Description

BACKGROUND OF THE INVENTION 1. 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.

2. Description of the Related Art In recent years, the commercialization of video discs and compact discs, and further the development of data discs, the disc industry has great promise for its potential.

In particular, optical discs are becoming the mainstream in the disc industry from the viewpoint of non-contact and long life, but on the other hand, the influence of dust and dust adhering to the disc surface (dropout data loss) has become a problem that cannot be ignored.

In order to deal with this problem, a number of devices have been developed that put an optical disk in a cartridge and operate it.
Since it is not possible to completely deal with dust and dirt, there is a demand for a disk cleaning device.

As this type of cleaning device, several types of cleaning devices for compact discs have already been marketed. FIG. 4 shows a schematic diagram of an example thereof. The user opens the lid 3 which is rotatably supported by the fulcrum 2 on the main body 1 and opens the compact disc.
Put 10 in the body 1. The lid 3 has a slit 4
A knob 5 having a cleaning pad (not shown) attached inside is provided slidably in the direction of the arrow. After closing the lid 3, the knob 5 is slid in the direction of the arrow. The compact disc 6 is cleaned by the cleaning pad. Also, in this device,
A mechanism for rotating the compact disc 6 in response to the sliding movement of the knob 5 is provided, and the cleaning operation is completed by rotating the compact disc 6 once.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above-mentioned configuration, since the user has a structure in which cleaning is performed by sliding the knob, the user slides the knob while pressing it with an excessive force. In this case, there is a problem of scratching the surface of the disc. Especially for data discs,
A flaw is a serious problem because it can be a fatal defect.

Also, since wiped dust, dust, etc. are repeatedly slid on the pad, there is a problem that wiped dust, dust, etc. will adhere to other places, and the disc surface will be scratched by dust, dust, etc. Was also possessed.

The present invention is intended to provide a disk cleaning device that solves such 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 at a certain constant pressure (for example, 10 g / cm ² ), and A brush is provided for cleaning the cleaning pad each time the cleaning operation is performed once.

With this configuration, the disc is always cleaned at a constant pressure, and at the same time, the disc is always cleaned with a cleaning pad free of dust, dust, etc., so that a highly reliable disc cleaning device free from scratches or the like can be provided. It is a thing.

Examples Hereinafter, examples 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. The cleaning pad section 10 has a pad 11
For example, the cap 12 with the adhesive is spring-loaded by the guide pin 14.
A bearing 17 fixed to an arm 16 is slidably held via 15. The spring 15 is set to have a predetermined pressure (for example, 10 g / cm ² ) when the pad 11 is in contact with the disk 40.

The arm 16 is attached to the boss 18 by the pin 19 supported by the substrate 34.
It is rotatably held via and is biased by the spring 20 in the direction of arrow w. Therefore, the cleaning pad portion 10 is positioned against the spring 15 by the cap 12 being pressed against the side surface of the eccentric cam 21 by the urging force of the arm 16 and the flange 13 contacting the cam surface 21a. Is held. The eccentric cam 21 has a brush 23 integrally formed at a position corresponding to the cam surface 21a, and a worm wheel 24 integrally formed in a portion near the substrate 34, and is rotatably held by a pin 22 supported by the substrate 34. Has been done.

Reference numeral 25 denotes a turntable on which the disc 40 is placed, which has a center boss 26 and a spur gear 27, and is rotatably supported by the substrate 34. The spur gear 27 meshes with a toothless gear 29 integral with a worm wheel 28 rotatably held by a pin 30 supported by a substrate 34. Worm wheels 24 and 28 have
The worms 31, 32 rotated by a shaft 33 coupled to the motor 35 are in mesh with each other.

3A to 3D are schematic side views of the present disk cleaning apparatus, and the operation thereof will be described below with reference to FIGS.

FIG. 3A shows a state before the cleaning pad portion 10 comes into contact with the disc 40 and starts the cleaning operation. The cleaning pad portion 10 is pushed down by the flange 13 or the cam surface 21a, so that the cleaning is performed against the spring 15. Pad 10 is in the lowest position. When the eccentric cam 21 rotates in the direction of arrow x from this state, the flange surface 13 rises along the cam surface 21a, and finally the engagement with the cam surface 21a is released, so that the pad 11 of the cleaning pad portion 10 becomes a disk. The state shown in Fig. 3B is in contact with 40. In this state, the cleaning pad portion 10 is in contact with the disc 40 by the spring 15 at a predetermined pressure (for example, 10 g / cm ² ). When the eccentric cam 21 further rotates in the x direction, the cleaning pad portion moves in the outer peripheral direction of the disk 40 as the eccentric cam 21 is displaced while being in contact with the disk 40 at a predetermined pressure.
As shown in FIG. 3B, the cleaning operation is performed up to the outermost circumference. When the eccentric cam 21 further rotates in the x direction,
The flange surface 13 is pushed down by the cam surface 21a, and the cleaning pad portion 10 is separated from the disk 40, and the state shown in FIG. At this time, the eccentric cam 21
The brush 23 provided integrally with the cleaning pad 10
When the disk 40 is cleaned by this operation that passes over the pad 11, the brush 23 removes the dust and dust adhering to the pad 11. When the eccentric cam 21 further rotates in the x direction, the state shown in FIG.

In this way, the eccentric cam 21 rotates in the x direction to repeat a series of operations. The rotating operation of the eccentric cam 21 is performed by the motor 35, and the turntable 25 and the disk 40 are operated at a predetermined angle (for example, 1 / Rotate 36 °) and always clean new parts. Therefore, the cleaning operation of the disk 40 is completed by rotating the disk 40, for example, 36 times. In this mechanism, the cleaning pad unit 10 is
The position is defined by the side surface of the eccentric cam 21 and the cam surface 21a, and it is considered that only the cleaning pad portion 10 can be easily replaced by releasing this engagement. Further, in the description of the present embodiment, the configuration in which the single disk is cleaned has been shown, but it goes without saying that the present invention can also be applied to many cartridge-containing disks that have been developed recently.

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

The discs are always cleaned with the proper pressure and there is no risk of scratches.

Since the cleaning pad is always cleaned with a brush, cleaning is not performed on the pad with dust and dirt, dust and dirt do not reattach to the disk, and there is no damage due to this.

Since the disc is rotated by a predetermined angle when the cleaning pad does not contact the disc, the cleaning operation can always be performed only in the radial direction of the disc.

The cleaning pad is very easy to replace.

With such a large effect, it is possible to perform a highly reliable disk cleaning.
