Abstract
A remote control system for remotely switching an electric power supply to the display section of a display apparatus whose display data control section and display section are located far from each other and separately power-supplied from their respective local commercial power sources. This system fundamentally consists of three elements: an oscillator, a counter devised so as to output a switch opening signal after counting out a predetermined number of pulses outputted from the oscillator, and a relay switch inserted in the power supply line of the display section and to be made open by the switch opening signal from the counter. The counter is further supplied at its reset terminal with clock signals transmitted to the display section from the display data control section. Thus, while display data control section separately power-supplied continues to output said clock signals, the counter does not output the switch opening signal, leaving the relay switch kept closed. Only when the clock signals remain stopped for a predetermined period of time, the relay switch is made open to cut off the power supply to the display section.
