気テープ装置の磁気ヘッドをアジマス調整する機構に関
する。The present invention relates to a magnetic head azimuth adjusting mechanism, and more particularly to a mechanism for adjusting the azimuth of a magnetic head of a magnetic tape device.

り付け面側の角度調整が可能となる。A conventional magnetic head azimuth adjusting mechanism holds a magnetic head 1 as shown in FIG. 3, and a head 2 at one end and a base 2 at one end of which a head mounting surface side and a base mounting surface side are connected by a rib. Side of the differential screw 4 and the differential screw 4 and the differential screw retainer 8 engaged with the side of the head and the other end of the differential screw 4 attached to the base mounting side of the base and the screw having a pitch different from the head mounting surface side. It is constituted by a press nut 9 which engages with a screw portion provided on the portion 8 and is installed between the head mounting surface side and the base mounting surface side of the base 2, and the base 2 is formed by the difference in the pitch of the differential screw 4. It is possible to adjust the angle of the head mounting surface side with respect to the base mounting surface side.

差動ネジを破損する恐れがあり、また、組立て作業時間
が長くかかるという欠点があった。In the conventional magnetic head azimuth adjustment mechanism, the press nut is between the head mounting surface side and the base mounting surface side of the base, so when assembling, first install the differential screw presser and the press nut in the base, and then install the differential screw. Since the pitch of the differential screw is different because the screw must be screwed in, the differential screw retainer must be rotated by an amount that cancels the difference in pitch while rotating the differential screw, and at that time the retainer nut contacts the base. If you cannot move the differential screw retainer and rotate the differential screw without loosening the retainer nut,
There is a drawback that the differential screw may be damaged and that the assembly work takes a long time.

ることができる。FIG. 1 is a sectional view of a magnetic head azimuth adjusting mechanism which is an embodiment of the present invention, and FIG. 2 is a view taken in the direction of arrow A in FIG.
In FIG. 1, the base 2 holding the magnetic head 1 has its head mounting surface side and base mounting surface side connected by a single rib. The tape guides 3 are installed on the base 2 on both sides of the magnetic head 1. One end of the differential screw 4 is screwed into the head mounting surface side of the base 2, and the other end of the differential screw 4 is screwed into a differential nut 5 mounted on the base mounting surface side of the base 2. The differential nut 5 is fixed on the base 2 by a nut retainer 6 attached to a fixing screw portion provided on the base mounting surface side of the base 2. By rotating the differential screw 4 depending on the difference in pitch between the side of the differential screw 4 engaged with the base 2 and the side of the differential screw 5 engaged with the differential nut 5, the base mounting surface and the head mounting surface of the base 2 are changed. The angle changes and the azimuth of the head can be changed and adjusted. Further, on the head mounting surface side of the base 2, an adjustment scale 7 shown in FIG. 2 provided around the differential screw 2 rotates the differential screw by an amount corresponding to the measured angle when adjusting the head azimuth. Can be made.

り、作業時間の短縮ができる効果がある。As described above, in the magnetic head azimuth adjusting mechanism of the present invention, since the differential nut and the nut retainer are attached from the base mounting surface of the base, the differential screw is first installed in the base and then the differential nut and the nut retainer are assembled in this order. No adjustment is required when installing the differential screw, and there is no risk of damage to the differential screw. Further, according to the present invention, the adjustment scale provided on the base facilitates the adjustment work after the azimuth measurement, and has the effect of shortening the work time.
