Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention [Field of Industrial Application] The present invention relates to a document editing device, and more particularly to a document editing device having a character modification function.

[Prior Art] Conventionally, as this type of document editing device, underline (Δ), bold printing (B), super script (32
), subscript (H2'0) ci, or strikeout (e 100 sho), specify the character modification range by moving the cursor, etc., and set/cancel the character 1fff for this range. It is known that there is a separate designation of i. It has also been proposed that keys are provided for individual character modification functions, and when the keys are pressed, the cursor moves while modifying the characters.

[Problems to be Solved by the Invention] However, these document editing devices have the following problems, and improvement of the demand has been desired.

(1) If the range of character modification and the content of the character segment are specified separately, there is a problem in that the number of manual keystrokes increases accordingly, making the operation complicated.

Particularly for users who are not familiar with the operation of the Sentence N editing device, specifying a range and modifying characters is not intuitive, making it difficult to understand and hindering the user's skill.

(2) If a key is provided specifically for character modification, and pressing the key modifies the character and moves the cursor,
Since the direction in which the cursor moves is limited, if you want to cancel the last character decoration, you must move the cursor to the beginning of the range you want to cancel each time, specify that you want to cancel the character decoration, and then use the special There was a problem in that a complicated operation of pressing a key was required.

The present invention aims to solve these problems and provides a document editing device with easy-to-use character modification functions.

Structure of the Invention [Means for Solving the Problems] In order to achieve the above object, the present invention has the following structure as a means for solving the problems. That is, in a document editing device having a function of displaying at least a part of a document being edited on a display and modifying characters constituting the document, a modification content specifying means for designating the content of character modification; A character modification that moves the position of a cursor in a displayed document in a predetermined direction, and sets or cancels a character gardener specified by the modification content designation means for the characters of the document that move within the movement range of the cursor. This is the structure of a document editing device characterized by comprising an execution means. Here, the character modification execution means moves the position of the cursor in the displayed document in a predetermined direction, and specifies characters of the document over the moving range of the cursor using the modification content designation means. a character decoration setting means for setting character decorations; and a character decoration setting means for setting character decorations; It is also preferable to include a character modification canceling means for canceling the character decoration specified by the means.

[Operation] The document editing device of the present invention having the above configuration uses the character modification execution means to
The character decoration specified by the decoration content specifying means is set or canceled to decorate the characters constituting the document being edited.

[Embodiment] In order to clarify the configuration of the present invention described above, a document editing device as a preferred embodiment of the present invention will be described next. FIG. 1 is a block diagram showing a schematic configuration of this document editing device.

As shown in the figure, the document editing device of the embodiment includes a keyboard 1 for inputting characters and editing instructions, a display device (CRT display) 3 for displaying characters and figures, a flexible disk drive 5 as an external storage device, and a keyboard 1 for inputting characters and editing instructions. It is comprised of a printer 7 that prints graphics, an electronic control device 10 that is connected to these devices, and controls document input, editing, and printing. The electronic control device 10 includes a well-known CPU 11
゜ROM12. A video RAM 15, which is configured as an arithmetic and logic operation circuit mainly including a RAM 14, stores image data such as characters and figures to be displayed on the CRT display 3, a keyboard input port 16, which inputs key data from the keyboard 1, and a flexible disk drive. The flexible disk drive controller 18 controls the printer 5 to read and write data, and the printer output port 20 outputs print data to the printer 7. Further, the video RAM 15 has a so-called dual port RAM configuration, and is configured to be accessible also by a CRT controller 22 provided independently of the CPU 11. The CRT controller 22
The content of the video RAM 15 is repeatedly read out on the display at a period determined by the scanning frequency of 3, and this is CR
Display on T display 3. Therefore, data written into a predetermined area of the video RAM 15 by the CPU 11 is immediately displayed on the CRT display 3.

The keyboard 1 includes a character key 31 for inputting characters, a character modification key 33 for specifying each character modification, and a cursor to the right (→).

Cursors 35R, 35L, 35U, and 35D are provided for moving left (←), up (↑), and down (↓).

The user inputs a document by pressing the character key 31, and selects various functions such as underline and superscript as necessary to set or cancel character decorations corresponding to the input document. be able to. Also,
The created document can be written to a flexible disk set in the flexible disk drive 5 via the flexible disk drive controller 18, or can be output to the printer 7.

