Description

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

(Prior art) Tabulation work requires drawing lines using thick and thin lines, but at edges and intersections, various combinations of the thickness and direction of the ruled lines can be drawn, as shown in Figure 1a. Patterns are generated, and a dictionary memory with a large capacity is required to accommodate all of these patterns. blood,
As shown in FIG. 2B, the wire diameters are displayed and printed according to one of the wire diameters, which has the disadvantage that the resulting table lines are irregular and look messy.

(Objective) In view of such problems, an object of the present invention is to provide a novel ruled line creation device that can create beautiful front ruled lines while sequentially synthesizing patterns at locations where ruled lines intersect.

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

FIG. 2 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 controls the entire system based on data input from the keyboard 2. The central processing unit accesses the dictionary memory 3 in which kana-kanji conversions, symbols, etc. are stored by inputting reading data from the keyboard, and converts predetermined kanji and symbol patterns into the video RAM 4 (an example of video memory).
It is configured to output the data to a CRT 5 or printer 6 for display and printing. 7 is a ruled line creation device which is a characteristic part of the present invention, and is designated by the reference numeral 8 in the figure.
In the pattern recognition section, if the previously input ruled line data (hereinafter referred to as old ruled line) and the newly inputted ruled line data (hereinafter referred to as new ruled line) are stored in the same character unit, that is, the ruled line is In the case of interlacing, this is detected, and it is determined whether the wire diameter of the new ruled line superimposed on the old ruled line is the same.
If the wire diameters are the same, the dictionary memory 3 is accessed, a predetermined pattern is called up, and this is stored at the address of the video ram where the old ruled line is stored. On the other hand, if the wire diameters of the new and old ruled lines are different, the old ruled line pattern is read out from the video ram 4, and the ruled line pattern is sequentially changed according to the wire diameter data (Table 1) in the direction of the arrows as shown in Figure 3a. , Table 1 Blank Thin diameter Thick diameter 00 01 10 The narrow diameter in the horizontal direction shown in b in the same figure is 00, 01, 00, 01.
The large diameter in the longitudinal direction of c is 10,00, 10,00, and the half line of d and e in the same figure is 10,00,00,00 and 00,
It is configured to convert and output bit information such as 00, 00, 01. Reference numeral 9 denotes 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. There is. Reference numeral 10 denotes a conversion table, which is configured to generate a corresponding ruled line pattern 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.
In this way, if you draw thick ruled lines one after another in the same direction, for example the horizontal direction (Fig. 5a), they will not intersect with each other, so the video ram 4
will be stored in. Next, when a thin vertical ruled line is drawn in a different direction (FIG. 5b), it intersects with the old thick ruled line (FIG. 5c). The pattern recognition unit 8 is
The intersection z of these different wire diameters is detected, the old ruled line data existing in the same character unit is called from the video ram 4, and the bit information (00, 10, 00, 10) is
, and output it to the temporary storage device 11 via the ruled line synthesis device 9. On the other hand, new ruled lines that intersect are identified by the pattern recognition unit 8 as bit information (01,
00, 00, 00) is input to the ruled line synthesis device 9 and synthesized with the bit information of the old ruled line stored in the temporary storage device 11 {(00, 10, 00, 10) + (01, 00, 00,
00)} and create bit information (01, 10, 00, 10) of a new ruled line pattern by combining both ruled lines. This bit information is input into the conversion table 10 and converted into the ruled line pattern (FIG. 5e) represented by the conversion table 10, and then inputted into 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 CRT 5 and printer 6. Needless to say, if ruled lines of the same diameter are intertwined, the ruled line pattern stored in the dictionary memory 3 is called up, and this is output to the address where the old ruled line is stored in the video ram 4, and displayed and printed. do.

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

(Effects) As explained 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 can the capacity of the dictionary memory be reduced, but also the unsightliness of intersection processing can be eliminated.
It is possible to create tabulations with fine grains.
