DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

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

[0002]

However, when erasing all ruled lines in a rectangular area having the last line / column position as a diagonal from a certain starting point, the cursor is used to designate the last line / column position. Has to be moved by a considerable amount.

The present invention has been made in view of such circumstances. In a process of erasing a ruled line in a document, by specifying only a start point with a cursor, the start point position and the last line / column position can be paired. Provided is a word processor capable of erasing all ruled lines in a rectangular area as a corner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on embodiments shown in the drawings. It should be noted that the present invention is not limited by this. FIG. 2 is a block diagram showing a configuration of an embodiment in which the present invention is applied to a word processor.

In FIG. 1, reference numeral 1 denotes a keyboard provided with a kana character key, a numerical key, a conversion key, an erasure key, a function key, and the like. Is input.

2 is an input buffer comprising a RAM,
Ruled line data, position data,
An erasure command and text data are input. Reference numeral 2 denotes an input buffer composed of a RAM, which temporarily stores ruled line data, position data, and text data input from the keyboard 1.

Reference numeral 3 denotes a control unit composed of a CPU, which converts document data stored in the document buffer 5 into kana-kanji characters in accordance with a command from the keyboard 1, and stores horizontal ruled line data and vertical ruled line data stored in the ruled line compression buffer 6. , And erases the ruled line in the ruled line erase area from the cursor start point position and end point position data stored in the designated position buffer 7.

Reference numeral 4 denotes a program memory composed of a ROM, in which a program for controlling the entire system in cooperation with the control unit 3 is written. 5 is the sentence buffer. Reference numeral 6 denotes the ruled line compression buffer. 7 is the designated position buffer. 5, 6, and 7 are all composed of RAM.

Reference numeral 8 denotes a display unit including a CRT display device and an LCD display device, and displays a series of operations. An output unit 9 outputs a series of operation results, such as a thermal transfer printer or an ink jet printer.

FIG. 3 is a flow chart for explaining the contents of processing in the ruled line erasing of the present invention. In FIG. 3, in the ruled line erasing process after the ruled line is created, the control unit 3
Indicates that the position of the ruled line erasure area is read from the designated position buffer 7 to read the position data, and waits for the input of the erase key of the keyboard 1.

When the operator designates the start and end positions of the ruled line erasure 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 cancels the waiting state and performs the ruled line erasing process according to the erase command signal of 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 start point is specified, the process proceeds to the subroutine of step 34 of the present invention. Step 34 erases the ruled line data of the rectangular area having the designated starting point and the previously stored last row / column position as a diagonal (the subroutine of this step 34 will be described later in detail with reference to FIG. 4). Do).

Next, if it is not the case that only the start point is specified, the control unit 3 determines whether the area is specified by the two points of the start point and the end point by the cursor, or whether neither the start point nor the end point is specified (step 35). .

If the area is specified by two points, a start point and an end point,
Proceeding to a subroutine of step 36, the control section 3 reads ruled line data of a rectangular area having a diagonal of the positions of the starting point and the ending point from the ruled line compression buffer 6 and performs an erasing process.
If neither the start point nor the end point is specified, the process proceeds to a subroutine of step 37, in which the control unit 3 reads out all the ruled line data in the ruled line block from the ruled line compression buffer 6 and performs an erasing process.

FIG. 4 is a flowchart of a subroutine of step 34 in FIG. In this figure, the control unit 3
Is specified by the designated position buffer 7 at the line of the cursor (start point).
The digit position and the row / column position of the last point are read (step 41).

Steps 42 to 47 are steps for erasing the horizontal ruled lines line by line. Step 42
Presets the line value of the ruled line at the start point specified by the cursor in the line counter. In step 43, the row value of the last row position is compared with the row value of the row counter. If the row value of the row counter does not exceed the row value at the last row position, the process proceeds to step 44.

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

Next, the horizontal ruled line development data lower than the digit position of the cursor is compressed and stored in the ruled line compression buffer 6 (step 46). When the erasure processing of the horizontal ruled line data for one line is completed, 1 is added to the line value of the line counter (step 47), and the process returns to step 43. When the erasure of the horizontal ruled line data up to the last line is completed, the line value of the line counter exceeds the line value at the last line position, and the process proceeds from step 43 to step 48.

Steps 48 to 53 are steps for erasing the vertical ruled lines one digit at a time. 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 is compared with the digit value of the digit counter. If the digit value of the digit counter does not exceed the digit value of the last 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 is expanded into expanded data. The developed vertical ruled line data deletes the vertical ruled line developed data higher than the digit position of the cursor (step 52).

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

FIG. 5A shows that, when two areas of the start point and the end point are designated by the cursor, a rectangular area having two areas designated as diagonals is to be erased, and a hatched portion is a ruled line erasure target range. FIG. 5B shows ruled lines not to be erased in FIG. 5A and 5B, 50
Indicates a ruled line, 51 and 52 indicate cursor designation, and 53 indicates a ruled line erasure target range.

FIG. 6A shows that, when an area of only the start point is designated by the cursor, a rectangular area having the last line / column position as a diagonal from the start point is to be erased, and a hatched area is a ruled line erasure target area. . FIG. 6B shows ruled lines not to be erased in FIG. In FIGS. 6A and 6B,
60 indicates a ruled line, 61 indicates a cursor designation, 62 indicates the last line / column position, and 63 indicates a ruled line erasure target range.

FIG. 7 shows the line / column position on the document input screen,
The ruled line coordinate relationship is shown. As an example, a vertical ruled line in the fourth row and tenth digit and a horizontal ruled line in the seventh row and tenth digit in ruled line coordinates are shown. 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 a ruled line compression buffer in which ruled line compression data is stored. The ruled line data for one entire document consists of large blocks, medium blocks, small blocks,
It is managed as compressed data of variable length ruled lines hierarchized into line segment data.

[0032]

As described above, according to the present invention, the starting point
If the input instruction is only for the position, the starting point and the last line / column position
Delete the ruled lines in the rectangular area that is the diagonal, and set the start point and end point
If it is a position input instruction, the positions of the start point and the end point are diagonal
Erase the ruled lines in the rectangular area to be set, and start and end points
If none of these are input instructions, all stored ruled lines
And how to input the start and end points.
Thus, three types of ruled line erasure ranges can be designated. Therefore, the operator can arbitrarily change the range in which the ruled lines are collectively erased as necessary, so that the operability of editing a document including the ruled lines is further improved.
