Claim Text:
1. An optical recording medium production device in which an information signal layer is provided on a substrate, comprising: a substrate positioning pin vertically movable that performs positioning to a center hole of the substrate; a substrate holding portion that performs the positioning of the substrate using the substrate positioning pin to hold the substrate; a cleaner having a gas ejection portion that ejects gas toward a surface of the substrate held by the substrate holding portion, and a gas suction portion that suctions the gas; and a substrate positioning pin fixing portion that can press the substrate positioning pin downward, and is configured so as not to come into contact with an inner circumferential side surface of the center hole of the substrate; wherein the substrate positioning pin fixing portion descends inside the center hole of the substrate held by the substrate holding portion so as to form a gap in the vicinity of the inner circumferential side surface of the center hole of the substrate, and presses and fixes the substrate positioning pin, and in the state, the cleaner performs the ejection and suction of the gas.
