Abstract
PURPOSE:To reduce the power consumption of a transmitting and receiving device, where a central operation device, a transmitting device, and a receiving device are connected through a data transmission line, by connecting a power on/off signal line between the central operation device and the transmitting device. CONSTITUTION:A central operation device 1 is connected to a transmitting device 2 and a receiving device 4 through a data transmission line 3 to transmit and receive data to and from the other-party device which is not shown in figure. A power on/off signal line 5 is connected between the central operation device 1 and the transmitting device 2; and if a power on signal is applied to the transmitting device through the signal line 5 simultaneously with or a little earliu than the output of a data signal from the central operation device 1 to a transmission line 3, the power switch of the transmitting device 2 is turned on, and data on the data transmission line 3 is supplied to the transmitting device and is transmitted to the other-party device. When a power off signal is transmitted from the central operation device 1 to the transmitting device 4 through the signal line 5 at the completion time of transmission of the data signal, the power switch is opened.
