Abstract

Disclosed is a disk drive device which can avoid as far as possible dirt and dust from being sucked into a disk device body together with open air. An intake port is formed in a front panel of a disk device body along a lower edge of a tray entrance / exit opening. An intake passage formed between printed boards in the disk device body and a lower cover thereof is communicated at a front end thereof with the intake port. A discharge port opened to the outside of the lower cover is formed in the intake passage.

Description

[0001] This application is a divisional application of the Chinese patent application with the application number 03141279.3, the filing date being June 8, 1998, and the title "disk drive device". technical field [0002] The present invention relates to the technical field of disc drive devices, preferably a disc drive device for an optical disc drive device, wherein a disc tray is used to load and eject a disc-shaped recording medium (such as an optical disc, etc.). Background technique [0003] A disc drive of the above type has been proposed in an earlier application filed by the assignee of the present application, and reference will be made below to the attached Figures 1 to 14 Explain it. Such as figure 1 As shown, a recess 3 is formed on the upper surface of the tray body 2A of the disc tray 2, and an optical disc 1 as a disc-shaped recording medium is horizontally placed in a recess 3. As shown in FIG. Then, when the tray front panel 2B of the disc tray 2 is push...
