Description

The present invention relates to a ruled line adding / creating apparatus which permits writing of ruled lines in a table which is formed in advance and has a specific format and is formed of ruled lines.

(B) Conventional technology In a conventional document creation device such as a word processor,
To write a table in a specific format using a ruled line, move the cursor to the position where the table is to be created using the cursor keys, specify the ruled line creation, and then press the key from the start point to the end point. It is common practice to perform each operation, or to repeatedly specify the starting point and the ending point of the position to be pulled by moving the cursor, and perform an operation of connecting the points (a word processor manufactured by Sanyo Electric Co., Ltd.).
Refer to the SWP-7700 operation manual).

(C) Problems to be Solved by the Invention However, in the case of a table frame or the like that is already configured in a specific format in the document text, when various new ruled lines are drawn in the table frame, a ruled line conforming to the format is drawn. In many cases, the cursor moves freely on the display screen, so that when specifying the start point and end point of writing a new ruled line, the cursor may move over. Therefore, the operator must carefully perform the moving operation especially when the cursor moves near the end point.

An object of the present invention is to solve the problem that the operation of writing a new ruled line in a table that has already been created is complicated as described above.

(D) Means for Solving the Problems The present invention relates to a ruled line adding / creating apparatus which allows writing of a new ruled line in a table formed in a specific format which has been previously formed by ruled lines. Display means for displaying a ruled line including a table already completed and a cursor; specifying means for specifying a table including a ruled line designated by the cursor of the display means as an effective processing range of a table to which a new ruled line is to be written; Control means for displaying the effective processing range of the table specified by the means on the display means, and movement of the cursor for designating the position where a new ruled line is to be written, and a table indicating the effective processing range of the specified table. A cursor movement limiting means for limiting the position on the frame ruled line; a position designating means for designating a position where a new ruled line is to be written by the limited cursor movement; Ruled line determining means for determining whether a ruled line to be written is a vertical ruled line or a horizontal ruled line based on the cursor position, and writing means for writing the determined ruled line without exceeding the effective processing range based on the designated cursor position. , Is provided.

(E) Function When adding a new ruled line to the table created in advance as described above, the table including the ruled line specified by the cursor by the specifying means is specified as the effective processing range of the table in which the new ruled line is to be written. By automatically specifying the table to be written by the control means and displaying the effective processing range of the table specified by the control means on the display means, the operator can specify the table to which a new ruled line to be written by the display is displayed. It can be clearly confirmed.

Further, the movement for designating the position where a new ruled line is to be written by the cursor movement limiting means is limited to the table frame ruled line indicating the effective processing range of the specified table. The position to which a new ruled line is to be written by movement is specified, and whether the ruled line to be written is a vertical ruled line or a horizontal ruled line is determined based on the cursor position specified by the ruled line determining means. , The ruled line can be written without exceeding the effective processing range, so that the ruled line writing operation is simplified and a new ruled line can be easily added to a desired range.

(F) Embodiment Hereinafter, an embodiment of the ruled line additional creation device of the present invention will be described in detail with reference to the drawings.

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

The keyboard 1 includes a key for instructing creation of an automatic ruled line, a key for instructing a change of a processing range of ruled line writing, a character key, a cursor key, and a key for instructing conversion of kanji to reading input (not shown). Various instruction keys such as a key for selecting the line type of the ruled line and a key for instructing the end of the processing are provided. Various key operations input from the keyboard 1 are sent to the control unit 2. The control unit 2 controls data transmission / reception of each unit of the apparatus described later according to the input command. The line counter 3 counts the number of lines of text, and the cursor counter 4 counts the number of characters in one line, that is, the number of columns.

The text buffer 5 stores text such as characters, symbols, and ruled lines. One line of data is read from the text buffer 5 to the one-line buffer 7 by the one-line data reading unit 6. The table frame analyzer 8 analyzes the text read into the one-line buffer 7 and determines whether or not the table is a complete table within the specified table frame. The valid range left column LX, right column RX, start line
Set SY, end line EY. The ruled line writing unit 9 generates ruled line data of a designated line type (thin line, medium line, thick line, double line, broken line, etc.) to be drawn on the line stored in the one-line buffer 7 in the work buffer 10 and stores it in the one-line buffer 7. Write. The written text in the one-line buffer 7 is written from the one-line data writing unit 11 to the text buffer 5 and displayed on the display unit 12 such as a CRT, a liquid crystal display, or a plasma display.

