ABSTRACT:
A font pattern to be stored is created by sequentially forming exclusive logical sums neighboring first bit patterns A1-A20 to form a plurality of second neighboring bit patterns B1-B20; designating at least one or more than one bit pattern which appears most frequently in the plurality of second bit patterns as a reference bit pattern, comprising and storing the difference of each bit pattern of the plurality of second bit patterns and the reference bit pattern per each bit pattern, and storing only the bit patterns which differ from the reference bit pattern in the plurality of second bit patterns.
