The present invention relates to an iris scanning device. The iris scanning device according to an embodiment of the present invention comprises: an incidence surface in which an iris image enters; a first reflecting surface which is connected to the incidence surface and arranged while facing the incidence surface; a second reflecting surface which is connected to the incidence surface and arranged while facing the first reflecting surface; lenses which are connected to the first and second reflecting surfaces and are arranged in opposite to the second reflecting surface; an image sensor which obtains an iris image screened from the screening surface of the lenses; a cover which houses the lenses and an image sensor inside and forms an opening that exposes the incidence surface of the lenses to the outside; a base to one side of which the cover is attached; an IR sensor which is provided in a base adjacent to the cover; and an IR LED provided in a base adjacent to the cover. Accordingly, four surfaces have unified lenses, and thus an optical route can be shortened, thus allowing miniaturization and lightness. Moreover, an iris recognition distance can be improved to 20-30 cm, and thus an error rate can be reduced efficiently. |
