PROBLEM TO BE SOLVED: To prevent generation of defective carriage or defective matching even when punching burrs are generated in the vicinity of punched holes by arranging a sheet carrying means comprising a first body of revolution and a second body of revolution to press the sheet against the first body of revolution on the downstream side in the carrying direction of a puncher, and the passing position of the hole to be punched by the puncher. SOLUTION: Press roller pairs 7 comprise a press roller 7a as a first body of revolution, and an energizing roller 7b as a second body of revolution to energize the press roller 7a by a leaf spring 7c, and are provided on the downstream side of a puncher 5 to hold and carry the punched sheet. The nip width of the press roller 7a and the energizing roller 7b provided at the position corresponding to two sets of punches 17a and dies 17b on a press roller shaft 7d is formed sufficiently larger than the diameter of a punched hole by the puncher 5 so that the punch hole may pass the nip of the press roller pairs 7 even for the transverse deviation or meandering of the sheet. |
