Abstract

PURPOSE: To reduce the distortion in the picture reproduced on the fluorescent screen, by adding magnetic substance to the deflecting yoke having the semi-troidal type deflection coil.
CONSTITUTION: At the fluorescent screen side of the deflection coil 12 having the semi-troidal type deflection coil, the magnetic substance 13 consisting of four rectangular shape chips are provided at the symmetrical position to the horizontal axis X-X' and the vertical Y-Y'. That is, the magnetic substance 13 is taken so that the lengthwise direction is about the corner of the effective deflection plane 17 to the rectangular shaped fluorescent screen of electron beam near the part mounted on the magnetic substance 13 and it is provided to clip the pole 15, resulting in obtaining the pin cushion type of the magnetic field distribution of vertical deflection leakage as shown in broken lines 16. Further, when the winding distribution is changed for the vertical deflection coil, it forms barrel type greater at the electron gun to simultaneously perform the reduction in the picture distortion left and right and the convergence correction.
