PURPOSE:To lead smoothly the tip of a film by providing an elastically deformable film guide member between a guide wall and a film holding member. CONSTITUTION:A film guide member 4 consisting of a resin and a metallic sheet is provided on a guide wall 2 so that the inside surface is extended in the direction of a holding roller 3b of a film holding member 3. As a result, the tip of a film is led so as to go over the cut end part of the guide wall 2 by the film guide member 4, and supposing that a fact that the tip of the film follows a curvature and does not advance smoothly occurs, the tip of the film applies a pressing force to a part overhanging from the guide wall 2, an overhang part of the film guide member 4 is elastically deformed and escapes, a resistance to an advance of the film is reduced, and a smooth advance is recovered. |
