Abstract: A position adjusting unit according to some example embodiments includes a base; a mounting part, a driving unit, and a locking part on the base. The mounting part may be movably installed on the base and configured to have an optical element mounted thereto. The driving unit may include a plurality of actuators connected between the base and the mounting part. The driving unit may be configured to move the mounting part with respect to the base. The locking part may be configured to provide a fixing force for fixing a position of the mounting part. The locking part may be configured to release the fixing force when electricity is supplied to the locking part.
