Patent number: 8051440Abstract: According to one aspect, an optical read/write device for reading and/or writing an optical disc includes a base, optical pickup head, and a driving mechanism for slidably driving the optical pickup head. The driving mechanism includes a worm gear, a motor for rotating the worm gear, and a rack disposed between the worm gear and the optical pickup head for transferring motion from the worm gear to the optical pickup head. The rack includes a fastening portion for fixing the rack to the optical pickup head, a mesh portion for engaging with the worm gear, a restricting portion connected to the mesh portion for being blocked by the gear seat when the mesh portion is pressed by the worm gear to prevent the mesh portion from disengaging from the worm gear, and a connecting portion for connecting the fastening portion with the restricting portion.Type: GrantFiled: March 13, 2008Date of Patent: November 1, 2011Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Hung-Ming Lin, Xi-Ping Dai

Patent number: 7409696Abstract: An opening actuator for a video disc player includes a clasp arm with a clasp hole at a distal end thereof, a press button, an elastic component for repositioning the press button and a cover. The press button includes a stop portion for limiting a stroke of the press button, a clasp portion, and at least one guide portion. The cover includes a positioning member and at least one guide member receiving the at least one guide portion. The clasp portion of the press button engages in the clasp hole of the clasp arm for holding the top lid on the cover, and the press button can actuate the clasp portion thereof to exit the clasp hole for releasing the top lid from the cover. Because the press button is located in a side of the cover of the video disc player, there is little risk of the press button being accidentally actuated.Type: GrantFiled: December 21, 2004Date of Patent: August 5, 2008Assignees: Hong Fu Jin Precision Industry (Shenzhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventor: Xi-Ping Dai

Publication number: 20050240949Abstract: 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.Type: ApplicationFiled: September 30, 2004Publication date: October 27, 2005Applicant: HON HAI Precision Industry CO., LTD.Inventors: Jin-Feng Liu, Jun-Feng Mu, Xi-Ping Dai
