Abstract

본 발명은 자기기록재생기의 테이프 텐션 제어장치에 관한 것으로, 베이스 플레이트(1)에 고정된 축(36')에 일단부가 축착되고 캠기어(15)에 연동되어 모드 변환시 텐션 암(31)의 위치를 가변시키는 텐션 조절암(36)과, 상기 텐션 암(31)과 텐션 조절암(36)간에 연결되는 스프링(35)과, 공급릴 테이블(10)의 외주면에 권회되고 양단부가 상기 텐션 암(31)과 텐션 조절암(36)에 연결되는 텐션 밴드(34)로 구성되어 있으며, 상기 텐션 암(71)의 축(71')이 인쇄회로기판(60)에 고정되는 엔드 센서 홀더(61)에 일체로 형성되는 축 지지부(61a)에 삽입 지지된 구성으로 되어 있다. 이러한 본 발명은 텐션암 탄지용 스프링 및 텐션 밴드의 길이를 각 모드에 따라 적정한 량만큼 가변하여 텐션을 적정하게 조절할 수 있으며, 특히 재생 모드에서 리뷰 및 역 슬로우로 모드 변환시 테이프의 늘어짐을 조절할 수 있어 화면 노이즈(noise)를 개선할 수 있으며, 텐션 암의 축을 지지하기 위한 사용 부품수를 절감하고 작업불량을 해소할 수 있게 되는 이점이 있다.The present invention relates to a tape tension control apparatus of a magnetic recording and reproducing apparatus, wherein one end is fixed to a shaft (36 ') fixed to the base plate (1) and the position of the tension arm (31) when the mode is switched in conjunction with the cam gear (15). A tension adjusting arm 36 for varying the spring, a spring 35 connected between the tension arm 31 and the tension adjusting arm 36, and an outer circumferential surface of the supply reel table 10, and both ends thereof are wound around the tension arm ( 31) and a tension band 34 connected to the tension adjusting arm 36, and the end sensor holder 61 of which the shaft 71 'of the tension arm 71 is fixed to the printed circuit board 60. It is the structure inserted and supported by the axial support part 61a integrally formed in the inside. The present invention can adjust the tension appropriately by varying the length of the tension arm finger spring and the tension band according to each mode, and in particular, in the playback mode can be adjusted to the sagging of the tape when the mode conversion to review and reverse slow The screen noise can be improved, and the number of parts used to support the axis of the tension arm can be reduced and the work defect can be eliminated.
