PROBLEM TO BE SOLVED: To provide a roll position confirming device with a simple method at a low cost. SOLUTION: A pallet placement base with a turning function is provided at the predetermined position, in which a pallet loaded with stacked rolls is to be carried, and a rail is provided over the pallet placement base, and the rail is loaded with a slider capable of measuring movement distance from a reference position, freely to be slid. A laser device for generating the visible light laser line is fitted to the slider, and a computing device geometrically obtains the center position of each stacked roll on the basis of the movement distance of the slider, a diameter of the rolls, and a loading pattern of the rolls. |
