Abstract

본 발명은 테이프 레코더의 테이프 위치 보정 방법에 관한 것으로, 특히 에스 릴 센서를 이용하여 전원 온/오프(ON/OFF) 시의 테이프의 위치 차이 발생을 보정하는 테이프 레코더의 테이프 위치 보정 방법에 관한 것으로, 재생 또는 녹화 상태에서 전원이 오프되면 로우딩 모터와 캡스턴 모터를 역회전시키고 언로우딩이 완료되면 상기 로우딩 모터와 캡스턴 모터를 정지시키는 언로우딩 단계, 상기 언로우딩 단계에서 공급 릴의 회전에 의해 발생되는 제1릴 펄스를 감지하여 카운트하는 제1릴 펄스 카운트 단계, 전원이 온되고 재생 명령 또는 녹화 명령이 입력되면 상기 로우딩 모터를 회전시켜 로우딩을 완료하는 로우딩 단계, 상기 로우딩 단계에서 공급 릴이 풀림에 따라 발생되는 제2 릴 펄스를 감지하여 카운트하는 제2릴 펄스 카운트 단계, 및 상기 카운트된 제1 및 제2 릴 펄스의 차만큼 상기 캡스턴 모터를 회전시킨 후 재생 또는 녹화를 수행하는 캡스턴 모터 회전 단계를 포함하여 수행된다.The present invention relates to a tape position correction method of a tape recorder, and more particularly, to a tape position correction method of a tape recorder for correcting a position difference of a tape when power is turned on / off by using an reel sensor. When the power is turned off in the playback or recording state, the unloading step of rotating the loading motor and the capstan motor and stopping the loading motor and the capstan motor when the unloading is completed; A first reel pulse counting step of detecting and counting a first reel pulse generated by rotation; a loading step of completing the loading by rotating the loading motor when power is turned on and a play command or a recording command is input; A second reel pulse count step of detecting and counting a second reel pulse generated as the supply reel is released in the loading step, and the car Committed by the first and the difference between the two reel pulse is carried out, including a capstan motor rotating step of performing the after rotating the capstan motor playback or recording.

따라서 본 발명은 테이프의 위치 차이가 1개의 릴 펄스 정도 밖에 발생되지 않아 재생 또는 녹화 화면의 연결 차이가 대폭 수정되는 효과가 있다.Therefore, in the present invention, since the position difference of the tape is generated only one reel pulse, the connection difference of the playback or recording screen is greatly corrected.
