<p>PROBLEM TO BE SOLVED: To provide a game machine that can suppress an occurrence of a game ball jamming in a ball entry device.SOLUTION: In a Pachinko game machine, in a jackpot game state, an opening/closing member at an attacker unit (a small door unit on the game board) opens to allow the entry of game balls into a jackpot winning port. Also, when the opening/closing member is closed, the game balls can pass between the opening/closing member and the glass pane. However, at the time when the opening/closing member opens, a game ball jamming may occur by the game balls' being sandwiched between the opening/closing member and the glass pane. When a game ball jamming happens, the game ball jamming can be solved by slightly closing the opening/closing member.</p> |
