Abstract
A convergence correcting device is disclosed in which a first correcting element varies an inductance of horizontal correcting coils so as to correct a misconvergence in a saturable region of a flux generated according to the horizontal correcting coils of the saturable reactor, and the second correcting element corrects a misconvergence by increasing a flux density at the vertical side of the saturable reactor after focusing magnetic fields generated from vertical correcting coils and the magnet.
