射型テレビジヨン。[Claims for Utility Model Registration] (1) A projection television in which light emitted from a projection tube is reflected by a reflecting mirror to project an image on a screen, characterized in that a curvature is formed on the reflecting surface of the reflecting mirror. Projection type television. (2) The projection television set as claimed in claim 1, wherein the reflecting surface of the reflecting mirror is a curved surface having a single curvature and a convex curvature toward the cylindrical screen. (3) The projection television set as claimed in claim 1, wherein the reflecting surface of the reflecting mirror is a curved surface having a single curvature and a concave curvature toward the cylindrical screen. (4) The projection television set as claimed in claim 1, wherein the reflecting surface of the reflecting mirror is a curved surface having a single curvature and a curvature convex toward the spherical screen. (5) The projection television set as claimed in claim 1, wherein the reflecting surface of the reflecting mirror is a curved surface having a single curvature and a concave curvature toward the spherical screen. (6) The projection television set as claimed in claim 1, wherein the reflecting surface of the reflecting mirror is a curved surface with different curvatures in the vertical and horizontal directions. (7) The projection television set as claimed in claim 1, wherein the reflecting surface of the reflecting mirror is a curved surface with a compound curvature whose curvature changes depending on the location of the reflecting surface.
