摘要： A landing correction coil is provided at the rear of a horizontal deflection coil of a deflection yoke or at a position where it is closely coupled with the horizontal deflection coil. The landing correction coil is fixed so as to generate a magnetic field perpendicular to the axis of a CRT. Moreover, the landing correction coil is connected so that a current flowing in a horizontal deflection coil may flow in the landing correction coil. Furthermore, the landing correction coil is connected to an adjustment coil for adjusting the current flowing therein. A varying means is provided in the adjustment coil and the polarity and amplitude of the current flowing in the landing correction coil is adjusted by the varying means. This causes the magnetic field distribution for scanning an electron beam of a CRT to be changed and enables a landing characteristic to be adjusted electrically.
