In the figure, 1 is an objective lens, 2 is a cylindrical lens holder, 3 is a base body, and 4a and 4b are lenses. These are two leaf springs whose both ends are fixed to the holder 2 and the base 3, respectively. A coil 6 is wound around a winding frame 5 fixed to the lens holder 2. In addition, 7 is the lens holder 2
The cup-shaped yoke has a central ball with a central hole through which a magnet is inserted, and a ring-shaped magnet 8 is provided on the periphery of the cup-shaped yoke. The yoke 7 and the magnet 8 are provided and fixed on a mounting plate 9 screwed to the base body 3.

The incident light is separated from the incident light by a beam splitter (not shown) and is made to enter the light receiving element. By supplying this reflected light to a cylindrical lens, the amount and direction of the focus shift are detected, and a focus error signal is supplied to the above-mentioned coil 6, so that the objective lens 1 and the lens The holder 2 is integrally displaced in the vertical direction.

The leaf springs 4a, 4b have the function of creating a neutral point during displacement operation;
There is a primary resonance frequency 0 unique to b. Now the first

バネ系の変位の周波数特性である。 From the above formula, the resonance frequency 0 is determined by m and k, and Q in the secondary system is generally 10 to 205
[dB/oct] For example, it is 20 [dB/oct], which is quite large and has a negative effect on the stability system of focus servo operation. FIG. 2A shows the frequency characteristics of the displacement of the spring system in the conventional support device.

とが固着される。 Therefore, the present applicant has previously proposed an optical system support device that provides a sufficient damping effect. This will be explained below with reference to FIG. In addition, in FIG. 4A, illustration of the electromagnetic force generating section for displacing the lens holder 2 shown in FIG. 1 is omitted. Leaf springs 4a, 4b
Polymer compounds 11a and 11b having damping properties are deposited so as to cover one side of each of the substrates, and vibration damping members each having an L-shaped cross section are attached to the corner portions where the polymer compounds 11a and 11b contact the base 3. 12
a, 12b are provided to constitute two leaf springs 4A, 4B for supporting the lens holder 2 with respect to the base body 3. In this case, the lower surfaces of the damping members 12a, 12b and the upper surfaces of the polymer compounds 11a, 11b are fixed, and the back surfaces of the damping members 12a, 12b and the base 3
is fixed.

果を得ることができる。 The leaf springs 4a, 4b are made of stainless steel or amorphous metal and have a thickness of 50 μm, and the damping members 12a, 12b are made of the same material and thickness as the leaf springs 4a, 4b. It is something. Moreover, as the polymer compounds 11a and 11b, 0.6 [mm] to 0.9
Butyl rubber or silicone rubber with a thickness of [mm] can be used. In addition to this, an adhesive having damping properties may be applied. Examples of materials that have such adhesive properties include acrylic alkyl ester flexible resins. Since the parts of the polymer compounds 11a and 11b located below the damping members 12a and 12b are prevented from moving together with the leaf springs 4a and 4b, the internal loss is lower than in other parts. Becomes large.
In other words, the vibrations of the leaf springs 4a, 4b cause internal friction in the polymer compounds 11a, 11b, which generates thermal energy and absorbs the vibrations. Therefore, as is clear from the frequency characteristics in Fig. 5, the Q of the secondary spring system is, for example, 6.
It can be reduced to about [dB], and a sufficient vibration isolation effect can be obtained.

a and 12b are provided so as to suppress movement of the polymer compounds 11a and 11b following the vibrations of the leaf springs 4a and 4b. However, as in the configuration shown in FIG. 4 or FIG.
By providing , the damping effect becomes slightly better,
Also, the compliance of the moving parts does not decrease.
また、制振部材12a,12bをレンズホルダ

One end of each of the leaf springs 4A and 4B, which have a three-layer structure with a
It may be fixed to. In the configuration shown in FIG. 8, since the vibration modes of each of the two leaf springs 4a, 4ba'; 4b, 4b' of the two laminated leaf springs 4A, 4B do not completely match, one serves as a damping plate for the other, so there is no need to provide a damping member having an L-shaped cross section as described above.

することができる。 Therefore, the optical system support devices shown in FIGS. 4, 6, 7, and 8 have a plate spring coated with a polymer compound having damping properties, and a vibration damping member provided thereon. Since the leaf spring is constructed using a simple structure, the Q of the spring system that supports the optical system can be sufficiently damped, and if these are applied to the objective lens support device in an optical disc playback device,
It is possible to prevent the focus servo operation from becoming unstable.

Alternatively, the optical system support device described above may be applied to a leaf spring used when the optical axis of the objective lens can be displaced in the direction of extension of the signal track for time axis correction. Further, the above-described optical system support device can be applied not only to an objective lens but also to support devices such as a beam splitter and a mirror.

簡単に作ることができる。 According to the present invention described above, in a method for manufacturing a plate spring for an optical element driving device in which an optical element is attached to a base by a plate spring, a polymer compound group having damping properties is formed on a first spring base material. After the second spring base material was laminated so as to sandwich the polymer compound base material with the first spring base material, the leaf spring was obtained by punching out the desired shape. Since the vibration modes of the first and second leaf springs do not match, one of them serves as a restraining plate for the other, making it possible to easily and reliably use the leaf spring of an optical element drive device that provides a good damping effect. can be made to
