PROBLEM TO BE SOLVED: To provide a game machine in which a main board and a put-out control board perform bi-directional serial communication, capable of preventing missing of the receipt of commands without considering output timings of commands.SOLUTION: A micro computer 560 for game control and a micro computer 370 for put-out control transmit and receive control commands by serial communication. The micro computer 560 for game control transmits a connection checking command to the micro computer 370 for put-out control for every time of lapse of a prescribed period. The micro computer 370 for put-out control transmits a connection OK command to the micro computer 560 for game control based on reception of the connection checking command. At this time, the micro computer 370 for put-out control transmits the connection OK command in a mode in which the micro computer 560 for game control can recognize a control state.SELECTED DRAWING: Figure 27 |
