PROBLEM TO BE SOLVED: To speed up the communication processing between the circuits of a pachinko machine by quickly determining normal received data immune to effect of noises or the like from transmitted data. SOLUTION: Command data transmitted from a delivery control circuit 17 and a main control circuit 21 are sampled specified times (for example, 5 times) and the command data thus sampled undergoes a majority judgment to define the command data found the highest in majority as received command data. As a result, the normal data immune to effect of noises or the like can be defined as received command data when the frequency of sampling reaches a specified value thereby enabling the defining of the received command data as quickly as when no abnormal data is generated. This enables the speeding up of communication processing. If the defined received command data are not contained in the previously defined data, the received command data are discarded.
