PURPOSE:To easily shape deformation of a roll body and perform stable supply of paper, by forming a roll body holder from an elastically deforming side plate and a part of the side plate to which external force is applied. CONSTITUTION:A holder 22 holdig a roll body 18a, on which belt-shaped paper 18 is wound in a roll state, is formed by elastic side plates 49 placed at a face- to-face position with a distance slightly larger than a width of the paper 18 of the roll body 18a. While cam surfaces 50, to the part of which external force is applied, are formed to the outside of said side plate 49. Then an arm 41 is turned at shaping of the body, and a roller 53 presses the cam surface 50 to forcibly contract the side plate 49 and shape the body 18a. |
