Abstract:
1. An inertial drive actuator comprising: a fixing member; a displacement generating unit arranged on the fixing member and configured to generate small displacements in a first direction and a second direction opposing the first direction; a vibrating substrate configured to be reciprocally moved by the small displacements of the displacement generating unit and having a first electrode on a plane of the vibrating substrate and an insulating layer on the first electrode; a mobile object arranged on the plane of the vibrating substrate and having a second electrode on a plane facing the first electrode through the insulating layer; a frictional force control unit configured to control frictional force between the vibrating substrate and the mobile object such that a potential difference is applied across the first electrode and the second electrode to cause electrostatic adsorptive force to act; and a frictional force applying unit configured to frictionally couple the mobile object and the vibrating substrate to each other by magnetic adsorptive force.
