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, inputting a document, such as a Japanese word processor,
A document editing device with functions such as editing and printing, especially with a dot matrix type character generator,
In a document editing device equipped with the function of displaying characters composed of dot matrix stored in this character generator, various layouts including document layout display can be performed using reduced characters obtained by reducing and converting the characters. The present invention relates to the 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 It is roughly classified into a printing unit that prints a completed document and a control unit that includes a computer that controls each of the above units. The functions are roughly classified into inputting a document, editing the input document, saving the completed document, and printing.

[0003]

Of these, the functions relating to the operability of the document editing apparatus are mainly the document input function and the input document editing function among the above-mentioned functions, and are excellent in operability. The conditions of the document editing device are the following three points.

(1) The document display on the CRT monitor can be changed in a short time in response to document input and editing operations.

(2) The layout (hereinafter referred to as the layout) of one page of the created document can be easily confirmed.

(3) The contents of the document can be read on the layout display screen, and related to (2) above, when the character spacing and line spacing are changed by changing the format, they are accompanied by Layout display should always be possible using reduced character patterns that reflect the character spacing and line spacing in the document image when printing.

However, the first condition is that the shorter the time required to input a document is, the more preferable it is. As the operator becomes accustomed to the operation of the document editing apparatus,
There is a device that can input characters at a high speed of 00 to 200 characters / minute, and the operator confirms whether the characters input by him or the editing operation are correct by the characters displayed on the CRT monitor. Considering
To further improve the operability of the document editing device,
It is desirable to have this first condition.

The second condition is that it is desirable to have an image of the document layout when the created document is edited or rearranged (in other words, when the document is input or edited by the conventional document editing apparatus). The display is 10 to 20 lines,
Since only a part of one page of a document having about 40 lines is displayed, and the display does not change even when the character spacing or line spacing during editing is changed, the document editing apparatus Considering that it is difficult to imagine the layout of the document from the display screen being edited, it is desirable to have the second condition).

Among the third 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 a conventional document editing apparatus adopting the code refresh method. Consider the case where the layout of a document is displayed by simply replacing characters on the screen with alternative symbols that are far apart from the actual characters such as asterisks or stars (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 third front stage in order to further improve the operability of the document editing apparatus.

Unlike the above, a technique for displaying a layout using a reduced character pattern has also been previously proposed, but conventionally, the character spacing and line spacing of the reduced character pattern on the layout display screen are It is always fixed, and therefore, when editing the document, even if the character spacing and line spacing are changed by changing the format, the reduced character pattern on the layout display screen does not change, and as a result, the printed matter printed after the editing is completed. If the layout of the document does not suit the creator of the document, it is forced to re-edit it, resulting in a problem that the work becomes complicated. In the conventional case, the overall layout for one page of the document is roughly rough. Even if you understand
It is hard to say that it is a print image display in the true sense.

From the above, when the character spacing and line spacing are changed by changing the format, that is, the latter condition of the third conditions, the document image at the time of printing is always accompanied by this. It is also desirable to provide a means for performing layout display using a reduced character pattern that reflects character spacing and line spacing in order to further improve the operability of the document editing apparatus.

However, no existing document editing apparatus satisfies all the above three conditions.

According to the present invention, the document display can be changed in a short time, the layout can be easily confirmed, and the content of the document can be read on the layout display screen. The layout can be always displayed using a reduced character pattern that reflects the character spacing and line spacing in the document image at the time of printing, and as a result, the layout of the printed matter printed after the editing is completed is in line with the creator of the document. Eliminates the complexity of re-editing due to lack of
It is an object of the present invention to provide an easy-to-use document editing device.

[0014]

SUMMARY OF THE INVENTION The above-mentioned object is to provide a text editing device including a dot matrix character generator, a document data storage means, a document data changing means, and a monitor, and If you change the character spacing and line spacing by changing the format and the first edit mode that performs editing while displaying
A second edit mode for displaying a layout using a reduced character pattern based on the character spacing and line spacing in a document image at the time of printing based on the document data; and the first edit mode and the second edit during editing. And edit mode changing means for changing the mode.

[0015]

The greatest feature of the present invention having the above construction is that when the character spacing and line spacing are changed by changing the format, the reduced character always reflects the character spacing and line spacing in the document image at the time of printing. This is because the layout is displayed using a pattern, and as a result, the complexity of re-editing due to the layout of the printed matter printed out after the editing is not intended by the document creator can be eliminated.

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 as 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 the 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 creation program or the document editing program is processed by the code refresh memory 31 in accordance with the input processing or editing processing program having the flow shown in FIG. 4 or 5 in the program memory 303.
CRT12 by code refresh method using 0
3 is displayed above.

A command for processing associated with inputting and 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, and erases the code refresh type document display by the input processing or editing processing program shown in FIGS. 5 and 5 from the CRT 123.

Next, 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, the display position of the character at the time of layout display is calculated by the CPU 301, and then based on the display position information and the character code, FIG. A reduced character pattern is written in the dot refresh memory 311 by the reduced character writing program having the flow as described above.

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

When the layout display for one page by the reduced characters is completed, it is selected whether or not the edit processing is performed on the layout display screen, and when the edit processing is performed, the same as the edit processing on the document display screen by the code refresh method is performed. An instruction for editing processing is input from the keyboard 122 to update the inside of the document buffer.

