PURPOSE:To facilitate relief at the time of the misoperation of a character kind changeover key by providing a character conversion table which corresponds to plural kinds of characters that input key have respectively. CONSTITUTION:An input device consists of a keyboard 1 on which plural kinds of characters can be inputted with one key by using the input character changeover key in combination, a memory 3 which has the character conversion table corresponding to plural kinds of characters, a display device which displays inputted characters and has a cursor, and a processor 4 which converts the characters. If 'hita' to be inputted in 'HIRAGANA' (cursive form of Japanese syllabary) is inputted in 'ROMAJI' (Roman character) without placing the input mode changeover key in 'ROMAJI' mode by mistake, the display device displays 'kunikachi'. In this case, the range to be corrected is specified with the cursor and the input mode changeover key is pressed, so that 'kunikachi' is converted into 'hita' by the processor 4 according to the conversion table in the memory 4 and displayed correctly on the display device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character input device installed in a word processor or the like, and particularly to a character input device that can easily correct erroneous operation of a switching key.

[Conventional technology]

A character input device installed in a word processor or the like is usually configured so that a plurality of types of characters can be input from a single keyboard surface using switching keys such as input character switching keys. For example, in the character input device of a Japanese word processor, the type of characters to be input in advance, that is, alphanumeric characters.

Select one of hiragana and katakana using the input character switching key. If the input character type is Hiragana or Katakana, the mode is to input the characters as they are read, or
Characters are entered by selecting whether to read the characters in Roman alphabet and enter them using the alphanumeric keys using the input mode switching key. In this case, the switching operation of these switching keys is relatively easy to make an error. For example, when trying to input hiragana in Romaji mode, you may forget to switch using the input mode switching key,
Sometimes I end up typing while in reading input mode. In this case, a completely different character string will be input depending on the key layout defined by JIS. Conventionally, character conversion is one of the remedies for such erroneous operation of a switching key. However, according to this character conversion, you can simply change hiragana to katakana, change full-width characters to half-width characters, or the reverse of each.

It was a simple text replacement.

Therefore, in order to obtain the correct characters after the above-mentioned input error, it was necessary to delete all the incorrectly entered character strings, set the input mode to the correct input mode using the input mode switch key, and re-enter the input again. .

According to such conventional error recovery methods, even though the character string was input incorrectly, the operator must delete the character string that was entered and re-enter the same character string, which is a time-consuming operation. There was a problem with becoming.

[Problem that the invention seeks to solve]

The present invention solves the troublesome remedy that occurs when an operator inputs an incorrect character string by erroneously operating a switching key when inputting characters as described above, and
It is an object of the present invention to provide a character input device that can easily correct erroneous operations with a similar configuration.

[Means for solving problems]

The present invention provides a character input device that inputs characters using input keys while switching the types of characters to be input using a switching key. A character string identified from among the character strings that has already been converted is converted into characters according to the character conversion table, the converted characters are used as internally generated key input, and the converted characters are switched by switching the switching key. This is to make the user re-enter the information.

[Effect]

According to the above configuration, if the operator mistakenly operates the switching key and inputs an invalid character string, the input character string is deleted and there is no need to perform the same key input operation again. Remedies can be easily carried out.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a character input device according to the present invention will be described in detail below with reference to the drawings.

An embodiment of the present invention is shown in FIGS. 1 and 2. FIG.

FIG. 1 is a block diagram showing the configuration of a keyboard-type Japanese word processor to which the present invention is applied.

In the figure, 1 is a keyboard, 2 is a display device, 3 is a memory, and 4 is a processing device. The processing device 4 is provided with a character conversion table, which will be described later, which is a feature of the present invention. Figure 2 shows the key arrangement on the keyboard 1,
This is specified by IS standard C6233. That is, cursor movement key A14. B13. B10. C14, input character switching keys AOI, AO9, C99, input mode switching key A111, character conversion key F14, and each function start/end key (ESC) EOO are added to the character input keys, respectively.

The pestle of this embodiment will be explained below with reference to FIGS. 3 to 10. Figure 3 is hiragana “Hita×Seisaku××”
The character string that would be displayed is the character string that would be displayed if the input mode switch key ALL was not set to Roman alphabet mode and the character string was input using the Roman alphabet reading. If you want to convert this incorrectly input character string into the correct character string [Hita
Enter 4. Next, specify the last position XE and input the character conversion key F14. The specified results are indicated by diagonal lines in FIG. In this case, the X block is Y above the screen display.
In order to distinguish it from the Y block, it is desirable to use an inverted display to make it easier to see. After determining the character conversion target block Set the mode. In this example, the input character switching key is selected with Kana AO9, and the input mode switching key is set to Roman character input mode. Next, by inputting the ESC key EOO, a display in which the X block is converted into a correct character string is obtained as shown in FIG.

