特徴とする偏向ヨーク装置。[Claims for Utility Model Registration] Four deflection devices near the bend on the side of the horizontal deflection coil neck of a deflection device having a saddle-shaped horizontal deflection coil and a toroidal vertical deflection coil for the purpose of improving the electron beam spot and focus. In a deflection yoke device equipped with a magnet, a pair of correction pieces are arranged on the left and right sides of a ring-shaped non-magnetic plate coaxial with the tube on the x-axis, which coincides with the horizontal direction and passes through the center of the vertical direction. A deflection yoke device characterized in that it is capable of convergence correction using the magnetic field of a magnet.