As shown in FIG. 8, the program flow of the editing process is such that the command input from the keyboard 122 is used for editing the character deletion, moving, changing the format, and changing the layout of the document. , Which is to be judged, and each of the processes described below is performed. When none of them is met, the process returns to the instruction input of the edited contents and has a new instruction.

In the case of character deletion, by instructing the deletion range from the keyboard 122, the CPU 301 deletes the corresponding character code in the document buffer according to the program and replaces the new character code.

In the case of correction, by inputting the character to be corrected by instructing the correction range from the keyboard 122, C
The PU 301 replaces the corresponding character code in the document buffer with a new character code according to the program, and newly replaces the character code in the document buffer.

In the case of movement, by instructing the movement character string range and movement destination from the keyboard 122, the CPU 30
1 moves the character code in the document buffer according to the program, and newly replaces the character code.

In the case of changing the format, the CPU 301 rewrites the format information in the document buffer according to the program by instructing a new format from the keyboard 122.

In the case of changing the layout such as setting a frame and setting an input prohibited area, when an instruction for a new layout is input from the keyboard 122, the CPU 301 displays the frame opening information of the document buffer and the display prohibited area information according to the program. rewrite.

As described above, the character code in the document buffer is rewritten with new document information.

When the editing process is completed in this way, the process returns to the character display start point of the layout display program as shown in the flow of FIG. 6, and the layout after the editing process is repeated by repeating the layout display process.
23 to display.

When the editing process is completed or when the editing process is not performed, the layout display is continued until the layout display is completed, and the CP display is instructed by the layout display end instruction.
U301 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 shown in FIG. 6 is performed by executing the reduced character writing program having the flow 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), the reduced character pattern is reduced to m × n character pattern D ′, and the reduced character pattern is converted into dots. This is a process for writing to a corresponding position in the refresh memory 311.

Conventionally, as a method of 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.

In the former case, however, the character pattern may change and the character may not be discriminated. In the latter case, the reduction process is performed once in 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 by 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 of the characters such as hiragana, katakana, numbers, etc., in which the hatched area in the 24 × 24 dot pattern of FIG.
Even after reduction conversion, it is readable with only one character, and it is difficult to distinguish semi-voiced characters such as "po" and "vo" from 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.

In addition, 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 by the reduced characters that have undergone the reduction conversion, the document displayed on the layout display screen can be read and the layout of the document according to the contents of the document can be arranged. It becomes possible to confirm. Further, since the contents of the document can be read on the layout display screen, in the case of the illustrated embodiment, the editing process such as correction, insertion, movement, etc. of the document can be performed by the program having the flow shown in FIGS. It can also be done on the layout display screen.

As described above, according to the present embodiment, by providing the code refresh memory and the dot refresh memory in the document editing apparatus, the code refresh method excellent in high-speed response as the display method and the dot refresh method having a high degree of freedom in display are provided. Can be selected at any time by switching as required.

Thus, at the time of inputting or editing a document which requires high-speed response of display, by using the code refresh method excellent in high-speed response, the conditions of the document editing apparatus excellent in operability described above are satisfied. Even when the character spacing and line spacing are changed by changing the format, the dot refresh method, which satisfies the first condition and has a high degree of freedom in display, is used when displaying a layout that requires a high degree of freedom in display. The layout can be displayed using a reduced character pattern that reflects the character spacing and line spacing in the document image at the time of printing, and as a result, the layout of the printed material printed after editing is not suitable for the document creator. Among the conditions of the document editing apparatus having excellent operability, the second and third conditions can be eliminated, such as the complexity of re-editing caused by the above. It is possible to satisfy the matter.

Conventionally, the character spacing and line spacing of the reduced character pattern on the layout display screen are always fixed. Therefore, when the character spacing and line spacing are changed by changing the format when editing the document, the layout display The reduced character pattern on the screen does not change, and as a result, if the layout of the printed matter that is printed out after editing is not suitable for the creator of the document, re-editing is forced and the work becomes complicated. That point has already been mentioned.

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 apparatus is lower than that of the document editing apparatus having the separate character generator dedicated to the reduced characters. 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 2 lines reduced and 4 dots logical sum in reduced character writing. 1 dot conversion by
Storage of reduced character as one line of information, and reduced character 1
A conversion device such as an LSI, which is configured by hardware such as writing lines to the 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, so the time required to complete the layout display at the time of layout display is short. There is an effect that.

Further, in the above-mentioned embodiment, the dot refresh memory is provided for the layout display by the generated reduced character pattern, but this dot refresh memory is stored in the CG. , Is used for layout display 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. It can be configured.

[0060]

The present invention is as described above, and as is apparent from the description of the illustrated embodiment, according to the present invention, (1) a document is input and edited on a monitor in a short time. You can change the display.

(2) The layout (layout) of the entire page of the created document can be easily confirmed.

(3) In addition to the fact that the contents of the document can be read on the layout display screen, when the character spacing and line spacing are changed by changing the format, the character spacing and line spacing in the document image at the time of printing are always maintained. The layout can be displayed using the reduced character pattern that has been reflected, and as a result, the complexity of re-editing due to the layout of the printed matter printed out after the editing is not intended by the creator of the document is eliminated. An easy-to-use document editing device can be obtained.
