The character generator stores bit patterns for forming a part of dot matrix data based on a specific rule applied to a plurality of font pattern. During regeneration of the font patterns, a whole configuration of the font patterns is automatically regenerated based on the bit patterns for forming a part of the dot matrix data based on the specific rule which have been stored in the character generator.
