도트 매트릭스 프린터에 있어서, 중앙 처리 장치(10)중의 연산 장치(10A) 내의 A 레지스터에 폰트 롬(20)의 인자 하고자 하는 어드레스 값(ADRL)을 삽입하고, 이 어드레스를 내부 어드레스/데이타 버스를 통하여 전송하여 어드레스 버퍼(10D)에 A 레지스터의 내용을 적재하고, 상기 연산 장치(10A)에서 어드레스 라인(ADRL)을 인에이블 시켜주면 폰트 롬(20)의 인자 하고자 하는 어드레스가 연결 되도록 하고, 읽기/써넣기 신호()를 하이 액티브 상태로 하여 해당 어드레스에 속하는 데이타가 데이타 버스를 통하여 중앙 처리 장치(10)내의 데이타 버퍼(10C)에 배치하고, 이와 같이 데이타 버퍼(10C)에 래치된 상태에서 A 레지스터에 램(30A),(30B)으로부터의 저장하고자 하는 어드레스 값을 삽입하고 어드레스 버퍼(10D)에 저장 시킨후에 어드레스 라인을 인에이블 시켜 읽기/써넣기 신호()를 로우 액티브 상태로 하여 데이타 버퍼(10C)의 내용이 램(30A),(30B)에 저장하며, 상기에서와 같은 상태를 72회 반복하여 폰트 롬(20)의 내용이 램(30A),(30B)에 그대로 저장되도록 하고, 상기 램(30A),(30B)에 저장된 데이타를 첫번째 어드레스로부터 재차 중앙처리장치(10)중의 연산장치(10A)내의 D레지스터에 적재하여 4단계로 오어링(Oring)의 값을 변경 시키는 순서적인 임의의 값과 오어링하여 출력되는 값을 재차 상기 램(30A),(30B)내부에 저장하는 과정으로 이루어 지는 도트 매트릭스 프린터에서의 음영 문자의 인자 방식.In the dot matrix printer, an address value ADRL to be printed of the font ROM 20 is inserted into an A register in the arithmetic unit 10A of the central processing unit 10, and this address is transmitted through an internal address / data bus. By transferring and loading the contents of the A register into the address buffer 10D, and enabling the address line ADRL in the arithmetic unit 10A, the address to be printed in the font ROM 20 is connected and read / read. Write signal ( ), The data belonging to the address is placed in the data buffer 10C in the central processing unit 10 via the data bus, and thus RAM (in the A register) is latched in the data buffer 10C. After inserting the address values to be stored from 30A) and 30B and storing them in the address buffer 10D, the address lines are enabled to read / write signals ( ), The contents of the data buffer 10C are stored in the RAMs 30A and 30B, and the same state as described above is repeated 72 times so that the contents of the font ROM 20 are changed to the RAM 30A, The data stored in the RAMs 30A and 30B are loaded into the D register in the processing unit 10A in the central processing unit 10 again from the first address. A printing method of a shadow character in a dot matrix printer, which is performed by storing an ordered random value for changing a value of Oring) and a value that is output by ordering the inside of the RAMs 30A and 30B. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
