Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Usage The present invention relates to a document processing device suitable for use in word processors and the like.

(b) Prior Art Currently, word processors that input and edit documents while looking at a CR7 screen and then print them out on a printer are becoming widespread.

Such a word processor has a document input function, an editing function such as a function to delete or add an input document, and also a function to arbitrarily specify the input document and the size of symbols.

For example, in the device disclosed in the 'Bunsaku π Operation Manual' published on July 1, 1985, half-width,
It has a cursor whose size can be arbitrarily selected from full-width and double-width, and the display size of input characters, etc. is determined according to the size of the cursor.

(c) Problems to be solved by the invention When trying to change the obstacles such as characters and symbols that have already been inputted, such devices first change the size of the characters or symbols whose size they are trying to change. After moving the cursor to the position of the symbol, etc., and changing the cursor to a desired size, the user must input the characters, symbols, etc. again, making the operation complicated.

(d) Means for Solving the Problems The present invention has been made in view of the above points, and is intended to provide a document processing device that can easily change the size of input characters, symbols, etc. , its structural feature is that it is a device that can arbitrarily change the size of the cursor that indicates the processing position on the CRT screen, and is equipped with a cursor change key, a cursor change means, a font size change key, and a font size change means. That's true.

(f) In an apparatus having such a configuration, when a cursor change instruction signal is input from the cursor change key, the cursor change means changes the size of the cursor on the CRT screen, and also changes the size of the cursor from the character size change key. By inputting the character size change instruction signal, the character size change means can change the pattern of characters, symbols, etc. located at the position indicated by the cursor to the size of the cursor.

(v) Embodiment Figure 1 shows an embodiment of the present invention, (1) is a keyboard as an input means, and the i-keyboard is a character key for inputting characters, symbols, etc. as shown in the second prisoner. Group (2),
A group of function keys (
3), cursor movement key (4), cursor change key (5)
), and a character size change key (6). (7) is a key determination section, which determines the type of key pressed on the keyboard (1) and outputs a corresponding hood.

(8) is a document storage device, and the document storage device is a CRT.
Codes corresponding to the characters/symbols, etc. to be displayed on the screen (9) and display size indicating whether the above characters/symbols, etc. are to be displayed in half-width, full-width, double-width, etc. on the CRT screen (9) Information is stored in pairs according to display order and display position. (10) is a font ROM, which is a full-width dot pattern (for example, 24
24 dot patterns), and when the above code is input, a dot pattern corresponding to the code r is output. (11) is a character size changing means, which converts the dot pattern output from the font ROM (1G) into a display size stored in the document storage device in pairs with a hood corresponding to the dot pattern. The dot pattern is enlarged or reduced to double-width, half-width, etc. based on the information. (12) is a VRAM in which dot patterns to be displayed on the CRT screen (9) are stored in one-to-one correspondence with display positions on the CRT screen (9). (13) is a cursor changing means, which comprises a cursor position storage section (14) in which the cursor and crane display positions on the CRT screen (9) are fully memorized;
9) Based on the contents of the cursor size storage unit (15) that stores the display size of the cursor on the
2) Write a cursor pattern inside the cursor pattern. In this embodiment, the cursor patterns shown in Fig.
As shown in the figure, there are five types: half-width, full-width, double-height, double-width, and quadruple-width. Note that the character “A” in the figure is full-width size.

Further, the cursor change means (13) rewrites the contents of the cursor position storage section (14) every time the cursor movement key (4) is pressed, and the cursor change key (
Every time 5) is pressed, the contents of the cursor size storage section (15) are rewritten. The contents of the cursor size storage section (15) are cyclically rewritten each time the cursor change key (5) is pressed. That is, as shown in FIG. 4, if information indicating "full-width" is currently stored in the cursor size memory section (15), the above information is stored each time the cursor change key (5) is pressed. The information is changed as follows: "height x 1 x width x 1" = 4 x 4 x x 4 ->"half-width" x x "full-width"-> .

(16) is a main control unit that controls each of the above-mentioned parts and means, and the main control unit is composed of, for example, a microcomputer, and performs control based on a built-in control program.
The operation of the apparatus of this embodiment will be explained below based on such a control program.

First, in step S1, it is determined whether or not the character/symbol key (2) is input from the keyboard (1). Such a determination is inputted from the keyboard (1) and sent to the key determination section (7).
), and if it is determined that the code corresponds to a character/symbol, the process proceeds to step S2; otherwise, the process proceeds to step S3.
Proceed to step.

In step S2, the hood outputted from the key determination section (7) is written into an area in the document storage device (8) corresponding to the cursor display position information stored in the cursor position storage section (14). When the step is completed, the process is 513
Proceed to step.

Further, in step S3, it is determined whether or not the cursor movement key (4) has been input from the keyboard (1).

Such a judgment is inputted from the keyboard (1) and sent to the key judgment section (
Based on the food output from step 7), if the code corresponds to cursor movement, the process advances to step S4.

In step S4, the cursor is moved in any one of the up, down, left, and right directions indicated by the input of the cursor movement key (4) by the amount of the displayed size. Such movement can be performed by changing the cursor display position information in the cursor position storage section (14) based on the movement instruction direction and the cursor size information in the cursor size storage section (15).

Upon completion of step S4, the process proceeds to step S13.

Returning again to step S3, if it is determined in this step that the cursor movement key (4) has not been input, the process proceeds to step S5.

