摘要：PROBLEM TO BE SOLVED: To make a horizontal deflection coil used in common by eliminating vertical unbalance of horizontal deflection magnetic field components and making the horizontal deflection coil itself the same as the vertically symmetrical coil. SOLUTION: A turn ratio of a correction coil 6 for XV adjustment added to a horizontal deflection coil 5 is made variable. Namely, intensity balance of horizontal deflection magnetic field components on the upper side and the lower side is taken by changing the turn ratio between an upper side coil part 6a and a lower side coil part 6b of the correction coil 6. As a result, the generated unbalance of magnetic field is eliminated by making a cancel coil have a minimum constitution.
