Abstract

PURPOSE:To automatically specify the write range of a ruled line by specifying an effective processing range of a table generated in advance, and limiting a cursor movement onto a surface frame for showing this processing range. CONSTITUTION:When a start point for drawing a ruled line is determined by a cursor key 1, the line kind is selected and the ruled line is drawn by setting an outer frame of the opposite side as an end point. When the start point is on the left row variable or the right row variable, a line of a text buffer 5 is read out to a one-line buffer 7 by a one-line data reading-out part 6. A ruled line writing part 9 writes this line in the buffer 7 by generating a horizontal ruled line in a position of a work buffer 10. Subsequently, the contents of the buffer 7 are written in the buffer 5 by a one-line data writing part 11, and a line in which a cursor exists is displayed. When the start point is on a line start variable or a line end variable, the line of the buffer 5 designated by the line counter variable is read out to the buffer 7 by the reading-out part 6. Next, a vertical ruled line is written by the designated line kind to a cursor position variable of the buffer 7, written in the buffer 5 by the writing part 11, and the line designated by the line counter variable is displayed on a display part 12.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial application field
The present invention relates to a document creation device that allows the writing of ruled lines on a formatted table.

(B) Prior Art In a conventional document creation device such as a word processor, when writing a table in a specific format using ruled lines, the cursor is moved to the position where the table is to be created using the cursor keys, and the ruled lines are After instructing to create a line, it is common to perform repeat input for each ruled line by holding down the key from the start point to the end point, or to specify the start and end points of the position to be drawn by moving the cursor, and then repeat the operation of connecting those points. (Word Pro Tool 1 from Sanyo Electric Co., Ltd.)
"Refer to the l-5WP-7700 operation manual).

(C) Problem to be Solved by the Invention However, in a table frame etc. in which the document text is already configured in a specific format, when new various ruled lines are drawn within the table frame, the ruled lines conforming to the format must be drawn. In this case, the cursor moves freely on the display screen, so the cursor may over-move when specifying the starting and ending points for writing a new ruled line. Therefore, the operator must move the cursor carefully, especially when the cursor moves near the end point.

The present invention is intended to solve the problem that writing new ruled lines into a table that has already been created is complicated as described above.

(d) Means for Solving the Problems The document creation device of the present invention is a document creation device that allows writing of ruled lines on a table configured in a specific format created in advance with ruled lines, and includes the above-described document creation device. In order to solve the problem, there is provided a means for specifying an effective processing range of a table including a ruled line specified by a cursor, and a means for limiting cursor movement to the table frame ruled line indicating the effective processing range based on the effective processing range. , and means for writing ruled lines based on the effective processing range.

(f) Operation As described above, by specifying the effective processing range of the table created in advance and limiting the cursor movement to the table frame indicating this processing range, the writing range of ruled lines is automatically specified.

(f) Example This will be explained in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of a document creation device of the present invention.

The keyboard 1 includes keys for instructing the creation of automatic ruled lines, keys for instructing to change the processing range of ruled line writing, character keys,
The keyboard 1 includes cursor keys and various instruction keys (not shown), such as keys for instructing conversion of reading input into kanji, keys for selecting the line type of ruled lines, and keys for instructing the end of processing. Various key operations input from the controller 2 are sent to the control unit 2. The control unit 2 controls data exchange between various parts of the apparatus, which will be described later, in accordance with input instructions. A line counter 3 counts the number of lines of text, and a cursor counter 4 counts the number of characters in one line, ie, the number of columns.

The text buffer 5 stores text such as characters, symbols, ruled lines, etc., and one line of data is read out from the text buffer 5 into the one line buffer 7 by the one line data reading section 6. The table frame analyzer 8 analyzes the text read into the one-line buffer 7, determines whether or not there is a complete table within the specified table frame, and determines whether the table is complete within the specified table frame, and determines the effective range of left column LX, right column RX, start line SY, and end line. Set EY. The ruled line writing unit 9 generates ruled line data of the designated line type (thin line, medium line, thick line, double line, broken line, etc.) to be drawn on the line stored in the single line buffer 7 in the work buffer 10 and writes it in the single line buffer 7. Write. The written text in the one-line buffer 7 is written to the text buffer 5 through the one-line data writing section 11, and then displayed on the display section 1 such as a CRT, liquid crystal, or plasma display.
Displayed as 2.

