PROBLEM TO BE SOLVED: To provide a sheet folding device capable of realizing automation of multiple-folding. SOLUTION: A sheet feeder 10 feeds a sheet 3 one by one. A creasing device 20 includes first and second rolls 22, 23. The first and second rolls 22, 23 have pressing molds on the peripheral faces of cylindrical base bodies, rotate in synchronization with each other, sandwich and press the sheet 3 from both face sides to impart a crease to the sheet 3, and send the sheet 3. A folding device 30 receives the sheet 3 sent from the creasing device 20, folds the sheet 3 along the crease and sends the sheet 3. A folding-up device 40 folds up the sheet 3 sent from the folding device 30 along the crease into a flat state. The sheet feeder 10, the creasing device 20, the folding device 30, and the folding-up device 40 are provided in a series of carrying path. COPYRIGHT: (C)2004,JPO
