Abstract

A thin display apparatus equipped with a video display panel controls rise in temperature of a disk drive by heat-transfer from high temperature internals of the apparatus. A thermal insulating recess is formed in a face of a rear side casing which faces a disk drive unit, and a surface of the disk drive unit mounted on the rear side casing seals the thermal insulating recess. An area of the thermal insulating recess sealed by the disk drive unit becomes a thermal insulating layer between the rear side casing and the disk drive unit, and the thermal insulating layer interrupts thermal transfer from the high temperature internals of the apparatus to the disk drive unit.

Claims

1. A display apparatus, comprising:

a display panel;

a casing being provided on a rear side of the display panel and constituting an exterior of the display apparatus;

a disk drive unit mounted outside the casing, and a covering member in which the disk device unit is mounted, wherein a first recess is formed in a part of the casing opposite to the disk drive unit, and the covering member is mounted on the casing, so that the disk drive unit seals the first recess;

wherein a second recess is formed in the casing to fit with the covering member, the first recess is formed inside the second recess, and the covering member is fitted in the second recess, so that the disk drive unit contacts the second recess to seal the first recess.

2. The display apparatus according to claim 1, wherein the first recess serves to thermal insulation.

3. The display apparatus according to claim 1, wherein the disk drive unit mounted on the casing seals the first recess.

4. The display apparatus according to claim 3, wherein the sealed first recess is filled with air.

5. The display apparatus according to claim 1, wherein the second recess is shallower than the first recess.

6. The display apparatus according to claim 1, wherein the first recess has an area which is approximately three fourth of an area where the disk drive unit faces the casing.
