SOLUTION: In a performance expression part, a plurality of polarization films 11A and 11B by which a prescribed pattern looks as if it is floating by receiving light from a light source 12 are arranged in a series and the polarization films 11A and 11B are moved relatively to each other for making visual performance. It is desirable to provide this performance part at a display window 3 for displaying a part of plural patterns drawn on a rotation reel 2 or/and a front face panel part between the display window and a medal tray.
