An edge portion of a bound material is provided with first and second lines. The first and second lines are spaced at a small interval and arranged in parallel to each other. The first line is arranged outside of the second line of the bound material. A control unit controls first and second drive mechanisms in such a manner that the edge portion of the bound material is cut at the first line by a trim cutter, then the trim cutter or the table is moved at the small interval in a moving direction toward the second line, and then the edge portion of the bound material is cut at the second line by the trim cutter.
