ABSTRACT:
A guide beam direction setting apparatus of the present invention has a guide beam generator (12) having a guide-beam emission optical system (14) for emitting a guide beam (P), an indicator-beam emission optical system (15) for emitting an indicator beam (K), and detection units (23) for detecting the indicator beam. The indicator beam (K) is a beam which has a flat spatial spread in the emission direction of the guide beam. The detection units (23) are disposed so that they correspond to the collimation direction (L) of a collimation direction unit (11) and that they are spaced from the indicator-beam emission optical system (15), and the emission direction of the guide beam (P) is aligned with the collimation direction (L) by detecting the indicator beam (K) with the detection units (23).
