PROBLEM TO BE SOLVED: To doubly improve working efficiency and a model itself. SOLUTION: A cutter is constituted by furnishing a fixed board 13, a movable board 14 provided on the fixed board free to vertically move, a corrosion plate 9 arranged on the fixed board 13 and on which a sheet material 12 is placed, a roll feeder 16 to deliver this corrosion plate 9 from the upstream side of the movable board 14 to the downstream side and a control device 17 to actuate the movable board 14 and the roll feeder 16 in accordance with an input working program. The roll feeder 16 is devised to be connected to an NC servo motor and to be driven to reciprocally rotate. The control device 17 reverses the NC servo motor in accordance with the working program and to send the once pattern-drawn sheet member 12A upstream from the downstream of the movable board 14 as it is placed on the corrosion plate 9.
