  • Patent number: 8913373
    Abstract: Provided are a housing and an electronic device that ensure sufficient strength even when reduced in thickness. A carbon fiber layer included in the housing is disposed such that the orientation direction of carbon fibers is perpendicular to the lengthwise direction of the long sides of a back face panel, thus enabling improving the flexural strength of the back face panel. This enables increases in the number of carbon fibers per unit of area of the back face panel, and enables the length of each carbon fiber to be reduced. Accordingly, it is possible to cause the carbon fibers to flex less readily, thus enabling improving the strength in the flexing direction of the back face panel.

  • Patent number: 8669942
    Abstract: An operation unit has an operation surface for accepting an input operation. In a plan view, the operation surface has a rectangular contour including a plurality of sides and a plurality of corner portions. When each point at which extensions of adjacent two of the plural sides cross each other is defined as a virtual intersection, and when an intersection at which respective diagonals linking the virtual intersections cross each other is defined as a virtual center, the contour of the corner portion crosses the diagonal that passes through the virtual intersection and the virtual center, at a point between the virtual intersection in the vicinity of the corner portion and the virtual center. The corner portions is a specific corner portion having an intersection with the diagonal at a position closer to the virtual center than the adjacent two corner portions.

  • Patent number: 8593822
    Abstract: The present invention improves the operability when opening and closing a cover. Since the cover is curved such that the front face is in a concave form, when opening a memory slot, part of the cover is lifted from a first casing by simply removing a screw from the first casing and the cover. The cover can be detached from the first casing by holding the lifted portion of the cover, and, thus, the memory slot can be opened easily without using the weight of the cover. Accordingly, it is possible to improve the operability when attaching a memory module to the memory slot or when detaching a memory module from the memory slot.

  • Patent number: 8194402
    Abstract: An information processing unit of the present invention includes: a housing that incorporates an information processor; a handle arranged on one side surface of the housing; and support members that are arranged on the one side surface of the housing to protrude and support the handle. The support members respectively are arranged continuously from the one side surface to a pair of other side surfaces adjacent to the one side surface in a direction in which the handle is bridged. Each of the support members has a bent portion between the one side surface and each of the other side surfaces. Thus, a stress applied between the first housing and a handle mechanism when, for example, a user carries a notebook PC holding a handle can be dispersed, so that the handle can be fixed to the first housing with improved strength.

  • Patent number: 8149576
    Abstract: Since an information processing unit of the present invention includes a protrusion portion on a back face side of a first casing, it is possible to reduce an impact transmitted to a notebook PC when the notebook PC is placed in an upright position on the surface of a desk. Therefore, it is possible to prevent the notebook PC from being damaged. Furthermore, since the protrusion portion is provided to the back face side of the first casing, it is possible not to allow the notebook PC to stand self-supported in an upright position. Therefore, the notebook PC will not be placed carelessly in an upright position on the surface of a desk or the like; thus, it is possible to prevent the PC from being broken or damaged due to a fall.

  • Publication number: 20120069516
    Abstract: By forming a back wall in a holding member capable of holding a cable connector, an opening portion can be closed by the back wall in the case of producing a notebook computer not having a modular port. Therefore, one holding member can realize a notebook computer having a modular port and a notebook computer not having a modular port. This configuration makes it possible to eliminate the necessity to prepare a lid separately when the notebook computer does not have the modular port and to correspond to a plurality of specifications of communication interfaces with a reduced number of components. The reduction in the number of components reduces the cost of the notebook computer and the number of steps in assembling the notebook computer.

  • Patent number: 8107231
    Abstract: In the cover opening and dosing device of the present invention, among clearances between a cover and a first cabinet, a clearance 12a closest to protrusions on the first cabinet is made to have a larger width than other clearances. Thus, even when the protrusions are accidentally bumped against the wall or the like and the first cabinet in the vicinity of the protrusions is locally deformed, it is possible to absorb the deformation. Therefore, it is possible to reduce the possibility of the development of trouble in opening and dosing the cover.

  • Patent number: 8081445
    Abstract: A drainage structure of the present invention includes a drainage groove, a drain, and a groove portion. Thus, even in the case where a user accidentally spills a liquid such as water on an upper face of a first housing, intrusion of the liquid into a disk drive can be prevented, and damage to the disk drive can be prevented. Moreover, the drain is connected to the groove portion. Thus, a liquid that drains from the drain can be collected in the groove portion. Accordingly, the liquid can be prevented from spreading over a wide area, and adhesion of the liquid to various types of electric components disposed in a back face of the first housing can be prevented.

  • Patent number: 7948746
    Abstract: A cover opening/closing device of the present invention is formed so that a height of a rib to be in contact with a sealing member asymptotically decreases from a shaft toward an edge of a cover opposite to the shaft. With this configuration, the cover can be closed with only a small load imposed on the cover, whereby the operability in the opening/closing of the cover can be improved. Further, air-tightness of a recessed part provided with a disk drive sealed by the cover can be ensured.
