Zusammenfassung:Disclosed is a fingerprint input device using a portable terminal equipped with a camera, and an external optical device for inputting a fingerprint. According to the present invention, a fingerprint image may be generated by an optical fingerprint input method by using the external optical device of the present invention even when an existing portable terminal does not have a configuration for an optical fingerprint input. To this end, the external optical device is provided as an external type to be mounted in the existing portable terminal provided with a camera, and has an optical refractor and a mirror. The external optical device may generate a user's fingerprint image by an optical fingerprint input method, in accordance with circumstances, without interrupting the main use of a camera and an LED of the existing portable terminal.
