In order to improve mountability of a rolled sheet while preventing falling off of the rolled sheet, which makes a replacement operation easier, provided is a rolled sheet support mechanism ( 4 ) including: a pair of guide plates ( 20 ) opposed to side surfaces of a rolled sheet (P); a pair of support members ( 21 ) having, at ends thereof, insertion portions to be partially inserted into opening portions of a core tube ( 2 ) which are exposed to the side surfaces of the rolled sheet; a displacement member ( 22 ) displaced between an attachment position (S 1 ) and an accommodation position (S 2 ) while supporting the support members movably in a direction of an axis L of the core tube, with the support members being moved along the guide plates when receiving an external force; and a biasing member ( 23 ) for biasing the support member with an elastic force and pressing the insertion portion to the core tube in a state where the insertion portion is partially inserted into the opening portion to allow the rolled sheet to be pivotally supported, in which the pair of guide plates have a distance therebetween, which becomes smaller from the attachment position toward the accommodation position.
