ABSTRACT:
A scanning apparatus (100) ensuring a smooth swinging movement of a deflector with a simple and compact structure includes a flat plate-like elastic member (11) having both end portions fixedly secured in a state in which an intermediate portion of the elastic member (11) is flexed arcuately, a deflector (12) fixedly secured onto the elastic member (11) at the intermediate portion thereof for changing a direction of a wave propagation coming from a predetermined direction, and a driving means (14) for reciprocatively rotating the deflector (12) by changing repetitionally magnitude of flexure of the elastic member (11) relative to the deflector (12) fixedly secured onto the elastic member (11).
