PURPOSE:To compensate coma aberration with a sole body of deflection yoke by providing a ?-shaped core at the rear side of deflection coil or core and by winding a part of coil including both cores. CONSTITUTION:A ?-shaped subcore 15 is loaded to the area behind the main core 4 for troidal vertical deflection coil and the vertical deflection coil is wound to such core. The vertical deflection coil has the shape that a part of the vertical deflection coil is wound simultaneously to the ?-shaped subcore. Thereby, coma aberration and misconvergence can be compensated simultaneously. |
