Description

The present invention relates to a word processor having an extended table frame.

(B) Conventional technology In a word processor in which a table frame divided by ruled lines is formed and characters are input into the table frame, it is assumed that no characters will be input beyond the size of the already divided table frame. At this time, it is desirable that the table frame be automatically extended with the input of characters.

The prior art disclosed in Japanese Patent Application Laid-Open No. 57-59229 discloses that a frame is formed by an indent mark that divides a block editing area, and if characters are input in the state of the frame formed by the indent mark, block editing by the indent mark is performed. By the processing, automatic extension is performed, and after the character is input, the characters larger than the size of the table frame (in this state, the frame with the indent mark) that has been preliminarily divided by replacing the indent mark with the ruled line are allowed. .

However, in this prior art, when a character is input again with the ruled line displayed, the processing unit does not recognize that the table frame of the ruled line section is the block edit area. The frame does not extend automatically. Therefore,
It is necessary to return the table frame of the ruled line section to the indent mark again and to input characters in the framework of the indent mark, resulting in poor operability.

(C) Problem to be Solved by the Invention The present invention solves the problem that the operability is poor because the table frame is not automatically extended when the characters are excessively input into the table frame of the ruled line section as described above. It is an issue.

(D) Means for Solving the Problem The present invention is a word processor having an input means (1), an output means (4,5), and a control storage means (6), the control storage means (6) Is for arranging character / symbol strings in a table frame divided by ruled lines, and when the cursor position indicating the input position moves on the ruled line that divides the table frame, If it is determined that the code is a ruled line code indicating the lower right corner of the table frame, the table frame extension processing inserts a space line with the same ruled lines as the table frame at the left and right ends into the table frame. Is extended downward.

(E) Action As described above, it is determined based on the cursor position whether or not the ruled line indicates the lower right corner of the table, and when it is the lower right corner, the same ruled line as the current line is added to the line next to the cursor position. The table frame ruled lines can be automatically extended by copying and inserting.

(F) Example Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of a Japanese word processor using the present invention, and FIG. 2 is an array diagram of an all-character array type pen-touch type keyboard.

In FIG. 1, reference numeral 1 is a keyboard as an input means.

2 is a control unit including a CPU.

Reference numeral 3 denotes various memories for storing a control program, storing an input document, and storing a dictionary.

Reference numeral 4 is a CRT as an output means.

Reference numeral 5 is a printer as an output means.

Reference numeral 6 is a control storage means. The control storage means 6 comprises a control unit 2 and a memory 3.

The text input from the keyboard 1 is stored in the text memory constituting the memory 3 by the function of the control unit 2, and is displayed on the CRT 4 along with it.

Then, this sentence is printed by the printer 5 by giving a print command, and stored in a floppy disk provided as an external memory of the memory 3 so that it can be used for subsequent printing.

Thus, this word processor has the following block editing function.

To explain this function, first, if you want to secure the photo sticking space on the right side as shown in FIG. 3, write the diamond type indentation mark 61 in advance on the left side of the space by touching the "indent" key 11. This indent mark 61 and the left margin mark
The area sandwiched by 62 and is edited as one block (when inputting, a line feed is made when the cursor comes to the indent mark. When deleting / subscribing, this is done within this block).

The indentation mark does not contribute to printing. In order to avoid the trouble of writing a lot of indentation marks 61, the indentation mark 61 is written in the upper line, so that the indentation mark is automatically written to the position immediately below each line break in the lower line. Is done.

Although this embodiment has a table forming function, as shown in FIG. 4, the ruled line 63 is seen in the same manner as the indent mark, and the block editing as described above inside the table and the margin mark 62 at the outside of the table are performed. It is possible to edit blocks in the area sandwiched between and the ruled line. Then, as shown in FIG. 5, when the table is in an incomplete state, that is, when the horizontal line at the bottom of the table is not drawn, the text input is the right end of the line corresponding to the lower terminal of the vertical line 64 of the table. The vertical line is automatically extended downward when it reaches the full width, and the block editing area of this table is enlarged.

The enlargement function is the same for the area sandwiched between the margin mark 62 and the vertical line 64. Such an enlarging function is exactly the same as the enlarging function of the block edit area by automatically writing the indent mark on the next line.

Thus, the expansion of the block editing area in the table as described above can be achieved by inputting a sentence in this table even if the table is closed in advance by a horizontal line as shown in FIG. The horizontal lines are executed one line at a time.

