いた。Conventional configuration and its problems In general, as a form of deflection yoke, a vertical deflection coil is wound around the outer circumference of the core in a toroidal shape.
Also known is a structure in which a horizontal deflection coil is wound in advance into a saddle shape and arranged on the inner surface of a core with an insulating frame interposed therebetween. In this case, it is easy to match the magnetic field center of the horizontal deflection coil with the dimensional center of the insulating frame, but it is not easy to match the magnetic field center of the vertical deflection coil with the dimensional center of the insulating frame. Instead, an axis cross in which the red axis 2 and the blue axis 3 were misaligned appeared on the screen 1 as shown in FIG.

装方式である。 Figure 2 is a cross-sectional view of the upper half of the toroidally wound coil, in which three layers of winding 5, 2nd layer 6, and 3rd layer winding 7 are wound on core 4. It is something. If you draw a circuit diagram of this, it will look like Figure 3. Each layer has a different winding width, and the wide winding width has a barrel distribution, and the narrow winding width has a pink tension distribution. The conventional winding method creates the required magnetic field distribution.

The center of the vertical deflection coil and the center of the magnetic field can be easily aligned.

記、軸クロスをなくすことができるのである。Structure of the Invention In the present invention, a variable resistor is connected in parallel with a coil in a specific layer, and the current flowing in the specific layer is changed by the variable resistor, thereby changing the overall magnetic field distribution. Therefore, even if the magnetic field center of the wound coil does not coincide with the dimensional center of the insulating frame or the center of the electron beam, the magnetic field center of the coil can be moved by adjusting this variable resistance. , as mentioned above, it is possible to eliminate the axis cross.
実施例の説明
第４図は本発明の一実施例の回路図であり、従
来例のものと同一部材は同一の番号を示す。DESCRIPTION OF THE EMBODIMENT FIG. 4 is a circuit diagram of an embodiment of the present invention, in which the same members as those of the conventional example are denoted by the same numbers.
つまりコア４上に第１層目巻線５、第２層目巻
線６、第３層目巻線７が巻かれ、この例では第３
層目巻線７と並列に可変抵抗器８が接続されてい
る。 That is, the first layer winding 5, the second layer winding 6, and the third layer winding 7 are wound on the core 4, and in this example, the third layer winding 7 is wound on the core 4.
A variable resistor 8 is connected in parallel with the layered winding 7.

線７に流れる電流が少くなつてピンクツシヨン磁
界が弱まり、赤ビーム２と青ビームが近づく。 Here, assuming that the barrel magnetic field is strong as a whole, the resistance value of the variable resistor 8 is adjusted in the direction of increasing it. Then, blue beam 3 and red beam 2 approach. Also, if the pink tension magnetic field is strong, the variable resistor 8
The current flowing through the third layer winding 7, which adjusts the resistance value of the red beam 2 to be small, decreases, the pink tension magnetic field weakens, and the red beam 2 and blue beam become closer together.
さらに、場合によつては他の層に可変抵抗器を
接続することも考えられる。 Furthermore, depending on the case, it may be possible to connect a variable resistor to another layer.
