To send a larger amount of data by eliminating identification information of a telegraphic message which is a command transmitted by a game machine.
A main substrate comprises: a transmission timing generation part for alternately generating a signal indicating a first period of telegraphic message transmission permission and a signal indicating a second period of telegraphic message transmission non-permission; and a transmission part for transmitting the telegraphic message during the first period. A sub-substrate comprises: a receiving buffer check timing generation part for outputting the signals at receiving check intervals; a received telegraphic message number acquisition part for checking the number of telegraphic messages stored in a receiving buffer at the received check intervals; a received telegraphic message read-out part for reading out the telegraphic message when the telegraphic message is stored in the receiving buffer; a telegraphic message buffer for storing the telegraphic message read out by the received telegraphic message read-out part; and a command output part for outputting the telegraphic message which is stored in the telegraphic buffer when the telegraphic message is not stored in the receiving buffer.
