ABSTRACT:
An actuator includes an apex section which can make a contact with a paper, a thin plate which has two inclined sections each extending from the apex section, a piezoelectric layer which is arranged on each of the inclined sections, and an individual electrode which is provided to each of the piezoelectric layers. The piezoelectric layer between the individual electrode and the inclined section is deformed by being applied with a voltage selectively to the two individual electrodes by a driving circuit. By deforming the piezoelectric layer, the apex section can be displaced and thus the paper can be transported. A movable apparatus which is supported on the floor by the apex section is also provided. A micro device in which an element is provided to the apex section is also provided.
