The fingerprint sensor unit 110 can recognize the input direction of the fingerprint and the fingerprint of the user. The fingerprint sensor unit 110 may be formed of an optical type scanner using an optical lens such as a prism or a hologram and a non-optical type fingerprint sensor using a semiconductor device such as a CMOS device in order to recognize a user's fingerprint. An optical type scanner or a non-optical type fingerprint sensor can scan a fingerprint of a user to acquire an image of a predetermined type (fixed image, moving image). At this time, the image of the fingerprint acquired by the fingerprint sensor unit 110 may include a blank area in addition to the fingerprint area according to the contact state of the fingerprint. Specifically, for example, the fingerprint sensor unit 110 can be implemented as a slide type. The fingerprint sensor unit 110 senses fingerprints of a finger moving in a sliding manner, reads fragmentary fingerprint images, and performs fingerprint recognition in such a manner that the short fingerprint images are matched to one image to implement a complete fingerprint image . As described above, the fingerprint sensor unit 110 is not limited to the sensor unit of the specific type, but may be implemented by various types of sensor units.

For example, the control unit 150 can display the false unlock pattern information and the real unlock pattern information on the display unit 130 at the same time. Thus, the user can easily recall the real unlock pattern information set by the user from the false unlock information and the real unlock pattern information. In another example, the controller 150 displays the real unlocking pattern information on the display unit 130 in a preferred color set by the user, and the false unlocking pattern information indicates a color different from a preferred color set by the user On the display unit 130 as shown in FIG. Accordingly, the user can input a pattern based on his / her preferred color, thereby easily inputting a real confinement pattern.

The control unit 150 displays a registration fingerprint previously stored in the memory 120 on the display unit 130 in a case where the fingerprint of the user recognized through the fingerprint sensor unit 110 is matched with the registered fingerprint of the user stored in the memory 120. [ Can be displayed. The control unit 150 can change the locked state to the released state when a portion of the displayed registration fingerprint that matches the unlocking information is selected by the user.
