<P>PROBLEM TO BE SOLVED: To accurately and efficiently drive an electric load having capacity components. <P>SOLUTION: The circuit includes a first power source part generating a voltage value before switching of applying to an electric lead, a second power source part generating a voltage value after switching, and an electric power accumulating part, then, the electric load is driven by switching a state from a state in which any one side of power source parts is connected to the electric load to a state in which the other power source part is connected. Then, when the power source part is switched, the state is switched from a state being connected to one side of the power source part through a state being connected to the electric power accumulating part to a state being connected to the other side of the power source part. Thereby, driving is performed efficiently by driving the electric load withdrawing electric power accumulated in capacity components of the electric load. Also, finally, since voltage from the first power source part or the second power source part is applied, driving is performed with the stable and accurate voltage value. <P>COPYRIGHT: (C)2010,JPO&INPIT |
