Abstract:
1. An electrostatic attraction driving apparatus, comprising: a stator disposed to extend in a moving direction; a mover facing the stator; stator-side electrodes protruding from a facing surface on the stator facing the mover perpendicularly to a direction of the mover and at the same time aligned along the moving direction, and mover-side electrodes provided on the mover and protruding from a facing surface on the mover facing the facing surface on the stator perpendicularly to a direction of the stator and at the same time aligned along the moving direction, wherein the stator-side electrodes and the mover-side electrodes are disposed facing each other in a width direction which is perpendicular to the moving direction and also perpendicular to a direction in which the facing surface on the stator faces the facing surface on the mover, and the mover is moved in the moving direction by electrostatic attraction force generated at portions where the electrodes on the stator and the mover-side electrodes are disposed so as to face each other, and wherein a plurality of the electrodes on the stator is disposed on the facing surface on the stator at predetermined intervals in the moving direction and in the width direction in a regular manner, and a plurality of the mover-side electrodes is disposed on the facing surface on the mover at locations where the mover-side electrodes do not overlap with the electrodes on the stator in a regular manner.
