A drive controlling apparatus includes a driver configured to apply driving signals configured to excite a plurality of windings in a stepping motor, and a controller configured to acquire a detection result of excitation currents in the windings, and to provide a feedback control over the driving signals so that a difference can be reduced between a first time difference and a second time difference, the first time difference being a period from a first reference time set in an excitation current waveform of the winding corresponding to a first drive channel to a time at which a set current value is provided, and the second time difference being a period from a second reference time corresponding to the first reference time and set in the excitation current waveform of the winding corresponding to the second drive channel to a time at which the set current value is provided. |
