The prism reflector installed immediately above an indicator\s display surface consists of a prism and a flange portion that is flush with one surface of the prism and which extends from the periphery of that surface. The surface of the prism and the flange portion form a reflecting surface. A reflector plate is arranged to face the reflecting surface of the prism reflector and has a concave surface, whose light axis is inclined with respect to the reflecting surface of the prism reflector toward the thicker side of the prism. Light from the indicator\s display enters the prism, is refracted as it leaves the reflecting surface, and travels toward the reflector plate\s concave surface, which reflects the incident light back toward the reflecting surface of the prism reflector, which then reflects it toward the driver\s viewing point. Because the light travels back and forth between the reflecting surface and the reflector plate, a long light path is obtained for effective remote display while keeping the apparatus compact. The reflector plate\s concave surface enlarges the indicator display image, so that a large virtual image can be formed at a remote location from the driver.

An automotive reflection type display apparatus comprising: a reflecting member forming a reflecting surface, said reflecting member including a prism having first and second major surfaces adjoining at an acute angle and a flat plate-like flange portion on said prism, said flat plate-like portion being flush with said first major surface of the prism, said flat plate-like flange portion extending from a circumference of said first major surface; an indicator disposed to have a display surface facing said second major surface of the prism of the reflecting member that adjoins the first surface at said acute angle; and a reflector plate having a reflecting concave surface that opposes the reflecting surface of the reflecting member, said reflector plate being disposed in such a way that a light axis of the reflecting concave surface extending toward the reflecting surface of the reflecting member is inclined toward a thicker side of the prism and the reflector plate is disposed so that the display surface of the indicator is located within a focal point of the reflecting concave surface; wherein the reflecting member, the indicator and the reflector plate are arranged so that the light axis of the reflecting concave surface of the reflector plate extends optically through the reflecting surface of the reflecting member toward a driver\s seat, rays of light from a display of the indicator are transmitted through the prism of the reflecting member, reflected by the concave surface of the reflector plate back toward the reflecting surface of the reflecting member and then further reflected by the reflecting surface toward the driver\s seat so that a virtual image of the indicator display can be seen through and within the reflecting surface from the driver\s seat side.
