PROBLEM TO BE SOLVED: To provide an imaging device which is structured simply and never gives excessive psychological burdens on a subject. SOLUTION: A reflected image of infrared light from an eyeball 10 of a subject is inputted in the imaging part of this device. A cold mirror 20, which transmits infrared light but reflects visible light, is attached to the front surface of a lens 19. So the cold mirror 20 transmits the reflected infrared light to the eyeball 10, but reflects the reflected visible light to the subject. In determining the imaging position, the subject can confirm that the position is correctly set when the subject looks at his/her own eyeball 10 reflected in the cold mirror 20 wholly without being eclipsed. |
