20080271062 | Optical disc apparatus - To prevent deformation of a chassis due to an impact force in an optical disc apparatus, there is provided a tray for inserting/ejecting an optical disc into/from an apparatus body, with the chassis connected thereto through vibration proof materials in plural portions in a surface opposite a disc placing surface. The tray has projecting portions projecting in a chassis direction in positions facing the chassis in peripheral portions of the plural connecting portions. The projecting portion is located at a position higher than a tray plane with which the vibration proof material comes into contact, and lower than the surface of a chassis facing the tray. When the vibration proof material is compressed and deformed due to the impact force, the projecting portion comes into contact with the chassis facing surface, to reduce the amount of deformation of the vibration proof material and thereby prevent deformation of the chassis. | 10-30-2008 |
20090222844 | Optical Disc Apparatus - There are provided a disk motor arranged on a chassis, an optical pickup that performs recording and reproducing of a signal from an information recorded surface of an optical disk, a pair of guide shafts arranged on the optical pickup to guide the optical pickup radially of the optical disk, adjustment screw that move at least one ends of the guide shafts in a direction substantially perpendicular to a surface of the chassis, a leaf spring arranged on a frame body to bias the one end of the guide shaft toward the surface of the chassis, and the leaf spring includes a support surface that supports the one end of the guide shaft, and a stopper portion projecting from the support surface to define a clearance between the support surface and the surface of the chassis. | 09-03-2009 |
20090262625 | OPTICAL DISK DEVICE - An optical disk device is provided to carry out a stable operation of a reflection-type photo sensor which detects a position of an optical pickup unit and to simplify an assembly process. The optical disk device includes: a chassis; an optical pickup unit which is disposed in the chassis and is moved in a radial direction of the mounted optical disk so as to carry out at least one of recording and reproducing of a signal on the information recording surface of the optical disk; a reflection-type photo sensor which is disposed in the chassis and includes a light-emitting unit and a light-receiving unit; a reflection unit which is disposed in the optical pickup unit and reflects light emitted from the light-emitting unit according to movement of the optical pickup unit so as to be incident on the light-receiving unit; and a black member which is disposed at a position facing the reflection-type photo sensor of the chassis, wherein the chassis is provided with a mold portion which is formed by mold forming, and wherein the black member is integrally formed with the mold portion. | 10-22-2009 |
20090265725 | OPTICAL DISC APPARATUS - An optical disc apparatus capable of being thinned and lightened while ensuring a mechanical strength and a stiffness, and also capable of restraining sticking of an FPC and reducing the sliding resistance of the FPC, comprises a frame, a motor arranged in the frame, for rotating an optical disc loaded in the optical disc apparatus, an optical pickup arranged in the frame so as to be movable in a radial direction of the optical disc, for carrying out at least one of recording and reproduction of signals onto and from a data recording surface of the loaded optical disc, an FPC arranged in the frame, for connecting between the optical pickup and a circuit board, and a unit cover for covering the frame on the mounting surface side of the optical disc, the unit cover having a first zone including an area made into contact with the FPC, and second zones projected toward the mounting surface side of the optical disc from the first zone and located on opposite sides of the first zone so as to interpose a part of the area made into contact with the FPC. | 10-22-2009 |
20090265726 | OPTICAL DISC DRIVE AND ELECTRONIC APPARATUS - An optical disc drive comprises: a disc tray | 10-22-2009 |
20100053806 | DISC DRIVE APPARATUS - A disc drive apparatus comprises: a spindle motor | 03-04-2010 |
20100223634 | OPTICAL DISC APPARATUS - An optical disc apparatus comprises the followings within housing thereof: an optical pickup, which is configured to conduct recording or reproducing of a disc, as an information recording medium; a rotation mechanism of said disc; a transfer mechanism, which is configured to move said optical pickup from an inner periphery of said disc up to an outer periphery thereof; a mechanical chassis, which is configured to mount said optical pickup, said disc rotation mechanism and said transfer mechanism thereon; a disc tray, which is configured to conduct storing and taking out of said disc; and a connector, which is configured to electrically connect between a circuit board for conducting driving control of said rotation mechanism and an external electronic apparatus, wherein a projection portion is provided on a reverse surface of said disc tray, at a portion facing to said connector at a position when said disc tray is stored, to be inserted into a gap between periphery of said connector and said housing, and thereby preventing fluid sounds (or wind sounds) generating due to high-speed rotation of the disc when high-speed recording/reproducing, from leaking into an outside of the apparatus, so as to reduce the noises therefrom. | 09-02-2010 |
20110055856 | Optical disc apparatus - An optical disc apparatus, presenting recording quality without degradation by an extreme temperature rise in an objective-lens drive mechanism in an optical pickup, includes a mechanical chassis on which a disc rotation mechanism, an optical pickup, and a transfer mechanism are mounted, a decorative plate that is a plate-shaped member located between the disc and the optical pickup and fixed on the mechanical chassis, a disc tray for loading and removing the disc, a circuit board for operation control, and an apparatus housing containing the components. A recess is formed in an indented shape in a portion of the mechanical chassis facing an outer peripheral region of the disc recording surface. An incline is formed in a position close to an opening of the disc tray for mounting the mechanical chassis and opposite the outer peripheral region of the disc recording surface, and slopes gently down to the recess. | 03-03-2011 |
20110197210 | OPTICAL DISC DRIVE - An optical disc drive with low vibration and low noise without risk of damage to components and injury caused by ejection of the disc tray with the rotating optical disc from a housing is provided by simple structure. In a disc-tray scheme of the optical disc drive, a brake member attached to the inside of the housing is placed to be in contact with the optical disc sliding thereon when the disc tray is in a predetermined position except the disc recording/reproducing position and the disc loading/unloading position, and to be connected to the disc tray when the disc tray is in the disc recording/reproducing position. | 08-11-2011 |
20110197211 | OPTICAL DISC DRIVE - In an optical disc drive, a degradation of traveling performance of an optical pickup under hard acceleration or hard deceleration in a random access operation or the like results in a degradation of recording/reproducing performance. Groove structure is provided between two gears of a guide feed provided in an optical pickup, and the groove forms bending structure. Thus, the engagement state between a screw gear and the gears of the guide feed is stabilized. This makes it possible to prevent tooth jumping and step-out from occurring in the gears during the traveling of the optical pickup, achieving stable traveling. In consequence, the recoding/reproducing performance of the optical disc drive can be improved. | 08-11-2011 |
