A transmitting means that transmits continuous data made up of multiple consecutive times; and a normal status based on whether or not the continuous data transmitted from this transmitting means is received for the number of data constituting the continuous data at a certain time timing. A data communication device comprising: detection means for detecting a reception state; and reception control means for starting reception of actual data when the detection means detects a normal reception state.
