Abstract

PURPOSE: To increase the feeicienct of generation of characters by giving access to a character generator by the use of an address obtained by operation of the output of converted address and raster counter.
CONSTITUTION: Character generator 30 stores dot patterns of indication characters, each of which is converted into the address to be fixed temposrally, by address coverting circuit 10, and operational circuit 20 makes an address of character generator 30 by means of the converted address and the address indication aline or a column. Namely, the efficiency of generation of characters can be increased by giving access to character generator 30 indirectly by the use of the address obtained by operation of the output of the converted address and raster counter.
