Abstract

A positioning apparatus includes a moving member, an actuator, and a controller. The moving member can move in at least a first direction. The actuator is provided along the first direction. The controller controls a current applied to the actuator in order to support the weight of the moving member. The bending rigidity of the moving member in the first direction is greater than the bending rigidity of the moving member in a second direction perpendicular to the first direction.
