And the winding direction of the main winding coil and the auxiliary winding coil, and the winding of the transition portion from the first region to the second region. By configuring the winding direction of the wire to be the same direction, it is possible to obtain a magnetic field distribution that cannot be obtained by ordinary coil winding. It is configured such that the windings can be formed in the same direction.

図中矢印ｉで示す方向及びその逆方向に流れる。[Related Art] A deflection yoke in a cathode ray tube (CRT) includes a pair of vertical deflection coils and a pair of horizontal deflection coils. For example, the horizontal deflection coil is wound around a saddle-shaped bobbin, so that the coil is wound in a saddle shape as shown in FIG. Is determined by the distribution of the current flowing in the total cross section of. Note that the Z axis coincides with the beam optical axis. Further, when viewed in a plane with the X-axis and the Y-axis as references, the winding method of the coil is as shown in FIG.
It flows in the direction indicated by arrow i in the figure and in the opposite direction.
コイル断面は、Ｘ軸,Y軸を基準とすると第６図に示す
ように表わすことができる。The coil cross section can be represented as shown in FIG. 6 based on the X axis and the Y axis.
ここで、第６図における第１象限（コイルの右側断

が流れているものとし、第２象限（コイルの左側断面）
では逆に紙面裏から紙面上に向かう方向に電流が流れて
いる場合を想定する。Here, in the first quadrant (the right cross section of the coil) in FIG. 6, it is assumed that a current flows from the top of the paper to the direction passing through the paper, and the second quadrant (the left cross section of the coil).
On the contrary, it is assumed that a current is flowing in a direction from the back of the paper to the top of the paper.
このとき、第６図のコイル右側断面における電流分布
についてみてみると、縦軸に電流強度Ｉ、横軸にＸ軸に
対する角度θをとった第７図に示されるとおりとなる。
なお、左側断面の電流分布は第７図と対称に表わされる
（極性は逆）。At this time, the current distribution in the right-side cross section of the coil in FIG. 6 is as shown in FIG. 7, in which the vertical axis represents the current intensity I and the horizontal axis represents the angle θ with respect to the X axis.
Note that the current distribution on the left side section is represented symmetrically with FIG. 7 (the polarity is reversed).

おいてθａ〜θｂの部分の捲線数を少なくすれば、第８
図のような電流分布を得ることができ、従って、所定の
コンバーゼンス特性を備えた磁界を得ることができる。By the way, it is generally known that the convergence characteristics can be improved by manipulating the magnetic field distribution of the deflection yoke, and it is necessary to reduce the amount of current in a predetermined portion by changing the shape of the coil or partially adjusting the number of windings. And so on. For example, if reducing the winding number of the parts of the theta a through? B in the coil current distribution as shown in FIG. 7, 8
A current distribution as shown in the figure can be obtained, and thus a magnetic field having a predetermined convergence characteristic can be obtained.
しかしながらこのような方法により所定の磁界分布を
得る方法では、所定部分の捲線をゼロとした状態が限界
である。すなわち、θａ〜θｂ間を捲線ゼロとした場合
の第９図の電流分布状態である。However, in a method of obtaining a predetermined magnetic field distribution by such a method, a state where a winding of a predetermined portion is set to zero is a limit. That is, this is the current distribution state in FIG. 9 when the winding between θ a and θ b is zero.
これ以上に磁界分布の設定の自由度を広げたい場合
は、例えば第10図のようにコイルを途中で折り返して捲
回することにより、例えばθａ〜θｂ間だけ逆方向の電
流を得ることができ、このようにすれば例えば第11図の
ような電流（磁界）分布状態を設定することも理論的に
は可能となる。If it is desired to further increase the degree of freedom of setting the magnetic field distribution, for example, a coil is folded back and wound in the middle as shown in FIG. 10 to obtain, for example, a current in the reverse direction only between θ a and θ b. In this way, it is theoretically possible to set a current (magnetic field) distribution state as shown in FIG. 11, for example.
［発明が解決しようとする問題点］ しかしながら、上記第10図のようにある部分で折り返
してコイルを捲回することは製造上困難であり、実際的
ではない。[Problems to be Solved by the Invention] However, as shown in FIG. 10, it is difficult to manufacture a coil by winding it back at a certain portion, which is not practical.
なぜなら、通常、コイルボビンにコイルを捲回してい
く捲線機は、常に一定方向に捲線動作を行なうように設
計されており、コイル捲回中に折り返し動作を行なわせ
るためには新たな捲線機を製作しなければならず、必要
以上の費用及び時間的損失が生ずる。Because, usually, a winding machine that winds a coil on a coil bobbin is designed to always perform a winding operation in a fixed direction. Must be done, resulting in unnecessary costs and time losses.
このため、従来は実際にθａ〜θｂ間で磁界分布状態
を変化させようとした場合、上記第９図の状態がその限
界であり、コンバーゼンス補正等のための磁界設定の自
由度が小さいという問題があった。Therefore, conventionally, when actually trying to change the magnetic field distribution state between θ a and θ b , the state shown in FIG. 9 is the limit, and the degree of freedom in setting the magnetic field for convergence correction is small. There was a problem.

Each of the coil portions for generating the deflection magnetic field of FIG.
When the first quadrant region and the second quadrant region in the figures and the like are the first and second regions, respectively, in each of the first and second regions, one round of the coil is completed only within that region. It is to provide a deflection coil in which a coil is wound so that a coil portion (auxiliary winding portion) is formed.

しかも、この場合にコイル捲回方向を逆にして折り返す
必要はない。[Operation] For example, as shown in FIG. 1 as points A to B and points C to D, if an auxiliary winding portion in which one turn of the coil is completed only in one area is formed, the first area is formed. it can be from the conventional current direction i F opposite current direction i R when the second region one round toward is wound, obtained in each region.
Moreover, in this case, there is no need to reverse the coil winding direction and turn it back.

Reference numeral 28 denotes a locking piece formed symmetrically at the rear of the bobbin. Reference numeral 30 denotes a coil wound in a saddle shape by using the locking pieces 2 to 18 and 20 to 28 of the coil bobbin 1 as guides.

For example, as shown in FIG. 3, an auxiliary winding portion which can complete the one turn of the coil and adjust the magnetic field distribution is formed only in one of the regions, as shown in FIG. It is wound to be.

When the point is reached, one round in area 1 has been completed. Similarly, in the area 2, when the coil is wound from the point C to the point D via the locking piece 11, one round is completed only in the area 2. From point D onward, all windings are wound from region 2 to region 1 to complete one round.

で容易に製造することができる。With this winding, in each region, respectively to the main deflection current direction I F, the current direction I R opposite will occur. Therefore, as the current intensity distribution, for example, the one shown in FIG. 11 is obtained, that is, the degree of freedom in setting the magnetic field distribution is expanded. In addition, there is no need to reverse the winding direction and fold the portion including the portion crossing the intermediate portion between the first region and the second region.
Since the coil winding can always be completed by the winding operation in a fixed direction, the horizontal deflection coil of the present embodiment can be easily manufactured by a conventional winding machine.

However, the portion to be made in the reverse direction and the number of windings thereof are set based on the magnetic field distribution required to be generated. In any case, it suffices if the circuit is designed so that one round is completed only within the area.
また、本発明は垂直偏向コイルとしても実施できるこ
