FIG. 1 is a diagram showing an example in which character ruled lines are input into the effective print area according to this embodiment, and the processing of ruled line data will be explained based on this.

The effective print area is an area in which characters, numbers, etc. are input at positions indicated by lines indicating the horizontal direction and digits indicating the vertical direction.

Here, the character ruled lines are M from the Nth line to the N+2th line.
It is assumed that the information has been input from the digit to the M+2 digit.

The effective printing area is X in the left and right direction in units of dots.
If we take the Y axis in the vertical direction, the row position of the Nth row is the Y coordinate, Gn.The dot position, the row position of the N+1st row is Gn+1.
The dot positions are as follows: the N+2nd row is the position of the Gn+z dot, and the N+3rd row is the Gn+3 dot position.

Next, Gn+ which is the distance between the row positions of the Nth row and the N+1th row
The difference between 1 and Gn is LPn dot, the N+1st row and the N+2nd row
The difference between Gn+z and On+1, which is the distance between row positions, is LP
n+1 totu 1~, and the difference between Gn+a and Gnl, which is the distance between the row positions of the N+2 and N+3 rows, is L Pn+
Set it to 2.

Furthermore, the line spacing between the Nth and N+1st rows is LBn dots, the line spacing between the N+1st and N+2nd lines is LBn+t dots, and the line spacing between the N+2nd and N+3rd lines is L Bn+
2 Dots.

In addition, the digit position of the Nth row and Mth digit is Kn in the X coordinate, the m dot position, the M+1st digit is Kn, the m+1 dot position, M
The +2nd digit is the position of the Kn, m+2 dot, and the M+3rd digit is the position of the Kn, m+3 dot.

Next, calculate the distance between the Mth digit and M+1st digit position of the Nth row by C
Pn, m dot, distance between M+1st digit and M+2nd digit CPn, m+1 dot, M+2nd digit and M+3
Let the distance between the digit positions be CPn, m+z dots.

Then, set the character spacing between the Mth column and M+1st column of the Nth line to CB
n, m dot, character spacing between M+1st digit and M+2nd digit
Let CBn, m+1 dot, and the character spacing between the M+2nd and M+3rd digits be CBn, m+2 dots.

First, the character ruled line located in the Nth row and Mth column is a character ruled line that has two patterns: a horizontal ruled line Ω1 and a vertical ruled line L1. X coordinate 5Oc2 and v position of the starting point of vertical ruled line L1; [Syz
are at the same position, so when expressed with the number of dots above, S x1 = S x z = Kn, m+ (CPn,
m - CBn, m)/2S"/1 = St/2 = G
It becomes n+(LPn-LBn)/2.

And the end point will be as follows.

Regarding the horizontal ruled line Ω1 above, first, it is the midpoint a of the character interval with the adjacent M+1st digit, so its X coordinate is Eχ1+
”/If the coordinate is Eyl, E x 1 = S x
1 + CPn, m/2E”/1 ==Sy1.

Next, regarding the vertical ruled line L1, first, since it is the midpoint of the line spacing between the Nth line and the N+1th line, its X coordinate is Eyl.
, t/coordinate is E'/2, then EOc2 = Sz2 Eyz = Syz + LPn /2.

Next, the character ruled line located at the M+1st column of the Nth row is the horizontal ruled line Q
Since the starting point is the midpoint a of the character interval with the M-th digit, it is the same as the position indicated by the above-mentioned X coordinate E OC1r y coordinate E''/1.

Therefore, the end point of the M-th horizontal ruled line Q1 and the starting point of the M+1-th horizontal ruled line f12 match, and since both ruled lines are horizontal ruled lines with the same pattern, if they have the same color, they are treated as connected ruled lines, and their end points are The end point of the horizontal ruled line Q2 at the M+1 digit is the midpoint C between the character spacing between the M+1 digit and the M+2 digit.

That is, the end point of the M-th horizontal ruled line Q1 is updated to the end point C of the M+1-th horizontal ruled line C2.

Therefore, the updated X and V coordinates of the end point are Ez1=Kn, m+1 +CPn, m+1-CBn, m
+1/2E”/1: St/1.

In this way, by updating the end point position one after another, M
Since the horizontal ruled line of the Nth row ends at the +2nd digit, the ending point is set as the ending point of the horizontal ruled line Q3 to be output to the Nth row.

Then, the X coordinate of the end point is the midpoint of the character width of the M+2nd digit character ruled line, so E x1 = Kn, mHz + (CPn, mHz -
CBn, mHz)/2Ey1=SV1.

Here, since the vertical ruled line L4 extends downward from the above end point as the starting point, the X coordinate of the starting point is Sχ3°, and the X coordinate is S'
/3, then Sχ3=EχI St/3 :St/1, and the end point is the midpoint d of the line spacing between the Nth row and the N+1th row, so its X coordinate is Eχ31 and its V coordinate is E”/
3, Ex3=Sx3Ey3=Gn+LPn-LBn/2.