FIG. 2 is a flowchart showing the processing contents of the table frame analyzer, in which it is determined in step S1 whether or not the automatic ruled line instruction key has been pressed on the keyboard 1. If the instruction key has been pressed, the table frame analyzer 8 starts analyzing the specified seven formats of the designated table frame in step S2. That is, the table frame analyzer 8 determines whether the position specified by the cursor is on the ruled line in step S2, and if it is on the ruled line, sets the current cursor position in the variable CX in step S3. Next, in step S4, it is determined whether the component is included in the ruled line component at the current cursor position,
If it is not included, read the line data one line above the current line into the one line buffer (step S5), and also check that the variable CX position is on the ruled line that includes the vertical component.
Check in 6 steps. If a vertical component is included, S
Returning to step 4, the process returns to determining whether a horizontal ruled line component is included in this line data. Through this process, when a ruled line frame containing a horizontal ruled line component is searched for in step S4, a line number is set in variable SY as the analysis start line in step <57. FIG. 3-1 schematically shows a row number set by such a ruled line frame search.

If no ruled line including the component is found, the process ends.

After the analysis start row variable SY is set, in step S8, check the continuity of the horizontal ruled lines while counting the current column variable X toward the right from the start column variable CX shown in Figure 3-1. At the same time, whenever a ruled line having a lower component is detected, the position of the ruled line is set in the table variable R$TBL(*). In step S9, the position of the ruled line with the lower component in the left direction is similarly set in the table variable L$TBL (*) (3rd-
Figure 2).

Solution for the variable SY line After folding is completed, next, in the SIO step, read the line data one line below the current line into the one line buffer, and calculate the ruled line components in the right and left directions centering on the number of steps CX in the Sllll Stellar pull S18. Table variable R$T
The analysis is performed while referring to BL and table variable L$TBL. At this time, in step S17, a variable RX indicating a valid right column and a variable LX indicating a valid left column.
and update and set. Also, if the component ruled lines are continuous from variable LX to variable RX, the analysis end line is the table variable Y$TBL (*) and the analysis final line variable EY.
Set to . The state after such analysis is shown in FIG. 3-3.

This series of processing (S18 steps) is repeated until a line in which there is no ruled line data is reached, and the analysis is terminated.

As a result of the analysis by the table frame analyzer 8, the effective processing range is from the variable SY to the variable EY in the row direction, and from the variable LX to the variable RX in the column direction, that is, in this example, the row direction is 3 rows. to the 13th row, the column direction is determined from the 11th column to the 30th column, and in order to inform the operator of the range, virtual landmarks a, b, c, d is displayed and
The movement of the cursor is limited to the ruled line connecting the virtual landmarks a, b, c, and d.

Once the effective processing range of the table frame has been determined in this way, the operator waits for the keystrokes from the keyboard 1 to be pressed. Keys include cursor keys, line type keys, effective range change instruction keys, end keys, and the like.

FIG. 4 is a flowchart showing the contents of the change processing using the above-mentioned effective processing range indication key, and FIG. 5-1 and FIG.
Such a change process will be explained with reference to the schematic diagram in FIG. 5-1 shows an example in which the last line is changed from 13 to 10 in the state shown in FIG. 3-4, and FIG. 5-2 shows an example in which the last line is changed from 13 to 10.
4 shows an example in which the left column is changed from 11 columns to 20 columns in the state shown in FIG.

First, when the effective range change instruction key is pressed on the keyboard 1 in step S20, a process for changing the effective processing range determined by the table frame analyzer 8 is started. Virtual landmark C or d on the final row variable EY that continues to indicate the valid processing range
Set the cursor above. In step S21, the cursor position when the above instruction key is pressed is set to variables SY and E.
It is determined whether or not it is on the virtual landmark in the Y row. As a result of the determination, if it is determined that the cursor position is on the virtual landmark of the variable EY row, the process waits for the next keystroke in step S22. If the key manual is the up and down directions using the cursor keys,
While referring to the table variable Y$TBL (*) in step S23, the start row variable SYP that was initially set is
, end row variable EYP, and displays virtual landmarks C and d (in Figure 5-1, the appearance of the landmark C disappears due to the override of the cursor mark, and no changes are required for a and b). The mark is displayed even during processing).

