1. An electronic apparatus comprising:
a first chassis in which a heat generating element is mounted;
a second chassis adjacent to the first chassis;
a hinge device that connects the first chassis to the second chassis such that the first chassis and the second chassis can be rotated relative to each other between a 0-degree attitude, at which the first chassis and the second chassis are stacked to overlap each other in a surface normal direction, and a 180-degree attitude, at which the first chassis and the second chassis are both arranged in a direction perpendicular to a surface normal direction; and
a display having a fold region that is across the first chassis and the second chassis and is folded as the first chassis and the second chassis rotate relative to each other,
a first plate stationarily affixed to the display;
a second plate stationarily affixed to the display;
wherein the hinge device has:
a metallic hinge main body that extends along adjacent end portions of the first chassis and the second chassis, and that stretches across the adjacent end portions;
a metallic first support plate that extends along the adjacent end portions on an inner surface side of the first chassis, is connected to the hinge main body in a relatively rotatable manner, is pivotally connected to the first plate, is relatively movable with respect to the inner surface of the first chassis, and supports a back surface of the display between the 0-degree attitude and the 180-degree attitude; and
a metallic second support plate that extends along the adjacent end portions on an inner surface side of the second chassis, is connected to the hinge main body in a relatively rotatable manner, is pivotally connected to the second plate, is relatively movable with respect to the inner surface of the second chassis, and supports the back surface of the display between the 0-degree attitude and the 180-degree attitude,
the electronic apparatus further comprising a flexible heat conductive member inside the first chassis, and
the flexible heat conductive member thermally connecting a heat receiving member, which receives heat from the heat generating element, to the first support plate.
