ABSTRACT:
If a velocity calculated by a velocity calculating unit deviates from a normal range, a target velocity is used as a feedback amount, an actuation amount corresponding to a deviation Ve=0 between the feedback amount Vf=Vt and the target velocity Vt is calculated, and a driving power corresponding to this actuation amount is supplied to a motor. A conveyor belt can be driven stably without causing irregularity in a speed of the conveyor belt.
