PROBLEM TO BE SOLVED: To provide a chance button providing a presentation effect in a game machine. SOLUTION: The chance button 1 includes: an assembly case 2 formed of a body portion 3, a bottom portion 4, and a lid portion 5; a frame 6 for holding a spherical chance ball 7 in the assembly case 2 so as to be rotated in any direction; pressure-sensitive conductive rubber 10 disposed at the bottom portion 4; an LED 18 for emitting incident light to light paths in the chance ball 7. The frame 6 is provided with driving mechanisms 50A, 50B, and 50C for rotationally driving the chance ball 7, and a circumferential movement-detecting portion 55 for detecting the amount or direction of vertical, horizontal, or rotational movement of the outer peripheral surface of the chance ball 7. The driving mechanisms 50A, 50B, and 50C rotationally drive the chance ball 7 to an optional position to provide presentation by the light paths. COPYRIGHT: (C)2010,JPO&INPIT
