Abstract
In a remote control receiving system of an electronic apparatus such as a television receiver, a charger is connected to the output terminal of a sub regulator for driving a load such as a microcomputer by using an AC power source as an energy source, and a charging switch is connected between the load and the charger, and thereby the charging switch is controlled to turn on or off by a comparator on the basis of the charged voltage in the charger.
