Abstract
PURPOSE: To ensure a highly efficient control for the memory means which memorizes the patterns of the characters and the like by using the count-up output of the counter as the address and then applying the ouput in sequence to the memory means.
CONSTITUTION: In case the character or the pattern is taken out of ROM1, input means 2 is operated to deliver the binary number code corresponding to the fixed character to the signal line. And the binary number code is drawn into 1st register 32 of CPU5 to be given N-multiplication. This value of N is corresponding to the word number one character or pattern occupies within ROM1. Thus the binary code given from means 2 has correspndence to the actual head address of ROM1 by the multiplication operation. And the effective head address of ROM1 is drawn into counter means 4. As the output of means 4 is connected to the address signal line of ROM1, the head address of the ROM is addressed. The above action is given in sequence to N units of the reading pulse given from the CPU, and as a result, one character or pattern within the ROM is read out.
