PROBLEM TO BE SOLVED: To improve maintenance performance by easily and quickly performing the attaching/detaching work and adjusting work of a sheet-like member. SOLUTION: A sheet 80 is spread by having both end parts of an overlay sheet 80 supported by a shaft member, and photosensitive material 24 placed on a surface plate 18 and original film 60 superposed on it are covered by the sheet 80 so as to be closely vacuum-stuck in a color proof making device, so that exposure is performed. The one end part of the sheet 80 is folded and is made as the part to be supported 210 of an open sectional shape, and the part 210 is engaged with the peripheral surface of the shaft member 90 from the longitudinal and vertical direction of the shaft member 90 at inside. A holding member 212 is engaged with the shaft member 90 from the longitudinal and vertical directions of the sheet 80, and the folded back part of the part 210 is held between the holding member 212 and the shaft member 90, so that the folded back part of the part 210 is fixed at the peripheral surface of the shaft member 90. |
