PROBLEM TO BE SOLVED: To image an image of a dead angle region continuously to an image which is further easily visually confirmed by a viewer directly.SOLUTION: A dead angle auxiliary device 100 for imaging an image of a dead angle region which is blocked by an obstacle comprises a pair of mirrors 110 in which a semitransparent mirror 111 having a recessed-curved face shape semitransparent reflection face 111c which makes light indicating the image incident therein, is arranged at a viewer side, reflects a part of the light, and makes a part of the light permeate it, and a mirror 112 having a protrusively-curved face shape reflection face 112a which reflects the light to the semitransparent mirror 111 are arranged so as to oppose each other. The semitransparent reflection face 111c and the reflection face 112a are formed into cylindrical face shapes having prescribed curvature radii.SELECTED DRAWING: Figure 3
【課題】より容易に視認者が直接視認する像と連続して死角領域の像を映すことが可能となる。【解決手段】障害物によって遮られる死角領域の像を映す死角補助装置100であって、前記像を表す光を入射し、視認者側に設けられ光の一部を反射し一部を透過する凹曲面状の半透過反射面111cを有する半透過ミラー111と、光を半透過ミラー111へ反射する凸曲面状の反射面112aを有するミラー112とが互いに対向するように配置される一対のミラー110を備えてなる。半透過反射面111c及び反射面112aは、所定の曲率半径の円筒面状である。【選択図】図3
