Abstract
Description
Claims (4)
- 헤드드럼 구동을 위한 모우터와 자기테이프구동을 위한 모우터를 가지며, 두개의 모우터의 속도조절과 위상조절을 위한 전자장치를 가지며, 영상탐색주행구동을 위해 재생키를 작동할 때 전진 및 후진 방향을 정하는데 사용할 수 있는 두개의 작동키를 가진 비디오 레코더에 있어서, 재생구동시 테이프 구동모우터(28)의 속도가 적분기(27)에서 나온 교정전압에 의해 변화되며, 이 적분기는 시스템표준에 의해 속도가 고정될 경우 위상에러전압을 적분하고 위상에러가 고정적으로 미리 주어질 때는 교정전압을 나오게 하는 것을 특징으로 하는 비디오 레코더.
- 제 1 항에 있어서, 영상탐색주행구동시 적분기(27)가 차단될 수 있는 것을 특징으로 하는 비디오 레코더.
- 제 1 항에 있어서, 영상탐색주행구동시 적분기(27)가 접속되고, 테이프속도가 변화하는 동안 교정전압의 출력은 "영"으로 되며 주어진 시간작동이 후에 위상에러에 의해 얻어진 값으로 증가되는 것을 특징으로 하는 비디오 레코더.
- 제1 및 제 3 항에 있어서, 영상탐색주행구동시 적분기(27)는 위상측정임펄스가 에러를 가질 경우 최후의 적분값을 유지하고 있는 것을 특징으로 하는 비디오 레코더.
