る。(Prior Art) A rotary transformer is used to transmit signals from a fixed VTR circuit to a rotating magnetic head, and also to transmit signals read from a magnetic tape by the rotating magnetic head to a fixed VTR circuit. The rotating core and stationary core are inserted into the VTR cylinder with a small gap,
The rotating core rotates at several hundred revolutions or more per minute.

接着を行つていた。 A conventional example will be explained using a cross-sectional view of a flat plate type rotary transformer. Conventionally, when bonding a winding wire to a ferrite core, solvent-emitting adhesives,
In particular, rubber adhesives were used. Adhesive 4 is applied to the groove surface of the ferrite core 1 shown in FIG. 2a, and the state shown in FIG.
I was doing the gluing.
（発明が解決しようとする問題点）
従来の接着作業の場合、溶剤発散型接着剤で
は、溶剤発散に関与する温度、時間の管理が複雑
であり、工程の簡素化及び、接着強度の安定化を
得ることが困難であつた。(Problems to be Solved by the Invention) In the case of conventional bonding work, with solvent-emitting adhesives, the management of temperature and time involved in solvent-emitting is complicated, and it is necessary to simplify the process and stabilize the adhesive strength. It was difficult to obtain

た。 Furthermore, solvent-emitting synthetic rubber adhesives have a phenomenon of adhesive stringing, and in rotary transformers that rotate at high speeds, the adhesive in the form of threads remaining on the groove surface of the rotary transformer can cause wind noise. This was causing the occurrence of defects and disrupting dimensional accuracy.

102345号にて出願し、工数低減、巻線接着強度の
向上等良好な結果を得ている。 In order to improve the above-mentioned drawbacks, the present inventor proposed a rotary transformer using an ultraviolet curable modified acrylic adhesive for the ferrite core and windings in a patent application filed in 1983.
No. 102345 was filed, and good results have been obtained such as reduction in man-hours and improvement in winding bond strength.
しかし、ロータリートランスの多チヤンネル化
にともない、多チヤンネルロータリートランスの
巻線接着においては、以下の問題点が生じた。 However, as rotary transformers have become multichannel, the following problems have arisen in bonding the windings of multichannel rotary transformers.
第３図に示す様に、巻線を加圧した状態にて、
紫外線を照射し、接着剤を硬化させる必要があ
る。 As shown in Figure 3, when the winding is pressurized,
It is necessary to irradiate the adhesive with ultraviolet light to harden it.
しかし、多チヤンネルロータリートランスにお

が約0.2mmあり、各巻線を均一に加圧することが
困難であつた。さらに、各巻線の線径が異なる場
合も均一に加圧接着することは困難である。 However, in a multi-channel rotary transformer, the groove depths between the innermost groove and the outermost groove vary by about 0.2 mm, making it difficult to uniformly pressurize each winding. Furthermore, even when the wire diameters of the windings are different, it is difficult to uniformly bond them under pressure.
上記の欠点の為、多チヤンネルロータリートラ

素化という利点が失なわれていた。 Due to the above-mentioned drawbacks, in multi-channel rotary transformers, the process of applying adhesive to each groove, inserting the coil and applying pressure, and then irradiating the adhesive with ultraviolet light (curing the adhesive) had to be repeated for several grooves. Therefore, the cost increases due to the complexity of the process, and the advantage of simplifying the process due to the use of the ultraviolet curable modified acrylic adhesive is lost.
