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 for inputting, editing, printing, etc. The present invention relates to a document editing device having a function of displaying the layout of a document using reduced characters made up of dot matrices stored in the character generator.

[Background of the invention]

In general, the above-mentioned document editing device has an input section for inputting characters, symbols, etc., a display section for displaying input characters and symbols, created and edited documents, and a control program and information on already created sentences 6fx. It is roughly divided into a temporary storage section that stores information, a printing section that prints completed documents on paper, and a control section that is comprised of a computer or the like that controls each of the above 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 and rearrange a created document by checking the layout and balance of the entire page of the document.

Therefore, in conventional document editing devices, in order to check the layout, balance, etc. of the created document, a display device that displays the layout of the entire document page (hereinafter referred to as layout) is installed separately from the display device for displaying the document. Some are built-in devices, while others are designed to display the layout on the screen using screen switching means during editing and proofreading of a document.

However, in the former case, a display device for displaying the document and a display device for displaying the output are required, which complicates the configuration of the display device and increases the resolution of the display device.
Since the document and the layout are displayed at the same time, editing processes such as document correction and replacement are slow.

(Bota, both the former and the latter are Leila) = + On the display screen, the characters are replaced with alternative symbols that are far different from the actual characters, such as ``book'' or ``★''. Therefore, the user simply checks the layout of the document on the layout display screen.

Particularly in the latter case, in order to check the layout taking into account the flow and internal nature of the document, it is necessary to frequently switch between the document display screen and the layout display screen, and this operation is extremely complicated. Furthermore, since it is not possible to confirm the existence of a document on the layout display screen, editing processes such as correction and proofreading of the document cannot be performed on the layout display screen. Unfortunately, even when editing a document while taking the layout into consideration, the document display screen and the layout display screen must be frequently switched, and this operation also becomes very complicated.

[Purpose of the invention]

In view of the drawbacks of the conventional example, it is an object of the present invention to enable layout display using reduced characters, to enable editing work on the layout display screen, to shorten the time required to complete layout display processing, and to provide reduced characters that are convenient for practical use. An object of the present invention is to provide a document editing device having a layout display function.

[Summary of the invention]

The present invention provides separate character generators for storing reduced character patterns used for layout display and character generators for storing character patterns used for normal document display, and selectively uses both character generators. It's what I chose to do.

05, a CRT 123, an FDC 306, an FDD 125, a printer controller 307, and a key controller 308.

A CRT 123 related to a display section and an FDD 125 related to a temporary storage section are installed substantially at the front of the main body 121.

Now, when the power is turned on in the configuration described above, this device stores the FD according to the program in the boot FROM 302.
A program that operates as a document editing device having the flow shown in FIG. 3, which is stored in the flexible desk in the D 125, is transferred to the program memory 303, and then transferred to the program memory 303 as shown in FIG. It starts operating as a document editing device according to a program with a flow. 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, an input processing program or an editing processing program having a flow as shown in FIG. 4 or 5 is executed. The document being inputted or edited is stored in the program memory 303 in Figure 4 or 5.
The data is displayed on the CRT 123 by a code refresh method using the code refresh memory 310 according to a flowchart shown in the figure, such as manual processing or an editing processing program. Commands for processing associated with inputting and editing characters in the document are input using the keyboard 122 and are detected by the CPU 301 via the human key controller 308 . C
According to the input, the PU 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 10 is changed to change the display text on the CRT 123. At this time, the CPO 301 also changes the Bunka information in the part of the program memory 303 where the police box information is stored (referred to as the police box buffer).

When a layout display command is input from the keyboard 122, the CPU 301
detects the layout display execution command, and the CPU 301U
The layout display program stored in the program memory 303 and having the flow shown in FIG. 6 is executed.

When the layout display process is started, the CPU 301
A command is given to the RT controller 305 to erase the code refresh type document display 'ecRT 123 by the input processing or editing processing program shown in FIGS. 4 and 5. Next, the dot refresh memory 311 is busy initialized, and the CPU 301 is activated by the CRT controller 305.
Even if you command display using the dot refresh method, CR will not occur.
Nothing is displayed on T123. After this process is completed, the contents of the dot refresh memory 311 are
CRT controller 30 to display on RT123u2
By giving a command to 5, the contents of the dot refresh memory 311 are displayed on the CRT 123. Next, character codes are sequentially read from the document buffer in the program memory 303, and the display position of the character when displaying the layout (
After the calculation is performed by the rcPU 301, one reduced character Bakun is written to the second character generator 312 by the reduced character writing processing program having the flow shown in FIG. 7 based on the display position information and the character code. It is then read out and placed in the corresponding location in the dot refresh memory 311. By repeating this process 9 times until the layout display for one page is completed, 0. A layout with reduced characters is displayed on the CRT 123.

