Abstract

PURPOSE:To execute an elaborate tabulation by converting a pattern of each ruled line in a character area in which plural rules lines are confounded to bit information, and calculating the pattern formed by these ruled lines. CONSTITUTION:Inputted ruled line data is stored in a prescribed address of a video memory, and in the case data inputted continuously is ruled line data, and also, exists in the same character unit as ruled line data inputted in the previous time, whether the line diameters of two ruled lines are different or not is decided. As a result, in the case the line diameters are different, the ruled line data inputted in the previous time of this character unit is called from the video memory and converted to bit information, and also, ruled line data inputted this time is converted to bit information. Subsequently, two bit information is synthesized, and based on this bit information, a ruled line pattern is generated, and reinputted to the address which executes a call of the video memory. In such a way, the capacity of a dictionary memory can be made small, and an elaborate tabulation can be executed.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ruled line forming method particularly suitable for a word processor.

[0002]

2. Description of the Related Art A table drawing operation requires ruled line drawing using thick lines and thin lines, but at the ends and intersections, as shown in FIG. 1A, the combination of ruled line thickness and direction is used. Various patterns (a) to (t) occur, and a large-capacity dictionary memory is required to support all of these patterns. Therefore, in a normal word processor, a part (rule) where ruled lines with different lengths cross each other is required. ) (Ho) (to) (chi) (nu) (mosquito)
However, as shown in FIG. 3B, the lines are displayed and printed on one of the lines, and the resulting ruled lines are not uniform and unsightly.

Incidentally, in relation to the creation of ruled lines, Japanese Patent Laid-Open No. 56-2
Although there are inventions disclosed in Japanese Patent Application Laid-Open No. 079 and Japanese Patent Application Laid-Open No. 58-27229, the present invention is different from these inventions in view of the object, constitution, effect and the like.

[0004]

In view of the above problems, the present invention aims at proposing a new ruled line creating method capable of tabulating while sequentially synthesizing patterns at locations where ruled lines intersect. To do.

[0005]

According to the ruled line forming method of the present invention, the step of storing the inputted ruled line data in a predetermined address of the video memory, the data which is subsequently inputted is the ruled line data and is inputted last time. If the ruled line data and the ruled line data exist in the same character unit, the step of determining whether or not the two ruled lines have different line lengths, and if the line values are different, the previously input ruled line data in character units from the video memory. To convert the ruled line data input this time into bit information, combine the two bit information, create a ruled line pattern based on the bit information, and call the video memory. It is provided with a step of re-inputting the address to which the call is applied.

[0006]

In this way, the capacity of the dictionary memory can be reduced, various ruled line patterns can be dealt with, and fine tabulation can be performed.

Embodiments of the present invention will be described below in detail with reference to the illustrated embodiments.

FIG. 2 is a block diagram of an apparatus showing a word processor to which the ruled line synthesis apparatus of the present invention is applied.
Reference numeral 1 in the figure is a central processing unit that controls the entire system based on the data input by the keyboard 2.
By inputting the reading data from the keyboard, the dictionary memory 3 in which kana-kanji conversion or symbols are stored is accessed, and a predetermined kanji or symbol pattern is output to the video RAM 4 (an example of video memory), and the CRT 5 or printer 6 is used. Are configured to be displayed and printed. Reference numeral 7 denotes a ruled line creating apparatus which is a characteristic part of the present invention, and reference numeral 8 in the drawing denotes a pattern recognition unit, which is the previously input ruled line data (hereinafter referred to as old ruled line) and the currently input ruled line data. When the new ruled line (hereinafter referred to as a new ruled line) is stored in the same character unit, that is, when the ruled line is entangled, this is detected, and whether the diameter of the new ruled line to be overlapped with the old ruled line is the same or not is detected. If it is determined that the line diameter is the same, the dictionary memory 3 is accessed to call a predetermined pattern, and this is stored in the address of the video RAM in which the old ruled line is stored. If the new and old ruled lines have different diameters, the old ruled line pattern is
The pattern of the ruled line is read in order from the wire diameter data table 1 in the direction of the arrow as shown in FIG.

[0009]

[Table 1] Blank Small diameter Large diameter 00 01 10 For small diameter in the horizontal direction in the same figure (b), 00, 01, 00, 01
In addition, (c) has a large vertical diameter of 10,00,10,0.
0, and in the half-lines of FIGS.
It is configured to be converted into bit information such as 0, 00, 00 and 00, 00, 00, 01 and output. A ruled line synthesizer 9 is configured to generate bit information obtained 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. A conversion table 10 is configured to generate a ruled line pattern corresponding to this based on the bit information from the ruled line synthesis control device 9. Reference numeral 11 denotes a temporary storage device for temporarily storing data in the calculation process of the ruled line synthesis control device.

Next, the operation of the apparatus configured as described above will be described with reference to FIG.
It will be described based on the flowchart shown in FIG.

When the ruled line data is input from the keyboard 2 to make a table, it is stored in the video RAM 4 via the central processing unit 1 and displayed on the display 5. In this way, when the ruled lines having a large diameter in the same direction, for example, the horizontal direction are drawn one after another (FIG. 5a), they do not intersect each other, and thus they are stored in the video ram 4 as they are (1). Next, if you draw a ruled line with a small diameter in the vertical direction,
b), intersects the old ruled line of large diameter (Fig. 5c). The pattern recognition unit 8 detects the intersection z of the different wire diameters (2), calls the old ruled line data existing in the same character unit from the video RAM 4 (3), and bit information (00, 10, 0).
It is converted into 0, 10) (4) and output to the temporary storage device 11 via the ruled line composition device 9 (5). On the other hand, for the new ruled line where the intersection occurs, bit information (01,
(00, 00, 00) to the ruled line synthesizer 9 (6),
Bit information of the old ruled line stored in the temporary storage device 11 and addition {(00, 10, 00, 10) + (01, 00,
00, 00)}, and bit information (01, 10, 00, 10) of a new ruled line pattern in which both ruled lines are combined is created (7). This bit information is input to the conversion table 10 and converted into the ruled line pattern (FIG. 5e) represented by this (8), and then input to the address of the video ram 4 that called the old ruled line (9). As a result, the ruled lines whose wire diameters in each direction are unified are stored in the video ram 4, and the CRT 5 and the printer 6 display and print the unified ruled lines in each direction. Needless to say, when the ruled lines having the same diameter are entangled, the ruled line pattern stored in the dictionary memory 3 is called (10) and is output to the address where the old ruled line of the video ram 4 is stored ( 9) Display and print.

In this embodiment, the case where two ruled lines having different wire diameters are orthogonal to each other has been described as an example. Needless to say, however, there is a case where ruled lines having the same wire diameter intersect or diagonally intersect. It is clear that can be similarly synthesized.

[0013]

As described above, according to the present invention,
Since the pattern of each ruled line in the character area where a plurality of ruled lines are entangled is converted into bit information and the pattern formed by these ruled lines is calculated, not only can the capacity of the dictionary memory be reduced. , It is possible to eliminate the unsightly appearance of the intersection processing and create a fine grained table.
