Abstract

PURPOSE:To obtain easily plural kinds of ruled line patterns by drawing a ruled line information obtained from a ruled line information buffer, in a specified entry, in case when an instruction for drawing a ruled line is given from an operator. CONSTITUTION:A document character-string data buffer 21 and a ruled line information buffer 22 are contained in a main memory 12, and a document character-string data and a ruled line data are separated and managed. In this state, when an operator designates a classification of a ruled line by a keyboard 17, a ruled line information of a specified entry consisting of 2-bit in the buffer 22 is outputted. In this case, a ruled line key gives instructions for shifting to a ruled line generating mode, to a CPU11. Also, a selection/execution key selects a kind of a ruled line displayed on a CRT at present, and gives instructions for completion of the ruled line drawing work, to the CPU11. Also, the following candidate key gives instructions to the CPU11 so that the ruled line displayed at present is changed to other kind of ruled line.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a document creation device that creates and prints a number of types of ruled line patterns.

[Technical background of the invention and its problems]

In a Japanese word processor, since the target of the information center is Japanese text, it is essential to have the ability to create numerical tables and charts - and to create these various tables, vertical and horizontal It is a ruled line. In conventional Japanese word processors, the following methods were used to handle ruled lines.

This is a method that manages ruled line information independently of character strings, and in this method, even if the character string moves up, down, left, or right during proofreading or editing, the drawn ruled lines remain unchanged. In Japanese word processors that adopt this method, ruled line information is stored in a buffer independent of text buffer 1, and even in CI (T display), ruled line information is processed in the form of attribution pits. In this case, the ruled lines are printed according to the information from the attribution bit or the ruled line print command1, that is, the ruled lines are handled separately from the document string in both internal processing and external output. .

The feature of this method of line processing is that, as mentioned above, even if the text string moves up, down, left, or right due to proof editing, the internal processing is separated from the text processing, so the line position remains unchanged. The reason is that the shape of the table drawn with ruled lines does not collapse. However, in Japanese word processing sensors that conventionally perform this type of ruled line processing, the management and processing of ruled line information becomes complicated, so it is necessary to handle multiple types of @kana patterns (for example, thick lines, rasa nato). There was nothing to eat.

[Purpose of the invention]

The object of the present invention has been made in view of the above circumstances.
The method for processing ruled lines is to handle character string data and ruled line data separately for internal and external processing, but it is also possible to handle multiple types of vertical data. Specify the desired type of front from among them with simple operations,
Another object of the present invention is to provide a Japanese word processor that can be modified.

The ruled line information storage unit is composed of a plurality of entries for storing ruled line type information for each character area, and is provided with an input means for the operator of the word processor to specify the type of ruled line. Each time an instruction is given, the ruled line type information of a specific entry in the ruled line information storage section is updated.

Furthermore, a storage section for separately storing ruled line type information is provided,
When the operator issues an instruction to draw a ruled line, the m type of ruled information obtained from the storage section of C is written into the specific entry.

FIG. 5 shows the configuration of ruled lines within one character area expressed on a CRT screen or printed paper. A ruled line consists of six elements (51
It is divided into 56). Border elements (51 to 56
) have a corresponding relationship with the intra-character position end IJ (41 to 46), respectively. That is, for example, the previous entry within the character (4
If ruled line information, which will be described later in 1), is specified, the ruled line element 51 will be displayed or printed.

Table 1 shows the definition of 2-bit information for each intra-character position entry (41 to 46).

One dollar! 1 As shown in Table 1, this 2-bit information indicates the presence or absence of a ruled line in the ruled line element (51 to 56), and the flI type of the ruled line to be displayed or printed on the ruled line element (51 to 56). This is information that specifies. In this example,
It is set up so that you can draw three types of ruled lines: thin lines, thick lines, and dotted lines.

Normally, the cursor with the total height and width shown in Figure 7(a) is displayed in Table 7J-
However, when creating ruled lines, excluding 81'', and in MJ normal mode, it is necessary to specify the in-line horizontal ruled line and the inter-line horizontal ruled line separately, so when creating an in-line horizontal ruled line, the same figure (not shown in BL) is used. A half-height cursor, and a lower half-height cursor shown at <c> in the figure is used when creating horizontal ruled lines between lines.

71-74 and 78-82 in the figure are usually cR'l
・There are many important issues inside the control LSI.

Hereinafter, the operation of the present invention will be explained in detail with reference to the drawings.

When drawing ruled lines on the document currently displayed on the screen of the CRT 18, the operator presses the ruled line key 61.

When the diagonal key 61 is pressed, the thousand-code corresponding to the (1') key 61 is read into the CPU 11 via the oP 13. By inputting this key code, crLllll branches the control program to the rule (+3) and the creation program. 1. To set the cursor to middle height 1119, select the upper height cursor "j'□ 7 fJ (1) )

;'i) B is set in King's Memo', 11121.

When the trivia key 61 is pressed down, you can freely select whether the horn that is displayed first is an upper half-height cursor or a lower half-height cursor. This implementation 9-11
, when the vertical J key 61 is pressed, a lower half height cursor is displayed.

