A multiple focal light beam generating device is provided with a multiple focal mirror device, to which a light beam is incident from a front side thereof. The device has a plurality of mirror surfaces arranged in serial to the incident light beam such that at least one mirror surface other than a mirror surface disposed farthest from the front side comprises a half mirror surface, for reflecting the incident light beam respectively at each of the mirror surfaces into directions different from each other as a plurality of partial light beams; and a light condensing device, to which the partial light beams are inputted from the multiple focal mirror device, for respectively condensing the partial light beams such that positions of maximally condensed points of the partial light beams are different from each other.
