Abstract
It is an object to provide an optical component holding unit whereby the positioning accuracy can be improved while reducing cost through facilitated assembling and ensuring reproducibility. The fitting between a cross-sectionally noncircular-shaped rectangular convex portionand a rectangular hole and the fitting between a cross-sectionally circular-shaped circular convex portionand a circular hole, which surround or form opening portionsandfor allowing passage of light, guide adjacent optical component holding unitsto predetermined positions and couples the units detachably to each other for positioning in the three-dimensional direction, while the fitting between the rectangular convex portionand the rectangular hole and the fitting between spring pinsand fitting holes restrain the adjacent optical component holding unitsrelatively in the rotation direction for positioning in the rotation direction.
