Field of the Invention The present invention relates to a cover for a disk drive device, and more particularly to a disk drive device mounted on a device used in an environment frequently exposed to dust, such as a window information terminal for public institutions. For the best cover.

[0002]

2. Description of the Related Art A contact information terminal for a public institution is a device having an information collecting function via a network and an auto dial function for automatically making a call to an information provider by issuing a command from the terminal. For example, such a terminal device includes a flexible disk drive device (hereinafter, FDD) for operation and maintenance of the device, and a hard disk drive device.

[0003] This type of terminal device usually has an exhaust device for discharging heat generated by power consumption of the device to the outside of the housing. A fan is attached to the inner wall of the housing for exhaust, and the fan exhausts air by discharging wind to the outside of the housing or sucking outside air into the housing. As shown in FIG. 8, many conventional exhaust devices forcibly exhaust hot air in a housing by a fan 2.

[0004] A method of mounting an FDD in a terminal provided with this conventional negative pressure type exhaust device will be described with reference to FIGS. 8 and 9. In FIG. 8, the fan 82 is attached to the inside of the
Exhaust air inside. Arrow 10 represents the air flow caused by the negative pressure created by fan 2. The air sucked into the housing from the ventilation slit 9 is
The hot air accumulated in the upper part is taken away and pushed out from the fan 2.

FIG. 9 is a perspective view showing a state in which the terminal equipped with the above-described negative pressure exhaust system is equipped with the FDD 3 when viewed from a direction opposite to that in FIG. FDD3 is a housing 81
Is mounted on a U-shaped base 85 attached to the side surface of the. To isolate the FDD 3 from the air flow indicated by the arrow 10, a lid 84 covering the upper bottom surface, the back surface, and the left and right side surfaces is covered. The FDD 3 is fixed from the side surface of the lid 84 with a screw.

A notch 88 for passing the flat cable 7 is provided on the rear surface of the lid 84. The packing 86 is fitted into the cutout 88 while sandwiching the flat cable 7. Packing 86
Presses the flat bottom surface against the base 85 and fits the notches 88 formed in the upper and side portions to seal the rear surface of the FDD 3.

[0007] In the terminal 81 employing the conventional exhaust device of the negative pressure exhaust system, the FDD 3 is stored in the above-mentioned state, thereby preventing air from flowing through the opening 31 of the FDD 3.

[0008]

On the other hand, as an exhaust system, a fan is installed in the opposite direction (or rotated in the opposite direction), and air is taken in from the outside of the case to generate pressure in the case. There is an internal pressure exhaust system for performing exhaust. In this case, the problem of the inflow of air from the opening of the FDD as described above does not occur. However, conversely, since the air inside the housing is blown to the FDD by the fan, if the FDD is stored in the above-described state,
Dust easily accumulates in the FDD.

Conventionally, since the FDD is screwed from the side, distortion of the FDD occurs due to the tightening torque of the screw, which may cause a read error / write error of the FDD medium.

[0010] Accordingly, an object of the present invention is to provide a terminal employing an exhaust device of either a negative pressure type or an internal pressure type,
An object of the present invention is to provide a cover that protects a disk drive such as a DD from dust and that does not cause distortion in the disk drive.

[0011]
