Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a document editing device, such as a Japanese word processor, which has functions such as document input, editing, printing, etc. The present invention relates to a document editing device having a function of displaying the layout of a document using characters.

[Background of the invention]

In general, a document editing device consists of an input section for inputting characters, symbols, etc., a display section for displaying the characters and symbols entered from the input section and documents created and edited, and a temporary storage section for storing information such as control programs and already created documents. It is roughly divided into a storage section, a printing section that prints a completed document on paper, and a control section that includes a computer that controls each of these sections. Its functions can be broadly divided into document input, editing of input documents, and saving and printing of completed documents.

By the way, it goes without saying that it is generally easier to edit or rearrange a created document while checking the layout and balance of the entire document.

Therefore, in conventional document editing devices, in order to check the layout and balance of the created document, a display device that displays the layout of the entire page of one document (hereinafter referred to as layout) is separate from the display device for displaying the document. There is something set up.

However, these devices require a display device for displaying the document and a display device for displaying Layer 1~, which makes the configuration of the display device complicated and expensive, and also makes it difficult to display documents and layouts. Since they are displayed at the same time, there is a drawback that editing processing such as correction and replacement of literary and ancient texts becomes slow.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to propose a document editing device that reduces character patterns for layout display format to an appropriate size by reducing normal document expression format patterns, and facilitates document editing during layout display. It is in.

[Summary of the invention]

In order to achieve the above object, the present invention includes: a document editing processing means; a display; displaying a document edited by the editing processing means on the display in a normal document display format; The display control means displays a character pattern in a layout display format of 8×8 dots or more in a normal document display. The format pattern is reduced to 1 bit, which is less than 1 bit I, and displayed.

At the front of the main body 121, a CRT 123 as a display section and an FDD 125 as a - time storage section are installed.

A detailed circuit diagram of the pattern conversion circuit 500 is shown in FIG. 501 to 503 are 8-bit registers that temporarily set conversion inputs; 504 is a quaternary counter that selects a register and provides a write signal; 505 is a bus driver that calls the result obtained in the 8-bit register 507 to the CPU;
506-a to 506-h are OR gates that perform a logical sum between each bit of data in the 8-bit registers 501 to 503.

507 is a register that stores the ORed result.

Now, when the power is turned on with the above configuration, this device executes a program stored in the flexible disk in the FDDI 25 that operates as a document editing device having the flow shown in FIG. 3 according to the program in the boot ROM 302. 303 and starts operating as a document editing device according to this program. Here, the auxiliary function is a general term for a function that aggregates functions such as copying a document on a flexible disk to another flexible disk.

When input processing or editing processing is selected by the work selection input, the input processing program or editing processing program having the flow shown in FIG. 4 or 5 is executed. The document being inputted or edited is displayed on the CRT 123 by the code refresh method using the code refresh memory 310 according to the input processing or editing processing program having the flow shown in FIG. 4 or 5 in the program memory 303. be done. Commands for processing associated with character input and editing of the document are issued using the keyboard 1.
22 and is detected by the CPU 301 via the key controller 308 .

According to the input, the CPU 301 writes the character code of the input character to the code refresh memory 310, and displays the input character on the CRT 123, or writes the character code of the input character to the code refresh memory 310 according to the commanded editing process.
The character code in 0 is changed and the displayed document on the CRT 123 is changed.

At this time, the CP'U 301 is a part of the program memory 303 in which document information is stored (referred to as a document buffer).
Also change the document information within.

By the way, approximately 8000 Chinese characters, symbols, etc. must be prepared in a document processing device, but half of them are old characters and the like, and are used infrequently. Frequently used kanji are always stored in the non-volatile memory of CG1 at 304, but less frequently used kanji and character patterns created by the user as needed are usually set to 125. The information is stored on a flexible disk, and when necessary for display, it is called up and used in the read/write memory of the CGI 304 at any time.

