PURPOSE:To achieve automation through simple robot by adjusting the relative positional relation between a vertical deflection coil and a horizontal deflection coil then securing the core and the separator through adhesive thereby adjusting the asymmetry of deflection coil thoroughly. CONSTITUTION:A horizontal deflection coil 5 is secured to the inside of a plastic separator 4 while a vertical deflection coil 7 wound around the core 6 is fitted over the separator 4. A gap 8 is provided for the vertical deflection coil 7 wound around the separator 4 and the core 6 to have predetermined initial movable ranges in the directions X, Y and theta while the separator 4 and the vertical deflection coil 7 or the core 6 are secured through adhesive 9. Consequently, not the local adjusting of magnetic field distribution but the radical adjusting of the asymmetry of deflection coil field can be achieved resulting in automation through simple robot. |