In the above operation, the internal processing for converting one character is performed as follows. That is, when inputting one character, alphanumeric characters and katakana characters are sequentially stored in the text buffer memory each time a character is input, and are stored in the order in which the characters are input.

On the other hand, hiragana are stored in the -tan character input buffer memory, and are processed such as kana-kanji conversion before being stored in the text buffer memory. In this embodiment, character strings to be converted are limited to alphanumeric characters, katakana characters, hiragana characters in the text buffer memory, and characters in the character input buffer memory. Next, the above processing will be explained in detail with reference to the flowcharts of FIGS. 6 and 7. Block 1o
In order to obtain the character string to be converted, the cursor display position of the X block shown in FIG. 3 [Xs l XI! Address X5ADR,X[! on the text buffer memory or character input buffer memory corresponding to ADR is stored in the storage register MRI shown in FIG. In block 20, the state of the input character switching key is checked, alphanumeric characters, hiragana characters, and katakana characters are determined, and rOJ and rlJ are respectively selected.
.

Check the switching state 1rfASTATUS of "2" and the input mode switching key, and the input mode M is "0" for normal reading and "1" for romaji reading.
Each OrlR is stored in a storage register MR2 shown in FIG.

In block 30, it is checked whether the characters in the character string to be converted are convertible characters such as alphanumeric characters, hiragana, or katakana.If NG, an error message is displayed in block 4o. If conversion is possible, it is checked in block 50 whether the input mode is Roman characters.

Block 6o stores the character string to be converted and registers MR2
This is a routine that converts each character into a certain character according to the 5TATUS information. For example, if you make a mistake in specifying the input switching key and enter alphanumeric characters in hiragana, the character string ``Kunikachi XXX To Ini Tochinona XXX'' is changed to the correct character string ``hitaxxβe i s a k uxxx J Or convert the character string j yq) < pexh Next, in block 70, it is checked whether or not the conversion has been performed correctly. If the conversion has been performed correctly, the converted character string is displayed on the screen in block 80.

Blocks 90, 100. ．． 120 is 5TATU of MR2
S information is not in romaji, but in hiragana or katakana.
This is the conversion route when OD[E or Romaji. For example, the character string to be converted shown in FIG. 3 is converted as shown in FIG. 5. First, in the character conversion routine of block 60,
The character string to be converted shown in a) is converted into the alphanumeric characters shown in FIG. This is established as the hiragana character string shown in Figure 9(c).

Next, the character conversion routine shown in block 60 will be explained with reference to the flowchart of FIG. Block 60.10
performs the initial processing of this routine and sets the converted character string index pointer j,=0. In block 60.20, meaningless processing when the fifth character (XsADR+i address) of the converted character string is the same as after conversion is omitted. Block 60.
30, 0 is assigned to the index pointer TP of the character conversion table T shown in FIG. This conversion table T is a table that associates characters generated by switching input character switching keys with respect to one key, and is registered for all keys. In block 60.40, the conversion table T is searched for a character to be converted. When the characters to be converted are alphanumeric characters, they are compared using Ta, when they are hiragana, they are compared using Tb, and when they are katakana, they are compared using Tc. If they do not match, TP is counted up by 1 at block 60.50. In block 60.60, there are characters that cannot be converted when converting to alphanumeric characters (Tl+2.T++a, T+"i*
Tn has no corresponding alphanumeric character and cannot be converted, and FFFF is set in the alphanumeric table. ), check for this presence. In blocks 60 and 70, if conversion is not possible, the return code is set to FFFF (conversion error), and the process is terminated without further conversion. Block 60.80 stores the converted characters in the converted buffer. For example, when converting the hiragana ``ma'' into alphanumeric characters, it becomes r J J. In block 60.90, the converted string index pointer i is incremented by one. Block 60.10
0, it is checked whether all characters have been converted, and X5ADR+ i > XI! It is easy to see that the game ends when it reaches 80+. If the conversion is not completed, jump to block 60.20 and repeat the same process. Block 60.110 sets the return code to O (normal).

As mentioned above, depending on the conversion conditions, you can simply convert one character at a time, or convert it to alphanumeric characters and process it with a character input cursor as if it were entered in Roman alphabet mode to confirm the character. The range of relief can be greatly improved.

〔Effect of the invention〕

As described above, according to the present invention, a character conversion table corresponding to a plurality of types of characters possessed by each of the input keys of a character input device is provided, and characters converted by this table are used as internally generated key inputs. Since the input is made to be re-entered, it is possible to easily correct an incorrect input with a simple bridge construction.
