Abstract
A character code generating device includes a standard character code correspondence table for storing the character codes each corresponding to individual key-inputs from a key board, a searching device for the for said standard character code correspondence table to generate the character codes corresponding to the key-inputs, a supplementary character code correspondence table and a judging device. The supplementary character code correspondence table serves to store the character codes different from those in the standard character code correspondence table with respect to the specified key-inputs from the key board. The judging device determines whether the search of the supplementary character code correspondence table is required or not. Upon a determination relative to the search of the supplementary character code correspondence table by the judging devices, the searching devices operates to preferentially search the supplementary character code correspondence table prior to the standard character code correspondence table.
