DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disk device,
In particular, the present invention relates to an optical disc device incorporating an air filter for increasing the air cleanliness of the optical disc device.

[0002]

2. Description of the Related Art The structure of a conventional air filter unit of this type of optical disk device is shown in FIG. 5, and the structure of an optical disk device equipped with this air filter unit is shown in FIG. 5A is a front view of the air filter unit 1, showing an optical disk device mounting surface, FIG. 5B shows a glass fiber paper filter 2, and FIG. 5C is a filter case 4 having an intake hole 3. Is shown.

In a conventional air filter unit 1 for an optical disk device, a glass fiber paper 2 is used as a material of an air filter by being woven in a comb shape, which is enclosed in a plastic case 4 having an intake hole 3 to form a unit. It was done.

This air filter unit 1 is shown in FIG.
As shown in (A) to (C), when air for cooling the optical disc drive 6 and the optical disc medium 7 in the optical disc device housing 5 is sucked from the outside of the device by a cooling fan 8 mounted in the device, It is attached to the air intake hole 9 in order to remove suspended dust in the air. The flow of the cooling air inside the optical disk drive 6 is generally a flow of intake from the rear opening 10 and exhaust from the front medium insertion hole 11.

Further, since it is difficult to mount the air filter unit 1 on the front surface of the apparatus with a small mounting space,
As shown in FIG. 6, it is generally mounted on the back surface of the device.

As another conventional air filter structure of this type, as shown in Japanese Patent Application Laid-Open No. 2-71487, a filter is provided so as to cover the entire casing frame of an optical disk device. There is something.

Another conventional air filter structure is disclosed in Japanese Utility Model Laid-Open No. 3-32800. In this example, the inside of the case of the optical disk device is used as an air circulation flow path, and a small breathing hole is provided in a part thereof, and the small breathing hole is covered with an air filter.

[0008]

In the structure shown in FIGS. 5 and 6, the optical disk drive 6 is used for forced cooling in the device.
In addition, the air filter unit 1 is provided in the intake hole 9 formed in the rear surface of the device so that the optical disk medium 7 is not exposed to dust in the air, and the dust is removed before flowing into the cooling air device. In order to do so, it is necessary to mount the air filter unit 1 on the perforated surface of the intake hole 9 outside the device.

Therefore, the external dimensions of the device are increased, the workability of replacing the air filter unit in the rear part of the device is deteriorated, and in the optical disk device with the built-in host computer main body, the high temperature air inside the computer is used for cooling, so the cooling efficiency There is a problem such as bad.

Further, in the structure disclosed in Japanese Patent Application Laid-Open No. 2-71487, the air filter covers the entire housing frame, so that the workability of replacing the air filter is significantly deteriorated. , The entire surface of the device is an intake hole,
Since it becomes an exhaust hole, there is a problem that the flow of gas in the device becomes indefinite and cooling efficiency also decreases.

Further, in the structure of Japanese Utility Model Laid-Open No. 3-32800, since the breathing holes are small, the filter area covering them is also small, so that the dust collection efficiency and life of the filter are significantly deteriorated. There is.

An object of the present invention is to provide an optical disk device having an air filter which is small in size and has good cooling efficiency and good maintenance workability.

Another object of the present invention is to provide an optical disk device having an air filter which improves dust collection efficiency and life.

[0014]

An optical disk device according to the present invention is an optical disk insertion hole provided in the front surface of a main body case of the optical disk device, an air suction hole provided in the front surface of the main body case, and an air suction hole. It is characterized by including a bag-shaped air filter having an opening fitted in the hole, and a holding frame provided with the air filter and holding the bag-shaped air filter.

[0015]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an optical disk device according to an embodiment of the present invention, and the same parts as those in FIGS. FIG.
(A) is a side view of the apparatus, (B) is a front view, and (C) is a top view. 2 shows the structure of the air filter unit used in the embodiment of the present invention, (A) is a side view, (B) is a bottom view, (C) is a front view, and (D) is A of (B). FIG.

An optical disk device housing (case) 5 to which the air filter unit 1 can be mounted is provided with a cooling air intake hole 9 in the front surface of the device (the surface where the disk insertion hole 11 is formed). The air filter unit 1 is installed,
The structure used.

The cooling air in the optical disk device housing 5 is
Immediately after being sucked by the cooling fan 8 from the air inlet 9 on the front side of the apparatus, dust is removed at the same time when it passes through the air filter unit 1, then flows inside the optical disk drive 6 and the vicinity of the optical disk medium 7, and is inserted into the medium insertion hole 11 on the front side of the apparatus. It forms a series of flow paths that are more discharged.

The air filter unit 1 is composed of a bag-shaped charged fiber layer filter 12, a device fixing cap 13 and a filter shape holding frame 14. The charging filter 12 is crowned, and the cap 13 and the filter 12 are heat-welded and assembled at the overlapping portion.

Next, the functions of this embodiment will be described with reference to FIGS.
This will be described with reference to FIG. The charging filter 12, which is one of the configurations of the air filter unit 1, needs to have a large air filtration area in order to improve the dust collection efficiency and the service life, which are the performance of the filter itself. In the filter unit 1, a mat-shaped filter material is heat-welded to have a bag shape that is long in the mounting direction.

The device fixing cap 13 is formed by using an elastic resin material, and enhances the fitting force when it is mounted in the air intake hole 9 on the front surface of the optical disk device, and has a confidentiality for preventing the outside air from entering. I am raising.

The filter shape holding frame 14 secures a space inside the bag of the charging filter 12, thereby preventing an increase in pressure loss and a decrease in dust collecting efficiency having an element that deteriorates the cooling efficiency of the apparatus, and also the mold collapses. It is intended to improve the workability deterioration when attaching and detaching the air filter unit 1.

4 (A) to 4 (C) are a side view, a front view and a top view showing the structure of another embodiment of the present invention, and the same portions as those in FIG. 1 are designated by the same reference numerals. In this example, intake holes 9 are provided at both ends of the disk insertion hole 11 on the front surface of the apparatus housing 5, and the air filter units 1 are attached to these, respectively.

[0024]

As described above, according to the air filter unit for an optical disk device of the present invention, it can be mounted if there is a space for providing a slight opening on the front surface of the optical disk device. As a result, the air filter unit can be mounted inside the device, without increasing the external shape of the device and hindering workability when replacing the air filter unit, and sucking cooling air in the optical disk device with a built-in host computer body. Also, since it can be performed from outside the device, it is possible to prevent a decrease in cooling efficiency.

Further, since the air filter has a vertically long bag shape, even if the area of the intake hole is small, the air filtering area is large, so that the dust collection efficiency and the life are improved. is there.
