Abstract

PURPOSE:To simply adjust beam landing error by providing a purity adjusting magnet between each neck side end of vertical and horizontal deflection coils in a deflector. CONSTITUTION:A pair of ring-shaped or equivalent purity magnets 23 and 24 with projections 231 and 241 are provided between the bent-ups 181 and 191 of the side end for the neck 14 of horizontal deflection coils 18 and 19 and the neck side ends 211 and 221 of vertical deflection coils 21 and 22. A pair of these purity magnets are freely rotatably arranged between the projection 20b at the body 20a of a separator 20 and the projection 20d at the pocket 20c in which the bent-ups 181 and 191 for the neck side end of the horizontal deflection coils 18 and 19. This can simply adjust beam landing error even for a picture tube that uses a dynamic convergence free system.
