Abstract

PURPOSE:To accurately shift readily a movable element by temporarily stopping in 2-phase excitation when stopping to one-shape excitation position, and then shifting one step. CONSTITUTION:A step motor 5 for a carriage is connected through a motor drive circuit 6 to a CPU3. Further, a position detector 7 connected to a CPU3 is mounted at the motor 5. Since a movable element can be stopped at the position of one-phase excitation position and of two-phase excitation position, the minimum shifting distance can be shortened. Further, to prevent a damping from occurring in case that it is stopped at the weak one-phase excitation position of the exciting force, it is temporarily stoppat the the two-phase excitation position of the exciting force before one, and it is then shifted by one step to accurately stop at the original object position.
