Abstract

PURPOSE:To attain the input of all KANA (Japanese syllabary) characters by providing a search key detecting circuit and pushing two search keys in the desired frequency. CONSTITUTION:When the KANA characters are supplied through an alphameric keyboard 11, the vowels and the consonants of Roman characters are set opposite to the KANA characters on the column 'A' of each row. Then the search keys are used as necessary. Thus, all KANA characters can be supplied. When an alphameric key 6 is pushed on the keyboard 11, an alphameric character is supplied to a search key detecting circuit 15 via output lines 111 and 113. Thus, a search key +1 is detected and an output line 115 of the circuit 15 is turned on. As a result, a cursor left shift code generating circuit 17 is actuated to send the cursor left shift codes to a host processor via OR gates 22 and 23 and a bus control line 35. Then a cursor is shifted to the left at a display part 34.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a kana character input method, and particularly to a kana character input method in which kana characters are input using an alphanumeric keyboard without a kana character display.

[Traditional method]

Conventionally, a common method for inputting kana characters is to use a JIS layout kana character keyboard. It is also common to use small keyboards with fewer keys.

[Problems that the invention attempts to solve]

In the above-mentioned conventional kana character input method, the key layout of kana characters on the J-KS layout keyboard is assigned to the keystroke frequency based on the pace, so it is random and it takes a long time to memorize the keystrokes. The disadvantage is that it takes time to enter characters that are used infrequently, searching for the appropriate character each time. In addition, small keyboards have a small number of keys and cannot be arranged in a J/S layout or a 50-note layout, so each keyboard often has a special key layout, which takes a long time to memorize. There was a drawback that even if I memorized it, I could not use it for anything else.

[Means for solving problems]

The kana character input method of the present invention includes an alphanumeric keyboard for inputting alphanumeric characters, an input mode selection circuit for selecting a mode for converting input from the alphanumeric keyboard from alphanumeric code to kana character code, and the input mode selection circuit. A kana character code generation circuit that generates a kana character code corresponding to an alphanumeric key on an alphanumeric keyboard when the kana character mode is selected in the circuit, and a kana character code that holds the output kana character code of the kana character code generation circuit. It is operated by the output of the character code register, the search key bI2 output circuit that outputs a search key that modifies the kana character code output from the kana character code register, and the boucher detection 1g circuit, and the output of the kana character code register. A kana character code modification circuit that modifies the output kana X-character code according to the instructions of the detected search key, a cursor left movement code generation circuit that generates a code that moves the cursor to the left, and a control code that passes the control code. a passage circuit, and the corrected kana-mata-ji code output from the kana-character code correction circuit is held in the kana-character code register together with the kana-character code on the back of the mountain of the kana-character code generation circuit! has been completed.
