Abstract

본 발명은 테이프 레코더의 핀치롤러 클리닝 장치를 개시한다.The present invention discloses a pinch roller cleaning apparatus for a tape recorder.

본 발명은, 베이스상에 돌출 설치되며 그 외주면에 경질 탄소막이 코팅된 지지축과; 지지축상에 핀치롤러를 베어링 지지시키며, 핀치롤러를 지지축에 대하여 자동조심 시키는 내경부쉬; 를 포함하여 된 것으로서, 핀치롤러를 내경부쉬를 통해 마찰계수가 작은 경지 탄소막이 코팅된 지지축상에 베어링 지지하는 것이어서, 종래 구름 베어링에 비하여 한층 안정된 핀치롤러의 회전을 도모할 수 있으며, 내경부쉬를 통해 핀치롤러를 캡스턴축상에 평행되게 접촉시킴으로써, 즉, 자동조심시킴으로써, 안정된 테이프의 주행을 도모하여, 화질 및 음질의 향상을 도모할 수 있다. 이에 더하여, 내경부쉬를 사출수지물을 통해 일체로 성형 가능하여 이를 통한 단가절감 및 생산성 향상을 도모할 수 있는 효과가 있다.The present invention includes a support shaft protruding from the base and coated with a hard carbon film on an outer circumferential surface thereof; An inner diameter bush that supports the pinch roller on the support shaft and automatically takes care of the pinch roller with respect to the support shaft; It is to include, the pinch roller is to support the bearing on the support shaft is coated with a hard carbon film having a small coefficient of friction through the inner diameter bush, it is possible to achieve a more stable rotation of the pinch roller than the conventional rolling bearing, By contacting the pinch rollers in parallel on the capstan shaft, i.e., by self-aligning, the stable running of the tape can be achieved, and the image quality and sound quality can be improved. In addition, since the internal diameter bush can be integrally molded through the injection resin, it is possible to reduce the cost and improve productivity.
