あった。As the azimuth adjusting screw 6, a commercially available screw is used. As shown in FIG. 5, the commercially available screw has a bottom surface of the screw head 6a inclined at an angle α and a length 6b of the bottom surface.
Even if occurs, this inclination is within the allowable range of JIS standard, so if you use this commercially available screw to adjust the azimuth, the height is adjusted by the rotation stop position of the screw head at the angle of the bottom surface, As shown in FIG. 6, the tape sliding contact surface between the pedestal 8 and the head 1 goes down or goes up as shown by the arrow, and the azimuth cannot be adjusted with high precision. There was a drawback that the output changed.
本考案は前記欠点に鑑み、市販のネジを使用しても精度
の高いアジマス調整が出来る磁気ヘッドの台座を提案す
ることである。In view of the above-mentioned drawbacks, the present invention proposes a pedestal of a magnetic head capable of highly accurate azimuth adjustment even when a commercially available screw is used.

よりも高い凸部を形成したことにある。The present invention is directed to a line connecting the center of a screw hole for attaching a head to a substrate formed on a lower pedestal and the center of an azimuth adjusting screw hole or a U hole, and also for the azimuth adjusting screw hole or a U hole. This is because a convex portion higher than the inclination dimension of the screw head of the azimuth adjusting screw was formed in the vicinity.
以下、図示の一実施例で本考案を説明する。第１図、第

ラー５を挟んで取付け用ネジ３が基板４に螺合されて台
座２の一側2aが固定されている。Hereinafter, the present invention will be described with reference to an illustrated embodiment. In FIG. 1 and FIG. 2, the magnetic head pedestal has a mounting screw 3 inserted into a mounting screw hole 2b formed in one side 2a of a slender plate-shaped pedestal 2 to which the head 1 is fixed. A mounting screw 3 is screwed to a substrate 4 with a base collar 5 placed on the top of the base collar 5 interposed therebetween, and one side 2a of the base 2 is fixed.
台座２の他側2cにはアジマス調整ネジ用Ｕ孔2dが穿設さ
れてアジマス調整用ネジ６が挿入され、基板４との間に
コイルバネ７を挟んでアジマス調整用ネジ６が基板４に
螺合されている。On the other side 2c of the pedestal 2, a U hole 2d for azimuth adjusting screw is bored and an azimuth adjusting screw 6 is inserted. A coil spring 7 is sandwiched between the azimuth adjusting screw 6 and the substrate 4, and the azimuth adjusting screw 6 is screwed onto the substrate 4. Have been combined.
台座２のアジマス調整ネジ用Ｕ孔2dの側部近傍で、取付
けネジ用孔2bの中心とアジマス調整ネジ用Ｕ孔2dの中心

部2eが突出形成されている。Near the side of the azimuth adjusting screw U hole 2d of the pedestal 2, on the line connecting the center of the mounting screw hole 2b and the center of the azimuth adjusting screw U hole 2d, and the screw head 6a of the azimuth adjusting screw 6.
Within the range, a convex portion 2e other than the inclination dimension 6c of the screw head 6a is formed on the lower side so as to project.
前記のように磁気ヘッドの台座が構成されてアジマス調
整用ネジ６がコイルバネ７の付勢力に抗して回動される
と、ネジ頭6aの底面が凸部2eに当たり、台座２の他側2c
が下降されてアジマス調整がなされる。When the pedestal of the magnetic head is constructed as described above and the azimuth adjusting screw 6 is rotated against the urging force of the coil spring 7, the bottom surface of the screw head 6a hits the convex portion 2e and the other side 2c of the pedestal 2 is rotated.
Is lowered and azimuth adjustment is performed.
この時ネジ頭6aの外面は凸部2e以外の台座２の他側2cに
当たらないから、台座２は第３図のように上下にのみ移
動されて第６図のように傾くことがないので精度の高い
アジマス調整が可能になり、テープ摺接面が上下しない
からテープの走行や出力が安定する。At this time, since the outer surface of the screw head 6a does not contact the other side 2c of the base 2 other than the convex portion 2e, the base 2 is moved only up and down as shown in FIG. 3 and is not tilted as shown in FIG. Highly accurate azimuth adjustment is possible and the tape sliding contact surface does not move up and down, so tape running and output are stable.
前記説明ではアジマス調整用ネジ６が挿入される孔をア
ジマス調整ネジ用Ｕ孔2dとしたが、アジマス調整ネジ用
孔としてもよい。In the above description, the hole into which the azimuth adjusting screw 6 is inserted is the U hole 2d for azimuth adjusting screw, but it may be a hole for azimuth adjusting screw.
更に前記説明では凸部2eが台座２から突出形成された
が、他の形状の凸部を台座２に植設固定してもよい。Further, in the above description, the convex portion 2e is formed so as to project from the pedestal 2, but a convex portion having another shape may be fixed to the pedestal 2 by implantation.
本考案は前述のように構成されたから、ネジ頭の底面は
凸部以外の台座に当たらないので、台座は上下にのみ移
動されて精度の高いアジマス調整が可能になり、テープ
の走行や出力が安定する等実用上優れた効果を奏する磁
気ヘッドの台座を提供することが出来る。Since the present invention is configured as described above, since the bottom surface of the screw head does not hit the pedestal other than the convex portion, the pedestal can be moved only up and down to enable highly accurate azimuth adjustment, and tape running and output can be performed. It is possible to provide a pedestal of a magnetic head that exhibits excellent practical effects such as stability.
