(B) Conventional technology Conventionally, underlining,
There has been a document preparation device (word processor SWP-7700 manufactured by Sanyo Electric Co., Ltd.) having a function of repeatedly inputting modified characters such as hatches (hereinafter referred to as repeat). In such a conventional document creating apparatus, in order to repeat input a modifier character, a character modifier is instructed from a keyboard, a desired modifier character is selected from several types of modifier characters displayed, and then a repeat direction is designated. By doing so, the selected modifier character can be continuously input. However, when the modifier character is input again, the modifier character to be input must be selected even if the modifier character is input again. There is a drawback that the operation is troublesome when extending the time.

In addition, to delete a modifier character that has already been input, the character modification is instructed, and then deletion is selected by selecting undo and instructing the repeat direction. However, as with the modification character input, the operation is cumbersome. there were.

(C) Problems to be Solved by the Invention The present invention has been made in view of such circumstances, and when there is a modifier character that has already been input, when extending the modifier character, or when modifying the modifier character, When deleting,
It is an object of the present invention to provide a document creation device capable of easily performing the operation.

(D) Means for Solving the Problems A document creation device according to the present invention comprises: a storage unit for storing character data including at least code data and an attribute indicating whether or not a modifier character is added or a type of the modifier character added; Display means for displaying the character data stored in the storage means; cursor means for moving on the display screen of the display means to specify a position on the display screen with a cursor; Instruction means for designating that only the attribute of the character data corresponding to the specified position is repeatedly input, and storing the attribute of the character data corresponding to the position specified by the cursor means when the repetitive input is instructed by the instruction means. When the cursor is moved after the repetitive input is instructed by the instructing means, the attribute storage means is moved to a position designated by the cursor. The attributes of the character data to be made more and converting means for converting the attribute stored in the attribute storage means.

(E) Operation As described above, the means for storing the attribute of the character data for which repetitive input has been instructed, and converting the attribute of the character data corresponding to the position of the cursor to the stored attribute when the cursor is moved. With this arrangement, it is possible to repeatedly input a modifier character such as a hatch or an underline, and delete a modifier character that has already been input.

(F) Embodiment FIG. 1 is a block diagram showing the configuration of an embodiment of the document creation apparatus of the present invention.

In the figure, reference numeral (1) denotes a keyboard, which includes various keys such as a repeat instruction key (instruction means) for instructing a character modification repeat, and a repeat direction instruction key for instructing a character modification repeat direction.

(2) is a cursor counter (cursor means) for moving the cursor in the direction designated by the repeat direction designation key, and has variables (X) and (Y) for storing the current cursor position.

(3) is a text buffer (storage means) for storing character data of the created document, and the character data includes code data, character size data, whether or not modifier characters are added, and what kind of modification. It is composed of data indicating the attribute of the character such as whether the character is added, that is, the attribute.

(4) The character buffer at the cursor position stored in the cursor counter (2) is stored in the text buffer (3).
(5) is a one-character buffer for storing the character data of one character read by the character data reading unit (4), and (6) is a character data storage unit for the character data stored in the one-character buffer. This is a character attribute determination unit that determines the attribute (for example, underline is '100', hatch '20
It is stored in a variable TYPE (attribute storage means) having “0” and “000” for no modifier character.

(7) is a character attribute conversion unit (conversion means) which converts the attribute of the character data stored in the one-character buffer (5) into the attribute indicated by the variable TYPE of the character attribute determination unit (6).

(8) is a character data writing unit for writing the converted character data stored in the one-character buffer at the cursor position in the text buffer (3), and (9) is a display unit (display means) including a CRT, LED, etc. ) And (10) are control sections for controlling the respective sections in response to various inputs from the keyboard (1).

Next, the character modification repeat operation of the document creating apparatus of the present invention having such a configuration will be described with reference to the flowchart shown in FIG. 2 and the character modification repeat operation on the display screens of FIGS. 3A to 3D. Will be explained.

It is assumed that a document as shown in FIG. 3A is currently displayed on the screen of the display unit (9). 'Am' in the document
In addition, a double line underline is added to “twist”, and these document data are stored in the text buffer (3). The cursor (C) is located on the "previous" character in the document, and the cursor position is the cursor counter (2).
(X) and (Y).

First, in step 1, when the control unit (10) detects that the repeat instruction key of the keyboard (1) has been pressed, the process proceeds to step 2, where the character data ('previous') at the current cursor position is stored in the text buffer (3). ) Is read out by the character data reading section (4) and stored in the one-character buffer (5).

Next, in step 3, the attribute of the character data stored in the one-character buffer (5) is determined by the character attribute determining unit (6), and in step 4, the attribute (double line underline '110') is Variable TY of attribute judgment unit (6)
The variable TYPE is transmitted to the character attribute conversion unit (7) in step S5.

The preparation for the character modification repeat is completed by the processing up to this point, and in step 6, the input of the repeat direction instruction key is awaited. Here, if there is no input of the repeat direction instruction key or there is an input of another key, the character modification repeat operation is terminated. However, when the input of the repeat direction instruction key is detected, the process proceeds to step 7 and the cursor counter (2) )
Moves the cursor (C) in the designated direction.

Next, in step 8, the character data reading unit (4) reads the character data at the cursor position and stores the character data in the one character buffer (5). Next, in step 9, the character attribute conversion unit (7) converts the attribute of the character data in the one-character buffer (5) into the variable TYPE (double line underline '11) transmitted in step 5.
0 '). When attribute conversion of character data is completed,
In step 10, the character data is written by the character data writing unit (8) at the cursor position in the text buffer (3), and the process proceeds to the next step 11, where the converted character data is displayed on the display unit (9). You. FIG. 3B shows the operation when the repeat direction is instructed from left to right, and a double-line underline is added to the character "1" by the processing described above. Further, when it is desired to extend the double line underline in the right direction, by instructing the right direction with the repeat direction instruction key, steps 6 to 11 are repeated, and as shown in FIGS. The underline is extended.

In the above description, the case where the modification character such as a hatch or an underline is extended has been described. On the contrary, the modification character which has already been added can be deleted. In other words, when the repeat instruction key is pressed at the cursor position where no modifier character is added and the repeat direction instruction key is operated, the variable TY
In the PE, data '000' representing no modifier character is stored,
The attribute of character data is '000' by the character attribute conversion unit (7)
The modifier character to be converted to is deleted.

(G) Effects of the present invention As is apparent from the above description, according to the present invention, the operation at the time of re-inputting the same modifier character and deleting the modifier character can be simplified, so that the operability can be improved.
