Abstract: A paper-sheet-separating/conveying roller 10 includes a rubber member (conveying member 11A or 11B) having a specific diameter and a through-hole at the center thereof; a core (protrusion 12b or 12c) inserted in the through-hole; and supports which have a diameter greater than that of the core and smaller than that of the rubber member and which sandwich the rubber member from both sides, wherein a member (fixing member 12) having the support which is in close contact with one side surface of the rubber member and a member (holding member 13) having the support which is in close contact with the other side surface of the rubber member are aligned and fixed in an axial direction.

Abstract: A disc-loading roll is composed of a rubber elastic body formed by use of a mold and having a cylindrical outer surface whose diameter changes along an axial direction. The disc-loading roll comes into contact with a peripheral edge portion of a disc so as to load the disc. An outer circumferential surface of the roll is an irregular surface which is formed by means of the mold. The irregular surface has a ten-point mean roughness Rz of 0.5 to 10 ?m and a mean irregularity interval Sm of 15 ?m or less.
