  • Patent number: 6561421
    Abstract: A Universal Serial Bus (USB) card reader mainly has a long strip-shaped main body wherein an opening disposed on one of the longitudinal sides thereof; a circuit board is mounted inside the main body; a USB plug and an inserting slot corresponding to the opening of the main body are disposed on a transversely lateral side of the said circuit board; after the circuit board is secured to the main body, the said USB plug fitly projects outwardly at one end of a transverse side to allow a flash memory card to insert into the inserting slot through the longitudinal opening at 90 degree with the said USB plug so as to save the inserting space of the card reader; furthermore, when not being inserted by a flash memory card, the card reader is convenient for carrying and storage due to the reduced volume.

  • Patent number: 6149028
    Abstract: This structure is an integrated cup-handle and shaft structure, whose principal components are a cup-stand and handle. The said cup-stand has a circular base. From the said base, extending up, is a semi circular safety-wrap and on its outer wall, at its central point, protrudes a handle. Additionally, from the safety-wrap's central point and from its top, extends a stem. The said stem's top is folded down at an angle, then lips up forming a clip, which all holds the cup when it is placed in the cup-stand. This clip securely holds the cup's mouth so the handle may be grasped and the cup lifted up.
