Abstract
PURPOSE: To permit a roll sheet to be stably supplied with such a construction as to apply torque of a back tension generating member to a roll sheet by urging an engagement plate provided in a reel hub against the inner surface of a core of the roll sheet.
CONSTITUTION: In this roll sheet holding system, torque generated in a back tension generating member 17 is transmitted to a reel hub 4, and an edge portion 12 of an engagement member 7 is wedged into a paper tube to apply back tension to the entire roll sheet 1 through the paper tube 2. Thus, steady running of the sheet can be obtained without any irrational force acting on the roll sheet 1 but with uniform back tension applied over the entire width of the sheet. When it is required to rewind the roll sheet 1 from some or other reasion, the roll sheet 1 is manually rotated in the direction of arrow C. As a result, the wedging of the edge portion 12 into the paper tube 2 is released, so that a pivotable lever 6 receives the rotational force in the direction of arrow D from the paper tube 2 against the tensile force of a spring 13. In this way, the roll sheet 1 can be freely rotated and rewound.
