Abstract

본 발명은 테이프의 시작과 끝을 검출하기 위한 회로를 공개한다. 그 회로는 센서 출력신호를 입력하여 센서 신호를 발생하기 위한 센서 신호 발생수단, 상기 센서 신호 발생수단의 출력신호를 입력하여 기준 비교전압을 발생하기 위한 기준 비교전압 발생수단, 및 상기 센서 신호 발생수단의 출력신호와 기준 비교전압 발생수단의 출력신호를 입력하여 시작과 끝을 검출하기 위한 신호를 출력하기 위한 비교수단으로 구성되어 있다. 따라서 센서 출력신호만을 사용하여 테이프의 시작과 끝을 검출할 수 있다.The present invention discloses a circuit for detecting the start and end of a tape. The circuit includes sensor signal generating means for inputting a sensor output signal to generate a sensor signal, reference comparison voltage generating means for inputting an output signal of the sensor signal generating means to generate a reference comparison voltage, and the sensor signal generating means. And a comparison means for outputting a signal for detecting the start and the end by inputting an output signal of the reference signal and an output signal of the reference comparison voltage generating means. Therefore, the start and end of the tape can be detected using only the sensor output signal.
