ABSTRACT:
In order to reduce the capacity of a character ROM without reducing the character information, n-bit bit pattern data and sequence data having information necessary for composing n-bit m components are stored in first memory means (character ROM). Second memory means has addresses corresponding to each display position on the screen and holds addresses for the first memory means as a data. In accordance with the address from the second memory means and the sequence data from the first memory means, address modifying means produces an address of a scanning line with respect to pertinent character for the first memory means. According to this address, the bit pattern data is read out from the first memory means.
