Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ruled line processing function of a word processor, a computer capable of creating a document, or the like.

2. Description of the Related Art Conventionally, when erasing ruled line data managed for each ruled line block, if erasing is performed without designating a ruled line erasing area, all ruled lines in a ruled line block with a cursor are erased. It is known that if the positions of the start point and the end point are designated by the cursor, the ruled lines of a rectangular area having the positions of these two points as diagonal lines are erased (for example, Japanese Patent Laid-Open Publication No. 6-86242)
0-134380, JP-A-63-36361).

[0002]

However, when erasing all the ruled lines of the rectangular area diagonally from the position of a certain starting point to the final line / column position, the cursor is used to specify the final line / column position. There was a problem that it had to move a considerable amount.

The present invention has been made in consideration of such circumstances, and in the process of erasing ruled lines in a document, by designating only the starting point with a cursor, the starting point position and the final line / column position are paired. Provided is a word processor capable of erasing all ruled lines of a rectangular area having a corner.

[0007]

In FIG. 1, the ruled line data input from the key input means 101 is stored in the input data storage means 102 and then stored in the ruled line storage means 103 separately into horizontal ruled line data and vertical ruled line data.

When the ruled line displayed on the screen of the display means 104 is erased, if there is an erase command when the starting point of the ruled line erasing area is designated by the key input means 102, the starting point position storage means 105 stores the start point. The line and column positions are stored, and the final position storage means 106 stores the size of the preliminary sheet and the maximum number of lines and the maximum number of columns that can be printed on the sheet.

Next, the horizontal ruled line erasing means 107 erases the horizontal ruled line data located at a digit higher than this position for each upper line from the start point position to the last line. The vertical ruled line erasing means 108 erases vertical ruled line data located in a row higher than this position for each upper digit from the position of the start point to the last digit.

Therefore, by designating only the starting point by the input means 101, it becomes possible to erase all the ruled lines in the rectangular area whose diagonal is the last row / column position from the starting point position.

FIG. 3 is a flow chart for explaining the processing contents in the ruled line deletion of the present invention. In FIG. 3, in the ruled line erasing process after the ruled lines are created, the control unit 3
Indicates the position of the ruled line erasing area by reading the position data from the designated position buffer 7 and waiting for the input of the erasing key of the keyboard 1.

When the operator designates the positions of the start point and the end point of the ruled line erasing area to be erased by the cursor of the keyboard 1 (step 31), the position data is stored in the designated position buffer 7. Next, when there is an erase key input (step 32), the control unit 3 releases the waiting state and performs the ruled line erase process in response to the erase command signal from the input buffer 2.

The control unit 3 determines whether the position data read from the designated position buffer 7 is a command for only the starting point (step 33). If only the starting point is designated, the process proceeds to the subroutine of step 34 of the present invention. A step 34 erases the ruled line data of a rectangular area diagonally corresponding to the designated start point and the last row / column position stored in advance (the subroutine of this step 34 will be described later in detail with reference to FIG. 4). To).

Next, the control unit 3 determines whether the area is specified by two points of the start point and the end point by the cursor or only the start point and the end point are not specified unless only the start point is specified (step 35). ..

If the area is designated by two points, the start point and the end point,
Proceeding to the subroutine of step 36, the control unit 3 reads out the ruled line data of the rectangular area whose diagonal is the position of two points of the start point and the end point from the ruled line compression buffer 6 and performs an erasing process.
Then, if neither the start point nor the end point is specified, the process proceeds to the subroutine of step 37, and the control unit 3 reads all the ruled line data in the ruled line block from the ruled line compression buffer 6 and performs the erase process.

FIG. 4 is a flowchart of the subroutine of step 34 in FIG. In this figure, the control unit 3
Is the line at the cursor (starting point) /
The column position and the line / column position of the final point are read (step 41).

Steps 42 to 47 are steps for erasing the horizontal ruled lines line by line. Step 42
Will preset the line number of the ruled line at the starting point designated by the cursor in the line counter. In step 43, the line number at the last line position and the line number in the line counter are compared. If the line number of the line counter does not exceed the line number of the last line position, the process proceeds to step 44.

In step 44, the horizontal ruled line compressed data of the row of the line counter is read from the ruled line compression buffer 6 and expanded into expanded data. As for the expanded horizontal ruled line expanded data, the horizontal ruled line expanded data located above the digit position of the cursor is deleted (step 45).

Next, the expanded horizontal ruled line data below the digit position of the cursor is compressed and stored in the ruled line compression buffer 6 (step 46). When the erasing process of the horizontal ruled line data for one line is completed, 1 is added to the line numerical value of the line counter (step 47) and the process returns to step 43. When the erasing of the horizontal ruled line data up to the last line is completed, the line numerical value of the line counter exceeds the line numerical value of the final line position, and the process proceeds from step 43 to step 48.

Steps 48 to 53 are steps for erasing the vertical ruled lines digit by digit. Step 48
Presets the number of digits of the ruled line at the starting point specified by the cursor in the digit counter. In step 49, the digit value of the last digit position and the digit value of the digit counter are compared. If the digit value of the digit counter does not exceed the digit value of the final digit value, the process proceeds to step 50. In step 50, the vertical ruled line compressed data of the digit of the digit counter is read from the ruled line compression buffer 6 and expanded into expanded data. As for the expanded vertical ruled line data, the vertical ruled line expanded data located above the digit position of the cursor is deleted (step 52).

Next, the vertical ruled line compression data at the lower position is compressed according to the line position of the cursor and stored in the ruled line compression buffer 6 (step 52). When the erasing process of the vertical ruled line data for one digit is completed, 1 is added to the digit value of the digit counter (step 53) and the process returns to step 49. When the deletion of the vertical ruled line data up to the final line is completed, the digit value of the digit counter exceeds the digit value of the final digit position, and thus all the ruled lines in the ruled line deletion area in which only the starting point is designated are erased.

In FIG. 5A, when a two-point area of a start point and an end point is designated by a cursor, a rectangular area diagonally designated by the two areas is an erasure target, and a shaded portion is a ruled line erasure target range. FIG. 5B shows ruled lines that are not to be erased in FIG. In FIGS. 5A and 5B, 50
Indicates a ruled line, 51 and 52 designate a cursor, and 53 indicates a ruled line erasing target range.

In FIG. 6 (a), when the cursor is used to specify the area only at the starting point, the rectangular area diagonally extending from the starting point to the last row / column position is the erasing target, and the shaded area is the ruled line erasing target range. .. FIG. 6B shows ruled lines that are not to be erased in FIG. In FIGS. 6A and 6B,
Reference numeral 60 is a ruled line, 61 is a cursor designation, 62 is a final line / column position, and 63 is a ruled line erasing target range.

FIG. 7 shows line / column positions on the document input screen,
The ruled line coordinate relationship is shown. As an example, a vertical ruled line at the 4th row and 10th digit and a horizontal ruled line at the 7th row and 10th column are shown in ruled line coordinates. The line / column position on the ruled line compression data in the ruled line compression buffer matches the ruled line coordinates.

FIG. 8 shows the overall structure of the ruled line compression buffer in which the ruled line compressed data is stored. Ruled line data for the entire document includes large blocks, medium blocks, small blocks,
It is managed as variable length ruled line compressed data layered into line segment data.

[0032]

By designating only the starting point with the cursor, it is possible to erase all the ruled lines in a rectangular area whose diagonal is the last row / column position from the starting point position. Therefore, if only the starting point is designated, the ruled line can be erased without moving the next designated cursor, which can improve the operability of the operator.
