Abstract

PURPOSE: To simplify the circuit constitution by sharing the read address indication circuit, the write address indication circuit and the switch circuit to the pattern memory and the ruling memory and avoiding the overlap of the circuits.
CONSTITUTION: Pattern memory 24 to memorize the picture pattern of the characters or the like is installed, along with IC memory 12 to memorize the ruling pattern. And the picture pattern and the ruling pattern are read out from memory 24 and 12 in synchronization and then displayed on CRT. In such device, read address designation circuit 22 and write address designation circuit 10 are installed. In addition, divider 21 to generate the pulse synchronized with the CRT scan is provided along with switch circuit 23 to switch and select the addresses given from circuit 22 and 10. Thus, the circuit constitution can be simplified by avoiding the overlap of the circuits.
