An automatic focusing projector has a reflector which includes a semispherical mirror and a semielliptical mirror in combination, and a contrast chart having a contrast pattern associated with the reflector. The first focal point of the semielliptical mirror is identical to the center of the semispherical mirror. The contrast pattern is located between the first and second focal points of the semielliptical mirror. A light source is provided in the vicinity of the first focal point of the semielliptical mirror. The light source can be a white light source, and a colored filter can be positioned forwardly of a projecting lens which forms part of the projector in order to pass light having a wavelength region of low luminosity in which a human eye is virtually insensitive.
