Embodiment Construction

[0023] According to the present invention, the heat of the semiconductor element is efficiently transferred to one drawer side. Heat convection is included by the velocity of the wind near the disc, which is opposite the area near the drawer. The heat transferred to the above-mentioned drawer side is efficiently radiated to the atmosphere. Therefore, an increase in the internal temperature of the optical disc device is suppressed.

[0024] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In the corresponding drawings, the same reference numerals are assigned to the same positions, and repeated explanations are omitted.

[0025] figure 1 and figure 2 is an exploded perspective view of the main part of the optical disc device according to the embodiment of the present invention. figure 1 The optical disc device is shown when viewed obliquely from the rear side. figure 2 The optical disc device is shown whe...

Abstract

The optical disc device of the present invention has a PC main board carrying semiconductor components and connected to the rear side of the drawer to efficiently dissipate heat generated by the semiconductor components. The drawer is formed of a material with good thermal conductivity. A thermal conductor with good thermal conductivity is inserted between the IC to be dissipated and the drawer.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from prior Japanese Patent Application No. 2004-381991 filed on December 28, 2004 and Japanese Patent Application No. 2004-381992 filed on December 28, 2004; The entire contents of are hereby incorporated by reference. technical field [0003] The present invention relates to an optical disc device. More particularly, the present invention relates to an elongated optical disc device for carrying a notebook-sized personal computer having components in the form of a heat dissipation structure of a semiconductor element, such as for controlling the rotation of a disc motor motor driver IC (Integrated Circuit). Background technique [0004] Generally, a drive system IC, such as a motor driver IC for controlling the rotation of a disc motor mounted in an optical disc device, generates a large amount of heat. Therefore, a cooling mechanism is provided in the optical disc de...
