<P>PROBLEM TO BE SOLVED: To maintain successful authentication even if the recognition of an authentication device is interrupted except by theft. <P>SOLUTION: Even after successful authentication of the authentication device 905, an authentication device recognition part 121 periodically checks whether or not the authentication device 905 can be recognized. The successful authentication is maintained as long as the authentication device recognition part 121 can recognize the authentication device 905. If the authentication device recognition part 121 fails to recognize the authentication device 905, on the other hand, a screen for receiving the input of an emergency password 9053 is displayed on a touch panel display of an operation part 119. When the operator inputs the emergency password 9053, the emergency password 9053 received on the screen is checked. If the received emergency password 9053 is authenticated, the successful authentication is maintained to continue job execution. <P>COPYRIGHT: (C)2008,JPO&INPIT |
