Abstract

PURPOSE:To easily and uniformly remove dust on the objective lens of an optical pickup by providing fixedly a cleaning member at a rotary shaft terminal part, and providing a means to splash gas in the neighborhood of the cleaning member. CONSTITUTION:A cotton ball 5 provided fixedly at the lower terminal part of a shaft 7 coupled with a wheel 4 is rotated with the rotation of a wheel 2 via a belt 3 with the shaft 7. Since the cotton ball 5 is exposed to the outside of a cartridge 10 over a slot hole 11, the dust on the objective lens 24 can be removed by the rotation of the cotton ball 5 by setting the objective lens 24 of the optical pickup 23 so as to be positioned at that part. Separately from that, the air is exhausted from a nozzle part by connecting an air tube 17 to the other end of an air pipe 15 and blowing the air with a compressor, etc., in a direction of arrow head 18, thereby, the dust on the objective lens 24 can be removed. In such a way, it is possible to easily and surely remove attached dust without impairing the objective lens of the optical pickup.

Description

TECHNICAL FIELD The present invention relates to an optical pickup cleaner, and more particularly to an optical pickup cleaner that removes dust attached to an objective lens of an optical pickup.

PRIOR ART Conventionally, when removing dust adhering to the objective lens of an optical pickup, a part of the optical disk device was disassembled and the removal was carried out manually using a cotton swab soaked with a solvent.

Such manual cleaning is very time-consuming and has the drawback of damaging the objective lens and damaging the internal mechanism of the actuator.

Purpose of the Invention The present invention has been made to eliminate the above-mentioned drawbacks, and provides an optical pickup cleaner that can easily and reliably remove dust attached to the objective lens of the optical pickup without damaging the objective lens. The purpose is to provide.

Structure of the Invention The first pickup cleaner according to the present invention is an optical pickup cleaner for an optical disk device, which includes a driving means for rotating an optical disk medium stored in a storage cassette, and an optical pickup for reading and writing data to and from the optical disk medium. A cleaning member for cleaning the optical pickup, a transmission means for transmitting rotational movement by the driving means to the cleaning member, and a means for blowing gas near the cleaning member are provided in the storage cassette. Features.

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

Figure m1 is a perspective view including a partial cross section of an embodiment of the present invention;
FIG. 2 is a configuration diagram of an embodiment of the present invention when viewed from the side.

The optical pickup cleaner of this embodiment has a cassette structure and is large enough to be inserted into an optical disc device.
A circular hole 12 is provided to obtain driving force from the turntable, and an elongated hole 11 is provided to clean the objective lens of the optical pickup.

The hub 1 and the wheel 2 are concentrically connected and rotate about an axis 6.

The belt 3 transmits the rotation of the wheel 2 to the wheel 4, which rotates around an axis 7.

A cotton ball 5 is fixed to the lower end of the shaft 7, and the cotton ball 5 is attached to the cassette 1.
A long hole 11 is provided so as to be exposed from 0, and the length of the shaft 7 is adjusted so that the cotton ball 5 comes into contact with the objective lens 24 of the optical pickup when the cassette 10 is installed in the main body of an optical disk device (not shown). It is.

Furthermore, the air vibrator 15 is installed and fixed on the inner bottom surface of the cassette 10 by means of the first fitting 13 so that the nozzle section provided at one end thereof is located near the cotton balls 5, and the other end is fixed to the inner bottom surface of the cassette 10. It is laid and fixed to the internal bottom surface of the cassette 10 by a stopper 14 so as to be located in a circular hole 16 provided on the side surface.

This air vibe 15 is connected to a compressor (not shown) via an air pipe 17.

Next, the operation will be explained.

After moistening the cotton ball 5 with the solvent, when the cassette 10 is inserted into the optical disc device, the turntable 21 of the motor 22 provided in the optical disc device is connected to the hub 1 of the optical pickup cleaner. When the turntable 21 is rotated, the hub 1 rotates, and the wheel 2 rotates around the shaft 6 to which the hub 1 is fixed.

The rotation of the wheel 2 causes the wheel 4 to rotate through the belt 3. The cotton ball 5, which is fixed to the end of a shaft 7 connected to the wheel 4, rotates together with the shaft 7.

Since the cotton ball 5 is exposed to the outside of the cartridge 10 through the elongated hole 11, if it is set so that the objective lens 24 of the optical pickup 23 is placed at that location, the rotation of the cotton ball 5 will cause the cotton ball 5 to move onto the objective lens 24. dust is removed.

Separately, an air tube 1 is attached to the other end of the air vibrator 15.
By connecting 7 and blowing air from a compressor or the like in the direction of arrow 18, air is ejected from the nozzle portion and dust on the objective lens 24 is removed.

Note that the rotation speed of the cotton balls can be changed depending on the diameters of the wheels 2 and 4, and the cleaning effect is higher when the cotton balls are rotated slowly.

Although cotton balls are used as an example of the cleaning material, other materials include silicone cloth and Shinbon paper in addition to cotton. Although the shape is preferably spherical, it is also possible to form it into a disk shape or a cylinder shape depending on the diameter of the objective lens. Furthermore, by providing the support for fixing the cleaning member 5 closer to the outer periphery than the shaft 7, it is possible to accommodate lenses with large diameters.

Furthermore, if an antistatic agent or the like is mixed into the air ejected from the air vibrator 15, it is possible to prevent static-charged dust from entering the main pipe of the pickup section.

Alternatively, a structure may be adopted in which air is blown near the pick amplifier section using the rotational force of the wheel 4.

As described in detail, the optical pickup cleaner of the present invention can be inserted into a previous disk device, and includes means for transmitting information from the rotation shaft of the turntable of the optical disk device to another rotation shaft, and By fixing a cleaning member in the optical pickup and providing means for blowing gas near the cleaning member, there is an effect that dust on the objective lens of the optical pickup can be easily and uniformly removed.
