Abstract
An electron beam adjusting device used in a cathode-ray tube (CRT) of a television receiver, a display, etc., which is improved in the adjusting accuracy, reduced in the overall size and thickness, and also improved in the degree of freedom with which it is attached to the neck of a CRT. The electron beam adjusting device has pairs of two-, four- and six-pole ring magnets, which are attached around the neck of a cathode-ray tube used in a television receiver, a display, etc. The two-pole magnets, which are required to have a relatively high level of magnetic force, and the four- and six-pole ring magnets, which are not required to have a high level of magnetic force, are different in thickness from each other.