When a layout display command is input from the keyboard 122, the CPU 301
detects a layout display execution command, and the CPU 301 executes a layout display program having the flow shown in FIG. 6 stored in the program memory 303. When the layout display process starts, the CPU 301
A command is given to the RT controller 305 to erase from the CRT 123 the document display of the code refresh memory method by the input processing or editing processing programs shown in FIGS. Next, the dot refresh memory 311 is initialized, and the CPU 301
5, nothing is displayed on the CRT 123 even if display using the dot refresh memory method is instructed. After this process is completed, the dot refresh memory 311
commands the CRT controller 305 to display the contents on the CRT 123, and the contents of the driver 1-retrieval memory 311 are displayed on the CRT 123. Next, the character codes are sequentially read from the document buffer in the program memory 303, and the CPU 301 calculates the display position of the character when displaying the layout.
2, and if it exists, one character of the reduced character pattern is read from CG2 of 312 and written to the corresponding position in the dot refresh memory 311.

If the character code is not in CG2 of 312, that character has been read from the flexible disk into the readable/writable memory section of CG1 of 304 at any time, so the CPU
301 calls the character pattern, generates an 8×8 character pattern using the pattern converter 313, and writes it to the corresponding position in the refresh memory 311 in the same manner as described above.

This process is performed by the CPU 301 using a pattern converter.
This is done by executing a reduced character writing processing program having the flow shown in the figure. The reduced character writing processing program is
Using a 313 pattern converter, as shown in FIG.
(kx+1.j k)+-+D(k(x+1)-1,j
y)+D(kx,jy+1)+-+D[k(x+1)-
1,j y+1)+D[kx,j(y+1)-1]10-+D(k(x+1)-4,j(y+1)-1)(However,
+ indicates logical sum. ), the character pattern DR is reduced to mXn, and the reduced character pattern is written to the corresponding position in the dot refresh memory 311.

In this embodiment, each constant in the conversion formula is set to j = 3 m = n = 8, and the reduced character writing processing program having the flow shown in FIG. CRT
The character pattern displayed in a matrix pattern of 24×24 dots on 123 is read out three lines at a time from the character generator 304, and as shown in FIG. (In Figures 9 and 10, the shaded area is defined as logic "1".) Using the pattern converter 500, which has the function of converting into one dot according to Create a reduced pattern for one character, write it to the dot refresh memory 311, and write it to the CRT.
123, the reduced characters of the 8×8 dot matrix pattern shown in FIG. 12 are displayed.

This process is repeated until the layout display for one page is completed, and the layout with reduced characters is displayed on the CRT 123.

When the layout display for one page is completed, select whether to perform editing processing on the layout display screen, and when performing editing processing, use the keyboard 122 to perform editing processing in the same way as editing processing on the document display screen using the code refresh method. input the command to update the contents of the document buffer. The program flow for editing processing is as shown in Figure 8.
It is determined which of editing processing the command input from the keyboard 122 corresponds to, character deletion and correction, movement, and format change.The respective processing is performed. If none of the instructions apply, return to inputting instructions for the edited content and wait for new instructions.

In the case of character deletion, when a deletion range is specified from the keyboard 122, the CPU 3'01 deletes the corresponding character code in the document buffer and rearranges a new character code according to the program.

In the case of correction, when the correction range is specified from the keyboard 122 and the character to be corrected is input, the CPU 301 replaces the corresponding character code in the document buffer with a new character code according to the program, and rearranges the character codes in the document buffer. change.

In the case of movement, when the movement character string range and movement destination are specified from the keyboard 122, the CPU 301 moves the character code within the document buffer according to the program and rearranges the character code.

In the case of a format change, when a new format is specified from the keyboard 122, the CI) TJ 30 rewrites the format information in the document buffer according to the program.

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

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 flow returns to the point where the layout display program starts displaying characters as shown in the flowchart of FIG.
123.

When the editing process is finished or when no editing process is to be performed, continue displaying the layout until instructed to end the layout display.
When the layout display ends, the CPU 301 instructs the CRT controller 305 to stop displaying using the dot refresh method and displaying using the code refresh method, and returns to the input processing or editing processing program.

If you use a document editing device that has the structure and operation described above, you can change the characters on the layout display screen to conventional "*" or "★" characters.
Instead of an alternative symbol such as , it can be displayed as readable characters as shown in FIG.

