Abstract
A roll holder includes a plurality of holder members to fit in and hold axial ends of any of a first roll with a first inner diameter and a second roll with a second inner diameter greater than the first inner diameter. Each holder member includes a base opposed to an axial end of any of the first roll and the second roll; a plurality of support switches; and a lock. The support switch is movable in an axial direction between a support position to support the second roll with the second inner diameter and a retracted position retracted from the support position to support the first roll with the first inner diameter. The lock locks movement of the plurality of support switches and releases locking of movement of the plurality of support switches when each of the plurality of holder members is fitted in the first roll.
