After the machine is powered on, insert coins to the coin acceptor, and then the counting signal is transmitted by the coin acceptor to the io board, and then the io board is transmitted to the counting kinescope, and finally the kinescope displays.
After inserting the coins, the coin acceptor sends a signal to the io board, and then transmits the signal to the relay through the io board, and the relay starts to supply power to the blower.
The blower is started, and then the air is exhausted through the small holes on the table. The wind of the blower reduces the friction between the pie and the table. Reducing the friction can make the pie moving faster, the running time is longer, and help the players to play the game with less strength.
