Among such information filing devices, optical disk devices, which use optical disks as information storage media to record necessary information, and also search and reproduce the recorded information, are notable for their significantly large recording capacity. It has been widely put into practical use.

Information is recorded using this optical disk device by optically reading and scanning the surface of the document to be recorded with a laser beam, converting the black and white information on the document surface into an electrical signal (analog signal), and converting this analog signal into an electrical signal (analog signal). After FM modulating the recording signal, the laser beam generated by the laser light source is 0N-OF modulated using the recording signal, and the recording layer of the optical disk rotating at a constant speed is irradiated with this. This is done by changing the optical properties of the site.

To reproduce the recorded document, an optical disk is rotated at a constant speed, a beam of constant intensity is irradiated along the track on the optical disk, and the modulation state of the reflected light from the recorded part is converted into an electrical signal. This is done by reading out the information.

First, the configuration of a conventional optical disk device having the above-mentioned functions will be explained with reference to FIGS. 4 to 7.

In FIG. 4, 2 is a cassette case (cartridge) containing a disc-shaped optical disc 1 as an information storage medium, and this can be separated into 2o and 21 in order to expose the optical disc 1 within 6 degrees of the main body of the device. It is composed of

(Problems to be Solved by the Invention) However, in the optical disc device described above, the optical disc 1 is always stored in the cassette case 2, and when it is taken into the device main body 60 and placed on the turntable 9. Since the surface of the disc is exposed, for example, if foreign matter such as dust adheres to the surface during recording, playback, or storage, disassemble the cassette case 2, remove the optical disc 1, and clean it with a cloth or cotton swab. It was necessary to perform a tedious cleaning process of wiping off foreign objects.

However, disassembling the cassette case 2 that houses the optical disc 1 not only requires specialized knowledge;
Even if the foreign matter is actually wiped with a cloth, it is difficult to completely remove foreign matter from the surface of the optical disc, and there is a great possibility that the surface of the optical disc 1 will be damaged.

Therefore, there is a problem in that the optical disc 1 has to be used with foreign matter still attached to the surface of the optical disc 1, that is, with the recording/reproducing performance being inhibited.

SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems, it is an object of the present invention to provide an information processing apparatus equipped with a cleaning means for removing foreign matter such as dust attached to the lower surface of an information storage medium. be. .

[Structure of the invention]

(Means for Solving the Problems) That is, the information processing apparatus of the present invention includes a support means for horizontally supporting a rotatable information storage medium, and a lower surface of the information storage medium supported by the support means. The apparatus is characterized by comprising a suction means for removing dust attached to the apparatus.

(Function of the Invention) The optical disk device of the present invention includes a support means for horizontally supporting a rotatable information storage medium, and a support means for removing dust attached to the lower surface of the information storage medium supported by the support means. Since it is constructed with a suction means for removing, it is possible to simultaneously clean foreign matter such as dust adhering to the lower surface of the information storage medium during recording and playback of the information storage medium, which was difficult to remove in the past. .

(Description of Embodiments) Hereinafter, embodiments of the information processing apparatus of the present invention will be described in detail using the drawings.

In Fig. 1, numeral 1 is a disc-shaped optical disc as an information recording medium, which is usually housed in a cassette case (cartridge) 2 and locked to prevent foreign matter from adhering to it. sealed in condition.

Reference numeral 3 denotes a main body case that covers the mechanical section of the optical disk device, and a part thereof is provided with an insertion/removal opening 4 for inserting and removing the cassette case 2, and a shutter 5. The shutter 5 is closed on the outside when the cassette case 2 is inserted or ejected, and prevents foreign matter such as dust from entering the main body of the apparatus.

Reference numeral 6 denotes a base on which the mechanical part of the optical disk device is mounted, and is fixed to the main body case 3 via rubber gaskets 7 such as rubber feet in order to enhance the vibration-proofing effect.

9 is a turntable, and optical disc 1 is on it.

At the same time, the clamper 11 is used to clamp the disc and rotate it. Note that while the optical disc 1 is rotating, the cassette case 2 is supported by the support 10.

