PROBLEM TO BE SOLVED: To shoot game balls at shooting intervals shorter than usual at arbitrary timing without deteriorating the matching with the regulation of the number of balls shot per minute. SOLUTION: When a player presses a shooting interval changing button 80, a control signal changing means 506 transmits a control signal for shooting game balls at intervals shorter than usual to a shooting solenoid 61 so that game balls are shot from a shooting device at intervals shorter than usual. Accordingly, as game balls can be shot at intervals shorter than usual, a player can exhibit the player's skill and can secure the player's own profit. After game balls are shot at the shorter intervals for a prescribed period of time, a control signal for shooting game balls at intervals longer than usual is surely transmitted to the shooting solenoid 61, so that game balls are shot from the shooting device at intervals longer than usual, and the number of balls to be shot per minute does not exceed the regulation.
