PURPOSE:To simplify the transmission processing by adopting the constitution that a message data and a destination slave station code are sent from a slave station to a master station, the master station stores temporarily the received message data and sends it to a slave station in response to the given destination slave station code. CONSTITUTION:The destination slave station code as well as the message data is sent from the slave station to the master station, the master station stores temporarily the received message data and sends it to a slave station in response to the given destination slave station code. Then in sending once the data from the own slave station to the master station, the data is transferred and sent from the master station to the opposite slave station automatically, and even when the opposite slave station is at a location out side of the radio wave arrival range, it is not required to call the opposite party by the transmission processing many times from the own slave station, the ease of transmission processing is attained. Further, one transmission processing is enough for plural opposite stations.
