Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a manual cleaner for optical discs such as compact discs and laser discs.

2. Description of the Related Art Conventionally, optical discs have been used to read information such as audio and video by shining a laser beam onto the recording surface of the disc, so it must be kept in a clear state at all times. This is because when used repeatedly or over time, dust, oil, etc. naturally adhere to the surface. Therefore, the user needs to use a cleaner to properly clean the surface. As such cleaners, wet cleaners and dry cleaners are commercially available, so one or both may be purchased and used. In this wet type cleaner, the cleaning body is made of felt that holds a cleaning liquid such as fluorocarbon-based liquid, alcohol, water, etc., whereas in the dry type cleaner, a chamois is used as the cleaning body.

Problems to be Solved by the Invention However, in the case of wet methods, those that use fluorocarbon-based liquids as cleaning liquids have the problem of ozone layer depletion, and self-restraint is requested. However, there is no residue after wiping. Also, with products that use alcohol, water, etc., oils and fats are broken down by these substances and once they float from the surface, they do not evaporate together, so if they adhere to the felt and are not removed along with the dust, they will dry again and return to the surface. remains as a residue.
Since this residue is visible to the naked eye and has a diameter of about 5 μm, recording grooves of, for example, 0.2 μm are blocked and do not reflect light accurately, which impedes reading of the record. In the dry method, fats and oils cannot be completely removed because they are not decomposed. This is because the recording surface is coated with a lacquer-based paint, so if you rub it too hard, the protective film will come off, so you have to rub it only lightly. cannot be removed. However, if you prepare both cleaners and use the dry cleaner immediately after using the wet cleaner, dust and dirt will be removed.
Although both oil and fat can be removed satisfactorily, it is difficult for general users to carry out such cleaning procedures.

The present invention has been made in view of these conventional problems, and it is an object of the present invention to provide an optical disk cleaner that can effectively remove both dust and oil.

Means for Solving the Problems Means for achieving the above object will be described below with reference to FIG. 1, which corresponds to an embodiment.

2 and a dry cleaning body 16, when cleaning, the recording surface is first wiped off using the wet cleaning body 12 at one end, and then a cleaning liquid such as alcohol or water is applied to the recording surface. It can break down the fats and oils that are present.
Therefore, if the surface is quickly wiped again using the dry cleaning body 16 at the other end before the liquid dries, the oil and fat can be effectively removed since it has been decomposed. Note that dust is also well removed by wiping twice. Each of these cleaning bodies 12 and 16 has a corresponding operating end 2.
When 6, 50 and the intermediate portion 38 of the base 10 are pinched with fingers, the push springs 34, 5 interposed therebetween are released.
6, the mouth can be opened using the shafts 30 and 54 as fulcrums, and replacement can be performed. or,
In order to hold the cleaning liquid in the wet cleaning body 12, the cleaning liquid injection hole 22 in the presser end 24 may be used.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 is a front view of an optical disk cleaner according to an embodiment of the present invention, FIG. 2 is a plan view thereof, and FIG. 3 is a perspective view mainly showing the end portion including the wet cleaning body excluding the cover. . In the figure, reference numeral 10 denotes a base made of an elongated rectangular plastic plate having an end 14 for receiving the wet cleaning body 12 and an end 18 for receiving the dry cleaning body 16. Further, 20 has an end portion 24 provided with a cleaning liquid injection hole 22 for pressing the wet cleaning body 12, and an operating end portion 26, and is made of a rectangular plastic plate approximately half the length of the base body 10. 1
It is an actuating member. This first actuating member 20 is
0, and the lower side of the intermediate portion 28 is along the axis 30
It is rotatably supported. Also, the middle part 2
There are two parallel anti-slip protrusions 32 on the top surface of 8.
There is. Note that instead of a pivot support, it is also possible to adopt a so-called pivot structure in which a concave portion or a convex portion of the first actuating member 20 is fitted into a convex portion or a concave portion of the base body 10 and is rotatably supported. A metal push spring 34 is interposed between the base body 10 and the first actuating member 20, which normally closes the mouth formed by the receiving end 14 and the holding end 24. The push spring 34 is, for example, a compression coil spring, and has one end 36 in contact with the inner surface of the intermediate portion 38 of the base body 10, and the other end 40 in contact with the inner surface of the operating end portion 26 of the first actuating member 20,
Further, a shaft 30 is inserted through the center of the winding portion located at the center. Note that the push spring 34 can have various structures, and the contact positions of both ends thereof can be set on the outer surface of the receiving end 14 and the outer surface of the presser end 24, respectively. The mouth made of the receiving end 14 and the presser end 24 is vertically symmetrical in the shape of a crocodile mouth, and a large number of teeth for biting the cleaning body 12 are protruded inside the mouth. Therefore, the base body 10 is further provided with a cleaning liquid injection hole 42 in its receiving end 14 and two parallel anti-slip protrusions 44 in its middle part 38, similar to similar holes in the first actuating member 20. 22 and the protrusion 32 at a symmetrical position.

Further, 46 is a second operating member having an end portion 48 for pressing the dry cleaning body 16 and an operating end portion 50. The second actuating member 46 extends along the base body 10 and is rotatably supported at its intermediate portion 52 by a shaft 54 . Note that a pivot support can be used instead of a pivot support. These base bodies 10 and the second actuating member 4
6 have their receiving end 18 and presser end 48.
A push spring 56 is interposed to normally close the biting opening consisting of. Comparing the structure of the side equipped with such a dry cleaning body with the structure of the side equipped with the wet cleaning body described above, the cleaning liquid injection hole 2
