Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document processing device, and more particularly to a document processing device for creating and editing documents.

[Prior Art] An electronic typewriter is a typical device of this type.

Document information on electronic typewriters includes text information that stores character information and command information such as right alignment, centering, indent, and decimal tab in character codes, and frame information that stores the start and end positions of ruled lines (so-called, configuring tables, etc.). frame), format information that stores the output format for text output, each position such as light margin, soft margin, tab, decimal tab, page length, hot zone area, etc. in typewriter mode, and the print paper surface. There are roughly four types of information, including the start position of printing and the stop position information for storing the document. However, these four pieces of information have different storage formats.

In particular, in order to print out a mixture of text information and frame information on one sheet of printing paper, merge command information is included in order to mix the frame information into the text information only when printing.

That is, when printing text information and detecting the appearance of a merge command, the text printing process is interrupted and the corresponding frame information is printed.

Alternatively, there is also an apparatus that converts frame information into a character code and inserts it into text information to realize frame printing.

[Problems to be Solved by the Invention] However, in the conventional apparatus, although it is possible to print two pieces of stored information that have information in different formats, a text document and a frame, there is a drawback that they cannot be displayed simultaneously. be. Further, even when frame information is converted into a character code and mixed with text document information, it is inevitable that the shape of the frame changes as the text document is modified. If the frame is not transformed when modifying a text document, it is expected that editing will take a lot of time to change the code within the text document information.

The present invention has been made in view of the above-mentioned conventional technology, and enables text information and frame information to be displayed in a mixed manner, and allows for efficient document creation and editing without mutual display affecting each other. The present invention aims to provide a document processing device that can perform the following operations.

[Means for Solving the Problem] In order to solve this problem, the present invention includes the configuration shown below.

That is, a first storage means for storing character symbols constituting a document as code information, a second storage means for storing ruled line information constituting a frame developed in the document, and the first and second storage means a first pattern generating means for generating pattern information corresponding to code information and ruled line information in the information stored in the storage means; and a pattern generating means located at the same position in the information stored in the first and second storage means. a second pattern generating means for generating a superimposed pattern of code information and ruled line information;
A display means is provided for generating and displaying a pattern based on the code information and ruled line information stored in the second storage means using the first and second pattern generation means.

[Operation] In the configuration of the present invention, when displaying text information and frame information, a superimposed pattern is generated and displayed for code information and ruled line information located at the same position in these information. It is.

Explanation of document display (Figures 3 and 4)> Based on the RAM usage format of this embodiment described above, frame (
The principle of displaying a mixture of frames (forming a table) and text will be explained below.

FIG. 3(a) shows the internal configuration of the VRAM 4 in the embodiment.

As explained earlier, the VRAM 4 has a capacity to store display character data of 80 x 25 (=2000) display characters of CRTe a, and as shown in the figure, the CG code i and attribute i are stored for one display character data. (
i=o~1999) is assigned.

Here, the data stored in CG code i is the character code for CG in ROM2 or CGR in RAM3.
It is one of the character codes for AM30, and its location is determined by whether bit l of the corresponding attribute i is on or off.

That is, when this bit l is off, the CG in ROM2 is stored, and when that bit is on (the character pattern is created by combining), the CG in RAM5 is stored.
0 indicates that the pattern corresponding to that character code is stored.

Note that the meaning of the bit information other than bits 1 to 3 of the attributes is the same as that in the explanation of RAM3, and the display example in the VRAM4 state shown in FIG. 3(a) is shown in FIG.
Shown in Figure (b). Here, “41H” stored in CG code O is the character “A” and “42H” is the character “B”
"7AH" is an ASCII code indicating the character "Z".Attributes for each CG code (normal character display, bold character display, underline)
As a result, the results shown in the figure can be obtained.

