PROBLEM TO BE SOLVED: To realize a game machine which can detect whether or not a control command submitted by a main CPU 112 is correctly received by a sub-CPU 212. SOLUTION: If the main CPU 112 judges a winning prize status, it transmits a control command commanding one winning-prize ball to be paid-out in the order of a signal-line L1→an input-output gate A→signal lines L5 and L6→an input gate B. Then, if the main CPU 112 transmits an interruption signal (INT), the sub-CPU 212 takes in the control command latched to the input gate B. The sub-CPU 212 outputs an acknowledgment signal confirming reception of the control command to the output gate C through a signal line L9. Then, the main CPU 112 sets a signal line L4 to an L level, and receives the acknowledgment signal latched to the output gate C in the order of the signal lines L7 and L5→the input-output gate A→the signal line L1.
