あった。(b) Conventional technology Conventionally, a saddle-shaped horizontal deflection coil and a toroidal core generate magnetic fields as shown in Figures 5 (a) and (b), respectively. It may cause distortion. In the figure, (1) is a horizontal deflection coil, (2) is a vertical deflection coil, and (3) is a toroidal core. The above raster distortion is conventionally
Correction was performed using the method shown in Publication No. 1248, etc., but with the conventional method, if the bink tension tendency of vertical raster distortion is larger than that of horizontal raster distortion, correction may not be completed or high-order misconvergence may occur. There was a drawback to that.

側に環状の磁性体を配置してなる偏向ヨークである。(d) Means for Solving the Problem The present inventor deflects an electron beam in a color picture tube in which an electron gun is arranged in-line, and uses a deflection yoke equipped with a saddle-shaped horizontal deflection coil and a toroidal-shaped vertical deflection coil. The deflection yoke is formed by disposing an annular magnetic body outside the horizontal deflection coil and on the rear end side of the vertical deflection coil.
(ホ)作 用
本発明は環状の磁性片を水平偏向コイルの外側かつ垂直
偏向コイルの後方(を子銃側)に装着することによって
、水平コイルの作る磁界は強められ従って、電子ビーム
はより大きく偏向される。(E) Function The present invention is characterized by attaching an annular magnetic piece to the outside of the horizontal deflection coil and behind the vertical deflection coil (on the child gun side), so that the magnetic field created by the horizontal coil is strengthened and the electron beam is greatly deflected.

通過することによって、水平のラスタ歪みはビンクツシ
ョン傾向へ変化する。The magnetic field created by the horizontal deflection coil is a binction magnetic field, and as the electron beam passes through an outer orbit, the vertical raster distortion changes with barrel tendency. The magnetic field created by the vertical deflection coil extends toward the electron gun, but since this is shielded by the annular magnetic body, the amount by which the electron beam is deflected is reduced. The magnetic field created by the vertical deflection coil is a barrel magnetic field, and as the electron beam passes through an inner orbit, the horizontal raster distortion changes to a binkction tendency.
