Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a disk cleaning device for cleaning the surface of a disk such as an optical disk.

Conventional technology In recent years, the commercialization of video discs and compact discs,
Furthermore, the development of data disks and the future potential of the disk industry are highly anticipated.

In particular, optical discs are becoming mainstream in the disc industry due to their non-contact nature and long lifespan, but on the other hand, the effects of dust, dirt, etc. adhering to the disc surface (dropout data loss) have become a problem that cannot be ignored. There is. To deal with this problem, many devices have been developed that operate optical discs by inserting them into cartridges, but these devices cannot completely deal with dust and dirt, so there is a need for a disc cleaning device. ing.

Several types of cleaning devices for compact discs are already commercially available as this type of cleaning device. FIG. 4 shows a schematic diagram of an example. The user opens the holder 3, which is rotatably supported on the main body 1 at a fulcrum 2, and inserts the compact disc 10 into the main body 1. A knob 5 to which a cleaning pad (not shown) is attached inside through a slit 4 is provided on the lid 3 so as to be slidable in the direction of the arrow. The compact disc 6 is cleaned by the cleaning pad by sliding it in the direction of the arrow.

Further, this device is provided with a mechanism that rotates the compact disk 6 in response to the sliding movement of the knob 5, and the cleaning operation is completed by one rotation of the compact disk 6. There is.

Problems to be Solved by the Invention However, in the above configuration, since the user performs cleaning by sliding the knob, the user may slide the knob while pressing with excessive force. In this case, there is a problem of scratching the surface of the disc. Especially for data discs etc.
Scratches can become fatal defects and pose a major problem.

In addition, because the pad is slid many times with the wiped dust and dirt still attached to the pad, there is a problem that the wiped dust and dirt may adhere to other areas or scratch the disc surface. It also had the following.

The present invention aims to provide a disk cleaning device that solves these drawbacks.

Means for Solving the Problems In order to solve the above problems, in the present invention, the cleaning pad is configured to contact the disk surface with a certain pressure (for example, 1oy/Cd), and the cleaning pad The structure is such that a brush is provided to clean the cleaning pad every time the operation is performed.

With this configuration, the disk is always cleaned with a constant pressure and also with a cleaning pad that is free of dust, dirt, etc., making it possible to provide a highly reliable disk cleaning device that does not cause scratches. It is something.

Embodiments Below, embodiments according to the present invention will be described with reference to the drawings.

FIG. 1 is a schematic configuration diagram of an embodiment of a disk cleaning device according to the present invention, and FIG. 2 is a configuration diagram of a cleaning pad portion for cleaning IJ-5. For example, a bonded cap 12 is slidably held by a guide pin 14 and a bearing 17 fixed to an arm 16 via a spring 16. Spring 1
5 is set so that a predetermined pressure (for example, 1 ofj/d) is applied when the pad 11 is in contact with the disk 40.

The arm 16 is supported by a pin 19 supported by the substrate 34.
It is rotatably held via the boss 18, and the spring 2
o is biased in the direction of arrow W. Therefore, the cleaning pad section 10 is configured such that the cap 12 is pressed against the side surface of the eccentric cam 21 by the biasing force of the arm 16, and the flange 13 is brought into contact with the cam surface 21a.
It is held in a defined position against a spring 15. The eccentric cam 21 has a brush 2 at a position corresponding to the cam surface 21a.
3, a worm wheel 24 is integrally constructed in a portion close to the substrate 34, and a pin 22 supported by the substrate 34 is integrated with the worm wheel 24.
It is rotatably held by.

6 - A turntable on which a 2514 disk 4o is placed, has a center boss 26 and a spur gear 27, and is rotatably supported by a base plate 34. A partially toothed gear 29 that is integral with the spur gear 2 is meshed with a worm wheel 28 that is rotatably held by a pin 3o supported by a base plate 34. The worm wheels 24 and 28 are configured to mesh with worms 31 and 32 which are rotated by a shaft 33 connected to a motor 35.

FIGS. 3(a) to 3) are schematic side views of the present disk cleaning device, and the operation thereof will be described below with reference to FIGS. 1 and 2.

FIG. 3(a) shows the state before the cleaning pad portion 1o contacts the disk 40 and starts the cleaning operation, in which the flange 13 is pushed down by the cam surface 21a, resisting the spring 15. The cleaning pad portion 1o is located at the lowest position. When the eccentric cam 21 rotates in the direction of the arrow 1 from this state, the flange surface 13 rises along the cam surface 21&, and finally the engagement with the cam surface 21a is released, and the pad 11 of the cleaning pad portion 1o 40, resulting in the state shown in FIG. 3 (b). In this state, the cleaning pad section 10 is applied with a predetermined pressure (for example, 1o 9
/ca) is in contact with the disk 40.

When the eccentric cam 21 further rotates in one direction, the cleaning pad portion moves toward the outer circumference of the disk 4o as the eccentric cam 21 moves while remaining in contact with the disk 4o with a predetermined pressure, until it reaches the outermost circumference of the disk 40. While performing the cleaning operation, the state shown in FIG. 3(0) is reached. Furthermore, eccentric cam 2
1 rotates in one direction, the flange surface 13 is rotated to the cam surface 21.
&, the cleaning pad part 10 separates from the disk 4o and reaches the lowest position in FIG.
It will be in state 9. At this time, the brush 23 provided integrally with the eccentric cam 21 moves to the pad 1 of the cleaning pad section 10.
The brush 23 cleans the disk 40 by passing over the pad 11 , and the dust and dirt attached to the pad 11 are removed by the brush 23 . When the eccentric cam 21 further rotates in the X direction, it returns to the state shown in FIG. 1(a).

In this way, a series of operations are repeated by rotating the eccentric cam 21 in one direction. This eccentric cam 21
The rotation operation is performed by the motor 36, and during the transition from the state shown in FIG. 3(C) to FIG. °) Rotate and always have a new part to clean. Therefore, the cleaning operation of the disk 4o is completed by rotating the disk 4o, for example, 36 times. In this mechanism, the position of the cleaning pad portion 1o is defined by the side surface of the eccentric cam 21 and the cam surface 21a,
It is designed so that only the cleaning pad part 1o can be easily replaced once it is disengaged from the cleaning pad part 1o. In the explanation of this embodiment, a configuration for cleaning a single disk has been shown, but it goes without saying that the present invention can also be applied to disks containing cartridges, which have been developed in large numbers in recent years.

Effects of the Invention By using the disk cleaning device according to the present invention as described above, the following effects can be obtained.

■ Discs are always cleaned with appropriate pressure, so there is no need to worry about scratches.

■ Since the cleaning pad is constantly cleaned with a brush, there is no need to clean the pad with dust or dirt, and the dust or dirt does not stick to the disc again, and there is no damage caused by this.

(2) Since the disk is rotated by a predetermined angle while the cleaning pad is not in contact with the disk, the cleaning operation can always be performed only by moving the disk in the radial direction.

■ Cleaning pads are very easy to replace.

It has such great effects that it is possible to perform extremely reliable disk cleaning.
