ABSTRACT:
An actuator apparatus for applying an electrical signal to an electro-mechanical energy conversion element to form a vibration, and for driving a moving body based on the vibration.
When the moving speed of a moving body moved by the actuator apparatus is monitored by, e.g., an encoder, the apparatus detects the encoder output at a timing corresponding to the vibrating state of the actuator, so that an encoder output free from the influence of the vibration can be precisely detected.
