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 |
