ABSTRACT:
A camera includes a first lens unit on which a light beam is incident from a subject, a reflective mirror for reflecting the light beam through the first lens unit, in a direction substantially perpendicular to the optical axis of the first lens unit, a first diaphragm member arranged on a surface of a lens of the first lens unit closest to the reflective mirror with the surface of the lens facing the reflective mirror blocks unwanted rays of light other than the light beam that forms the image of the subject, a second lens unit on which the light beam reflected from the reflective mirror is incident, a second diaphragm member arranged between the first lens unit and the second lens unit blocks unwanted rays of light that travel outside the outermost periphery at which the light beam traveling from the first lens unit to the reflective member intersects the light beam traveling from the reflective mirror to the second lens unit, and an unwanted ray-of-light reflection prevention member arranged on the reflective mirror to prevent rays of light from being reflected from a region thereof other than the region thereof on which the light beam forming the subject image is incident.
