PROBLEM TO BE SOLVED: To provide a game machine enabling a suppression of a cost rise to meet a demand required in a structure to realize a rotation presentation of a rotation body.SOLUTION: A Geneva mechanism 90 provided in an upper presentation part is configured by including a driving wheel 91 continuously driven by driving force and a driven wheel 92 engaging with the driving wheel 91 and rotates intermittently. That is, the driving wheel 91 has a pin member 93 formed on a peripheral surface. The driven wheel 92 has U shaped concavities 96, 98 that can accept the pin member 93. When the driving wheel 91 is driven to rotate, the pin 93 enters the concavities 96, 98, which intermittently drives the driven wheel 92. Also, in the driven wheel 92, a groove 90a to specify its own position is formed separately from the U shaped concavities 96, 98.SELECTED DRAWING: Figure 36 |
