英文摘要	In the light-source position adjustment device, a magnification lens 31 magnifies a light bundle emitted from a light source 50. A half mirror 32 guides the light bundle outputted from the magnification lens system toward the first and second optical paths. An angular shift measuring portion is disposed in the first optical path for detecting emission angle intensity distribution of the light source. A position shift measuring portion is disposed in the second optical path for detecting a magnification image of the light source which is produced on an image plane of the magnification lens. The light source 50 is disposed on a multi-axes stage unit 10 which is driven by a stage drive unit 20. A control portion 40 receives output signals from the angular shift measuring portion and the position shift measuring portion, and determines an amount by which a light-emission direction shifts from the predetermined standard direction and an amount by which a light-generating point of the light source is displaced from the standard position. The control portion 40 outputs control signals to the stage drive unit. Receiving the control signals, the stage drive unit 20 drives the multi-axes state unit 10 so that the light-emission direction be aligned with the standard direction and so that the light-generating point be located on the standard position.
