Abstract

PURPOSE:To securely remove dust piled up on an objective lens without damaging the objective lens of an optical pickup by storing a device which is provided near a cotton ball 13 and which feeds air. CONSTITUTION:When solvent is moistened into the cotton ball 13 and a cassette is set in an optical disk device, the turn table 21 of a motor 22 and the hub 1 of an optical pickup cleaner are coupled. When the table 21 is rotated, bevel gears 2,4,7 and 8 rotate and they rotate the cotton ball 13. A part of the cotton ball 13 is exposed from a long hole 11 to the external part of a cartridge 10. When the objective lens 24 of the optical pickup 23 is set in that place, dust on the lens 24 is removed by the rotation of the cotton ball 13 and an air tube 17 is connected to the other end of an air pipe 15, whereby air 18 is fed by a compressor. Thus, air spouts from a nozzle part and dust on the objective lens 24 is blown away.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an optical pickup cleaner, and more particularly to an optical pickup cleaner that removes dust on an objective lens of an optical pickup of an optical disk device.

[Conventional technology]

Conventionally, in optical disk devices, when removing dust accumulated on the objective lens of an optical pickup, the cover of the device is removed, and then the dust on the objective lens is removed manually using a cotton swab soaked in solvent. had been removed.

[Problem to be solved by the invention]

In conventional optical disk devices, the dust that had accumulated on the objective lens of the optical pickup had to be removed manually after part of the device was disassembled, so cleaning the optical pickup was very time-consuming. be.

Further, since the optical pickup is cleaned manually, the objective lens may be scratched and the internal mechanism of the actuator may be damaged.

Furthermore, for this reason, when cleaning the optical pickup, there is a drawback that the cleaning results vary from person to person.

[Means to solve the problem]

The optical pickup cleaner of the present invention cleans an optical pickup in an optical pickup cleaner for an optical disk device including a driving means for rotating an optical disk medium stored in a storage cassette and an optical pickup for writing and reading data on the optical disk medium. A cleaning member for cleaning, a transmission means for transmitting rotational motion by the driving means to the cleaning member, and a mechanism for feeding air by being laid near the cleaning member are installed in a storage member having an outer diameter similar to that of the storage cassette. It is characterized by having been established.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view of an optical pickup cleaner according to an embodiment of the present invention.

FIG. 2 is a cross-sectional view of the cleaner shown in FIG. 1 set in an optical disc device.

In FIGS. 1 and 2, a cartridge 10 has an outer diameter similar to that of a storage member in which an optical disk medium is stored, is a flat plate, and has a space inside. Inside this space, a hub 1, a bevel gear 2.4.7.8, and a cotton ball 13, which is a cleaning member for cleaning the objective lens 24 of the optical pickup 23, are installed on the shaft 3.
It is held and stored at 6.9.

Further, inside the cartridge 10, an air vibrator 15 is installed and fixed on the inner bottom surface of the cartridge 10 with a stopper 14 so that the nozzle part provided at one end thereof is located near the cotton ball 13. The other end of the air vibrator 15, which comes out from a circular hole 16 provided in the air, is connected to an air tube 17 from a near compressor (not shown) provided outside.

Here, the cartridge 10 has a long hole 11 and a circular hole 12 on its bottom surface, and inside the cartridge 10 there is a hub 1 that is removably connected to the turntable 21 above the circular hole 12, and a hub 1 that is removably connected to the turntable 21 above the circular hole 12. - The bevel gear 2, which has become a body, rotates around the shaft 3.

Further, the bevel gear 2 is engaged with the bevel gear 4 and rotates about a shaft 6. A bevel gear 7 is fixed to the other end of the shaft 6, and as the shaft 6 rotates, the bevel gear 7 rotates.

Further, the bevel gear 7 meshes with the bevel gear 8 and is interlocked with the bevel gear 8.
rotates around axis 9 and reduces its rotational speed. A cotton ball 13 is fixed to the other end of the shaft 9, and as the shaft 9 rotates, the cotton ball 13
also rotates at the same time. Further, the shaft 6 is supported by the support plate 5 and rotates.

Furthermore, since the nozzle section provided at one end of the air vibrator 15 is located near the cotton ball 13, the air tube 17
Air 1 sent from the near compressor via
8 is the optical pickup 2 from the nozzle part of the air vibrator 15.
The liquid is ejected onto the objective lens 24 of No. 3.

In the optical pickup cleaner having the internal structure as described above, when a cotton ball 13 is moistened with a solvent and a cassette is set in an optical disk device, the turntable 21 of the motor 22 provided in the optical disk device and the optical pickup cleaner are connected to each other. The hub 1 is connected. Here, when the turntable 21 is rotated, the rotation is transmitted from the bevel gear 2 to the bevel gear 4 as described above, and the rotation is transmitted from the bevel gear 2 to the bevel gear 4. The bevel gear 7 rotates.

The rotation of the bevel gear 7 causes the bevel gear 8 meshing with the bevel gear 7 to rotate at a reduced speed, thereby rotating the cotton ball 13.

Here, since a part of the cotton ball 13 is exposed to the outside of the cartridge 10 through the elongated hole 11, if the objective lens 24 of the optical pickup 23 is set in that place in advance, the cotton ball 13 The rotation of the objective lens 24
After the dust on the top is removed, the air tube 17 is connected to the other end of the air vibrator 15 and the air 18 is supplied with a compressor.
By blowing air, air is ejected from the nozzle portion, blowing away dust on the objective lens 24, and cleaning the objective lens 24.

〔Effect of the invention〕

As explained above, a cotton ball for cleaning the objective lens of an optical pickup is placed inside a cartridge similar to the storage member in which an optical disk medium inserted into an optical disk device is stored, and a cotton ball is attached to the cotton ball to clean the objective lens of the optical pickup. The objective lens is always cleaned by the same movement of the cotton ball by housing the hub and bevel gears for transmitting the rotational motion of the turntable, and the mechanism for feeding air by placing it near the cotton ball. This has the effect that dust accumulated on the objective lens of the optical pickup can be easily and reliably removed without damaging the objective lens of the optical pickup.

Furthermore, since the cleaning is performed mechanically without relying on manual labor, there is an effect that there are no individual differences in the cleaning results.
