ABSTRACT:
An encoder produces a plurality of different phase signals. A detecting unit detects all edges of the plurality of different phase signals from the encoder. A central processing unit (CPU) measures edge intervals of edges succeeding with respect to time. A first process is for obtaining a control target value on the basis of a value measured by the CPU, and a second process is for controlling the drive speed of the drive source on the basis of the result of comparing the value measured by the CPU and the control target value.
