Description

인자데이타 유무에 따른 전원자동 온·오프 제어방법Automatic power on / off control method depending on printing data

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

Claims (1)

호스트머신(1)에서 출력되는 데이타 스트로브신호()가 중앙처리장치(4)에 입력되었을 경우에 중앙처리장치(4)는 엔드오브화일 플래그가 세트되어 있는지를 판별하고 이때 세트되었을 경우에는 중앙처리장치(4)는 출력포트(PO1-PO3)로 고전위신호를 출력하여 캐리지 및 피드, 인자구동부(7-9)에 전원부(10)의 동작전원(Va-Vc)이 인가되게 하고, 상기에서 엔드오브화일이 세트되어 있지 않을 경우와 동일하게 프로그램롬(5) 및 램(6)에 저장된 데이타를 읽은 후 그 읽은 데이타가 그 화일의 마지막 코드 즉, 엔드오브화일코드인가를 판별하여 엔드오브화일 코드가 아닐경우에는 상기에서 읽은 데이타를 처러하기 위해 데이타 루틴을 수행하고, 엔드오브화일 코드일 경우에는 엔드오브화일 플래그를 세트시키고, 중앙처리장치(4)는 출력포트(PO1-PO3)로 저전위신호를 출력하여 캐리지 및 피드, 인자구동부(7-9)에 인가되는 전원부(10)의 동작전원(Va-Vc)이 차단되게 제어함을 특징으로 하는 인자데이타 유무에 따른 전원자동 온·오프 제어방법.Data strobe signal output from the host machine (1) Is input to the central processing unit 4, the central processing unit 4 determines whether the end-of-file flag is set, and if this is set, the central processing unit 4 outputs the output port (PO 1 -PO). 3 ) outputs a high potential signal so that the operating power (V a- V c ) of the power supply unit 10 is applied to the carriage, feed, and print driver 7-9, and the end-of-file is not set. As in the case, after reading the data stored in the program ROM 5 and the RAM 6, it is determined whether the read data is the last code of the file, that is, the end of file code. The data routine is executed to process data, and in the case of an end-of-file code, the end-of-file flag is set, and the central processing unit 4 outputs a low potential signal to the output ports PO 1 -PO 3 to carry a carriage. And feed, printing driver (7-9) Operation of the power supply unit is 10, which is the power (V a -V c) is to be controlled also features methods automatic power on-off control according to the parameter data according to whether or not blocked. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
