A mobile communication device, comprising:
- a body comprising a front panel where a display is provided;
- a first QWERTY key unit having a plurality of QWERTY keys, the first QWERTY key unit body configured to be rotatable to transit from/to an open state to/from a closed state about a first axis perpendicular to the front panel;
- and
- a second QWERTY key unit having a plurality of the QWERTY keys, the second QWERTY key unit configured to be rotatable to transit from/to the open state to/from the closed state about a second axis perpendicular to the front panel,
- wherein the first QWERTY key unit is connected to the body using a first hinge formed by a first side edge of the body, and the second QWERTY key unit is connected to the body using a second hinge formed by a second side edge of the body opposite the first side edge,
- wherein the first QWERTY key unit is configured to be rotated about the first axis from/to the open state, in which a side of the first QWERTY key unit is positioned along the first side edge of the body, to/from the closed state, in which the side of the first QWERTY key unit is positioned along the first side edge and in a direction opposite to that of the open state, and
- wherein the second QWERTY key unit is configured to be rotated about the second axis from/to the open state, in which a side of the second QWERTY key unit is positioned along the second side edge of the body, to/from the closed state, in which the side of the second QWERTY key unit is positioned along the second side edge and in a direction opposite to that of the open state.
