To suppress variation of a processed portion between objects upon processing even when the objects have indefinite shapes.

Shallot cutting processing system 10 has a conveyor 14, a robot 16, a three-dimensional sensor 18 for detecting a shallot 12, a camera 20 for detecting posture of the shallot 12, and a controller 28. The controller 28 has a first image processing unit 281 which sets an suction target portion of the shallot 12 based on the detection result of the three-dimensional sensor 18, a first controlling unit 2861 which controls the robot 16 so as to lift the shallot 12 by making a suction pad 166 contact the suction target portion of the shallot 12 and move the shallot to a predetermined position, a second image processing unit 283 which sets a processing target portion of the shallot 12 based on the detection result of the camera 20, and a second controlling unit 2862 which controls the robot 16 so as to lead the processing target portion of the shallot 12 to a position of a blade 2221 of a cutting device 22.
