A hinge structure for changing front/rear sides of a cover when the cover is opened/closed is provided to allow a user to watch an item displayed on a front surface of a cover immediately when he/she opens the cover. A hinge body part(300) includes a bevel gear(350) mounted at a central shaft at which a main body part(700) and a cover part(600) make a hinge movement mutually, and is installed at hinge mounting parts(780,788). A rotatable body part(100) is rotated in a direction perpendicular to the central shaft, includes a bevel gear(150) contacting with the bevel gear(350) and a cover coupling part(170) coupled with the cover part(600).
