ABSTRACT:
Subcoils are provided on the core portion that serves as a deflection yoke, and a current for correcting convergence is supplied to the subcoils to correct convergence. Further, means is provided to suppress harmful current that is produced by mutual induction between the subcoils and the deflection coils, and whereby the deflection of electron beam and the correction of convergence are effected independently of each other.
