<p>PROBLEM TO BE SOLVED: To prevent a wrinkle from developing on an end face of a film roll by preventing a resistance to gravity from a floor face from working on the film part of a film roll in a wrinkle countermeasure structure for a film roll, where a film roll is constituted by winding a film around a core member serving as a taking-up core, with the end face of the film roll covered by a flat protection plate that prevents external force from being applied on both end faces.SOLUTION: A core member 11 consists of a hollow pipe and keeps the end face of a film roll 10 covered by a protection plate 21 in a condition that a cap 22 penetrating the protection plate 21 is inserted into the hollow part of the core member 11. A part sandwiched by the core member 11 and the protection plate 21 in the periphery of the cap 22 is provided with a spacer 23 having a strength to bear the gravity of the film roll 10. When placed in a condition that the film roll 10 develops a resistance to gravity, the core member 11 gets the resistance transmitted from the protection plate 21 via the spacer 23.</p> |
