  • Patent number: 8514568
    Abstract: An electronic device having a rotatable support is provided. A main body includes a first cylindrical engaging hole with a plurality of first internal gear teeth. A support body includes a second cylindrical engaging hole with a plurality of second internal gear teeth. A gear includes a first portion inserted in the first engaging hole and engaging with the first internal gear teeth, and a second portion inserted in the second engaging hole and engaging with the second internal gear teeth, to restrict the support body from rotating with respect to the main body. A spring member is compressed between the gear and main body in the first engaging hole, to urge the gear to move away from the main body. A button depressibly mounted on the support body is depressed to move the gear out of the second engaging hole, thereby disengaging the support body from the gear.

  • Patent number: 8363386
    Abstract: An electronic device includes a main body and an interface shielding cover. A recess is defined in the main body by a vertical wall and a bottom. Two openings are defined in the rear cover between the vertical wall and the bottom wall, two stop walls adjacent to the openings include a first engaging side and a second engaging side. The interface shielding cover includes a pair of elastic arms rotatably connected to the rear cover. Each elastic arm includes a first protrusion and a second protrusion distinctly oriented from the first protrusion. The interface shielding cover is rotatable relative to the rear cover between a closed position where the first protrusion abuts against the first engaging side to retain the cover in the closed position, and an open position where the second protrusion abuts against the second engaging side to retain the cover in the open position.
