Abstract:
A first holding member holds a first optical system and a first mirror, and has a first junction surface. A second holding member holds a second optical system and a second mirror, and has a second junction surface. A junction portion is configured such that, in a state where the first junction surface and the second junction surface are aligned with each other, the second holding member is capable of being shifted in a direction of both the junction surfaces and rotated around an optical axis, and makes it possible to perform optical axis alignment. An emission-side optical axis of the first optical system and an incidence-side optical axis of the second optical system are aligned with each other, and thus a U-shaped optical path is formed by the first and second optical systems.

Claim (Index 11):
A projection lens comprising:\n at least one incident lens; at least one intermediate lens; a first optical axis bending member disposed between the incident lens and the intermediate lens, in an optical path; at least one emission lens that projects light from the incident lens and the intermediate lens; a second optical axis bending member disposed between the intermediate lens and the emission lens, in an optical path; a first frame that holds at least the incident lens; a second frame that holds at least the emission lens, and a third frame that holds at least the intermediate lens, wherein the first optical axis bending member bends an optical axis of the projection lens, the second optical axis bending member bends the optical axis, the first optical axis bending member and the second optical axis bending member form a substantially U-shaped optical path, and the projection lens is a combination of at least the first frame, the second frame, and the third frame.
