Inverting the operating insertion bracket (130); mounted on the insertion bracket (130), actuated to cause the identity card (10) to enter the insertion bracket (130) or exit from the insertion portion (111) a card entering and exiting drive unit (140); a photographing unit (150) mounted in the body (110) to capture an image of the identity card (10); and a multi-illumination unit (160) according to a deformation of the hologram image Projection angles are respectively mounted on both sides of the photographing portion (150), selectively projecting white light, infrared light, and ultraviolet light on the identity card (10); and a control portion (170) for actuating the flip driving portion (120), And the front and back images of the identity card (10) obtained from the photographing unit (150) and the stored micro-text and auxiliary maps Comparison to determine authenticity.

The authentication device for identity authentication used in various fields such as the administrative document issuing machine is generally the same as the "image scanner" of Patent Document 1 (Recommended Patent No. 10-0664394 of the Republic of Korea), and is used to receive identity in line units. The scan pattern of the image of the card.

These general scanning methods insert and withdraw the identity card in an institutional manner, which may cause problems when the identity card is transported to the inside of the authentication device due to the deformation of the identity card and the foreign matter on the surface. Therefore, a forced withdrawal device is often included.

Further, regarding the scanning speed, the scanning device (linear CCD and attached image sensor) is used, and it is necessary to maintain the scanning speed at a constant speed or lower when the precision of the scanning device is required.

Furthermore, if the insertion of the identity card is slightly enforced, an error may occur in the image data input by the scanning sensor, and therefore the guiding device is often installed in front of the proximity sensor.

Furthermore, in order to prevent the forgery of the identity card, a security hologram is often placed in a specific part of various identity cards, in order to prevent the color of the reflected image of the hologram image from being irradiated with light by other parts, and The color of the reflected image of the illuminating light of the specific portion where the holographic image is located overlaps, causing color damage of the holographic image and color sensing of the holographic image. It is necessary to illuminate a specific portion at a specific angle. However, it is difficult to perform light irradiation at a specific angle by scanning, and it is also difficult to perform light irradiation only to a specific portion.

On the other hand, in order to prevent the forgery of identity cards, micro-printing techniques are used to engrave characters of less than 1 mm, or micro-texts (and patterns) in which flat-panel texts are printed with patterns, most of which are printed. However, in the case of conventional scanning methods, The general resolution is around 600 dpi, and there is a problem that such micro-text (and patterns) cannot be recognized.

There are also images made with optical identification ink on the ID card, holographic images that appear or disappear according to the viewing angle, and patterns and photos printed with fluorescent ink that will illuminate under ultraviolet or white light (hereinafter referred to as It is an "auxiliary pattern"). However, the conventional invention has a problem that it is impossible to recognize that the holographic image has various appearances depending on the angle of illumination.
