Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disc cleaner for cleaning the information recording surface of an optical disc or the like.

[Conventional technology]

Optical discs on which information is recorded are usually housed in cartridges, and the information recording surface is protected from external dust or direct contact with human hands. However, with long-term use, there is a problem that dust may enter the cartridge and adhere to the information recording surface, which adversely affects information recording and reproduction. Therefore, it is required to periodically clean the information recording surface of the disc.

Various devices for this purpose have been proposed, such as JP-A-63
In Japanese Patent No. 106978, it has been proposed to use a belt-shaped brush, which involves attaching a brush to an endless belt and bringing the brush into contact with the recording surface of a rotating disk to control the heald. It cleans while rotating.

Further, Japanese Patent Application Laid-Open No. 63-244456 proposes a device in which a felt-like cleaning member is brought into pressure contact with the information recording surface of a rotating disk to perform cleaning. Further, Japanese Utility Model Application Publication No. 61-199784 proposes a device for removing dust by blowing ion wind onto the information recording surface of a rotating disk.

[Problems to be Solved by the Invention] By the way, the above-mentioned conventional device has the following problems. First, 1. The second device is designed to avoid the possibility that when replacing a cleaning member such as a brush with a new one, by grasping the new cleaning member, the grease or dust on the person's hands will adhere to the new cleaning member. There's a problem. Further, in both cases, since the same heald or cleaning member is used continuously for a certain period of time, there is a risk that dust and the like will accumulate and conversely stain the information recording surface.

The third device has a drawback in that dust and the like attached to the information recording surface of the disk cannot be completely removed using ion wind alone.

The present invention has been made in view of such circumstances, and by using a tape-shaped cleaning member and having a structure that allows it to be automatically rolled up, the cleaning member can be rolled up without touching the human hand. To provide a disk cleaner that can reliably clean the information recording surface of a disk by preventing the accumulation of dirt and dust when it is renewed.

[Failure to solve the problem]

The disc +J according to the present invention is configured such that, while the disc is rotated by the rotating means, the tape-shaped cleaning member wound around the first glue S is wound around the second reel by the winding means. Alternatively, before or after cleaning, a certain amount of the disk is wound up and the stretched portion is brought into contact with the information recording surface of the disk for cleaning.

[Effect]

Since the disk is not rotated by a rotating means, a tape-shaped cleaning member is brought into contact with the information recording surface to clean it. The abutting part of this tape-like cleaning part is a tension part between the first and second reels, and the tape-like cleaning member is wound on the second reel continuously during cleaning, or before cleaning. Cleaning is carried out by a cleaning member that constantly moves to unused parts.

[Embodiments of the invention]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on drawings showing embodiments thereof. FIG. 1 is a perspective view showing the internal structure of a disk cleaner according to the present invention (hereinafter referred to as the device of the present invention).

A motor 3, which is the rotating means, is disposed in the center of the main body of the apparatus, and rotates the optical disc 1 by adsorbing a clamping hub (not shown) of the optical disc 1 housed in the cartridge 2. A cleaning mechanism 4 is disposed on the side of this and below a shutter (not shown) of the cartridge 2. The cleaning mechanism 4 is composed of a cassette 5 including a wiper material 53, which is the tape-shaped cleaning member, and a drive section 6 into which the cassette 5 is loaded and causes the information recording surface of the optical disc 1 to be cleaned. The cassette 5 has substantially the same configuration and shape as a compact cassette for recording audio, etc., and includes two reels 51 and 52. In this embodiment, a wiper is wound on the reel 52 (first) in advance. The material 53 is wound onto a reel 51 (second). Wiper material 5 on two reels 5152
The tension portion 3 is exposed at the center of one side 54 of the cassette 5 to the outside of the cassette. As the wiper material 53, woven fabric, ultra-fine fiber (for example, Kanebo @ I SAν
INA MINT former X, East @ I'1rRACI'1
EATION) etc. can be used, and the width can be set to 10~
It was processed into a tape shape with a length of 15 m.

The drive unit 6 is configured to load the cassette 5 with the side surface 54 of the cassette 5 facing the disk l in parallel, and with its elongated direction orthogonal to the radial direction of the optical disk 1. The upper part of the drive section 6 is provided with a contact section 61 for slightly pulling out the wiper material 53 in the exposed portion of the cassette 5 to the outside of the cassette and abutting it on the information recording surface of the optical disk 1. This abutting portion 61 is configured to move the abutting element 62 in a direction perpendicular to the surface of the optical disk using, for example, a solenoid, and lift the wiper member 53 from the back side by the abutting element ε2. Then, the front surface side is brought into contact with the surface of the optical disc 1 to be cleaned.

