る。Composition of the Invention In order to achieve this object, the present invention requires the use of a vertical coil with little variation in size and shape, but when the coil is formed into a semicircular shape, the end face is also formed to have a constant size. A coil with good dimensions has been obtained, and two vertical coil gap widths are placed at right angles to the horizontal coil fixing protrusion provided on the outer periphery of the bobbin and located at the middle window of the horizontal coil. The structure is such that two convex portions corresponding to the same width are provided on the outer periphery of the bobbin.

となるとともに装着作業性も良好となる。 With this configuration, both the horizontal coil and the vertical coil are installed so that the gap between the coils is on the convex part provided on the outer circumference of the bobbin, so that the horizontal coil and the vertical coil are arranged at right angles, and the two Since the vertical coil is fixedly mounted without shifting, there is no need to adjust the perpendicularity between the horizontal coil and the vertical coil, and the mounting workability is also improved.
実施例の説明
以下、本発明の一実施例を第３図、第４図を用
いて説明する。なお、第３図、第４図中、第１図
と同一部品については同一番号を付している。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. In FIGS. 3 and 4, the same parts as in FIG. 1 are given the same numbers.
図において、ボビン３の外周上で水平コイル１

る。 In the figure, horizontal coil 1 is placed on the outer circumference of bobbin 3.
Two protrusions 3b are formed at right angles to the positioning protrusion 3a of the horizontal coil 1 at the middle window 1a, and have a width corresponding to the width of the two gaps of the vertical coil 2.
次に、上記構成によるボビン３に垂直コイル２
を装着する場合について説明すると、垂直コイル
２の円周方向端面を垂直コイル位置決め凸部３ｂ

装着することで垂直コイル２は位置決めされて固
定装着される。また、光軸方向位置決めもボビン
３の鍔３ｃと同様な鍔を偏向コイルの反対側に設
けることで偏向コイルは全方向の位置固定装着が
できる。 Next, the vertical coil 2 is attached to the bobbin 3 with the above configuration.
To explain the case where the vertical coil 2 is mounted on the circumferential end surface of the vertical coil positioning convex portion 3b,
The vertical coil 2 is positioned and fixedly mounted by making it come into contact with the bobbin 3 and making it come into contact with the collar 3c of the bobbin 3. Further, for positioning in the optical axis direction, by providing a flange similar to the flange 3c of the bobbin 3 on the opposite side of the deflection coil, the deflection coil can be mounted in a fixed position in all directions.
このように、偏向コイルには水平コイル１、垂
直コイル２とも片寄りなく位置固定装着されるこ
とで水平コイル１と垂直コイル２との直角度も確
保され、装着作業も良好となる。 In this way, since both the horizontal coil 1 and the vertical coil 2 are mounted in a fixed position on the deflection coil without any deviation, the perpendicularity between the horizontal coil 1 and the vertical coil 2 is also ensured, and the mounting operation becomes easy.
