculated as shown in the program of FIG. By writing the character code in the position, the layout display screen is changed by changing the line spacing and character spacing, opening the frame, and changing the setting of the input prohibited area, and the complete layout display is performed. Of the above, the first condition is satisfied, and by using the reduced character described above as the character used for the layout display, In addition to the fact that the contents of the document can be read on the layout display screen as described above, the layout display is performed again when the editing process is performed on the layout display screen as shown in the programs of FIGS. 6 to 8. The second of the conditions of the document editing apparatus described above
The document editing device satisfying the conditions of 1), and in particular, it is possible to open the frame of the positional relationship corresponding to the content (text) of the document and to change the setting of the input prohibited area on the layout display screen, which is excellent in operability. Will be able to provide.

Further, according to the present embodiment, since the character generator having the character pattern for layout display is not required, the price of the document editing device is lower than that of the document editing device having the character generator dedicated to the reduced character. It will be

In addition to the document editing apparatus according to the above-described embodiment, the reduced character display program shown in FIGS. 6 and 7, that is, at least two line reductions and four-dot logical sums in reduced character writing. 1 dot conversion by
Storage of reduced character as one line of information, and reduced character 1
A conversion element such as an LSI, which is configured by hardware such as writing in a row display memory, or a program for generating a dot matrix pattern of reduced characters related to the conversion in the flow of FIG. Although it is conceivable that the present invention is configured by hardware according to the above, it is clear that this is also included in the present invention.

If the above program is configured by hardware, the processing time is shorter than that of processing all by software as in the present embodiment, and therefore the time required to complete the layout display at the time of layout display is short. There is an effect that.

Further, in the embodiment described above, the dot refresh memory is used for layout display by the generated reduced character pattern, but this dot refresh memory is stored in the CG. , A layout provided by a separate pattern showing the existence of various character symbols, figures, or fixed things, and also by a pattern generated by the CPU using a calculation formula. Can be one.
