摘要： A stepping motor driving apparatus of an analog electronic clock, in which, when the rotation of a rotor is not detected after a pulse is supplied to a coil of a stepping motor, a first switching control section switches the pulse supplied to the coil to a pulse having a larger effective value, and when the rotation of the rotor is detected continuously for a predetermined period or a predetermined number of times, a second switching control section switches the pulse supplied to the coil to a pulse having a smaller effective value, wherein the apparatus further includes a third switching control section that switches a driving pulse to a pulse having a smaller effective value when the rotation of the rotor is not detected for two times continuously, even after the first switching section increases the effective value of the driving pulse for two times continuously.
