The pinion gear 110b is rotatably supported by the pinion gear 110b.

On the other hand, if the USB terminal can rotate at a predetermined angle with respect to the main body, the ease of engagement between the display portion and the main body can be improved.

Particularly, when the USB port formed on the display unit 10 is biased to either side, if the USB terminal 220 can rotate at a predetermined angle with respect to the main body 100, the user's convenience is increased.

The configuration of the present invention in which such a function can be implemented will now be described with reference to FIG.

6 is an exploded perspective view of a USB module according to an embodiment of the present invention.

As shown in the figure, the USB terminal 220 is provided on the USB terminal body 240, and a hinge groove 241 is formed on one side of the USB terminal body 240 in correspondence with the position of the hinge groove 241, The USB terminal 220 is connected to the USB socket 230 via the hinge protrusion 242 and the hinge groove 241 so as to be rotatable with respect to the USB socket 230. [

A cylindrical extension portion 244 is formed at the lower end of the USB terminal body 240. A hinge groove 241 having a predetermined length in a direction perpendicular to the drawing is provided at the center of the extension portion 244.

A hinge protrusion 242 coupled to the hinge groove 241 is formed at an upper end of the USB socket 230 on a pair of support plates 243 corresponding to the end surface of the extended portion 244.

With the above structure, the USB terminal 220 can be rotated at a predetermined angle with respect to the USB socket 230, thereby increasing the ease of engagement between the display unit 10 and the main body 100.

In addition, the locking protrusion 245 is provided on one side of the USB terminal body 240 so that the USB terminal 220 is fixed at 90 degrees with respect to the USB socket 230, and correspondingly, 246 are provided.

With this structure, when the USB terminal 220 forms an angle of 90 degrees with respect to the USB socket 230, the locking protrusion 245 is inserted and fixed in the locking hole 246.

3 to 5, it can be seen that a predetermined length of the moving pin is extended at one point of the sliding plate. When the sliding plate 130 is to be slid, the end of the moving pin 133 is held The user can move it.

When the camera itself is moved, contaminants including fingerprints may be attached to the camera lens, so that the structure of the moving pin 133 as described above is provided.

2, a camera 20 for photographing a user's iris, an infrared ray unit 50 inclined at a predetermined angle toward the iris, and an iris image photographed by the camera 20 are displayed in the main body 100 And a main board 40 provided with an ISP 30 for switching to a USB signal.

A general circuit pattern capable of transmitting an electrical signal is etched on the main board 40. The main board 40 is provided with a camera 20 for picking up irises and a camera 20 for eliminating the problem of glare caused by ambient light and the iris- An infrared ray portion 50 which is inclined at a predetermined angle to emit infrared ray IR is provided.

An ISP (Image Signal Processor) 30 connected to the camera 20 by an electrical signal to convert the iris image captured by the camera 20 into a USB signal is installed on one side of the main board 40 .

The USB signal converted by the ISP 30 is transmitted to the display unit 10 via the USB module 200. A flexible circuit board (FPCB) 60 is provided between the USB module 200 and the ISP 30, Or through a common electrical signal line.

The sliding plate 130 is electrically connected to the main board 40 by a flexible printed circuit board (FPCB) having a predetermined length. The flexible circuit board (FPCB) 60 is flexible, Even if the sliding plate 130 moves along the guide groove 110 and its position is changed, the iris image captured by the I camera 20 is stably stored in the main board 40 (30).

Referring again to FIG. 1, the iris recognition system using the iris recognizer described above is implemented.

First of all, a mobile phone having a display unit 10 in which an application for user's iris recognition is installed is provided. In the case of iris recognition for payment or security, it is necessary to execute an application installed in the mobile phone.

The iris display screen 400 on which the iris is displayed on the lower side is displayed on the display unit 10 at the time of executing the application and it is determined whether or not the iris of the user previously stored in the storage unit coincides with the imaged iris.

At this time, when the center line of the iris image transmitted from the main body 100 does not match the center line of the camera installed in the main body 100, the controller 300, which guides the user to the movement of the camera 20, Respectively.

That is, the control unit 300 continuously senses the center line of the camera 20 and senses whether or not the center line of the camera 20 coincides with the reference center line of the previously stored iris display screen 400, A movement direction alarm indication for guiding the movement direction of the movable body 20 is transmitted.

Movement direction alarm display can be implemented by various methods such as arrows, guidance messages, voice signals, and the like.

The user who recognizes the movement direction alarm display can slide the sliding plate 130 and perform the authentication procedure by correct iris recognition.
