Abstract
PURPOSE: To save energy not only when a signal is received normally but also when the signal is received abnormally by supplying power to a code identification circuit only when the signal is received by dividing into a low power consumption circuit and the code identification circuit that consumes much power. CONSTITUTION: A drive control circuit is composed of a low power consumption circuit 10 and a code identification circuit 20 where power is constantly supplied. Then, when a reception signal (a) is not inputted, a selection switch 21 stays open since no identification code is included in output (b) and no power is supplied to the identification circuit 20. On the other hand, when the reception signal (a) is inputted, the switch 21 is closed since a code pattern is included, power is supplied to the identification circuit 20, and the supply is retained. Also, when a signal that is not intended such as noise and incidence light is inputted, timer output (d) opens or closes the switch 21 via an AND circuit 22 and supplies power to the identification circuit 20 intermittently.
