Outputs a signal, and the output basic address signal and characteristic data signal are stored in the latches 3-8, respectively, and the stored basic address signal and characteristic data signal are output control signal LE of the central processing unit 1; And the characteristic data signal is multiplied by the masking characteristic data signals 47Hex and 02Hex through the AND gate group 9-11 and then added to the base address signal by the adder 12-14. That is, the neutral and terminal characteristic data signals output from the latches 7 and 8 are multiplied by 47Hex and the AND gate group 9, and then the adder 12 and the initial basic address signals, which are output signals of the latch 3, are added. The output terminal characteristic data signal of the latch 8 is multiplied by 02Hex and the AND gate group 11 and then added to the output terminal basic address signal of the latch 5 by the adder 14.

In this way, the signals added and output from the adder 12-14 are inputted to the initial, neutral, and final font memory units 15-17, respectively, to designate addresses, and thus the initial, neutral, and final font memory units 15-17. 17) outputs the initial, neutral, and final font images stored in the corresponding address according to the scan signal, and the output font images are transmitted to the video logic through the oragate group 18 to determine the combination characteristics of the initial, neutral, and final characteristics. It prints the corresponding phoneme of Hangul.

The output signal of the adder 12-14, which designates the font address of the initial, neutral, and final font memory 15-17, is expressed by the following equation.

Initial font address = initial base address + 47 Hex & neutral characteristic data & final characteristic data
