型カラー受像管用偏向装置。[Claims for Utility Model Registration] A deflection yoke having a pair of horizontal and vertical deflection coils each generating a magnetic field that deflects three electron beams emitted from an electron gun and arranged in a row on the same horizontal plane in the horizontal and vertical directions; , a pair of U-shaped cores are arranged in the three electron beam passing region on the electron gun side of the deflection yoke, sandwiching the alignment axis of the three electron beams, and the vertical deflection coil is wound around the pair of cores. A pair of sub-coils that generate a dynamic magnetic field that corrects comatic aberration in the vertical axis direction of the screen drawn by the three electron beams by applying a current to the sub-coils; The above three coils generate a static quadrupole magnetic field in the electron beam passing area, and the three above electron beam passing areas are sandwiched between the three electron beam passing areas on the electron gun side of the deflection yoke.
A static coil that is wound around a pair of rod-shaped cores arranged on the electron beam alignment axis and generates a static two-pole magnetic field by cooperating with a coil that generates the four-pole magnetic field when DC current is applied. 1. An in-line deflection device for a color picture tube, comprising a convergence correction means.
