徴とするコンバーゼンス補正装置。[Claims for Utility Model Registration] Convergence correction consisting of two sets of correction coils with different magnetic pole spacing, arranged at the rear end of a self-convergence type deflection yoke in which the horizontal deflection magnetic field is pink-tensioned and the vertical deflection magnetic field is barrel-shaped. In the device, the two sets of correction coils include a pair of first correction coils with a narrow magnetic pole spacing and a pair of second correction coils with a wide magnetic pole spacing.
When a sawtooth wave current synchronized with the vertical deflection current is passed through the first correction coil and the second correction coil, the magnetic property of the first correction coil changes depending on the vertical deflection. A convergence correction device characterized by being saturated in the upper and lower parts from the middle.
