Patent ID: 8096021

Claim:
A hinge apparatus comprising: a first rotational shaft which rotates a first casing relative to a second casing in a vertical direction from a state where the first and second casings are folded down; a second rotational shaft which rotates the first casing relative to the second casing in a horizontal direction; a coupling member which couples the first rotational shaft and the second rotational shaft together perpendicularly such that an end portion of the first rotational shaft is overlapped with an end portion of the second rotational shaft; and an engagement member which restricts a rotation of the second rotational shaft by engagement of the first rotational shaft with the second rotational shaft when the first rotational shaft rotates, allows the rotation of the second rotational shaft when the first rotational shaft is in a first position, restricts a rotation of the first rotational shaft by engagement of the second rotational shaft with the first rotational shaft when the second rotational shaft rotates, and allows the rotation of the first rotational shaft when the second rotational shaft is in a second position; wherein the first rotational shaft and the second rotational shaft respectively have hollows through which a wire passes.
