It is formed by a letter-shaped notch.

[0004] One end of each of the four wires W is disposed across the first and second filling portions 54 and 55, and each wire W is
The first filling portion 54 is in contact with the V-shaped bottom, and the second filling portion 55 is apart from the U-shaped bottom. In this state, an ultraviolet-curing soft elastic adhesive 56 is provided in the first filling portion 54 to hold the wire W in the first filling portion 54, and the second filling portion 55 is provided with an ultraviolet-curing type adhesive. A damper agent 57 made of a silicon-based gel-like damping material is provided to suppress vibration.

Further, a lens holder 59 made of a synthetic resin molded product for holding the lens 58 has a mounting portion 60 for mounting the lens 58 and a holding portion 61 for holding the wire W. The mounting part 60 and the holding part 61 are integrally formed by a molded product. Then, the holding unit 61
Are a top 61a, a bottom 61b, a front and a rear 61c, 61
d, and has a rectangular shape with left and right side surfaces 61e,
A part of the left and right side surfaces 61e is notched over the front and rear portions 61c and 61d, and a pair of wire mounting portions 62 are provided above and below the both side surfaces 61e.

[0006] The wire mounting portion 62 is formed along the wire W to be mounted.

A cylindrical bobbin 64 made of a synthetic resin molded product is provided with a focusing coil 65 wound around the outer periphery thereof, and a tracking coil 66 provided at a front portion thereof. And such a bobbin 64
Is attached to the support member 51 by appropriate means with its bottom placed on the support member 51. The yoke member 67 made of a magnetic material has a U-shaped yoke portion 67.
a, and a yoke portion 67 b having a plate shape. The yoke member 67 has a U-shaped yoke portion 67 a attached to the lens holder 59. Then, the U-shaped yoke portion 67a
The yoke member 67 is formed by projecting a part of the upper part from below the hole of the bobbin 64 and attaching a plate-shaped yoke part 67b to an open part of the U-shaped yoke part 67a.

A rectangular magnet 68 is attached to a U-shaped yoke 67 a located in the hole of the bobbin 64, and is movable with respect to the coils 65 and 66. The coils 65 and 66, the yoke member 67, and the magnet 68 form an electromagnetic drive mechanism. In the conventional optical pickup having such a configuration, the current flowing through the focusing coil 65 of the electromagnetic drive mechanism is used to support the wire W having the first filling portion 54 of the wire mounting portion 53 of the fixing member 52 as a supporting portion. The lens holder 59 is driven in the focusing direction with the lens 58, and the lens holder 59 is driven in the tracking direction with the lens 58 by the current flowing through the tracking coil 66.

The vibration in the focus direction and the tracking direction of the lens holder 59 is suppressed by the damper agent 57 provided in the second filling section 55, and the soft elastic bonding provided in the first filling section 54. The agent 56 suppresses vibrations such as yawing and pitching, particularly in the tangential direction (axial direction of the four wires W).

Next, a method of assembling the wire W of the optical pickup will be described. First, a bobbin 64 provided with coils 65 and 66 is attached to the support member 51, and a lens 58 is provided.
The yoke member 67 is attached to the lens holder 59 provided with. The semi-finished product in which the yoke member 67 is combined with the bobbin 64 is prepared. Next, such a semi-finished product is held by a jig (not shown) with one side surface 52e, 61e of the fixing member 52 and the holding portion 61 downward, and the other side surface 52e, 61e is positioned upward. State. Next, 2
The wire W is put over the wire attachment portion 53 of the fixing member 52 and the wire attachment portion 62 of the lens holder 59, and the wire W is placed on the V-shaped bottom of the wire attachment portions 53 and 59.

Next, the first filling portion 54 of the fixing member 52 and the wire mounting portion 61 of the lens holder 59 are filled with adhesives 56 and 63, and the second filling portion 55 is filled with a damper agent 57. . Thereafter, the adhesives 56 and 63 and the damper agent 57 are irradiated with ultraviolet rays to be cured, thereby completing the attachment of the two wires W on one side. Next, the semi-finished product is turned over, and the fixing member 52 and the holding portion 6
The side surfaces 52e, 61e to which the one wire W is attached are held downward by a jig (not shown), and the side surfaces 52e, 61e, to which the wire W is not attached, are positioned above. After that, the two wires W are mounted by the same procedure as the above-described mounting method, and the mounting of the other two wires W is completed. Thus, the attachment of the four wires W is performed.

The fixing member 52 and the bottom 5 of the holding portion 61
2b, 61b with the fixing member 52 and the holding portion 6
When the wire W is placed on the wire mounting portions 53 and 62 and the adhesives 56 and 63 are filled in a state in which the wires 1 are set up, that is, as shown in FIG. The walls 54a, 62a extend from the side surfaces 52e, 61e to the upper portion 52a,
Since the wire W is inclined toward 61a, the wire W falls off the side surfaces 52b, 61b, and the adhesive 56,
Since the wire 63 hangs down from the side surfaces 52e and 61e, the semi-finished product is turned over and the wire W is attached as described above.

[0013]

Since the conventional optical pickup has a structure in which the first and second filling portions 54 and 55 are arranged side by side on the fixing member 52, the adhesive filled in the first filling portion 54 is used. There is a problem that the damper agent 57 filled in the second filling portion 55 and the damper agent 57 are mixed, so that the adhesion to the wire W and the function of the damper are deteriorated, and the damping function in the tangential direction is deteriorated.

[0014]

Means for Solving the Problems As a first means for solving the above-mentioned problems, a fixing member for attaching a wire is provided, and the fixing member is partially cut away along the wire. A formed wire attachment portion is provided, wherein the wire attachment portion includes a first filling portion and a second filling portion formed along the wire, and a separation portion provided between the first and second filling portions.