Now, when displaying frames and text information in a mixed manner using the RAM 3 and VRAM 4 of this embodiment having such a structure, first, one line of text (character symbol code) in the text information 15 is stored in the RAM 3. The data is expanded to "CG code i part 1" in the display buffer area 25. Then, if it is determined that there is frame information corresponding to the line of note, the character code corresponding to that frame data, that is, the character code indicating the ruled line, is expanded to "CG code i that 2 degrees. However, if the corresponding If the text information to be displayed is a space, etc., expand the ruled line to CGi code part 1.Also, turn on bit 1 of the attribute where the ruled line code is expanded (synthetic display setting). If bit 1 is on, character patterns corresponding to the character codes stored in CG codes i, 1 and 2 are generated from the CG in the ROM 2, and the logical sum pattern is stored in the CGRAM 30. , and assign the corresponding code to the VRAM
Expand to 4. Note that when bit 1 in the attribute is off, the character code in CG code i part 1 is written as is to the corresponding address in the VRAM 4. As a result, a display as shown in FIG. 4 is created. Hereinafter, when the operator edits text, for example, inserts a single character, the operator processes the corresponding text information 15 and performs the above-mentioned process, thereby editing the text without affecting the frame at all. It becomes possible to do this. The same applies when editing frames.
After performing the editing contents on frame information 25,
By executing the above-described processing, it becomes possible to perform display without affecting the text at all.

In the display example of FIG. 4, 40 is a message line that displays the title name of the displayed text information and message information. 41 is a format line for displaying output format information 16 of the text shown in FIG. 2; 42 is a display character indicating a return code. 43 is the second
This is a display character for the start code (DCH) for merging the frame information 17 shown in FIG. 2A, and 44 is a display character for the end code (DDH). 45 is a display character indicating a tab. 46 is the merged frame information 20 shown in FIG. 2(a) expanded into a display code and displayed.

Explanation of processing procedure (Figures 5 to 7)> Hereinafter, C related to one-line display based on the configuration and principle of this embodiment described above.
The processing contents of PU1 will be explained according to the flowchart of FIG.

First, in step S1, text information 15 to 1
Extract information for a line. Taking as an example the line indicating that frame information is being merged in FIG. 4, it is from the merge start code (DCH) 17 to the margin end code (DDH) 18 in the text information 15. Note that the merge end code (DDH) also has a line feed function. Next, the process proceeds to step S2, where the extracted information is displayed in the display buffer area 2.
5 (CG code i part 1). Then, the process proceeds to step S3, and a determination process is performed by scanning the directory 9 to determine whether the display text is merged with frame information and whether or not the corresponding frame information exists. If there is a frame merge and the frame exists, the process advances to step S4. Further, if there is no frame merging, or if there is, but the frame information does not exist, the process advances to step S6.

In the case of the embodiment, frame information with the title "FRAME" is merged with the text information 15, and the frame information exists in the area 20 of the RAM 3. Therefore, the process proceeds to step S4.

In step S4, the line information of the frame information 2o is developed, and a process is performed to determine whether or not there is a frame line to be displayed on the corresponding display line. If there is a frame line to be displayed, the process proceeds to step S5; if there is no frame line to be displayed, the process proceeds to step S6.
Proceed to.

Here, display codes such as "(underline)" or "(double underline)" are used for the horizontal line and "1" (stroke), "II" (double stroke), etc. are used for the vertical line to display the frame. especially,
A special display code is prepared in the CG code stored in the ROM 2 mentioned above. In the merge command display line, there is a frame of horizontal lines to be displayed. In step S5, the display buffer area 25
Processing processing (expanding to CG code i part 2) is performed to add frame information to the information stored in , and step S6
Proceed to. In step S6, the information stored in the display buffer 25 is expanded into the VRAM shown in FIG. 3(a), and the process ends.

Details of the frame information development process in the display buffer area 25 in step S5 are shown in FIG. 6 and will be described below.

First, the correction process is started from the column-based display information 26 indicating the first character of the display buffer area 25. In step S7, it is determined whether a frame line exists at the display position of the corresponding column. If a frame line exists, the process advances to step S8; if no frame line exists, the process advances to step S13.

Now, in step S8, when developing the frame information in the display buffer area 25, a display code of the frame information is selected. For example, the display code 43 in FIG. (empty). If it is a space, the process advances to step SIO, and the display code selected in step S8 is stored in CG code No. 1 of each column.

