PROBLEM TO BE SOLVED: To smoothly and stably rotate or stop a pattern drum, maintain the accurate detection stop display of a pattern, and deploy a proper pattern combination game. SOLUTION: A pulse drive-controlled stepping motor 47, a pattern position detecting photoelectric detector 50, and a pattern illuminating lighting means 51 are arranged at the required positions and connected to a drive control circuit respectively on a drive board 46 capable of being connected to an electronic control device, a pattern drum 54 arranged with various patterns for win and miss on the outer periphery is connected to the stepping motor 47, and a pattern unit 45 is constituted in a set unit. The pattern drum 54 is integrally provided with a disk-like cover section 56 having a boss section 57 in a rim section 55 formed into a ring shape on the outer periphery, and a pattern reference mark index 58 detected by the detector 50 is formed at the prescribed position of the rim section 55. |
