ABSTRACT:
A projector including a shiftable projection lens unit is disclosed. The projector includes an illumination unit adapted to emit generated light, a micro device adapted to receive the light from the illumination unit, and to produce an image using the received light, a projection lens unit adapted to emit the image produced by the micro device, a reflector arranged at a downstream end of the projection lens unit, and adapted to change a direction of the light incident from the projection lens unit on the reflector such that the image is externally emitted, and a driving unit adapted to shift the projection lens unit and the reflector, thereby adjusting an emission direction of the externally-emitted image.