Also, if there is no space, that is, if the character code is already stored, proceed to step Sll, turn on bit 1 of the attribute (composite display),
The code obtained by selecting first is stored in CG code No. 2.

In this way, when the frame information in one column is expanded to the display buffer area 25, step S1
In step 3, it is determined whether the column of interest is at the final position of the row, that is, whether or not the development process for one row of frame information in the display buffer area 25 has been completed. If it is determined that the processing has not been completed, the next column of interest is updated, and the processing from step S7 onwards is repeated.

Next, the VRA of the information developed in the display buffer area 25, which is the process of step S6 in the flowchart of FIG.
Expansion processing to M4 will be explained using FIG. 7.

First, in step S15, the leading position of the display buffer area 25 for the developed light and the leading position of the VRAM 4 for the developed light are determined.

Next, the attribute of the column of interest in the display buffer area 25 is checked, and it is determined whether any of bits 1 to 3 are turned on. If all of these bits are off, the displayed character is determined only by the character code stored in CG code No. 1 in the display buffer area 25, so the character code is stored in the VRAM.
4 in the corresponding CG code, and each bit state in the attribute is also copied to the corresponding attribute in VRAMJ.

On the other hand, if at least one of bits 1 to 3 of the attribute of the column of interest in the display buffer area 25 is on, the process proceeds to step S17, and the character codes corresponding to the CG codes 1 and 2 are set. A character pattern is generated from the CG in the ROM 2, and a composite pattern of them is generated. In the next step S18, the generated composite character pattern is stored in the CGRAM 30, and the corresponding character code is stored in the CG code of the VRAM4. Then, in the next step S19, bit l of the corresponding attribute in the VRAM 4 is turned on, and bits 0, 4, 6 of the attribute in the display buffer area 25 are turned on.
．． Copy 7 to the VRAM4 (7) attribute.

In this way, when the character code in the VRAM 4 and the bit setting in the attribute for one column of interest are completed, it is determined in the next step S21 whether or not these processes have been performed for one display line. If it is determined that the process is incomplete, the process proceeds to step S22, where the columns of interest in the display buffer area 25 and VRAM 4 are updated, and the processes from step S16 onward are repeated until it is determined that the process is completed in step S21.

The processing described above is performed, for example, every time the operator edits text information. As a result, for example,
Even if the operator edits the text, the frame will no longer be distorted as in the past.

Conversely, when editing a frame, the same principle will be used to avoid affecting the text. Therefore, each editing process in a state where text and frames are mixed can be significantly improved.

Description of other embodiments (Figs. 8 and 9) In the above embodiment, the area of the CGRAM 30 for overlapping characters is
Although it is necessary to secure a sufficient amount on the AM3, if the sufficient amount cannot be secured, the steps from step S8 to step S12 in FIG. 6 can be replaced with the flowchart in FIG. 8.

The process will be explained below using this flowchart.

First, in step S23, when developing frame information in the display buffer area 25, the type of display code of the frame in the column of interest is determined. Then, in step S24, the frame display code is "1 (stroke)" or "
Determine whether the vertical line and horizontal line do not intersect, such as - (underline), or if there is a combination of vertical and horizontal lines, such as ``1'' or ``above''. If there is an intersection, the process proceeds to step S26, and if there is no intersection, the process proceeds to step S25.In step S25, the display buffer 2
The bit 7 of the attribute of the corresponding column position information in 5, which indicates the inverted display, is turned ON, and the process ends. In step S26, both the blink bit 6 and the inverted display bit 7 of the attribute are turned off.
Process N.

FIG. 9 shows an example of display according to this embodiment. According to this embodiment, although it is not possible to obtain a one-to-one display result with the printed result,
The GRAM 30 is virtually unnecessary, which is extremely effective considering the limited RAM area and its processing speed.

[Effects of the Invention] As explained above, according to the present invention, two different forms of information, text information and frame information, are simultaneously displayed as printed images on the same screen, and moreover, these different forms of information are displayed during editing. The operability of document editing is greatly improved because the documents do not influence each other.