If it is a left/right direction instruction using cursor key 1, in step S24, while referring to table variables L$TBL (*) and table variables R$TBL (*), first set left column variable LXP, right column variable RXP, virtual landmarks a and C are displayed, and the effective processing range is changed.

If the key input is another key, the process ends.

In this embodiment, the process of changing a single column or row has been described, but both may be changed by a single cursor movement.

The effective processing range is the table analysis in Figure 3 or the 5th table analysis as necessary.
Once the final decision has been made by the operator based on the diagram change process, the position to draw the ruled line is specified using the cursor key 1, the line type is selected, and the ruled line is written.

FIG. 6 is a flowchart showing the writing process of various ruled lines, and the process will be explained with reference to the schematic diagrams of FIGS. 7-1 and 7-2. In addition, Figures 7-1 and 7-
The effective processing range in both Figures 2 and 3 is the state shown in Figures 3-4 before the change processing.

First, a starting point for drawing a ruled line is determined using the cursor key 1. At this time, cursor key 1 is pressed only for the most external force frame of the specified table frame based on the determination of the effective processing range, that is, virtual landmark a,
You can only move on the ruled line connecting b, ' c, and d. The left and right keys move one half-width character, the up and down keys move one line, the left key subtracts 1 from the cursor position variable X, and the right key moves the cursor. Add 1 to the position variable X. Movement using the up and down keys does not change the value of the cursor position variable X.

Once the starting point for drawing the ruled line has been determined, the line type is selected in step S30 to draw the ruled line with the outer frame on the opposite side as the ending point. If the starting point X is on the variable LX or RX, the line of the text buffer 5 where the cursor is located is read into the one-line buffer 7 by the one-line data reading unit 6 in order to write a horizontal ruled line in step S31. The ruled line writing unit 9 generates a horizontal ruled line with a specified line type at a position in the work buffer 10 corresponding to between the variables LX-RX of the line read into the one-line buffer 7,
The generated horizontal ruled line is written into the one-line buffer 7. and,
The contents of the one-line buffer 7 are written into the text buffer 5 by the one-line data writing section 11. text buffer 5
Display the line where the cursor is located (Figure 7-1) and perform the next key operation. If the starting point
Step sets the variable SL to the row counter variable ML. The line of the text buffer 5 designated by the variable ML is read into the one-line buffer 7 by the one-line data reading unit 6. 1
Write a vertical ruled line in the cursor position variable X of the line buffer 7 using the specified line type in the same manner as the horizontal ruled line. The contents of the one-line buffer 7 are written into the text buffer 5 by the one-line data writing section 11.

The line specified by the variable ML in the text buffer 5 is displayed on the display section 12. Add 1 to the variable ML.

This process is continued until the variable ML exceeds the variable EL, and continuous vertical ruled lines are obtained (Figure 7-2), and the process is terminated.

Incidentally, such ruled lines can be written by repeatedly executing the flowchart of FIG. 6 while the virtual landmarks a, b, c', and d that define the effective processing range are displayed. can be applied.

In addition, in the present invention, S19 of the effective processing range analysis process
As mentioned above, the cursor movement is limited to the ruled line in the step, but in another embodiment, when the line type key for writing the ruled line is pressed, part of the restriction on the cursor movement is canceled and the restriction is removed. If the configuration is such that it is within the effective processing range, ruled lines can be drawn using conventional repeat input.

Even in this case, since the cursor cannot exceed the effective processing range, the operator does not have to pay any attention to positioning the end point, and there is almost no deterioration in operability.

(g) As described in detail of the invention, the document creation device of the present invention automatically specifies the writing range of ruled lines, so new ruled lines can be easily added to a predetermined range, and the document creation device of the present invention can be operated easily. You can improve your sexual performance.
