PURPOSE:To effectively relieve a user from forgetting the registered identification word and to attain the use of an equipment by providing a means which shows plural identification words including the one registered previously by the user to the user. CONSTITUTION:An insignificant word generating part 7 produces plural insignificant words similar to a registered identification word, for example, based on the word retrieved out of an identification word table 4 when no identification word is inputted to an identification word holding part 3 within a prescribed time even though the ID information on a user is stored in an ID holding part 2. Then the produced insignificant words (pseudo identification words unable to function as identification words) are displayed at a display part 8 together with the registered identification word for the user. As a result, the user can easily remind the registered identification word based on the information on the displayed pseudo identification words even if the user forgets the registered identification word. Thus the registered identification word can be inputted correctly. |
