테이프 레코더 헤드의 이물질 제거장치Debris Removal Device for Tape Recorder Head

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

첨부된 도면은 본 발명에 따른 테이프레코더 헤드의 이물질 제거장치에 대한 블록다이어그램이다.The accompanying drawings are block diagrams of the foreign material removing apparatus of the tape recorder head according to the present invention.

Claims (1)

헤드에 묻은 이물질을 제거하기 위한 헤드크리너를 구비한 테이프레코더 헤드의 이물질 제거장치에 있어서; 상기의 헤드에 묻은 이물질을 감지하여 증폭하기 위한 이물질 검출수단; 비디오 테이프에 기록된 제어신호를 감지하여 테이프의 재생상태를 판단하기 위한 제어신호 판별수단; 상기의 제어신호 판별수단에서 출력된 신호에 의해 동작하여 상기의 이물질 검출수단의 출력신호를 샘플링하기 위한 포락션 검출수단; 상기 샘플링된 아날로그 신호를 디지틀신호로 변환시키기 위한 아날로그/디지틀 변환수단; 상기의 디지틀신호를 소정의 기준신호와 비교하여 헤드의 이물질을 검출하되, 상기의 디지틀 신호가 기준신호보다 클 경우에는 재생시 상기의 헤드에 이물질이 없음을 표시하는 신호를 발생하고, 상기의 디지틀신호가 기준신호보다 작을 경우에는 헤드에 이물질이 있음을 표시하는 신호를 발생하기 위한 비교수단 및; 상기의 비교수단에서 출력되는 신호를 입력으로하여 상기의 헤드크리너를 작동시키기 위한 헤드크리너 구동수단으로 구성시켜서 됨을 특징으로 하는 하나 테이프레코더 헤드의 이물질 제거장치.An apparatus for removing foreign substances in a tape recorder head having a head cleaner for removing foreign substances from a head; Foreign matter detection means for detecting and amplifying foreign matter on the head; Control signal determination means for detecting a control signal recorded on the video tape to determine a playback state of the tape; Enclosure detection means for operating by the signal output from the control signal determination means for sampling the output signal of the foreign matter detection means; Analog / digital conversion means for converting the sampled analog signal into a digital signal; The foreign material of the head is detected by comparing the digital signal with a predetermined reference signal, and when the digital signal is larger than the reference signal, a signal indicating that there is no foreign material in the head is generated during playback, and the digital Comparing means for generating a signal indicating that there is a foreign object in the head when the signal is smaller than the reference signal; The foreign material removal apparatus of one of the tape recorder head, characterized in that configured as a head cleaner driving means for operating the head cleaner by inputting the signal output from the comparison means. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
