1. A lens positioning mechanism comprising:
a member holding unit that has a function of holding a second surface of a lens member having a first surface, which is a convex optical surface, and the second surface, which is an optical surface facing the first surface, and biasing the held lens member toward a side of the first surface; and
an attitude control unit that regulates edge positions of a plurality of portions on the first surface of the lens member biased by the member holding unit to position the lens member in a predetermined attitude,
wherein the attitude control unit is configured to regulate the edge positions by a tapered portion that extends in a biasing direction of the lens member, wherein the edge positions are configured to abut on the tapered portion.
