Abstract

PURPOSE:To save electric power, by providing a terminal controller with a means for discriminating the in-use conditions of plural terminals and powering off the terminal controller when all terminal equipments are not used. CONSTITUTION:An operator turns on a switch 8 to supply electric power from an outlet 7 to the power supply circuit 16 of the terminal controller, supplying a voltage to be supplied to a load to a terminal 17. Then when one of plural terminal equipments is are not shown in a figure is powered on, that is detected by a detector 18 to generate a pulse at a terminal 13, and an FF12 turns on a transistor TR11 to energize a relay 10, closing a switch 9. Even after the operator opens the switch 8, the switch 9 is closed if even one of the terminal equipments is in operation. When all the terminal equipments are not used, the detector 18 outputs a pulse 14 to invert the state of the FF12, which turns off the TR11 to release the relay 10, opening the switch 9. Consequently, the power source is turned off automatically to save electric power.
