JAPANESE INPUT DEVICE, ELECTRONIC EQUIPMENT HAVING JAPANESE INPUT PART, AND MEDIUM RECORDING JAPANESE INPUT CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a Japanese input device suitably used for inputting Japanese words while reducing the number of input keys without increasing input work and complicating selection, an electronic equipment having Japanese input part, and a medium recording Japanese input control program. SOLUTION: In a step S41, the utilization frequency of KANA characters registered on the indexes of a KANJI dictionary is summed up and in a step S42, the utilization frequency of Correspondent English characters for inputting respective KANA characters is calculated so that the utilization frequency concerning the English characters as Japanese input elements can be discriminated. In a step S43, the English characters of high utilization frequency are singly allocated to the input keys so that the higher the utilization frequency is, the less the KANA characters generated by a character generating means can not be generated while being overlapped when inputting Japanese words while utilizing such an input means. Thus, KANJI candidates to be generated by a KANJI mixed character string generating means while referring to the indexes of the dictionary can be reduced.
