PROBLEM TO BE SOLVED: To prevent the provision of the games without the connection to a card processing device and moreover, reduce the number of signal lines for the transmission or reception of the signals pertaining to the ball dispensing control while accomplishing the accurate dispensation of the balls. SOLUTION: A ball dispensing request signal, a ball dispensing preparation signal, a ball dispensing command signal and a ball dispensing completion signal are transmitted or received between the pachinko game machine involved and the card processing device to dispense the balls. The pachinko game machine has a wire joint which is used in common to connect both of a wire for a balance display means and a wire for inputting the connection signal that disables the operations with no input from the card processing device to the card processing device. It also has a photocoupler for transmitting the ball dispensing preparation signal and the ball dispensing completion signal with one signal line and another photocoupler for receiving the ball dispensing request signal and the ball dispensing command signal with one signal line.