FIG. 2 is a flowchart showing the processing contents of the table frame analyzer. In step S1, it is determined whether or not the automatic ruled line designation key on the keyboard 1 has been pressed. If the instruction key is pressed, the analysis of the specified format of the designated table frame is started by the table frame analyzer 8 in step S2. That is, the table frame analyzer 8 determines whether or not the position specified by the cursor is on the ruled line in step S2.
In step S3, the current cursor position is set in the variable CX. Next, in step S4, it is determined whether or not a horizontal component is included in the ruled line component at the current cursor position. If not, row data one line above the current line is read into a one-line buffer (step S5). In step S6, it is confirmed that the variable CX position is on the ruled line including the vertical component. If a vertical component is included, the process returns to step S4, and returns to the determination of whether or not the horizontal ruled line component is included in the row data. When the ruled line frame including the horizontal ruled line component is searched in step S4 by this processing, the line number is set to the variable SY as the analysis start line in the subsequent step S7. FIG. 3-1 schematically shows a line number set by such a ruled line frame search.

If no ruled line containing a horizontal component is found, the process ends.

Once the analysis start line variable SY is set, in step S8,
While counting the current column variable X rightward from the start column variable CX shown in FIG.
Each time a ruled line having a lower component is detected while checking the continuity of the horizontal ruled line, the position of the ruled line is set to a table variable R @ TBL (*) each time. In step S9, similarly, the position of the ruled line having the lower component in the left direction is set in the table variable L @ TBL (*) (FIG. 3-2).

After the analysis of the variable SY line is completed, the line data one line below the current line is read into the one line buffer in step S10, and the rightward and leftward ruled line components centering on the variable CX are read in steps S11 to S18. The analysis is performed with reference to the table variable R @ TBL and the table variable L @ TBL. At this time, the variable RX indicating the right column effective in step S17
And a variable LX indicating a valid leftward column are updated and set. If the horizontal component rule is continuous from the variable LX to the variable RX, the analysis end row is set to the table variable Y 変 数 TBL
(*) And set to the analysis last line variable EY. The state after the completion of such analysis is shown in FIG. 3-3.

This series of processing (steps S11 to S18) is repeated, and if a line without ruled line data is reached, 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. To 13 rows, column (column) direction from 11 columns
In step S19, virtual markers a, b, c, and d are displayed at the four corners to notify the operator of the range in step S19, and the cursor is moved by the virtual marker. It is limited to the ruled line connecting the marks a, b, c and d.

When the effective processing range of the table frame is determined in this manner, the key input from the keyboard 1 is waited. The key input includes a cursor key, a line type key, an effective range change instruction key, an end key, and the like.

FIG. 4 is a flow chart showing the contents of the change processing by the valid processing range instruction key.
The change process will be described with reference to the schematic diagram of FIG.
FIG. 5A shows an embodiment in which the last row is changed from 13 rows to 10 rows from the state shown in FIG. 3D, and FIG.
An example is shown in which the left column is changed from 11 columns to 20 columns from the state shown in the figure.

First, when the effective range change instruction key is pressed by the keyboard 1 in step S20, the process of changing the effective processing range determined by the table frame analyzer 8 is started. A virtual landmark c or d on the last line variable EY that continuously indicates the valid processing range
Set the cursor on top. In step S21, it is determined whether or not the cursor position at the time when the instruction key is pressed is on the virtual mark on the variable SY, EY line. If it is determined that the cursor position is on the virtual landmark of the variable EY line, the next key input is performed in step S22. Key input is
If the direction is the up / down direction using the cursor keys, the virtual landmark c is moved in a range not exceeding the first set start line variable SYP and end line variable EYP while referring to the table variable Y @ TBL (*) in step S23. (In FIG. 5-1, the mark of c is apparently erased due to the overwriting of the cursor mark, and the marks of a and b which do not need to be changed are displayed during the processing). If the instruction is the left / right direction using the cursor key 1, the table variable L ＄ TBL is set in step S24.
(*), While referring to the table variable R @ TBL (*),
First set left column variable LXP, right column variable RXP,
And the 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, a description has been given of a single column or row changing process. However, both may be changed by a single cursor movement.