When the layout display for one page is completed, select whether or not to perform editing processing on the layout display screen. !ll
1. Inputting commands for editing processing and updating the contents in the text screen buffer. The flow of the editing processing program is shown in FIG. Correction, movement, format change 5 Determine which of the document layout changes corresponds to and perform each process. If none of the instructions apply, return to inputting instructions for editing content and wait for new instructions.

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

In the case of correction, by specifying the correction range and inputting the character to be corrected from the keyboard 122, the CPU 301 replaces the corresponding character code in the document buffer with a new character code according to the program, and then inputs the character code in the document buffer. −
Replace the whole thing with a new one.

To move, use the keyboard 122 to specify the range of character strings to be moved backwards and the destination! 0CP0.301 moves character codes within the document buffer according to the program and rearranges the character codes.

In the case of changing the format, by instructing a new format from the keyboard 122, the format information in the document buffer is rewritten according to the CPU 3011''J 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 using the keyboard 122, the CPU 301 rewrites the 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 layout after the editing process is displayed on the CRTl 23 by returning the layout display process to the starting point of character display in the layout display program as shown in the flowchart of FIG. to be displayed.

When the editing process is finished or no editing process is to be performed,
The layout display is continued until the layout display end instruction is given, and the CPU 301 HCRT controller 305 is instructed 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.

By using a document editing device that has the structure and operation described above, it is possible to edit characters on the layout display screen using the conventional 1-*
” or “★”, but can be displayed as readable characters as shown in FIG. 14.

Therefore, by displaying the layout of the document in reduced characters, it is possible to read the document displayed on the P5 layout display screen, and it is also possible to check the layout of the document according to the content of the document. It becomes possible. In addition, since the content of the document can be read on the layout display screen, editing processing such as correcting, inserting, and moving text can be displayed in the layout using a program with the flow shown in Figures 6, 7, and 8. What you do on the screen becomes easier.

Furthermore, if the reduced character pattern for displaying the layout is an 8 x 8 dot pattern as in this example, JIS 1
Since a standard 3,418-character character pattern can be stored in a single 32-byte mask ROM, the board area occupied by the character generator that stores character patterns for layout display can be reduced, and it can be easily integrated into the control circuit of existing document editing devices. Even when it is added, it has the effect of minimizing its influence.

As a modification of the present invention, in addition to the 8x8 dot reduced character pattern, a 12x12 dot pattern may be stored in the character generator as a layout display pattern. According to this, Leila 1-f
This has the effect that the characters on the f-display screen are easier to distinguish than in this embodiment.

In addition, the structure of the character generator for displaying the layout includes ROO12, which is a non-volatile memory that retains the contents even when it is divided, especially in the /do embodiment.
It is conceivable that it is configured with a RAM that can be read and written at any time, but if it is configured with a ROM as in this embodiment, there is no need to write character patterns, which will be described later, when the power is turned on. This has the effect that the processing at the time of input is simpler than in the latter case. In the latter case, since the character pattern can be rewritten compared to the former, the number of reduced/lowercase character patterns is not limited, and the character pattern created by the user can also be reduced.

If the layout display character generator is configured with RAM, it is necessary to write the layout display character pattern to the character generator when the power is turned on. is written into the layout display character generator, and the 24x24 dot character pattern stored in the normal display character generator is reduced by a layout display character pattern writing processing program having the flow shown in Figure 9. , a method of putting your lips into a character generator for displaying the layout can be considered.

For MFF users, the effect is that the character pattern for displaying the layout can be changed by replacing the flexible disk, and for the latter, there is no need to prepare a character pattern for displaying the layout layout. effective.

The process of writing a character pattern into the character generator 312, which is the character generator for layout display, is carried out by executing a character pattern write process program for layout display having the flow shown in FIG. The layout display character pattern writing processing program is generally kmx as shown in FIG.

To reduce a 24x24 dot pattern to an 8x8 dot pattern, set each constant in the conversion formula to j = = 3 m = n = 3, and create a layout display character pattern with the flow shown in Figure 9. By the writing processing program, the 10th
A character pattern represented by a matrix pattern of 24 x 24 dots is read out from the character generator 304 in three rows at a time, and the character pattern is converted into a logical formula % formula % by converting the character pattern into 3 dots in the vertical and horizontal directions, a total of 9 dots, as shown in Fig. 11. ) ) ) ) (In Figures 10 and 11, the shaded areas are logical "1"
shall be. ) A reduced pattern for 91 lines is created by sequentially converting to 1 dot according to Accordingly, a dot matrix pattern of 8×8 dots is stored in the character generator 312. Figure 12 shows 24 before reduction.
Figure 13 shows an example of an 8x8 dot pattern after reduction.

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

〔Effect of the invention〕

According to the present invention, it is possible to display a layout using reduced characters, which improves the operability of conventional document editing devices, to enable editing processing on the layout display screen, and to shorten the time required to complete the layout display processing. This makes it possible to further improve the operability of the document editing device.