Next, when moving to the N+1st line, the Mth character ruled line is the vertical ruled line L
It has only 2 patterns, and its starting points are the Nth row and the N+1th row.
The coordinates of the end point of the vertical ruled line L1 are Exz = Kn+1, m+(CPn+1, m-CB
n+1, m)/2Eyz = Gn+LPn-LBn/
Matches 2.

Here, since the patterns of both vertical ruled lines are the same, if the colors are the same, they are treated as connected ruled lines, and the end point of the vertical ruled line L1 is updated to the end point of the vertical ruled line L2 in the N+1st row and M column.

Its position is the midpoint e of the line spacing between the N+2 and N+1 rows, and its coordinates are E $2 = S r2 E q 2 : Gnat + LPn+1- LBn
It becomes +1/2.

Next, since the M+1st column is a blank character, when proceeding to the next M+2 column, this character line has only the pattern of vertical ruled line L5, and the starting point is the midpoint d of the line spacing between the Nth line and the N+1th line. Therefore, the X coordinate of that position is Sχ3+V coordinate is S! /9
Then, S x3 = S xz S y 3 = Gn+ LPn - LBn/2.

This starting point and the end point of the vertical ruled line L4 match, and since both ruled lines have the same pattern, if they have the same color, they are treated as connected ruled lines and their end points are updated.

In other words, the end points of the vertical ruled line L4 are the N+1st line and the N+2nd line.
It becomes the midpoint f of the line spacing of the row, and its X coordinate is Eχ9r
If the V coordinate is E”/3, E Oc3 = S x
3 E(/3 =Gn+x +LPn+1 -LBn+
It is 1/2.

Then, moving to the N+2th line, the M-th character ruled line is a character ruled line that has both patterns of vertical ruled line L3 and horizontal ruled line ρ4,
The starting point of the vertical ruled line L3 and the end point of the vertical ruled line L3 of the N+1 row match, and if they are the same color, they are connected, so from the Nth row to the N+
This is the final end point of the vertical ruled line that passes through the Mth column of the second line, so
The end point of the vertical ruled line L1 is updated to this position.

The end point of this vertical ruled line L3 is the midpoint of the character width in the N+2nd row and M column, so the X and V coordinates of that position are EOc2 =
Sxz E q 2 = Gn+z + (LPn+z −LBn
+2)/2.

Here, since the horizontal ruled line Q4 starts from the end point of the vertical ruled line L3 in the N+2nd row and M column, the X coordinate of the starting point is S Oc
4 + t/If the coordinate is S”/4, Sr4 = Sz
2Sv4=Et/2.

Then, set the χ coordinate of the end point to Eχ4. ? /Coordinates are E”/
4, Ex4=Kn, m+CPn, m-CBn, m/2Et
/4=Sy4.

Thereafter, by updating the position of the end point while checking whether adjacent ruled lines are connected in the same manner, data on the starting point and end point for a total of four ruled lines can be obtained.

FIG. 5 shows the flow of the process for updating the ruled line data.

This routine starts when a character ruled line is input, and checks whether there is a ruled line pattern on the top or left side.

Then, if there is, it is checked whether there is a next connected ruled line pattern, and if there is, the coordinates indicating the end point position of the ruled line data are updated according to the method described above.

If any of the above checks is No, a new ruled line is started, so new ruled line data is created and the starting point and ending point are determined.

Based on the data of the starting point and ending point of each ruled line obtained in this way,
Manage character ruled lines as vector ruled lines.

The following table shows an example of the ruled line data management table.

[Ruled line data management table]

This table has 13 rows of storage columns, the first row is a "page number" column that stores the number of pages that have ruled lines, and the second row is a "page number" column that stores the column number within this page that has ruled lines. The column number” column, the third line is the “direction” column that indicates the direction of the ruled line,
If it is a horizontal ruled line, "0" is stored, and if it is a vertical ruled line, "1" is stored.

The fourth line is a ``line type'' column that stores the line pattern of the type of ruled line, such as a solid line with two dotted lines, and the fifth line is a ``color J'' column that stores information indicating the color of the ruled line.

Then, from the sixth line to the ninth line, the above-mentioned starting and ending positions of the ruled lines are stored as coordinate positions of the effective print area in units of dot numbers.

That is, the 6th line stores the χ coordinate of the starting point, the 7th line stores the y coordinate of the starting point, the 8th line stores the χ coordinate of the ending point, and the 8th line stores the V coordinate of the ending point.

From the 10th line to the 13th line, the line position and column position corresponding to the starting point and ending point of this ruled line are stored.

In other words, set the column position where the ruled line starts in the 10th line to the 1st column.
The line position is stored in the first line, the column position where the ruled line ends in the 12th line, and the line position in the 13th line.

These ruled line management data are stored on a floppy disk or the like by the external storage device 5 at the same time as the created document is registered.

Note that the format of this management table may be formed in units of rows or columns, depending on the system implementing the present invention.

〔Effect of the invention〕

According to the character ruled line processing method according to the present invention, since character ruled lines are stored as vector ruled lines, data can be sent quickly even to a printing device capable of high-speed printing such as a laser printer.

Furthermore, when updating a document, a document screen that initially displays a document read from an external storage device can be displayed at high speed, and when the document screen is scrolled, ruled lines can be displayed at high speed.
