<P>PROBLEM TO BE SOLVED: To prevent errors in managing the number of prize balls in a main control board and a prize ball control board. Ž<P>SOLUTION: When the power supply is recovered, the value in a stack buffer evacuated when power outage is set at a stack pointer to return the state of a program to the state before the power outage (a step S52). A delay time processing is executed for the delay of the starting time of a CPU 66 of a put-out control board 31 (a step S53), and the state of an output port is recovered (a step S54). Respective registers evacuated when power outage are recovered (a step S55), and normal-time processing is executed (a step S56). When the power supply is recovered, a program for the main control board 30 is actuated about 20 ms later than the program for the put-out control board 31, so that the put-out control board 31 executes the delay time processing for the period of 20 ms to eliminate errors in put-out balls as prize balls. When a command to start the normal control is received from the main control board 30, the delay time processing is terminated, and the put-out control board 31 initiates the control of a ball run-out motor 31c.
