There is a problem that the order of 11 is changed and it is not possible to wind according to the design instruction, and the deviation state of the winding 11 of each deflection coil to be mass-produced also varies for each product, and the deflection magnetic field is There was a problem that it could not be controlled accurately. Further, since the mass-produced products vary, there is a problem that the yield is reduced, and there is a problem that the conventional winding method cannot cope with the cost. Even with this conventional method, if the width of the coil winding groove is made narrower, the deviation or deviation of the winding 11 can be reduced to approach the design instruction, but in this case, the ratio L / R of the inductance L and the resistance R can be obtained.

する。When the saddle-shaped bobbin 2 is wound with the multi-core parallel conductors 15 by the flyer type winding machine, the multi-core parallel conductors 15 are twisted at the crossover portions on the head side and the tail side of the bobbin 2. Since there is a problem that the coil is wound around or is dislocated from the coil winding groove 5, the applicants proposed a dedicated winding machine for the purpose of solving this problem. The process of winding the multi-core parallel conductor 15 around the bobbin 2 using this dedicated winding machine will be described with reference to FIG. 3. First, the bobbin 2 moves in the direction of the arrow, and at the same time the multi-core parallel conductor 15 is moved. The multi-core parallel conductor 15 is wound in the groove of the right inner peripheral wall surface 45 of the bobbin 2 while moving in the X-axis direction so that the nozzle 30 for feeding out the bobbin 2 faces the inner peripheral surface of the bobbin 2 while maintaining a predetermined interval. Next, the nozzle 30 faces the head-side crossover wire portion, and the nozzle 30 is rotated and moved to the coil winding groove 5 of the crossover wire portion, and the multicore parallel conductor 15 is inserted into the coil winding groove 5 of the head-side crossover wire portion. When winding, the multi-core parallel conductor 15 is twisted at the crossover portion and wound while being controlled so as not to be disengaged from the coil winding groove 5, so that a long time is required for these control times. And after winding the head side crossover part,
The multi-core parallel conductor 15 is wound in the groove of the left inner peripheral wall surface 46, and then the tail side connecting wire portion is wound for a long time like the head side connecting wire portion. By repeating this operation, the deflection coils are wound in layers.

問題があった。As described above, winding a multi-core parallel conductive wire 15 around the saddle-shaped bobbin 2 to manufacture a deflection coil requires complicated winding work, and particularly, the crossover wire portions on the head side and the neck side. Since the winding operation is complicated to control the winding operation and it takes a long time, the work efficiency is poor and the productivity of the deflection coil is low.
【００１２】また、この専用巻線機は制御が極めて複雑
なため、どうしても高価となり、この価格が偏向コイル

するという問題があった。Further, since the control of this special winding machine is extremely complicated, it is inevitably expensive, and this price directly repels the manufacturing cost of the deflection coil, so that the manufacturing cost is increased.

がるという問題があった。Further, in order to reduce the winding time, a multiple winding system in which several winding machines are used at the same time is used. In this case, many windings used at the same time are used. Since the total device cost of the machine directly rebounds to the manufacturing cost of the deflection coil, there is a problem that the manufacturing cost is also greatly increased.
