Abstract

PURPOSE:To shorten a read and a write time for lateral characteristics by reading the dot pattern of each character as blocks obtained by dividing the pattern longitudinally and laterally by a prescribed number by a processor for character pattern information consisting of dots. CONSTITUTION:The figure shows an example of the block division of a character pattern, and a pattern having 32 dots longitudinally and laterally is divided into 16 blocks each having 8 dots longitudinally and laterally, i.e., 64 dots in total. A CG memory stored with this dot pattern is addressed, block by block, and pattern data of 64 dots from a row 0- a row 7 included in one block is read by attaining access once. An erected character is read in the order of blocks 0, 1- 14, and 15, and for longitudinal-lateral conversion, its is read in the order of blocks 3- 15, 2- 14, 1- 13, and 0- 12. In either case of the erected character and longitudinal-lateral conversion, CG memory access is attained only four times, speeding the operation.
