Abstract: Disposed in front of the lastly stopping center reel 12B of three reels 12A, 12B, and 12C is a cover member 16 which is movable between the position of a display apparatus 108a and a shelter position thereabove and is formed with a picture Fo. When the reel 12B is stopped with its picture Fo placed at the display window 108a, in the case where each of the other two reels 12A and 12C is stopped with the picture Fo placed at the display window 108a (in the case of a jackpot), the cover member 16 is moved from the shelter position to the position of the display window 108a and minutely vibrates at the position of the display window 108a before being stopped, whereby the picture Fo' formed in the cover member 16 appears in an unusual mode. Accordingly, the player's impression when winning a jackpot in a game machine equipped with thus configured reel apparatus can be fully enhanced, thus allowing enjoyability thereof to improve.
