Abstract

PURPOSE:To improve the operability of the character input key of the title device by displaying the character of a preset mode in a table when a 1st key is operated and converting the characters into those of another mode and displaying the converted characters by referring to the table when a 2nd key is operated in such display state. CONSTITUTION:When character input keys 11a on a keyboard 11 are successively operated, character data of the mode previously selected through a mode selection key are successively accumulated in a character string accumulator 13. A display device 16 displays the character string of the character string data accumulated in the accumulator 13. When an operator successively operates the keys 11a after he erroneously sets Roman character input mode in the case of inputting, for example, a KANA (Japanese syllabary) character string in such state, a Roman character string is inputted and displayed. When a mode change key 12 is operated in such display state, the KANA character string is displayed after Roman character string is converted into the KANA character. Therefore, it is not required by the operator to input the KANA character string again after erasing the Roman character string.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a character input system used in computers, word processors, and the like.

2. Description of the Related Art Conventionally, this type of character input device has a character input key in which both English characters and kana characters are assigned to one key, and a key for selecting the character input mode of that key. The apparatus has a keyboard equipped with a keyboard, and when a character input key of this keyboard is operated, it is configured to be processed as a character of a mode specified in advance by a mode selection key.

Therefore, the operator can selectively input English characters, etc. or kana characters by operating the character input key after operating the mode selection key. In conventional character input devices, when a character input key on a keyboard is operated, it is processed as a character in the mode specified by the mode selection key in advance, so if the operator mistakenly operates the 1st selection key and inputs a character, You will be entering undesired characters and therefore
The operator must erase the input characters, select the desired character mode, and operate the character entry keys again.

There is a problem that operation is troublesome.

In particular, when inputting a kana character string mixed with English characters, it is necessary to switch the mode, and all operations on incorrectly input characters due to neglecting to switch the mode will be wasted.

In view of the above-mentioned conventional problems, an object of the present invention is to provide a character input device that can improve the operability of character input keys in which both English characters and kana characters are assigned to one key. shall be.

Means for Solving the Problems In order to achieve the above object, the present invention provides, in addition to a first key to which both kana characters and English characters are assigned, characters inputted through this first key. A second key is provided for inputting a command to convert the text into another character mode, and a table is provided in which the data of both characters assigned to the first key are stored in correspondence. In the event that
The relevant character in a preset mode is displayed, and when the second key is operated in this display state, the table is referred to and the character is converted into a character in another mode and displayed.

Effect: With the above configuration, even if the operator selects the wrong character mode and inputs a character, there is no need to erase the character and re-enter the desired character.
It is possible to improve the operability of character input keys in which both English characters and kana characters are assigned to each key.

EXAMPLES Hereinafter, the present invention will be described in detail with reference to the drawings. The diagram is
FIG. 1 is a functional block diagram showing an embodiment of a character input device according to the present invention.

In the figure, 11 represents, for example, the kana character "ki" and the English character "G" as defined in JIS (Japanese Industrial Standards).
, the kana character "yo" and the symbol ")", the kana character "tsu" and the number "4", the kana character "no" and the English letter "K", the kana character "te" and the English letter "W", the kana character " Character input key 11a to which the English letter ``Y'' and the English letter ``Y'', the kana character ``ki'' and the English letter ``G'' are respectively assigned, and the characters entered through this character input key 118 to other characters. The keyboard is equipped with a mode conversion key 12 for inputting a command to convert to the mode, a mode selection key (not shown) for selecting the character input mode of the character input key 11a, and the like.

Note that the mode conversion key 12 and the mode selection key may also be used.

13 is a character string accumulator for accumulating data of character strings (before kana-kanji conversion) input via the character input key 11a of the keyboard 11; 14 is a character string accumulated in the character string accumulator 13; A character string converter 15 converts data into character string data in other modes and replaces data in the character string accumulator 13, and 15 represents kana character data, English character data, etc. assigned to the character input key 11a of the keyboard 11. A character correspondence table 16 in which are stored in correspondence with each other is a display device that displays character strings of character string data stored in the character string storage 13.

Next, the operation of the above embodiment will be explained.

In the figure, when the character input keys 113 of the keyboard 11 are sequentially operated, the character data of the mode selected in advance by the mode selection key is sequentially stored in the character string accumulator 13, and the display device 16 displays this character string. The character string of the character string data stored in the accumulator 13 is displayed.

In this state, when the mode conversion key 12 of the keyboard 11 is operated, the one-character string converter 14 reads out each character data stored in the character string accumulator 13, refers to the character correspondence table 15, and selects another mode. is converted into character string data and replaces the data in the one character string accumulator 13.

Therefore, the first input character string is converted into a character string in another mode and displayed on the first display device 16.

That is, when the operator inputs the kana character string "Kiyou no Tenki", for example, if the operator mistakenly sets the English character input mode and operates the corresponding character input keys 11a sequentially, the English character string r
G) 4KWYGJ is input and displayed, but if the mode conversion key 12 is operated in this display state, the kana character string "
Since it is converted to "Kyo no Tenki" and displayed, the operator does not need to delete the first input English character string "1G)4KWYG" and enter the kana character string "Kyo no Tenki" again. When an operator inputs a kana character string mixed with English characters, etc., it is necessary to switch the mode, but the operation of characters input incorrectly by neglecting to switch the mode is not wasted.

DETAILED DESCRIPTION OF THE INVENTION As described above, the present invention provides, in addition to a first key to which both kana characters and English characters are assigned, characters input via this first key to other character modes. A second key for inputting a command to convert into , and a table in which data of both characters assigned to the first key are stored in correspondence are provided, and when the first key is operated, The character in the preset mode is displayed, and when the second key is operated in this display state, the table is referred to and the character is converted to the character in another mode and displayed. Even if a user selects the wrong character mode and enters a character, there is no need to erase that character and re-enter the desired character; therefore, both English characters and kana characters are assigned to one key. The operability of character input keys can be improved.
