Patent ID: 8777185

Claim:
A rotation device comprising a cylindrical rotating body that is configured to be rotatable about an axis, a pair of brackets positioned substantially perpendicular to the axis of the cylindrical rotating body and respectively rotatably supporting axial ends of the cylindrical rotating body, a first motor attached to one of the brackets, a second motor attached to the other of the brackets, a pair of rotating body-side gears that are coaxially secured to both axial ends of the cylindrical rotating body, a first gear connected to the first motor and meshed with one of the rotating body-side gears, and a second gear connected to the second motor and meshed with the other of the rotating body-side gears, wherein the pair of brackets are oppositely positioned on both axial ends of the cylindrical rotating body, and the brackets are rotatable relative to each other about the axis of the cylindrical rotating body, and wherein the brackets have a guide mechanism formed therein that is configured to guide one of the brackets having the first motor, and the other of the brackets having the second motor, so as to allow the brackets to rotate about the axis of the cylindrical rotating body relative to each other.