On the other hand, as shown in FIG. 6, when the lower end of the table is completed with horizontal lines closed, the left margin mark 62
When text is entered in the block edit area between the table and the vertical line 65 of the table and the characters are filled to the right edge of the last line (same line as the horizontal line) of the table, the table is not extended and If the indentation mark 61 is displayed in its extension position instead of the ruled line and the text input continues after that, the block editing area is expanded by adding the indentation mark in the same way as described above. .

In order to execute the block edit area expanding function of the present embodiment as described above, it is necessary to specify the position in the table from the ruled line pattern. Therefore, first, the tabulation function in this embodiment will be briefly described.

The operation procedure of ruled line drawing is as follows. That is, the cursor is moved to a position on the CRT4 screen where the ruled line should start, and the "ruled line" key 12 is touched. In response to this, the control unit 2 executes a predetermined program to determine the type of ruled line (thin line, thick line, 2
A pattern for guiding this is displayed in order to instruct the selection of the heavy line and the broken line). By operating the ten-key corresponding to the desired ruled line, the cross pattern of the corresponding line type is displayed at the cursor position, and by touching the cursor repeat key 13 in the direction of the desired ruled line, the ruled line is drawn in that direction. Go.

A code for displaying or printing such ruled lines is a 16-bit code, and a pattern for displaying the ruled lines or a font for printing the ruled lines is assigned to each. Of the 16-bit data, the upper 8 bits indicate a ruled line code, and the lower 8 bits specify the font pattern.

In this embodiment, the printing font is 32x32, and the CRT
Each screen display font is composed of a 24 x 24 dot matrix, but in the case of a ruled line font, a very limited part of these matrices is used. That is, as schematically shown in FIG. 7A, a region 71 showing a ruled line portion extending upward from the center, a region 72 showing a ruled line portion extending downward, a region 73 showing a ruled line portion extending leftward and a rightward direction. This is the area 74 indicating the extended ruled line portion, but the ruled line information (none, thin line, double line, thick line) of each area is allocated to each 2 bits from the upper side of the lower 8 bits of the upper 16-bit code. There is.

And without ruled line: 00, thin line: 01, double line: 10, thick line: 11, this means that the lower 8 bits 00000000 has no ruled line in that part, and 00000101 is as shown in Fig. 7 (b). A horizontal thin line that extends over the entire width of the font, 00000001 is a horizontal thin line that appears only in the right half of the font as shown in Fig. 7 (c) (broken lines are drawn as a continuation of this), 11111111 is shown in Fig. 7 (d). As shown in the figure, the bold cross-shaped portion, 10100000, consists of double lines extending in the entire vertical direction of the font as shown in FIG.

Therefore, the displayed content corresponding to the code written in the text memory must be a ruled line (upper 8
(Depending on bits) and type of ruled line (depending on lower 8 bits)
Will be identified.

That is, when the lower 8 bits of the write data in the text memory which is examined in association with the cursor position is 01000001, it has an L-shaped pattern as shown in FIG. If it is determined that it corresponds to the left end of the lower terminal (lower left corner), and if the lower 8 bits are 01000100, it has an inverted L-shaped pattern as shown in FIG. Bottom terminal right edge (bottom right corner)
It is determined to correspond to.

Now, the control unit 2 for enlarging the block editing as described above.
The process will be described with reference to the flowchart of FIG.

The character key 14 is touched to write a character in the text memory, and the CRT 4 displays the character, but the cursor is moved each time one character is input. As shown in FIG. 9 (a), when the characters are being entered between the left margin mark 62 and the indent mark 61 located on the right side of the margin mark 62, the characters in the middle will be filled and the cursor K will move. Indent mark 61 position.

The control unit 2 reads the contents of the position of the cursor K in the text memory, and determines whether or not the right end of the block has been reached, in other words, the mark (indent mark, margin mark and vertical mark) that defines the block end at the cursor K position. Ruled line-This is, for example, 01010000 which is equivalent to a vertical ruled line-)
Check whether is written. Character writing and cursor stepping are repeated until the right end is reached, but when the right end is reached, the control unit 2 next checks whether that position is the right end of the last line of the block. This is the case where the contents of the next line portion just below the cursor position is read from the text memory and the read code is a block edge defining mark (indent mark) as shown by the chain double-dashed line in FIG. 9 (a). Moves the cursor K to the left end in the same block on the next line, assuming that it is not the right end of the last line of the block. On the other hand, if there is no block edge defining mark, the block edge defining mark in the line of the current cursor K is copied and written in the corresponding position of the next line (in terms of processing, the original cursor line, that is, the current line and the next line). The line in which the mark is copied is inserted between and (Fig. 9 (b)).

