Abstract

PURPOSE: To easily detach a spindle motor, a slider and a fixed head by making the attaching direction of a base plate opposite to the direction of an optical disk with respect to the base plate, opening an opening part and turning an attaching screw. CONSTITUTION: When the disk is repaired, and when the spindle motor 1, the slider, the fixed head, etc., are detached from an optical disk main body and a first base plate 8, the attaching direction of the base plate 8 is made opposite to the direction of the optical disk with respect to the base plate 8. Then, by opening the opening part, and turning the attaching screw 11, the spindle motor 1, a first slider 6, a second slider 7, a first fixed part 3 and a second fixed part 4 are easily detached.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disk reproducing device.

[0002]

2. Description of the Related Art FIG. 4 is a longitudinal sectional view of an optical disk reproducing apparatus capable of simultaneously recording and reproducing data on both sides of an optical disk. A spindle motor for rotating an optical disc, a first fixed head part 2, and a first slider 6 for moving the first moving head part 4 in the radial direction of the optical disc are fixed to the first base plate 8. There is. The second fixed head portion 3 and the second slider 7 are fixed to the second base plate 9.

FIG. 5 is a vertical sectional view showing a state in which an optical disc is inserted in an optical disc reproducing apparatus. When the optical disc is loaded into the optical disc reproducing apparatus, the first base plate 8 and the second base plate 9 approach the recording / reproducing surface of the optical disc. When the hub of the optical disk is chucked by the spindle motor 1, the optical disk is rotated by the spindle motor. As a result, both sides of the optical disk are in a recording and reproducing state.

[0004]

In the prior art as described above, when the optical disk reproducing device fails, if it becomes necessary to repair it, it is necessary to remove the spindle motor, slider, fixed head, etc. The removal work was very difficult and difficult.

FIG. 6 shows a spindle motor, a slider,
FIG. 3 is a perspective view showing a state in which a fixed head and the like are removed from the optical disk reproducing apparatus main body and the first base plate 8. After removing the exterior plate 12 of the optical disk reproducing device from the main body of the optical disk reproducing device, the first base plate 8 is separated from the second base plate 9. Next, it was necessary to remove the mounting screw 11 for mounting the spindle motor, the slider, the fixed head, etc. on the first base plate 8.

It is an object of the present invention to easily take out parts such as a spindle motor, a slider and a fixed head when repairing an optical disk reproducing apparatus.

[0007]

In order to solve the above problems, the present invention provides a slider for moving a fixed head portion including a spindle motor for rotating an optical disk and a light source and a moving head portion including an objective lens in a radial direction. The fixing means is configured to be attached from the direction opposite to the position where the optical disc is placed.

[0008]

Since the mounting direction of the spindle motor, the fixed head section and the slider to the base plate is opposite to the mounting position of the optical disk with respect to the base plate, the first base plate and the second base plate are attached. Since it is not necessary to separate the plates, the components such as the spindle motor, the slider, and the fixed head can be easily taken out when the optical disc reproducing apparatus is repaired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a longitudinal sectional view of an optical disk reproducing apparatus capable of simultaneously recording and reproducing data on both sides of an optical disk according to this embodiment. FIG. 2 is a vertical sectional view showing a state where an optical disc is inserted in the optical disc reproducing apparatus according to the present embodiment.

A spindle motor 1 which is a rotating means for rotating the optical disk 13, a first fixed head portion 2 and a second fixed head portion 3 including a light source, and a light source (not shown).
First moving head unit 4 and second moving head unit 5 including an objective lens (not shown) that collects laser light emitted from the first moving head unit 4 and second moving head unit 5 The first slider 6 and the second slider 7 for moving the optical disc 13 in the radial direction, the spindle motor 1
And the first fixed head section 2, the first moving head section 4, and the first
For fixing the slider 6 of the second embodiment with the mounting screw 11
The base plate 8, the second fixed head portion 3, the second moving head portion 5, and the second slider 7 are fixed to each other by the mounting screw 11. The mounting screw 11 is attached to the first base plate 8 and the second base plate 9 in the opposite direction to the position where the optical disk 13 is placed, regardless of which base plate is used.

When the optical disc 13 is loaded into the optical disc reproducing apparatus, the first base plate 8 and the second base plate 9 move in a direction approaching the optical disc 13. Then, the spindle motor 1 fixed to the first base plate 8 is fitted with a hub (not shown) at the center of the optical disc 13, and the optical disc 13 is rotated. The first fixed head unit 2 and the first moving head unit 4 record / reproduce on the spindle motor side (lower surface side in FIG. 2) of the inserted double-sided recording / reproducing optical disc 13. The second fixed head unit 3 and the second moving head unit 5 record / reproduce on the opposite side (upper side in FIG. 2) of the inserted double-sided recording / reproducing optical disc 13 to the spindle motor.

FIG. 3 is a perspective view showing a state in which the spindle motor, the slider, the fixed head and the like are removed from the optical disk reproducing apparatus main body and the first base plate 8 in the optical disk reproducing apparatus according to the present embodiment. . Spindle motor, first and second sliders, first and second
Even when removing the fixed head and the like from the optical disc reproducing device, the opening of the main body of the optical disc reproducing device is opened to
Also, they can be easily removed by simply turning the mounting screw 11 fixed to the second base plate.

In this embodiment, the fixed head portion including the light source is fixed to the base plate, but an optical pickup in which the moving head portion and the fixed head portion are integrated may be used.

[0014]

As described above, according to the present invention, the spindle motor, the slider and the fixed head are attached to the base plate in the direction opposite to the optical disc with respect to the base plate. It is possible to easily remove them by opening and opening the spindle motor, the slider, and the fixing screw that fixes the fixed head to the base plate.

Further, the assemblability in the factory is improved, and the effect of cost reduction is sufficient.
