Patent ID: 7878213

Claim:
A reversing device comprising: a first holding mechanism configured for holding a substrate in a state vertical to a first axis; a second holding mechanism configured for holding a substrate in the state vertical to said first axis; a supporting member that supports said first and second holding mechanisms so that said first and second holding mechanisms overlap with each other in a direction of said first axis; and a rotating device that integrally rotates said supporting member together with said first and second holding mechanisms around a second axis substantially vertical to said first axis; wherein said first holding mechanism is configured to hold the substrate independently from said second holding mechanism, and said second holding mechanism is configured to hold the substrate independently from said first holding mechanism; wherein said first and second holding mechanisms include a common reverse holding member having one surface and the other surface that are vertical to said first axis, said first holding mechanism includes a plurality of first supporters that are provided on said one surface of said common reverse holding member and support a periphery of the substrate, a first reverse holding member provided so as to face said one surface of said common reverse holding member, a plurality of second supporters that are provided on a surface of said first reverse holding member facing said common reverse holding member and support the periphery of the substrate, and a first driving mechanism that moves at least one of said first reverse holding member and said common reverse holding member so that said first reverse holding member and said common reverse holding member are selectively shifted between a state where said first reverse holding member and said common reverse holding member are spaced apart from each other in the direction of said first axis and a state where said first reverse holding member and said common reverse holding member are close to each other, and said second holding mechanism includes a plurality of third supporters that are provided on said other surface of said common reverse holding member and support the periphery of the substrate, a second reverse holding member provided so as to face said other surface of said common reverse holding member, a plurality of fourth supporters that are provided on a surface of said second reverse holding member facing said common reverse holding member and support the periphery of the substrate, and a second driving mechanism that moves at least one of said second reverse holding member and said common reverse holding member so that said second reverse holding member and said common reverse holding member are selectively shifted between a state where said second reverse holding member and said common reverse holding member are spaced apart from each other in the direction of said first axis and a state where said second reverse holding member and said common reverse holding member are close to each other.