When the block edge defining mark is an indent mark, the block edit area is expanded one after another by repeating such processing. This expansion can be stopped by deleting the newly copied indentation mark by operating the cursor movement key 15 and the "blank" key 16.

Also, if you perform an operation such as a line feed before reaching the right end of the block, the enlargement will be automatically stopped.

After copying the indentation mark as shown in Fig. 8,
The presence or absence of a table in this copy line or inserted line, in other words, the presence or absence of a ruled line code, is checked, and then it is checked whether or not it is the end of the table [the end of the table is shown in FIG.
The code is as shown in (g)]. If it is not the end of the table, even if there is a ruled line code, it will be in the state of waiting for key input as in the case of the indent mark.

Therefore, as shown in FIG. 5, in the case of the table with the lower end opened, the indent mark is extended by the vertical ruled line in a mode of copying.

Such a downward extension process of the table is similarly performed when characters are input inside the table whose lower end is closed in advance (horizontal line of lower end is drawn beforehand) as shown in FIG. Explaining this with reference to FIG. 10 (a), the bottom line in the table (a horizontal line occupies one line by itself, so no characters are written in the horizontal line. Therefore, the bottom line in the table is the line of the horizontal line. When the cursor K reaches the position of the vertical ruled line, the control unit recognizes that the cursor K has reached the right end of the block, and recognizes that it has reached the right end of the block. The code (indicated by a chain double-dashed line) is read from the text memory. Then, it becomes 01000100, and it is judged that the current cursor position is at the right end of the last line of the block, and as shown in FIG. 10 (b), a block end defining code, here a line having vertical ruled line 01010000 at two places. Insert.

This operation is defined as a table frame extension process.

In other words, in this table frame extension processing, when the cursor position that indicates the input position of the character / symbol string moves to the ruled line that divides the table frame, the code at that position in the next line is the bottom right corner of the table frame. When it is determined that the ruled line code indicating
Insert space lines with the same ruled lines as the table frame at both left and right ends to extend the table frame downward.

After this table frame extension process, the presence or absence of a table is checked for the inserted row. However, since there is no code indicating the end of the table in that row, for example, the code in FIGS. 7 (f) and 7 (g), the cursor is inserted. Moves to the next line and waits for key input on the next line.
The block edit area is also expanded downward during writing in the closed table.

On the other hand, in the case of FIG. 6, unnecessary extension of the table is not performed. When the cursor K is positioned on the left vertical ruled line 65 of the table in the line immediately above the bottom horizontal ruled line as shown in FIG. 11 (a), the control unit 2 causes the code of the display unit below the cursor position to be displayed. From FIG. 7 (f), it is determined that the current cursor position is not at the right end of the last line of the block, and the cursor K is advanced to the left end of the next line [FIG. 11 (b)].

When the cursor K reaches the display section at the lower left corner of the table [Fig. 11 (c)], the character is judged to be the right end of the last line of the block this time, and the block end regulation mark of that line is displayed. Insert the copied line between itself and the next line [Fig. 11 (d)].

However, this insertion line contains the code of the table, and since it indicates the end of the table, next replace the code of 01000001 in the lower left of the table and the code of 01000100 in the lower right of the table with the code of indent mark 61, and move the cursor. It moves to the left end of this replaced line and waits for key input.

Thereafter, as shown in FIG. 6, the block edit area is enlarged by the indent mark 61. Figure 11 (d)
The state of is not actually visible.

The reason why such processing is performed is that a space is provided immediately below the table, and the title of the table, a comment, etc. can be easily entered for this space. Therefore, for the vertical ruled line inside the table as shown by the two-dot chain line in FIG. 6, the block edit area is not enlarged by adding the indent mark.

(G) Effect of the Invention According to the present invention, since the table frame extension processing is performed when the code immediately below the cursor position is the ruled line code indicating the lower right corner of the table frame, the table frame extension is performed. Judgment for extension processing can be easily performed.
