Abstract

PURPOSE:To make full use of battery capacity and elongate the battery life by arranging a shunt circuit composed of two condensers and four switching elements and by supplying voltage to an electronic circuit. CONSTITUTION:When a signal C takes the 1st status of the level 1, transmission gates (TG) 11, 12 are conductive, TG 13, 14 are insulated and the voltage of a battery 2 is shunted on to condensers 15, 16. If the condensers are equal in capacity, half of the voltage of the battery 2 is charged to both ends of each condenser and the terminal voltage of the condenser 16 is supplied to an electronic circuit 4 and an oscillation frequency dividing circuit 3. When a signal d takes the 2nd status of the level 1, TG 11, 12 are insulated and TG 13, 14 are conductive and the voltage accumulated in the condenser 15 is supplied to the electronic circuit 4 and the oscillation frequency dividing circuit 3. And signals c, d are controlled by a timing circuit 17 in order not to take the state of the level 1 to each other.
