Abstract
A lens mirror array includes a plurality of transparent optical elements integrally connected to each other in one direction. Each of the optical elements includes: an incidence side lens surface on which light is incident; an exit side lens surface through which incident light exits; and a flange portion having a surface continuous to the incidence side lens surface. The surface of the flange portion is arranged at an angle at which unnecessary light incident on the flange portion is guided to a position deviating from an slit, the slit allowing transmission of effective light in light that exits through the exit side lens surface.
