The key board mounting portion comprises an opening which allows a wiring electrically connecting the keyboard and the circuit module to be passed therethrough. An area of the opening is equal to or less than half of an area of the keyboard mounting portion.

Abstract: An electronic apparatus comprises a display housing supported by a main unit, and a display panel contained in the display housing. The display housing has a supporting wall and an upper wall. The display housing contains an antenna board. The antenna board is interposed between the display panel and the supporting wall, and has an antenna portion which projects outside the display housing and pierces through the upper wall. A nonconductive cover which covers the antenna portion is attached to the upper wall of the display housing.

Abstract: A main circuit board is mounted on a main body. A switch circuit board is held in a mounting portion such that switches face upwards. As the switch circuit board is held in the mounting portion, positioning projections formed on a bottom wall are pierced through positioning holes, respectively, and thus the positioning of the switch circuit board inside the mounting portion can be easily carried out. A switch cover is provided above the switch circuit board held in the mounting portion. A plurality of projections projecting downwards from the inner surface of the switch cover are brought into contact with the upper surface of the switch substrate. As these projections press the upper surface of the switch substrate, the up-and-down rattling of the switch circuit board inside the mounting portion can be prevented.

Abstract: An electronic apparatus comprises a display housing supported by a main unit, and a display panel contained in the display housing. The display housing has a supporting wall and an upper wall. The display housing contains an antenna board. The antenna board is interposed between the display panel and the supporting wall, and has an antenna portion which projects outside the display housing and pierces through the upper wall. A nonconductive cover which covers the antenna portion is attached to the upper wall of the display housing.

Abstract: An electronic apparatus includes a case which has a unit housing portion therein, a printed-circuit board which is built into the case in a portion other than the unit housing portion, and at least one unit which is selected from a group including a plurality of units having different occupied areas when arranged in a plane and stored in the unit housing portion.

Abstract: A rectangular heating section is so shaped as to touch the electronic component except corners of the rectangle when the surface of the electronic component does not parallel the heating section. For example, the heating section is formed to be smaller than the electronic component surface, to be a rectangle which is smaller than the electronic component surface and comprises rounded corners, to be an octagon which is smaller than the electronic component surface and is formed by cutting off corners of the rectangle, or to be an octagon which is larger than the electronic component surface and is formed by cutting off corners of the rectangle. A die is prevented from being damaged due to a contact with the heating section of a cooling module at a given point of the die according to a mounting error or a usage state.

Abstract: A brake hinge configured to connect a main housing and a display housing, one of which is rotatable with respect to the other, and to apply a predetermined torque to the housings, has a torque-generating section shaped like a hollow cylinder. The torque-generating section comprises a first member and a second member. The first member has a first guiding path in its one end portion. The second member is aligned coaxial with the first member, holds the other end portion of the first member, allowing the first member to rotate, and has a second guiding path in its middle portion. The torque-generating section holds a middle portion of a harness that connects the main housing and the display housing. The first guiding path guides one end portion of the harness into one of the housings. The second guiding path guides the other end portion of the harness into the other of the housings.

Abstract: An apparatus and method for releasing a load stress imposed during operation of a handheld electronic device includes a thin housing body defining an opening for mounting a keyboard panel. The keyboard panel has a relatively low rigidity. A spacing structure is provided to maintain a predetermined distance between a surface of a semiconductor package mounted on the keyboard panel and the thin housing body. The height of the spacing structure is greater than the height of the semiconductor package so that the predetermined distance is maintained when the keyboard panel is elastically deflected.

Abstract: A portable information-processing apparatus comprising a housing having a first wall and a second wall opposing the first wall. A first manual operating member is provided on the first wall and exposed. A second manual operating member is provided on the second wall, is exposed, and facing away from the first manual operating member. In the housing there is provided a reinforcing plate for receiving the pressure which is generated when the first manual operating member is operated. The reinforcing member is located between the first and second operating members and supported by the first wall. The first and second manual operating members are supported by the first wall. The reinforcing plate is placed apart from the second manual operating member, forming a gap. The second wall has a projection which abuts on the reinforcing plate.

Abstract: A circuit module comprising a circuit board, a function component, and a heat sink. The circuit board has a number of circuit components and a circuit element which generates heat while operating. The function component is secured to the circuit board by screws. The heat sink is connected to the circuit board by the screws, for radiating heat generated by the circuit element.

Abstract: A small or very small notebook type or palmtop type personal computer has a display device which is attached to a computer main body in an openable and closable fashion. The display device has a display panel body coupled to the computer main body in an openable and closable fashion by hinge mechanisms provided at both ends of the computer main body, and a display panel provided on the computer main body. The bottom portion of the display panel is the horizontal area between both hinge mechanisms. Therefore, the display panel is arranged within the limited space of the display panel body in such a way as to be able to avoid both hinge mechanisms even when the display panel constitutes, for example, a horizontally elongated display screen.
