Description

CCD의 광원으로 이용되는 형광등의 정상동작 판단방식Normal operation judgment method of fluorescent lamp used as CCD light source

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

제2도는 본 발명의 리딩(Reading)부의 블럭구성도2 is a block diagram of a reading part of the present invention.

Claims (1)

화상스캐닝 장치에 있어서, 송신을 시작하는 시점에서 형광등을 점등시키고, 원고를 리딩위치센서(3)까지 이동시킨 다음에 1라인백신호 검출회로(10)로 부터 입력되는 신호를 확인한 후에 1라인이 모두 백이라는 신호가 입력 될때까지 대기하고, 이어서, 정해진 라인 이상의 라인이 모두 백인것이 판단되면 그때까지의 원고(2)를 실제의 리딩위치까지 미동시키고 원고를 읽기 시작한 다음에, 만일 일정시간까지 1라인이 모두 백이라는 신호가 입력되지 않으면 송신을 중단하고 형광등(4)에 이상이 발생되었음을 알라는 알람신호를 발하도록 하는 과정으로 이루어지는 CCD의 광원으로 이용되는 형광등의 정상동작 판단방식.In the image scanning apparatus, a fluorescent lamp is turned on at the start of transmission, the original is moved to the reading position sensor 3, and after checking the signal input from the one-line back signal detection circuit 10, all one line is finished. Wait until the signal of white is input, and then, if it is determined that all the lines above the designated line are all white, the original document 2 is moved to the actual reading position until the actual reading position is started, and after reading the original, one line by a certain time If all of the white signal is not input, the transmission is stopped and the fluorescent lamp (4) is a normal operation method of the fluorescent lamp used as the light source of the CCD consisting of the alarm signal to inform that the occurrence of an error. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
