Abstract
While both a forehead and a cheek are made in close contact to an eye position fixing portion, a space defined between a left eye and a pinhole is shielded from extraneous light. When light derived from a room lighting device is entered into a right eye, a diameter of a pupil of the left eye is defined in a self-definition manner due to an interlocking characteristic of a living body, and then, a width of an irismay be secured under stable condition. While infrared light is illuminated from a button lighting device onto this left eye, this illuminated left eye is photographed by an image pick up unit, and then, feature information as to the photographed left eye is compared with registered feature information in an individual identifying unit so as to execute an individual identification operation.
