Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a word processor, and more specifically, it is an object of the present invention to provide a word processor with improved block editing functions.

Hereinafter, the present invention will be explained in detail based on drawings showing embodiments thereof.

FIG. 1 is a block diagram showing the general structure of a Japanese word processor according to the present invention, and FIG. 2 is a diagram showing the layout of a pen-touch type keyboard with all character layouts.
In FIG. 1, 1 is a keyboard, 2 is a control unit including a CPU, 3 is various memories for storing control programs, input text storage, dictionary units, etc., 4 is a CRT,
5 is a printer. Sentences input from the keyboard 1 are stored in the text memory that constitutes the memory 3 by the action of the control unit 2, and along with this,
It will be displayed on CRT4. This text is printed by the printer 5 by giving a print command, and is also stored in a floppy disk provided as an external memory in the memory 3, so that it can be used for subsequent printing.

This word processor has the following block editing functions. To explain this function, first, as shown in Figure 3, if you want to secure a space for pasting a photo on the right side, write a diamond-shaped indent mark 61 on the left side of that space in advance by touching the indent key 11. By doing this, the area narrowed by this indent mark 61 and the left margin mark 62 is edited as one block (when inputting, when the cursor comes to the indent mark, a line break is made. When deleting or adding, it is done within this block, etc.) ). Note that the indent mark is not involved in printing. Also, in order to avoid the awkwardness of writing a large number of indent marks 61, indent marks 6 are placed in the upper line.
By writing 1 in advance, an indent mark is automatically written one after another at the position directly below each line break.

In addition, the product of the present invention has a tabulation function, and as shown in FIG.
Block editing is possible in the area narrowed by 2 and the ruled lines. As shown in Fig. 5, when the table is in an unfinished state, that is, when the horizontal line at the bottom of the table has not been drawn, the text input is performed at the right end of the row corresponding to the bottom end of the vertical line 64 of the table. When it reaches , the vertical line is automatically extended downward and the block editing area of this table is enlarged. And this enlargement function has margin mark 62 and vertical line 6
The same applies to the area narrowed by 4. Such an enlargement function is exactly the same as the enlargement function of a block editing area by automatically writing an indent mark to the next line.

Therefore, the expansion of the block editing area in a table as described above is possible even when a horizontal line is drawn at the bottom of the table and the table is closed in advance as shown in Figure 4, when entering text in this table, the bottom horizontal line is is executed in such a manner that the lines are moved down one line at a time.

On the other hand, when the bottom end of the table is closed with a horizontal line as shown in FIG. As it is being entered,
When the characters are filled to the right end of the area in the last row of the table (along with the horizontal line), the indent mark 61 is displayed at the extended position instead of the vertical ruled line without extending the table, so that text can be input afterward. If the editing is continued, the block editing area is enlarged by adding an indent mark in the same way as described above.

In order to execute the block editing area enlarging function of the product of the present invention as described above, it is necessary to specify the position in the table from the ruled line pattern. First, the tabulation function of the product of the present invention will be briefly explained.

The operation procedure for drawing ruled lines is as follows. That is, the user moves the cursor to the position on the CRT 4 screen where the starting end of the ruled line should be, and then touches the ruled line key 12. In response to this, the control unit 2 executes a predetermined program and displays a pattern to guide the selection of the type of ruled line (thin line, thick line, double line, or broken line). By operating the numeric keypad corresponding to the desired type of ruled line, a cross pattern of the corresponding line type is displayed at the cursor position, and by touching the cursor repeat key 13 in the direction in which you want the ruled line to be drawn, the ruled line is drawn in that direction. To go.

The code for displaying or printing such ruled lines is a 16-bit code, and a ruled line display pattern or a ruled line printing font is assigned to each code. The upper 8 bits of the 16-bit data indicate a ruled line code, and the lower 8 bits specify the font pattern. In this example, the print font is composed of a 32 x 32 dot matrix, and the CRT screen display font is composed of a 24 x 24 dot matrix, but in the case of ruled line fonts, these matrices are extremely limited. portion is used. That is, as shown schematically 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 region 73 extending rightward. This is the area 74 indicating the ruled line part, and the ruled line information (none, thin line, double line, thick line) of each area is assigned to 2 bits each from the upper side of the lower 8 bits of the 16-bit code. be. This is represented by no ruled line: 00, thin line: 01, double line: 10, and thick line: 11, so if the lower 8 bits are 00000000, there is no ruled line in that part, and 00000101 is the font as shown in Figure 7 B. A thin horizontal line that extends across the entire width of the left and right sides of
00000001 is a thin horizontal line that appears only in the right half of the font (a broken line is drawn as a continuation of this) as shown in Figure 7 C, 11111111 is the cross section of the thick line as shown in Figure 7 D, and 10100000 is the 7th line. As shown in Figure E, this becomes a double line extending in the entire vertical direction of the font. Therefore, from the code written in the text memory, it is possible to identify that the display content corresponding to the code is a ruled line (based on the upper 8 bits) and the type of ruled line (based on the lower 8 bits).
In other words, the lower 8 bits of the written data in the text memory, which can be checked in relation to the cursor position, are
If it is 01000001, it has an L-shaped pattern as shown in Figure 7, and this pattern display part is judged to correspond to the lower left end of the table, and if the lower 8 bits are 01000100, it has an L-shaped pattern as shown in Figure 7. It has an inverted L-shaped pattern as shown in FIG.

Now, the process of the control section 2 for enlarging the block edit as described above will be explained based on the flowchart of FIG.

