Abstract

PURPOSE:To correct a misinput without moving a cursor corresponding to a character inputted in error by retrieving character sorts successively from a character existing on the nearest position from the cursor by using a character to be corrected and converting the retrieved character sort into other one. CONSTITUTION:A conversion key 11 on a keyboard converts a 'KANA' (Japanese syllabary) into 'KATAKANA' (square form of Japanese syllabary) and a conversion key 12 converts a 'KATAKANA' into a 'KANA'. In case of converting a 'KANA' inputted in error into a 'KATAKANA', a user checks the input of a character string or a cursor position while observing a display part 1 and then decides the character to be converted and depresses the key 11 to start processing. Character string data developed in a RAM of a main memory 5 are retrieved forward from the character most close to the cursor, so that 'KANA' characters are successively converted into 'KATAKANA' characters every depression of the key 11. Since a misinput can be corrected without moving the cursor to the character inputted in error, the operatability can be improved and the operating time can be shortened.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a document processing device.

[Conventional technology]

Conventionally, in this type of device, when an incorrect input occurs, such as inputting hiragana instead of katakana, the cursor is moved to the character to be corrected and the character type is corrected.

[Problem that the invention seeks to solve]

However, when the cursor has to be moved over a long distance or when the characters to be corrected are scattered across multiple positions, the operation associated with cursor movement becomes complicated and takes more time. there were.

Therefore, an object of the present invention is to sequentially search for character types such as sentence 001, which exists closest to the cursor indicating the input position among the characters to be corrected, when there is a character whose character type you want to correct. It is an object of the present invention to provide a document processing device which performs conversion into character types and does not require cursor movement corresponding to the character position in the character type correction.

(Means for Solving the Problem) To this end, the present invention provides a position specifying means for specifying the position of a character to be input, and an instruction for converting a predetermined character type of input characters into another character type. A character type conversion instructing means for performing the above, and a predetermined character type located at a position before the position specified by the position specifying means and closest to the specified position based on the instruction of the character type conversion instructing means. The present invention is characterized by comprising means for converting the characters into other character types.

(Operation) According to the above configuration, when an erroneous input is made, it is possible to correct the erroneous input without requiring a cursor movement corresponding to the erroneously input character.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail and specifically based on the drawings.

FIG. 1 is a block diagram showing the configuration of an apparatus according to an embodiment of the present invention, in which 1 indicates a display unit such as a CRT;
2 is a video RAM (VRAM) that expands and stores pixel information corresponding to the screen of the display unit 1; 3 is a display control unit that expands and stores pixel information in the VRAM 2 and C of the related information;
R7 A microprocessor (MPLI) that sends data to the display unit 1, and 4 controls the entire device of this embodiment.
, 5 is a main memory having a ROM for storing programs for processing described later in FIG. 4, and a RAM used for the above processing. Reference numeral 6 denotes an external magnetic disk device for storing the created document file displayed on the display unit 1, and 7 a pointing device (PD) for specifying an input position using a cursor or the like on the display screen of the display unit 1. Yes, the PD 7 is configured so that input is performed using, for example, a cursor movement key. 8 is a keyboard having conversion keys 11 and 12 according to the embodiment of the present invention as part thereof; 9 is an I1 for connecting each of the above parts and MPLI 4;
0 bus.

FIGS. 2(^) and (B) are schematic diagrams showing details of the conversion keys 11 and 12 on the keyboard 8. The conversion keys 11 and 12 are used in the processing described later, and convert hiragana to katakana, and This is for converting katakana to hiragana.

FIGS. 3 and 4 are a schematic diagram and a flowchart, respectively, of display examples relating to the process of converting erroneously input hiragana into katakana.

Hereinafter, the processing of this embodiment will be explained for each step in FIG. 4 with reference to FIG. 3.

First, in step 541 or 542, the user determines whether a character string has been input or a cursor has been moved. In other words, the user can check the input of a character string as shown in FIG.
Confirm that it has moved to the position indicated by 10 in the figure. If an affirmative determination is made in any of the above steps, the process proceeds to step 543, where the user determines whether or not there is a character to be converted in the input character string. That is, after inputting a character string as shown in FIG. 3(A), the user determines that "Amerika" is an incorrect input, first determines "Ka" as the character to be converted, and proceeds to step 544. , the user determines that the character to be converted is hiragana, presses the conversion key 11, and proceeds to step S45.

The following steps 545 and 546 are not performed by the user as described above, but step 544
This is a process that is started by pressing the conversion key in , and is performed by the device of this example. That is, in step 545, the character type to be converted is recognized as hiragana by inputting the conversion key 11 in step S44, and the character string data developed in the RAM in the main memory 5 is converted using the corresponding character type code. Search forward starting with the character closest to the cursor. As a result, the hiragana "ka" is identified as the corresponding character,
In step S46, the katakana character is converted into ``Chiki'', that is, the corresponding data in the RAM is changed and displayed as shown in FIG. 3(B).

After completing the process in step 54B, the process returns to step 543.

Here, if there are still characters to be converted as shown in FIG. 3(B), the third
As shown in Figures (C) to (E), the conversion key 1 is
Conversion is performed by manipulating 1.

In the above example, we have explained the case of converting hiragana to katakana, but it goes without saying that if you press the conversion key 12 instead of the conversion key 11, katakana can be converted to hiragana through the same process. .

In addition, if you want to change ``Ameri'' to katakana while leaving ``KA'' as is in the display example in Figure 3 (^), move the cursor to the ``KA'' position and repeat the process described above.
It is clear that "Ameri" is converted to "Ameri".

Furthermore, in the process at step 544 shown in FIG.
If you press a simple conversion key instead of pressing the character type conversion key 11 or 12, and then search and identify the character type using multiple predetermined character type codes on the device side, key operations can be It becomes easier.

Additionally, the character type that can be converted is not limited to one as in the above example, but may be configured to be convertible into a plurality of character types. Moreover, although the conversion between hiragana and katakana has been described, it goes without saying that the present invention can be applied to conversion of fonts such as Gothic and Mincho fonts.

(Effects of the Invention) As is clear from the above explanation, it is possible to correct the incorrect input without having to move the cursor corresponding to the incorrectly input character.This improves the operability of the device. This has the effect of shortening the operation time involved in correcting erroneous input.