Therefore, among the parameters set above, CPU II
CD parameter B for displaying the lower half height cursor
The result of writing to IAR73 and CIRAR74 is
A lower half-height cursor is displayed at the position on the CR1 screen specified by the cursor address register held down by cR'revc4). The CPU 11 sets the parameter B to CR'r c
At the same time, a flag is set in the main memory 12 to indicate that the current half-height cursor is being displayed.
′←j..., the operator moves the cursor (62 to 65)
Press to move the Nakatakahata cursor to the starting point of the fth scent. When the left and right cursor movement keys 63 and 64 are pressed, the value of CIDAR 72 is set to 1 by the CPU 11.
Subtract or add 1, and the P1 width cursor moves left and right one character at a time.

On the other hand, −F lower ILi (7) car 7 /I/,
When w jfI'J+ km 2.65 is pressed, the half-corridor width cursor moves 1/2 line at a time to the upper and lower giant 1 by 4h. CPU that controls this cursor movement in 1/2 line increments
The operation of II is shown in FIG. 9 as a flow chart.

Operator QF moves his/her cursor to line 1 according to the 17 works mentioned above.
After the cursor moves to the starting point i1 and 7, it instructs the CPU 13 that this cursor position is the starting point by pressing the cursor key 61. The CPU 11 reads a line from the keyboard 17.
Upon receiving the code, the CPU 11 accesses the CDAR 72 and reads the cursor display address. Furthermore, CP
U11 accesses the memory in the main memory 12 (ifJ area 237. Then, cPulx accesses the note t= and SC4 areas 23 and 24 in the main memory 12, and retrieves the 11th page infix digit (1), which is currently indicated by the cursor. Sentences per line′+kai,
The number of lines per page is 7n) and the displayed car number.

Then, from the previously calculated ruled line starting point door line column position and these pieces of information, the address of the entry at the hexagram starting point position in the ruled line data buffer 122 is set at a[post]. Fourth, CPU
111-i flag 25 is checked to determine whether the starting point is within a line or between lines.

Next, the operator uses the left and right cursor movement keys 63 and 64 to draw horizontal lines, or uses the up and down cursor movement keys 62 and 65 to draw t4: ruled lines. Move the middle-takahata cursor to the end point of the ruled line. Then, the player presses the leg key 61 again to instruct the CPU 11 about the end point of one win. CPU II keyboard 1
When the ruled line key code is received from 7, the address of the hexagram end point position 1b-entry in the ruled line data banoff 122 is outputted using the same cow 111 as that used for inputting the starting point of the ruled line. Then, Cf'[J]1 checks the flag 26 to determine whether the end point is within the line or between the lines.

For example, assume that point 91 of the anzu image shown in FIG. 10 is designated as the Yu point, and point 92 is designated as the end point. CPLIII is point 91 and point 9
Since the line position of 2 is impressive, I judge this to be a ``柘荊'' and perform the following processing. First, the area 26 of the main menu 12 is accessed to read the ruled line type information. This is set to either the 2-bit information (01)2 or (10)21(11)2 shown in Table 1. Temporarily, thin line information (01)
Suppose that 2 is specified. Next, CPTJII inputs the data whose character position entry 46 is (01)2 to the starting point entry address in the field line data vanofer 22 with -V,
! -Include. This takes into account that the starting point is set between lines. There is a possibility that the data at this entry address is not specified in the lever of this write, and there is a possibility that there is an entry '41.' in the other characters. Reach,
No modification is added to the specification of 45. At the same time, the CPU 11 writes the character position 1μ to the entry address in the ruled line data bar 22 corresponding to the part between the starting point and the ending point (t).
The data whose entries 45 and 46 are (01)2 are successively saved. Furthermore, CPLIII has a 1μ entry 45 (01) at the entry address corresponding to the end point.
, ) 2 Yr0 This result points 91
A thin horizontal ruled line is drawn between and point 92.

Instead of thin lines, the operator accesses other types of ruled lines, such as the large area 27, and inputs ruled line type information (01)2→(]0),→(
11,)2→(01)2・(i.e., thin line→thick line→dotted line). If you want to change the thin line to thick line 1, just press the next option button once.

C1-'Ull changes the data to be written to (10)2, writes data to each entry address described above, and draws a thick ruled line.

When the operator selects P9 [Wild Chrysanthemum of Desire], the operator selects/analyzes the Jitsugi program and exits the ruled line creation mode. At this time, the medium-high width cursor display hook is set, and the cursor is set to the normal full height of 1.

Suppose that two points, points 91 and 92, are specified and a thick line is drawn using a new horizontal ruled line. Then, thick line information is stored in the ruled line learning information storage area 23 in the main memo January 2. Therefore, in the next operation, when the operator instructs to draw a horizontal ruled line between points 93 and 94, the CPU II specifies thick line information in the ruled line learning information storage area 26 in the main memory 12. Therefore, draw a thick line between points 93 and 94.

Next, the rule deletion and front door correction modes will be explained.

The basic operation is the same as creating ruled lines. In ruled line deletion mode, C1-'Ull is specified by the medium-height cursor.
%T in the entry address data corresponding to the points
Change the Bungyo internal alignment entry to (00)2. As a result, the front axis of the specified portion is deleted.

It is activated by pressing the next fJ-auxiliary key 67. Therefore,
The operation of the CPIJ 11 in this case is the same as the operation when the next candidate key 67 is pressed in the above-described ruled grid creation.

In the above explanation, the next candidate key is used to request the update of the ruled line pattern, but other different keys may also be used. (Position en) Bit lz'lk of IJ character position false entry
