Abstract:
1. A scanning device comprising: a substrate having a center space portion and a side space portion, the side space portion disposed at each side of the center space portion; a mirror unit disposed at the center space portion and having a support frame, the support frame coupled with the mirror unit in order to prevent dynamic deflection of the mirror unit and supporting the mirror unit; a pair of elastic rotation support elements disposed at each side space portion in order to support the mirror unit against the substrate and to be a rotating axis of the mirror unit; and a driving unit provided at the side space portion and driving the pair of elastic rotation support elements in order to rotate the mirror unit, wherein the driving unit comprises: a movable electrode extended from an end of the mirror unit which is adjacent to an elastic rotation support element and disposed at the side space portion; and a fixed electrode extended from a portion of the substrate and disposed at the side space portion in order to interwork with the movable electrode by electrostatic force.
