Abstract: In a personal computer, preferably a lap-top-type personal computer, first latch members (or sections) and second latch members (or sections) are provided on a bezel surrounding a periphery of a keyboard. The first and second latch members serve to support one side of the keyboard. By having a bottom surface of the second latch members made a sloping surface, when a user pushes the keyboard upward with a finger from below the keyboard slides backward at a slope without interfering with the first latch members. As such, the front part of the keyboard is released from the latching by the first latch members and the second latch members and can be easily and simply removed.

Abstract: A slope of an HDD door comes in contact with a slope formed on a lower wall. At this time, when screws of the HDD door are fastened, a fastening force is generated at the HDD door in a direction parallel to the plane direction of the PC housing. The HDD united with the HDD door moves slightly in a parallel direction in proportion to the fastening degree of the screws. At this time, the slope slides to go up on the slope, so the HDD moves slightly upward. When the screws are fastened fully up to the allowable torque, the HDD is firmly attached to the upper wall.

This allows the same status display to be provided in a plurality of directions by one light source.

Abstract: To obtain connector connecting structure that makes it easy to connect connectors when a mounted part is mounted in a part-receiving part. In a keyboard unit mounted in a PC body of a notebook PC, a connector implemented on a flexible cable is movably supported through a cushion, which is made of urethane rubber and is fixed on a installation side 14B of the keyboard unit, and a support plate fixed to the cushion. Owing to this, by just mounting the keyboard unit in the PC body, the connector is connected to the connector in the PC body side, and hence connection becomes simple. Therefore, even if the misalignment between the connectors and arises, the connector moves according to an amount of the misalignment, and hence adequate connection can be performed.

Abstract: A battery connector structure and a battery pack are described in which good electrical contact can be maintained even if an external force is applied around the connectors. The battery connector structure includes a male connector that consists of comb-shaped electrodes with a positioning plate, and a female connector having slits into which the comb-shaped electrodes and the positioning plate are inserted to make electrical connections with the comb-shaped electrodes in such a way that the connectors can be connected and disconnected. A projection is provided at the end of the positioning plate and a hollow that accepts the projection is provided in the slit of the female connector or in a system in which the female connector is provided. In addition, the battery pack has this battery connector structure.

Abstract: A keyboard includes a plurality of keys arranged in at least one continuous row and formed of a key member and a cover member. These members are combined by inserting positioning pins of the cover member into holes of the key member. Curved portions are provided at a plurality of positions in side support portions of the key member. Even if the cover member and the key member are produced with manufacturing errors in alignment, the curved portions may be deformed to prevent misalignment between openings on the cover member and key top portions on the key member when the positioning pins are inserted into the holes. Elastically deformable arms extending from the side support portions of the key member support the key tops and enable the key tops to move up and down.