By touching the character key 14, characters are written to the text memory, which causes the CRT to
4, and the cursor is moved each time a character is input. As shown in FIG. 9A, as characters are entered between the margin mark 62 on the left and the indent mark 61 located to the right, the characters between them will eventually become full and the cursor K will move to the indent mark. It will be at the 61st position.
The control unit 2 reads the contents of the cursor K position in the text memory, and checks whether the right end of the block has been reached or not. For example, this is equivalent to a vertical ruled line.
01010000 -) is written or not. Character writing and cursor advancement are repeated until the right end is reached, and when the right end is reached, the control section 2 next checks whether that position is at the right end of the last line of the block. This reads the contents of the next line immediately below the cursor position from the text memory, and if the read code is a block end specification mark (indent mark) as shown by the two-dot chain line in Figure 9A, the block is read out. The cursor K is moved to the left end of the same block in the next line, assuming that it is not the right end of the last line. On the other hand, if there is no block end regulation mark, the block end regulation mark in the current cursor K line is copied and written to the corresponding position in the next line (processing is done between the original cursor line and the next line). (Insert the line where the mark is copied) [Figure 9 B]. If the block end defining mark is an indent mark, the block editing area is expanded one after another by repeating this process. This enlargement can be stopped by deleting the newly copied indent mark by operating the cursor movement key 15 and blank key 16. Furthermore, if an operation such as a line break is performed before reaching the right end of the block, expansion will be automatically stopped.

After copying the indent mark as shown in Figure 8, the presence or absence of a table in this copied or inserted line is checked, in other words, the presence or absence of a ruled line code, and then it is checked whether it is the end of the table. [The table ends with the code shown in Figure 7.] If it is not the end of the table, even if there is a ruled line code, it will be in a state where key input is required as in the case of an indent mark.

Therefore, in the case of a table with an open bottom end as shown in FIG. 5, the vertical ruled lines are extended in the manner of copying the indent mark.

This process of extending the table downward is performed in the same way when characters are input into a table whose lower end is closed (a horizontal line at the lower end is drawn in advance) as shown in FIG. To explain this based on FIG. 10A, the bottom row of the table (the horizontal line occupies one line by itself, so no characters are written in the horizontal line area.
Therefore, when characters are input to the right end of the table (the bottom line in the table is one line above the horizontal line) and the cursor K reaches the position of the vertical ruled line, the control unit indicates that the right end of the block has been reached. The code in the display area under the cursor position (indicated by the chain double-dashed line) is read from the text memory. Then, it is 01000100, and it is determined that the current cursor position is the right end of the last line of the block, and the block end specification code, in this case 01010000 of the vertical ruled line, is set to 2.
Insert the line you have at the location. The inserted line is checked to see if there is a table, but since there is no code indicating the end of the table, for example, the code in Figure 7, the cursor is moved to the inserted line and waits for a key input on the next line. become a state. In this way, even when writing into a closed table, the block editing area is expanded downward.

On the other hand, in the case shown in FIG. 6, the table is not extended unnecessarily. As shown in Figure 11A, the left side ruled line 65
When the cursor K is located at the block, the control unit 2 determines that the current cursor position is not at the right end of the last line of the block based on the code on the display below the cursor position (see Figure 7), and moves on to the next block. Move cursor K to the left end of the line (Figure 11B). Then, when the character input continues and the cursor K reaches the display area in the lower left corner of the table [Figure 11C], this time it is judged to be the right end of the last row of the block, and the block end specification mark of that row is copied. Insert the line between the next line [Figure 11 D]. However, this inserted line contains the table code, which indicates the end of the table, so next, replace the codes 01000001 at the bottom left of the table and 01000100 at the bottom right of the table with the code at indent mark 61, and move the cursor to this code. Move the key to the left end of the replaced line and wait for input. Thereafter, as shown in FIG. 6, the block editing area is expanded using the indent mark 61. Note that the state shown in FIG. 11D is not actually visually recognized.

Note that this process is performed by creating a margin directly below the table, and adding the title of the table to this margin,
This is to facilitate the entry of annotations, etc. Therefore, the block editing area is not enlarged by adding an indent mark to the vertical ruled lines inside the table as shown by the two-dot chain line in FIG.

As described above, the word processor according to the present invention is a word processor equipped with a block editing function, and the block definition information that defines the block is
It includes at least an indent mark as block regulation information that is not printed but displayed on the screen, and a ruled line as block regulation information that is printed and displayed on the screen, and in the block inside the table constituted by the ruled lines, the corresponding When character information is input to the right end of the last line of a block, the block is extended by one line, and one end of the last line of the side block is defined in the side block outside the table made up of the ruled lines. If the ruled line indicates the end of the table, when character information is input to the right end of the last line of the block, an indent mark is added at the same position below the ruled line that defines one end of the last line. If the ruled line that defines one end of the last row of the block is extended by one line and there is no ruled line that indicates the end of the table, when character information is input to the right end of the last line of the block, the last line Since the block is configured to extend by one line by attaching the same ruled line at the same position below the ruled line that defines one end of the line, it is not necessary to specify the lower limit of the block editing area in advance. You can enjoy the convenience of automatically extending the table without any special operations, and if you have set the table size in advance,
Even when there is insufficient space for writing characters in a table due to an error in character count calculation, etc., the table is automatically enlarged downward, providing convenience. Furthermore, when entering characters in the block editing area on the side of the table, the unnecessary downward expansion of the table as described above is not performed, and the lower part of the table is automatically blanked out and used as a separate block editing area. As a result, a word processor with extremely useful block editing functions can be realized.

Note that the present invention is equally applicable to a Japanese word processor of the kana-kanji conversion type and a Roman word processor.
