ABSTRACT:
A movable body position control device includes a pair of position detectors configured to detect moving positions of both ends of a movable body; a pair of driving parts, the driving parts being configured to drive the both ends of the movable body based on a detection signal from the pair of the position detectors; a translation control part configured to make the driving parts can generate a driving force whereby a difference of translational action of the movable body can be prevented in a case where a moving speed of the movable body is changed due to a disturbance, and configured to control the driving parts so that detected positions of the position detectors can be consistent with each other; and a rotation control part configured to make the driving parts can generate the driving force whereby a rotational action of the movable body can be prevented in a case where the moving speed of the movable body is changed due to the disturbance and the movable body is displaced in a rotational direction, and configured to control the driving parts so that the moving body does not lean against a moving direction.
