Abstract

PURPOSE:To reduce the capacity of a dictionary memory by converting patterns of respective ruled lines in a character area in which plural ruled lines intersect into bit information and operating patterns formed by these ruled lines. CONSTITUTION:When ruled line data is inputted from a keyboard 2, said data is stored in a video ram 4 and displayed on a CRT5. When ruled lines of large diameter are drawn in the same direction in this way, they are stored in the ram 4 as they are. When vertical small diameter ruled lines are drawn in different directions, they intersect old large diameter ruled lines. A pattern recognizing section 8 detects intersection of lines of different diameters, calls out old ruled line data in the same character unit from the ram 4, converts the data into bit information, and outputs to a temporary memory 11 through a ruled line synthesizing device 9. On the other hand, new ruled lines that generate intersection input bit information to the device 9 and add to bit information of old ruled lines stored in the device 11. This bit information is converted to a ruled line pattern expressed in a conversion table 10 and stored in the ram 4. Thus, ruled lines of unified diameter are stored.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a ruled line creation method and apparatus suitable for a word processor.

(Prior art) Tabulation work requires drawing rules using thick and thin lines, but at edges and intersections, it is necessary to draw rules using a combination of the thickness and direction of the ruled lines as shown in Figure 1 (A). Various patterns (a)
to (even) occur, and a large-capacity dictionary memory is required to accommodate all of these patterns. ) (chi) (nu) (power), the same figure (
As shown in B), display aligned to one of the wire diameters,
This method had the disadvantage that the resulting borders were irregular and messy.

(Objective) In view of these problems, it is an object of the present invention to propose a novel parallel line creation method that can tabulate patterns while sequentially composing patterns at locations where ruled lines intersect.

Another object of the invention is to provide a device for implementing the above method.

(Structure) Therefore, details of the present invention will be described below based on illustrated embodiments.

FIG. 1 is a block diagram of a word processor to which the ruled line synthesis device of the present invention is applied, and the reference numeral 1 in the figure is
is a central processing unit that controls the entire system based on the data input from the keyboard 2. It accesses the dictionary memory 3 storing kana-kanji conversions, symbols, etc. based on the reading data input from the keyboard, and executes the specified data. It is configured to output patterns of kanji and symbols to a video ram 4, and display and print them on a CRT 5 and a printer 6.

7 is a 'J' 4-line creation device which is a characteristic part of the present invention, and reference numeral 8 in the figure is a pattern recognition unit that combines the previously inputted ruled line data (hereinafter referred to as old ruled line) and the currently inputted ruled line data. The ruled line data (hereinafter referred to as new ruled line) is the same character i.
t (If the ruled lines are stored in i, that is, if the ruled lines are intertwined, this is detected, and it is determined whether the wire diameter of the new ruled line overlapped with the old ruled line is the same or not, and if the wire diameter is the same, The dictionary memory 3 is accessed, a predetermined pattern is called up, and this is stored in the address of the video ram where the old ruled line is stored.If the old ruled line has a different wire diameter, the pattern of the old ruled line is stored in the video ram address. 4 and read out the ruled line pattern in the direction of the arrows as shown in Figure 3 (&) according to the wire diameter data (Table 1). 00.01.00.01 for the small diameter in the direction
In (C), the large diameter in the vertical direction is 10.00.10.00
, and the half lines in (d) and (e) of the figure are io, 00.
It is configured to convert into bit information such as 00.00 and 00.00.00.01 and output it. 9
is a ruled line synthesis device configured to generate bit information by adding the bit information of the old ruled line from the video ram 4 converted by the pattern recognition unit 8 and the bit information of the new ruled line from the keyboard 2. . Reference numeral 10 denotes a conversion table, which is configured to generate a corresponding ruled line turn based on bit information from the ruled line synthesis control device 9. Reference numeral 11 denotes a temporary storage device that temporarily stores data in the calculation process of the ruled line composition control device.

Next, the operation of the apparatus configured as described above will be explained based on the flowchart shown in FIG.

When ruled line data is input from the keyboard 2 for tabulation, it is stored in the video ram 4 via the central processing unit 1 and displayed on the display 5.

When large-diameter ruled lines are drawn one after another in the same direction, for example, the horizontal direction (Fig. 5a), they do not intersect with each other, so they are stored in the video ram 4 as they are.
Next, when a narrow vertical ruled line is drawn in a different direction (FIG. 5B), it intersects with the old large-diameter ruled line (FIG. 5C). The pattern recognition unit 8 detects this intersection 2 of different wire diameters,
Recall the old ruled line data existing in the same character unit from the video ram 4, and read the bit information (00, 10, 00,
10) and output it to the time storage device 11 via the ruled line composition device 9. On the other hand, the new ruled line where the intersection occurs is determined by the pattern recognition unit 8 with bit information (01, 00, 00,
00) is input to the ruled line synthesis device 9), and is added to the bit information of the old ruled line stored in the temporary storage device 11 (00).
,10,00,IO+01.00゜00.00) and1
A new combination of both ruled lines! E line pattern bit information (
■ Create 01, 10, 00, 10). This bit information is input into the conversion table 10 and converted into the ruled line pattern represented by this (FIG. 5e) (2), and then input (2) to the address of the video ram 4 from which the old ruled line was called. As a result, ruled lines with uniform wire diameters in each direction are stored in the video ram 4, and front ruled lines with uniform diameters in each direction are displayed and printed by the CBr 4 and the printer 6 (FIG. 5f). Needless to say, if ruled lines of the same diameter are intertwined, the ruled line pattern stored in the dictionary memory 3 is called [phase],
This is output to the address where the old ruled line of the video ram 4 is stored, and is displayed and printed.

In addition, in this embodiment, the case where the ruled lines of two trees with different wire diameters intersect at right angles is taken as an example, but needless to say, the same applies to the case where the ruled lines of the same wire diameter intersect or intersect diagonally. It is clear that it can be synthesized.

(Effects) As described above, according to the present invention, the pattern of each ruled line in a character area where a plurality of ruled lines are intertwined is converted into bit information, and the pattern formed by these ruled lines is calculated. Therefore, not only the capacity of the dictionary memory can be reduced, but also all ruled line patterns can be handled, making it possible to tabulate the edges with fine details.
