Abstract
An optical axis of a telephotographic camera for picking up an enlarged image of an iris is placed between guide unit for guiding a subject K into a range in which an iris image can be picked up and direction indication guide unit for indicating the direction in which the subject K is to be directed. If the subject K wears glasses, the face direction of the subject K is changed as indicated by the direction indication guide unit so that an image of illumination light from an iris lighting fixture on the lens, etc., of the glasses of the subject K does not overlap the iris image.
