Abstract

본 발명은 VCR의 헤드드럼장치에 관한 것으로, 메인베이스의 상면에 일정한 기울기로 고정·설치되는 드럼베이스와, 상기 드럼베이스의 상부에 동일한 기울기로 고정·장착된 하부드럼과, 상기 하부드럼의 상부에 회동 강하게 조립되며, 그 하단의 소정 위치에 비디오헤드가 설치된 상부드럼과, 상기 드럼베이스의 하부에 설치되며, 그 중심에는 상기 하부드럼을 관통하여 상부드럼에 압입되는 드럼샤프트가 고정·설치된 드럼모터로 이루어지는 VCR의 헤드드럼장치에 있어서, 상기 상부드럼의 저면 가장자리에 원통형의 리드플랜지의 상단이 고정·장착된 상태에서 그 하단이 상기 하부드럼의 내부에 삽입되고, 상기 하부드럼의 상단면은 통상의 테이프주행면의 경사도와 동일한 기울기로 형성되며, 상기 리드플랜지의 하단과 상기 하부드럼의 상면 사이에는 소정간격의 바람유출통로가 형성되도록 하므로써 테이프가 주행되는 과정에서 상부드럼과 하부드럼사이에 형성되는 조립틈새로 흡인되는 현상이 효과적으로 방지되도록 하므로써 테이프의 기록면이 손상되는 것을 미연에 방지할 수 있도록 한 것이다.The present invention relates to a head drum device of a VCR, comprising: a drum base fixed and installed on a top surface of a main base at a predetermined slope, a lower drum fixed and mounted at a same slope on an upper portion of the drum base, and an upper portion of the lower drum; A drum which is strongly assembled on the drum, and which is provided with an upper drum having a video head at a predetermined position at the lower end thereof, and a drum shaft fixed at the lower part of the drum base, the drum shaft being pushed into the upper drum through the lower drum at its center; In the head drum device of a VCR made of a motor, the lower end is inserted into the lower drum while the upper end of the cylindrical lead flange is fixed to the bottom edge of the upper drum, and the upper end of the lower drum is It is formed with the same inclination of the normal tape running surface, between the lower end of the lead flange and the upper surface of the lower drum In order to prevent the damage of the recording surface of the tape, it is possible to effectively prevent the suction of the assembly gap formed between the upper drum and the lower drum in the process of running the tape by forming a wind flow passage with a predetermined interval. It is.
