A mobile telephone ( 1 ), when being folded, is set in a lock state by an opening/closing detection and lock mechanism ( 50 ), and then a control circuit ( 30 ) stops supply of an electric power to a fingerprint authentication unit ( 60 ). In this state, upon detection of an incoming call from an external apparatus, the control circuit ( 30 ) restarts the supply of the electric power to the fingerprint authentication unit ( 60 ), and when a user is authenticated as a legitimate user by the fingerprint authentication unit ( 60 ), instructs the opening/closing detection and lock mechanism ( 50 ) to carry out an unlocking operation. |
