The recording medium production device, comprising: a substrate positioning pin vertically movable that performs positioning to a center-hole of substrate; a substrate holding portion that performs positioning of substrate using the substrate positioning pin to hold substrate; a cleaner having a gas ejection portion that ejects gas toward surface of substrate held by the substrate holding portion, and a gas suction portion that suctions gas; and a substrate positioning pin fixing portion that can press the substrate positioning pin downward, configured so as not to contact with an inner circumferential side surface of the center-hole of substrate; wherein the substrate positioning pin fixing portion descends inside the center-hole of substrate held by the substrate holding portion to form gap near the inner circumferential side surface of the center-hole of substrate, and presses and fixes the substrate positioning pin, and then the cleaner performs ejection and suction of gas.
