PROBLEM TO BE SOLVED: To make positioning easily when a polarizing plate is mounted on a set plate. SOLUTION: When a set plate 7 is turned to a given setting turned position, a stopper is fitted to a hindering plate 7 to limit the turn. A rotation arm 11 is stopped at the turned position. A rotation roller 10 stands by at a position lower than the set plate 7, while a positioning stopper 19 goes to a positioning place. In this state, a polarized plate 3 is fitted to a stopper 19 by push and mounted on the set plate 7. |
