Patent ID: 7706137

Claim:
An electronic apparatus, comprising: a first housing; a second housing; and a coupling unit that openably/closably and rotatably couples the second housing with the first housing, wherein the coupling unit is a biaxial coupling unit comprised of a rotation axis that vertically extends when the first housing is placed on a horizontal table, and is rotatably coupled to the first housing, and an opening/closing axis that is fixed to the rotation axis, horizontally extends, openably/closably supports the second housing with respect to the first housing, and rotates as the rotation axis rotates, and the coupling unit comprises a stopper that enables the rotation axis to rotate when the second housing is opened with respect to the first housing within a range of rotation-allowing opening angle that allows for rotation, and the stopper prohibits the rotation axis from rotating when the second housing is opened with respect to the first housing outside the range of rotation-allowing opening angle.
