Abstract:
1. A motor drive control device for controlling a rotational speed of a motor, comprising: a motor driving section for rotationally driving the motor; a motor rotational speed detector for detecting a rotational speed of the motor; a driven member rotational position detector for detecting a rotational position of a driven member which is rotated by a rotational drive force applied by the motor; a correction amount calculating section for calculating a total correction amount, which is a sum of a correction amount calculated based on a rotational speed of the motor detected by the motor rotational speed detector and a correction amount calculated based on a rotational position of the driven member detected by the driven member rotational position detector; and a speed controller for generating a speed control signal corresponding to a total correction amount calculated by the correction amount calculating section, and outputting the generated speed control signal to the motor driving section.
