An image photographing apparatus includes an apparatus main body having a mounting portion. A display unit having a display is mounted on the mounting portion. The display unit can be positioned at first pose where the display unit faces the bottom surface of the mounting portion, or at a second pose where the display unit faces away from the bottom surface of the mounting portion. A hinge unit connects the display unit to the main body so that the display unit is openable and closable to and from the mounting portion with respect to a first axis. The hinge unit also has a second axis that allows the display unit to be moved from the first pose to the second pose. A locking unit locks the display unit mounted on the mounting portion in the first or second pose.
