Abstract
A conveyance device () comprises: a base member (); a holding member () that moves along the base member (); a motor (M) for advancing and retracting the holding member (); a target (T) provided on the holding member (); an optical distance sensor () positioned so as to face the target (T) when the holding member () is in the advanced position; and a control device (). A processor () is configured such that: a basic rotation speed is applied to the motor (M) to advance the holding member (); the actual distance from the optical distance sensor () to the advanced target (T) is measured by the optical distance sensor (); a corrected distance for moving the holding member () to the advanced position is calculated on the basis of the measured actual distance; and the motor (M) moves the holding member () on the basis of the calculated corrected distance.
