- a housing that is open in a first direction, the housing providing an accommodation space for accommodating therein either the first roll or the second roll such that the first sleeve or the second sleeve extends in a second direction perpendicular to the first direction;
- a first adjuster provided in the accommodation space;
- a second adjuster provided in the accommodation space, the first adjuster and the second adjuster facing each other in the second direction such that a distance therebetween in the second direction is adjustable;
- a first support member attachable to and detachable from the first adjuster, the first support member comprising:
- a first support plate part having a first surface and a second surface opposite each other in the second direction, the first support plate part having a first support hole penetrating through the first support plate part in the second direction from the first surface to the second surface;
- a first protruding part protruding from the first surface and surrounding the first support hole, the first protruding part having a first outer diameter;
- and
- a second protruding part protruding from the second surface and surrounding the first support hole, the second protruding part having a second outer diameter greater than the first outer diameter, the first support member being attachable to the first adjuster such that either the first surface or the second surface of the first support plate part faces the second adjuster in the second direction;
- and
- a second support member attachable to and detachable from the second adjuster, the second support member comprising:
- a second support plate part having a first surface and a second surface opposite each other in the second direction, the second support plate part having a second support hole penetrating through the second support plate part in the second direction from the first surface of the second support plate part to the second surface of the second support plate part;
- a first protruding part protruding from the first surface of the second support plate part and surrounding the second support hole, the first protruding part of the second support member having the first outer diameter;
- and
- a second protruding part protruding from the second surface of the second support plate part and surrounding the second support hole, the second protruding part of the second support member having the second outer diameter, the second support member being attachable to the second adjuster such that either the first surface of the second support plate part or the second surface of the second support plate part faces the first adjuster in the second direction,
- wherein the first adjuster comprises a first hook extending toward the second adjuster in the second direction, the first hook extending through the first support hole and engaging with the first support plate part upon attachment of the first support member to the first adjuster,
- wherein the second adjuster comprises a second hook extending toward the first adjuster in the second direction, the second hook extending through the second support hole and engaging with the second support plate part upon attachment of the second support member to the second adjuster, and
- wherein,
- in a first state where the first support member and the second support member are attached to the first adjuster and the second adjuster respectively such that the first surface of the first support plate part and the first surface of the second support plate part oppose each other in the second direction,
- the first protruding part of the first support member and the first protruding part of the second support member are fitted in the first sleeve of the first roll when the first roll is accommodated in the accommodation space, and
- in a second state where the first support member and the second support member are attached to the first adjuster and the second adjuster respectively such that the second surface of the first support plate part and the second surface of the second support plate part oppose each other in the second direction,
- the second protruding part of the first support member and the second protruding part of the second support member are fitted in the second sleeve of the second roll when the second roll is accommodated in the accommodation space.