The drive section 6 is connected to the reel 5L52 of the loaded cassette 5, and incorporates a winding section 63 serving as the winding means for rotating the reel 51 in the direction of the arrow. The lower portions of both sides of the drive unit 6 are provided with rails 64. which are arranged parallel to the radial direction of the optical disc 1, respectively. ．． The optical disc 1 is inserted into and supported by the cassette 64, and the optical disc 1 is inserted and supported by a drive mechanism (not shown) with the cassette 5 loaded.
It is possible to move in the radial direction.

Reference numeral 7 in the figure indicates an ionized air generating section provided on the side substantially opposite to the cleaning mechanism 4 in the motor 3. By blowing the ionized air generated as shown in FIG. In this example,
This may be configured to be used in conjunction with the cleaning operation by the cleaning mechanism 4, but it is not necessarily necessary to provide this, and is effective in cases where a large amount of static electricity is generated due to the material of the optical disc 1, etc.

Next, a procedure for cleaning the optical disc 1 using the apparatus of the present invention configured as described above will be explained. First, cartridge 2
As the optical disk 1 housed in the cartridge is loaded into the device, the shutter and cover on the bottom side of the cartridge and the tray 2 are locked in an open state, and a part of the information recording surface of the optical disk 1 can be accessed from the shutter opening. be exposed. At the same time, optical disc 1
The optical disc 1 is supported by suction on the clamping hub of the motor 3 or the rotating shaft of the motor 3, and the optical disc 1 can be rotated in the direction of the arrow. At this time, the drive unit 6 of the cleaning mechanism 4 is positioned closest to the motor 3 on both rails 64.

Now, when the above-mentioned operation is completed, the motor 3. Cleaning mechanism 4
and the ionized air generating section 7, respectively, to generate the optical disc 1.
Start cleaning the information recording surface.

That is, the optical disc 1 is rotated by the motor 3, and ionized air generated by the ionized air generating section 7 is blown onto the information recording surface of the optical disc 1. Then, in the drive section 6, the wiper material 53 is brought into contact with the inner peripheral portion of the information recording surface of the optical disk 1 by raising the contact element 62 at the contact section 61. At the same time, the winding section 63 rotates the reel 51 at a slow speed in the direction of the arrow, thereby winding up the wiper material 53 little by little from the reel 52 to the reel 51. Furthermore, the drive unit 6
is moved along both rails 64 in a direction away from the motor 3. Through these operations, the information recording surface of the optical disk 1 is cleaned from the inner circumference to the outer circumference by the wiper material 53 that is brought into contact with the abutting element 62, and at the same time, the information recording surface of the optical disk 1 is also rotated. The entire surface will be cleaned. At this time, the wiper material 53 is wound up little by little, so it is always transferred to the unused portion of the wiper material 53, and as in the conventional device, the removed dust and the like are deposited continuously. There is no cleaning required.

Furthermore, when the driving section 6 is moved to the position on both rails 64 that is farthest from the motor 3, that is, when the cleaning of the outermost peripheral part of the information recording surface of the optical disk 1 by the wiper material 53 is completed, the contact section 61 to lower the abutting element 62 and remove the wiper material 53.
The information recording surface of the optical disc 1 is damaged. In this state, the drive unit 6 is again moved to the position closest to the motor 3, and then cleaning is performed in the same manner as described above. In other words, cleaning with the wiper material 53 is performed only from the inner circumference to the outer circumference of the information recording surface of the optical disc 1. Here, while the drive section 6 is returned to the motor 3 side, the reel 51 is rotated by a certain amount in the winding section 63.

Thereby, the wiper material 53 can be advanced to an unused area for the next cleaning operation.

In this embodiment, the wiper material 53 is wound up at a slow speed during cleaning with the wiper material 53, but instead of this, during cleaning, the wiper material 53 is not wound up and a certain amount is wound before or after cleaning. It may also be configured to be wound up.

Further, in this embodiment, the width of the wiper material 62 is narrower than the radius of the information recording surface of the optical disc 1, but it is also possible to have the same width or a slightly wider width. Naturally, a configuration for moving the drive unit 6 in the radial direction of the optical disk 1 is not required.

Furthermore, in this embodiment, since the reel 5L52 and the wiper material 53 are stored and equipped in the cassette 5,
Replacing the cassette 5 after use is very easy; for example, attach a leader tape to the tip of the wiper material of a new cassette, and after loading the cassette, wind up the leader tape to expose the wiper material. This prevents grease or dust from adhering to the wiper material even if it comes into contact with the wiper material during replacement.

[Effects of the Invention] As described above, the disk cleaner according to the present invention has the following advantages:
Since cleaning is performed using a windable tape-shaped cleaning member, it is possible to transfer the cleaning member from a used area to an unused area without any human hands touching the area. This prevents grease or dust from adhering to the cleaning member from human hands, eliminates problems caused by continuous cleaning with removed dust accumulated, and ensures that the information recording surface of the disc is clean. The present invention has excellent effects such as being able to perform cleaning.
