Abstract: A gear linkage device with real time check. The gear linkage device with real time check includes a first gear link and a second gear link. The first gear link includes a flange provided with a notch and a plurality of first toothed portions on the lateral surface thereof. The second gear link includes a finger corresponding to the notch and a plurality of second toothed portions on the lateral surface thereof, corresponding to the first toothed portions. When the first gear link engages with the second gear link, the finger engages with the notch so as to avoid the misalignment between the first gear link and the second gear link, problems associated therewith.

Abstract: An optical disk reading device has a substrate below which a CD is loaded, a base element fixed to an opening of the substrate, a movable element, a rotation part that movably connects the movable element to the base element in a manner such that the movable element moves rotationally and vertically with respect to the base element, and a clamp coupled to the movable element and extending through the opening of the substrate when the movable element moves with respect to the base element.

Abstract: A disc drive with a foldable support. The disc drive comprises a main body and a foldable support mounted thereon. The foldable support includes a first strut and a second strut. One end of the first strut and the second strut are pivoted on the main body. The other end of the first strut slides on and along the second strut so that the disc drive can be deployed diagonally to save space.

Abstract: A disk reading device has a housing having a disk receiving space provided therein, a first rod having a first guide pin, a second rod pivotably coupled to the first rod at a pivot point in a manner such that the first and second rods achieve a scissoring movement about the pivot point, with the second rod having a second guide pin. The device also includes a locking mechanism for locking the first and second rods at a fixed position, and a detection mechanism coupled to the first rod for detecting the size of a disk that is being inserted into the disk receiving space. The locking mechanism unlocks the first and second rods when a disk having a first size contacts the detection mechanism, and the locking mechanism maintains its lock on the first and second rods when a disk having a second size smaller than the first size is inserted into the disk receiving space.

Abstract: A disk reading device operates in both a suction mode and a cover-lifting mode. The device has a lower cover having a wall with an elongated opening provided in the wall, an upper cover that is connected for pivoting movement with respect to the lower cover, and a disk receiving space between the lower and upper covers. The disk receiving space is accessible via the elongated opening in a suction mode and by opening the upper cover with respect to the lower cover in a cover-lifting mode. A disk is drawn via the elongated opening into the disk receiving space, or a disk can be manually placed in the disk receiving space by opening the upper cover with respect to the lower cover. The device also includes a switch that switches operation of the disk reading device from the suction mode to the cover-lifting mode.

Abstract: A disk-positioning device for a slot-in optical disk drive. The device can identify the size of the optical disk inserted in the slot-in optical disk drive. The disk-positioning device includes a substrate, a positioning rod, a locking rod, a floating lever, and a sliding plate. The positioning rod is linearly movable on the substrate, and the locking rod is slidably connected to an end of the positioning rod, providing the positioning rod with a location in which to position the optical disk. The floating lever is slidably connected to the other end of the positioning rod. The sliding plate activates a disk-fixing device to fix the optical disk to a spindle of the drive.

Abstract: A reed-type clamp device. The reed-type clamp device comprises a main body, a rotating ring, a reed and a clamp. The rotating ring has a ring portion and a lever portion. The ring portion has a plurality of protrusions formed on the inner circumference of the ring portion. The rotating ring is disposed on the main body and rotates clockwise and counterclockwise. A plurality of swing arms are extended from the outer edge of the reed. The swing arm has an outer end fixed on the main body and a driving portion. The protrusions of the rotating ring touch the driving portions. The clamp is fitted in the reed. By rotating the rotating ring, the swing arms of the reed fixed on the main body are pushed upward or downward such that the clamp can be moved upward or downward.
