摘要:
An electronic apparatus includes a first housing; a second housing; and a coupling unit that openably/closably and rotatably couples the second housing with the first housing. The coupling unit is a biaxial coupling unit having: 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. The coupling unit includes a stopper to rotate the rotation axis-only when the second housing is opened with respect to the first housing within a range of rotation-allowing opening angle that allows for rotation.
