Abstract
A stepper motor controlling apparatus having a storing unit storing driving data for generating a stepper motor driving phase signal in each of plural controlling circuits, which share the driving data in the storing unit, thereby decreasing the total amount of the driving data. It is therefore possible to minimize the required capacity of the storing unit required for the driving data.
