行っている。For example, as shown in Figure 6, a rotary head type VTR device has a rotary head partially attached to the outer periphery of a rotary cylinder (2) arranged with its rotary axis inclined with respect to the running direction of the magnetic tape (1). Take the magnetic head (3) (-1) and insert the diagonal storage trunk (4) as shown in Figure 7, which is provided on the magnetic tape (1) that runs by rotating the rotary cylinder (2) at a constant speed. 4) - The recording is played back by sequentially scanning the magnetic head (3) above.In this VTR device, the running speed of the magnetic tape (1) is doubled or tripled to perform a picture search. In this case, since the rotary cylinder (2) rotates at a constant speed, the magnetic head (3) will not accurately scan over the recording trunk (4) (4L) as shown by the dotted line in FIG. This generates noise and causes disturbances in reproduced images. Therefore, when performing a picture search, tracking adjustment is performed to move the magnetic head (3) in a direction that corrects the positional deviation.

さに応じるもので、磁気ヘッド（３）を４００μｍ程度
変位させるには約５００■の電圧が必要とされている。In order to perform the tracking correction described above, it is necessary to displace the magnetic head by a maximum of about 400 μm when playing at 8x speed, and a bimorph type piezoelectric element (piezoelectric ceramic element) that uses piezoelectric transverse effect is used as a device to perform such correction. Commonly used. As shown in FIG. 8, one end of the long bimorph piezoelectric element-f(5) is fixed to
), and a magnetic head (3) is fixed on the other end, and when a voltage is applied to the piezoelectric element (5), the piezoelectric element (5)
The magnetic head (3) on the M end side bends around the fixed base (6) as a fulcrum.
) is displaced. The amount of displacement depends on the magnitude of the applied voltage, and approximately 500 μm of voltage is required to displace the magnetic head (3) by approximately 400 μm.

量が得られなくなる問題があった。However, although such a bimorph type voltage element has the advantage of a simple structure, the driving voltage is as high as 500 V at maximum, and distortion is multiplied by M due to repeated driving. , there was a problem that the same amount of displacement could not be obtained with the applied voltage.

トラッキング補正に利用できない。As a solution to the above-mentioned problems, there is a method in which a laminated piezoelectric single element utilizing a piezoelectric longitudinal effect is used as a displacement source of a magnetic herad instead of a bimorph piezoelectric element. The drive voltage of this laminated piezoelectric element is low, and there is almost no distortion, but the amount of displacement of the laminated piezoelectric element itself is small, about 10 μ at maximum, and tracking of VTR equipment is required unless a displacement magnifying device is attached. Cannot be used for correction.

is a displacement amplifying device, which is composed of a chevron-shaped plate-shaped buckling spring (9) whose both ends are fixed to both vertical ends A and B of a piezoelectric element (7). A magnetic head (3) is fixed on the center portion of the buckling spring (9), which corresponds to the chevron-shaped top.

Both ends move in the direction of opening, and this movement is magnified to create a buckling spring (

。Points to consider The displacement magnification device (8) described above is seen as promising as a device that takes advantage of the advantages of the laminated piezoelectric element (7), but its displacement magnification rate is low and it is actually used in tracking correction devices of VTR devices. When using the piezoelectric element (7) and the buckling spring (9),
It is necessary to install another displacement amplification mechanism that uses the lever principle to amplify the displacement of the piezoelectric element (7) and transmit it to the buckling spring (9), which causes the problem that the entire device becomes larger and more complicated. there was.

A generally elliptical cylindrical spring member with an elliptical or diamond-shaped cross section that surrounds the piezoelectric element with two opposing points in the long axis direction fixed at both ends of the element in the longitudinal direction, and one of the two points in the end axis direction of this spring member is fixed. and a fixing means for

(11) is a displacement magnifying device according to the present invention, which includes one endless band-shaped cylindrical spring member (12) with a substantially elliptical cross section, and two points p, , P4 in the end axis direction of the spring member (12). It is comprised of a fixing means (13) for fixing one point P3 within.

はαより大きく、この拡大原理は第９図の変位拡大装置
の拡大原理と同じである。The fixing point P3 of the spring member (12) is fixed to the rotating cylinder of the V T'R device via fixing means (13). Thus, when a voltage is applied to the piezoelectric element (10), the piezoelectric element (10)
10) extends in the vertical direction, and if the total length of this extension is 2α, the piezoelectric element (10) has both ends A as shown by the solid line in Fig. 3.
``, B'' are both extended by α. Here now Pl and 23
Assuming that the lengths between P3 and 1)2, between P2 and 24, and between P4 and Pl are the same and constant, the amount of elongation (displacement) 2α of the piezoelectric element (10) as shown in FIG. The piezoelectric element (10) moves toward the point P3 with a displacement amount β corresponding to . This displacement amount β
is larger than α, and this expansion principle is the same as that of the displacement expansion device shown in FIG.
一方、バネ部材（１２）の磁気ヘッド（３）が固定され

ができる。On the other hand, the free point P4 to which the magnetic head (3) of the spring member (12) is fixed is also displaced by the same displacement amount β according to the elongation amount 2α of the piezoelectric element (10), but in the case of point P4, the piezoelectric element ( 1
0) itself has been displaced by β, resulting in a displacement of 2β. Therefore, compared to the conventional product shown in FIG. 9, the product of the present invention can displace the magnetic head (3) at twice the magnification rate with the same driving voltage, and can also displace the magnetic head (3) with the same displacement as the conventional product shown in FIG. 3) If you want to move rgA? The voltage can be reduced.

If an even larger magnification is required, for example, as shown in FIG.
5) is fixed with P5 at the center of the plate (
15)! ! 3. Fix one end near P5 to the fixing base (16)
A displacement body (17) such as a magnetic head is fixed on the free end farther from point P5. Then, due to the displacement of the point P4 of the spring member (12), the flat plate (15) swings around the fixed base (16>), and the displacement of the point P4 is further expanded by the lever principle, and the displacement body (17) communicated.
