ABSTRACT:
A drive circuit is provided for selectively driving a driven element. The drive circuit includes a discharge section for discharging charges, which are accumulated in the driven element when the drive element is turned on, when the drive element is turned off. The drive circuit may include a drive element for driving the driven element. The drive element includes a first ground route disposed separately from a second ground route of the driven element. The first ground route is connected to the second ground route through a connection cable. A diode may be disposed between the connection cable and at least one of the first ground route and the second ground route.
