摘要：
The present invention relates to an optical beam detection device for detecting deviation in the optical axis of light beams from a reference optical axis, the optical beam detection device provided with a converging member for converging the light beams; a light receiving surface that is disposed near the position where light beams that have an optical axis that coincides with the reference optical axis are converged by the converging member; an optical path deflector for deflecting light beams that have an optical axis that deviates from the reference optical axis, after they have passed through the converging member; and a light detecting element for detecting the light beams that have been deflected by the optical path deflector.
