ABSTRACT:
A mis-convergence correction device includes a first controlled coil unit, a second controlled coil unit, a controlling coil unit, and a coil holder. The first controlled coil unit includes first and second drum cores and a first controlled coil. Each of the first and second drum cores has circular flanges at its opposite ends respectively. The first controlled coil is provided on a portion of the first drum core between its flanges and also a portion of the second drum core between its flanges. The second controlled coil unit includes third and fourth drum cores and a second controlled coil. Each of the third and fourth drum cores has circular flanges at its opposite ends respectively. The second controlled coil is provided on a portion of the third drum core between its flanges and also a portion of the fourth drum core between its flanges. The controlling coil unit is located between the first and second controlled coil units. The coil holder accommodates the first and second controlled coil units and the controlling coil unit. The coil holder has first and second halves. The first half has a hold portion for each of the flanges of the first, second, third, and fourth drum cores. The hold portion has first and second inclined surfaces being non-parallel to each other. The first inclined surface contacts the related flange only at a first point as viewed in a cross-section of the related flange. The second inclined surface contacts the related flange only at a second point as viewed in the cross-section of the related flange. The first and second points are separate from each other.
