Abstract

PURPOSE:To correct automatically distortion on the right and the left sides of an image and convergence even in a wide angle deflection tube, by equipping a pain of magnetic pieces having an extending part on the screen side of an image-receiving tube, and a pair of the second magnetic pieces between the vertical and the horizontal coils. CONSTITUTION:A capped rotary symmetrical conical core 71 to a deflecton neutral axis Z which run in the center of two axis; a pair of vertical coils 72 rolled at almost right angles to the circumference; and a pair of the first magnetic pieces 73 having extending parts 73, on the screen side on a shaft corresponding to the opposite angle of the image, provided near the opening of the core on the screen side, along its circumscribed surface, symmetrically to both sides are equipped. Further, a pair of horizontal coils 75 fitted in the vertical coils 72; and a pair of the second magnetic pieces 76 provided, symmetrically to up and down sides, to fit in the vertical and the horizontal coils 75 and 73 within the range from the bend-up 75, on the electron gun side of the coil 75 to almost the center of the opening of the core 71 on the electron gun side and the screen side are equipped.
