A driving apparatus of a stepping motor has a simplified circuit structure and a bipolar driving system. The stepping motor has two exciting coils, which are driven by respective bridge circuits. Transistors provided respectively on two sides of one of the bridge circuits are commonly used by both of the bridge circuits. Accordingly, the driving circuit is formed with a reduced number of transistors.
