    摘要： Disclosed herein is a pivotable sunshade clip for spectacles, which can be easily pivoted upward or downward while it is attached to the spectacles without risk of unintentional separation, and can eliminate any unpleasant pressure exerted upon a wearer by virtue of a weight reduction thereof. The pivotable sunshade clip comprises a spectacles bridge and a sunshade bridge which are attached to frames of spectacles and the sunshade clip, respectively. Both the bridges are made of the same material as that of the frames. The spectacles bridge is centrally provided with a stator having a pair of magnets inserted at front and upper sides thereof, respectively. The sunshade bridge is centrally provided with a mover. The mover is adapted to be pivoted upward or downward to be magnetically attached to one of the magnets inserted in the stator, thereby maintaining the sunshade clip in an opening or closing position relative to the spectacles. Such a mover includes a center stator recess for receiving the stator, and pivot bridge portions located at both sides of the stator recess, respectively. Each of the pivot bridge portions has a fitting groove for allowing the spectacles bridge to be fitted therein while forming a pivot center point. The mover also includes a magnet inserted in the stator recess and adapted to be magnetically attracted to one of the magnets of the stator.

    摘要： A disc cartridge for receiving a disc includes a case which accommodates the disc and at least one centering spring which prevents deviation of the disc in the case. Thus, a gap in which the disc moves in the disc cartridge is restricted so as to reduce a length in which a disc clamp of the disc contacts a disc clamp guide inside a disc drive system. Accordingly, the height of the disc clamp is reduced so as to reduce the thickness of the disc cartridge and miniaturize the disc cartridge.
