PROBLEM TO BE SOLVED: To provide a checkup device for a precut work material by which it is checked whether the precut work material is individually processed with accuracy. SOLUTION: A carrying-in side carrying conveyor 10 and a sending side carrying conveyor 11 are mounted leaving an appropriate space 12 in between and a frame 13 set behind the appropriate space 12 and further the tip of an arm member 13 protruding from the top of the frame 13 is protruded ahead from the carrying conveyors 10, 11. Further a first laser generator 15 is mounted on the tip of the arm member 13 and a laser beam is set so that it is emitted through a specified position. A rail is laid on the side part of the carrying conveyor 11 and a positioning device is mounted so that the carrying conveyor 11 is moved along the rail. A first stopper 18 projecting over a long distance above the carrying conveyor 11 is fitted to the positioning device with the rotating arm member 13 and a short second stopper 20 is fitted, behind the first stopper 18, in a freely rotatable manner by the arm member 13. The tip 18a of the first stopper 18 is movable at a specified position.
