Abstract: According to one embodiment of the invention, a heat pipe features a pipe-shaped container in which an operating fluid is sealed, and a wick provided inside the container. The container has a flat heat-receiving end portion, a heat-radiating end portion being flattened in a direction different from that of the heat-receiving end portion, and a middle portion connecting the heat-receiving end portion and the heat-radiating end portion. The middle portion has a circular cross section.

Abstract: A storage device includes a chassis, and a circuit board supported by the chassis and holding a circuit component thereon. The circuit board is covered with an insulating sheet, and the insulating sheet has an opening at a position opposed to the circuit component. The opening is covered with a thermal conduction sheet from an opposite side to that of the circuit board, and the thermal conduction sheet is thermally connected to the circuit component through the opening.

Abstract: The electronic apparatus comprises a housing having a bottom wall, and a functional component contained in the housing. First and second gaps are created between the functional component and the bottom wall. The second gap is larger than the first gap. The functional component is supported in the housing via a supporting member. The supporting member is interposed between the functional component and the bottom wall, and has a first part positioned in the first gap and a second part positioned in the second gap. The second part has lower rigidity than the first part.

Abstract: An electronic apparatus has a housing, a heat generating component arranged in the housing, a heat pipe including a flat heat receiving surface integrally formed at one end, a deformable thermal conductive material, and a heat radiation member. The deformable thermal conductive material is arranged between the flat heat receiving surface and the heat generating component, and thermally connects the flat heat receiving surface and the heat generating component. The heat radiation member is thermally connected to the other end of the heat pipe.

Abstract: A notebook-type personal computer of this invention uses three types of recording media, which are a CD-ROM, a smart-media card and an SD memory card. The personal computer comprises a main housing. The personal computer further comprises a CD-ROM unit, a smart-media card unit and an SD memory card unit, all incorporated in the main housing. The main housing has, in one side, a CD-ROM tray port, a SD memory card port and a smart-media card port. The CD-ROM unit, smart-media card unit and SD memory card unit are arranged such that the SD memory card port and a smart-media card port are located side by side and above the CD-ROM tray port.

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: An electronic apparatus system comprises an electronic apparatus body such as a portable computer, and an extension station for use in extending the functions of the electronic apparatus body. The extension station has a mount portion on which the electronic apparatus body is detachably mounted, a device storage section in which an extension device for extending the functions of the electronic apparatus body is removably stored, and an ejector for discharging the extension device from the device storage section. The ejector has an eject lever manually operable at the time of discharging the extension device. The eject lever has an operation section exposed to the mount portion. The extension station includes a rotatable cover which is held in a closed position by an extension portion of the cover which extends toward the mount portion of the extension body. The extension portion of the cover is located under the portable computer when the portable computer is mounted on the mounting portion.

Abstract: An apparatus includes a housing which incorporates a recording and reproducing function which includes a tape diving section, an opening portion formed in a front wall of the housing, and a tray unit which can be horizontally inserted and removed through the opening portion and in which first and second cassettes can be arranged on top surfaces of front and back regions, respectively. A cassette driving unit including pantagraph mechanisms and, a motor for driving the tray, and gears to move the tray unit and selectively load one of the cassettes in the tape driving section. Pop-up mechanisms and provided in the front and back regions of the tray, respectively. When the tray unit is pulled and the entire front region and a portion of the back region are located outside said housing, the pop-up mechanisms lift the front end of the cassette loaded in the back region to direct it toward an obliquely upper position.

Abstract: A cassette door (211) is attached to a slot of a cabinet (210) through which a tray (59) is inserted into and pulled out of the cabinet, serving to freely open and close the slot, and a door lock means (86, 87) for locking the cassette door (211) at a slot-closed position is associated with slot-in and projected movements of the tray (59) to lock the cassette door (211) at the slot-closed position and unlock it from the slot-closed position.

Abstract: A tray assembly (59) is provided with a lever (72) for unlocking the lid lock of a cassette (200). It is detected whether or not the lever (72) works to unlock the lid lock of the cassette (200), associating with the slot-in movement of the tray assembly (59), and the slot-in movement of the tray assembly (59) is prevented when the cassette lid unlock lever (72) is left inoperative.
