項に記載の情報表示装置。[Claims for Utility Model Registration] 1. A transparent plane-parallel plate having two planes that are parallel to each other, and a plane in which light is transmitted from one end of the plane-parallel plate into the plane parallel to the plane parallel to or almost parallel to the two planes parallel to each other. and an information display section that reflects the light incident on the parallel plane plate in an observable direction, the information display unit reflecting the light incident on the parallel plane plate from the light supply unit. At least a part of the other end where the light reaches is sloped so as to form an acute angle with either of the two parallel surfaces, and the light reaching the other end is totally reflected to form the parallel plane plate. An information display device characterized by emitting light to the outside. 2. Between the light supply section and the light incident end surface of the plane parallel plate, the light incident from the light supply section to the plane parallel plate is directed parallel or substantially parallel to two parallel surfaces of the plane parallel plate. The information display device according to claim 1, further comprising a diaphragm member that restricts only light. 3. The information display device according to claim 1, wherein the light incident end surface of the parallel plane plate is substantially a curved surface, and a lens section is configured to focus the light incident from the light supply section. 4. Claims 1 and 2 further comprising a light transmission means for causing the light incident from the light supply section and emitted from the other end of the plane parallel plate to enter the light supply section side of the plane parallel plate again. or any one of 3
The information display device described in Section.
