Abstract
A stop range setting circuit sets a range of permissible positions around where the control object is desired to be stopped on the basis of a target position signal, and a potentio balance resistor (PBR) detects a present position of the control object driven by a motor. The comparison circuit compares the present position of the control object with the set range, and outputs an out-of-stop range signal and a rotating direction indication signal until the control object reaches the range. The out-of-stop range signal is input to a drive start determination circuit, and a drive permission signal is output to a drive circuit when the out-of-stop range signal is continuously output for at least a predetermined period of time. The drive circuit drives the motor in a direction indicated by the rotating direction indication signal while the drive permission signal is continuously output, so that an instantaneous ON/OFF signal is not input to the drive circuit in the presence of external noise.
