ことができる。In this embodiment, as shown in FIG. 4 and FIG. 6A, a member disposed between the fluorescent screen side 7 end and the electron gun side 8 end of the coil frame 2 so as to overlap the magnetic core 5. Tab 2c
It has. The conducting wire of the horizontal deflection coil 3 is wound from the 8 end on the electron gun side to the 7 end on the phosphor screen side, and a part thereof is formed in the groove of the guide portion 2a provided in the coil frame 2 on the 7 end on the phosphor screen side. After being formed along, it is folded back from the guide portion 2a, and follows the path different from the going, the above-mentioned locking piece 2c
After passing through, the groove again passes through the guide portion 2a at the end on the fluorescent screen side, and returns to the end on the electron gun side.
As a result, as shown in FIG. 6 (b), the deflection magnetic field generated by the horizontal deflection coil 3 of this embodiment is changed to a horizontal deflection coil 3f having a constant winding direction and a fluorescent screen side 8 formed by the horizontal deflection coil 3f.
This shows the same magnetic field distribution as when a new auxiliary coil 9 for suppressing the magnetic field is provided. That is, the coil magnetic field in the range from the fluorescent screen side 8 end to the locking piece 2c is generated by the magnetic field generated by the conducting wire from the electron gun side 7 end to the fluorescent screen side 8 end and from the fluorescent screen side 8 end to the locking piece 2c. The strength of the magnetic field depends on the length of the groove of the guide portion 2a provided at the end of the phosphor screen 8 and the distance from the end of the phosphor screen 8 to the locking piece 2c. It can be controlled freely by changing the distance. Therefore, the deflection magnetic field can be changed in the tube axis direction.

おける領域である。Further, as shown in FIG. 5, the crossover portion 3d of the horizontal deflection coil 3 wound via the above-described locking piece 2c is moved in a direction in which the electron beam is deflected by the horizontal deflection coil 3. They are arranged in a direction substantially perpendicular to the axis, that is, on a vertical axis representing a vertical axis with respect to a horizontal axis representing a horizontal axis in FIG. For this reason, the range of the effect of the magnetic field formed by the horizontal deflection coil 3 wound via the above-described locking piece 2c is the central area on the fluorescent screen side 7, particularly the area in the vertical direction. .

に比較して、格段に改善させることが出来る。As a result, when the red, green, and blue electron beams emitted from the electron gun reach the phosphor screen through the magnetic field formed by the deflection coil, the electron beams are deflected and shaken. Misconvergence (color misregistration) caused by amplitude deviation and image distortion especially in the vertical direction among images formed on the phosphor screen can be reduced by using a deflection coil wound without using the locking piece 2c or by using an electron gun. Compared to the case where the magnetic field is controlled, it is possible to remarkably improve.

Instead of bending the transition portion 3d on the fluorescent screen side 7 of the horizontal deflection coil 3 to the electron gun side 7 via 2c, it is curved on the fluorescent screen side 7 of the transition portion 3e of the horizontal deflection coil 3 on the electron gun side 8. It may be shaped.

There is no problem such as an increase in the cross-sectional area or complicated connection of the coil, and a setting with a high degree of freedom by partially changing the deflection magnetic field can be performed, which is extremely effective in improving image distortion and misconvergence.