When the effective processing range is finally determined by the operator based on the table analysis in FIG. 3 or the change processing in FIG. 5 as necessary, the position to draw the ruled line is designated by the cursor key 1, the line type is selected, and the ruled line is drawn. Write.

FIG. 6 is a flowchart showing such various ruled line writing processing. The processing will be described with reference to the schematic diagrams of FIGS. 7-1 and 7-2. FIG. 7-1 and FIG.
The effective processing range in both FIG. 2 and FIG. 3 is the state in FIG. 3-4 before the change processing.

First, a starting point for drawing a ruled line is determined by the cursor key 1. At this time, the cursor key 1 can be moved only in the outermost frame of the table frame specified based on the determination of the effective processing range, that is, only on the ruled line frame connecting the virtual landmarks a, b, c, and d. One half-width character moves up and down one line, the left key decrements the cursor position variable X by one, and the right key adds one to the cursor position variable X. Movement by the up / down keys does not change the value of the cursor position variable X.

When the starting point for drawing the ruled line is determined, the line type is selected in step S30, and the ruled line is drawn with the outer frame on the opposite side as the end point. If the starting point X is on the variable LX or RX, the line in the text buffer 5 where the cursor is located is read out to the one-line buffer 7 by the one-line data reading unit 6 to write a horizontal ruled line in step S31. The ruled line writing unit 9 includes a work buffer corresponding to the variables LX to RX of the row read to the one-row buffer 7.
At step 10, a horizontal ruled line is generated with a designated line type, and the generated horizontal ruled line is written to the one-line buffer 7. Then, the contents of the one-line buffer 7 are written into the text buffer 5 by the one-line data writing unit 11. The cursor line in the text buffer 5 is displayed (FIG. 7-1), and the next key input is performed.
If the starting point X is not on the variables LX and RX but on the row variable SY or EY, the variable SL is set to the row counter variable ML in step S23 to write a vertical ruled line. The line of the text buffer 5 specified by the variable ML is read out to the one-line buffer 7 by the one-line data reading unit 6. A vertical ruled line is written in the cursor position variable X of the one-line buffer 7 in the same manner as the horizontal ruled line with the designated line type. The contents of the one-line buffer 7 are written to the text buffer 5 by the one-line data writing unit 11. The line specified by the variable ML of the text buffer 5 is displayed on the display unit 12. Variable ML
Plus one. This process is performed until the variable ML exceeds the variable EL, a continuous vertical ruled line is obtained (FIG. 7-2), and the process ends.

The writing of such ruled lines can be performed by repeatedly executing the flowchart of FIG. 6 while the virtual marks a, b, c, and d defining the effective processing range are displayed. Can be applied.

In the present invention, S19 of the effective processing range analysis processing
In the step, the cursor movement was limited to the ruled line as described above. However, as another embodiment, when the line type key for writing the ruled line is pressed, the limitation of the cursor movement is partially released, and the limitation is removed. With such a configuration as to be within the effective processing range, ruled lines can be drawn by conventional repeat input. Even in this case, since the cursor cannot exceed the valid processing range, the operator does not pay any attention to the positioning of the end point, and the operability is hardly reduced.

(G) Effects of the Invention As is clear from the above description, the writing range of the ruled line is automatically specified for the created ruled line, the range can be confirmed on the display means, and a new ruled line of the cursor is written. The movement for designating the position to be specified is limited to the table frame ruled line indicating the effective processing range of the specified table, and writing is performed by specifying the position where a new ruled line is to be written by the limited cursor movement. It is automatically determined whether the desired ruled line is a vertical ruled line or a horizontal ruled line, and the ruled line is written based on the specified cursor position without exceeding the effective processing range, so that the ruled line writing operation is simplified and a new ruled line can be created. It can be easily added to a desired range, and operability can be improved.
