PROBLEM TO BE SOLVED: To enable operating a masking member of a projector at the backside of a projector, and to enable adjusting light so as to practically irradiate only the object to be irradiated even during the daytime. SOLUTION: A front cover 54 with a front glass 6 is attached to the frontal side part of a lamp body part 53 of a projector body 52 detachably, and a back cover 55 equipped with a light source 7, an elliptic reflection mirror 8, and a spherical reflection mirror 9 are mounted on the back side of the lamp body part 53 opening and closing freely. An integrator 25 with a plurality of reflection plates at its inside is arranged at approximately middle part on the axis line inside the projector body 52, and in front of the integrator 25, a mask member comprising a ring panel 11 controlling the bound of the light irradiated to the object to be irradiated, an intermediate plate 65 with a window 69 to manipulate the mask members formed to the ring panel 11, mask members 70, 71 with handles 70A, 71A, and a masking means with a pressing plate 20 and a holding plate 22, is installed. An integration is aimed at by mounting a stabilizer box 84 at a concave part 83 formed on the projector body 52. |
