PROBLEM TO BE SOLVED: To simplify the arrangement of a pachinko game machine. SOLUTION: A full switch 43, a supply switch 44, a prize-ball dispensing switch 51, an optional winning hole switch 52, and a reset switch 53 are connected to the input side of a prize-ball control board 31, and a first-grade starting hole switch 36a and a count switch 40b are also connected to the input side via a main control board 30, as shown in Figure. 5. A ball cutoff motor 54 and an error indicating LED (7-segment LED) are connected to the output side of the prize-ball control board to form a one-way communication circuit capable of signaling only the prize-ball control board 31 from the main control board 30. The prize-ball control board 31 is backed up so that data about the number of prize balls yet to be dispensed, which is increased upon the entrance of balls into starting holes and decreased upon the dispensing of prize balls, will not be erased during power outages. The full switch 43 and the supply switch 44 are directly connected to the prize-ball control board 31. The prize-ball control board 31 stops the drive of the ball cutoff motor 54 when the full switch 43 detects that the pachinko machine is full of balls.
