Classification: CPC H  B | IPC B  H

Claim 0:
1. A substrate support mechanism, comprising:
a first support part that has a first contact region capable of coming into contact with a peripheral edge of a substrate in a closed state;
a second support part capable of supporting a bottom surface of the substrate, wherein the second support part comprises a tip with a second contact region, and wherein the second contact region is configured to contact and support said bottom surface;
a first support part moving part that can move the first support part from the closed state to an open state,
wherein, when the substrate is supported on the second support part, the first support part comprises a first extending portion that extends below the bottom surface of the substrate such that a portion of the first extending portion is located vertically below the substrate when the substrate is supported on the second support part, wherein the first support part comprises a second extending portion that extends from the first extending portion, and wherein the first contact region is provided at a tip portion of the second extending portion;
wherein a first magnet is provided in the first extending portion, wherein a second magnet is provided between the first extending portion and the substrate when the substrate is supported on the second support part, and wherein the first support part is configured to swing into the closed state by a repulsive force between the first magnet and the second magnet.
