摘要： PROBLEM TO BE SOLVED: To provide a low-cost deflection yoke which has a small number of parts and assembling man-hours, while having deflection correction characteristics equal to or better than that of a conventional one, in one provided with a saturable reactor.
SOLUTION: The saturable reactor is provided with saturable cores 1a, 1b, impedance control coils 2a, 2b connected with a horizontal deflection coil and wound around the saturated cores 1a, 1b, a magnet 5 of giving a magnetic bias to the saturated cores 1a, 1b, a magnetic core 3 forming a closed magnetic circuit 6, and a saturation control coil 4 through which a vertical deflection current flows and wound around the magnetic core 3. The direction of a vertical deflection saturation controlling magnetic field generated by the saturation controlling coil 4 is made in the same direction at the time of both the top side deflection of a screen and the bottom side deflection.
