Patent ID: 8099143

Claim:
An information processing apparatus, comprising: an opening/closing mechanism in which a first casing and a second casing are hinge-connected via a hinge unit and the first casing and the second casing are opened and closed via the hinge unit; and a rotation mechanism in which the second casing is rotated about a twisting central axis which protrudes and contacts the hinge unit to rotatably support the second casing, wherein in a closed state where one face of the first casing and one face of the second casing are overlapped one another, a clearance between the first casing and the second casing is set to have a first distance, and in another closed state where the one face of the first casing and the other face of the second casing are overlapped one another by rotating the second casing about the twisting central axis, the clearance between the first casing and the second casing is set to have a second distance different from the first distance; wherein in the closed state where the one face of the first casing and the one face of the second casing are overlapped one another, when the clearance between the first casing and the second casing is set to have the first distance, a central axis of the face of the second casing is shifted by the first distance with respect to the twisting central axis in a direction where the second casing approaches the first casing.
