Abstract

본 발명은 음극선관용 편향장치에 관한 것으로, 이는 두쌍의 코일을 편향요크에 서로 대칭적으로 위치시켜 그 코일의 사이각도를 자유롭게 변화시키고 그 변화된 사이각도에 의해 R빔을 상대적인 편향량을 줄여 미스콘버젼스 및 코마수차를 보정하도록 하기 위한 것이다.The present invention relates to a deflection apparatus for a cathode ray tube, in which two pairs of coils are placed symmetrically on a deflection yoke to freely change the angle between the coils and reduce the relative deflection of the R beam by the changed angle. To correct the version and coma aberration.
