    摘要： According to the present invention, a stepping motor driving apparatus having a rotor and a stator in n (an integer equal to or larger than 2) phases for moving a moving body is provided. The stepping motor driving apparatus includes a driver for selectively supplying to the stator a first current pattern for rotating the rotor at a first pitch and a second current pattern for rotating the rotor at a second pitch different from the first pitch based on a drive switching signal. The driver switches the first current pattern and the second current pattern at a point where a torque generated by the first current pattern is equal to a torque generated by the second current pattern and supplies the first current pattern or the second current pattern to the stator.
