PURPOSE: A camera unit is provided to simplify the structure of driving units by minimizing the connection of the driving units to a control unit by utilizing control signals and to control the tilting operation of each driving unit, thereby enabling precise autofocusing control. CONSTITUTION: A camera unit includes a lens (10), a lens mounting stage, an actuator, at least two input/output terminals, and a control unit. The lens mounting stage supports the lens. The actuator is installed on an external housing unit and includes at least four driving units (30a, 30b) using an electrostatic force for moving the lens mounting stage. The input/output terminals supplies power and control signals to at least two among the driving units. The control unit applies AC power to the input/output terminals. |
