PURPOSE:To improve the transmission density and to improve the transmission efficiency by allowing an interval timer of each data transmitter/receiver to synchronize at the reception of data of a specific data transmitter/receiver to avoid an idle period in the transmission timing between the data transmitter/ receiver. CONSTITUTION:When data transmission is started from the 1st data transmitter/ receiver N1, data is received by data transmitter/receiver N2-Nn. In the other data transmitters/receivers N2-Nn, when they receive the device number A of the said data transmitter/receiver N1, the timer is controlled by a control circuit provided to each. That is, when the number A is received, the interval timer in operation in the other data transmitters/receivers N2-Nn is reset once and the control circuit controls the timer to be set again forcibly. Then the interval times of the 1st data transmitter/receiver N1 and the other data transmitters/receivers N2-Nn are synchronized by controlling the interval times of the transmitters/receivers in the limp at a point of time t0 when the other data transmitters/receivers receive the number A. |
