20090284856 | OPTICAL PICKUP DEVICE, AND OPTICAL DISC DEVICE - A guide shaft and a guide portion movably guide a lens holder for holding a collimator lens (i.e. correction lens) in an optical axis direction. A stepping motor rotates a screw shaft arranged in parallel to the optical axis direction. A nut member converts a rotating movement of the screw shaft into a rectilinear movement of the optical axis direction. An urging spring urges the lens holder against the guide shaft and the guide portion. The lens holder is driven in the optical axis direction along the guide shaft by the stepping motor, with a first contact portion and a second contact portion of the lens holder being contacted with the guide shaft, and a third contact portion of the lens holder being contacted with the guide portion by an urging force of the urging spring. The optical pickup device having the above arrangement allows for stable driving of a correction lens. | 11-19-2009 |
20090310460 | OPTICAL DISC DEVICE - An optical disc apparatus according to the present invention includes a disc rotation mechanism | 12-17-2009 |
20100050195 | OPTICAL DISK DEVICE - A disk drive according to the present invention includes: a cartridge holder; two guide walls arranged near the holder opening of the cartridge holder; a pair of opening/closing levers that have engaging portions to engage with portions of the cartridge and that turn; lever biasing springs for biasing the opening/closing levers; and an interlocking mechanism that makes the opening/closing levers rotate in synchronization with a clamp holder. The opening/closing levers turn such that when the cartridge starts to be inserted or finishes being ejected, the engaging portions get engaged with the cartridge with a narrower gap left between them than the gap between the guide walls and that when the cartridge gets loaded, the gap between the engaging portions becomes wider than the gap between the guide walls. | 02-25-2010 |
20100067078 | ACTUATOR - The present invention is directed to a bi-axial pivoting type actuator having a first movable section, a second movable section supporting the first movable section, and backlining.
