Abstract
A roll holder is inserted with a hollow tube of one of a first roll having a first inner diameter and a second roll having a second inner diameter greater than the first inner diameter. The roll holder includes a holder and a cam assembly that are supported by a support shaft and movable in an axial direction of the support shaft. The cam assembly includes an abutment and a cam. The abutment contacts a lateral end of the second roll in the axial direction of the support shaft. The cam presses against one of a first presser and a second presser of the holder in a radial direction of the support shaft to cause the one of the first presser and the second presser to press against and hold an inner circumferential face of the hollow tube of the one of the first roll and the second roll.
