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 and the filing date on June 8, 1998, entitled "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, in which a disc tray is used to load and unload a disc-shaped recording medium (such as an optical disc, etc.). Background technique [0003] In the earlier application filed by the assignee of this application, the above-mentioned type of disc drive device has been proposed. Figure 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 placed in the recess 3 horizontally. Then, when the tray front panel 2B of the disc tray 2 is gently pushed in the direction of arrow a, a loading switch (not show...
