PROBLEM TO BE SOLVED: To reduce a number of sensors by arranging a sensor unit, which detects a deceleration position and a top position of a work, to a carrying out table arranged at the side of a bending machine free to position and corresponding to a length of the work. SOLUTION: A carriage 9 is connected to a chain 12 which winds around a drive pulley 13 connected to a motor M2 and a driven pulley 14 connected to an encoder E2, a sensor unit 8 consisting of a deceleration sensor 8A and a stop sensor 8B is mounted. By driving the motor M2 through NC16 and feedbacking the signal from the encoder E2, the sensor unit 8 is precisely positioned corresponding to a length L of a work W. When a work W is moved, the tip of the work W shuts off a light of the deceleration sensor 8A, the deceleration sensor 8A is made ON to decelerate the work W, when a light of the stop sensor 8B is shut off, the stop sensor 8B is made ON, the work W is carried out and is stopped at the center part C of the table 1.
