The correction of misconvergence (yv) shown in the figure will be explained as an example. Auxiliary coil 21 wound around magnetic body 19.20 provided on the rear side of vertical deflection coil 15.16
．． 22 are connected in series to the vertical deflection coils 15, 16, respectively, and a sawtooth wave vertical deflection current flows through each auxiliary coil 21, 22 similarly to the vertical deflection coils 15, 1.6. As a sawtooth wave vertical deflection current flows through the auxiliary coils 21 and 22, a magnetic field B1 is generated in the magnetic body 19, as shown in FIG. 3, when looking below the horizontal center of the screen. A magnetic field B2 is generated in the body 2o. Here, the magnetic field B1+B2 is set in the same direction as the vertical deflection magnetic field (indicated by arrow V). Now, make the correction amount (sensitivity) of beam B larger (up) than the correction amount (sensitivity) of beam R.
By adjusting the variable resistor 24, the misconvergence (Yv) shown in FIG. 6 is corrected.
is adjusted so that the amount of current flowing through the auxiliary coil 22 wound around the magnetic body 20 is made larger than the amount of current flowing through the auxiliary coil 21 wound around the magnetic body 19.

も同時になされるものである。That is, the variable resistor 24 is adjusted so that the resistance value on the auxiliary coil 22 side is greater than the resistance value on the auxiliary coil 21 side. When the amount of current flowing through the auxiliary coil 22 becomes larger than the amount of current flowing through the auxiliary coil 21, the magnetic field B2 generated in the magnetic body 20 according to the amount of current becomes the magnetic field B generated in the magnetic body 19.
1, and as a result, the magnetic field (B
2) is greater than the magnetic field applied to the beam R,
The correction amount FB of the beam B becomes larger than the correction amount FR of the beam R based on the amount of magnetic field applied to the beam. (The sensitivity of beam B is greatly increased, and the sensitivity of beam R is slightly increased.) As a result, as shown in Figure 4 (A), beam B moves in the direction of the arrow (downward) at the bottom of the screen. Corrected. On the other hand, on the upper side of the screen, the correction coil 21
．． The vertical deflection current flowing through the magnetic bodies 19 and 22 is in the opposite direction to the lower side of the screen (due to the sawtooth current), and the direction of the magnetic field generated in the magnetic bodies 19 and 20 is also opposite. Therefore, the correction direction of the beams (B, R) on both sides is in the opposite direction (upward) to the lower side of the screen (Fig. 3), and as shown in Fig. 4 (A).
As shown in , at the top of the screen, beam B with a large amount of correction
is corrected in the direction of the arrow (up), and finally, as shown in Figure 4 (B)
As shown in FIG. 2, it is possible to obtain a screen in which the beams B and R on both sides coincide over the entire screen without misconvergence (Yv). At this time, the sensitivity of the beam G located at the center is simultaneously increased by the action of the magnetic fields B1+B2.

スコンバージェンスの補正がなされるものである。In one embodiment of the deflection yoke device of the present invention, an auxiliary coil wound around a magnetic material is connected in series with a vertical deflection coil, and a vertical deflection current is passed through the auxiliary coil to generate a magnetic field. As mentioned above, the auxiliary coil may be connected in parallel to the vertical deflection coil, and
The current flowing through the auxiliary coil is not limited to only the vertical deflection current, but a correction current synchronized with the vertical deflection current may also be passed, and in this case as well, the same effect as in the embodiment (beam movement adjustment) can be obtained. can. Further, in one embodiment of the present invention, a case has been described in which the magnetic material is provided on the rear side of the enlarged rear part of the coil bobbin, but the mounting position of the magnetic material is not limited to the embodiment. It may also be provided on the front surface of the enlarged rear portion of the coil bobbin. Furthermore, the shape of the magnetic piece is not limited to the rectangular shape of the embodiment as long as it is rod-shaped; for example, as shown in FIGS. It is also possible to use a concave T-shaped test, in which case the beams (B, R)
The application of the magnetic field (generated in the magnetic piece) to the magnetic field can be efficiently controlled. Furthermore, in one embodiment of the deflection yoke device of the present invention, misconvergence occurs when the amount of correction for beam B is smaller than the amount of correction for beam R (the sensitivity of beam B is insufficient compared to the sensitivity of the general beam). Although the correction operation has been described, it goes without saying that the present invention can be applied to correction of misconvergence in a state where the amount of correction for beam R is smaller than the amount of correction for beam B. Furthermore, in one embodiment of the present invention, the magnetic field generated in the magnetic material by the current flowing through the auxiliary coil is set in the same direction as the vertical deflection magnetic field, but the connection (winding direction) of the auxiliary coil is reversed to produce the vertical deflection. Even if the configuration is such that a magnetic field opposite to the magnetic field is generated in the magnetic material, there is no change in the operation, and the misconvergence is corrected.
ただし、この場合、センタービームの感度はダウンする
ものである。However, in this case, the sensitivity of the center beam is reduced.
〈発明の効果〉

Misconvergence on the screen can be corrected with an extremely simple configuration without any problems, and good screen characteristics can always be obtained. Also,
Compared to the conventional Y-shaped station that uses a magnetic body (core), the use of a rod-shaped magnetic body makes it smaller in size and requires less winding of the auxiliary coil, which is advantageous in terms of material and cost. Moreover, the work of winding the auxiliary coil around the magnetic material is extremely simplified, as it can simply be wound around a rod-shaped object.
This significantly improves work efficiency.
