Claims (1)

키보드(1)의 버튼을 누름에 따라 키 매트릭스(2)에서 발생된 정보신호를 키 마이크로 프로세서(3)에서 받아들여 그에 대응하는 데이타를 인터페이스회로(6)를 통하여 매인 마이크로 프로세서(7)에 인가하고, 롬(8)의 프로그램 내용에 의해 상기 데이타를 매인 마이크로 프로세서(7)에서 받아들인 후 라인버퍼 메모리(9a)에 순차적으로 저장함과 아울러 그 저장 데이타에 해당되는 문자를 LCD구동회로(10)를 통하여 LCD(11)에 좌측으로부터 순차적으로 표시하되, 그 라인버퍼메모리(9a)에 데이타가 모두 저장된 경우에는 그 저장된 데이타를 순차적으로 1자씩 이동시켜 램(9)에 기억시키면서 새로운 데이타를 저장함과 아울러 LCD(11)의 표시문자도 좌측으로 1자씩 순차적으로 이동시켜 표시하고, 상기 라인버퍼메모리(9a)에 데이타가 저장될 때 및 커서의 좌.우이동시에 클러치 구동회로(14)로 클로치(15)를 온시켜 스텝모터(13)를 헤드 이송장치(17)에 연결함과 아울러 스텝모터 구동회로(12)로 스텝모터(13)를 구동시켜 헤드를 이송시키게 하며, 라인 변환 및 커서의 상.하 이동시에 클러치 구동회로(14)로 클러치(15)를 오프시켜 스텝모터(13)를 용지이송장치(18)에 연결함과 아울러 스텝모터 구동회로(12)로 스텝모터(13)를 구동시켜 용지를 이송시키게 함을 특징으로 하는 프린트 겸용 타자기의 간이 편집방식.By pressing the button of the keyboard 1, the information signal generated in the key matrix 2 is received by the key microprocessor 3 and the corresponding data is applied to the main microprocessor 7 via the interface circuit 6. After receiving the data from the main microprocessor 7 according to the program contents of the ROM 8, the data is sequentially stored in the line buffer memory 9a, and the characters corresponding to the stored data are stored in the LCD driving circuit 10. In order to display sequentially from the left side on the LCD (11) through, if all the data is stored in the line buffer memory (9a) to store the new data while moving the stored data one by one sequentially in the RAM (9) and In addition, the display characters of the LCD 11 are also displayed one by one to the left in order, and when data is stored in the line buffer memory 9a and when the cursor moves left and right. The clutch drive circuit 14 turns on the clutch 15 to connect the step motor 13 to the head feeder 17, and the step motor drive circuit 12 drives the step motor 13 to drive the head. The clutch 15 is turned off by the clutch driving circuit 14 when the line is changed and the cursor moves up and down, and the step motor 13 is connected to the paper feeder 18, and the step motor driving circuit ( 12) A simple editing method of a print typewriter, characterized in that to drive the step motor 13 to convey the paper. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
