Abstract

이 발명은 캠코더나 비데오 테이프 레코더등에 사용되는 상, 하드럼의 갭을 최소한도로 유지하여 고속회전시의 공기의 유입을 차단해서 테이프가 갭사이로 빨려들어가는 것을 방지할 수 있고, 헤드와 로타리 트랜스간의 신호전달체계를 터치타입으로하여 작업능률을 향상시킬 수 있으며, 드럼 내부에서 발생되는 내부정전기를 효율적으로 인출시킬 수 있고, 진동의 방지와 균형의 유지 및 드럼 내부에서 발생되는 자기장의 외부 유출을 방지할 수 있는 테이프 레코더의 드럼장치이다.This invention keeps the gap of hard and rum at minimum used in camcorders and video tape recorders to block the inflow of air during high-speed rotation, thereby preventing the tape from being sucked between the gaps and the signal between the head and the rotary transformer. It can improve the work efficiency by using the touch system as a touch type, can effectively draw out the internal static electricity generated inside the drum, prevent vibration and maintain balance, and prevent external leakage of magnetic field generated inside the drum. It is a drum device of a tape recorder.
