Abstract
A dichroic mirror for reflecting red light for optical separating and a dichroic mirror for reflecting red light for optical synthesizing are installed on the same plane in an image generating apparatus of the present invention. In addition, a dichroic mirror for reflecting blue light for optical separating and a dichroic mirror for reflecting blue light for optical synthesizing are installed on the same plane. Accordingly, a compact configuration can be realized. Since a main reflecting mirror is a rotating elliptic mirror and a lamp is located on a focus or around the focus, a lighting equipment which irradiates conic luminous flux can be realized.
