Abstract: A portable information processing apparatus is configured to dissipate heat generated in a cabinet mainly from a part which a user hardly touches, and thus the temperature at a palm rest is suppressed. The cabinet includes a heat conducting spacer 16 provided over a heat-generating component 15 to conduct heat thereof, a heat absorption area 10ah to absorb the heat of the heat-generating component 15 through the heat conducting spacer 16, and a heat conduction obstructing area 10rb provided on a heat conduction path between the heat absorption area 10ah and the palm rest 11 to reduce a cross-sectional area of the heat conduction path. Accordingly, heat conduction from the high-temperature heat generating component 15 to the palm rest 11 is restricted, and thus the temperature of the palm rest 11 can be limited.

Abstract: An extension device 5 is engaged in a connector provided on one side of a lower case 102 of a cabinet 100 of an PIP apparatus PI. An adjustable foot 6 is provided on the bottom surface 102u to adjust the extension device 5 and the cabinet 100 in height. Therefore, the cabinet 100 can be horizontally placed on a plane. When the extension device 6 is approximately equal in height to the lower case 102, the adjustable foot is retracted into the lower case 102. Therefore, the thickness of the PIP apparatus PI can be minimized.

Abstract: A display device includes: a support stand; an arm unit mounted on the support stand; and one or more display sections mounted on the arm unit, wherein the arm unit includes one or more arms for respectively supporting the one or more display sections, the one or more arms are rotatably attached to the arm unit so that the one or more display sections can be moved to such positions that a user can comfortably observe the one or more display sections, and the one or more display sections are each rotatably attached to a respective one of the one or more arms so that the one or more display sections can be moved to such positions that the user can comfortably observe the one or more display sections.