The optical head 15 for recording and reproducing data on and from the optical disc 1 is adapted to slide on the exposed bottom or top surface of the optical disc 1 in the radial direction of the optical disc 1, as shown in FIG.

The illustrated optical disk device actually includes the above-described case transport/opening/closing unit, unit displacement means, optical disk drive device, optical head moving device, etc., but these are omitted in the drawing.

As shown in the figure, the optical disc device of the present invention described above has a suction means (
This embodiment is characterized by the provision of a suction nozzle 12).

That is, the suction nozzle 12 is connected to a fan 13 provided on the side surface of the main body case 3 via a suction pipe 14, and its tip opening faces the exposed surface of the optical disc 1.

The tip installation device of this suction nozzle 12 only needs to face the exposed surface of the optical disk 1, for example, the optical head 1
Any position such as the vicinity of 5, the opposite side of the optical head 15, or the upper or lower surface of the optical disc 1 can be selected.

To actually operate the optical disk device of the present invention described above, first, the cassette case 2 containing the optical disk 1 is inserted through the insertion/ejection opening 4 of the main case 3.

Then, the cassette case 2 is taken into the main body of the apparatus by the action of the feed roller 98, etc., and the lock is released, and the central part or the radius part opens at an appropriate angle, and the optical disc 1 with a partially exposed surface is placed on the turntable. The cassette case 2 is placed on the support column 10.

In this state, the upper surface of the central portion of the optical disc 1 is clamped by the clamper 11, and the optical disc 1 is rotated by driving the motor 8.

Next, the optical head 15 slides onto the exposed surface of the rotating optical disc 1, thereby performing recording and reproduction.

When the presence of foreign matter is detected on the surface of the optical disc 1, a fan drive motor (not shown) is rotated,
When the fan 13 is activated, the suction nozzle 12 suctions the exposed surface of the optical disc 1, and the foreign matter is removed by the fan 1.
It is removed in three directions and efficient leaning is achieved.

Note that it is of course possible to keep the fan 13 constantly rotating during recording/playback of the optical disc 1, and to continue recording/playback and cleaning operations at the same time.

In the embodiment described above, it is particularly desirable that the suction nozzle 12 be provided facing the bottom surface of the optical disk 1. With this configuration, the bottom surface of the horizontally rotating optical disk 1 is sucked, so that the gravity of the foreign object itself is absorbed. The removal effect can also be enhanced by using the same method, and even more efficient lean can be achieved.

Further, as shown in FIG. 2, it is preferable that the tip opening of the suction nozzle 12 has an elongated shape whose suction width is equivalent to the radial width of the optical disc 1. The entire surface and circumference of the optical disc 1 is cleaned, making it possible to completely remove attached foreign matter.

Furthermore, as shown in FIG. 3, the distance between the tip of the suction nozzle 12 and the surface of the optical disk 1 is equal to the surface runout distance of the optical disk 1! This completely eliminates the risk of the suction nozzle 12 damaging or abrading the surface of the optical disc 1 when the optical disc 1 is deflected, thereby increasing the reliability of the cleaning effect. improves.

In this way, foreign matter sucked by the suction nozzle 12 is adsorbed by the filter 16, and foreign matter such as dust from the outside is also adsorbed by the filter 16, and there is no possibility of it entering into the main body of the device, which improves the cleaning effect. In addition to this, it is possible to obtain the effect of protecting the optical disc 1 and the main body of the apparatus.

〔Effect of the invention〕

As described above in detail with reference to the embodiments, the optical disk device of the present invention includes a support means for horizontally supporting a rotatable information storage medium, and a lower side of the information storage medium supported by the support means. Since it is composed of a suction means that removes dust attached to the surface, foreign matter such as dust attached to the lower surface of the information storage medium, which was difficult to remove in the past, can be removed.
It is possible to simultaneously clean the information storage medium during recording and reproduction.

Therefore, the present invention can greatly improve the added value of an information processing device, and can also improve the durability of an information storage medium.