Of course, all 24x24 dot character patterns are
Even after reduction to 8×8 dots, it is still not legible. However, according to experiments, almost all of the characters such as hiragana, katakana, and numbers, which have a relatively small area of the diagonal line in the 24 x 24 dot pattern in Figure 11, can be read with just one character even after reduction conversion. It is difficult to distinguish between semi-voiced characters such as ``bo'' and ``bo'' and diacritic characters. However, the probability that these half-voiced on characters or akuon characters will appear in a document is low, and even if they do appear, they can be read depending on the context of the document.

Furthermore, 20% to 30% of the frequently used kanji characters can be read with only one character, as shown in FIG. The probability that a kanji appears in a document is 30
~40% and considering the above, the number of characters that can be read even just one character in a document is 60 to 7.
It can be estimated that it is around 0%. Considering that it is rare for a single character to appear consecutively in a document after reduction conversion, and even if it does appear, almost all of them can be read depending on the context. Layout I according to the Example - It can be concluded that the document on the display screen is legible.

Therefore, by displaying the layerers 1 to 1 of the document using reduced characters, the document displayed on the layout display screen becomes readable, and the character arrangement can be confirmed in accordance with the content of the document. Also, since the content of the document is readable on the Layout I display screen, the document can be corrected and inserted using a program having the flow shown in FIGS. 6, 7, and 8 described above.

Editing processing such as movement can be performed on the layout display screen.

Further, the layout display processing time is significantly reduced because the generation of the reduced character pattern as shown in FIG. 12 is processed by the circuit shown in FIG. 13.

As described above, the document editing device of the present invention can shorten the time required to complete layout display using reduced characters, and can be put to practical use.

Furthermore, if the reduced character pattern for displaying the layout is an 8 x 8 dot pattern as in this example, JIS 1
Character patterns of 3,418 characters and 256-bit masks can be stored in one ROM, and the board area occupied by the character generator that stores character patterns for layout display is small, and can be added to the control circuit of an existing document editing device. This has the effect of minimizing the impact even when

As a modification of the present invention, in addition to the reduced character pattern of 8×8 dots, it is conceivable to store patterns of 12×12 dots 1 to 1 as layout display patterns in the character generator. According to this, the characters on the layout display screen are easier to distinguish than in this embodiment.

In addition, the character generator for layout display may be configured with a ROM, which is a nonvolatile memory whose contents are saved even when the power is turned off, as in this embodiment, and a RAM that can be written to and read out at any time. is possible. If the device is configured with a ROM as in this embodiment, there is no need to write a character pattern, which will be described later, when the power is turned on, which is necessary in the latter case, and the processing when the power is turned on is simpler than in the latter case. However, in the latter case, the character pattern can be rewritten compared to the former, the number of reduced character patterns is not limited, and character patterns created by the user can also be reduced.

If the layout display character generator is configured with a memory that can be read and written at any time, it is necessary to write the layout display character pattern to the character generator when the power is turned on. 4. A method for writing the reduced pattern in the character generator for layout display, and a method for writing the reduced pattern in the character generator for normal display. A method can be considered in which a character pattern of X24 dots 1 or more is reduced by a reduction conversion circuit and written into a character generator for layout display.

In the former case, the layout display character pattern can be changed by converting the flexible disk, and in the latter case, there is no need to prepare the layout display character pattern in advance.

3, which is the character generator for displaying the layout;
The process of writing a character pattern to the character generator 2 of 12 is carried out by executing a character pattern writing process program for layout display in the same process as shown in FIG. 7 using a pattern converter of 500.

Of course, not all character patterns are legible even after reduction conversion according to this embodiment. However, as described in the embodiment, it can be said that the document is legible even on the layout display screen using the layout display character pattern obtained by the modified example of the present embodiment.

〔Effect of the invention〕

As described above, according to the present invention, the present invention comprises: a document editing processing means; a display; displaying a document edited by the editing processing means on the display in a normal document display format; The display control means displays a character pattern in a layout display format of 8×8 dots or more in a normal document display. To provide a document editing device in which the size of a character pattern in a layout display format becomes appropriate and document editing is facilitated even while displaying a layout, since the document is configured to be displayed after being reduced to a dot smaller than a dot in a format pattern. It is something that can be done.
