Abstract

PURPOSE:To obtain a titled magnetic head which requires no spring, has reduced the number of parts, can be fitted easily, and can control an azimuth angle exactly, by cut-setting and forming an elastic bent-up piece on a fitting leg itself of the magnetic head. CONSTITUTION:A fitting leg 2 is made of a metallic plate. A bent-up piece 8 is cut-setting downward, and on the bent-up piece 8, a bent-up part 8a as shown in figure is formed. A distances H between the lower face of the bent-up part 8a and the lower face of the fitting leg 2 is made larger than height (h) of the head mount. The fitting leg 2 is fixed to a shielding case 1 by a support 4 as shown in the figure, and the bent-up 8a is brought into contact with a chassis 9 of the side of a device body. As a result, the bent-up piece 8 becomes a bent state, and the free end side of the fitting leg 2 is in a higher state than (h), therefore, an azimuth angle theta is in a state which has been shifted by C. The azimuth angle can be controlled to ''0'' by lowering the free end side of the fitting leg 2 by use of a screw 3.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic head, and more particularly to a magnetic head with an improved azimuth adjustment mechanism.

Generally, a magnetic head has a shield case 1 as shown in FIG. 1, and a mounting leg 2 is fixed to the lower part of the shield case 1 by welding or screwing. In that case,
The magnetic head is fixed to the main body of the apparatus via the mounting legs 2.

That is, each of the supporting legs 2 has a long hole 2a formed therein, and one of the legs 2 is connected to a support 4 protruding from the main body of the device with a screw 3 as shown in FIG. By fixing the other end of the leg 2 with the screw 3 via the spring 5, and adjusting the screw according to the spring 5 rule, one end of the leg 1 can be adjusted up and down, so that it is tilted to the axis of the magnetic recorder. In the perpendicular direction, the gap G of the magnetic head,
, eliminate the deviation of the angle θ-C1, that is, the azimuth angle, between G2 and the straight line a extending 1η, and
-・0 Adjustments are being made to ensure that the results are correct.

In conventional equipment that uses this type of notification,
The presence of the spring 5 becomes an indispensable element, and the number of parts increases accordingly. There was a drawback.

The present invention has been made to eliminate the following drawbacks of the conventional technology. , f, I am miserable and can adjust the azimuth angle inside the cylinder, \ro,
The object of the present invention is to provide a magnetic head having two configurations.

In the present invention, in order to achieve the object stated in -1-,
A structure is adopted in which the mounting leg itself is formed by cutting and raising a bending piece that has elasticity, and the azimuth angle can be adjusted using the elasticity of the bending piece.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

Figures 4 to 7 illustrate one embodiment of the present invention.
In each figure, the same parts as in Figures 1 to 3 are designated by the same reference numerals.
The explanation will be omitted.

In this embodiment, the mounting leg 2 is made of a metal plate, for example, SUS.
As shown in FIG. 4, an elastic material such as 304-C5P 44 is used to form a substantially rectangular shape, and an opening 7 is formed in the center along the longitudinal direction.
! 'Rji! The bent piece 8 is cut and raised downward as a continuation of 7a, and a bend H (58a) is formed in the horizontal direction at the free end of this bent piece 8.The lower surface of this bent part 8a The distance between the lower surface of the mounting leg 2 and (3) is set to be larger than the head mount height 1, which will be described later.

In addition, on one side of the receiving leg 20, there is a shield case 1.
For fixing against? A huff 1) is formed.

When the mounting leg 2 having such a structure is fixed to the shield case 1, the - of the mounting leg 2 is fixed as shown in FIG.
.

Then, as mentioned above, since the head mount I/length 11 is smaller than the distance H between the lower surface of the bent portion 8a and the lower surface of the take-up leg 2, the bent piece 8 is bent and in this state. As is clear from FIG. 6, since the free end side of the mounting leg 2 is higher than 11, the azimuth angle θ is offset by C.

Then, insert the screw 3 into the through hole 2a on the 1'' 1 end side of the mounting leg 2, tighten the screw against the shaft 9 (4), and lower the mounting leg 2 to the free end side. For example, the bending piece 8 can be bent to adjust the azimuth angle to θ-0.

Since this embodiment is constructed as follows, there is no need for a separate spring as in the conventional case, and the mounting leg itself is provided with an elastic bending piece, so the number of parts is small. It is easy to install, and the azimuth angle can be adjusted reliably.

8 and 9 explain other structural examples of the mounting leg 2. In the example shown in FIG. 8, a protrusion 8b is provided on the lower surface of the bent portion 8a by pressing or the like. The 9th
In the example shown in the figure, a downwardly projecting piece 8c is formed at the tip of the bent portion 8a.

Even if the structures shown in FIGS. 8 and 9 are adopted, the same effects as those of the above-mentioned embodiments can be obtained, and the spring effect can be further enhanced.

As is clear from the following explanation, according to the present invention, the mounting leg of the magnetic head itself is formed by cutting and raising an elastic bent piece, so there is no need for a separate spring as in the conventional case. Why? It is possible to obtain a magnetic head that reduces the number of rlli products, is easy to install, and can reliably adjust the azimuth angle.
