Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disk device having a magneto-optical disk reader for reading data from a magneto-optical disk.

[0002]

2. Description of the Related Art In a magneto-optical disk reader for reading data from an optical disk such as a CD or DVD, or a magnetic disk such as a hard disk or a floppy (registered trademark) disk, if dust or the like adheres to a data reading section or a disk surface, A data reading error may occur.

For this reason, in the magneto-optical disk reader, in order to surely read data from the magneto-optical disk, it is necessary to take measures against dust to prevent dust from entering from outside. Conventionally, such dustproof measures include:
By sealing the entire device including the magneto-optical disk reader, dust is prevented from entering the inside of the magneto-optical disk reader.

[0004]

However, in such a dustproof structure that seals the entire device, it is necessary to form a sealed structure by eliminating a gap in, for example, a housing or the like that houses the magneto-optical disk reader. Parts are required. In some cases, packing for closing the gap is required. For this reason, in the magneto-optical disk device having such a configuration, there is a problem in that components cannot be diverted from general equipment that has not been subjected to dust-proofing measures, resulting in a high cost.

SUMMARY OF THE INVENTION In view of the above, it is an object of the present invention to provide a magneto-optical disk drive having a magneto-optical disk reader, while ensuring the dust-proofness of the magneto-optical disk reader, and enabling parts to be diverted from general equipment. And

[0006]

In order to achieve the above object, according to the first aspect of the present invention, a magneto-optical device which is built in a housing (11) and reads electronic data recorded on a magneto-optical disk. It is characterized by comprising a disk reading section (10) and a dustproof member (14) that covers only the magneto-optical disk reading section (10) and prevents dust from entering the magneto-optical disk reading section (10).

As described above, in the magneto-optical disk drive,
Magneto-optical disk reader (1
By using only the dust-proof member (14) as a dust-proof structure, the dust-proof structure of the magneto-optical disk reader (10) can be ensured, and the same parts as those of general equipment can be used for the housing (11) and the like. become able to. This makes it possible to provide a magneto-optical disk device which is provided with dust-proofing measures at low cost.

[0008] The reference numerals in parentheses of the above means indicate the correspondence with specific means described in the embodiments described later.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a cross-sectional view of the optical disk device of the present embodiment. The optical disc device according to the present embodiment has C
The present invention is applicable to home devices such as D players and DVD players, peripheral devices such as personal computers, and on-vehicle devices such as car audio and navigation devices.

As shown in FIG. 1, the optical disk device includes a magneto-optical disk reader 10, a housing 11, a dustproof member 1,
4 etc. are provided as main components.

The magneto-optical disk reader 10 has a C
Electronic data recorded can be read from an external storage device (storage medium) such as an optical disk such as D, DVD, MO, and MD, or a magnetic disk such as a hard disk or a floppy disk. The magneto-optical disk reading device 10 includes an optical or magnetic data reading unit.

The magneto-optical disk reader 10 is provided with a disk insertion portion 10a for inserting or ejecting a magneto-optical disk. When a hard disk is used as the magneto-optical disk, the disk insertion part 10a becomes unnecessary.

A code member 12 is connected to the magneto-optical disk reader 10. Cord member 12
Are similar to cables or connectors for transmitting information or power.

The housing 11 is a box-shaped member that houses and fixes the magneto-optical disk reader 10. In the housing 11,
Since a large number of gaps (not shown) are formed, dust can enter the housing from outside. In the housing 11,
Disk insertion unit 10 of magneto-optical disk reader 10
An opening for inserting and removing the magneto-optical disk is provided at a position corresponding to a. The magneto-optical disk reader 10 is fixed to the housing 11 by a plurality of fixing members (for example, screws) 13.

The dustproof member 14 is provided inside the housing 11 so as to cover (enclose) only the magneto-optical disk reader 10. The dustproof member 14 is a resin film formed from a polymer material. This resin film is formed by biaxial stretching so as to withstand heat generation of the device. Further, the resin film is subjected to an antistatic treatment or an antistatic treatment in order to prevent the influence of the static electricity on the device.

The dustproof member 14 is fixed to the housing 11 by using a tape, a locking screw, or by being sandwiched between the housings 11. The dustproof member 14 is provided with an opening for inserting and removing a magneto-optical disk at a position corresponding to the disk insertion portion 10a of the magneto-optical disk reader 10 as in the case 11. That is, the dustproof member 14 is configured to completely cover the portion of the magneto-optical disk reader 10 other than the disk insertion portion 10a. Thereby, the magneto-optical disk reading device 10
Is sealed, and dust that has entered the housing 11 is
And the dustproof member 14 is provided with a plurality of minimum necessary through holes for allowing the cord member 12 and the fixing member 13 to pass therethrough. Since wind pressure is generated inside the dust member 14 due to rotation of the magneto-optical disk,
The amount of dust entering the dust member 14 does not affect the data reading of the magneto-optical disk reader 10.

The decorative plate 15 serving as an outer surface is provided with an opening through which a magneto-optical disk is taken in and out. The magneto-optical disk is taken in and out in the direction of arrow A in the figure. An openable / closable lid 16 is provided in the opening of the decorative plate 15, and the opening is closed except when the magneto-optical disk is inserted or ejected.

A housing 1 is provided between the decorative plate 15 and the housing 11.
A seal member (packing) 17 is provided so as to surround the opening 1. Thus, dust can be prevented from entering the space formed between the decorative plate 15 and the housing 11 from the outside, and dust can be prevented from entering the magneto-optical disk reader 10 from the opening of the housing 11. . The sealing member 17
Use a foam material or similar product that prevents the effects of deformation.

As described above, in the magneto-optical disk drive, the magneto-optical disk reader 1 that requires dust protection is described.
By setting only 0 to a dustproof structure by the dustproof member 14,
The same components as those of general equipment can be used for the housing 11 and the like while ensuring the dust-proof property of the magneto-optical disk reader 10. This makes it possible to provide a magneto-optical disk device which is provided with dust-proofing measures at low cost.
