ABSTRACT:
A stepping motor control system for a recording apparatus which uses a stepping motor as a driving source of a carriage with a recording head, has a stepping motor driving circuit for exciting the phases of the stepping motor, and a control circuit for transferring data corresponding to a predetermined stepping motor driving curve to the driving circuit, so as to easily obtain a stepping motor driving curve that can suppress vibrations, and the driving curve is formed from an Nth-order specific formula having two or more inflection points.