In step S5, it is determined whether or not the cursor change key (5) has been input based on the output from the key determination section (7). If it is determined that the cursor change key (5) has been input in the refusal determination, the process proceeds to step S6; otherwise, the process proceeds to step S7.

S 6 Z f y 2 T +t calf tL, ?
4□□(15) The cursor size information of "P'l" is changed. This change is caused by inputting the cursor change key (5) from the main control unit (16) to the cursor change means (13). For example, if the cursor size storage section (15) stores information representing "full-width size," inputting the cursor change key (5) changes the stored information to "double height size." When step S6 is completed, the process advances to step S13.

Further, in step S7, it is determined whether or not the character size change key (6) has been input based on the output from the key determination section (7). In such a judgment, if it is determined that the font size change key (6>) has not been input completely, the process proceeds to S shown in Fig. 6.
Proceed to step 8.

In step S8, the cursor size information stored in the cursor size storage section (15) is read, and in step S9, the cursor size information and the document storage device (14) corresponding to the cursor display position in the cursor position storage section (14) are read. 8) Compare the width of the current cursor with the character width at the cursor position based on the display size information stored in the area within (character width)
If it is determined that (cursor width), the process proceeds to the SIO step, and if it is determined that (character width) < (cursor width), the process proceeds to step 511, and then (character width) - (
If it is determined that the width of the cursor is the width of the cursor, the process proceeds to step 512.

In step S10, (character width) - (cursor width)
), specifically, the document storage device (8
), the arrangement position is changed so that the information existing after the area corresponding to the cursor display position information in the cursor position storage unit (14) is compressed by the above-mentioned difference.
If we assume that the character width is full-width and the cursor width is half-width, the above padding width will be only half-width.

Also, the 311 step is symmetrical to the 510 step (
Inserts an area corresponding to the cursor display position in the cursor position storage unit (14) in the document storage device (8). Shift the information backward by the above difference,
Change the placement position so that information on large characters/symbols corresponding to the width of the cursor can be entered in the area corresponding to the cursor display position.0 For example, if the current character width is full-width size and the cursor width is double If it is the size, the width to be shifted backward is the total amount.

When steps 510 and S11 are completed, the process proceeds to step S12.

In step 512, the display size information stored in pair with the hood stored in the area in the document storage device (8) corresponding to the cursor position is converted to the cursor size information stored in the cursor size storage unit (15). Rewrite it as . When the step of refusing is completed, the process proceeds to step 313.

In step S13, the contents of VRAM<12) are rewritten. This reads the code and display size information from the document storage device (8) into its storage, and also reads the font ROM (1G) and character size changing means (1G) based on the image information.
1) forms a font pattern with a desired sharpness, writes it to the corresponding position on the VRAM (12), and then writes it to the cursor position storage section (14) and cursor size storage section (14).
Based on the information in 5), the cursor □ changing means (13) is set to V.
This is done by writing the cursor pattern into RAM<12). When step S13 ends, the process returns to step S1.

In order to make the above operation easier to understand, a specific example will be shown and explained.

First, as shown in FIG. 7(a), a full-width "A" and a half-width "B" are displayed on the one-line CR1 screen (9).

“C”, full-width D” gg” 11F”, half-width “
"G" and "H' are displayed sequentially from the left end, and the full-width "
Assume that a full-width cursor (20) is displayed at position A''.

When the cursor change key (5) is input in such a state, steps Sl, S3, S5, and S6 are processed in sequence, and the cursor (20) is changed to double height as shown in FIG. Ru.

Next, when the font size change key (6> has been inputted, press SL,
Chips S3, S5, S7, S8, and S9.312.813 are processed in sequence, and the character "A" at the cursor position is changed to double height as shown in FIG. 7(c).

In addition, when the cursor movement key (4) indicating right movement is input in the state shown in FIG. 7(C), S1, S3, S4
, S13 steps are sequentially processed, and as shown in FIG. 7(d), the cursor (20) displays the character 'B''.

Move to “C” position.

Furthermore, when the cursor change key (5) is inputted, SL, S
3, S5, and S6.513 steps are processed sequentially, and the seventh
As shown in Figure (e), the cursor (20) is changed to double the horizontal size.

After that, when the font size change key (6) is fully input, S
l, S3, S5, S7, S8, S9, Sll, S12,
The S13 steps are processed in sequence, and as shown in Figure 7 (f'), the half-width character "B" is changed to double horizontal size, and the characters 'G' and 'H' disappear from the top of the CR1 screen (9). .

Next, if you press the cursor change key (5) twice in succession and press the cursor movement key (4>, which indicates movement to the right) five times, a loop consisting of steps Sl, S3, S4, S5, S6, and S13 will be executed. After cycling twice, Sl, S3
, S4. A loop consisting of 313 steps is cyclically processed five times, and a half-width cursor (20) is displayed at the left half position of the character 'D' as shown in FIG. 7(g).

If the font size change key (6) is input in this state, S
l, S3, S5, S7, S8, S9, S 10°312
．． 313 steps are sequentially processed, and as shown in FIG. 7(g), the full-width character "D" is changed to half-width size, and the character "F" can be displayed again on the CRT screen (9).

(G) Effects of the Invention As described above, in the apparatus of the present invention, the size of characters, symbols, etc. can be easily changed by simply operating the cursor change key and the character size change key.
