Claim:
A roller nanoimprint apparatus continuously transferring nanosized protrusions to a surface of a workpiece film by rotating a mold roller, the roller nanoimprint apparatus comprising: a hollow roller having an opening and removably mounted thereon in a region defined by an inner circumference surface of the mold roller; and an elastic bag composed of a bag-like elastic film inflatable by fluid injection and arranged inside the hollow roller, the mold roller is a cylindrical body having an outer circumference surface with nanosized recesses formed thereon, the mold roller is mounted or demounted when the elastic bag is shrunken, and the mold roller is supported by inflating the elastic bag, thereby bringing a portion of the elastic bag, protruded from the opening of the hollow roller by the inflation, into contact with the inner circumference surface of the mold roller, and when thus-supported, the mold roller is rotated by rotating the hollow roller.
