PROBLEM TO BE SOLVED: To reduce the vibration of a rotor when held, to suppress the occurrence of noise, and to shorten the rising time of a motor, that is, to achieve the stable and quick rising of the motor. SOLUTION: This stepping motor driving method is for driving the motor by exciting each phase according to a driving signal output from a motor driving signal generating source including a motor driving IC. In a motor-starting control in which the motor starts rotation from a pull-in range of low-speed rotation in which self-starting is possible and the revolutions are gradually increased to rotate the motor in the pull-out range of targeted high-speed rotation, an excited state and a non-excited state are repeated initially for a fixed period of time, when the motor standing by in the non-excited state is excited upon the start of the driving.
