PROBLEM TO BE SOLVED: To minimize the moving quantity for positioning with a small number of sensors in the positioning of a sheet to improve the workability and stabilize the positioning precision. SOLUTION: For the center positioning of a photopolymer plate, a sensor having the smallest moving quantity for detecting a detecting angle part is selected from three preliminarily arranged sensors 158A, 158B, and 158D. Accordingly, the positioning work can be performed quickly, and the working efficiency can be improved.
