Patent ID: 7322787

Claim:
A substrate reversing device that reverses a substrate which has first and second substantially circular surfaces opposite to each other and a circumference, and each said surface having a respective peripheral portion, comprising: first and second movable members arranged opposite to each other for receiving said substrate such that the first and second surfaces are opposite to said first and second movable members respectively; a plurality of first supporters that are provided on said first movable member and support the first peripheral portion of the substrate; a plurality of second supporters that are provided on said second movable member and support the second peripheral portion of the substrate; a driving device that moves at least one of said first and said second movable members relative to the other such that said plurality of first supporters and said plurality of second supporters are selectively transferred between a first state in which said plurality of first supporters and said plurality of second supporters are spaced apart from one another and a second state in which said plurality of first supporters and said plurality of second supporters are closer to one another; and a reversing device that reverses said first and second movable members in said second state about an axis parallel to the first and second surfaces; wherein corresponding pairs of said first supporters and said second supporters are arranged in positions shifted away from each other in a direction along the circumference of the substrate.
