Optical recording/reproducing apparatus with dust resistant vents
First Claim
1. An optical recording/reproducing apparatus, comprising:
- an upper cover, a lower cover, a traverse module;
a printed circuit board; and
at least one air vent located on at least one of the covers, comprising a fist grille arranged at an inner surface of the cover and a second grille arranged at an outer surface of the cover, wherein the traverse module and the printed circuit board are accommodated in a housing cooperatively defined by the upper cover and the lower cover, the first and second grilles are parallel to each other, and the second grille is configured to block entry into the housing of foreign matter that is not blocked by the first grille.

Abstract
An optical recording/reproducing apparatus includes an upper cover, a lower cover, and several vents. Each vent is arranged on the lower cover, and includes a first grille and a parallel second grille. The first and second grilles each include parallel louvers interleaved by parallel gaps. The first grille is arranged at an outer surface of the lower cover, while the second grille is arranged on an inner surface of the lower cover, with a clearance h separating the first and second grilles. Heat produced in the optical recording/reproducing apparatus is expelled out from the housing via the gaps of the second grille and the gaps of the first grille. However, external dust or contaminants that may enter the gaps of the first grille are blocked from entering the housing by the louvers of the second grille.
