도트 메트릭스 프린터에서의 캐리지 구동방법Carriage driving method in dot matrix printer

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명 방법의 플로우 챠트, 제2도는 본 발명 방법을 설명하기 위한 캐리지 구동 장치의 블록 구성도, 제3도는 캐리지 구동 속도를 나타낸 도표.1 is a flowchart of a method of the present invention, FIG. 2 is a block diagram of a carriage driving apparatus for explaining the method of the present invention, and FIG. 3 is a diagram showing a carriage driving speed.

Claims (1)

CPU(1)에서 영상 버퍼용 RAM(2)내의 공간을 모우터(M)의 스텝수로 변환시킨 다음 데이타내의 문자사이의 스텝수들이 모우터의 (가속+감속)스텝수의 2배보다 큰가를 검출하여 크지 않으면 원래의 속도를 유지하면서 다음의 인자 위치로 캐리지를 이동시켜 인자하고, 큰 경우에는 앞 문자를 인자한 다음 감속시킨후〔공간-(감속+가속)〕스텝수 만큼 모우터를 빠른 속도로 동작시켜 인자를 수행한 후 크지 않을때와 마찬가지로 영상 버퍼내의 인자할 어드레스가 최종 어드레스인가를 검출하는 제1과정과, 상기 제1과정에서 최종 어드레스가 아니면 제1과정중 데이타 내의 문자사이의 스텝수들이 모우터의 (가속+감속)스텝수의 2배보다 큰가를 검출하는 과정으로 되돌아가되 최종 어드레스이면 모우터를 감속 스텝만큼 감속시킨후 종료하는 제2과정으로 이루어짐을 특징으로 하는 도트 메트릭스 프린터에서의 캐리지 구동방법.The CPU 1 converts the space in the image buffer RAM 2 to the number of steps of the motor M, and then the number of steps between characters in the data is greater than twice the number of (acceleration + deceleration) steps of the motor. If it is not large, move the carriage to the next printing position while maintaining the original speed, and if it is large, print the previous character, decelerate it, and decelerate the motor by the number of [space- (deceleration + acceleration)] steps. The first step of detecting whether the address to be printed in the image buffer is the final address as in the case of not being large after performing the printing by operating at a speed, and between the characters in the data in the first process if the address is not the last address in the first step The process returns to detecting whether the number of steps is greater than twice the number of (acceleration + deceleration) steps of the motor, but if the final address, the second step of decelerating the motor by the deceleration step and ending the process. Carriage driving method in a dot matrix printer, characterized in that. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
