  • Patent number: 8295053
    Abstract: A mounting component includes a fixed frame to be fixed to a board and a sliding frame. The fixed frame includes first and second fixed side plates having through holes formed in positions corresponding to engaging holes of an electronic component, and first and second fixed arms connecting the first and second fixed side plates. The sliding frame includes first and second sliding side plates including engaging pins to be inserted via the through holes into the engaging holes of the electronic component, first and second sliding arms extending from the front and back ends of the first sliding side plate, and third and fourth sliding arms extending from the front and back ends of the second sliding side plate. The first, second, third, and fourth sliding arms are configured to slide the first and second sliding plates away from the first and second fixed side plates.

  • Patent number: 8264838
    Abstract: A display device includes: a display-device main unit having a display screen on the front; a standing pole; a first support member having mounting holes arranged vertically with a predetermined pitch and fixed to the pole; and a second support member having threaded holes arranged vertically with the same pitch as the predetermined pitch and fewer than the mounting holes. The second support member is fixed to the back of the display-device main unit. One of the first support member and the second support member has an engaging hole, and the other has projections arranged vertically with the same pitch as the predetermined pitch and each capable of being inserted into the engaging hole. According to a projection that is one of the projections and inserted into the engaging hole, mounting holes among the mounting holes and as many as the threaded holes are connected to the threaded holes, respectively.

  • Patent number: 8052306
    Abstract: An electronic apparatus includes: a cover having an optically-transparent base and a shielding film for making an inside invisible; and a substrate disposed inside and covered by the cover, the substrate being mounted with a light emitting element for emitting light toward the cover and a touch sensor disposed at a position surrounding the light emitting element to detect a touch of an outer surface of the cover by a finger. The electronic apparatus further includes an icon board disposed at a position between the substrate and the cover and having a light transmitting section formed to define an outline of light emitted by the light emitting element toward the cover. The shielding film shows light emitted by the light emitting element and passing through the icon board.
