  • Patent number: 7640558
    Abstract: Increases in the data transfer rates of optical disc drives have resulted in problems such as increases in optical disc vibrations due to higher rotation speeds or increases in heat generation due to increases in the output of motors for rotating the optical discs and in the output of laser diodes. To solve such problems, an optical pickup is provided with an air duct therein, and a space that is formed between the optical disc and a top case of a casing and that has negative pressure during rotation of the optical disc is connected to the air duct in the optical pickup via a tube, at least part of the tube being deformable. The optical pickup is cooled by the air flow through the air duct induced by pressure difference.

  • Patent number: 7614062
    Abstract: This invention provides an optical disk device in which heat generated from an optical head and circuit board is dissipated without introduction of outside air or use of a fan. A through portion is provided in part of the mechanical block or outside of the portion on which a tray is projected for carrying a disk for reproduction or write, such that it extends from a disk side portion with respect to the tray to a portion opposing the disk with respect to the tray, in order to introduce air flow generated by disk rotation to an optical head and circuit board and dissipate heat generated at the time of recording or reproduction.

  • Publication number: 20090174626
    Abstract: To provide a reliable high brightness and definition image display by inhibiting a possible increase in fan noise and promoting cooling of an upper, hot portion of a display panel module, various boards, and image processing electronic components, an image display includes a flat display panel module, a display surface side cover on a display surface side of the display panel module, a non display surface side cover on a non display surface side of the display panel module, a display driving board, a power supply board, and a cooling fan, wherein a case of the cooling fan is larger than a distance between the display panel module and the non display surface side cover in an area where the cooling fan is installed, and a first end of the case of the cooling fan closer to the non display surface-side cover is positioned above a second end of the case closer to the display panel module.

  • Publication number: 20070079312
    Abstract: An optical disc drive, comprising: a housing; a tray for transferring an optical disc, having a disc mounting portion for mounting the optical disc thereon, and being movable into an inside and a front of the housing; a motor for rotationally driving said optical disc; an optical pickup, having one or more of laser diode(s) for generating a laser beam for conducting recording/reproducing of information onto/from the optical disc, and for irradiating the laser beam upon the optical disc; and a first penetrating hole, for letting the rotation device and the laser beam passing therethrough, being provided within the disc mounting portion and also in rear of said disc mounting portion, on the tray, wherein a second penetrating hole is further provided in rear of the disc mounting portion, in an upstream side of rotating direction of the optical disc than the first penetrating portion, and the second penetrating portion is larger in area than a total of area(s) obtained by projecting the laser diode(s) onto the op
