PURPOSE:To provide a rotary pattern variable display device capable of correctly detecting, stopping and displaying a pattern to be stopped according to direct detection and reading of an information code corresponding to a pattern. CONSTITUTION:A display plate 33 made of transparent resin is assembled to a display radioscopy unit 31 installed and set on the front side of a game board. A display window 34 for a stopped pattern for three frames each and a prize winning line L are formed on the front surface of the display plate 33. Pattern display units U are fixedly set longitudinally on the back of the game board corresponding to the respective display windows 34 of the display radioscopy unit 31. The pattern display unit U forms one unit by building a rotary drive control mechanism, a pattern belt and a detect and read means into a set frame. The pattern printed on the pattern belt is visually confirmed through the corresponding display window 34. Information codes corresponding to the respective patterns are formed on the pattern belt, and the codes are read and detected by an optical sensor. |
