偏向磁界を与える偏向ヨーク装置に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a deflection yoke device that is attached to a color picture tube and applies a deflection magnetic field to three electron beams emitted from an electron gun of the color picture tube.

み立てられている。Conventional Structure and Problems Generally, as shown in Fig. 1, a deflection yoke consists of a pair of horizontal deflection coils 1a and 1b that are wound in a vertically symmetrical distribution around the yoke horizontal axis X.
and a pair of vertical deflection coils 2 wound in a symmetrical distribution around the yoke vertical axis Y.
a, 2b, both deflection coils 1a, 1b, 2
a and 2b are integrally assembled using the insulating cylinder 3 as a support frame.

６，７が相互に一致しなくなる。 Such a deflection yoke must be attached to the color picture tube so that its central axis Z is coaxial with the central axis of the electron gun, but in reality it tends to be eccentric.
If this happens, a misconvergence as illustrated in FIG. 2 will occur, and the blue, green, and red rasters 5 and
6 and 7 no longer match each other.

ミスコンバーゼンスが残る。 If the eccentricity described above occurs, it can be corrected to some extent by slightly tilting the deflection yoke attached to the color picture tube using the tilt adjustment mechanism, but a complete correction effect cannot be expected, and the error shown in Fig. 3 can be avoided. Convergence remains.
