Claim:
An electronic device comprising: a first housing that includes an inlet and an outlet on one end; a second housing; and a linkage section that links the second housing to the first housing such that the second housing can be opened and closed, wherein the linkage section holds the second housing so that the second housing is rotatable around a rotation axis which passes through the one end of the first housing, when the second housing is closed, the second housing covers a top surface of the first housing except for a region on the top surface which is positioned above the rotation axis and extends along the rotation axis, and when the second housing is opened, the second housing is rotated to be away from the top surface, the outlet is exposed both when the second housing is closed and when the second housing is opened, by being arranged on a back surface of the first housing which contacts with the top surface by a common side of the back surface and the top surface and which extends along the rotation axis, and the inlet is exposed both when the second housing is closed and when the second housing is opened, by being arranged a distance away from the outlet, on a boundary region between the back surface and the region on the top surface.
