A plurality of punches are divided into first group and second group. The cam mechanism provided between each punch of the first group and the driving means moves each punch by the motion operation of the driving means in a first direction, and the cam mechanism provided between each punch of the second group and the driving means moves each punch by the motion operation of the driving means in a second direction. Different pattern of punching is respectively possible by the first and second groups of punches.
