PROBLEM TO BE SOLVED: To provide a data communication system for a playing machine where communication of data with variable packet length is conducted without useless communication processing. SOLUTION: When a transmission section 1a transmits a transmission data signal of a packet and a synchronization clock signal in the data communication system for a playing machine, a reception section 2a reads the transmission data signal every time receiving the synchronization clock signal and recognizes end of the packet data communication when a succeeding synchronization clock signal cannot be received even when the elapsed time after the reception of the synchronization clock signal exceeds a prescribed time, then even when number of the transmission data signal sent from the transmission section 1a is not constant, the end of data communication of each packet can be recognized. |
