PROBLEM TO BE SOLVED: To prevent the invasion of a bar-like foreign body into a playboard by an unjust operation in the front side of a machine, and to suitably handle foul balls produced in a pachinko game. SOLUTION: In an auxiliary playboard(APB) 20, a receiving port 32 which can receive foul balls dropping in a foul ball port 31, and a ball recovery port 33 which can recover foul balls from this receiving port 32 and discharge them to the lower ball tray side are formed. On the front side of APB 20, a cover member 34 which can cover the receiving port 32 and the ball recovery port 33 is detachably installed. In addition, between APB 20 and the cover member 34, a guide/prevention wall 35 to guide balls and to prevent the invasion of a foreign body is formed. Thus, by the cover member 34 and the guide/ prevention wall 35, the unjust invasion of a foreign body into the playboard from the front surface of APB 20 is prevented, while foul balls entering the receiving port 32 are guided for the ball recovery port 33.
