摘要:
In an optical disc fabricating apparatus, when the disc substrate is lowered from the tip of a disc inserting portion at a center pin down to a disc supporting portion, a disc urging portion of an alignment lever is pressed by a disc substrate, to be thus pushed in toward an inner periphery and a sheet urging portion is pushed out toward an outer periphery, so as to press the inner peripheral surface of a cover sheet so that both of the cover sheet and the disc substrate are urged in an alignment direction. Thus, it is possible to eliminate play generated between the inner peripheral surface of the cover sheet and the outer peripheral surface of a sheet inserting portion and play generated between the inner peripheral surface of the disc substrate and the outer peripheral surface of the disc inserting portion.
