Abstract
A cut sheet is forcibly humidified. A cut sheet S travels upward between a pair of guide plates 65 and 66 facing each other. The guide plates 65 and 66 are respectively formed with openings 67 and 68 across which linear bodies 69 and 70 are stretched. A sprinkler 30 sprinkles water droplets toward the opening 67 to supply moisture to the cut sheet S traveling between the guide plates 65 and 66.
