Abstract
A control circuit 200 for a carriage motor 60 has a speed differential generation circuit 206. The speed differential generation circuit sets a speed differential &Dgr;V at a constant value during a period P1, and the constant speed differential &Dgr;V is inputted to three operation elements 210, 212 and 214. Also, the speed differential generation element 206 uses the actual differential (Vt−Vc) as the speed differential &Dgr;V after the period P1.