Next, how to set and cancel the character ρ decoration will be explained with reference to the flowchart shown in FIG. The document collection device of this embodiment inputs and edits English text, and each character constituting the text is represented by 2 bytes (16 bits).

Each of the upper eight bits is used as a flag indicating the content of the character modification. Also, right cursor key 35R2
The down cursor key 35D is used as a setting key for the specified character modification, while the left cursor key 351. Each of the upper cursor keys 35U functions as a key for canceling specified character decoration.

When the document editing device presses any key on the keyboard 1, it starts the character modification mode input editing control routine shown in FIG. 2, and first determines whether or not the current input mode is in the character modification state. (Step 100). That is, if even one character modification key 33 on the keyboard 1 is pressed, it is determined that the character modification state is in progress, and the processing from step 110 onward is executed; if none of the character modification keys 33 is pressed, , it can be handled as is in rNEXTJ, and key input is performed using a normal input processing routine (not shown).

In the case of the character modification state, it is determined whether the input from the keyboard 1 is a character key input manually (step 110), and if the character key is input manually, the code of the input character is stored in the text area of the RAM 14. is set at a predetermined position, and a character modification flag is attached to the character (step 120). A character consists of 2 bytes, and each of the upper 8 bits is used as a flag indicating the character modification state, so the bit corresponding to the character modification is set to '1'. The correspondence between each bit and character modification is as follows. Therefore, if Angline is specified, the 2° bit of the upper byte of the character code is set to 1 in step 120.

Next, the content of the video RAM 2S is rewritten according to the text content (step 130). That is, since the display on the CRT display 3 uses a so-called bit map display method, it should be displayed in a form with character modifications such as underlining, depending on the character code stored in the text +-. The character string is expanded to video RA1'''V115. As a result,
On the display 3, the text is displayed with the specified character modification as it is. After the above processing, rNEXTJ can be handled and this control routine is temporarily ended.

On the other hand, if the key input from the keyboard 1 is a key other than a character key, the determination at step 110 described above is rNOJ, and a determination is made as to whether the key input was cursor key input (step 140). If it is not a cursor key, it is assumed that it is not a character key or a cursor key (for example, in the case of a carriage return key or a tab key), then the command ``Proceeds to NEXTj'' and ends this routine.

Among the cursor keys, especially the right cursor key (r-J)
35R, down cursor key (“↓”) 35D, a character modification flag is attached to each character of the text within the range where the cursor has moved (step 150);
Further, the process proceeds to step 130 described above, and a display with character decoration is performed. As a result, Figure 3 (A), (B
), as shown in (C), character decoration (underline in this case) is applied over the range in which the cursor (shaded area) is moved by one force. Note that since the character decoration flag that has already been set is not changed, character decoration will be applied to all characters within the movement range of the cursor.

On the other hand, the key power is left cursor key (“←”) 35L,
If the upper cursor key ([↑J) is 35U,
As a result, the character modification flag of each character in the text within the range to which the cursor has moved is cleared (step 160) and displayed (step 130). As a result, Figure 4 (A
) and (B), character decoration (here, subscript) is canceled over the range to which the cursor (shaded area) has moved. Note that since the character decoration flag that has already been cleared is left as is, all characters within the movement range of the cursor are displayed without any character decoration.

According to the document editing device of the embodiment configured as described above, it is possible to easily set/cancel the character modification specified by the character modification key according to the movement of the cursor keys 35R, U, L, and D. Character modifications can be manipulated with fewer keystrokes.

In particular, character modification can be set using the "→" and "↓" cursor keys 35R and 35D, and can be canceled using the "←" and "↑" cursor keys 351.35U. When making decorations, for example, if you have added too many character decorations, you can cancel them very easily. Therefore, good usability is achieved when handling character decorations. Fifth
Figures (A), (B), (C), and (D) show examples of operating the cursor keys 35D and 35L when underlining text from the 10th character on the second line to the 6th character on the fourth line. However, it is easy to see how the operation is simplified and consistent with intuitive operation.

Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment in any way. It goes without saying that the present invention can be implemented in various ways without departing from the spirit of the present invention, such as a configuration in which a control code surrounds the range of character modification.

As described in detail about the invention, the document editing device of the present invention has an excellent advantage of being able to extremely easily handle character modification and greatly improving the usability of the character modification function. be effective. Therefore, it is possible to reduce the time required to edit a document including character decorations, and to improve the work efficiency.
